Description

Water supply system and water supply method for equally distributing the flow rate of a plurality of final water supply points in a building

The present invention relates to a water supply system and method for equally distributing the flow rate of a plurality of final water supply points in a building, and more particularly, to each discharge end of a secondary distributor connected to a plurality of final water supply points groups in a building. By installing a flow control means having an orifice function in the water flow rate equal distribution water supply system and water supply system in which the amount of water discharged from the faucet of each final water supply point in the building can be equalized regardless of the length deviation from the water meter. It's about how.

A water supply system that supplies water from a waterworks or boiler to bathrooms, verandas, sinks, etc. is essential for buildings. To this end, a pipe is required, and currently, the most frequently used method is a water exhaust method in which water is supplied to a final target water supply point, for example, a faucet or a boiler through one or more distributors installed in the pipe.

As shown in FIG. 1 and FIG. 2, in this water exhaust method, the water supplied from the water supply point (water meter) is passed through one distributor to the final water supply point connected to the distributor, such as a bathtub, shower, washbasin, toilet, sink, balcony, etc. As shown in FIG. 3, a plurality of distributors are installed on the ceiling of bathroom 1 and bathroom 2 to distribute the water supplied from the water supply point (water meter) to each of the distributors and the shortest It can be classified as a 'ceiling-mounted water exhaust system' that distributes water to the final water supply points such as bathtubs, showers, sinks, toilets, sinks, and balconies connected to the street.

However, in the case of using the one-to-one water exhaust method or ceiling-embedded water exhaust method as described above, since each distributor and each final water supply point are directly connected to each other, the length of the pipe is long when the distance to the final water supply point is long. As a result, an increase in construction cost and interference between other processes may occur. In addition, there is a problem that an imbalance in flow rate between a water supply point having a short pipe length and a water supply point having a long pipe length (flow rate is concentrated toward a short pipe length) may occur.

In order to solve the flow rate imbalance problem of the above-described water drainage method, a new technology known as a 'wall-embedded open hydrant system' such as a multi-stage branching water supply system and a multi-stage branching water-saving faucet has been proposed. 4 and 5 show piping layouts constructed using the conventional wall-embedded open hydrant method, and FIG. 6 shows an exploded perspective view of a wall-embedded open hydrant installed by being embedded in a retaining wall or masonry wall of a building. However, in the case of such a wall-embedded open faucet box method, the faucet box is embedded in a retaining wall or masonry wall for each faucet location and the pipe jumps from side to side, thereby reducing the flow rate concentration phenomenon that occurred in the existing water drainage method to some extent. However, when using the wall-embedded open hydrant box method, the additional cost of box embedment caused another problem of increased construction cost and increased construction period.

In addition, during actual operation, it was concluded that it was virtually difficult to secure a constant flow rate in the entire faucet with a pressure of 2.5 kgf/cm2g according to the Water Supply Act. For example, in the case of the shower faucet in bathroom 2, which is generally the farthest from the water meter, many sites have suffered from complaints of lack of flow due to a drop in water pressure when used simultaneously with the middle faucet of the pipe connected together.

Therefore, the present invention is to solve the above problems, the flow solim phenomenon that occurs in both the conventional water exhaust method and the wall-embedded open hydrant box method, and when two or more faucets are used at the same time, the farther the faucet from the supply unit is, the more In order to solve both the problem of the decrease in the amount of water discharged and the problem of the increase in construction cost occurring in the wall-embedded open faucet box method, a different resistance coefficient according to the coil length deviation of each faucet is used in the water drainage method, In order to have a constant resistance coefficient for each faucet, it is necessary to add an orifice function to the PB sleeve (Polybutylene Sleeve) so that the amount of water discharged from each faucet can be equal regardless of the length deviation from the water meter. The present invention is to provide a flow control type sleeve having an orifice structure to achieve this object.

However, these tasks are illustrative, and the scope of the present invention is not limited thereby.

In the water supply system 1 for equally distributing the flow rate to a plurality of final water supply points in a building according to an embodiment of the present invention, the plurality of final water supply points are grouped into a plurality of final water supply points (A, B, C, .. .), and the water supplied from the water supply source 10 located outside the building is distributed by the primary distributor 30 to a plurality of final water supply source groups (A, B, C, ...) transfer The primary distributor 30 and the plurality of final water supply points groups A, B, C, ... are connected by a plurality of primary distribution pipes 40a, 40b, 40c, ....

