Description

I

The invention relates to agriculture and can be used to draw water from trough irrigators for irrigation and other needs.

A siphon outlet is known, including a siphon and an additional charge siphon charged through the inlet l.

The disadvantage of this siphon outlet is that in order to re-enable the siphon to work in case of a vacuum, it is necessary to charge the additional siphon and then the worker.

A siphon outlet is also known. It includes a siphon equipped with an air inlet, closed by a tap, and a charging chamber installed on the sifine and communicated with its outlet part fzj,.

However, to activate such a source, it is necessary to repeatedly fill the charging chamber with water,

In order to speed up and simplify the process of switching on, in the proposed siphon charge outlet, the chamber is installed

on the descending branch of the siphon so that the latter passes inside the chamber and is connected with it by the openings, and the upper part of the chamber is located no higher than the crest of the siphon.

The drawing schematically shows the proposed siphon Bodout, section,

along the longitudinal axle.

The outlet consists of a siphon 1, a charging chamber 2, which is installed so that the siphon tube passes inside the chamber, and the charge chamber is located above the output cross-section siphon at a height of not less than the suction height; the upper part of the charging chamber is located not above the crest of the siphon; the chamber has in the lower part a water outlet into the pipe 3 with a tap 4, 8 at the top — an opening B with a tee 6 attached to it. One nozzle of the tee 6 is equipped with a tap 7, and the other is connected to the tee nozzle 9 by means of a tube 8. Tee

9 connected to the air hole

Claims (2)

10 pipes of the siphon in the area of the ridge 11 and provided with a crane 12 mounted on the third nozzle of the tee 9. The bottom of the chamber in the upper part is connected to the siphon pipe through the opening 13. The outlet background tube C has a knee 14. The skfon is installed on the ridge of the tray or irrigator The charge chamber 2 with the valve 4 closed through the pipe of the tee 6 when the valve 7 is open is filled with water. After filling the charge chamber 2, the taps 7 and 12 are closed. To turn the siphon into operation, the edges 4 are opened, the water from the charging chamber 2 is poured into the siphon pipe 1 and fills the knee 14 at the Outlet, which is oriented with the outlet opening upwards. This forms a water barrier, not allowing atmospheric air to enter the siphon cavity during the process of siphon incorporation into the work. With the emptying of the charging chamber 2 in the cavity of the siphon, a vacuum is created that increases with the discharge of the charging chamber. As soon as the vacuum in the siphon cavity reaches a value sufficient to raise the water in the ascending branch of the siphon to the suction height P Opod, this value is understood as the distance from the water level in the sprinkler to the pipe axis on the siphon ridge) water flows through the siphon ridge. When a certain vacuum value is reached, depending on the suction height, the siphon starts to work with a full cross section. After that, the valve 4 is closed, and part of the water enters the pipes of the siphon 1 through the opening 13 into the charging chamber 2. The air of the charging chamber 2 is displaced, the tube is discharged into the siphon pipe through the air outlet 10 and the water flow is removed beyond the siphon. After filling the charge chamber 2, the entire water flow passes through the siphon pipe 1. The siphon is discharged by firing air into its JB through the air jttOHoe hole Yu with an open edge 64 64. If necessary, firing a certain amount of air into the siphon cavity through the air hole 10, it is possible to control the flow of water passing through the siphon pipe. After the siphon in the chamber 2 is turned off, the water level is set at the lower edge of the hole 13. To re-enable the siphon, the tap 12 is closed, the taps 7 and 4 must also be closed, and the tap 4 is opened. The required siphon switch on and off is performed an unlimited number of times. only after the siphon is charged (before it is turned off), chamber 2 is completely filled with water when the tap 4 is closed. o the flow of water supplied to the field. Claims: Siphon outlet, including a siphon equipped with an air inlet, with a stopcock, and a charging chamber installed on the siphon and communicating with the output eixD part, characterized in that, in order to speed up and simplify the Siphon Onset process, the charge chamber is set to the bottom siphon branch so that the latter passes inside the chamber is communicated with it at the entrance by the openings, and the upper part of the chamber is located no higher than the ridge of the siphon.
