Problems solved by technology

Even if the calibration of a small threaded safety valve requires the operator to leave the center console to clamp and adjust the safety valve on the side, it brings inconvenience to the calibration operation and affects work efficiency
The clamping of the flange safety valve adopts the clamping method of three claws. This clamping method needs to be equipped with a gasket block for safety valves of different specifications (different nominal diameters), which not only increases the manufacturing cost of

Abstract

The invention relates to a safety valve check bench. A threaded safety valve check unit and a flanged safety valve check unit are respectively arranged by the left side and right side of a central console, the threaded safety valve check unit comprises a threaded base and a threaded safety valve connector, and the threaded safety valve connector is detachably mounted on the threaded base, and is used for connection with a threaded safety valve; in the flanged safety valve check unit, a sealed underpan is arranged on the top of a flanged safety valve-clamping table, and is provided with O-shaped rings which can be tightly matched with the inlet flange of a flanged safety valve for sealing; a first clamping plate and a second clamping plate are respectively arranged on both sides of the sealed underpan, and can be driven by a clamping plate-driving mechanism to transversely get close to each other or get away from each other at the same time and vertically goes up or down at the same time in order to hold the inlet flange of the flanged safety valve. The safety valve check bench is convenient to use, is more complete in functions, and can decrease the intensity of the work of operators and increase working efficiency.

Description

technical field [0001] The invention relates to safety valve calibration equipment, in particular to a safety valve calibration platform for off-line calibration of safety valves. Background technique [0002] Safety valve off-line calibration refers to removing the safety valve from the protected equipment and performing calibration at the safety valve calibration station. The safety valve calibration bench is the main equipment for off-line calibration, which is used for opening pressure adjustment and sealing performance test of safety valves. [0003] When the existing safety valve calibration platform is used to calibrate the safety valve, the threaded safety valve (referring to: the air inlet of the safety valve and the pipeline of the protected equipment adopts a threaded connection method) and the flange safety valve (referring to: the safety valve The air inlet and the pipeline of the protected equipment are connected by flange) and both use the same clamping stati...
