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, an inner hole air block, an inner hole air block rubber pad and a cylindrical outer hole air block rubber pad. 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 adhered on the inner hole air block. The cylindrical outer hole air block rubber pad is adhered on 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: 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 block up, endoporus gas is stifled, endoporus gas blocks up rubber cushion, the stifled rubber cushion of the outer hole of tubular gas, 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, endoporus gas blocks and is stained with the stifled rubber cushion of endoporus gas, and the outer hole of tubular gas blocks and is stained with the stifled rubber cushion of the outer hole of tubular 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: a kind of pipeline leak detection packoff, comprising: the outer hole of spring pedestal 1, spring 2, tubular gas is stifled 3, endoporus gas is stifled 4, the stifled rubber cushion 5 of endoporus gas, the stifled rubber cushion 6 of the outer hole of tubular 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: the outer hole of spring pedestal 1, spring 2, tubular gas is stifled 3, endoporus gas is stifled 4, the stifled rubber cushion 5 of endoporus gas, the stifled rubber cushion 6 of the outer hole of tubular gas, 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 4, spring pedestal 1 is fixed on stifled 3 bottoms of gas, the outer hole of tubular, on endoporus gas stifled 4, be stained with the stifled rubber cushion 5 of endoporus gas, on the outer hole of tubular gas stifled 3, be stained with the stifled rubber cushion 6 of the outer hole of tubular gas.
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.
Claims (1)
1. a pipeline leak detection packoff, comprise: spring pedestal, spring, the outer hole of tubular gas block up, endoporus gas is stifled, endoporus gas blocks up rubber cushion, the stifled rubber cushion of the outer hole of tubular gas, it is characterized in that, 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, and endoporus gas blocks and is stained with the stifled rubber cushion of endoporus gas, and the outer hole of tubular gas blocks and is stained with the stifled rubber cushion of the outer hole of tubular gas.
