BQ6S40F Eccentric semi-ball valve
Luck and half of an eccentric valve structure features:
1, half of an eccentric valve for the jacket type structure.Mainly aims at the medium of erosion wear is very serious, jacket structure in the damage of 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, eccentric ball valve is single seat design.To eliminate the influence due to abnormal pressure valve lumen medium use safety problems.
3, low torque design.Special structure design of the valve stem, only with a small hand could easily open/close the valve.
4, opening and closing without friction.This function completely solve the traditional valve for sealing surface friction each other and affect the sealing problem.
5, wedge seal structure.Valve 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.
6,and a half, eccentric self-cleaning structure of ball valve sealing surface.When the ball tilting away from the seat, fluid in the pipeline along the sphere uniform sealing surface into 360 ¡ã 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.
Luck and half of an eccentric valve USES:
Eccentric ball valve is a relatively new type of ball valve type, it has its own unique structure some advantages, such as switch frictionless, seal is not easy to wear and open-close torque is small.Which can reduce the distribution of the specifications of the actuator.With multi-turn electric actuators, which can realize to adjust the medium and carefully cut off.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.
