After assembly, at least some of the protrusions 211, 211' of the spool part are arranged in contact with the sealing member of the valve body part. The wall of the conducting part can be in a streamline design to reduce the resistance when the fluid flows through.

As shown in fig. 5, the control valve of the present embodiment further includes a sealing element 42 and an elastic pad 41, the sealing element 42 and the elastic pad 41 of the present embodiment are two components, the sealing element 42 has a second through hole 421 and a limiting portion 422, the limiting portion 422 is respectively located at two sides thereof, the limiting portion 422 is in an outward protruding structure or an outward turning structure, and can further limit two sides of the elastic pad to limit a deformation range of the elastic pad after extrusion, so that a position of the second through hole corresponds to a position of the first through hole. The number of the second through holes 421 corresponds to the number of the communication ports, and after assembly, one second through hole is respectively matched with the communication ports to communicate the fluid. The elastic pad 41 has first through holes 411, the number of the first through holes 411 corresponds to the communication ports, and the positions of the first through holes 411 and the second through holes 421 correspond to the communication ports, respectively, so as to allow fluid to flow through. The sealing member 42 and the elastic pad 41 may be formed as an integral structure by two-shot molding, or a combination of the two may be formed by injection molding or potting based on the sealing member. The resilient pad 41 is resilient so that, when assembled, the valve core member and the valve body member can be disposed in a partially interference relationship, and the projection of the valve core member contacts the inner surface of the seal member by deforming the resilient pad, thereby providing a relative seal. The elastic cushion can ensure that the sealing element and the valve core component can still keep contact and sealing when the valve core component and the sealing element are abraded to improve the service life.

When the system is used, one or more than two working modes can be selected by the system, particularly, the selection and the control can be carried out according to the system requirements, and if the system exists, 4 conduction modes including a first working mode (a), a second working mode (b), a third working mode (c), a fifth working mode (e) and the like can be selected to operate; in addition, the conduction mode is not limited to the above mode according to the system requirement, and the combination form of the conduction parts of the valve core can be changed to have different conduction modes.

In this embodiment, referring to fig. 3 and fig. 3a, fig. 3b, and fig. 4, the valve core component and the communication port of the valve body component are communicated in a matching manner, the outer wall of the valve core part is provided with protrusions 211 and 211 'which protrude outwards, namely the protrusion 211 surrounding the first conduction part 221 and the protrusion 211' surrounding the second conduction part 222, when the control valve is in a specific operation mode, as shown in an operation mode shown in figure 3, the protrusion 211 is in contact with the surface of the seal 42, and the elastic pad 41 has elasticity, and when the valve body member is in contact with the seal, the elastic pad is deformed by an appropriate amount, and by the provision of the protrusion 211, therefore, the space between the valve body member and the valve body member, in which the first conduction portion 221 and the fourth port 104 are communicated with each other through the third port 103 and the fourth port 104, is relatively isolated from the space other than the communicated space. And the valve core part contacts with the valve body part through the protruding part, and the outer wall of the valve core part and other parts of the inner wall part of the valve body part can have a certain gap when rotating, so that the power required by the rotation of the valve core part is relatively small, and if impurities exist in the fluid, the impurities can be taken away through the gap when rotating. The elastic pad can be made of rubber material, such as ethylene propylene diene monomer EPDM or silicon rubber, or other elastic materials. The sealing element can be made of plastic materials through injection molding, such as fluoropolymers such as polyvinylidene fluoride (PVDF) and polyvinylidene fluoride (PVDF) or other high-molecular polymers, and can also be made of metal plates through stamping, such as stainless steel plates, wherein the thickness of the materials can be 0.3mm-0.6 mm.

The sealing of the conducting portion between the valve body member and the valve core member of this embodiment is realized by providing the protruding portion on the valve core member, or alternatively, the protruding portion may be provided on the inner wall portion of the corresponding portion of the valve body member, for example, one protruding portion is provided on the sealing member around each of the eight communication holes, so that the relative sealing can be realized, and thus, the protruding portion for fitting sealing is not required to be provided on the outer wall portion of the valve core member.

The control valve of the above embodiment has 8 ports, and the communication condition can be changed correspondingly under different conditions, and if the first conduction part is 3, the communication condition will be different. In addition, the number of the ports of the control valve can be more than 5, and as shown in fig. 10, the communication condition of the ports of the second embodiment of the control valve is schematically shown, and the control valve has 7 ports: a first interface 101, a second interface 102, a third interface 103, a fourth interface 104, a fifth interface 105, a sixth interface 106, and a seventh interface 107; compared with the embodiment, the valve core component has 3 first conduction parts and two second conduction parts, and the control valve has 5 working modes:
