Description
Technical field
This utility model belongs to universal machine field, is related to pipe collar used in a kind of tubing with pressure.
Background technology
In prior art, carry in the tubing of pressure in steam, compressed air etc., when needing that pipeline is keeped in repair
Or during part in replacing pipeline, need to close the valve of upper level, lay down the pressure in pipeline and could keep in repair or change.And
In order to safer and quickly lay down pressure in pipeline, also it is the convenience ensureing maintenance simultaneously, often needs in the duct
Numerous pressure release arms and valve are set, to meet the needs of the stable and maintenance of pressure in main pipeline, thus unavoidably
Increase equipment investment and maintenance workload.And in real work, and not all pipeline is suitable for installing relief pipeline,
As be just not suitable for before pressure gauge installing relief pipeline, when needing to change pressure gauge, although it closes the valve before pressure gauge,
But still possess higher pressure medium in the pipeline between valve and pressure gauge, now will dismounting pressure gauge with pressure, have one
Fixed potential safety hazard.Thus it is directed to these defects, develop new, safer pressure relief device and still there is highly important answering
Use meaning.
Content of the invention
This utility model purpose is to provide a kind of new screw thread pipe collar with relief hole, consequently facilitating pipeline with pressure is applied
Work is applied.
Details are as follows for the technical scheme that the application is taken.
A kind of screw thread pipe collar with relief hole, sets female pipe collar and the band being respectively arranged on pipe collar two ends including one
First short circuit of end face and the second short circuit；
It is provided with pressure relief vent, in decision design, pipe collar is hexahedron pipe collar in the middle part of the side wall of described pipe collar；
Described first short circuit includes, the first linkage section for connecting pipe of being sequentially connected (using threaded or
Flange connects), the first connecting end surface be connected with pipe collar the first external screw thread, seal set by the first male threaded end
Interior bone within boss and the first short circuit；First linkage section and the first external screw thread connected by first end face formed one whole
Body；
Described second short circuit includes, the second linkage section for connecting pipe of being sequentially connected (using threaded or
Flange connects), the second connecting end surface be connected with pipe collar the second external screw thread, seal set by the second male threaded end
Interior bone within groove and the second short circuit；Second linkage section and the second external screw thread connected by second end face formed one whole
Body.
The know-why of the application is, after the screw thread pipe collar with relief hole provided herein, the first short circuit
The groove of boss and the second short circuit meets at the middle part of pipe collar, has preferable sealing function it is ensured that pressure in pipeline with pressure
Stable；And when needing release, after closing higher level's valve, somewhat loosen the first short circuit or the second short circuit so that boss and groove
Between sealing function release, the pressure medium in pipeline with pressure can pressure relief vent on pipe collar be discharged, and lays down pipeline intrinsic pressure
Power.Because the reliability now by threaded pipeline does not reduce, thus now there is not security hidden trouble, can be relatively
For convenient and quick, conduit component is repaired or replaced.
In general, this utility model is applied to the nontoxic band hydraulic pipe application such as compressed air, steam, tool
There is simple, easy to use, the non-maintaining advantage of structure；During use, can safer, conveniently lay down pipeline with pressure system
In pressure, eliminate with pressure dismounting when potential safety hazard, improve tubing maintenance when safety, simultaneously improve tubing
Maintenance efficiency and reduce tubing maintenance cost.
Brief description
Fig. 1 is the structural representation of the screw thread pipe collar with relief hole provided by the utility model.
Specific embodiment
Below in conjunction with the accompanying drawings explanation is further explained to the application.
Embodiment
A kind of screw thread pipe collar with relief hole, sets female pipe collar 2 including one and is respectively arranged on pipe collar 2 two ends
The first short circuit with end face and the second short circuit；
It is provided with pressure relief vent 7, pipe collar 2 is preferably hexahedron pipe collar in the middle part of the side wall of described pipe collar 2；
First short circuit includes, and employs external screw thread shown in the first linkage section 4(in figure for connecting pipe being sequentially connected
Connect, may also be employed flange connect or other connected modes), the first connecting end surface 1 be connected with pipe collar 2 the first external screw thread 5,
Interior bone 11 within the boss 6 sealing of the first external screw thread 5 end and the first short circuit；First linkage section 4 and
One external screw thread 5 is connected by first end face 1 and forms an entirety；
Second short circuit includes, and employs outer spiral shell shown in the second linkage section 10(in figure for connecting pipe being sequentially connected
Stricture of vagina connects, and flange may also be employed and connect or other connected modes), the second external screw thread of being connected with pipe collar 2 of the second connecting end surface 3
9th, the interior bone 11 within the groove 8 sealing set by the second external screw thread 9 end and the second short circuit；Second linkage section 10
Connected by second end face 3 with the second external screw thread 9 and form an entirety.
When specifically used, when the screw thread pipe collar with relief hole provided by the utility model is accessed pipeline with pressure system,
Second linkage section 10 of the first linkage section 4 of the first short circuit and the second short circuit is connected with pipeline with pressure system and keeps not leaking.
And the first external screw thread 5 and the second external screw thread 9 screw in pipe collar 2 respectively, at the middle part of pipe collar 2, the boss 6 sealing and recessed
Groove 8 here is met, and in the presence of pretightning force, forms linear sealing, thus ensureing pipeline with pressure between seal boss 6 and groove 8
Interior pressure medium does not leak (due to being linear sealing it is not necessary to too big pretightning force just can reach good sealing effectiveness).
When needing to lay down pipeline with pressure internal pressure, after closing higher level's valve, somewhat loosen the first short circuit or second short
Connect, so that the sealing relationship between boss 6 and groove 7 is released, now the pressure medium in pipeline can be discharged from pressure relief vent 7,
So that the pressure in pipeline with pressure is laid down, now can be safer and quick pipeline with pressure system is safeguarded.
It should be noted that during release, as long as somewhat loosening between the first short circuit or the second short circuit and pipe collar 2, due to
Now there is not significant change in threaded intensity, thus the process of this loosening release is that there is not potential safety hazard,
It is safer reliable.
