Abstract
The utility model discloses a pipe leakage detection sealing device, belonging to the exclusive leakage detection tool filed. The pipe leakage detection sealing device comprises an outer spring, an inner spring, an air inlet hole, a bucket-shaped piston, an O-shaped rubber ring, a cylinder, an inner hole air plug, an annular outer hole air plug, an inner hole air plug rubber mat, and an annular outer hole air plug rubber mat. The outer spring and the inner spring are arranged within the bucket-shaped piston and the cylinder; the outer spring acts on between the cylinder and the bucket-shaped piston; the inner spring acts on the portion between the inner hole plug and the bucket-shaped piston; an O-shaped rubber ring is positioned at the connection part of the bucket-shaped piston and the cylinder; the bottom of the bucket-shaped piston is provided with the air inlet hole; the inner hole air plug rubber mat is adhered on the inner hole air plug; the outer hole air plug rubber mat is adhered on the annular outer hole air plug; and the cylinder is integrated with the annular outer hole air plug. The leakage detection sealing device adopts double springs and performs pressure on the air plugs, which quickly seals the tube end opening, enhances the leakproofness and increases detection efficiency.
Description
Technical field
The utility model relates to a kind of pipeline leak detection packoff, belongs to the specific purpose tool field of leaking hunting.
Background technology
At present, along with automotive oil tank heating technique is constantly perfect, New Heating can heat oil pipe, but this oil pipe is set with the structure of water pipe outward, air pressure leaks hunting very loaded down with trivial details, if there is a kind of oil pipe mouth of both can having blocked also can block the instrument that is enclosed within oil pipe outside hose nozzle simultaneously, detection efficiency will improve greatly.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of simple and reasonable, easy to use pipeline leak detection packoff is provided, solves the problem existing in background technology.The technical scheme that solves its technical matters employing is: the technical scheme that solves its technical matters employing is:
1.a kind of pipeline leak detection packoff, comprise: outer spring 1, inner spring 2, air admission hole 3, tubbiness piston 4, O type cushion rubber 5, cylinder barrel 6, endoporus gas stifled 7, the outer hole of ring-type gas stifled 8, endoporus gas blocks up rubber cushion 9, the stifled rubber cushion 10 of the outer hole of ring-type gas, described outer spring, inner spring is all arranged in tubbiness piston and cylinder barrel, outer spring acts between cylinder barrel and tubbiness piston, inner spring acts on endoporus gas and blocks up between tubbiness piston, tubbiness piston and cylinder barrel junction are provided with O type cushion rubber, trunk-piston bottom is provided with air admission hole, endoporus gas blocks and is stained with the stifled rubber cushion of endoporus gas, the outer hole of ring-type gas blocks and is stained with the stifled rubber cushion of the outer hole of ring-type gas, stifled being structure as a whole of the outer hole of cylinder barrel and ring-type gas.
The beneficial effects of the utility model: on this sealing device structure that leaks hunting, adopt the dual spring stifled mode of gas of simultaneously exerting pressure, can fast sealing pipe port, strengthen sealing, improve detection efficiency.
Brief description of the drawings:
Fig. 1 is in the main TV structure sectional view of the utility model figure: 1, a kind of pipeline leak detection packoff, comprising: outer spring 1, inner spring 2, air admission hole 3, tubbiness piston 4, O type cushion rubber 5, cylinder barrel 6, endoporus gas are stifled 7, the outer hole of ring-type gas is stifled 8, the stifled rubber cushion 9 of endoporus gas, the stifled rubber cushion 10 of the outer hole of ring-type gas.
Embodiment:
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Referring to 1. 1 kinds of pipeline leak detection packoffs of accompanying drawing, comprise: outer spring 1, inner spring 2, air admission hole 3, tubbiness piston 4, O type cushion rubber 5, cylinder barrel 6, endoporus gas stifled 7, the outer hole of ring-type gas stifled 8, endoporus gas blocks up rubber cushion 9, the stifled rubber cushion 10 of the outer hole of ring-type gas, described outer spring 1, inner spring 2 is all arranged in tubbiness piston 4 and cylinder barrel 6, outer spring 1 acts between cylinder barrel 6 and tubbiness piston 4, inner spring 2 acts between endoporus gas stifled 7 and tubbiness piston 4, tubbiness piston 4 and cylinder barrel 6 junctions are provided with O type cushion rubber 5, trunk-piston 4 bottoms are provided with air admission hole 3, on endoporus gas stifled 7, be stained with the stifled rubber cushion 9 of endoporus gas, on the outer hole of ring-type gas stifled 8, be stained with the stifled rubber cushion 10 of the outer hole of ring-type gas, the outer hole of cylinder barrel 6 and ring-type gas stifled 8 is structure as a whole.
Principle of work of the present utility model is summarized as follows:
Principle of work of the present utility model is summarized as follows: first by stifled endoporus gas oil pipe port, the water pipe port of the outer hole of the ring-type stifled alignment sleeve of gas outside oil pipe aimed at, then at the piston base seal process that pressurizeed, pressurized air is through air admission hole and endoporus gas is stifled and the gap of the outer hole gas of ring-type between stifled enters and be detected in pipeline.
