1. The valve comprehensive air tightness test stand consists of 5 channels, the inlet input air source pressure is 15 MPa, and the compressed air output is 5 channels. The pressures are: 0-10 MPa, 0-16 MPa, 0-25 MPa, 0-60 MPa, 0-80 MPa. The deflation pipeline is 1 channel (5 channels output integrated 1 channel deflation), the test pressure can be outputed in two ways, independently and combinedly.

2. System working pressure≤15MPa, navigation mark 37° inner cone, air source inlet diameter ≥6mm, test system pressure pipeline diameter ≥ 6mm.

3. The inlet and outlet of the system are all equipped with filters, the inlet filtration precision is not less than 10um, the outlet filtration precision is not less than 5μm; the inlet and outlet are all equipped with mechanical pressure gauges.
