Pipeline branching device

Abstract

The invention discloses a pipeline branching device which comprises a first saddle part and a second saddle part that have same structure, are individuals and are fixedly connected, as well as a lower connecting piece; each of the first saddle part and the second saddle part respectively comprises a substrate with a cambered side surface, and a semi-cylindrical branch part which is positioned at the edge of the substrate and extends towards the protrusion direction of the substrate, and a semicircular installation part which is positioned at the end of the branch part; the substrate of the first saddle part and the substrate of the second saddle part define a saddle structure; the branch part of the first saddle part and the branch part of the second saddle part define a cylinder structure; the installation part of the first saddle part and the installation part of the second saddle part define a circle structure; the end of the lower connecting piece is fixedly connected with the first saddle part and / or the second saddle part, and a main pipeline is positioned in the circular structure defined by the lower connecting piece and the substrate. The pipeline branching device facilitates adoption of two-box modeling process, and is simple to operate and high in casting efficiency.

Description

Technical field [0001] The invention relates to the technical field of pipeline branches, and more specifically, to a pipeline branch device. Background technique [0002] At present, in the urban water supply, gas and petrochemical industries, pipelines are used to transport media. In order to meet the needs of people's production and life, it is often urgent to add branch pipelines. [0003] See figure 1 , The Chinese patent application number 200520009786.X discloses a pipe branch pipe clamp, including a saddle-shaped upper pipe clamp 1, one or more lower pipe clamps 3, and a fixed connection between the upper pipe clamp 1 and the lower pipe clamp 3 Connecting bolt 2, wherein the arcuate top surface of the upper pipe clamp 1 is provided with a through hole 5 perpendicular to the axis of the pipe clamp; the bottom of the through hole 5 is equipped with an annular sealing ring 4, and the through hole 5 is located on the upper pipe clamp 1. The middle part of the top surface exten...

AI Technical Summary

Problems solved by technology

[0004] In the pipeline branch pipe clamp disclosed in the above Chinese patent, the upper pipe clamp 1 is manufactured by sand casting process, and its through hole 5 is annular, and the end of the through hole is provided with a mounting platform larger than its main body. This structure applies two The box molding cannot be molded, so it can only be manufactured by the three-box molding method, and the operation of the three-box molding process is complicated, and the casting process takes a lot of time, and the casting efficiency is low

[0005] In addition, each of the three boxes needs a model, so three models need to be made when manufacturing the upper branch pipe. The workload and difficulty of making the models are large, and the total cost of the models is relatively high. At the same time, the time to manufacture the models is relatively short. long, low productivity
