Description

A three-way bottle type silencer spiral pipe fitting

technical field

The utility model relates to a three-way bottle type (different diameter) sound-absorbing spiral pipe fitting, which belongs to the field of plastic water supply and drainage pipe fittings.

Background technique

At present, the plastic tee pipe fittings on the market can only produce tee pipes with the same diameter between the nozzles due to the production process and mold investment costs. When in use, the water supply and drainage pipes with different diameters cannot be connected The connection is very inconvenient to use, and it is necessary to develop a tee fitting with a different diameter (different pipe diameter).

Contents of the invention

The purpose of this utility model is to overcome the shortcomings of the prior art, and provide a three-way bottle-type sound-absorbing spiral pipe fitting that adopts integral processing and has different diameters of the upper and lower pipes, which is convenient for connecting pipes with different diameters.

The technical scheme of a three-way bottle-type silencer spiral pipe fitting of the utility model is: a three-way pipe body composed of a main pipe body and a side pipe body, the upper mouth of the main pipe body is formed with an upper joint, and the lower mouth of the main pipe body is formed with a lower joint , the head of the side pipe body is formed with a three-way joint, which is characterized in that the upper joint or the lower joint is a different-diameter joint.

A three-way bottle-type silencer spiral pipe fitting of the utility model is mainly characterized in that the upper joint or the lower joint of the main pipe body is made into a different-diameter joint, that is, joints of different pipe diameters can be connected to pipe fittings of different pipe diameters, and it is convenient to use , which is conducive to the connection of water supply and drainage pipes. The different-diameter joint and the main body are integrally injection molded at one time. The diameter of the different-diameter joint is small, like the mouth of a bottle, and the shape of the entire pipe is like a bottle. It has good strength and low mold cost investment.

The utility model relates to a three-way bottle-type sound-absorbing spiral pipe fitting. The upper or lower mouth of the main pipe body is made with a trumpet-shaped pipe body, and the different-diameter joint is connected to the main pipe body through the trumpet-shaped pipe body, that is, from the pipe body of the main pipe body. The diameter is gradually reduced to the diameter of the reducing joint, and the strength of the pipe body is good. The outer wall of the different-diameter joint is formed with thread flares, grooves and retaining rings. A buckle can be installed on the thread flares to fasten the pipes to be connected, and a sealing ring can be installed in the grooves. The sealing performance is good, and the different-diameter joints The inner wall of the pipe is made with a caulking groove, and the pipe fittings are inserted into the caulking groove, which is convenient for connection. The arc-shaped spiral pipe transitions between the side pipe body and the main pipe body, and the arc-shaped spiral transition can reduce the noise of water flow and achieve the purpose of noise reduction.

Fig. 1 is a structural schematic diagram of a three-way bottle-type sound-absorbing spiral pipe fitting of the present invention.

Detailed ways

The utility model relates to a three-way bottle-type sound-absorbing spiral pipe fitting, as shown in Figure 1, comprising a three-way pipe body composed of a main pipe body 1 and a side pipe body 2, the upper mouth of the main pipe body 1 is provided with an upper joint 3, and the main pipe body The lower mouth of 1 is shaped on lower joint 4, and the head of side pipe body 2 is shaped on tee joint 5, and described upper joint 3 or lower joint 4 are reducing joints 6. The main feature of this scheme is that the upper joint 3 or the lower joint 4 of the main body 1 is made into a different-diameter joint 6, that is, joints of different pipe diameters, which can be connected to pipe fittings of different pipe diameters. It is easy to use and facilitates the connection of water supply and drainage pipes. . The different-diameter joint and the main body are integrally injection molded at one time. The diameter of the different-diameter joint is small, like the mouth of a bottle, and the shape of the whole pipe is like a bottle, with good strength and low mold cost investment. The upper or lower opening of the main body 1 is formed with a trumpet-shaped pipe body 5, and the different-diameter joint 6 is connected to the main body 1 through the trumpet-shaped pipe body 5, that is, the pipe diameter of the main body is gradually reduced to that of the different-diameter joint. The pipe diameter and the strength of the pipe body are good. The outer wall of the different-diameter joint 6 is formed with a thread flare 7, a groove 8 and a retaining ring 9, a buckle ring can be installed on the thread flare, and the pipe fittings to be connected can be fastened, and a sealing ring can be installed in the groove, and the sealing performance is good , The inner wall of the different-diameter joint 6 is shaped on a caulking groove 10, and the pipe fitting is inserted into the caulking groove, which is convenient for connection. The arc-shaped spiral pipe body 11 transitions between the side pipe body 2 and the main pipe body 1, and the arc-shaped spiral transition can reduce water flow noise and achieve the purpose of noise reduction.
