Technical Field

The invention belongs to the technical field of valves, and relates to a coded lock and a valve with the coded lock.

Background

At present, valves having locking devices have been widely used in water supply lines, heating lines, or gas lines, which can be managed by community property or water companies. One of the valve structures with a locking device is a mechanical lock, such as a flanged ball valve with an on-off locking mechanism disclosed in patent application No. 201320250578.3, which can be locked by hanging the mechanical lock on the valve through changing the valve structure. The mechanical lock has the defects that the mechanical lock can be opened only by using a key, and when the number of the lock control valves is large and the key of each lock cannot be used universally, the mechanical lock is very unfavorable for centralized management.

The valve with locking device also has a structure adopting magnetic locking, for example, the magnetic locking valve disclosed in patent application No. 200920313315.6, which is characterized in that a valve body is connected with a locking cap, a magnetic locking mechanism is arranged between the locking cap and the valve body, the locking of the valve is realized by utilizing the magnetic locking mechanism, and a magnetic key which can be sleeved on the locking cap and can unlock the magnetic locking mechanism by means of magnetism is also arranged. Compared with the additionally-hung mechanical lock, the magnetic key can control the valves of the same type, the number of keys is reduced, and centralized management is facilitated to a certain extent. However, the magnetism of the magnetic component in the valve is weakened after long-term use, which results in lower reliability, and more importantly, a universal magnetic key which can be commonly used on various magnetic locking valves appears in the market at present, which results in weaker opening prevention.

Aiming at the problems of low reliability and poor unlocking prevention, one of the conventional technical means of the technical personnel in the field is to use a password type mechanical padlock instead of a mechanical lock unlocked by a key, and the mechanical lock has the same good unlocking prevention performance and does not need the key when being unlocked; still another is to integrate the structure of the combination lock directly into the valve, such as a combination lock valve disclosed in patent application No. 201320430411.5, a combination gate valve disclosed in patent application No. 201020607376.6, a combination lock of a valve disclosed in patent application No. 201210282803.1, and the like.

Disclosure of Invention

The invention aims to provide a coded lock and a valve with the coded lock aiming at the problems in the prior art, and solves the problems of low reliability and poor opening prevention performance of the valve with a locking function.

The purpose of the invention can be realized by the following technical scheme:

the coded lock comprises a lock body and a coded lock box connected to the surface of the lock body, wherein the lock body is of a cylindrical structure with an upper end closed and a lower end opened, the coded lock is characterized in that the lock body comprises a first petal body and a second petal body which can be spliced into the cylindrical structure, a locking structure which can fix the first petal body and the second petal body and is controlled by the coded lock box is arranged between the first petal body and the second petal body, and a shoulder is arranged on the inner side of the lower end of the first petal body and/or the second petal body.

The coded lock is mainly applied to a valve to realize a locking function, for example, a common gate valve is used, a hand wheel connected to a valve rod of the gate valve is taken down firstly, then a first petal body is abutted against the outer side of the upper end of a valve body of the gate valve and ensures that the valve rod is positioned at the inner side of the first petal body, and then a second petal body and the first petal body are spliced and fixed through a locking structure, so that the first petal body and the second petal body are combined into a lock body with a cylindrical structure with the upper end closed and the lower end open, and a blocking shoulder at the inner side of the lower end of the first. Therefore, the valve rod is hidden in the lock body and cannot be operated, the pressing cap which is connected to the upper end of the valve body in a threaded mode is located in the lock body, the coded lock cannot be taken down from the valve body due to blocking of the pressing cap on the blocking shoulder, and the locking structure cannot be controlled to be opened under the condition that the correct password cannot be input into the coded lock box, so that the locking of the valve is achieved, and meanwhile the reliability of opening prevention and use is improved.

No matter a password type mechanical padlock or a password type mechanical lock body structure integrated on the valve is adopted, the valve structure needs to be greatly changed, so that the condition that the locking part cannot be separated from a special valve and is directly applied to a common valve is caused, namely the universality is poor. This trick lock neither directly integrates on the valve, does not require a pair of lockholes of matched with on the valve like the padlock simultaneously again, what adopt only wrap the valve rod through the concatenation mode and hide outside the valve body upper end to only need block the shoulder with the help of the structure of taking on the valve certainly and can make the trick lock directly take off from the valve, improved the commonality of this trick lock from this well.

