DRINKING AND FIRE-FIGHTING WATER SUPPLY SYSTEM

The utility model relates to sanitary equipment and can be used as a system of drinking water and fire water for buildings.

A well-known type-building and fire-fighting water supply system of buildings is known, including a supply pipeline, a fire pipeline, household drinking and fire pumps (see, for example, P.A.Spyshnov Designing pipelines in residential and civil buildings, M., 1951).

The technical solution (prototype) closest to the utility model is a drinking water and fire water supply system, including a supply pipe, a fire pipe with fire pumps and household water pumps (see patent No. § JI74044, class A62C37 / 04, 1981).

Significant disadvantages of the known solutions are low operational reliability due to the complexity of the design of the water supply system, as well as the high cost of the system.

The purpose of the utility model is to increase the operational reliability of the system and its efficiency.

The essence of the utility model is that in the drinking water and fire water supply system, including the supply pipe, the fire pipe with fire pumps and the drinking water pump, the fire pipe is combined with the drinking water pipe connected to the supply pipe, and the fire pumps are cold water equipped with adjustable drives controlled

feedback sensors, and used as drinking water pumps, with additional hot water pumps installed on the combined pipeline.

Compared with the prototype (patent Pi No. II74044), the utility model contains new features, namely, that the fire pipeline is combined with the drinking and drinking pipeline connected to the supply pipe, and the cold water fire pumps are equipped with adjustable drives controlled by feedback sensors, and used as household drinking pumps, with additional hot water pumps installed on the combined pipeline.

The utility model is illustrated by the drawing which shows: Fig. 1 is a diagram of a drinking water and fire water supply system with hot water circulation pumps; - figure 2 is the same with the circulation-boosting pumps of hot water.

The drinking water supply and fire water supply system includes a supply pipe I connected to a combined pipe combining the functions of a fire and domestic water supply with cold water through a fire pump 3 and a similar standby pump 4, which are simultaneously boost pumps for cold water supply.

On the combined pipeline 2, additional pumps 5 and b are installed for hot water supply, as well as water heaters, respectively, of the first stage 7 and the second stage 8.

Fire pumps 3 and 4 through adjustable drives 10 and II are connected cashed to its electrical input to the central heat point (accident). (Not shown).

The operation of the adjustable drives 10 and II is controlled by feedback sensors 12 and 13, which monitor the parameters of the water supply system.

A water meter 14 and valves 15 are also installed on the supply line I, and valves 16 on the hot water supply pipelines.

The dashed line shows the electrical connection of adjustable drives and feedback sensors.

And - the distribution point of cold water on the water intake and the water heater of the first stage 7.

The water supply system operates as follows.

At the inlet of the hot water supply network on the supply pipe I and on the combined pipe 2, all valves are open.

Water from the city network through a water meter 14 is fed to the suction of booster pumps 3 and 4 of cold water in a combined pipe 2.

One of the pumps 3 with an adjustable drive 10, due to the presence of a feedback sensor 12, maintains a constant pressure at point A, the value of which is determined by the height of the building.

From point A, water is fed through a combined pipeline 2 to houses and to the first stage of the water heater 7, and then to the water heater of the second stage 8. Hot water is circulated by additional hot water circulation pumps 5 and 6.

It is the presence of a feedback sensor 12 (13) that responds to changes in the parameters of the system and controls through the adjustable drive 10 (11) the performance of the pumps 3 (4), which ensures stable and automatic operation of the system both in normal mode and in the event of a fire.

Due to this, and also due to the absence of any other fire-fighting equipment in the building, requiring the use of manual control, the operational reliability of the system increases and its design scheme is simplified.

In addition, the combination of fire and drinking water pipelines and pumps reduces the cost of the system by at least half.
