Technical Field

The invention relates to a wall-mountable sanitary conduit connection device having a wall-mountable base body and a valve which can be fastened to the base body.

Background

In particular, conduit connection devices of this kind are used in sanitary engineering, on the one hand, as water supply facilities on the building side and, on the other hand, as interfaces between end-user devices, such as shower devices and sanitary outlet faucets or outlet fittings on washstands, bathtubs, kitchen sinks and the like. They are conventional in both surface mount and concealed designs, e.g. as so-called surface mount or concealed boxes, either of the types discussed herein having integrated or in embodiments no valves. Such conduit connection devices are often also used as so-called water plugs. Wall-mountable is here understood to mean that the sanitary conduit connection device is intended and designed to be able to be mounted on a building side wall, in particular on a wall area in which there is a building-side water-utility connection point. The term wall will here be generally understood as a building side surface which is suitable for the installation of the pipe connection device and which may be both a real vertical wall surface of a building and also a ceiling surface or a floor surface.

Disclosure of Invention

The present invention solves the technical problem of providing a wall-mountable sanitary conduit connection device of the initially mentioned type and which provides an improvement with respect to the above-mentioned prior art in terms of flexibility of use, compact design, manufacturing costs and/or possible applications in modern sanitary systems, including systems with water plugs and systems for sanitary smart home applications.

The present invention solves this problem by providing a wall-mountable sanitary conduit connection device having the features of claim 1. The conduit connection device comprises a wall-mountable base having a receiving sleeve and a water inlet conduit which opens peripherally into the receiving sleeve with an inlet conduit outer flow. The conduit connection device also includes an electrically controllable valve having a cylindrical valve element axially insertable into the receiving sleeve. The valve unit is located in the valve cartridge, and the valve cartridge has an electric valve connection unit on a first end face and a pipe connection coupling on a second end face. The valve cartridge further comprises a valve inlet opening on the peripheral side, which valve inlet opening can be coupled in a liquid-tight manner to the inlet conduit outflow of the water inlet conduit. The conduit connection device comprises a fastening unit with which the valve cartridge can be fastened in a fixed position in the receiving sleeve.

By virtue of this design, the conduit connection device can be flexibly used for various applications, in particular also in modern sanitary devices of the smart home type or in sanitary systems with water plugs. By using an electrically controllable valve, the water flow in the conduit connection can be electrically controlled, which in particular permits remote control of the water flow, so that direct access to the conduit connection for the purpose of actuating the valve is not absolutely necessary. In particular, the valve may be a shut-off valve, alternatively another type of valve, such as a mixing valve or a switching valve, for which purpose the valve may then have one or more additional valve inlet openings and/or valve outlet openings, respectively.

By using a valve with a cylindrical valve insert which can be inserted into a receiving sleeve of the base body, the conduit connection device can be flexibly equipped with the respectively required valve as required and then inserted together with its valve insert into the receiving sleeve. The fastening unit ensures that the valve cartridge is fastened in a fixed position in the receiving sleeve and thus ensures the desired mechanical strength of the connection of the valve and the base body as required.

It is also advantageous to have a valve slide with an electrically actuated valve connection unit on one end face and a tube connection on the other end face, and with a valve inlet opening formed on the outer periphery. The pipe connection coupling on the second end face of the valve cartridge here forms the outlet opening of the valve, to which it is possible to couple in a desired manner a pipe, such as a shower device or a water outlet fitting, for example in the form of a conventional mixer fitting or an outlet tap, in particular leading to a sanitary end user. The term pipe will be understood herein to mean a rigid water duct leading to the shower body or shower head and also a flexible water duct line (e.g. a rigid pipe connection) or a flexible shower hose leading to the shower head. The fixed fastening of the valve cartridge in the receiving sleeve by means of the fastening unit can, if desired, provide a sufficiently high mechanical load-bearing capacity, which is of the kind required for the direct coupling of shower heads or shower arms provided with connections (for example, for overhead shower heads or wall-mounted overhead shower heads or side shower heads in shower cubicles).

