Butterfly Valve Structure Features
May 24, 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 may carry the mud, accumulates the liquid at the pipeline mouth at least. Low pressure, can achieve good sealing. Good regulation performance.

3, butterfly plate streamline design, so that the loss of fluid resistance is a kind of energy-saving products.

4, stem for the rod structure, after the quality control, 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 has the flange connection, to the clamp connection, the butt-weld connection and the lug to the clamp connection.

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