Problems solved by technology
[0002] Proportional valve is a valve body commonly used in gas systems. It is very common. After the proportional valve is manufactured, it needs to be tested for its sealing and other performance. The existing proportional valve generally includes two or more sections. The sealing test of the whole body and each section is generally carried out manually, the efficiency is low, and the labor cost is high. Therefore, the present invention provides an automatic detection device for the sealing performance of proportional valves to solve the above problems

The invention discloses a detection device for sealing performance of a proportional valve. The detection device comprises a pressure regulating device, a leak detection device, a test interface and an outlet valve which are connected in series sequentially, wherein the test interface is connected with a bypass valve in parallel; the input end of the pressure regulating device is communicated witha high-pressure gas source and the pressure regulating device is used for regulating output gas pressure to a set value; the test interface comprises an inlet and an outlet which are connected with the input end and the output end of a to-be-detected valve respectively; the outlet valve can be opened or closed; the leak detection device is used for performing leak detection on the to-be-detectedvalve. With the adoption of the structure, after the detection device is connected with the high-pressure gas source and the to-be-detected valve, different pressure is output by means of the pressureregulating device, the sealing performance of the to-be-detected value is tested under different pressure, overall sealing performance and partial sealing performance of the proportional valve can bedetected automatically under matching of opening-closing of the valve body and the bypass valve, and the automation degree and the working efficiency are high.
