| description | The utility model discloses a pneumatic proportional pressure valve test device. The device comprises a test bench, the test bench is provided with two valve test tools, and each valve test tool is provided with a plurality of sensors; the test bench is also provided with a display, and the display is connected with a host machine; the host machine is provided with a data acquisition card, and input ports of the data acquisition card are connected with the sensors on the valve test tools through signal lines; an output port of the data acquisition card are connected with a control circuit module; the control circuit module is connected with a gas circuit module through a signal line; and the gas circuit module is connected with a load gas cylinder. The pneumatic proportional pressure valve test device can be used to carry out current-pressure characteristic tests, inlet pressure step response characteristic tests, pressure-flow characteristic tests, life tests, and tightness tests of a proportional pressure v |
