The principle of pneumatic valve
Pneumatic valves are valves driven by compressed air. When purchasing pneumatic valves, it is only necessary to specify the specifications, types, and working pressures to meet the purchasing requirements. flow. It is not perfect in the current market economy environment. Because the pneumatic valve manufacturers have carried out different innovations under the concept of unified design of pneumatic valves for product competition, they have formed their own corporate standards and product personality. Therefore, it is very necessary to put forward technical requirements in detail when purchasing pneumatic valves, and coordinate with manufacturers to reach a consensus as an accessory of the pneumatic valve purchase contract. This type of valve should generally be installed horizontally in the pipeline.
working principle
The compressed air is used to push the movement of multiple sets of combined pneumatic pistons in the actuator, and the force is transmitted to the characteristics of the beam and the inner curved track, which drives the hollow spindle to rotate. Direction, according to the requirements of the rotation torque required by the load (valve), the number of cylinder combinations can be adjusted to drive the load (valve) to work.
Two-position five-way solenoid valve is usually used with double-acting pneumatic actuator. Two positions are controllable in two positions: open-close. The air inlet and outlet of the outer air chamber of the acting cylinder are connected, and the two are connected to the air inlet and outlet of the inner air chamber. The specific working principle can refer to the working principle of the double-acting pneumatic actuator.
