Description
Technical field
This utility model relates to a kind of fluid control valve, particularly to a kind of heavy caliber double containment function ball valve.
Background technology
Ordinary ball valve (ball valve), defined in standard GB/T21465-2008 " valve term " be: opening and closing element (ball
Body) driven by valve rod, and the valve rotated around ball valve axis.Also can be used for regulation and the control of fluid, the closeest
Envelope has the strongest shearing force between V-type ball valve its V-type core and metal seat valve of pile-up welding hard alloy, is particularly well-suited to containing fibre
The medium of dimension, small solid material etc..And multi-pass ball valve not only can control the interflow of medium, shunting and stream on pipeline flexibly
To switching, simultaneously also can close arbitrary passage and make two other passage be connected.This class valve the most typically should water
Safety fills.Ball valve is divided into according to type of drive: pneumatic ball valve, electrical ball valve, manual ball valve.Ball valve is mainly used to do in pipeline
Cutting off, distribute and change the flow direction of medium, it has only to the operation with 90-degree rotation and the least rotating torque just can be closed
Close tight.Ball valve optimum switchs, stop valve uses, V-type ball valve.Electrically operated valve except it should be noted that in addition to pipe parameter, Shang Yingte
Not noting its environmental condition used, owing to the electric device in electrically operated valve is an electromechanical equipment, its use state is made by it
Very big with environmental effect, easily producing expands with heat and contract with cold causes sealing contraction, causes leakage phenomenon.
Existing ordinary ball valve is then full-gear, and its simple in construction, lightweight, conveniently opening and closing is rapid, fluid resistance is little
Advantage, but to use be changeless to its core sealing ring of existing ball valve, during installation, easily produces sealing surface easily by squeezing
Pressure, deforms, causes core not closed, and causes big-diameter ball valve leakage rate big, wastes water source, and changes the most not side
Just, making troubles and lose to production and workmen, range has been subject to great restriction.

Mouth and water outlet, be provided with compression spring, sealing ring between described active ring and ball-type spool, described compression spring is located at activity
Between circle and sealing ring, described sealing ring fits tightly with ball-type spool, its operation principle: when on this novel pipe laying,
Pipe flange end face and this ball valve flange face are fitted and compress active ring, and at this moment active ring pushes compression spring and makes sealing ring
Fitted tightly to ball-type spool by certain elastic force, it is ensured that sealing surface can maintain original sealing property, and therefore sealing ring exists
More will not produce crimp under the effect of elastic force, and sealing property is the best, open and close moment lighter, substantially increase ball valve
Sealing property and the advantage increased the service life, freedom from repairs, more do not result in a large amount of water waste, obtained wide when coming into operation
The accreditation of large user.
Described sealing ring sealing surface use the conical surface design, it is possible to ensure close ball valve time close tighter and tighter, described water inlet with
Outlet is respectively provided with two steady pins, prevents active ring from dropping out, and more convenient moves in loose slot.
