The two gas circuits are respectively connected with positive pressure regulating valve and negative pressure regulating valve from the outside. We can change the air pressure input into the air circuit through the pressure regulating valve. We can observe the current input air pressure by using high-precision digital pressure gauge, so as to accurately obtain the required pressure for the test.
The solenoid valve added in the air circuit can control whether the air circuit is ventilated, and can simplify some of our operation. The two solenoid valves are connected with an mts-103 button switch, the common end of the button switch is connected with the power supply, and the NNT solenoid valve is connected with the electric source respectively by turning the button switch in different directions to realize the selection of positive and negative pressure gas circuits.
