1. Butterfly valve has the characteristics of simple structure, small volume, light weight, low material consumption, small installation size, fast switch, 90 ° reciprocating rotation, small driving torque, etc. It is use to cut off, connect and regulate the medium in the pipeline, with good fluid control characteristics and closing sealing performance.
2. The butterfly valve can transport mud, with the least liquid accumulated at the pipe mouth. Under low pressure, good sealing can achieve. Good regulation performance.
3. The streamlined design of butterfly plate makes the loss of fluid resistance small, which can describe as an energy-saving product.
4. The valve rod is a through rod structure. After tempering treatment, it has good comprehensive mechanical properties, corrosion resistance and scratch resistance. When the butterfly valve is open and close, the valve rod only rotates without lifting. Therefore, the packing of the valve rod is not easy to damage. And the sealing is reliable. It is fixed with the taper pin of the butterfly plate. However, the extension end is designed to prevent the valve rod from bursting out when the valve rod is accidentally broken at the connection of the valve rod and the butterfly plate.
5. The connection methods include flange connection, clamp connection, butt welding connection and lug clamp connection.
