How to reduce the air leakage rate of pneumatic vacuum ball valve

2020-05-05

 How to reduce the air leakage rate of pneumatic vacuum ball valve:
1. pump and pneumatic vacuum ball valve connected to the pipeline, the use of arc transition, so that the gas road is not blocked, can be unimpeded.
2. as far as possible to avoid dead corners, should use high precision polishing, fully meet the applicable standards of vacuum.
3. to strengthen the pneumatic high vacuum ball valve surface polishing, so that it is not easy to absorb gas, vacuum effect.
4. Minimize the volume of the vacuum system and shorten the length of the pipeline system.
5  the material used in addition to the requirements of a smooth surface, no scratches, no cracks, but also requires a low permeability and the rate of air and good resistance to heat and oil, at the same time to have a certain strength, hardness and elasticity.
