气动硬密封蝶阀

产品介绍

Pneumatic Hard Seal Butterfly Valve uses a "U" type stainless steel sealing ring. The utility model solves the disadvantage that the traditional eccentric butterfly valve is still in sliding contact friction when the opening and closing is 0° to 10°, and the sealing surface of the butterfly plate is separated at the instant of opening, and the effect of closing the contact or sealing is achieved, thereby prolonging the service life and increasing the sealing performance.

Therefore, it is applied to the pipeline of corrosive medium such as metallurgy, electric power, petroleum, chemical, air, gas, combustible gas and water supply and drainage with medium temperature ≤550 °C, which is a device for regulating flow and shutting off fluid.

产品特点

1. Simple structure, compact, light weight, easy to install and disassemble, and easy to maintain;

2. Using stainless steel "U" type sealing ring, has a certain elasticity and excellent sealing performance, both in high temperature and low temperature.

3. Three-dimensional eccentricity, after strict calculation, the "U"-type sealing ring and the butterfly plate have almost no friction,also the sealing surface of the butterfly plate is made of surfacing cobalt-based hard alloy, the sealing surface is wear-resistant and has a long service life;

4. The structure is unique, the "switch" can only be completed by turning the valve stem 90 °. The operation is flexible, convenient, labor-saving, free from the influence of medium pressure.

5. High temperature resistance, low temperature resistance, corrosion resistance.
