The system mainly includes a container, workbench with vise, cantilever jib crane, safety valve operating console, clamping bench, nitrogen cylinder group, air compressor, and air conditioner. It integrates the calibration unit, gas source, and maintenance workspace into one container for easier movement and operation.
The test bench features a separated layout with centralized control, including a DN300 safety valve clamping seat and an integrated control console. It uses hydraulic automatic clamping for medium and large safety valves and supports clean air, nitrogen, and pure water as test media. The maximum calibration pressure is 40 MPa for gas and 70 MPa for liquid, with a maximum clamping force of 275 kN.
The control console is equipped with 0.4 class precision pressure gauges for set pressure and sealing pressure judgment. To improve test accuracy and reduce pressure loss, the gas passage diameter is not less than 6 mm.
