JPS5840138Y2 - water pipe - Google Patents

Description

[Detailed explanation of the invention] This invention is based on the idea that in cold regions, water pipes often freeze on cold winter mornings, and it is difficult to take measures to prevent this, and sometimes water pipes burst, resulting in costly repairs. The invention relates to a double-walled water pipe with a hollow structure designed to facilitate treatment in the event that the water pipe freezes.

Conventionally, water pipes are usually installed as iron pipes or with heat insulating material (styrofoam, vinyl tape, hemp, etc.) wrapped around the iron pipes.

Unless you live in a particularly cold region, freezing usually occurs in the water pipes that extend above ground, and ordinary households do not deal with underground water pipes.

Furthermore, even though water pipes are wrapped with antifreeze insulation material, the water pipes are often frozen on cold winter mornings, and the work of wrapping insulation material around water pipes is relatively expensive. .

The hollow water pipe according to the present invention eliminates these drawbacks and is configured so that even if the water pipe freezes, ordinary householders can take immediate action.

Next, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a partial sectional view of an embodiment of the present invention.

Reference numeral 1 in the figure is an ordinary type commonly used in water faucet units, and the installation is done by providing a through hole 3 at one location on the upper part of the flange 2.

4 is a joint between the faucet unit 1 and the water pipe 5.

Reference numeral 6 denotes a guide ring which is attached to the outer periphery of the joint 4 and the water pipe 5 and has a notch, and the outer diameter of the guide ring is configured to match the inner diameter of the pipe 7 to be placed over the outermost part, and the material is plastic. But Styrofoam or anything else will do.

For installation, the flange 2 and pipe 7 are fixed with adhesive to prevent water leakage.

Its cross-sectional shape may be as shown in FIG. 2, or it may be provided with a notch to allow water to pass through.

A pipe 7 made of vinyl chloride is placed over the water pipe 5, and is fitted with a guide ring 6 to prevent rattling between the pipe 5 and the pipe 5, and is hollow inside.

It is sufficient that the gap between the hollow parts is 2 to 5 mm.

The faucet unit 1 is installed so that the hole 3 of the flange 2 is between the joint 4 and the pipe 7, so that the outside and the hollow part 8 inside the pipe 7 are connected.

An inlet 9 is provided in the hole 3 by fixing a pipe upward so that water can be injected.

On the other hand, the pipe 7 that enters the ground 11 at the other end is slightly embedded in the ground or concrete, and one to two small round holes 10 are provided around the pipe 7 at a position slightly higher than the ground 11. Leave some space open.

The effects of the present invention configured as described above will be described.

First, on a cold morning, when the water pipe is frozen and water does not come out even when the faucet is turned on, boiling water is poured into the inlet 9 from the spout on the medicinal surface.

The poured hot water flows into the hollow parts of the water pipes 5 and 7 and warms the water pipes 5, so the frozen water in the water pipes 5 begins to melt and tap water flows out from the faucet.

Although it depends on the length of the water pipe 5, the amount of hot water needed is at most 1 to 2 cups of water per medicinal level.

On the other hand, the poured hot water is at the outlet 1 slightly above the ground 11.
0 to the outside.

As described above, although the present invention is based on a very simple principle, it is more effective than wrapping a heat insulating material around the water pipe 5, and the facility cost is lower, and the construction period is much shorter.

Another effect is that the area around the water pipe 5 is hollow and double layered, so in summer, when you turn on the faucet, lukewarm water comes out, which is not pleasant. The water from the water pipes didn't get too hot, and it had an insulating effect, so I felt very comfortable after using it.

As described above, the present invention not only can quickly treat freezing in winter, but also can be expected to have a moisture-proofing effect that prevents water temperature from rising in summer, and experiments have shown that it is more effective than conventional moisture-proofing materials.

Therefore, the main point of the present invention is to connect the water pipe 5 to another pipe 7.
and maintain a hollow state between the water pipe 5 and the pipe 7.
In addition, a guide ring 6 is appropriately provided to allow water, air, etc. to pass through, and an inlet 9 is provided to allow water to flow near the faucet.
This hollow type water pipe is characterized by having a configuration in which a small hole is bored in the pipe 7 near the ground 11 outside the other end to provide a discharge port.

To explain another embodiment, as shown in FIG. 3, the pipe 7 is installed by installing an injection pipe near the flange, and the injection port 12 is guided outside the wall 13, and the injection port 12 is installed. It may also be a

In this case, there is no need to perform any machining on the faucet unit 1.

The other points are completely the same as the previous embodiment.

The pipe 7 may be a vinyl chloride pipe, but may be made of other materials as long as they are inexpensive and have a high heat retention effect.
