D971X electric sandwich soft seal butterfly valve

Product advantage

The main advantages of D971X clamp type electric soft seal butterfly valve are simple structure, small size, light weight, low cost, the characteristics of pneumatic disc valve is especially significant, installed in the high altitude tunnel, convenient operation after two five-way solenoid valve control, and can also adjust the flow medium. Small fluid resistance, large diameter pneumatic disc valve fully open when the effective flow area is large, open and close quickly and save labor, the disc can be rotated 90 Angle to complete the opening and closing, because the medium force on both sides of the rotating shaft plate hand is close to equal, and the torque generated in the opposite direction, so the opening and closing torque is small, low pressure can achieve a good seal, the disc valve sealing material is rubber, fluorine rubber, Edible rubber, lined with tetrafluoroethylene, so the sealing performance is good, which hard seal disc valve for soft and hard laminated metal sheet with metal hard seal and elastic seal heavy advantages, regardless of low temperature conditions have excellent sealing performance.

Applicable environment

D971X clamp type electric soft seal butterfly valve structure working principle applicable environment analysis
The butterfly plate of D971X clamp type electric soft seal butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc disc rotates around the axis, the rotation Angle is between 0°~90°, and the valve is fully open when it is rotated to 90°.
The electric soft seal butterfly valve is simple in structure, small in size and light in weight, and is composed of only a few parts. And only need to rotate 90° can be quickly opened and closed, the operation is simple, and the electric valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is small, so it has better flow control characteristics. The butterfly valve has two types of seal: elastic seal and metal seal. Elastic sealing valve, the sealing ring can be inlaid on the valve body or attached to the butterfly plate around.
If the butterfly valve is required to be used as a flow control, the main thing is to correctly select the size and type of valve. The structure principle of butterfly valve is especially suitable for the production of large diameter valves. Butterfly valve is not only widely used in petroleum, gas, chemical industry, water treatment and other general industry, but also used in the cooling water system of thermal power station.

Working principle

Working principle of D971X clip-on electric soft seal butterfly valve
The valve with metal seal generally has a longer life than the valve with elastic seal, but it is difficult to achieve complete seal. Metal seals can adapt to higher operating temperatures, and elastic seals have temperature-limited defects.
