I use the new warrior's QLAH series high pressure check valve, which can indeed do, the principle of secondary compression, in the low pressure section, 1 mpa, in the high section, the pressure at 1 mpa. Because of the high compression rate of the compressor, the manufacturer has chosen an external pump for strong low temperature. The quality of this product is very demanding and the temperature is very high. The general situations in which the high pressure value cannot be used are

joint leakage: check at the seam foam wool has no leakage, high pressure two-position two-way solenoid valve if there is a gas leak, you can not use high pressure.

Explosion-proof valve failure: there is a gas leak around the explosion-proof valve. I use a pressurized gas machine with an explosion device. When the pressure reaches the limit, the explosion plate ruptures. Some valves have smaller inlet tracts, thus blocking the pressure in the line. All at once, there are more than 34. At this point, cracking, to replace the storm flap.

High-pressure throttle is not sealed: remove the high-pressure cylinder head, remove impurities, and replace with a new gas-tight ring.

High-pressure valve piece with impurities: ultra-high-pressure one-way solenoid valve to remove the high-pressure cylinder cover, remove impurities.

High pressure piston ring is damaged: remove the high pressure cylinder cover and check if there is a replacement.

Generally speaking, as long as the motor can turn, are no problem, you can go to the manufacturer!
