Between gap, be easy to cause leakage.
Chinese utility model patent application application No. is " 201520769333.0 " discloses a kind of High-sealing-performflange flange,
It is high that the utility model includes the first high-pressure water pipe flange connection gasket, the second high-pressure water pipe flange connection gasket, third
Pressure pipe flanged joint gasket, convex surface screw thread, concave surface screw thread and corrugated thread, the first high-pressure water pipe flange connection are used
Gasket is set to the second high-pressure water pipe flange connection gasket upper strata, and the third high-pressure water pipe flange connection is set to gasket
Second high-pressure water pipe flange connection gasket lower floor, the convex surface screw thread are set to the connection of first, third high-pressure water pipe flange and use
Gasket surface, the concave surface screw thread are set to the second high-pressure water pipe flange connection gasket surface, and the corrugated thread is set to
On the contact surface of first, second high-pressure water pipe flange connection gasket and flange.The utility model passes through three groups of equal point-scores of gasket
Blue pressure can realize sealing function, but since three groups of gaskets directly occur with the medium to circulate in flange to a certain extent
Contact, is easily corroded, outstanding sealing performance is not ensured that after permanent use.
Utility model content
The purpose of this utility model is to provide a kind of not welded flange of novel high sealing, to solve above-mentioned background technology
The problem of middle proposition.
To achieve the above object, the utility model provides following technical solution：A kind of not welded flange of novel high sealing,
Including first flange, second flange and gasket, the mode that is connected by screw bolts between the first flange and the second flange,
Be provided with the gasket between the first flange and the second flange, the gasket is loop configuration, and its inner ring it is upper,
Lower end is respectively fixedly connected with sealing inner ring, and the sealing inner ring covers the pipe for tapping into the first flange and the second flange respectively
Road, is also fixedly connected with the first sealing ring and the second sealing ring in arranged in co-axial alignment on the gasket, the first flange and described
Second flange is each provided with two card slots, respectively the first card slot and the second card slot, and the first card slot clamping described first is close
Seal, second card slot are clamped second sealing ring.
Preferably, the outer layer of the sealing inner ring is electroplate with anticorrosive coating.
Preferably, the axial cross section of the sealing inner ring is in " concave shape ", and its top axial section is arc-shaped.
Preferably, the thickness of first sealing ring is less than the depth of first card slot, and second sealing ring
Thickness is less than the depth of second card slot.
Compared with prior art, the beneficial effects of the utility model are：
1st, the utility model is simple in structure, easy to assembly, prevents gasket from being corroded by sealing inner ring, and pass through two groups
The stability of sealing ring one side reinforced gasket and flanged joint is easily docked, and on the other hand forms double sealing structure, is increased
The high leakproofness of flange；
2nd, the utility model is in the arc-shaped by the tip section setting that will seal inner ring, on the one hand reduces medium at two groups
On the other hand the resistance being subject in flange flow process seals inner ring and does not allow dirt easy to hang, improves its service life.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is gasket construction schematic diagram in the utility model.
In figure：1 first flange, 2 second flanges, 3 gaskets, 4 sealing inner ring, 5 first sealing rings, 6 second sealing rings, 7 the
One card slot, 8 second card slots.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
- 2 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of not welded flange of novel high sealing, packet
Include first flange 1, second flange 2 and gasket 3, the mode being connected by screw bolts between first flange 1 and second flange 2.First
Gasket 3 is provided between flange 1 and second flange 2, gasket 3 is loop configuration, and the upper and lower end of its inner ring is respectively fixedly connected with
Seal inner ring 4.Sealing inner ring 4 covers the pipeline for tapping into first flange 1 and second flange 2 respectively, and the outer layer of sealing inner ring 4 is electroplate with
