Butterfly valve knowledge

Air, water, steam, various corrosive media, mud, oil, liquid metals, radioactive media and other types of fluid flow can be controlled through the butterfly valve, mainly cutting off and throttling pipelines. Disc-shaped butterfly plate as the opening and closing parts, in the valve body around its own axis rotation, to achieve the purpose of opening and closing or regulation.

　　Butterfly valve is a kind of valve that opens, closes or regulates the flow of medium by making the disk switching element reciprocate about 90 degrees. It has simple structure, small volume, light weight, low material consumption, small installation size, small driving torque, simple and fast operation, good flow regulation and closing sealing characteristics. It is one of the valve varieties that have developed rapidly in the last decade. The types and number of applications are moving towards high temperature, high pressure, large diameter, high sealing performance, long service life, excellent regulating characteristics and a valve multi-purpose direction. Its reliability and other performance indicators have reached a high level. Butterfly valve manufacturer

　　Butterfly valve manufacturer told butterfly valve, it is suitable for flow regulation. Due to the large pressure loss in the pipeline, about three times that of the gate valve, the impact of pressure loss on the pipeline system should be fully considered in the selection, and the strength of the butterfly valve under the pressure of the pipeline medium should also be considered. In addition, it is also necessary to consider the working temperature limit of the elastic valve seat material at high temperature.

　　Butterfly valve structure length and overall height is smaller, faster opening and closing speed, good fluid control characteristics. This structural principle is suitable for manufacturing large diameter valves. When the use of flow control is required, it is important to select the correct specification and type so that they can work properly and effectively.
