Abstract

The invention belongs to the technical field of safety valve inspection, and discloses a compatible safety valve pressure testing device and method. The device comprises a clamping system, a hydraulicsystem, an air pressure system for supplying air to a safety valve and a water pressure system for supplying water to the safety valve. The clamping system comprises a rotating disc which is arrangedon the workbench and provided with a hole in the center, a plurality of sliding grooves are symmetrically formed in the workbench, and the clamping jaws are arranged in the sliding grooves in a sleeved mode through sliding rails. A pressing plate is arranged at the upper part of the clamping jaw, one end of the connecting rod is connected with the lower part of the clamping jaw, and the other endis connected with the rotating disc; the upper end of the support pillar is connected with a safety valve sealing bottom plate for placing a safety valve, and the lower end of the support pillar is connected with the oil cylinder; the oil cylinder is connected with the hydraulic system; sealing grooves matched with safety valves of different specifications are formed in the safety valve sealing bottom plate, and the safety valves are clamped between the safety valve sealing bottom plate and the clamping jaws or the pressing plates. The invention has the beneficial effects that the clamping device is simple, easy to adjust and suitable for valves of various specifications.

Description

Technical field [0001] The present invention generally relates to the technical field of safety valve inspection, in particular to a compatible safety valve pressure inspection device and method. Background technique [0002] In the field of safety valve pressure inspection, setting up an easy-to-use clamping system has always been a concern of all parties; the existing clamping system for checking safety valve pressure has a complicated structure and cannot realize the simultaneous adjustment of multiple clamping jaws. And it can only realize the clamping of the safety valve under test in one direction. During the clamping operation, more complicated operations are required to realize the clamping of the safety valve, and the clamping effect is not good, which cannot meet the inspection of various types of safety valves. ; When realizing on-site clamping, because the safety valve clamping system is too heavy, there is a problem of inconvenience to move. Summary of the invention...
