Abstract

The invention belongs to the technical field of valve detection, and relates to a valve detection method. A to-be-detected valve is clamped by a valve clamping device on a clamping table, the method comprises the adjustment of the clamping force of the to-be-detected valve, and the method comprises the following steps of: weighing the to-be-detected valve to obtain the gravity G of the valve; calculating the adjusting force F=P*S corresponding to the setting pressure according to the flow channel sectional area S of the valve and the setting pressure P; and calculating the clamping force according to the valve gravity G, the adjusting force F and the sealing coefficient K; the invention further provides valve detection equipment, the detection equipment comprises a clamping table and a valve clamping device arranged on the clamping table, the clamping table comprises a clamping frame and a fixing plate arranged on the clamping frame, and the valve clamping device comprises a clamp arranged on the fixing plate and a driving device for applying and adjusting clamping force. According to the valve detection method and detection equipment provided by the invention, the clamping force can be adjusted for valves of different specifications.

Description

technical field [0001] The invention belongs to the technical field of valve detection, and relates to a valve detection method and detection equipment. Background technique [0002] After the safety valve is assembled, it is necessary to test and verify the opening pressure value and sealing performance of the valve. The above tests are completed by valve testing equipment, and a clamping device is required to clamp the valve to be tested during the test. Since the valves have different specifications, the clamping force required for the valves of different specifications is not the same. When the clamping force is too small, the valve to be tested will loosen during the test, which will affect the accuracy of the test and the smooth progress of the test; when the clamping force is too large, the valve will be easily damaged. [0003] Chinese invention patent application CN 108195515 A discloses a valve testing machine, which includes a test bench and a control system. R...
