High Performance Butterfly Valve, Butterfly Valve, Ductile Iron
Butterfly valves are not only simple in structure, small in volume, light in weight, low in material consumption, small in installation size, small in driving moment, simple in operation and fast in operation, but also have good flow regulation function and sealing characteristics. They are one of the fastest growing valve varieties in recent decades. Butterfly valves are widely used. The variety and quantity of its use are still expanding, and it is developing towards high temperature, high pressure, large caliber, high sealing, long life, excellent regulation characteristics and multi-function of a valve. Its reliability and other performance indicators have reached a high level.
Butterfly valves are suitable for flow regulation. Because the pressure loss of butterfly valve in the pipe is relatively large, about three times that of gate valve, when choosing butterfly valve, the influence of pressure loss on pipeline system should be fully considered, and the strength of butterfly plate under pipeline medium pressure when closing should also be considered. In addition, the working temperature limitation of elastic seat material at high temperature must also be considered.
1. The butterfly valve has the characteristics of simple structure, small volume, light weight, low material consumption, small installation size, fast switching, 90 degree reciprocating rotation and small driving moment. It is used to cut off, connect and regulate the medium in the pipeline, and has good fluid control characteristics and sealing performance.
2. Butterfly valves can transport slurry and store the least liquid at the mouth of the pipeline. Good sealing can be achieved under low pressure. Good regulation performance.
3. The streamlined design of butterfly plate can reduce the loss of fluid resistance, so it is an energy-saving product.
4. The valve stem is a through-rod structure. After quenching and tempering treatment, it has good comprehensive mechanical properties, corrosion resistance and scratch resistance. When the butterfly valve is opened and closed, the stem is only rotated but not lifted. The filler of the stem is not easy to destroy and the seal is reliable. Fixed with the butterfly plate cone pin, the extension end is anti-washout design, so as to avoid the valve stem collapse when the connection between the stem and the butterfly plate accidentally breaks.
5. The driving forms are manual, worm wheel drive, electric, pneumatic, hydraulic, electro-hydraulic linkage and other executing mechanisms, which can realize long-distance control and automatic operation.
1. Opening and closing is convenient, fast, labor-saving, fluid resistance is small, and can be operated frequently.
2. It is simple in structure, small in size, short in length, small in volume and light in weight. It is suitable for large caliber valves.
3. The slurry can be transported and the least liquid can be stored at the outlet of the pipeline.
4. Good sealing can be achieved under low pressure.
5. Good regulation performance.
6. When fully open, the effective flow area of seat passage is larger and the fluid resistance is smaller.
7. The opening and closing moment is small. Because the butterfly plates on both sides of the rotating shaft are basically equal to each other under the action of medium, the direction of the generating torque is opposite, so the opening and closing is more labor-saving.
8. Sealing surface materials generally use rubber, so low-pressure sealing performance is good.
9. Easy installation.
10. Flexible and labor-saving operation. Manual, electric, pneumatic and hydraulic modes can be selected.
