1 Inch Proportional Butterfly Valve Cast Iron
Butterfly valve structure
It is mainly composed of valve body, valve stem, butterfly plate and sealing ring. The valve body is cylindrical, with a short axial length and a built-in butterfly plate.
Features
1. The butterfly valve has the characteristics of simple structure, small size, light weight, low material consumption, small installation size, fast switching, 90 ° reciprocating rotation, and small driving torque. It is used to cut off, connect, and adjust the medium in the pipeline. Has good fluid control characteristics and closed sealing performance.
2. The butterfly valve can transport mud, and the least liquid accumulates in the pipe mouth. At low pressure, a good seal can be achieved. Good adjustment performance.
3. The streamlined design of the butterfly plate makes the fluid resistance loss small, which can be described as an energy-saving product.
4. The valve stem is a through-rod structure. After quenching and tempering, it has good comprehensive mechanical properties, corrosion resistance and scratch resistance. When the butterfly valve is opened and closed, the valve stem only rotates and does not move up and down. The packing of the valve stem is not easy to damage and the seal is reliable. It is fixed with the taper pin of the butterfly plate, and the outgoing end is designed to prevent rushing out, so as to prevent the valve stem from collapsing when the connection between the valve stem and the butterfly plate is accidentally broken.
5. Connection methods include flange connection, clip connection, butt welding connection and lug clip connection.
The driving form includes manual, worm gear transmission, electric, pneumatic, hydraulic, electro-hydraulic linkage and other actuators, which can realize remote control and automatic operation