In a development of the invention, the fastening unit has a bayonet connection unit which has a radially projecting bayonet connection bead on the peripheral side of the valve slide and a bayonet connection shoulder on the receiving sleeve which can be engaged from behind by the bayonet connection bead of the valve slide. This constitutes a very advantageous configuration of the fastening unit. After the valve cartridge has been pushed axially into the receiving sleeve, it can be secured firmly in the receiving sleeve by a bayonet rotational movement in this way. Since the bayonet connection is releasable in principle, the cartridge can be removed again from the receiving sleeve if necessary, for example for the purpose of cleaning or replacement with another cartridge.

In one embodiment of the invention, the fastening unit has a bayonet lock for the bayonet connection unit. The bayonet lock has an axial portion peripheral bore on each of an inner circumference of the receiving sleeve and an outer circumference of the spool, and has an anti-rotation bolt. An axial partial peripheral bore is to be understood here to mean that it forms only a part of a bore which extends completely axially in the circumferential direction, i.e. extends with its bore edge less than 360 °. The two partial peripheral bores are adapted in shape to one another in such a way that they are aligned with one another so as to form a full bore (i.e. a full bore in the circumferential direction) into which the anti-rotation bolt can be inserted only in the fastening position of the bayonet connection unit, in which the bayonet connection unit fastens the valve cartridge in a fixed position in the receiving sleeve. Thus, with the anti-rotation bolt inserted, the valve cartridge is secured or locked in its bayonet connection rotational position against inadvertent transfer back into the bayonet release direction.

In one embodiment of the invention, the valve cartridge has a sealing ring which annularly surrounds the valve inlet opening and extends in the circumferential direction of the valve cartridge over a bayonet rotational angle range which is further away than the valve inlet opening. This has the advantage of avoiding a situation in which the sealing ring rotates past the inlet duct outflow of the water inlet duct during the bayonet rotational movement, thereby excluding any risk of the sealing ring being damaged on sharp edges of the inlet duct outflow of the water inlet duct. During a complete bayonet rotational movement, the sealing ring completely surrounds the mouth area of the inlet duct outer flow without crossing or straddling the edge of the mouth.

In a development of the invention, the receiving sleeve has an open sleeve shape which spans a free angle on the peripheral side, and the valve slide has a radially projecting alignment flange on the peripheral side, which alignment flange extends across a circumferential angle corresponding to the free angle and which alignment flange is located axially outside the receiving sleeve (i.e. behind the receiving sleeve, i.e. extends axially beyond the receiving sleeve) when the valve slide is fully inserted axially. This enables positioning for the spool to be inserted into the receiving sleeve, which positioning is oriented in the direction of rotation. The valve slide can be pushed axially into the receiving sleeve only in a rotational position in which the alignment collar of the valve slide is located in a circumferential portion of the receiving sleeve that is not open in the sleeve shape. Only when the valve slide is pushed fully axially into the receiving sleeve does the alignment collar of the valve slide pass axially beyond the receiving sleeve, so that the valve slide can be rotated, for example in order to permit the stated bayonet rotational movement when the fastening unit has a bayonet connection unit.

In a development of the invention, the receiving sleeve has a corresponding conical surface on the inner circumference and the valve slide on the outer circumference, which tapers in the valve slide insertion direction. This contributes to a precise axial fastening of the valve cartridge in the receiving sleeve and to a high degree of mechanical strength of the fastening of the valve cartridge in the receiving sleeve. Furthermore, in configurations in which the sealing ring surrounds the valve inlet opening in an annular manner, these conical surfaces have the following effect: during axial insertion of the valve cartridge into the receiving sleeve, the axial guide ring portion of the sealing ring can move axially over the edge of the inlet pipe outer flow portion of the water inlet pipe without already bearing against this edge, so that any risk of the sealing ring being damaged by the edge of the inlet pipe outer flow portion of the water inlet pipe is again avoided. For this purpose, the conical surface then extends at least also in the region of the sealing ring or of the inlet duct outflow of the water inlet duct.

