Circular ventilation butterfly valve

A circular ventilation butterfly valve is a dust collector accessory valve that uses a circular butterfly plate as the opening and closing element and rotates with the valve stem to open, close, and regulate the fluid channel. The circular ventilation butterfly valve not only has a simple structure, small volume, light weight, low material consumption, small installation size, but also has small driving torque, easy operation, and good flow regulation function and closing sealing characteristics. In the use of large, medium, and low pressure, butterfly valve is the dominant form of valve. With the application of synthetic rubber and polytetrafluoroethylene, the performance of butterfly valves has been improved and can meet different operating conditions. In the past decade, the development of metal sealed butterfly valves has led to the widespread use of metal sealed butterfly valves under high temperature, low temperature, and strong erosion conditions, with the application of materials such as low temperature resistance, strong corrosion resistance, and strong erosion resistance in butterfly valves. They have partially replaced globe valves, gate valves, and ball valves.

The structural characteristics of circular ventilation butterfly valves:

The circular ventilation butterfly valve has the characteristics of simple structure, small volume, light weight, low material consumption, small installation size, switch, 90 ° reciprocating rotation, and small driving torque. It is used to cut off, connect, and regulate the medium in the pipeline, and has good fluid control characteristics and closing sealing performance.
