Description

[Detailed Description of the Invention] This invention relates to a control unit that is mainly installed in a domestic water supply system and provides a stable water supply at all times.

In general, domestic water supply is conducted from the water supply pipes of the waterworks bureau, etc. to the ρ water taps in each household via water supply pipes, but each household has a stop valve and a water meter installed underground. For example, if the hose attached to the end of a faucet remains submerged in water in a bathtub, etc., and there is a water outage in the water distribution system, the sewage in the bathtub will back up into the water supply pipe or distribution pipe. This often resulted in inconveniences such as contaminating the water supply or turning the water meter upside down, preventing accurate measurement.

On the other hand, whether the water supply method is a direct connection type, direct water pressure type, or elevated water tank type, the water supply to each unit is directly affected by the water supply pressure, which varies depending on the area where the water is supplied or the upper and lower floors of a high-rise building. In addition to overflowing water from taps or insufficient water flow, water hammer phenomenon occurred in areas with fast water flow, which often caused problems such as damage to water supply equipment such as water meters. be.

In view of these circumstances, this proposal is designed to incorporate water stop valves, water meters, check valves, constant flow valves, etc. into a control unit that can be connected to the water supply pipes of each house. This solves all the inconveniences at once.

Hereinafter, the configuration of the present invention will be explained in more detail based on the embodiment shown in the drawings. 1 is a control unit that is attached to the water supply of each house, and one is connected to the water pipe 3 at two places on the side of the outer box 2. Two connecting vibros, 6', which can be freely connected to the water receiving pipe 4 leading to the water supply pipe 4 and the other connecting to the water supply pipe 4' leading to the hydrant 5, are inserted, and the connecting vibros, 6' inside the outer box 2 are inserted. At least 7 water stop valves and 8 water meters
, a check valve 9 and a constant flow valve 10 are successively connected and compactly incorporated into the outer case 2.

In the figure, 11.11 is the above-mentioned connecting vibro, a joint for connecting the unit 1 which is attached to 6' as appropriate, and 12.13 is a strainer which is attached to the above-mentioned unit 1 as necessary, and a downstream water stop. Shows the stopper.

The main water receiving control unit related to the above configuration is as follows:
To install this in each house, simply connect the connecting vibro, 6', protruding from the side of the outer box 2 to the water receiving pipe 4 on the water pipe 3 side, and the water supply pipe 4' on the hydrant 5 side, respectively. In addition to being extremely easy to install, the constant flow valve 10 built into the control unit equalizes the water supply pressure, and the water volume and water pressure discharged from the faucet 5 are stable with no excess or deficiency, ensuring a constant water supply at all times. Not only is this possible, but the water hammer effect can be alleviated and breakdowns of water supply equipment can be significantly reduced.

In addition, the unit 1 of the present invention is equipped with the check valve 9 in advance.
This prevents the backflow of sewage during a water outage, etc., thereby preventing contamination of the water supply, and also reliably prevents the water meter 8 from reversing or malfunctioning due to this.

The proposed unit can be equipped with a strainer 12 as necessary to collect mixed paper and piping chips generated during piping work, etc., and prevent the contamination of drinking water or the above-mentioned foreign materials. It is also possible to completely eliminate malfunctions of the water meter 8 due to blockage.

On the other hand, as shown in FIG. 2, the present control unit 1 can be protected from damage caused by freezing, sunlight exposure, etc. by installing a suitable safety valve 14 between the check valve 9 and the constant flow valve 10. It is possible to reduce the abnormally high pressure in the pipes, which not only reliably prevents damage or malfunction of each pipe and equipment, but also has excellent effects such as being able to significantly downsize the check valve 9 located upstream of the safety valve. It is something to do.

Note that the check valve 9, the constant flow valve 10, and the safety valve 14 can be made into a more compact unit by combining one or two of them into an integral structure.

As stated above, according to the main case control unit,
It is extremely easy to install the water supply equipment on-site, and the functionality and safety of the water supply system from the water pipes 3 to the water taps 5 in each house have been significantly improved, which is completely beyond expectations for conventional domestic water supply facilities. It is the result of excellent practical effects that could not be achieved.
