Double eccentricity electric butterfly valve structure features
Posted on

Double eccentric electric butterfly valve is a kind of electric valve and electric control valve. The main connection methods are: flange type and wafer type. It is an important execution unit in the field of industrial automation control. It is widely used in the water supply and drainage of waterworks, power plants, steel mills, papermaking, chemical industry, etc., as adjustment and cut-off use.

Double eccentric electric butterfly valve structure features:

1、Electric double eccentric butterfly valve adopts double eccentric structure, with more tight sealing function, reliable sealing performance;

2. The sealing pairing material is made of stainless steel and nitrile rubber resistant rubber pair, which has long service life;

3, rubber seal ring can be located on the valve body, can also be located on the butterfly board, can apply different characteristics of the media for users to choose;

4. The butterfly plate adopts frame structure, high strength, large flow area, small flow resistance; 5, the overall paint, can effectively prevent corrosion and as long as the replacement of the sealing valve seat sealing material, can be used for different media;

6, the valve has a two-way sealing function, the installation is not controlled by the flow of the media, but also by the location of space, can be installed in any direction;

7, the valve structure is unique, flexible operation, effort, and convenience.

Angular Contact Ball Bearings have inner and outer ring raceways that are displaced relative to each other in the direction of the bearing axis. This means that these bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.


The axial load carrying capacity of angular contact Ball Bearings increases as the contact angle increases. The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the combined load is transmitted from one raceway to another, and a line perpendicular to the bearing axis.


The most commonly used designs are:

single row angular contact ball bearings 
double row angular contact ball bearings 
four-point contact ball bearings
