The utility model relates to a kind of pipeline leak detection packoff, belongs to the specific purpose tool field of leaking hunting.A kind of pipeline leak detection packoff, comprise: outer spring, inner spring, inner spring base, piston, O type cushion rubber, cylinder barrel, endoporus gas block up, the outer hole of ring-type gas is stifled, endoporus gas blocks up rubber cushion, the outer hole of ring-type gas blocks up rubber cushion, described outer spring, inner spring are all arranged in piston and cylinder barrel, outer spring acts between cylinder barrel and piston, inner spring acts on endoporus gas and blocks up between piston, piston and cylinder barrel junction are provided with O type cushion rubber, endoporus gas blocks and is stained with rubber cushion, the outer hole of ring-type gas blocks and is stained with rubber cushion, stifled being structure as a whole of the outer hole of cylinder barrel and ring-type gas.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.

Description

A kind of pipeline leak detection packoff
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 pipeline leak detection packoff, comprise: outer spring 1, inner spring 2, inner spring base 3, 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, it is characterized in that, described outer spring, inner spring is all arranged in piston and cylinder barrel, outer spring acts between cylinder barrel and piston, inner spring acts on endoporus gas and blocks up between piston, piston and cylinder barrel junction are provided with O type cushion rubber, endoporus gas blocks and is stained with rubber cushion, the outer hole of ring-type gas blocks and is stained with rubber cushion, 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, inner spring base 3, 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, rubber cushion 9, rubber cushion 10.
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, inner spring base 3, piston 4, O type cushion rubber 5, cylinder barrel 6, endoporus gas stifled 7, the outer hole of ring-type gas stifled 8, rubber cushion 9, rubber cushion 10, it is characterized in that, described outer spring 1, inner spring 2 is all arranged in piston 4 and cylinder barrel 6, outer spring 1 acts between cylinder barrel 6 and piston 4, inner spring 2 acts between endoporus gas stifled 7 and piston 4, piston 4 and cylinder barrel 6 junctions are provided with O type cushion rubber 5, on endoporus gas stifled 7, be stained with rubber cushion 9, on the outer hole of ring-type gas stifled 8, be stained with rubber cushion 10, 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.
