a. medium: nitrogen N2 or air (compressed, filtered and dried).
b. the maximum output pressure is less than 0.8Mpa.
c. Suction pressure range:0-20 psi
d.Exhalation pressure(Vacuum ranges):-20psi-0
e. clamping range (the diameter of the valve flange): DN15-DN300(1”-12”)
f. power supply: 220V, 50HZ.
i. environment temperature: -20℃~+60℃
Working Principle
fixed the breathing valve to allow the media to enter or suck out the inlet of the check valve. Medium pressure to rise (or fall) to the call (suction) valve open state, measured at this time the pressure value, that is, open pressure calibration.
is composed of gas source, automatic clamping platform and testing console.
gas source:The utility model is composed of a nitrogen gas cylinder, a vacuum pump, a pressure reducing valve, a pressure gauge, an electromagnetic valve, an energy storage tank and a water splitting gas filter.
automatic clamping table: the pneumatic clamping device and clamping pedestal etc..
detection console: the electric contact pressure gauge, pressure control device, buttons, switches, solenoid valves, inductive sensors, relays, vacuum pumps, pneumatic systems, etc..