In the coded lock, the blocking shoulder is arc-shaped.

When the connected valve is a gate valve, the arc shape enables a larger blocking area to be formed between the blocking shoulder and the pressing cap on the gate valve, so that the coded lock can be stably connected to the valve, and the opening prevention performance is further improved. When the connected valve is a ball valve, the valve rod of the valve extends out of the upper end of the valve body of the valve and is connected with a handle, and the upper end of the valve body is externally provided with a limiting block for limiting the rotation angle of the handle. The blocking shoulder is arranged to be arc-shaped, the arc-shaped shape enables the blocking shoulder to be effectively matched with the limiting block outside the upper end of the ball valve body, the coded lock can also be connected to an ordinary ball valve to achieve a locking function, and the universality of the coded lock is further improved. Except for a common gate valve or a common ball valve, the coded lock can be locked by adopting the structure which can be matched with the arc-shaped retaining shoulder on other common valves.

In the coded lock, the inner side of the lower end of the first petal body and the inner side of the lower end of the second petal body are respectively provided with a retaining shoulder, and when the first petal body and the second petal body form a lock body, the two retaining shoulders can be spliced into a circular ring-shaped structure.

The blocking shoulder on the inner side of the lower end of the petal body and the blocking shoulder on the inner side of the lower end of the petal body are spliced into a circular ring when the lock body is formed, so that the coded lock can be more stably connected with the valve, and the anti-opening effect is better.

In foretell trick lock, the lamella body one all be circular arc platelike with the lamella body two, the upper surface of the lamella body one links firmly circular roof or the upper end inboard of the lamella body one and the upper end inboard of the lamella body two all link firmly semi-circular baffle.

When the second petal body and the first petal body are spliced and fixed through the locking structure to form the lock body, the lock body can be in a cylindrical structure with the upper end closed and the lower end opened through the circular top plate or the combination of the two semicircular baffles fixedly connected to the upper surface of the first petal body, so that the valve rod exposed outside is hidden to realize locking, and the opening prevention performance is improved. This form not only ensures the normal locking function, but also makes the combination lock universal on the common valve.

In foretell trick lock, lamella body one and lamella body two be monolithic structure, perhaps the lamella body one includes main part one and links firmly in the connector one of main part one lower extreme, lamella body two includes main part two and links firmly in the connector two of main part two lower extremes, keep off the shoulder and locate on connector one and connector two.

The first valve body and the second valve body are arranged into a split structure, the valve with the same structure is mainly considered to have various specifications, and the coded lock mainly depends on the retaining shoulder to ensure that the coded lock cannot be directly taken down from the valve body, so that the size of the first main body and the size of the second main body are not limited by the specifications of the valve, namely, the first main body and the second main body can be directly produced in batches at one time, and therefore the production of enterprises is simpler.

In the coded lock, one side of the first petal body is hinged with one side of the second petal body, and the locking structure is positioned between the other sides of the first petal body and the second petal body. This arrangement facilitates both opening and closing of the lock body.

In the above coded lock, the locking structure comprises a lock tongue arranged in the first petal body in a sliding manner and a bayonet arranged on the second petal body, a lock hook extending out of the first petal body is arranged on the side part of the lock tongue, the lock tongue can enable the lock hook to be hooked on the side wall of the bayonet under the action of self elasticity or a supporting spring, and one end of the lock tongue penetrates out of the coded lock box and can limit the lock tongue to slide when the coded lock box is locked.

The lock tongue makes the latch hook collude on the lateral wall of bayonet socket under the effect of self elasticity or a supporting spring, and the trick lock box restricts the slip of lock tongue when locking simultaneously, just so can't make latch hook and bayonet socket throw off through pressing down the lock tongue, has realized the locking from this. When the coded lock box is unlocked, the sliding of the lock tongue is not limited any more, so that a manager can disengage the lock hook from the bayonet in a mode of pressing down the lock tongue, and the lock body can be opened and taken down from the valve body.

In foretell trick lock, the trick lock box include the shell and set up the lock core in the shell, the lock core is including ability pivoted locking wheel, be provided with the executive component that can move about between locking wheel and the spring bolt, the executive component is last to have the arch, locking wheel peripheral wall can push up the executive component through the arch and lock the spring bolt, locking wheel peripheral wall is equipped with the breach that can supply protruding embedding, the executive component has the trend to locking wheel activity all the time under the effect of self elasticity or an elastic component.

