Groove location is symmetrical is arranged in the side of No. two flanges for envelope；It is provided with the oblique sealing surface of No.1 on the inside of No.1 sealed groove, two
It is provided with hemisphere seal on the inside of number sealed groove, the surface of hemisphere seal is provided with No. two circular arc sealing surfaces, No. two circles
Arc sealing surface and the oblique sealing surface of No.1 are connected realizes that sealing coordinates by screw bolt and nut, and nut is placed on No. two flanges
In bolt fixing hole, bolt is connected across bolt mounting holes with the nut in bolt fixing hole.
Further, the angle of the oblique sealing surface of the No.1 and flange longitudinal centre line is 30-60 degree.
Further, the diameter of the hemisphere seal of No. two flanges is not less than the oblique sealing surface maximum gauge of No.1.
Further, the left side of No. two flanges is provided with bolt fixing hole, and the bolt fixing hole is interior hexagonal spiral shell
Bolt mounting hole.
Further, the bolt mounting holes of the No.1 flange are installed for both sides semicircle bar shaped, are used for installation bolt position tune
It is whole.
The utility model has the beneficial effects that：1 is reasonable for structure, easily fabricated, at low cost；2 is highly practical, securely and reliably；3
Using mechanical face fitted seal, sealing effect is good, and service life is long, conveniently applies for the oblique sealing surface of No.1 and No. two circular arc sealing surfaces
Work.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the vertical view of the utility model.
In figure：1, No. two flange 2 of No.1 flange, gasket 3, bolt fixing hole 4, hemisphere seal 5, bolt mounting holes 6,
Location hole 7, No.1 sealed groove 11, the No.1 sealed groove 14 of circular arc sealing surface 13, two of oblique sealing surface 12, two.
Specific implementation mode
With reference to embodiment, the utility model will be further described.
A kind of compression type flange with sealing ring of the utility model is mainly by 1, No. two flange 2 of No.1 flange, sealing
Pad 3, bolt fixing hole 4, hemisphere seal 5, bolt mounting holes 6, location hole 7, No.1 sealed groove 11, the oblique sealing surface of No.1
12,13, No. two sealed grooves 14 of No. two circular arc sealing surfaces form.
As shown in Figure 1, being evenly distributed with bolt mounting holes 6 on the No.1 flange 1, it is arranged in the side of No.1 flange 1
There is No.1 sealed groove 11, form a seal groove between No.1 sealed groove 11 and No. two sealed grooves 14, in seal groove
Gasket is installed, No. two sealed grooves 14 and 11 position of No.1 sealed groove is symmetrical is arranged in the side of No. two flanges 2；One
The inside of number sealed groove 11 is provided with the oblique sealing surface 12 of No.1, and the inside of No. two sealed grooves 14 is provided with hemisphere seal 5,
