Top mounted double eccentric hemisphere valve is a commonly used valve type, which is widely used in industrial production with its excellent performance and advantages. The advantages of the top mounted double eccentric hemisphere valve will be introduced from three aspects: reducing air leakage, reducing friction resistance and improving flow control capability.
Reduce air leakage
Air leakage is a problem existing in many valves, which will lead to energy waste and environmental pollution. The top mounted double eccentric hemisphere valve adopts a special structural design, which can ensure the fitting of the valve disc and the sealing surface during the valve closing process, thus reducing the leakage to some extent. In addition, the valve is also equipped with a sealing ring to prevent air leakage caused by medium erosion and wear. Compared with the traditional valve type, the air leakage rate of the top mounted double eccentric hemisphere valve is significantly reduced, and the working efficiency of the system is greatly improved.
Reduce friction resistance
Friction resistance is an inevitable problem in valve operation, which will cause the valve to be stuck, stuck and other phenomena in the process of opening and closing, affecting the normal operation of the valve. However, the top mounted double eccentric hemisphere valve adopts a double eccentric arch structure design, which reduces the contact area between the valve disc and the sealing surface, thus reducing the friction resistance. In addition, the valve also uses a special hydraulic balance mechanism to make the valve switch more light and smooth. Therefore, the top mounted double eccentric hemisphere valve shows good anti-wear and easy operation performance under high temperature, high pressure and large flow conditions.
Improve flow control capability
Flow control is one of the important functions of the valve, and the top mounted double eccentric hemisphere valve has special advantages in flow control. The valve is equipped with special V-shaped groove hemispherical flap and seal ring, which can realize accurate adjustment and control of flow during opening change. In addition, the double offset structure design between the valve seat and the valve disc can also reduce the gate effect of the valve and inhibit the shear and oscillation of the fluid. Therefore, the top mounted double eccentric hemisphere valve has good fluid control ability and can meet the strict requirements under complex working conditions.
The top mounted double eccentric hemisphere valve has the advantages of reducing air leakage, reducing friction resistance and improving flow control ability. Its superior performance not only improves work efficiency, reduces energy waste, but also ensures the full operation of the system. With the continuous progress of science and technology, the top mounted double eccentric hemisphere valve will continue to develop and improve, bringing greater convenience and benefits to industrial production.
