Description

The invention relates to sanitary equipment of a building, namely to a building water supply system.

The purpose of the invention is to reduce operating costs by reducing the cost of electricity and water.

The drawing shows schematically the proposed building water supply system.

The building water supply system includes a common supply pipe 1 with a step-up pump 2 and a storage tank 3, a pipeline 4 connecting the storage tank 3 to a common supply pipeline 1, an electric shutter 5. On

The common supply pipe 1 is connected to the storage tank 3 and 15 is equipped with a flow controller 6 with a throttling device, for example, a diaphragm 7, which is duplicated by the exhaust pipeline 8 with an electric valve 9. A relay 10 is installed in the lower part of the storage tank 3 A level electrically connected to electrically-controlled valves 5 and 9, an air pipe 11 with a non-return valve - flow limiter 12 or a plunger is connected to the upper part of the tank accumulator 3.

On the impulse piping connected to the supply piping 1 to the flow regulator 6, a pressure sensor 13 is installed electrically connected with electric valves 5 and 9 (the impulse lines are shown in dotted lines in the drawing and the electric lines in the dash line).

The system works as follows.

With increased and normal pressure of water in the urban water supply network and water intake in the network less than the estimated water to the system is fed through a common supply pipe I, the storage tank 35 3, which is filled with water at that time. The elevation pump 2 is at this time turned on or off if the water pressure is sufficient to supply water.

With an increase in water intake to a value exceeding that for which the flow regulator 6 is tuned, the pressure loss in the throttle 7 exceeds a predetermined value, and the flow regulator 6 starts to cover, maintaining the water flow in general

flow pipe 1 at a given level.

At this time, due to the suction effect of the booster pump 2, water is withdrawn from the storage tank 3. In this case, the flow restrictor 12 opens and allows air to flow into the tank 3 via line 11. The water level in the storage tank 3 begins to decrease. The capacity of the battery pack 3 is designed in such a way as to cover the deficit created by the flow regulator 6 with an increased water balance in the building's water supply system.

After reducing the water intake in the building's water supply system below the flow rate specified for regulator 6, it opens and allows water to be drawn for dispensing and the flow required to fill the tank of the accumulator 3. After filling the latter, the plunger closes in the upper part of the water supply valve or the check valve 12 restricts flow on the air pipeline 11.

If there is an unexpectedly large amount of water between which the capacity of the storage tank 3 may be insufficient, the level 10 relay gives a signal and the valve 5 on the pipe 4 is closed, ensuring water flow from the city network without limiting the flow. The same thing can happen if there is a need for fire-fighting in the building. The opening of the valve 5 and the closing of the valve 9 occurs at a signal from the pressure sensor 13 when the water pressure in the common supply pipe 1 rises to a predetermined value.

Since the emptying of the storage tank 3 takes place due to the suction effect of the upgrading pump 2, and the flow controller limits the maximum water flow by increasing the resistance, the application of the proposed system is most appropriate in the water supply systems of buildings connected to With increased water intake, a significant drop in pressure is observed, at which the flow regulator will not throttle a large pressure in the common supply line 1.
