Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a water drainage piping circuit.

[Prior Art] Conventionally, this type of device is as follows.

It consists of a pipe 5 connecting to the water supply main pipe, an indoor riser pipe 6, an indoor pipe 7 to each water tap, a drain pipe 8 opened underground, a manual valve 9, a manual valve 10, and an air vent valve 11.
In the water draining operation, the manual valve 9 is closed and the manual valve 10 is opened.

Normally, the manual valve 9 is closed and the manual valve 10 is opened at the same time using one handle.

Thereafter, by opening the air vent valve 11, the water is discharged from the drain pipe 8 which is opened underground.

[Problems to be solved by the invention] The conventional techniques described above had the following problems.

In this case, if the air vent valve 11 is not opened, the air sucked in and the water discharged will interfere with each other, making it difficult to drain the water.

The present application was made in view of the problems of the prior art, and its purpose is to provide a system that can do the following.

Even without a special air bleed valve, water in the indoor riser can be easily drained.

[Means for Solving the Problems] In order to achieve the above object, the present invention is as follows.

In other words, in the present application, the main pipe 1 connected to the main water supply pipe is connected via the solenoid valve 1A,
Two systems of drainage pipes 2A1 are connected to the two systems of indoor risepipes 2 and 3, and are opened underground through two systems of solenoid valves 2A and 3A at the lower ends of the two systems of indoor risepipes 2 and 3. , 3A1 are connected to each other, and an indoor pipe 4 to each water faucet is connected to the upper end of the indoor riser pipes 2 and 3 of the two systems.

[Operation] The water draining operation is performed by closing solenoid valve 1A and solenoid valve 2.
When A and 3A are opened, a piping circuit is formed between the upper ends of the indoor riser pipes 2 and 3 opened underground and the drain pipes 2A1 and 3A1.

The water in the indoor risers 2 and 3 sucks air from one direction depending on the resistance, and drains water from the other direction.

Therefore, even without a special air vent valve, water in the indoor risers 2 and 3 can be easily drained.

[Example of idea] Examples will be described with reference to the drawings.

A is the water drain piping circuit of the present invention.

Connect the main pipe 1 to the main water supply pipe via the solenoid valve 1A,
Two systems of drainage pipes 2A1 are connected to the two systems of indoor risepipes 2 and 3, and are opened underground through two systems of solenoid valves 2A and 3A at the lower ends of the two systems of indoor risepipes 2 and 3. , 3A1 are connected to each other, and an indoor pipe 4 to each water faucet is connected to the upper end of the indoor riser pipes 2 and 3 of the two systems.

[Effects of the invention] Since the present invention is configured as described above, it produces the following effects.

Draining water to prevent water from freezing in northern countries is cumbersome, and forgetting to drain the water can cause water to freeze, causing problems in people's daily lives.

In the present invention, in order to eliminate the above-mentioned obstacles, a water draining capability is added to a home security system that is remotely controlled via a telephone line.

Or add water removal capability to central control in your home.
Furthermore, the aim is to enable automatic water draining capability using a temperature sensor.

Even with conventional manual or electric drain valves, water cannot be drained sufficiently unless the air vent valve is opened at the top of the indoor risepipe.

Accidents may also occur due to forgetting to close the air vent valve.

The above-mentioned ability can be achieved by electrifying the electric water drain valve and air vent in the conventional type, but since the water drain valve and air vent valve are usually located far apart, there is a problem in wiring control.

In this invention, by dividing the indoor risepipe into two systems, by switching the solenoid valve, water flows to the side with less resistance, air is sucked in from the other side, and the water in the two-system circuit is quickly released underground. It is discharged from the drain pipe.

In the present invention, it is possible to concentrate the solenoid valves in one place, the water draining device can be made into a unit, and the installation work and control are considered to be effective.
