Abstract

The invention belongs to the technical field of safety valve inspection, and discloses a clamping mechanism for inspecting a safety valve. The clamping mechanism comprises a clamping mechanism covering the lower side of a protective cover, the clamping mechanism comprises a safety valve sealing bottom plate arranged in the center of a workbench, a plurality of sliding grooves are formed in the periphery of the safety valve sealing bottom plate, clamping jaws are arranged in the sliding grooves, connecting rods are arranged on the lower portions of the clamping jaws, the connecting rods are connected with a rotary disc, a rotary disc handle is arranged on the rotary disc, and the clamping jaws slide along the sliding grooves when the rotary disc handle rotates. The beneficial effects of theclamping mechanism are that: the clamping jaws capable of moving along the sliding grooves are arranged in the sliding grooves at the bottom portion to effectively adjust the distance between the clamping jaws and the safety valve sealing bottom plate arranged at the center of the workbench, and pressing plates penetrating through the upper portions of the clamping jaws can be fixed on the flanges of the safety valves when the safety valves are clamped, and the safety valves can be clamped in the transverse and longitudinal angles by pushing an oil cylinder at the bottom portion; and moreover, the clamping mechanism is simple, easy to adjust and suitable for valves of various specifications.

Description

technical field [0001] The invention generally relates to the technical field of safety valve inspection, in particular to a clamping mechanism for inspecting safety valves. Background technique [0002] In the field of safety valve pressure inspection, setting up an easy-to-use clamping mechanism has always been a concern of all parties; the structure of the existing clamping mechanism for testing the pressure of the safety valve is relatively complicated, and it cannot realize the simultaneous adjustment of multiple jaws. And it can only realize the clamping of the safety valve to be tested in one direction. When performing 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, there is a problem that it is inconvenient to move because the clamping mechanism of the safety valve is ...
