Description

Technical Field

[0001] The utility model relates to the technical field of hand tools, in particular to a wrench for valves on underground buried pipelines. Background Art

[0002] At present, the opening and closing of valves installed on pipelines are usually done by construction workers holding the valve handle and applying force to open and close the valve. This method can achieve normal valve opening and closing for small valves on pipelines above the ground. However, for valves on pipelines below the ground (i.e., underground pipelines), construction workers usually need to bend down and kneel on the ground to reach out to the valve handle and apply force to turn the valve to open and close it. For valves on deeply buried pipelines, construction workers cannot turn the valve handle by hand. Therefore, for underground pipelines, the process of opening and closing the valve is time-consuming and laborious. Moreover, when the valve needs to be opened and closed urgently, the construction workers cannot open and close the valve quickly, which may lead to related safety accidents. Utility Model Content
