Abstract
The invention discloses a high-sealing-performance flange. The high-sealing-performance flange comprises a first flange body and a second flange body. The first flange body comprises a first flange main body, a pipeline containing hole penetrating through the middle of the first flange main body, a plurality of first installation holes which penetrate through the first flange main body and are formed in the edge of the containing hole, a first threaded pipe arranged at one end of the containing hole, and a sealing piece which is arranged between the installation holes and the threaded pipe and protrudes out of the first flange main body. The second flange body comprises a second flange main body, a pipeline containing hole penetrating through the middle of the second flange main body, second installation holes which penetrate through the second flange main body and are formed corresponding to the first installation holes, a second threaded pipe which is arranged on the inner wall of the pipeline containing hole and corresponds to the first threaded pipe, and a sealing groove corresponding to the sealing piece. Embedded sealing structures are arranged outside the threaded pipes so that the sealing performance can be enhanced, and the high-sealing-performance flange is not only simple in structure but also easy to manufacture and low in cost.
Description
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.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of flange of high leak tightness.
In order to realize above-mentioned target, the present invention 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 invention 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 invention 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 present invention 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 invention, major character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technological scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
