Description

Tool for assisting valve switch

Technical Field

The utility model relates to a natural gas production and transportation gas production technology technical field, concretely relates to instrument of auxiliary valve switch.

Background

In the process of natural gas extraction and transportation, the valve needs to be opened and closed to meet the requirements of production, process, safety and the like. The valve is opened and closed by rotating the handwheel to drive the copper sleeve to rotate, so that the copper sleeve drives the valve rod to move, and the valve plate is driven by the valve rod to leave or seat in the valve seat. In the actual production process, the rotary resistance of a valve hand wheel of a part of valves is increased due to the reasons that the back pressure is large, foreign matter is blocked on the surface of the valve plate, the valve is corroded, or the valve rod is deformed, and the valves cannot be normally opened and closed without an auxiliary force application tool. Meanwhile, hand wheels of part of valves are taken back for centralized management, when inspection personnel perform opening and closing operations on the valves in the inspection process, the hand wheels and copper sleeves are different in specification due to different types of the valves, so that the hand wheels of various types need to be carried for standby, the operation is inconvenient in actual work, and the workload of the operation personnel is increased.

Currently, pipe tongs and F-type wrenches are used as auxiliary tools for these situations. When the valve is not provided with a hand wheel, the copper sleeve on the valve transmission mechanism is clamped by the pipe wrench, and the pipe wrench is pulled to rotate the copper sleeve to realize the opening and closing of the valve. In the operation process, the hardness of the copper sleeve is lower than that of the pipe tongs, so that the sleeve is abraded and bitten, and the equipment is finally damaged. When the rotation resistance of the valve hand wheel is increased, the F-shaped wrench is mainly used for increasing the torque on site, the two short cylindrical handles at the front end of the F-shaped wrench are used for clamping the edge of the valve hand wheel, and the valve hand wheel is rotated to open and close by pulling the handle, but the opening size cannot be adjusted, the contact surface with the hand wheel is small, the F-shaped wrench can slip off from the hand wheel to hurt people, and potential safety hazards exist. The valves currently in use and having relatively high switching frequency are mainly of the DN65/70, DN65/105 type, and the copper sleeves are mainly hexagonal, quadrangular and circular.
