1 minute take you understand the purpose of the common pneumatic valve and the difference!

of commonly used controls on the industrial pipeline and equipment mainly refers to some commonly used pneumatic valve, it is used to control the medium flow in pipe. Pneumatic valve is commonly used in modern life have butterfly pneumatic valve, pneumatic ball valve, plug valve, check valve pneumatic valve, pneumatic valve and exhaust valve ( Here in bo sea on the secondary water supply equipment of pneumatic valve as an example in detail) 。

butterfly butterfly pneumatic valve pneumatic valve has simple structure, small volume, light weight, only by a few parts. And simply rotate ° rapid opening and closing, simple operation, at the same time has good flow control characteristics. Butterfly pneumatic valve in the fully open position, the disc plate thickness is medium flows through the only pneumatic valve body resistance, and therefore the pressure produced by the pneumatic valve will be small, it has good flow control characteristics. http://www。 zgbfw。 Com/info /

the commonly used control pneumatic valve has the wafer butterfly valve and flanged butterfly pneumatic valve two kinds. Wafer butterfly valve pneumatic valve pneumatic valve is in the stud connection in place between two pipe flanges. Pneumatic valve flange butterfly is pneumatic valves with flange, bolts on the pneumatic valve flange connection on the pipe flange on both ends.
choose features: butterfly pneumatic valve suitable for installation on the large diameter pipe. Pneumatic valve

cock cock pneumatic valve is also called kock or revolving door. It is mainly composed of pneumatic valve and plug ( Conical or cylindrical. The hot water faucet also belong to cock a pneumatic valve. http://www。 zgbfw。 Com/info /

choose features: simple structure, small overall dimensions, opening and closing fast, convenient operation, small fluid resistance, easy to manufacture three-way or four-way pneumatic valves, to make a distribution of commutation. But the sealing surface wear, switch power is larger. This kind of pneumatic valve is not suitable for conveying high pressure medium ( Such as steam, is only applicable to general low-pressure fluid for open and close, for adjusting flux is unfavorable to use. Pneumatic valve

check the check list of pneumatic valve and flow pneumatic valve or non-return valve, it is a kind of according to the pressure difference between before and after pneumatic disc and automatic opening and closing of the pneumatic valve. It has strict direction, only the medium flow in one direction, and prevent the reverse flow. Don't turn back the hands of medium in the pipeline, such as for water pump outlet pipe road as protection device of water pump when the pump is stopped. http://www。 zgbfw。 Com/info /

choose features: generally applicable clean medium, for larger with solid particles and the viscous medium shall not apply.

pneumatic ball valve pneumatic ball valve open-close part ( A sphere) Driven by pneumatic valve stem, and around the pneumatic ball valve axis rotation movement of the pneumatic valve. Pneumatic ball valve in the line is mainly used to do cutting, distribution, and change the flow direction of medium, it only need to use rotation operation and small rotational torque can be closed tightly. Pneumatic ball valve is suitable to do the most switch, cut off the pneumatic valve is used. http://www。 zgbfw。 Com/info /

choose features: suitable for fiber, tiny solid material, such as medium.

exhaust exhaust pneumatic valve pneumatic valve in the pipe system is indispensable auxiliary components, are widely used in boilers, oil and gas, water supply and drainage pipeline. Often installed in the place such as the commanding heights or bend, get rid of extra gas pipeline, pipe road use efficiency and reduce energy consumption. http://www。 zgbfw。 Com/info /

choose features: used in floor heating system, central air-conditioning exhaust pipe pneumatic valve

one is essentially a dynamic balance differential pressure pneumatic valve and an electric regulating pneumatic valve close 2 for one, double pneumatic valve cone structure can adjust the dynamic balance. http://www。 zgbfw。 Com/info /

choose features: suitable for heating control of a network of water supply, building automatic control to water balance. http://www。 zgbfw。 com/info/
