Technical Field

[0001] The utility model relates to the technical field of valve locks, in particular to a novel valve lock. Background Art

[0002] As various pipelines are produced, various valves are also produced to serve all walks of life and bring convenience to managers and users. Valves have more and more uses. Some valves need to be opened for use and closed when there is a fault, which is very convenient; some valves need to be closed because the subsequent work has not been completed or they cannot be opened in the near future. Opening them will cause certain economic losses. At this time, if a valve with magnets and locks is installed, the cost is too high, and the price is several times that of an ordinary valve. The cost budget is too high, and it is not easy for users to accept it. Utility Model Content

[0013] Preferably, an elastic pad is fixed to the inner wall of the steel pipe, and a moisture-proof pad is fixed to the inner wall of the elastic pad.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] (1) By putting the steel pipe on the valve shaft, the iron chain goes down from one side, passes around the pipe and comes up from the other side, and then locks it with an ordinary lock and another lug, the valve shaft can be blocked to prevent the valve shaft from being operated by mistake. There is no need to install a high-cost magnetic or lock valve, the overall cost is low and it is easy to use.

[0016] (2) By setting a limit stopper, when the valve lock is not needed, the iron chain can be wrapped around the outside of the steel pipe, and then the stop rod can be passed through the second convex strip with a perforation, and the bottom end of the stop rod can be screwed into the threaded hole to block the iron chain and prevent it from spreading.

[0017] (3) After the steel pipe is put on the valve shaft, the moisture-proof pad is put on the outer periphery of the valve shaft, which can effectively prevent moisture and reduce the occurrence of rust. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figures 1-4 As shown, the utility model provides a new valve lock, including a steel pipe 1 and an iron chain 3. Two lugs 2 are symmetrically welded at one end of the outer wall of the steel pipe 1, and the end of the steel pipe 1 close to the lug 2 can be sleeved on the valve shaft, one end of the iron chain 3 is connected to one lug 2, and the iron chain 3 can be connected to the other lug 2 through an ordinary lock, and a cross-shaped sealing strip 4 is welded at the end of the steel pipe 1 away from the lug 2.

[0026] The valve lock can be used on various steering wheel valves. When used, just remove the steering wheel of the valve and use it on valves of DN50-DN1000 or even larger. Its method is very simple. Use a 15 cm long, DN50 steel pipe 1, weld one end to seal the cross-shaped sealing strip 4 or other configuration sealing strip for sealing, and the sealing strip can be welded with steel bars, and two lugs 2 are symmetrically welded on both sides of the other end. According to the size of the valve, a certain length of iron chain 3 is selected and fixed to the lug 2 on one side. Remove the steering wheel of the valve, put the DN50 steel pipe 1 on the valve shaft, and the iron chain 3 goes down from one side, bypasses the pipe and comes up from the other side. Then use an ordinary lock to lock it with the other lug 2 to block the valve shaft and prevent the valve shaft from being operated by mistake.

[0027] In addition, the novel valve lock further comprises a position-limiting blocker, which is used to limit the spreading of the iron chain 3 after being wound around the outside of the steel pipe 1 when the iron chain 3 is not in use.

[0028] Among them, see Figure 1-Figure 3 As shown, the position limiting blocking member includes a second ridge 6 and a first ridge 5 welded to the outer wall of the steel pipe 1, the second ridge 6 is penetrated by a blocking rod 7, and the second ridge 6 is provided with a through hole 10 for the blocking rod 7 to pass through, the bottom end of the blocking rod 7 is detachably connected to the first ridge 5, the first ridge 5 is provided with a threaded hole 11, and the lower end of the outer wall of the blocking rod 7 is provided with an external thread 12.

[0029] Through the above, when the valve lock is not needed, the iron chain 3 can be wrapped around the outside of the steel pipe 1, and then the blocking rod 7 can be passed through the second ridge 6 with the through hole 10, and the bottom end of the blocking rod 7 can be screwed into the threaded hole 11 to block the iron chain 3 and prevent the iron chain 3 from spreading.

[0030] Furthermore, a screw block 13 is fixed to the top end of the blocking rod 7 , and a plurality of protruding rods 14 are provided on the outer wall of the screw block 13 .

[0031] Specifically, the twist block 13 provided with the protruding rod 14 is used to facilitate the rotation of the blocking lever 7, which is beneficial to the application of force by the hand and is more convenient.

[0032] Also, see Figure 2 As shown, an elastic pad 8 is fixed to the inner wall of the steel pipe 1 , and a moisture-proof pad 9 is fixed to the inner wall of the elastic pad 8 .

[0033] Through the above, after the steel pipe 1 is sleeved on the valve shaft, the moisture-proof pad 9 is sleeved on the periphery of the valve shaft, which can effectively prevent moisture and reduce the occurrence of rust. The elastic pad 8 has a certain elasticity and can achieve extrusion deformation for valve shafts of different diameters.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
