Abstract

The utility model relates to a special putting branch pipe for pipes, which is composed of a branch pipe body, a sealing end cover combined with the branch pipe body through bolts and a sealing ring. The utility model makes the branch pipe putting work easy, labor-saving and time-saving and ensures construction quality. The pipe can be put into operation immediately after the construction, so the special putting branch pipe completely cancels the time of a conventional pipe interface for cement curing, and thus shortens inconvenience on urban dwellers' life brought by stopped water supply because of putting pipes, or adverse effect brought on the production of industrial and mining establishments.

Description

Flanged joint

The utility model relates to original pipeline, particularly the tap water main pipe is implemented opening and is put breeches pipe in a kind of pipeline special use that opening is set up breeches pipe (or be called draw threeway).

In the prior art to original pipeline, the method of construction (as shown in Figure 1) that the tap water main pipe is implemented opening and set up breeches pipe at opening particularly, all adopt a end to insert in the bellmouth of threeway with open section, with casing joint the other end and the threeway of open section are joined again, with concrete it is encapsulated then, it is open-minded to treat can discharge water after the concrete setting.This traditional method of construction is not only original but also heavy, and not only labor intensity is big, inefficiency, also owing to must stop 24 hours after the construction, treats after the concrete setting, can open a sluice gate and draw out some water, and has directly influenced life, the process water of resident and enterprise.

The purpose of this utility model just is to overcome above-mentioned deficiency of the prior art, and short, good seal performance of a kind of easy for installation, construction time is provided, and breeches pipe is put in the pipeline special use that can obviously increase work efficiency.

The purpose of this utility model can adopt following measure to realize:

It is by breeches pipe body and the end cover that lumps together by bolt and breeches pipe bulk junction that breeches pipe is put in pipeline special use of the present utility model, and seal ring is formed.

All be processed with an annular groove that matches with seal ring at breeches pipe body two ends, to guarantee the sealing reliability of pipeline junction.

Use product of the present utility model can make pipeline put fork work and become simple, laborsaving, save time and can guarantee construction quality, construction finishes pipeline is put into operation, fully phased out the time of traditional pipe joint need cement conservation, shortened greatly because of pipeline and put the fork inconvenience that life to the town dweller brings that stops to supply water, or the adverse effect that the production of industrial and mining enterprise is brought.

The drawing of accompanying drawing is described as follows:

Fig. 1: prior art structural drawing.

Fig. 2: plan view of the present utility model.

The utility model is done with detailed description below with reference to embodiment's (accompanying drawing):

As shown in the figure, it is by breeches pipe body (3) and the end cover (2) that lumps together by bolt and breeches pipe bulk junction that breeches pipe is put in pipeline special use of the present utility model, and seal ring (1) is formed.

All be processed with an annular groove that matches with seal ring at breeches pipe body (3) two ends, to guarantee the sealing reliability of pipeline junction.

Use product of the present utility model to carry out pipeline when putting fork work, only need breeches pipe is placed in opening, with connected nut end cover and breeches pipe bulk junction are lumped together to open a sluice gate and draw out some water and make the pipeline normal operation input.

Claims

1, the utility model is that breeches pipe is put in a kind of pipeline special use, it is characterized in that: it is by breeches pipe body (3) and the end cover (2) that lumps together by bolt and breeches pipe bulk junction, and seal ring (1) is formed.

2, breeches pipe is put in pipeline special use according to claim 1, it is characterized in that: breeches pipe body (3) two ends all are processed with an annular groove that matches with seal ring.
