Description

(54) SIPHON WATER

one

The invention relates to agriculture and can be used to draw water from irrigation irrigation and other needs as a stationary or portable discharge.

A siphon water outlet for irrigation canals is known, comprising a pipe bent with inlet and outlet ends and a charging mechanism made in the form of a hand-held vacuum pump, the outlet end being made in the form of a flexible pipe, overlapped with a lever clip 1.

However, the known siphon outlet does not automatically charge. Manual labor is required for charging and commissioning.

Closest to the proposed technical essence is a device with a siphon for transfusion of liquids and a separate suction device, including a siphon with a charging mechanism in the form of a bellows 2.

A disadvantage of the device is the impossibility of automatically controlling its level of operation in operation.

The purpose of the invention is to ensure the automatic inclusion of the siphon in the work and increase reliability.

The goal is achieved by the fact that the bellows is connected to the incoming branch of the siphon and is provided with a container open at the top which is rigidly connected to it and communicated with the bellows cavity through a non-return valve located in its bottom.

The drawing shows a siphon outflow in cross section along the axis of the siphon with a cross section of the irrigator.

The siphon outlet consists of a siphon 1 of a bent pipe with an inlet 2 and an outlet 3 ends mounted on the irrigator levee 4. The inlet end of the siphon 15 through outlet 5 is connected to a fixed plate 6 mounted on racks 7 resting on the bottom of the irrigator. The plate is connected to the lower part of the bellows 8. To the upper part of the bellows 8 is attached an open-top tank 9. Between the container 9 and the bellows 8 there is a check valve 10. The upper and lower stops 1 1 and 12 are mounted on the racks.

Siphon outlet works as follows.

The container 9 has the ability to move BepTHKHvibHO on the uprights 7. The lower and upper position of the container 9 is limited by the stops 12 and 11.

In the initial position, when the siphon is not charged, the water level in the irrigator 4 should be below the H mark. There is no water in the tank 9 and it can occupy any position between the stops 11 and 12, depending on the water level.

To charge the siphon, it is necessary to raise the water level above the Hg level. In the process of raising the level, capacity 9, having buoyancy, rises upward, stretching the bellows 8 until it stops against the upper stops 11. As the level rises further, the water reaches the level of the upper edge of capacity 9 and begins to overflow over the edge inside the container 9, riocTeneiiiio filling the bottom C1; the background, then the bellows 8 and the input part of the siphon 1. The check valve 10 is in 1, the floor; open under the weight of its own weight and drained water.

The water, having filled the bellows 8, begins after 11 (), capacity 9. Its buoyancy begins to decrease and when compared with the weight of container 9, the container begins to sink, squeezing the splash tube.

(The siphon squeezes, begins to eject water. Under the pressure of the water, the return valve 1 ~ the 10 valve closes and the water starts to n (into the siphon, closes both branches and starts it. The tank is lowered by ii, 4 / i iiic stops. Under the action discharging the flowing water, the check valve 10 opens and the siphon starts to work.

The siphon operation continues until the water level in the irrigator is at the HZ level.

To stop the siphon, it is sufficient to briefly reset the water level in the sprinkler below the Hz mark, i.e. below the upper edge of the tank 9, which hangs on the lower stops. The flow of water into the tank 9 is stopped, and as the siphon continues to work, the water left behind in the tank goes through the siphon and the jet breaks.

By adjusting the position of the stops, it is possible within certain limits to regulate the start of work of the siphon, its shutdown and the range of levels at which the siphon works.

This siphon water outlet design makes it possible to create portable water outlets, makes it possible to automate the remote control of siphon water outlets using a water level in the irrigator itself.

Formula from gain

A siphon outlet, including a siphon with a charging mechanism, made in the form of a bellows valve with a reverse valve, differing in that, in order to ensure automatic activation of the siphon, the bellows is connected to the inlet branch of the siphon and is rigidly fitted open top container connected to the bellows cavity through a check valve located in its bottom.
