Valve static pressure life automatic test device based on gasification booster

Abstract

The invention relates to the technical field of valve static pressure life testing, in particular to an automatic valve static pressure life testing device based on gasification boosting, which can be applied to control valves such as ball valves, gate valves, butterfly valves, and globe valves. The device includes a control system, Gas source pressurization system, loading system and drive system. The present invention uses the gas source pressurization system to provide high-pressure gas, thereby simulating the opening and closing of the tested valve under different medium pressure conditions, and the detection component monitors the operation of the tested valve in real time. Position, upstream and downstream pressure information, etc., can evaluate the opening and closing cycle state and sealing performance of the tested valve, improve the accuracy of the test, and the loading system controls the loading and unloading of high-pressure gas passing through the tested valve, so as to realize According to the technical requirements of the static pressure life test standard of the control valve, the static pressure life test of the valve can be automatically completed, and the high-pressure gas consumption during the test can be reduced, which has the advantage of being green and low cost.

Description

technical field [0001] The invention relates to the technical field of valve static pressure life testing, in particular to an automatic valve static pressure life testing device based on gasification boosting, which is applicable to control valves such as ball valves, gate valves, butterfly valves, and globe valves. Background technique [0002] Control valves represented by ball valves, gate valves, butterfly valves, and globe valves are common control elements in the process industry. my country is a big country in the process industry. With the construction of large-scale domestic projects such as large-scale coal chemical industry, super-large-capacity generator sets, and new energy projects, the importance of valve static pressure life parameters has become increasingly prominent, and it has become a factor related to the operation of the entire production line using control valves. An important evaluation index of reliability, economy and safety. Carrying out the stat...
