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
