The working principle of pneumatic ball valve
The working principle of pneumatic ball valve
Pneumatic ball valve ball is transformed from the plug valve, its center of the ball for the rotation of 90° action, the ball around the valve body center line for rotation to achieve the opening, there is a circular through hole or channel through its axis. When the ball center rotates to 90°, the valve is in the closed state. When the actuator is working, it only needs a small torque to close the valve tightly, so as to achieve the principle of quick cut-off.
Pneumatic ball valves are mainly used in the rapid cutting, distribution and change of media in the flow of the pipeline. Pneumatic ball valve it opens and closes quickly, suitable for the use of large and small caliber. The use of v-shaped sphere can accurately adjust the media flow. Pneumatic ball valve structure has two kinds of distinction, one is the o-type ball core, o-type ball valve valve core for floating precision casting, flow channel mouth and pipe diameter is the same, mainly used as a cut-off switch. The other is a v-shaped ball core, which adopts a fixed structure with a v-shaped notch on the ball core. After installing a locator on the actuator, the proportion of the medium containing fiber and particle can be adjusted.
Installation of pneumatic ball valve
1, any section of the pneumatic pipeline ball valve can be installed in the upstream end, handle pneumatic pipeline ball valve can be installed in any position of the pipeline, if equipped
Pneumatic pipeline ball valves with actuators (such as gearboxes and electric-pneumatic actuators) must be installed vertically with the valve inlet and outlet in a horizontal position.
2, pneumatic pipe flange between the ball valve flange and the pipeline flange according to the pipeline design requirements on the gasket.
3. The bolts on the flange shall be tightened symmetrically, step by step and evenly.
4, if the pneumatic pipeline ball valve pneumatic, electric actuator, according to the instructions to complete the installation of air source, power supply.
