Abstract
The utility model discloses a kind of all-welded ball valves, including valve body and the sphere being arranged in valve body, the upper and lower ends of the sphere are respectively arranged with upper valve rod and lower valve rod, it is provided with operating mechanism on the upside of the valve body, the both sides that the valve body corresponds to sphere are respectively arranged with and the matched valve seat of the sphere, the bottom surface of the valve seat is provided with inner ring flange collar, be provided on the valve interior wall with the matched annular groove of inner ring flange collar, be provided with sealing ring at the inner ring flange collar and annular groove cooperation；It is cased with disc spring outside the inner ring flange collar, the disc spring both ends are connected on the bottom surface and valve interior wall of valve seat respectively.The leakproofness of valve seat is compensated by disc spring, while inner ring flange collar can prevent disc spring directly and media contact, prevents the damage of corrosion, enhance the sealing performance of valve seat and sphere, and use is more permanent.
Description
Technical field
The utility model is related to valve field, specifically a kind of all-welded ball valve.
Background technology
All-welded ball valve, including valve body and the sphere that is arranged in valve body, the upper and lower ends of the sphere are respectively set
There are upper valve rod and lower valve rod, operating mechanism is provided on the upside of the valve body, the both sides that the valve body corresponds to sphere are respectively set
Have and be set on valve interior wall with the matched valve seat of the sphere, the valve seat, but during the use of valve, valve seat needs
The leakproofness that for a long time and sphere friction, be easy to cause valve seat and valve body is insufficient, so as to cause the generation of leakage accident.
Invention content
The purpose of this utility model：In order to overcome the deficiencies of existing technologies, the utility model provides a kind of sealing performance
Good all-welded ball valve.
The technical solution of the utility model：Including valve body and the sphere being arranged in valve body, up and down the two of the sphere
End is respectively arranged with upper valve rod and lower valve rod, operating mechanism is provided on the upside of the valve body, the valve body corresponds to the two of sphere
Side is respectively arranged with is provided with inner ring flange collar, the valve interior wall with the matched valve seat of the sphere, the bottom surface of the valve seat
On be provided with the matched annular groove of inner ring flange collar, be provided with sealing ring at the inner ring flange collar and annular groove cooperation；The inner ring
It is cased with disc spring outside flange collar, the disc spring both ends are connected on the bottom surface and valve interior wall of valve seat respectively.
Using above-mentioned technical proposal, the leakproofness of valve seat is compensated by disc spring, while inner ring flange collar can prevent
Disc spring directly and media contact, prevents the damage of corrosion, enhances the sealing performance of valve seat and sphere, and using more lengthening
Long.
The further setting of the utility model：Trim ring, the trim ring are movably set on the valve interior wall that disc spring is in contact
End face and one end of the disc spring offset, be provided with silicone gasket on the trim ring other end, the sealing ring setting
Between trim ring inner wall and inner ring flange collar outer wall.
Using above-mentioned further setting, disc spring acts on trim ring, forms the seal protection to disc spring.
The further setting of the utility model：There is gap between inner ring flange collar and annular groove bottom.
Further it is arranged using above-mentioned, gap provides the resilient movement space of valve seat.
The further setting again of the utility model：Inner ring flange collar is wholely set with valve seat, and the two internal diameter is equal.
Using above-mentioned setting further again, easy to process and installation.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model specific embodiment；
Fig. 2 is the enlarged drawing at A in the utility model Fig. 1；
Wherein, valve seat 1, valve body 2, sphere 3, upper valve rod 4, lower valve rod 5, operating mechanism 6, inner ring flange collar 11, sealing ring 12,

Specific implementation mode
A kind of all-welded ball valve as shown in Figure 1 and Figure 2, including valve body 2 and the sphere 3 that is arranged in valve body 2, it is described
The upper and lower ends of sphere 3 are respectively arranged with upper valve rod 4 and lower valve rod 5, and the upside of the valve body 2 is provided with operating mechanism 6, described
Valve body 2 correspond to sphere 3 both sides be respectively arranged with 3 matched valve seat 1 of the sphere, the bottom surface of the valve seat 1 is provided with
Inner ring flange collar 11 is provided with annular groove on 2 inner wall of the valve body, is inserted into annular groove and is coordinated with inner ring flange collar 11, it is described in
Sealing ring 12 is provided on 11 outer wall of ring convex circle, sealing ring 12 is close for will be carried out between 11 outer wall of inner ring flange collar and annular groove side wall
Envelope；It is cased with disc spring 13 outside the inner ring flange collar 11,13 both ends of the disc spring are connected to respectively in the bottom surface and valve body 2 of valve seat 1
On wall.There is gap 14 between inner ring flange collar 11 and annular groove bottom, make valve seat 1 that there is certain mobile space.Disc spring 13 can
Being in direct contact for the leakproofness of the compensation valve seat 1 of elasticity, the barrier disc spring 13 of inner ring flange collar 11 and medium, prevents corrosive medium from damaging
Disc spring 13 makes disc spring 13 keep normally acting on, extends the long-term effect of sealing function.
Separately there is embodiment, trim ring 21, one end of the trim ring 21 are movably set on 2 inner wall of valve body that disc spring 13 is in contact
Face and one end of the disc spring 13 offset, and the trim ring is provided with silicone gasket 22 on 21 other end, and sealing ring 12 is then pacified
On 11 outer wall of inner ring flange collar between 21 inner wall of trim ring and inner ring flange collar 11.Disc spring 13 presses to trim ring 21, and trim ring 21 squeezes
Pressure silicone gasket forms the seal protection to disc spring 13.
Inner ring flange collar 11 is wholely set with valve seat 1, and the two internal diameter is equal, is convenient for the processing and installation of valve seat 1.
