1. Butterfly valve has the characteristics of simple structure, small volume, light weight, low material consumption, small installation size, quick switch, 90° reciprocating rotation, small driving torque, etc., used to cut off, connect, adjust the medium in the pipeline, with good fluid control characteristics and close sealing performance.
2, butterfly valve can transport mud, at the mouth of the least fluid accumulation. At low pressure, good sealing can be achieved. Good adjustment performance.
3. The streamline design of the butterfly plate makes the fluid resistance loss small. It can be said that it is an energy saving product.
4, The valve stem is through rod structure, after quenching and tempering treatment, has good comprehensive mechanical properties and corrosion resistance, abrasion resistance. When the butterfly valve is opened and closed, the stem only rotates and does not rise and fall. The packing of the stem is not easy to be destroyed and the seal is reliable. It is fixed with the disc taper pin, and the overhanging end is designed to prevent the stem from breaking out when the stem and disc are connected by accident.
5. There are flange connection, clamp connection, butt welding connection and lug clamp connection.
The driving forms are manual, worm gear drive, electric, pneumatic, hydraulic, electro-hydraulic linkage and other actuators, which can realize remote control and automatic operation.
