[0025] The embodiments of the present application will be further described below with reference to the drawings: As Figures 1-3 shown, a kind of auxiliary tool for various valve wheel switch, including screw rod 2, screw rod 2 includes horizontal rod 2-1 and vertical rod 2-2, horizontal rod 2-1 with vertical rod 2-2 "L" shape setting, vertical rod 2-2 side movably provided with detachable jaw 1, detachable jaw 1 is arranged in parallel with horizontal rod 2-1, the length of detachable jaw after installation 1 with the length of horizontal rod 2-1 consistent, screw rod 2 with detachable jaw 1 "F" shape setting, vertical rod 2-2 bottom movably provided with detachable force rod 3.

[0026] Specifically, detachable jaw 1, screw rod 2, detachable force rod 3 jointly constitute the moment transmission assembly for driving valve wheel rotation. By jaw clamping valve wheel, by the moment transmission of screw rod 2 and detachable force rod 3, drive valve wheel rotation, realize valve switch operation. Detachable jaw 1, screw rod 2 and detachable force rod 3 are all explosion-proof materials. Preferably, the explosion-proof material provided in the embodiment is explosion-proof copper alloy or explosion-proof stainless steel, which meets the safety requirements of special operating environment of certain offshore platform.

[0027] As Figure 2As shown, the detachable jaw 1 provided in this embodiment is a cylinder. One end of the detachable jaw 1 is provided with a first external thread 1-1, and the side wall of the vertical rod 2-2 is provided with a plurality of first threaded holes 2-3. The plurality of first threaded holes 2-3 are distributed in a straight line. The first external thread 1-1 cooperates with any of the first threaded holes 2-3 to realize the jaw size adjustment of the detachable jaw 1 and the screw 2. Preferably, the detachable jaw 1 is provided with various specifications, all of which can be adapted to the same screw 2 for clamping the disc of a gate valve, globe valve, ball valve, butterfly valve or check valve.

[0029] The screw 2 is designed with an adjustable length structure. By adjusting its own length, the overall torque of the torque transmission component can be changed. For shut-off valves that are difficult to open under high pressure conditions and butterfly valve discs that become stuck after long-term use, the operating torque can be increased by extending the length of the screw 2 to ensure smooth valve opening and closing. The bottom of the tail end of the screw 2 is machined with internal threads for connection with the detachable force-adding rod 3.
