Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a simple drainage device that is attached to a household water supply device.

[Conventional technology]

If turbid water occurs due to a water outage due to water pipe repair work, a water leakage accident, or the use of a fire hydrant, drain water using the existing drainage system or fire hydrant at the downstream water distribution destination, or discharge it from the faucet in each home. Therefore, the current situation is that treatment of turbid water, etc. is being carried out.

[Problem that the invention attempts to solve]

The above-mentioned method has the problem that it takes time to treat the turbid water and ultimately requires drainage operations in each household, making it impossible to completely treat the turbid water in a short period of time.

[Means for solving problems]

This invention is useful when carrying out planned improvement work on water pipes or when turbid water is predicted to occur in advance.
The purpose of the present invention is to provide a simple drainage device that can be attached to the domestic water supply equipment of each household in the area to easily drain turbid water.

For this purpose, the simple drainage device according to the present invention connects the inlet of the meter box to a pipe connected to a tap water supply source, and connects the outlet of the meter box to a connecting pipe that connects to a faucet in the home. A drainage device for a connected water supply device,
Among a set of bent pipes, one end of which is connected to the inlet and outlet of the meter box, the middle part of the water supply side is branched off, and an on-off valve is provided there, and the other ends of each bent pipe are connected to each other. By bending in the opposite direction, the bent tube can be attached to the water supply device, replacing the meter box of the water supply device.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 designates a meter box for measuring the amount of tap water supplied to a household, and has an inlet portion 1b and an outlet portion 1c protruding from the left and right sides of a main body 1a that houses an impeller, etc.; The opening/closing lid 2 is pivotally attached to the edge of the meter section 1d on the top surface.

Reference numerals 3 and 4 designate a pair of bent tube bodies that are substantially S-shaped when viewed from the front and are arranged symmetrically with respect to the center longitudinal section of the meter box 1;
a and 4a are fixed to each other, and the openings at their upper ends are connected to the inlet part 1b and the outlet part 1b of the meter box 1, respectively.

Therefore, with the meter box 1 at the top and the left and right bent pipe bodies 3 and 4 connected to the left and right entrances and exits 1b and 1c, respectively, the shape is approximately T when viewed from the front.
A frame-shaped flow path is formed.

To be more specific, the left bent pipe 3 that sends tap water to the meter box 1 has a vertical straight pipe 3b connected to the lower end of a horizontally U-shaped upper pipe 3a that opens to the right. A bent pipe 3c, which is U-shaped in front view and opens to the left, is connected to the lower end of the pipe.

Further, a removable coupler 5 is provided at the lower end of the straight pipe 3b, and a three-way valve 6 is provided above the coupler 5.

An on-off valve 7 is connected to the outlet 6a of the three-way valve 6 via a branch pipe 8, and a drain hose 9 is connected to the on-off valve 7.

The right bent pipe 4 that supplies tap water to the home is formed by connecting a vertical straight pipe 4b to the lower end of a horizontal U-shaped upper pipe 4a that opens to the left, and the lower end of this straight pipe 4b. A curved pipe 4c having a U-shape when viewed from the front and opening to the right is connected via a coupler 10 to the curved pipe 4c.

The simple drainage device 11 is assembled by welding these curved pipes 3c and 4c back to back. The length between the inlet and outlet end faces of the curved pipes 3c and 4c of this drainage device 11, that is, the installation length m
is set equal to the installation length n of the meter box 1.

In addition, 12 shown by an imaginary line is a pipe connected to a tap water supply source, and 13 is a connecting pipe connected to a faucet 14 in the home. Usually, there is a meter box (not shown) between the openings of both. is installed.

To use the drainage device 11 according to the present invention, remove the existing meter box (not shown), and connect the inlet sides of the disassembled bent pipes 3c and 4c with the couplers 5 and 10 to the pipe 12, and connect the outlet sides thereof. tube 13
Then, couplers 5 and 10 are used to attach the upper portions of the bent pipe bodies 3 and 4, and the pipes are connected as shown in the figure.

When using tap water, the three-way valve 6 is passed directly through the straight pipe 3b, and the water is distributed to the faucet 14 via the meter box 1.

When turbid water flows, switch the three-way valve 6 to pass it through the branch pipe 8, open the on-off valve 7, and connect the drain hose 9.
Releases turbid water from.

[Modified example]

In the embodiments described above, a new meter box was used for the drainage system, but a meter box removed from an existing water supply system may be incorporated as is.

Moreover, the three-way valve and coupler can also be omitted.

[Effect of idea]

The simple drainage device of the present invention can be installed in advance in a home water supply system in an area where turbid water is predicted to occur, and simply by opening the valve, turbid water can be easily drained.

In addition, when tap water is available, the device can be used as a normal water supply device by simply closing the valve.
