Performance changes of butterfly valves with different eccentric structures

In our eyes, the performance of eccentric structure butterfly valves varies. Below, we will learn about the performance changes of different eccentric structure butterfly valves:

As the eccentricity of the valve plate increases and the thickness of the valve plate also increases, the resistance of fluid flowing through the three eccentric butterfly valve increases; As the eccentricity of the butterfly valve increases, PTFE lined valve The performance of valves also undergoes significant changes. Fluorine lined valve factory From the comparison of four different structures of butterfly valves, it can be seen that the three eccentric butterfly valve can generate a significant pressure drop and can be used as a regulating valve; The pressure drop of fluid flowing through the valve increases with the increase of eccentricity; But compared with some other non butterfly valves, the pressure drop of the three eccentric butterfly valve is still relatively small.

As the eccentricity of the butterfly valve changes, the sealing performance of the valve seat also changes, and the three eccentric butterfly valve has good sealing performance of the valve seat. As the number of eccentricities increases, the torque required for opening and closing the valve decreases, so the torque required for opening and closing the three eccentric butterfly valve is much smaller than other types of butterfly valves. With the change of eccentricity, for clamp type Fluorine-lined Butterfly Valve The temperature and pressure rating range and applicable temperature range of the three eccentric butterfly valve will also vary greatly, and the applicable temperature and pressure rating range of the three eccentric butterfly valve is incomparable to other types of butterfly valves.
