Problems solved by technology

[0005] The above two patents only test the pressure performance of the safety valve alone, and the criteria for judging whether the safety valve is qualified, safe, and which working environments can be applied need to be determined by multiple performance parameters, so it is not important to carry out the test. Comprehensively, the present invention proposes a reasonable detection scheme for the existing problems, and conducts automatic online detection of multiple performances of safety valves

Description

technical field [0001] The invention belongs to the technical field of safety valve performance detection, and in particular relates to a safety valve performance detection device. Background technique [0002] Safety valve is a kind of valve with protective function. With the development of various industries, the varieties and specifications of safety valves are also increasing. There are more and more industries using safety valves, such as petrochemical industry, oil refining industry, nuclear power industry, The thermal power industry is widely used, so the quality of safety valves and product performance must meet very high standards. In the process of producing high-parameter safety valves, it is necessary to continuously monitor the performance of safety valves online. The current market Most of the safety valve test devices are manually controlled to adjust the pressure, and there is no good method for low flow detection of liquid water as the medium, and the test i...