The peripheral wall of the locking wheel is contacted with the bulge to push the executing piece to lock the lock tongue, so that the lock tongue cannot be operated to prevent the lock body from being opened, and the locking function is realized. When the locking wheel rotates to the breach and protruding relative time, the executive component moves to the locking wheel and makes protruding embedding breach in under the effect of self elasticity effect or elastic component, and the executive component loosens the restriction to the spring bolt to make managers can operate in order to open the lock body to the spring bolt. The coded lock adopts the same locking principle as a conventional mechanical lock, and therefore, the coded lock also has the same opening prevention performance. And the execution piece and the locking wheel are both arranged in the coded lock box and are not related to the valve, so that the coded lock can be used universally on a common valve.

In the above coded lock, the housing comprises the circular top plate and a box cover connected to the circular top plate, the executing part is a V-shaped plate, the protrusion is a sharp corner on the executing part, the lower end of the executing part is connected to the circular top plate, so that the upper end of the executing part can swing, and when the peripheral wall of the locking wheel is in contact with the protrusion, the upper end of the executing part can act on the lock tongue along the horizontal direction.

The shell includes circular roof and connects the lid on circular roof, and circular roof links firmly in the upper end of lamella body one, means that the spring bolt slides along vertical direction and sets up, so through the locate mode of above-mentioned executive component on circular roof, just so enable executive component upper end and follow the horizontal direction and act on the spring bolt when arch and locking wheel periphery wall contact to make the spring bolt can not slide downwards and make latch hook and bayonet socket throw off. The adoption is along the horizontal direction direct action on the spring bolt that sets up along vertical direction slip, can form the restriction to the spring bolt lapse down very firmly when locking to the opening nature has further been improved.

In foretell trick lock, as another kind of technical scheme, the trick lock box be fixed in the external side of the lamella body and outside the trick lock box part stretches out the lamella body, the trick lock box includes the shell and sets up the lock core in the shell, the lock core is including ability pivoted locking wheel, be provided with the executive component that can move about between locking wheel and the shell diapire, the executive component is platelike, locking structure includes the locking groove of linking firmly perpendicularly in the executive component towards the flange on the shell bottom wall face and locating the two outsides of lamella body, be equipped with the arch on the executive component face locking wheel, locking wheel peripheral wall can withstand the executive component through the arch and make the flange insert the locking inslot, the locking wheel periphery wall is equipped with the breach, be equipped with return spring between shell diapire and the executive component.

When the locking wheel is rotated to enable the protrusion to be staggered with the notch, the outer side wall of the locking wheel pushes the actuating piece to compress the return spring, so that the convex plate penetrates through the bottom wall of the shell and is inserted into the locking groove to achieve locking. When the locking wheel is rotated to enable the protrusion to be embedded into the notch, the convex plate is automatically separated from the locking groove to achieve unlocking. This scheme makes trick lock can use with ordinary valve cooperation equally.

Take valve of trick lock, include the valve body, stretch out the valve rod of valve body upper end and connect in the trick lock of valve body upper end, valve body upper end lateral part be equipped with the convex part, the trick lock includes the lock body and connects in the trick lock box on lock body surface, the lock body is upper end closed lower extreme open-ended tubular structure, valve rod and convex part all are located the lock body, its characterized in that, the lock body including can the amalgamation into above-mentioned tubular structure's petal body one and petal body two, be equipped with between petal body one and the petal body two and can be fixed mutually and receive the locking structure of trick lock box control with both, the lower extreme inboard of petal body one and/or petal body two has the fender shoulder, keeps off the shoulder and is located the convex part below.

Compared with the prior art, this trick lock and take valve of trick lock have following advantage:

1. after the coded lock is connected to the valve body, the valve rod can be well hidden to realize the locking of the valve, the defect that the valve can be opened by adopting a master key or the magnetism is weakened does not exist, and the opening prevention performance and the use reliability are well realized;

2. the valve rod is hidden outside the upper end of the valve body only through a splicing mode bag, and the coded lock cannot be directly taken down from the valve only by blocking the shoulder with the help of a structure on the valve, so that the universality of the coded lock is well improved.
