Structural features and application of high-pressure gate valves
Product features of high-pressure gate valves
- The seat sealing cover is made of iron-base chromium-nickel stainless steel surfacing, with good abrasion resistance.
- 2.The surface of the valve stem is treated with corrosion resistance nitriding, which has good corrosion resistance and abrasion resistance.
- 3.The closing and opening of the valve is controlled by an electric device mounted on the cover.
- 4.Electric device is equipped with special motor for valve, reducer box, torque control mechanism, stroke control mechanism, field operation mechanism, hand and electric switch mechanism respectively.
- 5.The valve switches are adjusted by the stroke control mechanism and the torque limit mechanism can be adjusted to protect the valve when the stroke control mechanism fails.
- 6.The valve is closed mainly by the electric device and can adjust the wedge double gate, universal top, clamping ring and other composition, by the guidance of the valve body for lifting movement.
- 7.Electric device can be operated at a distance besides local operation.
Structural features and application of high-pressure gate valves
- Electric high-pressure gate valves are of compact structure and reasonable design, with good valve rigidity, smooth passage and small flow resistance coefficient.
- The sealing surface of gate valve of high-voltage power station adopts stainless steel and hard alloy, with long service life.
- Electric high-pressure gate valves adopt flexible graphite packing, reliable sealing and flexible operation.
- Driving mode: separate operation, electric, pneumatic and gear drive, structural type: elastic wedge single gate valve, rigid wedge single gate valve and double gate valve.
- The gate valve of the high-pressure power station is widely applicable to oil products such as petrochemical industry, thermal power plant, and water steam pipe line to make connection or cut off the lifting device of intermediate pipeline.
