Butterfly valve working principle | scope

Butterfly valve working principle | scope letter mau butterfly valve working principle is to use disk type opening and closing a reciprocating rotary 90 & deg; About to open, close or adjusting medium flow of a valve. Butterfly valve is not only simple structure, small volume, light weight, material consumption province, small installation size, driving moment, simple operation, rapid, and can also have a good flow regulating function at the same time and close the seal characteristics, is one of the fastest growing valves varieties in last decade. Butterfly valve has a very wide range of use. The number of varieties and its use continues to expand, and to high temperature and high pressure, large diameter, high sealing, long service life, good features, the regulation of multi-purpose development and a valve. Its reliability and other performance indexes reach a higher level. Butterfly valve in the configuration of different actuators, can evolve into electric butterfly valve, pneumatic butterfly valve, hydraulic control butterfly valve and the electric hydraulic butterfly valve, letter mau butterfly butterfly valve is suitable for the application scope of traffic regulation. Because of the butterfly valve in the pipeline pressure loss is bigger, also should consider closing butterfly plate consistence of pipeline medium under pressure. In addition, you must consider resilient seat materials at high temperature on the operating temperature limit. The structure of the butterfly valve length and smaller overall height, opening and closing speed, and has good flow control characteristics, the structure principle of butterfly valve is most suitable for the production of large diameter valves. When the butterfly valve for control flow using one of the most important is correct choose the size and type of butterfly valve, and making it work properly and effectively. Butterfly valve still has an important characteristic is: suitable for large diameter valves, at present, our company has can produce 8 m butterfly valve, mature technology. In addition, the butterfly valve can be used to do the switch valve, cut-off valve. The article starts: WWW. zjxmfm。 com
