Abstract

The utility model discloses a concentric different-diameter pipe formed by lengthening one end of a branch pipe and one end of a main pipe of a regular tee joint. The concentric different-diameter pipe comprises the regular tee joint and a first end, arranged on the regular tee joint, of the main pipe, and further comprises a first concentric different-diameter pipe, wherein the first concentric different-diameter pipe is communicated with the first end of the main pipe, and the first concentric different-diameter pipe and the first end of the main pipe are integrally formed. Due to the facts that the one end of the branch pipe and the one end of the main pipe of the regular tee joint are lengthened and the diameter of one end of the branch pipe and the diameter of one end of the main pipe of the regular tee joint are changed to form the concentric different-diameter pipe, flow and the flow speed of media are changed and on-site construction and installation are facilitated; due to the facts that the one end of the branch pipe and the one end of the main pipe of the regular tee joint are lengthened and the diameter of one end of the branch pipe and the diameter of one end of the main pipe of the regular tee joint are changed to form the concentric different-diameter pipe, the concentric different-diameter pipe is formed through a forming die, so potential quality hazards and environment pollution caused by on-site welding are avoided; Teflon non-stick coating processing is adopted in the tee joint, surface smoothness of the tee joint is improved, and the flow speed of the media is increased; due to the fact that Teflon non-stick coating processing is adopted in the tee joint, a lot of manpower, material (polished section) consumption and environment pollution are avoided.

Description

The Concentric Reducers that a kind of positive tee branch road and main line one end lengthen

Technical field

The utility model relates to body technical field, the Concentric Reducers that a kind of positive tee branch road and main line one end lengthen specifically.

Background technique

Positive threeway is 90 degree and intersects, the pipe of three mouths of pipe.Positive threeway can be used for the branch of pipeline and converges, can be for the current of a pipeline be shunted, and also can be for the current of 2 pipelines are compiled in to 1, so positive threeway is the pipe fitting of often using in pipe laying.

Concentric Reducers is that steel is colded pressing or hot-forming reducer, and its Connecting format is exactly directly by one end butt welding of reducer and main line.

Referring to Fig. 1 and Fig. 2, the structural representation that Fig. 1 is prior art; Fig. 2 is A-A sectional view of Fig. 1.Its structure comprises main line 2 and bye-pass 5, and main line 2 comprises first end 21 and the second end 22.

In pressure piping, by positive threeway 1(two axial lines, intersect in same level) rate-of flow while changing, as increased or reducing, when change in flow is little, general employing is welded with Concentric Reducers 6 at the first end face 21 of the bye-pass 5 of positive threeway 1 and the main line 2 of positive threeway 1 or the second end face 22 and installs and change, and by welding bead 7, completes.

Existing production technology, causes on-the-spot system to adopt welding to become, and has following shortcoming;

1, the product that existing production technology is produced cannot meet corresponding requirement.

2, above-mentioned general employing is welded with Concentric Reducers 3 and installs and change on positive tee branch road 5 and on the first end 21 of positive threeway main line 2 or the second end 22.Welding bead 7 quality are by the hidden danger of quality place in build-up of pressure piping element thus.

3, cause the loss of wlding, the waste material producing due to welding causes certain pollution to environment.

4, pipeline internal medium, especially particulate species medium, can produce and pile up at threeway shoulder fault location, finally causes pipeline to stop up, and impact is normally produced.

Therefore, the Concentric Reducers that needs especially a kind of positive tee branch road and main line one end to lengthen, to solve problems of the prior art.

Model utility content

The purpose of this utility model is in order to solve in prior art, the pipeline flow change in flow that changes need adopt the mode of welding to connect Concentric Reducers when little, cost is higher, there is the defect of hidden danger of quality, the Concentric Reducers that provides a kind of positive tee branch road and main line one end to lengthen, to solve problems of the prior art.

For achieving the above object, the technical solution of the utility model is as follows:

The Concentric Reducers that a kind of positive tee branch road and main line one end lengthen, comprise positive threeway and be arranged on the main line first end in positive threeway, also comprise the first Concentric Reducers, described the first Concentric Reducers is communicated with main line first end, and described the first Concentric Reducers and main line first end are one-body molded.

In the utility model, also comprise the second Concentric Reducers and bye-pass, described the second Concentric Reducers connected component pipeline, described the second Concentric Reducers and bye-pass are one-body molded.

In the utility model, the outer diameter of described main line and bye-pass is respectively 21.3mm-530mm.

In the utility model, the inwall of described positive threeway arranges Teflon layer.

Beneficial effect

1, owing to aligning tee branch road, become Concentric Reducers with main line one end lengthening reducing, thereby changed flow and the flow velocity of medium, facilitated site operation installation.

2, owing to aligning tee branch road, becoming Concentric Reducers with main line one end lengthening reducing, is by shaping die, has avoided the hidden danger of quality and the environmental pollution that due to Site Welding, cause.

3, by take teflon non-stick coating to process to threeway, improve threeway internal surface degree of finish, accelerated the flow velocity of medium; By take teflon non-stick coating to process to threeway, a large amount of artificial, material (polished silicon wafer) loss and environmental pollution have been avoided.
