O-pneumatic valve for air leakage means common are the following:
1. Cylinder upper and lower air leakage, which is due to the implementation agencies and the cylinder seals of the ring because of its frequent activities of the implementing agencies and not to seal the effect.
2. Cylinder vent leak, because the two moving parts inside the cylinder and the cylinder seal ring appears at the aging phenomenon.
3. Cylinder valve on the leak, probably due to the pressure relief valve too high.
4. In addition to the above 3 conditions, there are other conditions may also make a cylinder leak, the cylinder of the spring is damaged, not in place due to the result of force, which may result in customs not in place.
O-pneumatic valve leakage corresponding solution:
1. Replace the actuator ring.
2. Replace cylinder at the ring.
3. The pressure regulating valve is 3-5 kg, or is to open the ventilation valve at the lower part of action a few times, and sometimes may also replace the solenoid valve.
4. Replace cylinder in the spring.
Cylinder leakage problem solving must be in accordance with the actual situation to consider, for example, this ball valve is open air, or gas related. For the gas valve open, first hand can turn off the valves at both ends, and then let the control of this valve is opened, the connection first connection pieces apart, then cut off the gas supply at this time will be at the discharge valve out, pay attention to the executing agency will then turn 90
