Leakage-proof pipeline connecting device

Abstract

The invention provides a leakage-proof pipeline connecting device. The leakage-proof pipeline connecting device comprises a male connector and a female connector, wherein the male connector and the female connector are respectively and externally connected with pipelines; the male connector is provided with a boss, the female connector is provided with a concave cavity, and the shape of the boss is matched with that of the concave cavity; a boss thread is formed in the outer surface of the boss, a concave cavity thread is formed in the concave cavity, the boss thread and the concave cavity thread can be connected in a matching and rotating manner, and the boss thread and the concave cavity thread both adopt double-thread structures. The leakage-proof pipeline connecting device disclosed by the invention has the advantages and the benefits of simple structure and good leakage-proof effect, and the mounting is quick.

Description

technical field [0001] The invention belongs to the technical field of liquid conveying devices, and in particular relates to an anti-leakage pipeline connection device. Background technique [0002] In the prior art, most of the domestic tap water pipes are arranged with flexible pipes, and the flexible pipes gradually replace the current galvanized pipes. The use of hoses mainly reflects the characteristics of the material. It can be bent and straightened at will. The joints between the pipes are glued together, which makes the installation faster and requires less auxiliary equipment. Unlike galvanized pipes, it is necessary to pull the teeth Equipment, cutting saw blades, etc. Although the connection between hoses is fast, there are relatively large defects. Sometimes due to uneven glue coating, some parts are not tightly sealed, resulting in side leakage. Sometimes after the water leakage test is done, it seems that there is an illusion of no water leakage on the surf...

AI Technical Summary

Problems solved by technology

Although the connection between the hose and the hose is fast, there are large defects. Sometimes due to uneven glue coating, some parts are not tightly sealed, resulting in side leakage.

Sometimes after the water leakage test is done, it seems that there is no water leakage on the surface. After various processes such as moving, piercing pipes, and landfilling, it is difficult to detect subtle water leakage, which can easily cause damage to the decoration.