In a development of the invention, the valve slide has a rotary tool receptacle on its second end face, i.e. a receptacle for a tool with which the valve slide can be rotated. This is advantageous, for example, for configurations in which the fastening unit has a bayonet connection unit. In this case, the valve slide can be turned by the tool after axial insertion into the receiving sleeve in order to achieve a bayonet rotational movement and can thus be fastened firmly and with a high degree of strength in the receiving sleeve. On its second end face, the valve cartridge is easily accessible by the tool, since this is the end face of the valve cartridge on which the pipe connection coupling of the valve cartridge is located, and therefore the purpose of attaching this pipe connection coupling has been to ensure that this end face of the valve cartridge is easily accessible.

In a development of the invention, the valve cartridge has an axial cable guide on the outer circumference for guiding at least one electrical connection cable from the first end face to the second end face. In this way, the electrical connection cables, which usually lead out of the electrically operated valve connection unit on the first end face, can be routed to the second end face, which is particularly advantageous if the second end face of the valve cartridge is more easily accessible than the first end face, when the valve cartridge is fastened in the receiving sleeve of the base body. In this case, the first end face of the spool does not necessarily have to remain accessible.

In a development of the invention, the base body has a wall-mountable base plate and a socket body (socket body) which is fixed to the base plate and comprises a receiving sleeve, a water inlet and a water inlet duct leading from the water inlet to an inlet duct outflow. This constitutes a multi-part configuration of the base body, which is advantageous from the point of view of manufacturing technique and assembly. The base may be mounted on a desired wall surface via a base plate and the socket body may be fixed (e.g. releasably) on the base plate as such, wherein the receiving sleeve, the water inlet and the water inlet conduit are prefabricated on the socket body.

In a development of the invention, the water inlet conduit is oriented with the longitudinal direction of its water inlet perpendicular to the longitudinal direction of the receiving sleeve. This is advantageous, for example, for a pipe connection in which the building-side water utility connection ends with an end connection of the wall oriented parallel to its longitudinal axis, and the pipe leading perpendicularly from the wall surface is intended to be connected to the pipe connection, more particularly to the pipe connection coupling of the valve cartridge. Furthermore, in this embodiment, the base body can be realized with a relatively small installation depth (i.e., a small range in the wall depth direction perpendicular to the wall surface).

In a development of the invention, the base body has an empty tube receptacle for an empty tube, which can be used to receive the electrical line. This permits a simple cable feed for the electrically controllable valve.

In a development of the invention, the base body forms a connection box (connection box) with a box housing cover. The cartridge housing cover protects the interior of the base including the valve and may also serve as an optical cover. In particular, the junction box is suitable as a concealed box for a concealed type configuration of a conduit connection device.

Detailed Description

The wall-mountable sanitary conduit connection depicted in the figures comprises a wall-mountable base 1 with a receiving sleeve 2 and a water inlet conduit 3, and also an electrically controllable valve 4 with a cylindrical valve cartridge 5 axially insertable into the receiving sleeve 2, and a fastening unit 6 for fastening the valve cartridge 5 in a fixed position in the receiving sleeve 2. For mounting on the wall, the base body 1 is provided with suitable fastening means. In the example shown, these are fastening screws 15, but for this purpose other conventional wall fastening means are used instead, which need not be explained further here.

The water inlet conduit 3 opens peripherally into the receiving sleeve 2 through an inlet conduit outflow 7. The valve cartridge 5 comprises on the peripheral side (i.e. on the cylindrical jacket surface) a valve inlet opening 8 which can be coupled in a liquid-tight manner to the inlet conduit outer flow 7 of the water inlet conduit 3. Such a liquid-tight coupling is obtained when the spool 5 is fastened in a fixed position in the receiving sleeve 2 by means of the fastening unit 6, i.e. when the spool 5 is in its position of use in the receiving sleeve 2.

