Abstract

The utility model discloses a flange high in sealing performance. The flange comprises a first flange and a second flange. The first flange comprises a first flange body, a pipe placement hole, a plurality of first installing holes, a first threaded pipe and a sealing piece, wherein the pipe placement hole is communicated with a middle position of the first flange body, the plurality of first installing holes are communicated with the first flange body and formed at the edge of the placement hole, the first threaded pipe is arranged at one end of the placement hole, and the sealing piece is arranged between the installing holes and the threaded pipe and protrude out of the first flange body. The second flange comprises a second flange body, a pipe placement hole, a plurality of second installing holes, a second threaded pipe and a sealing groove, wherein the pipe placement hole is communicated with a middle position of the second flange body, the plurality of second installing holes are communicated with the second flange body and formed opposite to the first installing holes respectively, the second threaded pipe is arranged on the inner wall of the pipe placement hole and is opposite to the first threaded pipe, and the sealing groove is opposite to the sealing piece. According to the flange high in sealing performance, the outer sides of the threaded pipes are provided with embedded sealing structures and accordingly the sealing performance is enhanced, the structure is simple, the manufacturing is easy, and the cost is low.

Description

High leak tightness flange
Technical field
A flange, particularly a kind of high leak tightness flange.
Background technique
In prior art, flange is widely used in mechanical field as link.By a pair of flange of working in coordination, pipeline well can be connected.As a rule, between a pair of flange plate, be by corresponding mounting hole is set, and then by realizing connection each other such as links such as bolts.But obvious this connection can not seal completely.Gap between two flange plates, easily causes leakage.Also there is recently product to expect using the elastic components such as rubber to do Sealing, but can not there is very high sealing.
Model utility content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of flange of high leak tightness.
In order to realize above-mentioned target, the utility model adopts following technological scheme:
High leak tightness flange, comprising: the first flange and the second flange; The first flange comprises: the first flange body, pipeline putting hole through the first flange body neutral position, through the first flange body and be placed in a plurality of first mounting holes at putting hole edge, be located at first threaded pipe of putting hole one end, be located between mounting hole and threaded pipe and protrude from the diaphragm seal of the first flange body; The second flange comprises: the second flange body, through the pipeline putting hole in the second flange body neutral position, through the second flange body the second mounting hole of arranging with respect to the first mounting hole; Be placed in pipeline putting hole inwall and with respect to the second threaded pipe of the first threaded pipe, with respect to the seal groove of diaphragm seal.
Aforesaid high leak tightness flange, the size of diaphragm seal is greater than the size of seal groove.
Aforesaid high leak tightness flange, diaphragm seal is sheet rubber.
Aforesaid high leak tightness flange, the first threaded pipe is male-pipe.
Aforesaid high leak tightness flange, the second threaded pipe is the riffled tube corresponding to the first threaded pipe.
Usefulness of the present utility model is: the arranged outside at threaded pipe has embedded sealing configuration to strengthen sealing.
Accompanying drawing explanation
Fig. 1 is a kind of embodiment's of the present utility model sectional view;
The implication of reference character in figure:
1 first flange, 2 second flanges, 3 pipeline putting holes, 4 first mounting holes, 5 second mounting holes, 6 first threaded pipes, 7 second threaded pipes, 8 Sealings, 9 seal grooves.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
High leak tightness flange, comprising: the first flange 1 and the second flange 2; The first flange 1 comprises: the first flange 1 body, pipeline putting hole 3 through the first flange 1 body neutral position, through the first flange 1 body and be placed in a plurality of first mounting holes 4 at putting hole edge, be located at first threaded pipe 6 of putting hole one end, be located between mounting hole and threaded pipe and protrude from the diaphragm seal of the first flange 1 body; The second flange 2 comprises: the second flange 2 bodies, through the pipeline putting hole 3 in the second flange 2 body neutral positions, through the second flange 2 bodies the second mounting hole 5 of arranging with respect to the first mounting hole 4; Be placed in pipeline putting hole 3 inwalls and with respect to the second threaded pipe 7 of the first threaded pipe 6, with respect to the seal groove 9 of diaphragm seal.It should be noted that, for convenient, produce, and sealing is good, the first threaded pipe 6 is male-pipe, and the second threaded pipe 7 is the riffled tube corresponding to the first threaded pipe 6.
In the outside of threaded pipe, be provided with again embedded sealing configuration and strengthened sealing, in order further to strengthen sealing, the size of diaphragm seal is greater than the size of seal groove 9; As a kind of preferred, diaphragm seal is sheet rubber, and diaphragm seal is so long as elastomer seal 8 is all operable in fact.
Arranged outside at threaded pipe has embedded sealing configuration to strengthen sealing, not only simple in structure, and easily makes, and cost is low.
More than show and described basic principle of the present utility model, major character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technological scheme that the mode of equivalent transformation obtains, all drops in protection domain of the present utility model.
