Abstract
The utility model relates to a leak checking and sealing device of a pipeline, which belongs to the field of special leak checking tools. The leak checking and sealing device of the pipeline comprises a spring base, springs, a cylindrical outer hole air block, a rubber pad fixation nut, a cylindrical outer hole air block rubber pad, an inner hole air block rubber pad, a fixation bolt, an inner hole air block and an air inlet hole. The springs are arranged in the cylindrical outer hole air block. The springs act on a space between the spring base and the inner hole air block. The spring base is fixed at the bottom of the cylindrical outer hole air block. The inner hole air block rubber pad is fixed on the inner hole air block through the fixation bolt. The cylindrical outer hole air block rubber pad is fixed on the cylindrical outer hole air block through a rubber pad pressed nut. The air inlet hole is arranged on the side of the cylindrical outer hole air block. According to the leak checking and sealing device, the structure uses the method that double springs apply pressure on the air blocks at the same time; a port of the pipeline can be quickly sealed; the sealing is enhanced; and the detection efficiency is improved.
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: a kind of pipeline leak detection packoff, comprise: spring pedestal, spring, the outer hole of tubular gas is stifled, elastic mounting nut, the stifled rubber cushion of the outer hole of tubular gas, endoporus gas blocks up rubber cushion, set bolt, endoporus gas is stifled, air admission hole, described spring be arranged on the outer hole of tubular gas stifled in, spring action is between spring pedestal and endoporus gas are stifled, spring pedestal is fixed on the stifled bottom of gas, the outer hole of tubular, the stifled rubber cushion of endoporus gas is fixed on endoporus gas by set bolt and blocks, gas stifled rubber cushion in the outer hole of tubular is fixed on the outer hole of tubular gas by rubber cushion gland nut and blocks, air admission hole is arranged on Qi Du side, the outer hole of tubular.
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: a kind of pipeline leak detection packoff, comprising: the outer hole of spring pedestal 1, spring 2, tubular gas is stifled 3, elastic mounting nut 4, the stifled rubber cushion 5 of the outer hole of tubular gas, the stifled rubber cushion 6 of endoporus gas, set bolt 7, endoporus gas are stifled 8, air admission hole 9.
Embodiment:
Below in conjunction with drawings and Examples, the utility model is described in further detail:
2.referring to accompanying drawing
1.a kind of pipeline leak detection packoff, comprise: spring pedestal 1, spring 2, the outer hole of tubular gas stifled 3, elastic mounting nut 4, the stifled rubber cushion 5 of the outer hole of tubular gas, endoporus gas blocks up rubber cushion 6, set bolt 7, endoporus gas stifled 8, air admission hole 9, described spring 2 is arranged in the outer hole of tubular gas stifled 3, spring 2 acts between spring pedestal 1 and endoporus gas stifled 8, spring pedestal 1 is fixed on stifled 3 bottoms of gas, the outer hole of tubular, the stifled rubber cushion 6 of endoporus gas is fixed on endoporus gas stifled 8 by set bolt 7, gas stifled rubber cushion 5 in the outer hole of tubular is fixed on the outer hole of tubular gas stifled 3 by rubber cushion gland nut 4, air admission hole 9 is arranged on stifled 3 sides of gas, the outer hole of tubular.
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 tubular 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 tubular between stifled enters and be detected in pipeline.