Located in the valve spool 5 is a valve unit 9, for example of the conventional electrically controllable solenoid valve type and/or diaphragm valve type or any other desired conventional electrically controllable valve type, depending on requirements and specific use, which need not be explained further here. The valve body 5 has an electrically operated valve connection means 11 on the first end surface 10. On the second end face 12, the valve slide 5 has a pipe connection coupling 13. Thus, the pipe connection coupling 13 forms an axial valve outlet of the valve 4 on the second end face 12 and can be realized, for example, by a connecting internal thread into which the pipe 14 to be connected (as shown in fig. 2) can be screwed, preferably with standardized fitting dimensions (such as 1/2 inch or 3/4 inch threaded couplings). Alternatively, connecting external threads or other types of connecting couplings may be used for the pipe connecting coupling 13, such as a bayonet connecting coupling or a plug-in connecting coupling. The valve is preferably configured as a shut-off valve, or alternatively it is another valve type, such as a switching valve or a mixing valve, with suitable further valve inlets and/or valve outlets.

For mounting the valve 4, it is pushed with its valve slide 5 (the first end face 10 of which is axially to the front) into the receiving sleeve 2 of the base body 1 and is then fastened in a fixed position in the receiving sleeve 2 by means of the fastening unit 6. In a corresponding embodiment, for this purpose, as in the example shown, the fastening unit 6 has a bayonet connection unit with a radially projecting bayonet connection lug 6a on the peripheral side of the valve slide 5 and a bayonet connection shoulder 6b on the receiving sleeve 2, which can be engaged from behind by the bayonet connection lug 6 a.

In this advantageous configuration, after being pushed axially into the receiving sleeve 2, the valve slide 5 is accordingly secured in a fixed position in the receiving sleeve 2 by means of a customary bayonet rotational movement. Since in this fastening position of the bayonet connection unit the bayonet connection flange 6a of the valve cartridge 5 engages behind the bayonet connection shoulder 6b of the receiving sleeve 2, in particular the valve cartridge 5 is fastened in a manner preventing axial removal from the receiving sleeve 2. In an alternative embodiment, the fastening unit 6 is another conventional type of connection, for example using a screw connection or a snap-fit connection.

In an advantageous embodiment, the bayonet connection lug 6a and/or the bayonet connection shoulder 6b have a continuous (run-on) bevel (in the example shown the bayonet connection lug 6 a), so that, due to the wedging force generated by the continuous bevel, the valve cartridge 5 can be pressed or pulled axially by means of a bayonet rotational movement into a fastening position in the receiving sleeve 2.

In an advantageous embodiment, as in the example shown, the receiving sleeve 2 has on its inner circumference and the valve slide 5 on its outer circumference corresponding conical surfaces 2a, 5a tapering in the valve slide insertion direction, preferably through corresponding truncated conical surfaces in the respectively associated axial section of the receiving sleeve 2 or of the valve slide 5. This configuration can be easily combined with the above-described embodiment of the fastening unit 6 as a bayonet connection unit. By means of the bayonet rotational movement, as mentioned above, the valve cartridge 5 can additionally be pressed axially in the push-in direction relative to and against the receiving sleeve 2, as a result of which the valve cartridge 5 bears with its outer cone surface 5a against a corresponding cone surface 2a on the inner face of the receiving sleeve 2. This results in a very stable and stable retention of the valve slide 5 in the receiving sleeve 2.

In the configuration of the fastening unit 6 as a bayonet connection unit, the fastening unit is optionally provided with a limit stop of the bayonet rotational movement, for example by the bayonet connection flange 6a of the valve cartridge 5 bearing with its front edge in the bayonet rotational direction against a corresponding limit shoulder on the receiving sleeve 2.

