Description

Technical Field

[0001] This utility model relates to the field of valve switch safety technology, and in particular to a valve locking safety cover device. Background Technology

[0002] Currently, most steel plant hydraulic station valves are opened and closed using handles. During on-site maintenance, workers sometimes accidentally open valves using the handles, potentially causing equipment malfunctions and posing a safety risk, which does not comply with safety management regulations. To address this issue, on-site personnel often close the valves first and then attach a safety rope and padlock to the valve outlet. However, with numerous maintenance workers on-site, they sometimes accidentally operate the handles to open or close the valves, creating serious safety hazards. Utility Model Content

[0003] To solve the above technical problems, this utility model provides a valve locking safety cover device, which can cover the valve switch and lock the valve switch with the help of a pin. It can effectively prevent the operator from accidentally opening the valve by the handle, avoid misoperation, and eliminate safety hazards.

[0004] The valve locking safety cover device in this solution includes a cylindrical body with at least one open end and an internal accommodating space. The cylindrical body has a through hole, and a pin is adapted to be inserted into the through hole. One end of the pin is provided with a positioning step, and the other end has a through hole, so that when the end of the pin with the through hole passes through the opening of the cylindrical body, the positioning step of the pin abuts against the outer wall of the cylindrical body, and the through hole of the pin extends out of the outer wall of the other end of the cylindrical body.

[0005] The further defined technical solution of this utility model is:

[0006] Furthermore, the cylindrical body is a cylindrical structure with one end open.

[0007] Furthermore, the outer diameter of the cylindrical shape is 70 mm and the length is 75 mm.

[0008] Furthermore, the positioning step is a disc-shaped structure, and the cross-sectional diameter of the positioning step is larger than the diameter of the opening.

[0009] Furthermore, it also includes a lock that fits and engages within the through hole.

[0010] The beneficial effects of this utility model are as follows: The valve locking safety cover device provided by this utility model can cover the valve switch as a whole and lock the valve switch with the help of the pin. It can effectively prevent the operator from accidentally opening the valve through the handle, avoid misoperation, eliminate safety hazards, improve the safety of the valve of the hydraulic station valve platform, and the device has a simple structure and is easy to use.

[0014] This embodiment provides a valve locking safety cover device, such as... Figure 1 As shown, the device includes a cylindrical body 10 with an open end and an internal accommodating space. Specifically, the cylindrical body 10 is cylindrical and has an opening 11 through it. A pin 20 is inserted into the opening 11. One end of the pin 20 is provided with a disc-shaped positioning step 21. The diameter of the positioning step 21 is larger than the diameter of the opening 11. The other end of the pin 20 has a through hole 22. When the end of the pin 20 with the through hole 22 passes through the opening 11 of the cylindrical body 10, the positioning step 21 of the pin 20 abuts against the outer wall of the cylindrical body 10, and at this time, the through hole 22 of the pin 20 can extend out of the outer wall of the other end of the cylindrical body 10.

[0015] like Figure 2 The diagram shown is a schematic of the valve locking safety cover device in use according to this utility model. The hydraulic system 30 has a valve switch 31, and a valve lock hole 32 passes through the valve switch 31 (see...). Figure 1 Generally, when starting or closing the entire hydraulic system 30, the starter handle (not shown in the figure) needs to be inserted into the valve lock hole 32 of the valve switch 31. At this time, the entire valve switch 31 can be rotated to control the opening or closing of the hydraulic system 30. When the starter handle is pulled out, the valve switch 31 is locked in place. See also... Figure 2 When the valve locking safety cover device of this utility model is used, the cylindrical body 10 is placed over the outside of the valve switch 31, and the pin 20 is inserted and passes through the opening 11 and the valve lock hole 32. Since the pin 20 passes through the valve lock hole 32, and is not an operating handle that is adapted to the valve lock hole 32, the valve switch 31 is still locked and cannot be turned by others. Then, the lock 40 is used to lock the through hole 22 at the other end of the pin 20, which can lock the cylindrical body 10 and the valve switch 31, prevent other personnel from operating it by mistake, and eliminate safety hazards.

[0016] In addition to the above embodiments, this utility model may have other implementation methods; all technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
