electric half of an eccentric valve working principle/electric half of an eccentric valve applied occasion

1, the working principle of the electric half of an eccentric valve

the combination of electric actuators and half of an eccentric valve collectively known as electric half of an eccentric valve.

electric eccentric ball valve is by rotary valve chain to make the valve opened or closed. Ball valve switch lightweight, small size, can make it big caliber, reliable sealing, simple structure, convenient maintenance, sealing surface and the spherical often in the closed state, not easily be medium erosion, has been widely used in various industries.

electric half of an eccentric valve opening and closing without friction. This function completely solve the traditional [ Friction between the Industrial Valves for sealing surface and affect the sealing problem. Jacket type structure. The valve can be directly mounted on the pipeline online inspection and maintenance, can effectively reduce the parking device, reduce the cost. Single seat design. To eliminate the influence due to abnormal pressure valve lumen medium use safety problems. Low torque design. Special structure design of the valve stem, only with a small hand could easily open/close the valve. The structure of sealing wedge. by valve stem provides mechanical force, wedge pressure the ball into the seat and seal, make the valve's sealing is not affected by changes in the pipeline pressure difference, under various conditions sealed performance has a reliable guarantee. Since the clean structure of the sealing surface. When ball tilting away from the seat, fluid in the pipeline along the sphere seal face into 360 & deg; Even through, not only eliminates the high velocity on the seat of local scour, also washed away by the accumulated on the surface of the sealing material, achieve the goal of the clean.

electric eccentric ball valve fluid resistance small, its resistance coefficient with section of equal length. Simple structure, small volume, light weight. Compact and reliable, the widespread use of plastic ball valve sealing surface of materials, good sealing, also has been widely used in the vacuum system. Easy to operate, open and close quickly, from open to close just rotate it 90 & deg; To facilitate remote control. Convenient maintenance, simple structure of ball Industrial Valves, sealing ring, which generally remove replacement is more convenient. In full open or full close, sphere and valve seat sealing surface and the dielectric isolation, medium through, does not cause the valve sealing surface erosion. Applicability is wide and size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied.

2, electric half of an eccentric valve applied occasion

electric eccentric half ball valve is suitable for wastewater treatment, pulp, alumina, city heating heating to the tightness of occasions; Apply to power plant, the control of hydraulic slag or gas pipelines.

electric half of an eccentric valve on the appearance of the structure is divided into two kinds:

1, the jacket type: mainly aims at the medium of erosion wear is very serious, jacket structure in damaged open-close part replacement maintenance is very convenient, don't need the whole valve from the pipeline will be removed, greatly save the maintenance time and cost.

2, side mounted, side mounted light valve quality and compact structure, suitable for the valve installation space with the requirements of the occasion.
