Description
Technical field
The utility model belongs to valve technology field, refers in particular to a kind of right angle ball valve.
Background technology
For existing right angle ball valve because water outlet aperture is fixed, connecting the pipeline of different bores needs external connector, logical
In the case of flowing water under high pressure, external connector is with valve body right angle easily because sealing problem is revealed.
The content of the invention
The purpose of this utility model is to provide a kind of right angle ball valve, better tightness between extension tube attached and valve body, reduces
The generation of seepage, it is suitable for the occasion of water under high pressure.
What the purpose of this utility model was realized in：A kind of right angle ball valve, including valve body, valve body are provided with vertical and phase
Intercommunicated water inlet and delivery port, water inlet and delivery port intersection be provided with for mounting ball valve valve element chamber, it is described go out
Mouth of a river coaxial cooperation has extension tube attached, and external pipe outer wall is provided with outer annular protrusion, hex nut, hex nut are arranged with extension tube attached
It is raised that inwall is provided with annular；Hex nut is connected with delivery port outer wall thread, and annular is raised to be contradicted outside outer annular protrusion
End face simultaneously extrudes extension tube attached towards delivery port direction in the case where screw thread screws power effect；The external tube head is provided with and stretches into water outlet
Intraoral dip section, dip section endoporus are the bellmouth become larger towards water outlet aperture.
Preferably, chamfered transition between the outer annular protrusion and dip section, the delivery port inwall and delivery port outer end
Surface chamfer transition.
Preferably, the delivery port inwall is provided with annular flange, and annular flange is provided with sealing towards the outer face of dip section
Ring recess.
Preferably, the annular flange forms with valve body casting.
Preferably, the inner face of the annular flange is ramp structure.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that：
1st, the utility model carries out gluing, sealing using dip section and delivery port inwall, extends seal length, and taper
Structure causes impact of the current to extension tube attached to reduce, and ensure that effective cooperation of extension tube attached and valve body.
2nd, the structure of chamfered transition realizes inclined-plane sealing, and longer seal length is realized compared to linear sealing.
3rd, installation sealing ring in seal groove, stretch into g. slice header and contradict sealing ring, reduce water under high pressure into dip section with
The possibility in delivery port gap.

Embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings, referring to Fig. 1-3：
A kind of right angle ball valve, including valve body 1, valve body 1 are provided with vertical and interconnected water inlet 2 and delivery port 3, entered
The mouth of a river 2 and the intersection of delivery port 3 are provided with the chamber for mounting ball valve valve element, and the coaxial cooperation of delivery port 3 has extension tube attached 4,
The outer wall of extension tube attached 4 is provided with outer annular protrusion 5, hex nut 6 is arranged with extension tube attached 4, it is convex that the inwall of hex nut 6 is provided with annular
Play 7；Hex nut 6 is connected with delivery port outer wall thread, and annular projection 7 is contradicted in the outer face of outer annular protrusion 5 and in screw thread
Screw and extrude extension tube attached 4 towards the direction of delivery port 3 under power effect；The head of extension tube attached 4 is provided with and stretches into stretching in delivery port 3
Enter section 8, the endoporus of dip section 8 is the bellmouth become larger towards the bore of delivery port 3.
Preferably, the transition of chamfering 11 between the outer annular protrusion 5 and dip section 8, the delivery port inwall and delivery port
The transition of outer end surface chamfer 11.The two chamferings 11 should ensure that to be close together after hex nut 6 is tightened completely, two chamferings 11
Angle Yidu City be 45 °.
Preferably, the delivery port inwall is provided with annular flange 9, and annular flange 9 is provided with close towards the outer face of dip section 8
Seal groove 10.
Preferably, the annular flange 9 is integrally cast with valve body 1.The structure of integrally casting improves annular flange 9
Bonding strength, annular flange 9 herein is not easy to design too high, and it is excessive not so to easily cause water resistance.
Preferably, the inner face of the annular flange 9 is ramp structure.It is so designed that, to reduce flowing water resistance.
Above-described embodiment is only preferred embodiment of the present utility model, not limits protection model of the present utility model according to this
Enclose, therefore：All equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by protection of the present utility model
