Description

Novel eccentric butterfly valve

Technical Field

The utility model relates to the technical field of butterfly valves, in particular to a novel eccentric butterfly valve.

Background

A butterfly valve, also called a flap valve, is a regulating valve with simple structure, and can be used for the on-off control of low-pressure pipeline media, namely a valve which is opened and closed by rotating around a valve shaft, wherein a closing member (a valve clack or a butterfly plate) is a disk. The valve can be used for controlling the flow of various types of fluids such as air, water, steam, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like. The pipe mainly plays a role in cutting off and throttling. The butterfly valve opening and closing piece is a disc-shaped butterfly plate and rotates around the axis of the butterfly plate in the valve body, so that the opening and closing or adjusting purpose is achieved.

The butterfly valve is a valve which uses a disc type opening and closing piece to rotate back and forth by about 90 degrees to open, close or adjust the medium flow. The butterfly valve has the advantages of simple structure, small volume, light weight, less material consumption, small installation size, small driving moment, simple and convenient operation and rapidness, and simultaneously has good flow regulation function and sealing closing characteristic, thereby being one of the fastest valve varieties developed in the last ten years. Butterfly valves are widely used.
