Description

Technical Field

[0001] This utility model relates to the field of valve opening and closing tools, and in particular to a concealed valve opening and closing device. Background Technology

[0002] In existing technologies, concealed valves are often installed in gas pipeline systems to prevent unauthorized operations and protect against environmental influences. A common feature of these valves is that there is a height difference between the valve position and the worker's normal standing position, which leads to problems such as inconvenience in opening and closing the valve and lack of safety in opening and closing.

[0003] Specifically, on the one hand, due to the height difference, existing valve opening and closing tools mostly use F-type wrenches with extension rods. The lack of effective position recognition and locking between the wrench and handwheel makes it difficult to apply force effectively and turn the valve inconveniently. On the other hand, when operating such tools, the operator's limbs are mostly positioned directly above the valve, which contradicts the actual safety control procedure and makes opening and closing unsafe. These problems result in low efficiency in emergency repairs and routine maintenance, and make it even more difficult to guarantee personnel safety in the event of accidents.

[0004] There is currently no corresponding solution to the above problems. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a concealed valve opening and closing device with a simple structure, based on the quick identification of the valve stem, fast and effective turning, and especially safer operation with personnel located on the side of the valve during the opening and closing process.

[0006] The equipment includes valve reclaiming wrenches and tightening wrenches; The valve retrieval wrench includes a connecting rod, the effect of which is to retrieve the lower component of the valve based on its length; The lower part of the connecting rod is provided with a U-shaped connecting frame, and a valve reclaiming component is provided on the bottom surface of the U-shaped connecting frame; The valve claiming component includes a claiming sleeve centrally located; extension rods are integrally connected to both sides of the outside of the claiming sleeve, and the two extension rods are connected to a U-shaped connecting frame. A valve actuating lever is slidably mounted on each of the two extension rods; A base is integrally connected to the connecting rod, and a rotating rib is integrally connected to the base. The wrench includes a force-applying rod connecting part and a prism sleeve recognizing part; the force-applying rod connecting part and the prism sleeve recognizing part are integrally connected, and the prism sleeve recognizing part has a groove inside that fits the outside of the prism sleeve.

[0007] The effect achieved in this way is as shown in the attached diagram of the instruction manual. Figure 1As shown, the valve stem part of the valve claiming sleeve is used to claim the valve. Its valve actuating rod is inserted into the valve gap to form a claiming assembly, thereby realizing the quick claiming of the valve claiming wrench and the valve. When the turning wrench is put into its turning rib sleeve, based on the setting of its force-adding rod connection part and the cooperation form of the two, the operator is naturally positioned on the side of the valve, avoiding the valve flying out and accidentally injuring people.

[0008] The beneficial effects of this utility model are: it solves the problem of inconvenient opening and closing of concealed valves in gas pipelines in the prior art, and is especially suitable for valves where there is a height difference between the valve and the worker's standing surface. Its structure is simple, quick to adopt, and safe to use; that is, during use, the worker is naturally positioned to the side of the valve, which can avoid accidental injury.

Detailed Implementation

[0010] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The concealed valve opening and closing device of this utility model includes a valve claiming wrench 2 and a turning wrench 1; The valve retrieval wrench 2 includes a connecting rod 23, which has the effect of retrieval of its lower component to the valve based on its length; A U-shaped connecting frame 24 is provided at the lower part of the connecting rod 23, and a valve claiming component is provided on the bottom surface of the U-shaped connecting frame 24; The valve claiming component includes a claiming sleeve 25 centrally located; on the outside of the claiming sleeve 25, extension rods 26 are integrally connected to both sides, and the two extension rods 26 are connected to the U-shaped connecting frame 24. A valve actuating rod 27 is slidably mounted on each of the two extension rods 26; A base 22 is integrally connected to the connecting rod 23, and a rotating prism sleeve 21 is integrally connected to the base 22. The wrench 1 includes a force-adding rod connecting part 11 and a prism sleeve recognizing part 12; the force-adding rod connecting part 11 and the prism sleeve recognizing part 12 are integrally connected, and the prism sleeve recognizing part 12 has a groove inside that fits the outside of the prism sleeve 21.

[0011] The effect achieved in this way is as shown in the attached diagram of the instruction manual. Figure 1 As shown, the valve stem portion of the valve is claimed by the claim sleeve 25, and the valve actuating rod 27 is inserted into the valve gap to form a claim assembly, thereby realizing the quick claim of the valve claim wrench 2 and the valve; the turning wrench 1 is put into its turning rib 21, and based on the setting of its force-adding rod connection part 11 and the cooperation form of the two, the operator is naturally positioned on the side of the valve, avoiding the valve flying out and accidentally injuring people.

[0012] In Example 1, the connecting rod 23 is a tubular structure, including an inner sleeve and an outer sleeve; a rigid limiting bolt or spring pin is provided between the inner sleeve and the outer sleeve.

[0013] This controls the length of the connecting rod 23, allowing it to accommodate more height differences between standing surfaces and concealed valves.

[0014] In Example 2, the connecting rod 23 is integrally connected to the U-shaped connecting frame 24, and the U-shaped connecting frame 24 is integrally connected to the valve reclaiming component.

[0015] This optimizes the configuration structure, enabling rapid adjustment and deployment.

[0016] In Example 3, the claim sleeve 25 is in the form of a conical cylinder, that is, its inner cavity gradually decreases from bottom to top.

[0017] The effect achieved in this way is based on the large diameter of its bottom surface to quickly identify the valve stem, and on the small diameter of its top surface to achieve a fitting and positioning effect on the valve.

[0018] In Example 4, the extension rod 26 is a square tube or a spline rod, and the upper part of the valve actuating rod 27 is provided with a sliding sleeve, which is slidably mounted on the extension rod 26 based on the sliding sleeve. The sliding sleeve is also provided with a hard limit bolt or a spring pin; when the sliding sleeve is provided with a spring pin, the extension rod 26 is also provided with a pin hole.

[0019] This allows for the adjustment of the distance between the two valve actuation levers 27, making them compatible with the valves.

[0020] In Example 5, the base 22 is a disc with a diameter larger than that of the rotating prism 21.

[0021] This facilitates the positioning or limiting of the aforementioned wrench 1, making it easier to apply force.

[0022] Furthermore, the screw-on sleeve 21 is an external hexagonal cylinder, and its height is set to be more than twice the thickness of the screw-on wrench 1.

[0023] The effect achieved is shown in the attached diagram in the instruction manual. Figure 1 As shown, the higher turning sleeve 21 can effectively prevent the turning wrench 1 from coming off during the turning process.
