Description
Technical Field
The invention relates to the technical field of seal detection, in particular to a pipeline inlet and outlet hole wall tightness inspection tool.
Background
In the prior art, the wall thickness of a cast or machined pipeline in some cases is thinner, and the tightness of the pipeline can be effectively checked by adopting an oil pressure or air pressure mode at present, but the tightness of a hole at an inlet and an outlet of the pipeline is not checked by an effective tool.
Disclosure of Invention
The invention solves the technical problems that: the hole tightness checking tool is simple in structure and convenient to operate.
The technical scheme of the invention is as follows: a pipeline inlet and outlet hole wall tightness checking tool comprises a hole, a sealing tool body and a sealing tool body, wherein the hole is an inlet and outlet of a 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 externally connected with an air source interface, and a passage for communicating the air source interface with the closed cavity is formed in the tool; the walls of the wells were placed in the liquid during the examination. The tool and the use environment thereof provide a simple structure, and solve the technical problem that the tightness of the hole wall 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 for processing and realizing.
Preferably, the tool comprises a plurality of holes which are penetrated radially, and the angles of the holes are different. The technical scheme ensures the ventilation uniformity of the closed cavity at all angles.
Drawings
FIG. 1 is a schematic view of the structure of the present invention in use;
FIG. 2 is a cross-sectional view A-A;
FIG. 3 is a sectional view B-B.
Detailed Description
As shown in fig. 1-3, the tool in the technical scheme comprises a pipe joint 1 and rubber rings, wherein an axial blind hole and two groups of crisscross radial through holes are formed in the pipe joint, an included angle between the two groups of crisscross through holes is 45 degrees, and two rubber ring grooves are formed in the pipe joint.
When the device is used, firstly, the rubber ring is installed in the rubber ring groove, and the pipe joint 1 is installed in the threaded hole of the pipe line of the casing 2; the whole casing 2 is immersed in water, and finally high-pressure gas is introduced into the inlet of the pipe joint 1. Because two groups of crisscross through holes which form an angle of 45 DEG are formed in the pipe joint, high-pressure gas can be guaranteed to fully enter the threaded fit clearance, meanwhile, under the action of the upper rubber ring and the lower rubber ring, the gas can be effectively stored in the threaded fit clearance, and if the threaded hole is communicated with the outer wall, a large amount of bubbles can be generated in water, so that the purpose of checking the tightness of the threaded hole is achieved.
