The beneficial effect of above-mentioned technical proposal is: its structure is simple, by utilizing two bayonet groups at flange-interface It will include chamber in it at flange-interface that part, which is enclosed one, if at flange-interface there are gas leakage if can be by small Hole is detected, if being measured at aperture in the presence of leaking, there is leakage at flange-interface, if the leakage that do not survey, flange-interface There is no leakages at place.
Flexible rubber layer is laid on the inner wall at the both ends of bayonet component described in above-mentioned technical proposal respectively.
The beneficial effect of above-mentioned technical proposal is: so that the better tightness with pipeline at bayonet component both ends.
The two sides of the nock of the bayonet component of one of them in above-mentioned technical proposal are respectively equipped with and another bayonet The flute profile socket that component nock two sides match, when two bayonet components are wrapped in the periphery of the flange, one of them The nock two sides of the bayonet component are respectively protruding into the flute profile socket of another bayonet component nock two sides, by the two It is tightly connected at the abutting of two sides.
The beneficial effect of above-mentioned technical proposal is: so that the junction better tightness of the two sides of two bayonet components.
The slot bottom of two flute profile sockets is respectively equipped with rubber pad in above-mentioned technical proposal.
The beneficial effect of above-mentioned technical proposal is: the junction for the two sides that can further improve two bayonet components is close Feng Xing.
Clip described in above-mentioned technical proposal is electrodeless clip.
The beneficial effect of above-mentioned technical proposal is: easy to use, locking and disassembly are faster.
Detailed description of the invention
Fig. 1 is the structure diagram of the outer device for detecting leakage of bump joint described in the utility model embodiment;
Fig. 2 is the structure diagram of bayonet component described in the utility model embodiment;
Fig. 3 is the structure diagram that two bayonet components described in the utility model embodiment connect out.
In figure: 1 bayonet component, 11 apertures, 12 flute profile sockets, 121 rubber pads, 2 clips, 3 pipelines, 4 flanges.
Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical It is novel, it is not intended to limit the scope of the utility model.
As depicted in figs. 1 and 2, the outer device for detecting leakage of a kind of bump joint, including two bayonet components and two clips 2, The bayonet component includes bayonet ontology, and the bayonet ontology is arc panel, and arc angle is 180 °, and internal diameter is equal to 4 liang of flange Chamber processing is expanded to constitute the bayonet component, the card in the outer diameter of side ducts 3, the corresponding middle part in each bayonet ontology both ends The side wall of mouth component expanded at chamber is semicircle, and it expands outer diameter of the internal diameter at chamber greater than flange 4, two bayonet components 1 nock is oppositely arranged on the periphery of flange 4 to constitute the pipe fitting that chamber is expanded at a middle part, the expansion positioned at the pipe fitting of the flange At chamber, and the both ends of the pipe fitting pass through two 2 clampings of clip respectively, and two bayonet components are clamped and make it Nock two sides seal against each other abutting, and co-axial seal is set in outside two side ducts of flange respectively at the both ends of the pipe fitting, arbitrarily Corresponding expand at chamber is equipped with the aperture 11 for running through it at the middle part of one bayonet component 1.Its structure is simple, by flange It will include chamber in it at flange-interface that interface, which is enclosed one using two bayonet components, if deposited at flange-interface It can then be detected by aperture in gas leakage, if being measured at aperture in the presence of leaking, there is leakage at flange-interface, if not The leakage of survey, then there is no leakages at flange-interface.
Flexible rubber layer is laid on the inner wall at the both ends of bayonet component 1 described in above-mentioned technical proposal respectively.So that card The better tightness with pipeline at mouth component both ends.
As shown in figure 3, the two sides of the nock of the bayonet component 1 of one of them in above-mentioned technical proposal be respectively equipped with separately The flute profile socket 12 that the one 1 nock two sides of bayonet component match, two bayonet components 1 are wrapped in the flange 4 When peripheral, the nock two sides of one of them bayonet component 1 are respectively protruding into the slot of another 1 nock two sides of the bayonet component In shape socket 12, it will be tightly connected at the abutting of the two two sides.So that the junction leakproofness of the two sides of two bayonet components is more It is good.
The slot bottom of two flute profile sockets 12 is respectively equipped with rubber pad 121 in above-mentioned technical proposal.It can further mention The junction leakproofness of the two sides of high two bayonet components.
Clip 2 described in above-mentioned technical proposal is electrodeless clip.Easy to use, locking and disassembly are faster.
