Inform you of the working principle of pneumatic butterfly valve
When the ball valve is free from external force, its natural extension is at the minimum stroke (the tightening stroke), which is the maximum extension advantage;? The air pressure on both sides of the piston is equal. Due to the different force bearing areas, the pressure difference is generated to provide the support force for the pneumatic butterfly valve; The total support force provided instantaneously during the movement of pneumatic butterfly valve includes two parts: support force and friction force generated by pressure difference. External tightening pneumatic butterfly valve. As the volume of the strut in the air chamber increases, the effective volume of the compressed gas decreases, the air pressure in the air chamber increases, and the support force generated by the pressure difference increases;??
Friction change:??
The greater the air chamber pressure is, the greater the friction is,??
The faster the strut moves, the greater the friction,??
The farther away from the advantages of natural stretching, the greater the friction?
The air temperature affects the supporting force of the pneumatic butterfly valve: the lower the air temperature, the lower the air chamber pressure, and the smaller the supporting force provided by the pneumatic butterfly valve.
