Do you know what are the problems in the process of pneumatic ball valve operation?

In recent years, with the continuous development and progress of the industrial industry,Pneumatic ball valveWidely used in all kinds of industrial industries,Pneumatic ball valveIt has become a control valve in the production process of many industrial enterprises, and it is also an important component of industrial piping system automation equipment. The use of pneumatic ball valve in industrial production can bring convenience to industrial production, especially long-term continuous production equipment. However, due to the pneumatic ball valve components in the use of the process, affected by various factors constitute part of the damage, and then there will be shortcomings. If the pneumatic ball valve defects, then the entire system operation will be affected. Therefore, it is very important to find the shortcomings of pneumatic ball valve in time and adopt useful measures.
The following summarizes the common shortcomings of pneumatic ball valve in the process of operation, the primary existence of pneumatic ball valve leakage increased, unstable action, vibration, action, pneumatic ball valve does not move and other shortcomings, and analyzes the causes of these shortcomings. Hope for the relevant operators to deal with the shortcomings of pneumatic ball valve supply response ideas.

1. Pneumatic ball valve leakage increased shortcomings and reasons
Pneumatic ball valve leakage depends primarily on the ball valve switch. To sum up, the increase in leakage of pneumatic ball valves is mainly due to the following two factors: first, the valve core in the stainless steel pneumatic ball valve is worn due to long application time, resulting in the ball valve not closing tightly and then causing the leakage to increase; Second, when the pressure difference between various media is large, the rigidity will decrease, causing the ball valve to fail to close, after all, causing the leakage of pneumatic ball valve to increase.
2. Pneumatic ball valve action instability shortcomings and reasons
The reasons for the unstable action of the pneumatic ball valve may be: ① the signal voltage is unstable; ② the gas source pressure is unstable.
3. Pneumatic ball valve vibration shortcomings and reasons
Pneumatic ball valve is briefly affected by the surrounding environmental factors in the operation process. After a long period of operation, the sealing packing and the valve core will form a gap under the effect of conflict. Mechanical equipment with other vibration around the pneumatic ball valve and unbalanced orientation of the pneumatic ball valve equipment will cause the pneumatic ball valve to vibrate.
4. Pneumatic ball valve action flagging shortcomings and reasons
When the stem is bent and deformed, it will increase the resistance of its reciprocating action, causing the pneumatic ball valve to relax. When graphite and asbestos filler lubricating oil and PTFE filler are abnormal, it will also cause the pneumatic ball valve to relax. When dust exists inside the valve body and a locator is equipped inside the pneumatic ball valve, it will increase the resistance of the pneumatic ball valve stem to run, and then cause the pneumatic ball valve to relax.

5. Pneumatic ball valve does not operate and the reason
The gas source and signal are used as the conditions and foundation to ensure the smooth operation of the pneumatic ball valve. Assuming that the positioner has no air source, the pressure reducing valve may have defects, and in severe cases, the filter and pipeline may be blocked. If the positioner has an air source, but there is no output, the saving hole of the positioner will be blocked. Assuming that there is no air source and signal, when the temperature is low and the air source is not turned on, the compressor will fail due to blockage of the pressure reducing valve and air pipe, after all, resulting in defects. Assuming that there is an air source but no signal, the diaphragm of the conditioning network will be damaged, and then the bellows of the locator will leak.
When the pneumatic ball valve operation of the above shortcomings, should be based on the reasons for the shortcomings of the use of appropriate measures.
