It is interior, and the outer wall of sealing ring is in outer male structure, the inner wall of sealing ring is in concave inward structure.
By using above-mentioned technical proposal, seal assembly is equipped between valve rod and valve body, seal assembly includes being set to valve
Two outer grooves on bar outer wall, two inner grooves for being set to valve interior wall and being oppositely arranged with two outer grooves and it is set to outer ring
Sealing ring in slot so that inside and outside ring groove shape is at an installation chamber, and is set in installation cavity room by the inside and outside annular groove of setting
Sealing ring is set, and by the ratio between the groove depth of outer groove and the groove depth of inner groove between 5-6, so that the side of sealing ring
It is placed in outer groove, the another of sealing ring is placed in inner groove, by the cooperation between sealing ring and installation chamber, increases
The area of sealing, while preventing sealing ring there is a phenomenon where misplacing, and be in outer male structure by the outer wall of sealing ring, sealing ring
Inner wall is in concave inward structure, so that the inner wall concave inward structure of sealing ring has covered effect, and then ensures in outer male structure stress
Good sealing effect.
The utility model is further arranged to: the seal assembly further includes the retaining ring being set on valve rod and is set to
Limited ring groove on valve body, retaining ring are placed in limited ring groove, and inconsistent with limited ring groove.
By using above-mentioned technical proposal, seal assembly further includes the retaining ring being set on valve rod and is set on valve body
Limited ring groove, retaining ring is placed in limited ring groove, and inconsistent with limited ring groove, and the failure sealed in order to prevent then passes through gear
Cooperation between circle and limited ring groove is to improve the sealing effect between valve rod and valve body.
The utility model is further arranged to: the valve rod is additionally provided with body, and body is placed on outside valve rod, and body is placed in gear
On circle, body side and retaining ring are inconsistent, and the another of body is placed in limited ring groove.
By using above-mentioned technical proposal, valve rod is additionally provided with body, and body is placed on outside valve rod, and body is placed on retaining ring,
It is arranged by using above structure, by the body of setting, keeps one side inconsistent with retaining ring, the another of body is placed on limit
In annular groove, then good sealing effect between valve body and valve rod is improved.
The utility model is further arranged to: the side side that the body and limited ring groove contradict is equipped with several absorption
Hole.
By using above-mentioned technical proposal, the side side that body and limited ring groove contradict is equipped with several adsorption holes, leads to
It crosses and is equipped with several adsorption holes on the side side that body and limited ring groove contradict, so that body forms absorption in limited ring groove
Effect, because valve rod and valve body there is no relative position in-between, are then only needed by the way that rotated to valve rod can be into
Row is through-flow, therefore can then improve the adsorption effect between body and limited ring groove by the way that adsorption hole is arranged, and improves leakproofness, cooperation
Seal assembly between valve rod and valve body forms dual sealing effect.
Detailed description of the invention
Fig. 1 is a kind of cross-sectional view of anti-seal failure long-life gas valve embodiment of the utility model.
Fig. 2 is structure amplification signal at A in a kind of Fig. 1 of anti-seal failure long-life gas valve embodiment of the utility model
Figure.
Specific embodiment
A kind of anti-seal failure long-life gas valve embodiment of the utility model is described further referring to figs. 1 to Fig. 2.
A kind of anti-seal failure long-life gas valve, connect including valve body 1, the valve ball being set in valve body 12, with valve ball 2
Valve rod 3 and the handwheel 5 that is connect with valve rod 3, seal assembly is equipped between valve rod 3 and valve body 1, seal assembly includes being set to
Two outer grooves 30 on 3 outer wall of valve rod, two inner grooves 10 for being set to 1 inner wall of valve body and being oppositely arranged with two outer grooves 30 and
The sealing ring 4 being set in outer groove 30, by the inside and outside annular groove of setting, so that inside and outside ring groove shape is at an installation chamber, and
