The butterfly valve is suitable for flow regulation. Since the pressure loss of the butterfly valve in the pipeline is relatively large, it should also be considered that the butterfly plate is subjected to the firmness of the pressure of the pipeline medium when it is closed.
Butterfly valve has the characteristics of simple structure, small volume, light weight, material consumption, small installation size, rapid switch, 90° reciprocating rotation and small driving torque.
The butterfly valve is a valve that uses a disc type opening and closing member to reciprocate about 90° to open, close or adjust the flow of the medium.
In the 1930s, the United States invented the butterfly valve. It was introduced to Japan in the 1950s and was widely used in Japan in the 1960s. In China, it was promoted in the 1970s. The main features of the butterfly valve are: small operating torque, small installation space and light weight.
The butterfly valve, also known as the flap valve, is a simple regulating valve. The butterfly valve that can be used for the switching control of the low-pressure pipeline medium means that the closing member (valve or disc) is a disc that rotates around the valve shaft to achieve opening and closing. a kind of valve.
