What is the use of the three-eccentric structure of the all-metal bidirectional butterfly valve?
The all-metal two-way pressure butterfly valve adopts a three-eccentric structure. It is completely sealed by the torque provided by the driving device. The valve can be reliably sealed under high and low pressure. That is, an angle eccentricity is added to the double eccentricity of the ordinary metal hard seal butterfly valve. The main function is: during the opening or closing of the valve, any point between the sealing ring and the valve seat will quickly disengage or contact, so as to achieve true "frictionless" between the sealing pairs, which greatly extends the valve Service life.
The valve can maintain excellent two-way sealing performance from beginning to end. The valve sealing does not rely on the force of the medium, and the sealing is completely realized by the torque provided by the driving device. The valve can be reliably sealed at high and low pressures.
