Import ball valve working principle
The United States of America Ou electric ball valve rotary valve works by love to make the valve flow or occlusion. Valve switch light, small size, can be made into a great caliber, sealed and reliable, simple structure, convenient repair, sealing surface and spherical often in closed state, can not easily be medium erosion, in all sectors is widely used. Import ball valve and plug valves are the same types of valves, closure of the only pieces of it is a sphere, the sphere around the center line as a rotary valve to achieve the open, the closure of a valve. Import ball valve in the pipeline is mainly used to make cutting, distribution and change the direction of the flow medium. Ball valve is widely used in recent years a new type of valve.
Import ball valve main advantages
1 fluid resistance is small, the drag coefficient with the same length of pipe equal.
2has the advantages of simple structure, small volume, light weight.
3closely reliable, valve sealing surface material is currently widely used in plastic, sealing well, in the vacuum system has also been widely used.
4 the operation is convenient, rapid opening and closing, from full-to full-clearance as long as the rotation of 90°, to facilitate remote control.
5ball valve has the advantages of simple structure, convenient repair, seals are generally activities, the removal of the replacement is more convenient.
6 in the fully open or fully closed, ball and valve seat sealing surface and the dielectric isolation, through the media, will not cause erosion of the valve sealing surface.
7applicable to a wide range of sizes, from small to several millimetres, a few meters from the large, high pressure can be high vacuum applications.
