1. Adjust the cylinder stroke
1.Close the pneumatic butterfly valve, apply air pressure to the cylinder, and manually observe whether the stroke of the cylinder is accurate.
2.If the stroke is not accurate, first adjust the width of the cylinder baffle, that is, the valve disc stroke adjustment screw, and adjust the air cylinder stroke until it is accurate.
3.If the cylinder stroke can not reach the specified range, it is necessary to loosen the nut on the cylinder stroke limiter first, and roll the shaft by rotating the limiter, so that the limiter wheel rim is inserted and pulled out of the stroke limit hole, and the cylinder stroke is adjusted to the normal range.
2. Adjust the opening and closing force of the cylinder
1.Open the pneumatic butterfly valve and record the current cylinder pressure on the valve stem.
2.The adjustment of pressure or decompression is realized by rotating the end head screw of the cylinder, and the opening and closing force of the cylinder is adjusted to an appropriate degree.
3.Restart the first step and observe whether the adjusted opening and closing force meets expectations.
3. Adjust the speed of the cylinder
1.Adjust the air pressure regulating valve to control, and reduce the air pressure can increase the action speed of the cylinder.
2.The air pressure control valve can be dynamically adjusted according to the actual situation to achieve accurate adjustment and adapt to flow changes.
[Conclusion].
The above is the detailed method of adjusting the pneumatic butterfly valve cylinder. Through the steps introduced in this article, the stroke, opening and closing force and action speed of the pneumatic butterfly valve cylinder can be effectively adjusted, the control accuracy and reliability of the system can be improved, and the service life of the cylinder can be prolonged.