In an advantageous embodiment, as in the example shown, the fastening unit 6 has, in its configuration as a bayonet connection unit, a bayonet lock which ensures that an inadvertent rotation of the bayonet back into the fastening position and thus an inadvertent release or loosening of the valve cartridge 5 fastened in the fixed position in the receiving sleeve 2 is prevented. For this purpose, the bayonet lock has an axial partial peripheral bore 16a on the inner circumference of the receiving sleeve 2 and a corresponding axial partial peripheral bore 16b on the outer circumference of the valve slide 5, and also an anti-rotation bolt 16 c. The two partial peripheral bores 16a, 16b are aligned only in the fastening position of the bayonet connection unit, so that a full bore is formed, into which the anti-rotation bolt 16c can then be inserted.

The following such situations are shown for example in fig. 1 to 3, 5 and 6 and are clear from fig. 1 to 3, 5 and 6: the valve cartridge 5 has been mounted in the receiving sleeve 2 and the bayonet connection is locked by means of the inserted anti-rotation bolt 16c, while the following are illustrated in fig. 4 and 10 to 12: the valve core 5 is pushed into the receiving sleeve 2 before the final bayonet rotation. In particular, it will be seen from fig. 12 that in this case the two partial peripheral holes 16a, 16b are still offset in the direction of rotation and are therefore misaligned so as to form a full hole. Only when the valve cartridge 5 is rotated from this position to the final fastening position by means of a bayonet rotational movement, the two partial peripheral bores 16a, 16b are aligned and thus form a full bore into which the anti-rotation bolt 16c can then be inserted. When the anti-rotation bolt 16c is inserted into the full bore, it prevents the partial peripheral bore 16b of the spool 5 from rotating away from the partial peripheral bore 16a of the receiving sleeve 2 and thus locks the spool 5 against rotation back to the bayonet release position.

In an advantageous configuration, the two partial peripheral holes 16a, 16b are designed as partial peripheral threads which, in their aligned position, provide corresponding full threads into which the anti-rotation bolts 16c (which are then suitably configured as screw bolts) can be screwed. For example, the two part peripheral holes 16a, 16b may each be designed as a half-circumferential thread, which extends 180 ° in the circumferential direction and which, in the aligned position, are complementary to one another to form a full thread. In a further advantageous configuration, as in the example shown, one of the two partial peripheral holes 16a, 16b of the spool 5 (for example, as shown, the partial peripheral hole 16 b) is designed as a partial peripheral thread extending over 180 °, while the other partial peripheral hole is not threaded. In this case, the anti-rotation bolt 16c is also correspondingly designed as a screw bolt which can be screwed into the full bore when the two part peripheral bores 16a, 16b are in their aligned position. The rotation-prevention bolt 16c is guided in the thread of the associated partial peripheral bore, for which purpose the partial peripheral bore extends with its thread in the circumferential direction over slightly more than 180 °, whereas the partial peripheral bore which is not provided with a thread merely provides the necessary remaining space for the rotation-prevention bolt 16c and accordingly extends in the circumferential direction over slightly less than 180 °. Thus, in this embodiment, only one of the two partial peripheral holes 16a, 16b needs to be made threaded.

To remove the valve cartridge 5, the anti-rotation bolt 16c is first pulled out of the full bore (e.g. unscrewed), after which the valve cartridge 5 can be rotated back into the bayonet release position and can then be pulled out axially from the receiving sleeve 2.

