Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conduit tool and a conduit method for removing clogging of a drain pipe and penetrating the drain pipe.

[0002]

2. Description of the Related Art Generally, when a drain pipe is clogged at home or the like,
The wire is inserted into the drainpipe to clear the blockage. However, when the wire is used in such a manner, when the wire is pulled out, sewage may drop and pollute the surroundings.
In addition, the reach distance of the wire is fixed, and is often short. In addition, the wire may be weak in bending of the drainage pipe and may not proceed from the bent portion.

[0003] Therefore, a tube fitting 51 as shown in FIG.
Is used. The passage tool 51 is a tool to be inserted into the opening 20 of the drain pipe 19 from which the clog 21 is to be removed. A donut-shaped rubber ring 55 is sandwiched between the washers 53 and 54 from both sides.
4 is tightened with bolts 52 and wing nuts 56.
As a result, the rubber ring 55 is elastically deformed radially outward to expand the diameter, and is tightly sealed to the inner peripheral surface of the drain pipe 19 so as to be sealed.

[0004]

However, in the drainage pipe 19 which is exposed at a deep position (for example, 800 mm or more in depth) from the ground 23 in a narrow meeting room box 24 (for example, one side of the opening is about 300 mm), a hand , It was difficult to operate the conventional tube fitting 51, and the plug could not be sealed. Further, unless the water pipe 19 for injecting water into the drain pipe 19 is connected to the drain pipe 19 connected in advance, there is no point in using the passage tool 51.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has a pipe fitting and a pipe which can easily and surely remove clogs and pass through a drain pipe. The purpose is to provide a tube method.

[0006]

In order to achieve the above-mentioned object, according to the present invention, there is provided a tube fitting having a pipe body having a tip inserted into an opening of a drain pipe for removing clogging, and a pressurizing apparatus. A liquid guide pipe connected to the pipe for introducing liquid into the drain pipe, and provided on the outer periphery of the distal end of the pipe, expands radially outward in the pipe body by the introduction of the compressed fluid, and is formed inside the drain pipe. And a bag closely contacting the peripheral surface.

In addition, an air guide tube for introducing a pressurized gas into the drain pipe is connected to the pipe.

In the pipe passing method according to the present invention, the pipe body of each of the above-mentioned pipe passing tools is inserted into an opening of a drain pipe for removing clogging, and the bag body is expanded by introducing a compressed fluid. After the gap between the outer peripheral surface of the pipe and the inner peripheral surface of the drain pipe is sealed by contacting the inner peripheral surface of the drain pipe, the pressurized liquid from the liquid guide pipe is introduced into the drain pipe from the pipe body.

Further, in the above method, a pressurized gas is introduced into a drain pipe into which the pressurized liquid has been introduced.

Further, in each of the above methods, ice pieces are put into the drain pipe before inserting the pipe into the opening of the drain pipe.

[0011]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a configuration diagram showing a pipe fitting according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view of a main part showing a state where the pipe fitting is inserted into a drain pipe. In each of the drawings, a tube fitting 1 according to this embodiment includes a cylindrical tube 12 that is horizontally arranged, and a cylindrical vertical tube 5 that is erected in communication with the tube 12. ing. The pipe 12 has a tip 3 inserted into the opening 20 of the drain pipe 19. In the vicinity of the rear end opening 4 of the pipe 12, a cock 6 for stopping water is provided.
Is provided. A cock 7 for stopping water is also provided at the upper end of the vertical pipe 5. The upper end of the vertical pipe 5 is connected to the liquid guide tube 22 via a hose 16 and a faucet 18 fixed by fixing bands 17, 17, respectively. The vertical pipe 5 between the cock 7 and the pipe 2 is connected to the air guide pipe 12 for introducing the pressurized gas A into the drain pipe 19. The cock 13 provided in the air guide pipe 12 is configured to be able to switch the flow path toward the outside world or toward the fluid transport means 15.

On the outer periphery of the distal end portion 3 of the tube 2, a compressed fluid L
The bag body 9 which expands by the introduction of is fixed. The bag 9 is made of an elastic material such as synthetic rubber. Further, the bag body 9 is connected to a fluid transport means 14 for sending the compressed fluid L via a conduit 10 having a cock 11 in the middle. A retaining ring 8 for preventing the bag 9 from falling off from the distal end portion 3 when inflated is fixedly provided near the distal end portion 3 on the outer periphery of the tube 2.

Next, a method of passing the drain pipe 19 by the passing tool 1 will be described with reference to FIGS. 3 and 4. FIG. In this case, the drain pipe 1 for removing the clog 21
Reference numeral 9 denotes an example in which the opening 20 is exposed at a position deep from the ground 23 in the meeting place square 24. First, an appropriate amount of ice pieces 25 and sponge pieces 26 are put through opening 20 into drain pipe 1.
9 (step P1 (FIG. 3), FIG. 4).
(A)). Next, the tip 3 of the pipe 2 is inserted into the opening 20 of the drain pipe 19 (step P2 (FIG. 3), FIG. 4B).
Then, the cock 11 is opened, and the compressed fluid L (here, for example, the pressure is about 1.8 to 7.0 (average about 3.0) k) from the fluid transport means 14 (for example, an air compressor)
g / cm ² of compressed air) is introduced into the bag space 9 a of the bag body 9. Thereby, the bag body 9 expands radially outward of the pipe body 2 and closely adheres to the inner peripheral surface of the drain pipe 19 (step P3 (FIG. 3), FIG. 4C). In this manner, the gap 20a between the outer peripheral surface of the pipe 2 and the inner peripheral surface of the drain pipe 19 is sealed.

