Abstract

The utility model relates to a plastic reducing three-way pipe fitting, which is composed of a main pipe, branching pipes and reinforcing segments, the whole body is a hollow structure, wherein, the reinforcing segments are in a structure that reinforcing ribs are arranged in annular grooves. The utility model solves the problem that air bubbles and shrinkage holes are easy to generate since an existing structure is partially too thick, and thereby, production efficiency is enhanced by disposable injection molding. The utility model provides a plastic reducing three-way pipe fitting which has the advantages that the structure of the plastic reducing three-way pipe fitting is more reasonable and safer so that integral strength is enhanced and production difficulty is reduced. The utility model is widely used in a water supplying system and a combustion gas pipe network system.

Description

Plastics reducing tee pipe fitting

Technical field:

The utility model belongs to a kind of plastics reducing tee pipe fitting, the plastics reducing tee pipe fitting in particularly a kind of feedwater and the fuel gas transportation pipeline system.

Background technique:

Existing plastic three-way pipe fitting is a technique known, announced a kind of plastic three-way pipe fitting in the utility model patent 99229330.9 of Zhong Jianzhong design, the tee pipe fitting of forming by three-way straight pipe, tee branch, wherein the port of tee branch has flange plate, and the interface of tee branch part can only match with flange, interface is single.

Announced a kind of heavy caliber reducing tee in the utility model patent 01215232.9 of people such as Wang Youyin design, form by main pipe and branched pipe, wherein main pipe adopts the cambered surface axis way parallel with main axis with the branched pipe crossover sites, caused like this and strengthened that section is blocked up to make the inside of strengthening section in the injection moulding process easily produce bubble, cooling procedure easily to produce shrinkage cavity, the intensity that inner bubble and shrinkage cavity have reduced pipe fitting, but externally be that this that do not observe stayed unsafe hidden danger to engineering.The branched pipe extension adopts the way with the main pipe welding, needs the secondary operations pipe fitting to make manufacturing efficiency reduce.

Summary of the invention:

The utility model is to overcome above-mentioned deficiency of the prior art, develops a kind of interface for multiple connection, and the plastics reducing tee of process single injection-molded.The utility model is achieved in that integral body is the structure of a hollow, form by main pipe, branched pipe, reinforcement section, wherein strengthening section is by the structure of being with stiffening rib in the circular groove, solved the existing structure sunburner and easily produced the problem of bubble, shrinkage cavity, once injection moulding has improved manufacturing efficiency.

The utility model provides the plastics reducing tee pipe fitting that a kind of structure is more reasonable, safe and reliable, bulk strength raising, production difficulty are reduced, and is widely used in feedwater, the gas distribution system, gas network.

Description of drawings: Fig. 1: be plan view of the present utility model; Fig. 2: be plan view of the present utility model;

Embodiment:

The utility model is achieved in that integral body is the structure of a hollow, form by main pipe 1, branched pipe 2, reinforcement section 3, the section of reinforcement 3 is arranged on the circumferencial direction of the center portion of main pipe 1, main pipe 1 has an outstanding circular groove 4 with branched pipe 2 infalls, circular groove 4 passes through mutually with the outside of main pipe 1, there are six to eight stiffening ribs 5 inside of circular groove 4, and stiffening rib 5 is along the circumferential direction uniform and be connected with circular groove 4 and arm 2, and branched pipe 2 connects with main pipe 1.
