Problems solved by technology

However, the Huff joints in the prior art are often of equal-diameter structure, and it is difficult to say that the pipeline is completely sealed when faced with some complicated working conditions.
For example, at the joint of two pipes with different diameters, the traditional equal-diameter half joint cannot be closely matched with the two pipes at the same time, so a new type of half joint structure is urgently needed to meet the requirements of this working condition

Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0016] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings (that is, the side that cooperates with the pipeline is the inner side, and the side that is away from One side of the pipe is the outer side) is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, configuration and operation, and therefore should not be construed as a limitation of the present invention.

[0017] Such as figure 1 As shown, a variable-diameter half-shaped housing includes two half-annular housings 10, and the two half-annular housings 10 are engaged to form a tubular h...

Abstract

The invention belongs to the technical field of pipe installation, and particularly relates to a variable-diameter type Huff section shell. The variable-diameter type Huff section shell comprises two semi-ring casings, wherein the two semi-ring casings are clamped to constitute a pipe-like casing, and the diameter of one end of the pipe-like casing is larger than that of the other end, so that the pipe-like casing can be clamped at the joint of two pipes with different diameters. The diameters of two ends of a Huff section are independently designed according to change of the diameters of the pipes, and the variable-diameter type Huff section shell is formed and can be used for blocking variable-diameter pipes so as to meet requirements of actual working conditions.

Description

technical field [0001] The invention belongs to the technical field of pipeline installation, and in particular relates to a variable-diameter half joint shell. Background technique [0002] The Huff joint is mainly used in the fields of pipeline repair or pipeline connection. Its structure mainly includes two half shells, and the two half shells can be buckled together to form a sleeve, which is clamped on the pipeline. However, the half joints in the prior art are often of equal-diameter structure, and it is difficult to say that the pipeline is completely sealed when faced with some complicated working conditions. For example, at the joint of two pipes with different diameters, the traditional equal-diameter half joint cannot closely fit the two pipes at the same time, so a new half joint structure is urgently needed to meet the requirements of this working condition. Contents of the invention [0003] The purpose of the present invention is to provide a diameter-reduc...
