Abstract

This invention relates to the field of automatic control of water supply to multi-reservoir self-flowing agricultural plant. water supply. In order to increase the speed of the system, it contains a pressure tank, tanks located on a slope and connected in series with pipelines. The first tank is connected to the pressure tank by the supply pipe, upper level limiters are installed at the tank inlet, and the first tank limiter is connected to a three-way valve that is installed between the first tank of the first gravity unit and the first tank of the first gravity unit. The inlet of each tank, except the first, is located at the height of the upper level, and the outlet of each tank, except the last, at a height of at least half. these are the heights of the upper level. 2 Il.

Description

one

The invention relates to the field of automatic regulation of water supply in multi-reservoir gravity-flow agricultural water supply installations.

The purpose of the invention is higher system speeds.

FIG. system presented, general view; in fig. 2 - the location of the three-way valve.

The system for regulating the water supply to the multi-reservoir gravity flow units includes a pressure tank 1, tanks 2 located along a slope and in series, connected by pipelines. The first tank 2 is connected to the pressure tank 1 by the feed pipe 3. The inlet nozzles 4 of the tanks 2 have upper limit stops 5, and the stop 5 of the first tank 2 is connected to a three-way valve 6 which is installed between the first nozzle 4 of the first tank 2 and the inlet 7 of the first reservoir of the second gravity installation. The inlet 4 of each tank 2, except the first, is located at the height of the upper level, and the outlet of 8 each tank, except the last, at a height of at least half the height of the upper level.

The system works as follows.

Water from the pressure tank 1 through line 3 enters the first tank 2. When filling the primary tank 2 to the level of the outlet nozzle 8, the water through the pipeline connecting the outlet nozzle In the previous tank 2 with the inlet nozzle 4 of the next tank 2, flows into the next tank 2, located down the slope and also filled with water to the level of the outlet nozzle 8, and so on. When this is the last tank 2, it is always filled to the upper level, since it does not have an outlet.

When filling the last tank 2 to the top level of the gci state, 264192

The upper level plug 5 automatically overlaps the inlet 4, the water supply stops and the filling takes place to the top level-: standing above the slope of tank 2 and so on to the first tank 2, which is filled to the maximum level last.

0 When filling the first tank 2 to the upper level, the upper limiter 5, connected to the three-way valve 6, closes the water supply to the first self- (the 5th installation and the water through the inlet 7 to the second gravity installation).

Such a water supply system to multi-tank self-flowing tank installations allows to accelerate the delivery of water to consumers from all tanks and reduce the cost of building the system. 25
