Abstract
The utility model relates to a sealed detection technical field, in particular to pore wall leakproofness inspection frock is imported and exported to pipeline. The tool is positioned in the hole, the tool is sealed with the hole at the opening end of the hole, and a closed cavity is formed between the inner wall of the hole and the tool; the tool is connected with an air source interface outside the hole, and the tool is provided with a passage for communicating the air source interface with the closed cavity; for inspection, the walls of the wells are placed in a liquid. This frock and service environment thereof provides a simple structure, has solved the technical problem that the pore wall leakproofness is difficult to detect.
Description
Technical Field
The invention relates to the technical field of sealing detection, in particular to a tool for checking the sealing property of the wall of an inlet/outlet hole of a pipeline.
Background
In the prior art, the wall thickness of a cast or machined pipeline in some casings is thin, the tightness of the pipeline can be effectively checked by adopting an oil pressure or air pressure mode at present, but the tightness of holes at an inlet and an outlet of the pipeline is not checked by an effective tool.
Disclosure of Invention
The technical problems solved by the invention are as follows: the hole sealing performance inspection tool is simple in structure and convenient to operate.
The technical scheme of the invention is as follows: a kind of pipeline imports and exports the hole wall leak tightness and checks the frock, the said hole is the import and export of the pipeline; the tool is positioned in the hole, the tool is sealed with the hole at two ends of the hole, and a closed cavity is formed between the inner wall of the hole and the tool; the tool is connected with an air source interface outside the hole, and the tool is provided with a passage for communicating the air source interface with the closed cavity; for inspection, the walls of the wells are placed in a liquid. This frock and service environment thereof provides a simple structure, has solved the technical problem that the pore wall leakproofness is difficult to detect.
Preferably, the liquid is water. The technical scheme is simple and easy to realize.
Preferably, the tool is provided with a cavity along the axial direction and a through hole along the radial direction. The technical scheme is convenient to process and realize.
Preferably, the tool comprises a plurality of holes which are radially communicated, and the angles of the holes are different. The technical scheme ensures the ventilation uniformity of the enclosed cavity at all angles.
Drawings
FIG. 1 is a schematic structural view of a use state of the present invention;
FIG. 2 is a sectional view taken along line A-A;
fig. 3 is a sectional view B-B.
Detailed Description
As shown in fig. 1-3, the tooling of the technical scheme includes a pipe joint 1 and a rubber ring, wherein an axial blind hole and two groups of criss-cross radial through holes are formed in the pipe joint, an included angle between the two groups of criss-cross through holes is 45 °, and two rubber ring grooves are formed in the pipe joint.
When the rubber ring is used, the rubber ring is arranged in a rubber ring groove, and the pipe joint 1 is arranged in a threaded hole of a pipeline of the casing 2; then the whole body of the casing 2 is immersed in water, and finally high-pressure gas is introduced at the inlet of the pipe joint 1. Because of there being two sets of criss-cross 45 jiaos of through-holes that become on the pipe joint, can guarantee that high-pressure gas fully gets into the screw-thread fit clearance, simultaneously under the effect of two upper and lower rubber rings, gaseous can effectively be preserved in the screw-thread fit clearance, if the screw hole link up with the outer wall, the aquatic can produce a large amount of bubbles to reach the purpose of inspection screw hole leakproofness.
