Introduction

The handle 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. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body. Therefore, the pressure drop generated through the valve is very small, so it has good flow control characteristics

performance

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 the gate valve is better than that of the butterfly valve, but some manufacturers' butterfly valves have good sealing performance.

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.

Handle butterfly valve is a national key new product. 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.
