Abstract

Use: in agriculture when irrigation with sprinkling, provides an increase in the radius of action. The locking body 3 of the hydropneumoaccumulator 1 is provided with a housing 5 with a travel stop 6 and trunks 7. The housing 5 is installed coaxially with the throat 2 and a locking organ is placed in it in the form of a differential valve 3. When water is pumped into the hydro-pneumatic accumulator 1 after filling it together with the housing 5 and the shafts 7 is lifted above the differential valve 3. A surge of water from the hydroaccumulator 1 to the atmosphere through the barrels 7 occurs. After the hydraulic accumulator 1 is emptied, the pressure in it drops and it drops to the differential valve 3. ie the water is stopped. 3 il. 8 4 WITH 00 With Figure 1

Description

The invention relates to agriculture, in particular, to engineering, and can be used for irrigation by sprinkling.

The purpose of the invention is to increase the spray distance.

FIG. 1 shows a diagram of a pulse sprinkler, section; 2 is the same during the filling period; in fig. 3 - the same during the splash period.

The device consists of a hydropneumatic accumulator 1 with a throat 2 in the lower part, the output section of which is the seat of the differential valve 3, mounted vertically on a fixed rack 4. Coaxially with the throat 2 to the hydropneumatic accumulator 1, the valve chamber 5 is fixed with a travel stop in lower part. In the upper part of chamber 5, trunks 7 with nozzles 8 are installed. The nozzle axes do not intersect with the vertical axis of the neck 2 and chamber 5. The feed pipe 9 is connected to the hydro-pneumatic accumulator 1 through a channel in a fixed rack 4 and a differential valve 3.

The device works as follows.

In the non-working state, under the action of the force G of the hydropneumoaccumulator 1 with water, its throat 2 is pressed by the output section with the saddle to the differential valve 3, the valve is closed. When water is pumped through the feed line 9 into the hydropneumoaccumulator 1, its weight G increases, and the pressure in it increases simultaneously, as well as the weighting force of the hydrostatic pressure

on the surface of the projection of the valve seat on the surface of the hydropneumoaccumulator 1, directed upwards PJ.

At a certain degree of filling with water, the hydropneumatic accumulator of the weighing force P exceeds the weight force G and the hydropneumatic accumulator 1, together with the valve chamber 5 and the shafts 7, rises above the differential valve 3. The pressure in the valve chamber 5 spreads over the entire area of the valve 3. The weighing force of the hydrostatic pressure acting on the projected area of the entire surface of the differential valve 3, on the surface of the hydro-pneumatic accumulator 1, increases upward, the device moves up to the stop of the limit 6 Ithel stroke in the differential valve 3. The valve seat is opened, gidropnevmoakkumul Torr communicates with the atmosphere. The displacement of water from the hydro-pneumatic accumulator 1 by compressed air begins and its outflow through the trunks 7 and the nozzle 8 in the form of a sprinkling jet is a splash.
