Arc opening direction is backwards to valve ball so that is above set between sealing ring and lower seal formed with Support using said structure
Support so that when suppression occurs, even if lower seal stress, also have sealing ring and a reaction is formed to it
Power, so as to reach good sealing effectiveness, and convex structure has more good resilient support effect, and lower seal
Circular arc opening direction towards opposite with the circular arc opening direction of upper sealing ring so that during installation, lower seal is not
The installation of valve rod can be hindered, and upper sealing ring includes upper resistance surface, and lower seal includes lower resistance surface, and upper resistance surface is with placing
The side side wall of annular groove is inconsistent, and lower resistance surface and the opposite side side wall for placing annular groove are inconsistent, then further improve upper and lower close
Being completely embedded property between seal and placement annular groove.
The utility model is further arranged to：The bonnet is provided with the first spacing back-up ring and the second spacing back-up ring, and first
Formed with limited ring groove between spacing back-up ring and the second spacing back-up ring, limited ring groove is interior to be provided with flexible sealing gasket.
By using above-mentioned technical proposal, bonnet is provided with the first spacing back-up ring and the second spacing back-up ring, passes through setting
First spacing back-up ring and the second spacing back-up ring so that formed with limited ring groove between the first spacing back-up ring and the second spacing back-up ring,
And flexible sealing gasket is provided with limited ring groove so that the sealing effectiveness between bonnet and hexagonal nuts is improved, with
And both elastic effects when being attached are improved, when outer jointed tubular workpieces are attached, external pipe fitting carries out stress to sealing gasket,
Because sealing gasket is flexible, sealing gasket can carry out a reaction force by external jointed tubular workpieces while stress, so as to further
The connective stability improved between hexagonal nuts and external pipe fitting.
The utility model is further arranged to：The Support is in " () " shape.
By using above-mentioned technical proposal, Support is in " () " shape, by the way that Support is arranged into said structure so that on
The both ends of lower two sealing rings can mutually contradict, and ensure that can ensure good support effect between the two, so as to reduce
The degree deformed upon during stress, and then ensure that good sealing effectiveness.
Brief description of the drawings
Fig. 1 is a kind of cross section structure diagram of Integrated ball valve embodiment of the utility model.
Fig. 2 is the partial structurtes enlarged diagram at A in Fig. 1.
Embodiment
A kind of Integrated ball valve embodiment of the utility model is described further referring to figs. 1 to Fig. 2.
A kind of Integrated ball valve, including ball valve body, ball valve body include valve body 1, bonnet 2 and be connected with bonnet 2 six
