Description

Hydraulic valve leakage and pressure-resistant detection equipment Technical Field The utility model relates to the technical field of hydraulic valve detection, in particular to a hydraulic valve leakage and pressure resistance detection device. Background The hydraulic valve is an element for controlling the flowing direction, pressure and flow of oil in the hydraulic system, plays a vital role in the hydraulic system, and can be subjected to tightness and pressure resistance detection after production, the tightness detection is used for preventing the oil leakage of the hydraulic valve in the working process, once the oil leakage occurs, the oil leakage is wasted, the pressure of the system is reduced, the action of an actuating element is misaligned, the working environment is polluted, and safety accidents are caused. The pressure-proof detection is used for checking the structural strength and sealing performance of the hydraulic valve under the maximum working pressure set by the system and even higher pressure, so that the problems of cracking, deformation and the like of the hydraulic valve under extreme working conditions are avoided, and the long-term stable and reliable operation of the hydraulic system is ensured.
