Throttling working principle of the pneumatic valve and one-way throttle valve

throttling pneumatic valve is by changing the throttling section length or throttling to control the fluid flow pneumatic valves. To throttle pneumatic valve and one-way pneumatic parallel can be combined into one-way throttle valve pneumatic valve. Pneumatic valve throttle and one-way throttling flow control pneumatic valve pneumatic valve is simple and easy. Pneumatic valve throttle without flow feedback function, can't compensation caused by load changes speed is not stable, generally only used for load changed or to speed stability requirement is not high.
air port diameter P by throttling the function of throttling mouth after the output port A. Throttling orifice flow area and pneumatic valve core has the certain function relation between displacement, the function relationship related to the shape of the pneumatic throttle valve core part. Commonly used a needle type pneumatic valve and triangular groove tip type and cylindrical bevel type, etc. , with hydraulic throttle pneumatic valve pneumatic throttle valve core parts in the same shape, not repeat here. Here is cylindrical bevel throttling pneumatic valve of pneumatic valve core.
unidirectional throttle pneumatic valve it is a one-way pneumatic valve and throttle valve parallel combination of pneumatic valve control. When air flows from the P port to port A. After throttling pneumatic valve throttling; Flow in the opposite direction, that is, from A to P flows, one-way pneumatic valve to open, not throttling. One-way throttling pneumatic valve used in the speed of cylinder and delay circuit.
