DETAILED DESCRIPTION

[0020] The conventional locking steps of the wire lock in the related technology include: opening the lock handle and taking out the lock wire from the lock body; installing the lock buckle on the valve switch; passing the lock wire through the lock buckle and winding it around the valve body; after the lock wire is wound, pass the lock wire through the lock body; tighten the lock body to overlap the lock handle to prevent the lock wire from withdrawing; lock the main lock of the equipment to the lock body; check whether the lock buckle is fixed to the valve. If it is not firmly fixed, unlock it and continue to tighten the lock wire; confirm that the lock buckle is well fixed and the energy isolation is completed after the main lock of the equipment is installed.

[0021] However, the multiple disassembly of the lock wire and the lock body results in the defects of wasting time and manpower; the lock buckle is easily fallen off during the installation process of the valve switch, resulting in a lot of repetitive work; the lock wire is tightened by manual reinforcement, and different operators have different hand strengths, resulting in different degrees of tightening of the lock wire, and there is an unfavorable situation that the lock wire is not tightened enough, resulting in invalid energy isolation; due to the structural characteristics of the valve switch, some points of the valve have sharp edges, resulting in the wire lock not being tightened in place, posing a hidden danger of low safety factor, and the sharp edges will cause the wire lock to take too long to install.

[0022] In order to solve the above problems, a lock is disclosed. The lock is used to lock a valve. The lock comprises two movably connected covers 10 and a main lock 40. The covers 10 are movably connected to each other to form a valve. Figure 1 The locked state shown, and Figure 2 The lock is shown in the open state, and the lock can be switched between a locked state and an open state.

[0023] like Figure 1 and Figure 2 As shown, the lock of the present disclosure includes two movably connected covers 10, the first limiting hole 21a is formed by the two covers 10, and the second limiting hole 22a is formed by the two covers 10. Figure 1 and Figure 2 The two covers 10 both have a first half opening 11a on one side corresponding to the first side surface. In the locked state, the first half opening 11a of one cover 10 of the two covers 10 is close to the first half opening 11a of the other cover 10 to form a first limiting hole 21a. Figure 1 and Figure 2Both cover bodies 10 have a second half opening 12a on one side corresponding to the second side surface. In the locked state, the second half opening 12a of one of the two cover bodies 10 is close to the second half opening 12a of the other cover body 10 to form a second limiting hole 22a.

[0024] Since the first limiting hole 21a and the second limiting hole 22a are formed by being jointly enclosed by two cover bodies 10, when the lock is switched from an open state to a locked state, it is convenient for the first pipe to pass through the first limiting hole 21a, and it is convenient for the second pipe to pass through the second limiting hole 22a, thereby further facilitating the installation operation of the lock.

[0025] Figure 2 The open state of the lock is shown. In the open state, the two covers 10 are open to each other. When the valve is locked, the lock in the open state is moved to a position near the valve.

[0026] Figure 1 The locked state of the lock is shown. In the locked state, the two cover bodies 10 enclose a cover cavity 20, and a first limiting hole 21a and a second limiting hole 22a are respectively formed on the sides of the cover cavity 20. The first limiting hole 21a is located on the first side of the cover cavity 20, and the second limiting hole 22a is located on the second side of the cover cavity 20.

[0027] Regarding the valve to be locked, the valve includes a body and a plurality of pipes connected to the body, including at least one inlet pipe and one outlet pipe. In the present disclosure, it is defined that the valve includes a body and a first pipe and a second pipe connected to the body, the first pipe is connected to the third side 21 of the body, and the second pipe is connected to the fourth side 22 of the body.

[0028] When the lock is in the open state, the two cover bodies 10 are open to each other, the lock is moved to the vicinity of the valve to be locked, and then the lock is switched from the open state to the locked state, so that the valve body is smoothly placed in the cover cavity 20 of the lock, and the first pipe connected to the valve body passes through the first limiting hole 21a of the cover cavity 20, and the second pipe connected to the valve body passes through the second limiting hole 22a of the cover cavity 20, and the lock in the locked state successfully locks the valve.

[0029] In particular, for valves that achieve energy isolation, the disclosed solution is used to lock the valves that achieve energy isolation. The locking operation steps are simple, the operation is quick, and the number of operating steps is small. The defect of complex operating steps for personnel in the conventional wire lock locking method is improved. When energy isolation is required, the energy isolation work can be completed quickly, the high efficiency of energy isolation is achieved, and the safety of the operating personnel is ensured.