Subsequently, when the flow passage of the cock 13 is opened to the outside and the faucet 18 and the cock 7 are opened, the pressurized liquid W (here, for example, when the pressure is 0.2 kg / cm ² of about tap water was used) is a vertical tube 5
Through the pipe 2 and into the drain pipe 19 (step P4
(FIG. 3), FIG. 4 (d)), and accordingly, the air in the drain pipe 19 is discharged from the cock 13 to the outside. By the way, if the clog 21 is soft,
The clog 21 may be removed by being pushed away in the direction of the arrow 27 by the liquid pressure (step P7 (FIG. 3)). On the other hand, when the clog 21 is stubborn, the clog 21 is not removed only by introducing the pressurized liquid W. In that case, drain pipe 19
After the inside is filled with the pressurized liquid W, the cock 7 is closed. Then, the flow path of the cock 13 is changed from the outside to the fluid transport means 15.
(For example, air compressor) side. Then, the pressurized gas A sent from the fluid transport means 15 (here, for example, the pressure is about 1.8 to 7.0 (about 3.0 on average)) is placed in the drain pipe 19 filled with the pressurized liquid W. kg / cm ²
Degree of compressed air) is introduced (step P5).
(FIG. 3), FIG. 4 (e)). Thereby, in most cases, the clog 21 is swept away by the high gas pressure (step P7).

If the clogging 21 still cannot be removed, the cock 13 is closed to stop the introduction of the pressurized gas A, and the cock 6 is opened. Thereby, the pressurized gas A in the drain pipe 19
And the pressurized liquid W flows in the opposite direction to the previous pressing direction and is discharged from the rear end opening 4 (step P6 (FIG. 3),
FIG. 4 (f)). Then, due to rapid pressure reduction, clogging 21
Collapses and the pressurized liquid W is discharged from the rear end opening 4 together. On the other hand, the clog 21 may become soft even if it does not collapse in the process P6. Then, when the liquid introduction step 4 and the gas introduction step 5 are repeated again, clogging 21
Is reliably removed.

As described above, the tube fitting 1 according to the present embodiment and the tube fitting method using the same have the advantage that even if the drain pipe 19 is deep enough to be out of reach, the vertical pipe body 5 can be removed. As long as the end 3 of the pipe 2 is inserted into the opening 20 of the drain pipe 19, the cocks 7, 11,
13 only needs to be opened and closed. Thereby, the opening 20 of the drain pipe 19 is sealed by the bag body 9 swelled with the compressed fluid L, and the pressurized liquid W and the pressurized gas A are introduced into the drain pipe 19.

Accordingly, the drainage pipe 19 can be easily, quickly, or reliably passed through at home. Further, even when the distance from the opening 20 of the drain pipe 19 to the clogging 21 is long or the drain pipe 19 has a bent portion, the pressurized liquid W alone or the pressurized liquid W and the pressurized gas A Has little effect on the clog clearing operation.

In addition, prior to the insertion of the pipe 2 into the opening 20, the ice pieces 25 are put into the drain pipe 19, so that the small gap that can be present in the clog 21 and that can leak water is removed. At the time of pressurization, the ice pieces 25 and the sponge pieces 26 are closed to reduce pressure loss. In particular, the sponge pieces 26 are rich in elasticity and contain water, which makes it difficult to ventilate them.
Sufficiently close the small gap. And after use, ice pieces 25
Since it melts into harmless water, there is no need for post-treatment. Further, there is an advantage that the ice pieces 25 can be easily procured in any home.

The shape and connection of the tubular body and the vertical tubular body of the present invention are not limited to those of the above-described embodiment. On the other hand, as the pressurized liquid of the present invention, it is easily available,
Water is most preferable from the viewpoints of low cost, safety, easy post-treatment, and the like. However, other than water, for example, vegetable oil, glycerin, ethylene glycol, and other liquids may be used. The compressed fluid of the present invention may be, for example, nitrogen gas, carbon dioxide gas, water, vegetable oil, glycerin, ethylene glycol, or the like, in addition to air. As the pressurized gas of the present invention, for example, nitrogen gas or carbon dioxide gas can be used other than air.

[0020]

As described above, according to the conduit tool and the conduit method according to the present invention, even if the drain pipe is inaccessible, only the tip of the pipe is inserted into the opening. You can operate it on the ground. This allows
The opening of the drainage pipe can be sealed by the bag body which is inflated with the compressed fluid, and even if the drainage pipe does not have a dedicated water guide pipe (for example, indicated by reference numeral 57 in FIG. 5), the pressurized liquid is introduced into the pipe. Or pressurized gas can be introduced. Therefore, even at home, the drainage pipe can be easily, quickly, and reliably inserted. Even if the distance from the opening of the drainage pipe to the clogging is somewhat long, or if the drainage pipe has a bent part, the action of the pressurized liquid alone or the action of the pressurized liquid and the pressurized gas The clog can be removed.

Further, in the above-mentioned pipe-passing tool and the pipe-passing method, when the pressurized gas is introduced from the air guide pipe into the drain pipe into which the pressurized liquid has been introduced, a higher pressure can be obtained. Can be reliably removed.

In the above-mentioned pipe passing method, if ice chips are previously introduced into the drainage pipe before the pipe body is inserted, the small gaps that can leak and exist in the clogging are closed by the ice pieces when pressurized. Pressure loss is reduced. On the other hand, the used pieces of ice melt and become harmless water, so that there is no need for post-treatment.
