The opening and closing element of angle stop valves is the spool of stopper, and sealing surface is plane or the conical surface, and spool is along the centrage of fluid
For linear motion.Angle stop valves, also known as angle valve, the forms of motion of valve rod, has elevating lever-type, i.e. valve rod lifting, handwheel does not rises
Fall；Also having lifting rotation rod-type, i.e. handwheel rotation and lifting together with valve rod, nut is located on valve body.Angle stop valves is only suitable for
In standard-sized sheet and fully closed, do not allow to make adjustments and throttle.Stop valve belongs to forced seal formula valve, so when valve closing, must
Pressure must be applied, to force the sealing surface of stop valve not leak to flap.When medium is by entrance valve below spool, operating physical force
Needed for the resistance that overcomes, be valve rod and filler frictional force with by thrust produced by the pressure of medium.
Existing angle stop valves exist sealing poor, assemble difficulty, inner part is difficult to the problems such as replacing, and for this, we set
Count split angie type metal hard-sealing stop valve.