In an advantageous embodiment, as in the example shown, the valve slide 5 has a rotary tool receptacle 17 on its second end face 12, as can be seen in fig. 9. A matching tool can be inserted into this receptacle 17, with which tool the valve cartridge 5 can be rotated, in particular for a bayonet-rotary movement to rotate the valve cartridge 5 into its final fastening position and back into its bayonet-release position. For example, as shown, the turning tool receptacle 17 may be configured as a polygonal receptacle (in particular, a hexagonal receptacle), or alternatively as another conventional turning tool receptacle, such as a cross-slot type or a simple longitudinal slot type, for attaching a corresponding screwdriver. Optionally, as in the example shown, the internal valve unit 9 is protected against too far forward axial movement of the tool by an axial tool stop 18, said tool stop 18 being located at the axial rear end of the rotary tool receptacle 17, as can likewise be seen in fig. 9. The tool stop 18 may be formed, for example, by a simple central or transverse web which spans the rotary tool receptacle 17 at its inner end facing the valve unit 9.

In corresponding embodiments, as inIn the example shown, the receiving sleeve 2 has a free angle F of traversal on the peripheral side_WI.e. it extends in the circumferential direction over a circumferential angle smaller than 360 deg. by a free angle F_WBut is preferably greater than 180. In correspondence with this, the spool 5 has, on the peripheral side, a radially projecting alignment flange 19 which spans in correspondence with the free angle F_WCircumferential angle A of_WExtends and, when the spool 5 is fully inserted axially, the alignment flange reaches behind (i.e. axially beyond) the receiving sleeve 2 so that it then does not hinder rotation of the spool 5 in the receiving sleeve 2. However, for as long as the valve slide 5 has not yet been pushed completely axially into the receiving sleeve 2, the alignment collar 19 prevents the valve slide 5 from rotating in the receiving sleeve 2, and the alignment collar 19 furthermore has the following effect: the valve slide 5 can only be pushed axially into the receiving sleeve 2 when it is in a very defined rotational position relative to the receiving sleeve 2. This is the rotational position in which the alignment flange 19 is aligned with the open circumferential portion of the receiving sleeve 2, for which purpose the open circumferential portion of the receiving sleeve 2 spans the same angle (in particular the free angle F) in the circumferential direction as the alignment flange 19_W) Extending across a corresponding circumferential angle A_WAnd (4) extending. In a corresponding embodiment, as in the example shown, the bayonet connection lug 6a is part of the alignment lug 19, or alternatively it is arranged separate from the alignment lug.

In an advantageous embodiment, as in the example shown, the valve slide 5 has a sealing ring 20 which annularly surrounds the valve inlet opening 8 and extends in the valve slide circumferential direction over a bayonet rotational angle range D which is further than the valve inlet opening 8_W. It is thus possible to avoid situations in which the sealing ring 20 comes into contact with or moves along the edge of the inlet duct outflow 7 when the valve cartridge 5 is rotated in the receiving sleeve 2 by a bayonet rotational movement.

For example, as can be seen from fig. 12, during the axial insertion of the valve cartridge 5 into the receiving sleeve 2 in the intended rotational position of the valve cartridge 5, the sealing ring 20 is already completely outside the inlet duct outflow 7 and moves rotationally throughout the bayonetIt also remains outside the inlet duct outflow 7 and its boundaries. For this purpose, it extends in the direction of rotation beyond the bayonet rotational angle range D of the valve inlet opening 8_WThe valve inlet opening 8 is offset relative to the inlet duct outer flow 7 by the bayonet rotational angle prior to bayonet rotational movement and in fluid conducting alignment with the inlet duct outer flow 7 by the bayonet rotational movement. Thus, when the cartridge 5 is mounted in the receiving sleeve 2, any sharp edges at the boundary of the inlet duct outflow 7 do not lead to damage of the sealing ring 20.

Furthermore, in an advantageous embodiment, as in the example shown, the sealing ring 20 and the inlet duct outflow 7 are located in the region of the respective conical surface 5a, 2 a. In this way, during the axial insertion of the valve cartridge 5 into the receiving sleeve 2, the sealing ring 20 can be moved axially with its axial front portion over the inlet duct outer flow portion 7 without coming into contact with or being pressed against its boundary surface. This prevents any damage to the sealing ring 20.

