Dust removal D200 butterfly valve, dust removal plug valve

mainlyvalve bodyValve stem, butterfly plate, andsealing ringform. The valve body is cylindrical in shape, with a short axial length and a built-in butterfly plate.

feature

1. Butterfly valves have the characteristics of simple structure, small volume, light weight, low material consumption, small installation size, fast opening and closing, 90 ° reciprocating rotation, and small driving torque. They are used to cut off, connect, and regulate the medium in pipelines, and have good fluid control characteristics and closing sealing performance.

2. Butterfly valves can transport mud and accumulate liquid at pipeline openings. Under low pressure, good sealing can be achieved. Good regulation performance.

3. The streamlined design of the butterfly plate reduces fluid resistance loss, making it an energy-saving product.

The valve stem is a through stem structure that has undergone quenching and tempering treatment, and has good comprehensive mechanical properties, corrosion resistance, and abrasion resistance. When the butterfly valve is opened and closed, the valve stem only rotates and does not move up or down. The packing of the valve stem is not easily damaged and the seal is reliable. Fixed with the butterfly plate cone pin, the extended end is designed to prevent the valve stem from bursting out in case of accidental breakage at the connection between the valve stem and the butterfly plate.

5. The connection methods include flange connection, clamp connection, butt welding connection, and lug clamp connection.

The driving forms include manual, worm gear transmission, electric, pneumatic, hydraulic, electro-hydraulic linkage, etcactuatorIt can achieve remote control and automated operation.

advantage

1. Easy and quick opening and closing, labor-saving, low fluid resistance, and can be operated frequently.

2. Simple structure, small external dimensions, short structural length, small volume, light weight, suitable for large-diameter valves.

3. It can transport mud and accumulate liquid at the pipeline mouth.

4. Under low pressure, good sealing can be achieved.

5. Good regulation performance.

6. When fully open, the effective flow area of the valve seat channel is larger and the fluid resistance is smaller.

7. The opening and closing torque is relatively small, and due to the fact that the butterfly plates on both sides of the shaft are subjected to the same medium effect, the direction of torque generated is opposite, making opening and closing more effortless.

8. The sealing surface material is generally made of rubber or plastic, so it has good low-pressure sealing performance.

9. Easy to install.

10. Flexible and labor-saving operation, available in manual, electric, pneumatic, and hydraulic modes.
