Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a valve switching tool. Background Art

[0002] In the daily operations of offshore oil and gas production facilities, valve operation is a frequent and crucial task, covering various types and sizes of ball valves, gate valves, globe valves, and butterfly valves. These valves are often difficult to switch on and off due to large size differences, aging caused by long-term exposure to harsh environments, or different switching frequencies. Traditionally, for handwheel switch type valves, operators have to rely on a series of F wrenches of different sizes for assistance. This not only requires the platform to stock a large number of F wrenches to meet different needs, but also results in significant material waste and financial expenditure. What is even more troublesome is that in emergency or daily operations, work progress is frequently delayed due to the inability to quickly find an F wrench of the matching size, which seriously affects work efficiency and production safety.

[0003] On the other hand, for handle-operated ball valves and butterfly valves, the traditional approach is to use steel pipes of varying lengths for auxiliary operation, but this approach also faces numerous challenges. First, the diverse specifications of the steel pipes complicate inventory management. Second, in actual operation, finding the right steel pipe length is often time-consuming and labor-intensive, which again becomes a bottleneck restricting work efficiency. In summary, traditional valve auxiliary opening and closing methods are insufficient in offshore oil and gas production environments, and a more efficient, flexible, and economical solution is urgently needed.

[0030] The length of the screw 2 is adjustable, and the jaws 1 are arranged at the front end of the screw 2;

[0031] The jaws 1 include a first caliper 11 and a second caliper 12 connected to the same plane. The distance between the two calipers is suitable for hand wheels of switch valves of different sizes.

[0032] In this embodiment, the valve switching tool includes a jaw 1 and a screw 2. The screw 2 serves as the main structure, and its length can be adjusted according to actual needs to adapt to the operating space requirements under different working environments. The front end of the screw 2, that is, the end away from the operating handle, is fixed with the jaw 1 by a sturdy connection. The jaw 1 includes a first caliper 11 and a second caliper 12; the two calipers are tightly connected in the same plane to form a stable clamping structure. The distance between the two calipers is not fixed, but can be flexibly adjusted through a specific adjustment mechanism to match and firmly clamp valve handwheels of various sizes. The jaw 1 is suitable for fixing valve handwheels of various types and sizes of handwheel switches such as ball valves, gate valves, stop valves, etc., and is used for auxiliary switching work of such valves.

[0033] The valve opening and closing tool provided by this utility model, with its unique jaw and screw combination design, significantly improves the efficiency and convenience of on-site operations at offshore oil and gas production facilities. The wide applicability of the jaws enables it to easily handle valve handwheels of various types and sizes of ball valves, gate valves, globe valves, and other valves, achieving standardization and universalization of valve auxiliary opening and closing operations. The adjustable screw length further enhances the tool's flexibility and ensures effective use in different operating spaces. With this tool, operators can complete valve opening and closing operations with greater ease, not only reducing the workload but also improving the safety and efficiency of operations, which is of great significance for ensuring the smooth operation of offshore oil and gas production facilities.

[0034] According to one embodiment of the present invention, the two calipers are distributed and fixed on the same plane of the screw 2, and there is an angle between the two calipers.

[0035] In this embodiment, the first caliper 11 and the second caliper 12 are both welded to the screw 2, and the two calipers are located in the same plane. There is an angle between the two calipers. The distance between the two calipers is the smallest near the connection of the screw 2, and the distance between the two calipers gradually increases away from the direction of the screw 2. The two calipers are welded to the front end of the screw and are used to fix the handwheel for switching the valve.

[0036] The utility model effectively improves the adaptability of the valve switching tool to handwheels of different shapes and sizes by welding two calipers with an included angle to the front end of the screw, thereby enhancing the flexibility and convenience of operation.

[0037] Figure 2 This is a schematic diagram of the screw front end structure of an embodiment of the present invention. Figure 2 As shown, according to an embodiment of the present invention, two calipers are connected in parallel to the same plane of the screw 2, the first caliper 11 is fixedly connected to the screw 2, and the distance between the second caliper 12 and the first caliper 11 is adjustable.

[0038] Preferably, a movable groove 21 and multiple slots 22 are provided on the screw 2, and a block 13 is provided at one end of the second caliper 12. The second caliper 12 can be adjusted in the movable groove 21 according to the size of the handwheel for switching the valve, and the block 13 matches the size of the slot 22.

[0039] In this embodiment, the first caliper 11 and the second caliper 12 are connected parallel to the same plane of the screw 2, forming a stable and flexible clamping structure. The first caliper 11 is tightly bonded to the screw 2 through welding, ensuring the stability of the overall structure. The second caliper 12 maintains an adjustable distance from the first caliper 11, allowing the tool to accommodate valve handwheels of different sizes.

[0040] To adjust the spacing, a movable slot 21 is provided on screw 2, providing space for the second caliper 12 to move. Screw 2 also features multiple locking slots 22, which match the dimensions of the clamping blocks 13 at one end of the second caliper 12. To adjust the caliper spacing, the user slides the second caliper 12 along the movable slot 21 to the appropriate position. The clamping blocks 13 then lock into the corresponding slots 22, precisely fixing the spacing.

[0041] This embodiment adopts a parallel-connected adjustable caliper design, combined with the movable groove and clamping groove structure on the screw, which not only ensures the stability and accuracy of the valve switching tool when clamping handwheels of different sizes, but also greatly improves the flexibility and applicability of the tool. Users can easily handle valve switching work of various specifications without changing tools, thereby improving work efficiency and reducing operating costs.
