Abstract
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
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.
