Embodiment approach

[0022] As an embodiment of the present invention, the reducing unit 3 includes a swivel 31, a reducing plate 32 and a telescopic rod 33; the surface of the pipe body 1 is provided with a circular chute; the swivel 31 slides In the chute, and the sidewalls on both sides of the chute are provided with limit chute, both sides of the swivel 31 are provided with limit blocks, and the limit blocks slide in the limit chute to ensure that the swivel 31 can rotate At the same time, the strength of the pipe body 1 is improved; the diameter-reducing plate 32 is fixedly connected with the expansion rod 33 uniformly arranged in the swivel 31; The arc-shaped design of the plate 32 ensures that the sides of the variable-diameter plates 32 away from the swivel 31 form a circle after contacting each other, and the center of the circle is at the same position as the center of the swivel 31; the variable-diameter plates 32 are slidably connected to each other, And the side walls on both sides of...

Abstract

The invention belongs to the technical field of two-way pipe joints, in particular to a reducing two-way pipe joint. The reducing two-way pipe joint comprises a pipe body; the left end of the pipe body is provided with a sizing interface; sealing units are arranged at the position of the sizing interface; the right end of the pipe body is provided with a reducing interface; a reducing unit is arranged at the position of the reducing interface; the interior of the pipe body is fixedly connected with a rubber ring; the reducing unit comprises a rotating ring, reducing plates and telescopic links; the side face of one side, far away from the rotating ring, of each reducing plate is fixedly connected with a rubber block; a rubber membrane is arranged in the rubber ring; each sealing unit comprises a swing rod, an air bag and sealing rings; and a mandrel is arranged in each of annular cavities. Connection between pipelines different in diameter and the joint is realized by rotating the rotating ring; water leakage at the position of the reducing interface is avoided by double sealing of the rubber blocks and the rubber membrane; the sizing interface is completely sealed under the cooperation of the sealing rings and third cavities; and the reducing two-way pipe joint is high in sealing performance and convenient to disassemble and assemble, and can be firmly connected with the pipelines.

Description

technical field [0001] The invention belongs to the technical field of two-way pipe joints, in particular to a variable-diameter two-way pipe joint. Background technique [0002] The two-way pipe joint is a part that connects the pipeline. This is a general term for a connection that can be assembled and disassembled in the fluid passage. It is an indispensable part for long-distance pipeline transportation. It is mainly used for the connection of pipelines on liquid, gas and hydraulic components. Connect to extend the transportation distance. [0003] Most of the two-way pipe joints in the prior art cannot realize the function of diameter reduction. In order to realize the function of diameter reduction, most of the prior art uses methods such as rings, hot melt, and bonding to fix the pipes and pipe joints together. These locking methods Due to the smooth surface of the joint between the pipe joint and the pipe, the fixation is not firm, and it is easy to cause the pipe t...
