Description

INSTALLING THE INDIVIDUAL

The invention relates to water supply devices and is intended for the water supply of private houses, summer cottages, etc., both from the general non-pressure water supply system, and from open sources - wells, lakes, rivers, as well as containers with imported water.

Water supply of private houses, summer cottages, etc. in places where there is no water supply with sufficient and constant pressure is a rather difficult task, without solving which it is impossible to use, for example, gas water heaters (at a pressure of less than 0.6 ati they do not work), automatic washing and dishwashers and other household appliances requiring a water supply network with guaranteed pressure.

The well-known water supply system of buildings by a. from. USSR 1153020, EOZ B 1/02, 1985, containing a bypass line, a common supply pipe with a pump, a storage tank connected to a common pipe, water folding devices and adjustable valves. To reduce water consumption and electric energy, the system additionally contains a water flow regulator with a throttling device and a level sensor located in the storage tank, connected to valves installed on the pipeline connecting the storage tank to a common line and on the bypass line.

It is also known a device containing pumps, suction and pressure pipes, an air-water tank equipped with liquid level sensors and a safety valve, a compressor or REVERSE

air cooler (Abramov NN, Water supply, Textbook for Universities, 2nd ed., M., Stroyizdat, 1974), as well as another device that differs from the previous one in that the water tank is made with deformable walls and is equipped with a load mounted on the tank with the possibility of vertical movement along the guide racks (AS USSR 632803, ED3 11/02, 1978).

The main disadvantages of the known devices are the high cost and excessive complexity both in manufacturing and in operation, which do not allow their use for individual private houses, summer cottages, etc.

The proposed device - Installation of individual water supply USh-1,5, provides guaranteed water supply to a small private house or summer house with a water pressure in the specified range from 0.6 to 1.5 ati (6 - 15 m water column). The installation contains an air-water tank-accumulator, a suction pipe with a non-return valve, pressure and distribution pipelines, and electrically interconnected manometer and an automatic pump control unit mounted on the battery tank.

Figure 1 schematically shows the proposed device. The UIV-1,5 installation contains an air-water storage tank 1 (a cylindrical steel tank with a capacity of 0.15 cubic meters), an electric pump S (for example, KAMA-10), a check valve 3, installed on the pipeline connecting the pump to the tank, an inlet valve 4 mounted on the suction pipe, an outlet valve 5 mounted on the pressure pipe, as well as an electric manometer 6, which measures the pressure in the agasumulator tank and is electrically connected to the automatic pump control unit 7.

- 2, The installation is connected from the input side (valve 4) to an existing water source and is connected to a 220 V electric network, the installation output (valve 5) is connected to the house’s water supply network. After connecting to the electric network and the water source, the installation is brought into operation by turning on the toggle switch on the automatic control unit 7. The electric pump 2 is turned on and water is pumped into the storage tank 1, while the air in it is compressed as water arrives. The pressure in the tank rises to the level previously set on the electric pressure gauge 6. Recommended upper pressure limit is 1.5 ati, lower - not lower than 0.6 ati (in the absence of such consumers as a geyser, automatic washing machine, etc., installation is possible lower pressure limit to 0.2 ati) As soon as the pressure in the tank reaches the set upper limit of 1.5 ati, unit 7 automatically turns off pump 2 and a pressure from 1.5 to 0.6 ati is provided in the water supply network. When water is consumed, the pressure in the tank gradually decreases and when it reaches the set lower limit of 0.6 ati, unit 7 automatically starts pump 2 and water is again pumped into storage tank 1. A pressure storage tank with a capacity of 0.15 cubic meters provides a supply of water under pressure 0.6 - 1.5 ati between 100 - 120 liters. The frequency of the pump is directly dependent on the degree of water flow. The use of the UIV-1,5 device with water intake from open sources is carried out using a hose with a sampling head equipped with a check valve. The length of the hose should not exceed 15 m, and the depth of water intake is 4-6 meters. - 3
