    Cast Iron Pinless Wafer Butterfly Valve 1.0/1.6 Mpa Pressure Handle Power

    Cast Iron Handle Power Pin-Less 1.0/1.6 Mpa Pressure Wafer Butterfly Valve


    Introduction

    The butterfly plate of wafer butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis with a rotation angle of 0 ° - 90 °, which can play the role of flow regulation. When the butterfly plate rotates to 90 °, the valve reaches the maximum opening. The wafer butterfly valve has the advantages of simple structure, small volume and light weight. It is only composed of a few parts. Moreover, it can be opened and closed quickly by rotating 90 °, which is simple to operate. At the same time, the valve has good fluid control characteristics.


    performance comparison


    Which of ordinary butterfly valve and gate valve with the same nominal pressure and nominal diameter has better tightness and is not easy to leak?

    The tightness of gate valve is better than that of butterfly valve, but some manufacturers have good sealing performance of butterfly valve.

    The gate valve has large volume and occupies large space.

    The butterfly valve has small volume and small space.

    The specific selection should also consider the temperature of the medium, the sealing and packing of the valve.

    Butterfly valves with nominal diameter greater than 50 are specified in the specification.

    The high-performance manual butterfly valve adopts a double eccentric and a special inclined cone elliptical sealing structure. The utility model solves the disadvantage that the sealing surface of the traditional eccentric butterfly valve is still in sliding contact friction at the moment of opening and closing 0 ° ~ 10 °, realizes the effect that the sealing surface of the butterfly plate is separated at the moment of opening, and the sealing effect is closed at the moment of closing contact, so as to prolong the service life and achieve the best sealing performance.