In an advantageous embodiment, as in the example shown, the valve slide 5 has an axial cable guide 21 on the outer circumference for guiding at least one electrical connection cable 22 from the first end face 10 to the second end face 12 of the valve slide 5. Thus, the first end face 10 of the valve cartridge 5 need not remain accessible for electrical connection purposes when the valve cartridge 5 is inserted into the receiving sleeve 2. As shown, the cable guide 21 may have, for example, a conventional type cable clamp holder formed on the outer circumference of the spool 5. In the example shown, the cable guide 21 or clip holder is configured as part of the alignment flange 19. In an alternative embodiment, this is achieved independently of the presence of the alignment flange 19.

In the example shown, the cable guide 21 has, for example, two clip retainer units 21a, 21b as part of the alignment flange 19, wherein one clip retainer unit 21a holds the depicted connecting cable 22 leading out of the electrically operated valve connection unit 11 on the first end face 10 of the valve cartridge 5, while the other clip retainer unit 21b serves to hold an electrical cable routed from the outside to the conduit connection, which can then be electrically connected to (e.g. plugged into) the depicted connecting cable 22 of the valve 4 in an easily accessible region on the second end face 12 of the valve cartridge 5.

In a corresponding embodiment, the base body 1 has a wall-mountable base plate 23 and a socket body 24 which is fixed to the base plate 23 and has a receiving sleeve 2, a water inlet 3a and a water inlet conduit 3 leading from the water inlet 3a to the inlet conduit outflow 7. The socket body 24 may be screwed onto the base plate 23, for example as represented in fig. 6 by the associated threaded connection 25.

In a corresponding embodiment, as in the example shown, the longitudinal direction L of the water inlet 3_EWith respect to the longitudinal direction L of the receiving sleeve 2_HOriented vertically. In the exemplary embodiment shown, the longitudinal direction L of the receiving sleeve 2 and thus also of the valve slide 5 fastened therein in a fixed position is the longitudinal direction L_HAs such, is oriented perpendicularly with respect to the base plate 23, while the water inlet longitudinal direction L_EOriented parallel to it.

In a corresponding embodiment, as in the example shown, the base body 1 has an empty tube receptacle 26 for an empty tube 26a for the routing of one or more electrical lines (for example, lines for electrically coupling the valve 4 via its connection cable 22).

In a corresponding embodiment, as in the example shown, the base body 1 forms a terminal box with a box housing cover 27. The cartridge housing cover 27 preferably has a cutout through which the valve cartridge 5 remains accessible at its second end face 12 and thus connects the coupling 13 with its tube there, so that a tube (e.g. tube 14) can be coupled to the valve cartridge 5 and detached therefrom again, while the cartridge housing cover 27 does not necessarily have to be removed for this from the rest of the base body (e.g. the base plate 23 on which the socket body 24 is fixed).

For example, in fig. 2 can be seen a cavity 28 of the base body 1, which cavity 28 is covered by a cassette housing cover 27 and can be used, for example, as a stowage space or for accommodating conventional electrical or electronic components (such as sensors, bluetooth modules, etc.) of electrical cables (not shown) and/or sanitary catheter connection devices, depending on requirements.

Optionally, a sealing body 30 can be used, which ensures that the base body 1 is liquid-tight and at the same time can provide integrated acoustic decoupling. To this end, the sealing body 30 may extend with corresponding portions as a planar partition between the base plate 23 and the socket body 24, and/or may be a flat plate covering the base plate, and/or may surround the receiving sleeve 2, and/or may separate a space in front of the open circumferential portion of the receiving sleeve 2 from a space behind it, as shown in the case of two flanks 30, 30 b.

As illustrated by the exemplary embodiments shown and explained above, the present invention advantageously makes available a wall-mountable sanitary conduit connection which has great flexibility in use, can have a compact structure (if so desired), can be manufactured at relatively low cost, and can be used in modern sanitary systems including water-stoppered systems and smart home systems.
