The present invention relates to a structure of a hot water pipe into which a heating wire is inserted, and more particularly, a heating wire capable of accommodating water hammer such as an increase in pressure inside the hot water pipe can prevent damage to the hot water pipe and the sealing device. It relates to the structure of the inserted hot water pipe.

In general, a number of devices that use electric power to heat the heating wire is inserted into the interior of the hot water pipe. (Refer to Utility Model Registration No. 20-0405681.) It is no exaggeration to say that the lifetime of the heating system is determined by how to prevent the leakage of the heating water inserted into the heating system.

That is, "a" and "b" of FIG. 1 are schematic sectional views showing a part of the structure of a hot water pipe in which a conventional heating wire is inserted.

Referring to the drawing, first, "A", the heating water and the heating wire 14 is inserted into the inside of the hot water pipe 12, the end portion is provided with a sealing device 20 to prevent the heating water leakage have.

The sealing device 20 has a spiral portion formed therein and a nut 22 which is fastened so as not to be separated from an end portion of the hot water pipe 12 and one side of the first spiral to be fastened to an inner spiral portion of the nut 22. And a sealing cap 24, 24 ′ and a sealing cap 24, 24 ′ fitted to the inside of the connecting piece 23 and the connecting piece 23 formed with a second spiral part on the other side to be in close contact with each other. It comprises a cap nut 26 for fastening and a cap 28 for blocking the end of the cap nut 26. In addition, the sealing caps 24 and 24 'are formed in a rhombus shape and face each other, and a ring washer 25 is positioned at an intermediate ground surface thereof.

Of course, various types other than the above-mentioned sealing device 20 have been proposed, and all of them have the same purpose as being provided to tightly block the ends of the hot water pipes 12.

In the structure 10 of the conventional hot water pipe configured as described above, when power is applied to the heating wire 14 discharged to the outside, the heating water is heated by the heating wire 14 to be heated. At this time, if the heating in the above manner for a long time will increase the pressure by the heating water.

Here, referring to "b", a part of the hot water pipe 12 is damaged due to the water hammer of the pressure-increased heating water. That is, considering that the hot water pipe 12 is made of a synthetic resin pipe having a relatively thin thickness in order to achieve heating, it is damaged by water hammer caused by excessive pressure rise.

The present invention is devised to solve the above problems, it can accommodate the water hammer phenomenon such as the pressure rise inside the hot water pipe of the hot water pipe inserted with a heating wire that can prevent the damage of the hot water pipe and the sealing device We want to provide a structure.

In order to achieve the above object, the present invention is provided with a water hammer to accommodate the water hammer phenomenon due to the pressure rise of the hot water pipe by the pressure chamber in which the filling material is injected into one side of the sealed device to the hot water pipe.

Preferably, the water hammer is provided with a fastening means that is fastened to the sealing device to the hot water pipe at the upper end, and is installed to partition the inside of the casing and the casing formed with an inlet through which various fillers can be injected, It is configured to include a diaphragm having.

In addition, instead of the diaphragm is provided with an air bag directly connected to the inlet formed in the lower end of the casing.

Hereinafter, with reference to the accompanying drawings will be described in more detail the structure of the hot water pipe is inserted the heating wire of the present invention.

Figure 2 is a schematic cross-sectional view showing a part of the structure of the hot water pipe is inserted according to a preferred embodiment of the present invention, Figure 3 is an exploded perspective view of a water hammer according to a preferred embodiment of the present invention.

Looking at the structure 100 of the hot water pipe according to the present invention with reference to the drawings, the water heater 12 and the heating device 14 inserted therein, the sealing device for sealing the end of the hot water pipe (12) ( 20) and one side of the closure device 20 can be seen that it comprises a water hammer preventer 110 is fastened through the fastening means 114.

Here, since the hot water pipe 12 and the sealing device 20 has the same structure as the prior art, a detailed description thereof will be omitted.

Therefore, looking at the configuration of the water hammer preventer 110, it can be seen that comprises a large casing 112 and the diaphragm 120 installed inside the casing 112.

The casing 112 has a fastening means 114 is fastened to the sealing device 20 is formed at the upper end, the lower end is preferably formed with an injection hole 116 for injecting various fillers. Here, the filler includes a gas that is a compressive fluid such as air, inert gas, and nitrogen. In addition, the fastening means 114 is preferably composed of a conventional flange or nipple.

The diaphragm 120 is installed inside the casing 112 and provided to partition the casing 112, but has a self-elastic force. At this time, the diaphragm 120 is preferably tightly coupled between the casing 112 to withstand the pressure.

The water hammer preventer 110 configured as described above is a kind of pressure chamber 122 disposed in the lower side of the casing 112 partitioned by the diaphragm 120 by injecting the filler at a predetermined pressure through the injection hole 116 provided at the lower end of the casing 112. Will form.

On the other hand, it is apparent that the water hammer preventer 110 may be installed on one side of the hot water pipe 12 through the fastening means 114 similarly to the sealing device 20.

Figure 4 is a schematic cross-sectional view showing a water hammer according to another embodiment of the present invention.

Referring to the drawings, it can be seen that the airbag 124 is provided in place of the diaphragm 120 provided inside the water hammer. At this time, the airbag 124 is preferably implemented to be directly connected to the inlet 116 so that the filler can be injected therein. The connection method of the injection hole 116 will not be described in more detail because it is typically implemented in automobile tires.

As the filler is injected into the airbag 124 configured as described above, the airbag 124 serves as the pressure chamber 122 defined by the diaphragm 120.

At this time, when the pressure is discharged from the hot water pipe 12, the filler injected into the airbag 124 absorbs this pressure. At this time, the airbag 124 becomes flat due to the pressure and then the pressure is lowered. It will be expanded again by the filler.

Figure 5 is a schematic operation of the structure of the hot water pipe according to an embodiment of the present invention.

Referring to the drawings, the inner upper side of the casing 112 partitioned by the diaphragm 120 is in direct communication with the hot water pipe 12 and the fastening means 114, the lower side is filled with a filler is filled in the pressure chamber 122 To form.

At this time, if the pressure in the hot water pipe 12 is increased, this high pressure will be introduced into the water hammer prevention device (110). As the high pressure flows in, the diaphragm 120 expands in the dotted line direction while receiving the same. On the other hand, if the pressure in the hot water pipe 12 is lowered, it will be restored to the solid line again.

At this time, it is too obvious that the pressure in the pressure chamber 122 can be implemented differently as necessary.

As a result, according to the structure 100 of the hot water pipe according to the present invention, the water hammer preventing device 110 in which the pressure chamber 122 is formed by the diaphragm 120 or the air bag 124 may be formed of the hot water pipe 12 or the sealing device 20. It is provided on one side and has the advantage of preventing the breakage of the hot water pipe 12 by accommodating the pressure of the heating water, that is, the water hammer phenomenon, as well as the structure of the water hammer preventive 110 is easy to install and follow-up management There is one advantage.
