Safety valve performance online detection device

Abstract

The invention provides a safety valve performance online detection device. The safety valve performance online detection device comprises an operation piano-type cabinet and a mechanical operation platform; the operation piano-type cabinet is provided with a display, a keyboard, a mouse and a power source switch; an electrical control system is arranged in the operation piano-type cabinet; the electrical control system comprises a host computer as well as a PLC and an NI data acquisition card which are both electrically connected with the host computer; the electrical control system further comprises a switching quantity unit, a pressure regulating valve, an inlet pressure sensor and an outlet pressure sensor which are all electrically connected with the PLC; and the electrical control system also comprises an electronic scale, a test pressure sensor, a temperature sensor, a displacement sensor and a flow sensor which are all electrically connected with the NI data acquisition card. With the safety valve performance online detection device of the invention adopted, various kinds of performance parameters of safety valves can be detected precisely and automatically.

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...

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
