The pneumatic valve of nitrogen machine maintenance does not work for the following reasons:
1, nitrogen machine drive air source is not opened or opened too small;
2, the driving gas pressure is too low, the normal range is generally 0.4 ~ 0.6MPa;
3. There is dirt stuck in the valve of the nitrogen machine, or the valve pipeline is seriously vented;
4, the valve life has arrived, at this time need to replace the nitrogen machine pneumatic valve (life of about 6 years).
