Abstract

The invention provides a valve wrench. The valve wrench comprises a wrench body and working portions. The working portions include a first working portion and a second working portion. The first working portion and the second working portion are arranged on the wrench body, and the separation distance between the first working portion and the second working portion can be adjusted. The first working portion is fixed to the wrench body, and the second working portion is movably arranged on the wrench body. The wrench body comprises a plate body and a sliding groove. The sliding groove is formedin the plate body. The second working portion is partially arranged in the sliding groove. The second working portion comprises a working rod, a threaded rod and a nut. The threaded rod is arranged at the first end of the working rod, the diameter of the threaded rod is smaller than the width of the sliding groove, the diameter of the first end of the working rod is larger than the width of the sliding groove, and the external diameter of the nut is larger than the width of the sliding groove. By the adoption of the technical scheme, the problem that in the prior art, the distance between working portions of a valve wrench cannot be adjusted is effectively solved.

Description

technical field [0001] The invention relates to the technical field of removal tools, in particular to a valve wrench. Background technique [0002] In the construction of pipeline engineering, many valves will be set on the pipeline. These valves need to be opened or closed frequently. Some pipelines are under high pressure and the valves are tightly sealed. Only a wrench can be used to open or close the valves. Specifically, the valves It has a hand wheel, the hand wheel includes a circular outer ring and a spoke valve wrench fixed to the outer ring. The working part of the valve wrench is two spaced working rods. Hand wheel to open and close the valve. However, the distance between the two working rods of the existing valve wrench with two working rods is not adjustable, and can only be matched with a handwheel of one size. When the staff inspects the pipeline, they must carry multiple Valve wrench, very inconvenient. Contents of the invention [0003] The main purpo...
