Flexible throttle the working principle and the main points of attention in use

The working principle of Flexible throttle figure, relying on a flexible rubber pipe and throttle valve lever clamp, and can also use the gas pressure to replace the stem compression hose.Flexible throttle simple structure, small pressure drop, high reliability and action.To be not sensitive to pollution, usually working pressure range of 0.3-0.63MPa.

Application of pneumatic flow control valve for pneumatic actuator speed, the speed difficult than using hydraulic flow control valve, due to the compressibility of gases.So the pneumatic flow control valve speed control should pay attention to the following points, in case of:

(1) On the pipeline and no leakage phenomenon;

(2) The cylinder, the lubricating state between piston is better;

(3) The flow control valve should be installed in the vicinity of the cylinder or motor;

(4) As far as possible the export of throttle governing;

(5) The stability of the load shall be applied.If the change of external load large, the use of hydraulic or mechanical devices (such as the pneumatic and hydraulic linkage) to compensate for the load caused by changes in the rate of change.
