Apparatus for performance test of gas regulator test method of hysteresis step function response and set point stability using the apparatus

摘要

The gas supply device includes a gas supply device for supplying a gas, a gas supply regulator for supplying a gas supplied from the gas supply device at a constant pressure, and a second gas supply device for interrupting the flow of gas flowing out from the gas supply regulator A first gauge for measuring the pressure of the gas flowing out from the gas supply regulator; and a port for moving the port, which is a portion coupled to the test regulator, as a portion through which gas introduced from the gas supply regulator is discharged, A second gauge for measuring the pressure of the gas flowing out of the test regulator, a second gauge for measuring the pressure of the gas flowing out of the test regulator, To block flow A second valve, and a flow controller for controlling the flow of gas flowing out from the test regulator, and a hysteresis, a flow rate change response and a set value stability test method using the same. According to the present invention, since the test regulator can be attached / detached by the button operation without tightening the nuts and the like by applying the sample matching device, the test time can be greatly shortened and the same test operation can be performed regardless of the skill of the tester , There is less risk of pressure loss and gas leakage.
