Description

Technical Field

[0001] The utility model belongs to the field of safety valve detection auxiliary equipment, in particular to a jump-assist wrench auxiliary opening device for safety valve detection. Background Art

[0002] Safety valves are commonly used safety devices in pressure pipes or containers. They automatically open to relieve pressure when the internal pressure reaches a threshold. Safety valves also come with a trip wrench. This trip wrench's primary function is to manually release pressure when the pressure in the pipe or container exceeds the threshold, but the safety valve becomes stuck or otherwise fails to open automatically. Therefore, the reliability of the trip wrench also requires regular testing.

[0003] When testing the reliability of jump wrenches in existing factories, they are all manually turned by hand. Some pipelines contain not only high-pressure gas, but also high-temperature and high-pressure steam. If the jump wrenches are turned directly by hand, the ejected high-pressure gas will pose a safety hazard and may cause injury to the workers. Utility Model Content
