Abstract
The utility model discloses a kind of flange, including flange body and the bolt of connection two flange body, described flange body is provided centrally with pipe receiving hole, it is characterised in that described flange body has joint face；Along first seal groove that is circumferentially provided with of pipe receiving hole on described joint face, described first seal groove is from the described outward extending inclined-plane of pipe receiving hole, is equiped with delta-ring in described first seal groove, and the cross section of described delta-ring is right angled triangle；Described joint face arranges the second seal groove near marginal position, and described second seal groove is groove, is provided with zigzag sealing ring in described second seal groove.This utility model uses delta-ring and zigzag sealing ring, makes the sealing property between flange body joint face higher.
Description
Technical field
This utility model relates to connection member technical field, is specially a kind of flange.
Background technology
Flange is generally welded on the circumference of tube end pipe, valve and axle to be linked together, and connects respectively
Pipe is had to be bolted to connection together, it is ensured that after connecting between pipe, the liquid of circulation is non-leakage, the two of Flange joint
Sealing between individual flange plays critical effect.
Summary of the invention
This utility model is for the proposition of problem above, and the flange of a kind of favorable sealing property of research design.
Technological means of the present utility model is as follows:
A kind of flange, including flange body and the bolt of connection two flange body, described flange body is provided centrally with pipe
Receiving hole, it is characterised in that described flange body has joint face；It is circumferentially provided with along pipe receiving hole on described joint face
One seal groove, described first seal groove is from the described outward extending inclined-plane of pipe receiving hole, is equiped with in described first seal groove
Delta-ring, the cross section of described delta-ring is right angled triangle；Described joint face arranges near marginal position
Two seal grooves, described second seal groove is groove, is provided with zigzag sealing ring in described second seal groove.
Further, when two flange body connect, the zigzag sealing ring in two flange body is mutually clamped.
Compared with the prior art, the beneficial effect of flange described in the utility model: delta-ring is by the pipe at two ends
Sub-interface seals, and the zigzag sealing ring in two flange body is mutually clamped, it is ensured that seals between sealing ring and more fits.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present application or technical scheme of the prior art, below will be to embodiment or existing
In having technology to describe, the required accompanying drawing used is briefly described, it should be apparent that, the accompanying drawing in describing below is only this
Some embodiments described in application, for those of ordinary skill in the art, on the premise of not paying creative work,
Other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is this utility model embodiment flange body front view；
Fig. 2 is A-A sectional view in Fig. 1；
Fig. 3 is Flange joint exploded perspective view.
In figure: 1, flange body, the 11, first seal groove, the 12, second seal groove, 13, pipe receiving hole, 14, joint face, 3,
Delta-ring, 5, zigzag sealing ring.
Detailed description of the invention
Flange as shown in Figure 1-Figure 3, including flange body 1, the bolt (not shown) that connects two flange body 1, flange
Body 1 center is respectively arranged with pipe receiving hole 13, and flange body 1 has joint face 14；Along pipe receiving hole 13 on joint face 14
Being circumferentially provided with the first seal groove 11, the first seal groove 11 is from the outward extending inclined-plane of pipe receiving hole 13, the first seal groove 11
Inside being equiped with delta-ring, the cross section of delta-ring is right angled triangle；Joint face 14 is arranged near marginal position
Second seal groove 12, the second seal groove 12 is groove, is provided with zigzag sealing ring in the second seal groove 12.
Specifically, in conjunction with Fig. 3, during installation, first by two tube weldings in the pipe receiving hole 13 of corresponding flange body 1
In, delta-ring is put into the first seal groove 11, the face towards pipe receiving hole 13 of delta-ring is tight with pipe
Closely connected conjunction, then loads zigzag sealing ring in the second seal groove 12, finally two flange body 1 is engaged, and makes two flanges originally
The sawtooth of the zigzag sealing ring being oppositely arranged on body 1 is mutually clamped, finally by bolt by fixing even for two flange body 1
Connect.
The above, only this utility model preferably detailed description of the invention, but protection domain of the present utility model is not
Being confined to this, any those familiar with the art is in the technical scope that this utility model discloses, according to this practicality
Novel technical scheme and inventive concept equivalent or change in addition thereof, all should contain protection domain of the present utility model it
In.
