Reducing two-way pipe joint

Abstract

The invention relates to the field of pipeline joints, in particular to a reducing two-way pipe joint. The reducing two-way pipe joint comprises a telescopic joint assembly, two connecting assemblies,sealing assemblies and a filtering assembly, wherein the connecting assemblies are separately fixedly mounted at the two opposite ends of the telescopic joint assembly; the two connecting assembliesare a large-aperture connector and a small-aperture connector separately; the sealing assemblies are separately fixedly mounted on the sides, which are away from the telescopic joint assembly, of thelarge-aperture connector and the small-aperture connector; and the filtering assembly is mounted on the side, which is close to the large-aperture connector, of the inside of the telescopic joint assembly. By a telescopic joint assembly pipe body and an adjustable supporting mechanism, two pipes with different distances can be connected through the joint, the reducing two-way pipe joint is convenient and rapid to mount and operate, the connecting assemblies and the sealing assemblies are arranged, an O-shaped sealing ring is inserted into a sealing projection, the sealing projection extrudes the O-shaped sealing ring so that the O-shaped sealing ring is abutted to the outer wall of a pipe, the sealing property of the joint is improved, the O-shaped sealing ring is prevented from falling off, and the reliability of sealing and leakage prevention is guaranteed.

Description

technical field [0001] The invention relates to the field of pipe joints, in particular to a variable-diameter two-way pipe joint. Background technique [0002] Pipe joints are parts that connect pipelines or install pipelines on hydraulic components in hydraulic systems. This is a general term for connectors that can be assembled and disassembled in fluid passages, mainly including: welding type, ferrule type, buckle type And flaring type, including end straight joints, straight joints, tee joints, elbows, joints with live nuts, hinged joints, plugs, transition joints, etc., the materials are commonly used in stainless steel and carbon steel metric, American and British thread standards . [0003] Between two pipes with different calibers, two-way pipe joints are used to realize variable-diameter installation between the two pipes. At present, the overall length of the two-way pipe joints is fixed. The overall length of the joint is suitable, which makes the installation ...

Problems solved by technology

[0003] Between two pipes with different calibers, two-way pipe joints are used to realize variable-diameter installation between the two pipes. At present, the overall length of the two-way pipe joints is fixed. The overall length of the joint is suitable, which makes the installation between the pipes and the installation between the pipe and the joint complicated, the installation operation is difficult, the installation is time-consuming and laborious, and the threaded installation between the pipe and the joint, the impact of the fluid flowing in the pipe and the joint It acts on the pipe body and joint connection for a long time, resulting in water leakage due to thread installation loss, and poor practicability
