Hole for piping branch

The present invention relates to a hole saw used in a pipe branching operation connecting a main pipe through which a fluid such as gas, a chemical material, or water and sewage flows, and a branch pipe provided to a place requiring the fluid. More specifically, after drilling the main pipe, it is possible to take out the cut part of the main pipe and the cutting powder generated during the drilling to the outside, which hinders the flow of fluid by remaining the cut part and the cutting powder in the main pipe. It relates to a hole for pipe branch to prevent the phenomenon.

Most households use city gas, and most buildings and houses use city gas as a fuel for heating, so the gas pipes for supplying city gas from city gas factories are cobwebs in the inhabited areas. It is excreted like

In addition, the ground of the residence is buried with water pipes as well as gas pipes. In addition, pipes for transporting chemicals are disposed in the manufacturing plant of chemicals.

The main pipe through which a fluid such as gas, chemical material or water and sewage flows, and a branch pipe installed to a place requiring the fluid, are connected to each other by using a branching tee so as to use the fluid at the place of use.

For example, if the fluid is a gas, in order to supply city gas from the main pipe to the building or house, which is the final place of use, in general, the branch pipe connecting the main pipe to the building and the house is first disposed and then the final work is performed. Connect main pipe and branch pipe using branching tee.

Thus, the pipe branch work which connects a main pipe and a branch pipe is performed by the following procedures.

(1) As shown in FIG. 1, the lower portion of the T-type fitting 1 is brought into contact with the main tube 7 to weld the T-type fitting 1 and the main tube 7 to the T-type fitting 1. The outlet part 5 and the branch pipe 6 are welded.

(2) And after installing the intermediate shut-off valve (4) in the upper portion of the flange (2), the perforator (8) is installed in the upper portion of the intermediate shut-off valve (4).

(3) After opening the intermediate shut-off valve 4, lower the hole (9) of the punching machine (8) toward the main pipe (7) and rotate the hole (9) to drill the main pipe (7).

(4) The hole (9) of the punching machine (8) is pulled up into the drilling base body.

(5) Close the intermediate shutoff valve (4) and remove the perforator (8) from the intermediate shutoff valve (4).

(6) Remove the hole 9 from the drive shaft 8a of the drill 8, and instead connect the plug adapter 8b and plug 3 as shown in Fig. 2 to the end of the drive shaft to drill the drill 8. To the intermediate shut-off valve (4) again.

(7) With the intermediate shut-off valve 4 open, rotate the drive shaft to screw the plug 3 into the central threaded hole of the flange 2.

(8) The drive shaft of the puncher 8 is lifted up to remove the plug adapter 8b from the plug 3 and the puncher 8 is removed from the intermediate shut-off valve 4.

The conventional pipe branching method of connecting the main pipe 7 and the branch pipe 6 by the above procedure has the following problems.

As shown in FIG. 3, the hole chuck 9 screwed to the drive shaft 8a of the drilling machine 8 is only for drilling the main duct 7, and the main duct 7 is formed by the hole chuck 9. Not only the cutting powder generated when boring remains in the main tube 7 but also the cut portion remains in the main tube 7 after the drilling operation is completed.

As such, after the completion of the pipe branching operation, the cut portion and the cutting powder of the main pipe 7 remain in the main pipe 7, which hinders the flow of the fluid.

For example, a large cut part travels inside the main pipe (7) and blocks it somewhere, causing a large impediment to the flow of the fluid, or blocking the part where a used device such as a pressure control valve is installed to prevent its function. . If the pressure of the fluid is not properly controlled, there is a high risk of fluid leakage due to excessive pressure of the fluid.

And small particles are likely to flow with the fluid, reducing the quality of the fluid or blocking the nozzles from which the fluid is finally discharged. For example, if the fluid is a gas, the cutting block blocks the nozzle of the stove, weakening the flames of the stove, and in severe cases, damaging the nozzle, making it impossible to use the stove.

Therefore, when drilling the main pipe 7 by the hole 9, it is preferable to discharge the cutting powder and the cut part to the outside, but the conventional hole 9 is not provided with any means for performing this function. There was this.

The present invention was devised to solve the above-mentioned problems of the prior art, and the pipe branch which can discharge the cutting powder and the cut portion of the main pipe generated when drilling the main pipe during the branching process of the pipe to the outside. The purpose is to provide a dragon holder.

Piping branch hole 배관 of the present invention for achieving the above object is an adapter having a drive shaft connecting means for connecting the drive shaft of the perforator, a cylindrical top portion connected to the adapter, is connected to face downward in the center of the adapter It characterized in that it comprises a drill projecting downward than the lower end of the saw portion, and a magnet coupled to the inside of the saw portion.