The plurality of final water supply points groups (A, B, C, ...) may set final water supply points disposed in the same or adjacent spaces within a building as one group. For example, as shown in FIG. 7, in the space where 'toilet 1' is arranged (section A), a bathtub (A-1), a sink (A-2), and a toilet (A-3) are grouped together. can be set; In the space where 'toilet 2' is located (section B), a shower (B-1), a sink (B-2), and a toilet (B-3) can be set as one group; In the space where the 'laundry room' is arranged (section C), the boiler (C-1), washing machine faucet (C-2), and hand washing faucet (C-3) can be set as one group. In addition, the final water supply point group may be set in a different form according to the layout design of the use space of the building.

In the plurality of final water supply points groups A, B, C, ..., the water supplied from the primary distribution pipes 40a, 40b, 40c, ... is supplied to a plurality of final water supply points A- 1, A-2, A-3; B-1, B-2, B-3; C-1, C-2, C-3; ...) secondary distributors (50a, 50b, 50c, ...) are installed. In addition, at the discharge ends 510a, 510b, 510c, ... of the plurality of secondary distributors 50a, 50b, 50c, ..., a plurality of final water supply points A-1, A-2 , A-3; B-1, B-2, B-3; C-1, C-2, C-3; ...) to equalize the amount of water transferred to the flow control means (60a, 60b, 60c, ...) are installed.

The flow control means (60a, 60b, 60c, ...) is the final water supply points (A-1, A-2, A-3; B-1, B-2, B-3; C-1, C -2, C-3; ...) and the water supply point (10) in order to solve the problem of imbalance in flow rate due to the length deviation, the water supply point (10) and the final water supply point (A-1, A-2, A -3; B-1, B-2, B-3; C-1, C-2, C-3; ...) The resistance coefficient is different for each faucet in inverse proportion to the length.

And when the two final water supply points are used at the same time, when the bathtub faucet and the kitchen faucet are used at the same time, the flow rate of the bathtub faucet is 5.8 LPM and the flow rate of the kitchen faucet is 4.0 LPM; When the kitchen faucet and shower faucet were used simultaneously, the flow rate of the kitchen faucet was 4.1 LPM and the flow rate of the shower faucet was 6.3 LPM. In the prior art, when two final water supply points are used at the same time, the flow rate reduction of the kitchen faucet where the flow resistance is set to be the largest appears much larger, but in the flow rate equal distribution water supply system and method of the embodiment of the present invention, each final water supply It can be seen that the rate of decrease in flow rate at each point is generally uniform.

And when the three final water supply points are used at the same time, when the kitchen faucet, the washing machine faucet, and the shower faucet are used at the same time, the flow rate of the kitchen faucet is 3.5 LPM, the flow rate of the washing machine faucet is 9.1 LPM, and the flow rate of the shower faucet is 5.0 LPM. ; When the bathtub faucet, kitchen faucet, and washing machine faucet are used at the same time, the flow rate of the bathtub faucet is 5.2 LPM, the flow rate of the kitchen faucet is 3.6 LPM, and the flow rate of the washing machine faucet is 8.5 LPM. It was found that the flow rate decreased evenly. In the prior art, when the three final water supply points are used at the same time, the flow rate reduction of the kitchen faucet where the flow resistance is set to the greatest is much larger (the flow rate concentration phenomenon occurs severely), but the flow rate of the embodiment of the present invention is equally distributed. In the system and method, it can be seen that the rate of decrease in flow rate at each final water supply point was substantially uniform.

As described above, according to the water supply system and method for equally distributing the flow rate to a plurality of final water supply points in a building according to an embodiment of the present invention, even if two or three final water supply points are used at the same time, the flow resistance is small. The flow rate is biased towards the side, so the flow rate decrease rate is small, and the flow rate decrease rate is large on the side with high flow resistance (eg, kitchen faucet). As shown in FIG. 15, at each final water supply point It was found that the flow rate of was reduced approximately equally.

The present invention described above is not limited by the foregoing embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible within a range that does not deviate from the technical spirit of the present invention. It will be clear to those who have knowledge of