[0030] On the other hand, both cover bodies 10 have an opening, and the edge of the cover body 10 is provided with a first half opening 11a and a second half opening 12a which are connected to the opening, the first half openings 11a of the two cover bodies 10 correspond in position, the second half openings 12a of the two cover bodies 10 correspond in position, the two cover bodies 10 are movably connected so that the lock can switch between a locked state and an open state, and the main lock 40 is used to lock the two cover bodies, wherein, when the lock is in a locked state, the two cover bodies 10 are combined to form a cover cavity 20 for accommodating the main body, the two first half openings 11a are pieced together to form a first limiting hole 21a for the first pipe to pass through, and the two second half openings 12a are pieced together to form a second limiting hole 22a for the second pipe to pass through, the aperture of the first limiting hole 21a is smaller than the radial size of the main body along the first pipe, and the aperture of the second limiting hole 22a is smaller than the radial size of the main body along the second pipe.

[0031] In some embodiments, the cover body includes an arc-shaped plate and two end plates connected to opposite ends of the arc-shaped plate, and the two end plates are respectively provided with a first half opening and a second half opening.

[0032] In some embodiments, the arc-shaped plate and the two end plates are an integral structure.

[0033] In some embodiments, the first limiting hole and the second limiting hole are located on opposite sides of the cover cavity. Specifically, the third side 21 and the fourth side 22 of the valve body are opposite sides. Correspondingly, as shown in FIG. Figure 1 As shown, the first side surface and the second side surface are opposite sides of the housing cavity 20 .

[0034] On the other hand, if the first pipe and the second pipe of the valve are not distributed on opposite sides of the main body, the sides where the first limiting hole 21a and the second limiting hole 22a of the cover body are located also need to be adjusted accordingly to meet the functional limitation that the first pipe passes through the first limiting hole 21a of the cover cavity 20 and the second pipe passes through the second limiting hole 22a of the cover cavity 20.

[0035] In the above, the sizes of the first limiting hole 21a and the second limiting hole 22a are limited by "the aperture of the first limiting hole 21a is smaller than the size of the body along the radial direction of the first pipe, and the aperture of the second limiting hole 22a is smaller than the size of the body along the radial direction of the second pipe". Under the condition that the first limiting hole 21a allows the first pipe to pass through and the second limiting hole 22a allows the second pipe to pass through, the first limiting hole 21a is limited to not allow the third side 21 of the body to pass through, and the second limiting hole 22a is limited to not allow the fourth side 22 of the body to pass through. In some embodiments, the first side is limited to be distributed along the first direction and the second direction perpendicular to the first direction, the size of the first limiting hole 21a in the first direction is smaller than the size of the third side 21, and the size of the first limiting hole 21a in the second direction is smaller than, equal to, or greater than the size of the third side 21; the second side is limited to be distributed along the third direction and the fourth direction perpendicular to the third direction, the size of the second limiting hole 22a in the third direction is smaller than the size of the fourth side 22, and the size of the second limiting hole 22a in the fourth direction is smaller than, equal to, or greater than the size of the fourth side 22.

[0036] By limiting the dimensional relationship between the first limiting hole 21a and the third side surface 21 of the main body, and limiting the dimensional relationship between the second limiting hole 22a and the fourth side surface 22 of the main body, the side surface of the lock is designed according to the size of the valve, so that the lock can be stably mounted outside the valve, thereby improving the hidden danger of the lock moving and improving the reliability of locking the valve. After locking, the operation can be completely isolated to ensure the safety of the operators.

[0037] Regarding the movable connection of the two covers 10, in some embodiments, the two covers 10 can be rotatably connected, such as Figure 1 The rotatable connection achieved by the hinge 13 ensures that the covers 10 in the open state will not be completely separated, which facilitates the locking operation of the lock during the locking process.

[0038] In some embodiments, see Figure 1 and Figure 2 The lock includes a main lock 40 and two locking plates 30. The cover body 10 is connected to at least one locking plate 30. The locking plate 30 has a locking hole 31. In the locked state, the locking plates 30 of two adjacent cover bodies 10 are attached to each other and the locking holes 31 are opposite. The main lock 40 is detachably installed at the locking holes 31 of the two locking plates 30. Under the action of the main lock 40, the locking plates 30 will not separate, thereby fixing the cover bodies 10 together, so that the lock of the present disclosure is maintained in a locked state.

[0039] In some embodiments, please refer to Figure 1 and Figure 2 The lock comprises two movably connected cover bodies 10, both of which are semi-cylindrical, so that the cover cavity 20 of the lock is cylindrical in the locked state.

[0040] In some embodiments, the cover body 10 is made of 304 stainless steel, which has a rust-proof function and improves the service life of the lock of the present disclosure.

[0041] In some embodiments, the thickness of the cover body 10 is 2 mm±0.5 mm, which meets the use requirements of the lock of the present disclosure.
