Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. a groove-shaped hoop; 2. a spring; 3. a spring washer; 4. a Y-shaped seal ring; 5. a connector head a; 6. a connecting pipe head b; 7. the anticreep piece.
Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the specific drawings.
Fig. 1 is the utility model discloses a novel bury ground gas pipeline interface connection device, as shown in the figure, a novel bury ground gas pipeline interface connection device, including pipe connector head, cell type clamp 1, spring 2, spring shim 3 and Y type rubber seal 4, wherein:
the pipeline connecting pipe head comprises two parts, namely a connecting pipe head a5 and a connecting pipe head b6, the inner side of the groove-type clamp 1 clamps the connecting pipe head a5 and the connecting pipe head b6, and a certain horizontal distance is reserved between the connecting pipe head a5 and the connecting pipe head b6, the connecting pipe head a5 and the connecting pipe head b6 are integrally provided with anti-falling blocks 7 corresponding to the inner side grooves of the groove-type clamp 1, the connecting pipe head a5 and the connecting pipe head b6 are prevented from falling off in the groove-type clamp 1, and the connecting pipe head a5 and the connecting pipe head b6 can have certain horizontal displacement in the groove-type clamp 1, so that the telescopic purpose is;
be equipped with spring 2 between the lateral wall of anticreep piece 7 and cell type clamp 1, 2 rings of spring set up in cell type clamp 1 inner one side, and 2 one ends of spring are connected with cell type clamp 1 inboard, and the other end is connected with spring shim 3, and spring shim 3 keeps away from 2 one side of spring and installs Y type rubber seal 4.
In this embodiment, the two ends of the connector head a5 and the connector head b6 are both provided with flanges with threads, so that the connectors can be connected with common pipelines through threads.
In this embodiment, Y type rubber seal 4 is the horizontal structure of placing of Y shape, and Y type rubber seal 4 hoop sets up in cell type clamp 1.
