Description

Tee joint structure for pipeline

Technical Field

The utility model belongs to the technical field of three-way pipelines, and particularly relates to a three-way structure for a pipeline.

Background

At present, when the pipeline under pressure is perforated, the tee pipe fitting is usually welded on the low-pressure stainless steel pipeline firstly, then the puncher is used for punching the pipeline with the tee pipe fitting, but the pipe wall thickness of the low-pressure stainless steel pipeline is different, so that the welding installation of the conventional tee pipe fitting is not facilitated, and the adaptability of the conventional tee pipe fitting and the low-pressure stainless steel pipeline is poor.

Disclosure of utility model

In order to solve the technical problems, the utility model provides a tee joint structure for pipelines, which utilizes a non-welded perforated tee joint to perform branch pipe connection operation and is suitable for the perforated branch pipe connection operation of low-pressure stainless steel pipelines.

The utility model is realized by the following technical scheme:

a tee bend structure for pipeline, includes the backplate and sets up with last backplate in pairs lower backplate, the both sides of going up the backplate and the both sides of backplate down all are integrated to be provided with the connecting plate, and the both ends inside of going up the backplate and the both ends inside of backplate down all are seted up flutedly, are provided with the pillar between the connecting plate that upper and lower two just set up, and the upper and lower both ends of pillar all are provided with annular gasket, installs bolt and nut between upper and lower two just set up the connecting plate.

Preferably, the upper opening of the upper guard plate is welded and fixed with a branch pipe.

Preferably, each connecting plate is provided with a mounting hole.

Compared with the prior art, the utility model has the beneficial effects that:

In the utility model, the arrangement of the upper guard plate, the lower guard plate, the branch pipes, the connecting plates and the mounting holes is suitable for the operation of tapping the low-pressure stainless steel pipeline and connecting the branch pipes.

In the utility model, the arrangement of the support, the annular gasket, the bolts and the nuts is beneficial to supporting the upper guard plate and the lower guard plate, and reduces the deformation of the connecting plate of the upper guard plate and the connecting plate of the lower guard plate.

FIG. 1 is a schematic diagram of the structure of the present utility model;

FIG. 2 is a schematic side elevational view of the present utility model;

Fig. 3 is a schematic cross-sectional view of the present utility model.

In the figure:

1. an upper guard board; 2, a lower guard board, 3, a branch pipe, 4, a connecting board, 5, a mounting hole, 6, a groove, 7, a pillar, 8, an annular gasket, 9 and a bolt and a nut.

Detailed Description

The utility model is specifically described below with reference to the accompanying drawings, as shown in fig. 1 and fig. 2, the tee joint structure for pipelines comprises an upper guard plate 1 and a lower guard plate 2 which is arranged in pairs with the upper guard plate 1, branch pipes 3 are welded and fixed at openings of the upper part of the upper guard plate 1, connecting plates 4 are integrally arranged on two sides of the upper guard plate 1 and two sides of the lower guard plate 2, mounting holes 5 are formed in each connecting plate 4, grooves 6 are formed in two ends of the upper guard plate 1 and two ends of the lower guard plate 2, the grooves 6 arranged on two upper parts and the grooves 6 arranged on two lower parts are respectively and oppositely arranged, a strut 7 is arranged between the upper and lower connecting plates 4 and is arranged between the upper and lower connecting plates 5 and is arranged between the upper and lower connecting plates 4, annular gaskets 8 are arranged at the upper and lower ends of the strut 7, the strut 7 and the annular gaskets 8 support the connecting plates 4 of the upper guard plate 1 and the lower guard plate 2, and the deformation of the connecting plates 4 is reduced.

In this embodiment, specifically, a through hole is formed in the pillar 7.

In this embodiment, specifically, a bolt and nut 9 is installed between the upper and lower connection plates 4 which are disposed opposite to each other.

Principle of operation

In the utility model, the upper guard plate 1 and the lower guard plate 2 are arranged on the upper side and the lower side of the outer surface of a cleaned pipeline to be perforated, rubber sealing elements are additionally arranged in the grooves 6, the upper connecting plate 4 and the lower connecting plate 4 are fixed through bolts and nuts 9, a valve is arranged at the upper end of the branch pipe 3, the whole pressure test is qualified, the perforating operation with pressure is carried out, and the relevant pipeline is connected at the valve after the perforation is finished, so that the problem that the branch pipe is connected due to the thin wall of the pipeline and the perforation is required is solved.

By using the technical scheme of the utility model or under the inspired by the technical scheme of the utility model, a similar technical scheme is designed by a person skilled in the art, so that the technical effects are achieved, and the technical effects fall into the protection scope of the utility model.
