Structural Characteristics Of Butterfly Valve

- Nov 11, 2017 -

1. Butterfly valve with simple structure, small size, light weight, the material consumption of the province, installation size is small, switch quickly, 90° reciprocating rotation, driving torque is small and so on, used to truncate, connect, adjust the pipeline medium, with good fluid control characteristics and closure sealing performance.

2. The butterfly valve can carry the mud and accumulate liquid at the pipe mouth at least. Low pressure, can achieve good sealing. Good regulation performance.

3. The streamline design of the butterfly plate makes the fluid resistance loss small, it is a kind of energy-saving product.

4. Stem for the rod structure, after the quality control treatment, has good comprehensive mechanical properties and corrosion resistance, abrasion resistance. Butterfly valve opening and closing valve stem only for rotary movement, not for take-off and landing operation, valve stem filler is not easy to damage, sealed reliable. and the butterfly plate cone pin fixed, outside the extension end is the blowout-resistant design, lest the stem collapses when the valve stem and the Butterfly board connection place unexpectedly breaks.

5. The connection method is connected with flange connection, clamp connection, butt weld connection and lug clamp.

Drive form has manual, worm gear Transmission, electric, pneumatic, hydraulic, electro-hydraulic linkage, such as actuator, can achieve long-distance control and automation operation.
