China [CN] Overview of pneumatic regulating ball valve:
According to the structural form, the pneumatic regulating ball valve can be divided into pneumatic O-type regulating ball valve or dynamic V-type regulating ball valve. It is mainly used with the valve positioner to make a press signal according to the input and output 4.20mA, so that
Control the rotation opening of the ball valve valve. To achieve the proportional adjustment of pipeline medium pressure, flow rate, liquid door and other parameters, among them, the pneumatic/type adjustment glass closure has knotted and removed shape objects (throwing gaps, which can adjust the flow rate according to the change of the opening area in the middle of the field, and can cut off the fluid Closed by impurities contained in the medium, suitable for the control of pulp, mortar, viscous fluid,
Pneumatic regulating ball valve principle:
The pneumatic regulating ball valve uses compressed air as the driving force to drive the ball flower to rotate back and forth, so as to achieve the opening and closing of the valve. Size, to achieve different degrees of proportional adjustment to the medium flow. When the pneumatic actuator receives the signal from the control system, it generates a corresponding thrust according to the size of the control force, and pushes the adjustment mechanism to drive the valve core to move, and completes the flow and pressure adjustment of the medium in the pipeline. It has a large rated flow coefficient. , good sealing effect, adjustable performance, etc.
