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

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] 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.

[0021] Such as figure 1 As shown, a variable-diameter Huff joint includes two semi-annular shells 10, and the two half-annular shells 10 are engaged to form a tubular shell, and the...

Abstract

The invention belongs to the technical field of pipeline installation, and particularly relates to a variable-diameter half joint. The variable-diameter half joint comprises two half-ring-shaped shells, wherein the two half-ring-shaped shells are combined to form a tubular shell, the diameter of one end of the tubular shell is larger than that of the other end of the tubular shell so that the tubular shell can be clamped at the position where two pipelines with different diameters are connected, and sealing gaskets are arranged at the joint of the two half-ring-shaped shells and between pipe orifices at the two ends of the tubular shell and the outer wall of each pipeline. The diameters of the two ends of the half joint change along with the change of the diameters of the pipelines and are designed independently to form the variable-diameter half joint, and the variable-diameter half joint can be used for blocking variable-diameter pipelines to meet actual working condition requirements.

Description

technical field [0001] The invention belongs to the technical field of pipeline installation, and in particular relates to a variable-diameter half joint. 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 object of the present invention is to provide a variable-diameter hal...
