The structure characteristic of butterfly valve
- Jun 04, 2018 -
1, butterfly valve has a simple structure, small size, light weight, material consumption, small installation size, switch quickly, 90° reciprocating rotation, small driving torque, etc., used to cut, connect, adjust the media in the pipeline, with good fluid control characteristics and close sealing performance.
2, butterfly valve can transport mud, at the mouth of the pipeline to accumulate liquid minimum. Under low pressure, good sealing can be achieved. Good adjustment performance.
3, butterfly plate streamlined design, so that the loss of fluid resistance is a small energy-saving products.
4, valve stem for the rod structure, after the quality treatment, has a good comprehensive mechanical properties and corrosion resistance, abrasion resistance. Butterfly valve at the opening and closing valve stem only for rotation movement and not for take-off and landing operation, stem filler is not easy to destroy, sealed reliable.
and the butterfly plate cone pin fixed, the outside extension end is the anti-punching type design, lest when the stem and the butterfly plate connection accident Break when the stem collapses.
5, the connection way has the flange connection, to the clamp connection, to the welding connection and the lug to clamp connection. Drive form has manual, worm gear Transmission, electric, pneumatic, hydraulic, electro-hydraulic linkage and other executing agencies, can achieve long-distance control and automation operation.
