On the other hand, in order to save construction costs, when using an industrial pump made of iron material, the rust may occur in household water and noise may occur, so it is necessary to pay attention.

The water meter 300 may include a cap 310, a meter box 320, an inflow pipe 330, a water supply pipe 340, a meter 350, and a control valve 360.

As described above, the water meter 300 is installed on the ground of the building, the first floor / underground machine room, etc., and is a central meter (outdoor meter) for measuring the inflow of water from the water supply 100, and is used to prevent freezing and damage. For this purpose, it may be embedded in the ground of a building, the ground floor / underground machine room, or the like.

Cap 310 may be a cover to cover the metering box 320, the metering box 320 to accommodate the inlet pipe 330, the water supply pipe 340, the meter 350 and the control valve 360 Can be. On the other hand, when the water meter 300 is buried, the cap 310 may be exposed to the outside, the meter box 320 is buried mostly can be safely protected.

Inflow pipe 330 is mostly disposed inside the metering box 320, a portion of which may be exposed to the outside and connected to the water supply (100). The water supply pipe 340 is mostly disposed inside the metering box 320, and a part of the water supply pipe 340 may be exposed to the outside to be connected to the bottom up pipe 400.

Meter 350 may be a meter disposed between the inlet pipe 330 and the water supply pipe 340 to measure the flow rate, the control valve 360 is disposed in the water supply pipe 340 of the water supplied to the building The water supply pressure can be controlled.

That is, the water of the tap water 100 passes through the inflow pipe 330, is measured by the measuring instrument 350, and the water supply pressure is adjusted by the control valve 360 in the water supply pipe 340, and the upward pipe 400 is connected thereto. Can be moved to individual rooms of the building.

On the other hand, even if the water supply pressure is adjusted to the maximum through the control valve 360, the water supply pressure may not be lower than the reference value (design condition). As described above, when the water supply pressure is not sufficiently secured, in the building water supply boosting system 1000 of the present invention, the pump 200 may be directly installed in the pipe of the water meter 300 to boost the water supply pressure.

In this case, the pump 200 is disposed inside the metering box 320 and covered by the cap 310 (safe protection and freeze protection of the pump), and connected to the water supply pipe 340 to boost the water supply pressure. have.

To this end, for example, the pump 200 disassembles the water supply pipe 340 to install the link 370-1, and the pump 200 and the supply tube (not shown) and the discharge tube (not shown). By connecting the link 370-1, it may be connected to the water supply pipe 340. That is, the water is supplied to the pump 200 through the supply tube in the link 370-1, and then boosted, and then discharged back to the link 370-1 through the discharge tube, and the pressurized water of the link 370-1. Is controlled by the control valve 360 is to be moved to the upward pipe 400 through the water supply pipe 340.

According to the above, the building water supply boosting system 1000 of the present invention provides a system capable of boosting the building water supply by installing only the pump 200 without a separate installation by a simple construction method.

According to an embodiment, the pump 200 may be disposed outside the metering box 320. For example, due to the internal structure of the metering box 320 or the devices already provided in the metering box 320, there may be insufficient space for the pump 200 to be disposed. In this case, the pump 200 may be disposed in a specific space outside of the metering container 320, and the position thereof is not limited.

Alternatively, the diameter / pipe area of the feed tube may be larger than the diameter / pipe area of the discharge tube). That is, since the cross-sectional area of the portion connected to the supply tube in the link 370-1 is increased, the speed may be reduced by the Bernoulli's law, but the pressure may be increased. Accordingly, the boosted water is supplied to the pump 200 to supply the pump. In order to supply water to the 200 (to hold water to the pump), there is an advantage of increasing the efficiency of the pump 200 by supplying water of sufficient pressure.

In addition, another modification (not shown) of the building water supply boosting system 1000 of the present invention includes a generator that is connected to the rotary shaft of the pump 200 to generate power, and a heating wire is connected to the generator to supply and discharge tubes. It can be built in. Since the pump 200 is disposed externally in the metering box 320, the supply tube and the discharge tube may be vulnerable to freezing. In the building water supply boosting system 1000 of the present invention, the supply tube and the discharge tube are pump 200. Power generated by the generator's self-powered by) may be heated by a heating wire to prevent freezing.

In one embodiment, the building water supply boosting system 1000 may include measuring means (sensors) for measuring the water temperature inside the supply tube and the discharge tube. Accordingly, when the water temperature in the supply tube and the discharge tube is lowered below the preset temperature, the building water supply boosting system 1000 may heat the supply tube and the discharge tube by using a heating wire.

In another embodiment, the building water supply boosting system 1000 may measure the operation of the pump 200 and thus the water pressure in the discharge tube and the speed of the water. In one embodiment, the building water supply boosting system 1000 is that when the water pressure and the speed of the water is measured outside the expected range according to the operation of the pump 200, the water in the discharge tube is frozen and the diameter of the discharge tube is narrowed By judging and melting it, the discharge tube can be heated to prevent freezing.

The bottom up pipe 400 may provide a flow path for the water measured and boosted by the water meter 300 to move to individual rooms of the building.

Preferably, the pressurized water may be directly supplied to the individual chambers of the building directly through the bottom up pipe 400 (see FIG. 1), but is not limited thereto.

The central electrical installation 500 may be a facility that provides power for operating the pump 200. For example, the pump 200 may receive power from the central electric facility 500 through the leader line 500-2 drawn out separately from the distribution box, the distribution box 500-1, and the like of the building.

On the other hand, the leader line 500-2 is provided in the form of a double corrugated pipe, the cable wire is built-in, the pump 200 of the metering box 320 is fixed to the column by a bracket, etc. neatly buried in the building floor Can be connected.
