Butterfly Valve has a simple structure, small size, lightweight, low material consumption, small installation size, quick switch, 90 reciprocating rotation, driving torque small stem structure, after conditioning treatment, it has good comprehensive mechanical properties, corrosion resistance and abrasion resistance. When the butterfly valve opens and closes, the valve stem only makes the rotation movement and does not make the lifting movement, the valve stem packing is not easy to destroy, the seal is reliable. Fixed with the taper pin of the butterfly plate, the extended end is designed to prevent punching out, so as to avoid the valve rod bursting out when the connecting place of the valve rod and the butterfly plate breaks accidentally.
Introduction of Butterfly Valve
1. The Butterfly Valve has the characteristics of simple structure, small volume, light weight, low material consumption, small installation size,responsive, 90 reciprocating rotation, small driving Torque, etc. . It is used for cutting off, connecting and regulating the medium in the pipeline, it has good fluid control characteristics and sealing performance.
2. The Butterfly Valve can transport mud and minimize the accumulation of liquid at the pipe mouth. Under low pressure, a good seal can be achieved. Good adjustability.
3. Butterfly plate streamline design, so that fluid resistance loss is small, can be described as an energy-saving product.
4. The valve stem is through-stem structure, after conditioning treatment, has good comprehensive mechanical properties and anti-corrosion, anti-abrasion. When the butterfly valve opens and closes, the valve stem only makes the rotation movement and does not make the lifting movement, the valve stem packing is not easy to destroy, the seal is reliable. Fixed with the taper pin of the butterfly plate, the extended end is designed to prevent punching out, so as to avoid the valve rod bursting out when the connecting place of the Valve Rod and the butterfly plate break accidentally.
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 actuator, can achieve long-distance control and automatic operation.
There are three criteria for butterfly valve selection:
1. According to the parameter model, specification, size selection of the appropriate butterfly valve
2. Whether has the regular production qualification and the product inspection report
3. The material to ensure that the use of hydraulic system must be dedicated to the butterfly valve
4. Butterfly Valve structure to be reasonable, in order to have a stronger product.
