Problems solved by technology

[0004] The sealing performance of the connecting pipe is poor. When the connection is bent or twisted by external force, there will be a gap between the pipe and the connecting pipe, resulting in liquid leakage; in addition, when connecting the pipes, it is necessary to wrap waterproof tape at the mouth of the pipes Or apply waterproof glue, the installation process is more complicated

Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] Such as figure 1 and figure 2 The leak-proof pipe connection shown includes a large pipe fixing part 1 and a small pipe fixing part 2. The large pipe fixing part 1 and the small pipe fixing part 2 are integrated and communicated internally. The large pipe fixing part 1 is used for pipes with larger diameters. Fixing, the small pipe fixing part 2 is used for fixing pipes with smaller diameters, which can connect two pipes with different diameters through the leak-proof pipe connecting pipe.

[0028] The inner wall of the large tube fixing part 1 is provided with three anti-leakage rings 10, and the three anti-leakage rings 10 are arranged in turn at the nozzle of the large tube fixing part 1; the inner wall of the small tube fixing part 2 is also provided with three anti-leakage rings 10, three 10 leak-proof rings are sequentially arranged at the nozzle of the...

Abstract

The invention discloses a leak-proof pipe connecting pipe. The gap between the pipe and the inner wall of the connecting pipe is completely sealed by a leak-proof ring arranged inside the connecting pipe to achieve the purpose of leak-proofing. The main points of the technical solution are: a leak-proof pipeline connection pipe, including a large pipe fixing part and a small pipe fixing part, characterized in that the large pipe fixing part and the small pipe fixing part are integrated and connected internally, and the inner wall of the large pipe fixing part is provided with at least A leak-proof ring, the leak-proof ring is located at the nozzle of the large tube fixing part, the leak-proof ring is an annular sheet, and the outer wall of the leak-proof ring is fixed on the inner wall of the big tube fixing part without leaving any gaps. The leakage-proof pipe connecting pipe of the present invention can completely seal the gap between the pipe and the inner wall of the fixed part of the large pipe, and the liquid or gas flowing out of the joint of the pipe cannot be discharged outside, so as to achieve the purpose of leak prevention.

Description

technical field [0001] The invention relates to the field of pipeline equipment, in particular to a leak-proof pipeline connection pipe. Background technique [0002] Pipelines are often used for the transportation of liquids and gases. They are an indispensable device for people’s daily life, factory production operations, and water source energy transportation. They are mainly used in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, and agricultural In irrigation, hydraulic engineering and various industrial installations. Pipelines are generally produced in sections, and the length of each section is limited, and the sizes of pipe fittings produced are also different according to different uses and transportation volumes. The pipes are connected together by connecting devices; or when it is necessary to branch the transported liquid / gas, it is also necessary to connect the thinner branch pipes to the thicker main pipes...
