The present invention relates to a T-branch structure for a water supply pipe, and more particularly, to a water supply pipe for allowing tap water to be easily supplied to a branch pipe when tap water supplied from the main water pipe is branched, T-branch structure.

In the related art, there have been proposed various configurations for connecting branch pipes which flow the water flowing in the main pipe of the metal material in the direction of the branch pipe in the connecting operation of the pipe used at the water pipe installation site or the construction site.

As a prior art, there has been filed a utility model registration application No. 2010-08721 (Feb. 29, 2012), a branch organization constituting a connecting jaw has been filed, a utility model registration No. 20-0261551, Also, the utility model registration application No. 1001997-54100 (published on May 15, 1999) was announced.

In the first prior art,

A lower joint is formed at the end of the lower end connecting portion of the branch pipe and a lower end connecting portion and a branch pipe jaw supporting the flange are formed so as to be engaged with the main connecting hole to be supported So that they are connected by welding.

In the second prior art,

A structure in which a branch pipe is joined such that a fluid is partially branched through a branch hole drilled on the outer circumferential surface of a cylindrical water supply and sewage pipe, characterized in that the pipe has two openings And a branch connection pipe having a joint flange attached to the upper end thereof is integrally formed at the upper center of the outer circumferential surface of the joining main body, the inner circumferential surface of which is composed of a rubber band, the inner circumferential surface of which is formed by bending, A rubber ring and a connecting protrusion protruding from a central portion of the circumferential surface are successively inserted into the gap between the branch hole and the branch connection pipe, and a fastening bolt is fastened to the fastening hole formed in the opening, And is inserted and joined together,

In the third prior art,

Generally, as a supply path for connection to automobiles, various mechanical devices, and other lubrication and supply, a pipe fitting of a T-shaped or cross-shaped pipe made of a metal pipe having a relatively small diameter of about 20 m / m or less It is about the recipe.

Wherein the main pipe has a main pipe integrally formed with a separating hole integrally formed in the circumferential wall portion or a separately formed main body having separate parts arranged to be spaced apart from each other at opposite ends thereof and a single pipe having a diameter larger than that of the main pipe, A part of the circumferential wall in the left and right longitudinal direction of the fitting body located on the side of the fitting of the branch tube is left with the part to which the branch tube strikes in a state where the branch pipe is in the vicinity of the branch connection hole of the fitting main body, And the diametrically opposed surfaces are integrally welded to each other in a state in which they are diametrically shrunk and joined to the outer circumferential surfaces of the main pipe and the branch pipe, respectively.

The above-mentioned conventional arrangements are troublesome and inconvenient due to troublesome work, troublesome work takes a long time, uneconomical problems and lack of appearance when installed at exposed positions are disadvantageous. Especially, lack of robustness There are many problems such as leakage when using for a long time.

When the tap water is dispensed from the main water pipe to the branch water pipe, the pressure of the tap water flowing into the main water pipe is not transmitted to the branch pipe, so that the tap water is not properly distributed .

In particular, when tap water is supplied to the branch water pipe located at the first portion or the end portion of the main water pipe or the tap water is supplied to both of them, the pressure of the main water pipe does not function properly with the branch water pipe located at the middle portion, There is a problem that it is not supplied properly.

That is, since the first portion of the main water pipe has the strongest pressure to supply the tap water to a certain distance, the pressure is maintained at the first portion of the main water pipe but the tap water is stagnated at the end portion. The tap water is supplied smoothly. However, the branch pipe located at the middle portion has a problem that the pressure of the tap water is injected at the first and the end portions and the pressure is not properly applied to the middle portion.

The fixing ring 200 not only retains the shape of the bushing 300 but also allows the main mounting projections 121, the sub mounting projections 131 and the branch mounting projections 141 to communicate with the main water pipe 10, The main mounting protrusion 121, the sub mounting protrusions 131 and the branch mounting protrusions 141 are maintained in the shape of "○" when they are pressed and fixed to the sub water pipe 20 and the branch water pipe 30, And the watertightness of the pressed portion is maintained evenly.

The main water pipe 10 is inserted into the main connection part 120 and the main installation protrusion 121 is compressed by using a compression device so that the bushing 300 installed inside the main installation protrusion 121 and the fixed ring Water tightness is formed between the main mounting projection 121 and the main water pipe 10 to prevent tap water from leaking.

The sub connection pipe 130 is connected to the sub connection pipe 130 in a state where the main pipe 10 is installed in the main connection part 120 and the sub pipe pipe 20 is drawn into the sub connection part 130, And the water pipes 20 are compressed and fixed using a compression device so as to have watertightness.

The branched connection pipe 140 is also drawn into one side of the branch pipe 30 and the branch connection pipe 140 of the branch connection pipe 140 is pressed onto the branch pipe 30 by using a compression bonding device, Tightness between the branch connection pipe (140) and the branch pipe (30) by the fixing ring (200).

When tap water is supplied to the main water pipe 10 in a state where the T-branch pipe 100 of the present invention is connected to the main water pipe 10, the sub water pipe 20 and the branch water pipe 30 as described above, 120 into the branch pipe body 110. [

The tap water flowing into the branch pipe body 110 is stagnated because the inclined sill 151 of the pressure generating part 150 is formed to be gradually narrowed in diameter, So that tap water can be easily supplied to the branch water pipe 30 connected to the branch connection part 140.

As described above, tap water is smoothly supplied to the branch pipe (30) connected to the branch connection part (140) by the congestion of the tap water as described above, so that the problem that occurs in the conventional T- It is possible to solve the problem that the supply of tap water is not smooth.

As described above, according to the present invention, the tap water is stagnated inside the branch pipe 100, so that a certain pressure acts on the side where the tap water is branched. Therefore, the inflow of tap water into the branch pipe 30 connected to the branch connection part 140 The water pressure of the tap water is low, and the tap water does not come out. ', And so on.
