Wafer Type Butterfly Valve

Wafer type butterfly valve is a kind of fluid control equipment, which is used to regulate or isolate the fluid flow in the system. This valve is named for its unique design, which is similar to the design of thin sheet or disc. It consists of a disc mounted on a rotating shaft. When the valve is closed, the flow of fluid is blocked by rotating the disc 1. The wafer butterfly valve is suitable for water and other media, and can be driven by manual operation. It can be used at ordinary temperature (-40 ℃) 2. They are quarter turn valves, sandwiched between the two flanges of the pipeline, suitable for closing the entire pipeline, and have strong sealing performance of rubber or EPDM seats

The working principle of wafer butterfly valve is to open or close the valve by rotating the disc-shaped butterfly plate in the valve body around the central axis. The rotation angle can vary from 0 ° to 90 °. When the rotation angle is 0 °, the butterfly plate is parallel to the valve body, and the valve is closed at this time; When the rotation angle reaches 90 °, the butterfly plate is fully opened and the valve is in the maximum opening state 146. The wafer butterfly valve is simple in structure, small in size and light in weight. It is mainly composed of a few parts, including valve body, valve seat, valve stem, butterfly plate and wafer clamping device, etc
