SU1291935A1 - Regulator of water level in pools - Google Patents

Abstract

The invention relates to agriculture, in particular to the automatic regulation of water level in rice irrigation systems. The water level regulator in the pools contains a water outlet pipe, a stop valve in the form of a variable volume chamber mounted on the discharge outlet of the water outlet pipe, and a flexible pipe. Switching on and regulating the bell-shaped chamber installed above the water outlet pipe and communicating with the headwater, making the chamber a variable volume elastic, placing it freely in the bell-shaped chamber and communicating it with the air cavity of the bell-shaped chamber allows simplifying the regulator and increasing its reliability. 2 hp f-ly, 3 ill.

Description

The invention relates to agriculture, namely for the automatic regulation of water in rice irrigation systems.

The purpose of the invention is to simplify and increase the reliability of the controller.

Fig. 1 shows the water level regulator and its structure in the closed position, in Fig. 2 the same, in the open position.

that position.

The water level regulator contains a water outlet pipe 1 fixed to plate 2, a bell-shaped chamber 3 installed above the water outlet pipe 1 and communicated by window 4 to the upper reach.

The regulator contains a shut-off element in the form of a variable volume chamber 5, which is made elastic, is installed freely in the bell-shaped chamber 3. In the lower part, the variable volume chamber 5 is equipped with a rigid cup-shaped center 6, in which a hole 7 is made with a stopper 8. The variable volume chamber 5 is communicated with the air cavity of the bell-shaped chamber 3 by means of a tube 9 with a flexible section. The flexible section of tube 9 is fixedly fixed to the half-jKe 10 connected to the lid 11 of the bell-shaped chamber 3, and provided with a locking element made in the form of a sleeve 12 with a plug 13. The sleeve 12 is equipped with a displacement mechanism 14 for pinching the tube 9 with a flexible section. Krshka 11 is made removable and provided with a window 15 which is blocked by a check valve 16.

The water level regulator operates as follows.

In the absence of water in the outlet pipe 1, for example, on rice paddies, a variable volume chamber 5 with a hard center 6 closes the opening of the inlet pipe 1 and is in the lowest position (Fig. 1), window 4, communicated with the upper reach, and window 15 reverse

the valve 16 in the bell-shaped chamber 50 of the process of adjusting the water outlet

pe 3 open, which leads to the filling of the bell-shaped chamber 3 with atmospheric air. As the water level in the upstream reaches, the window 4 of the bell-shaped chamber 3 is submerged under the water, and the air contained in it closes and with a further rise of the water level both in the upstream and in the bell-shaped

at least 3, under pressure of compressed air, the check valve 16 (FIG. 2) closes the window 15. Simultaneously with filling the bell-shaped chamber 3 with water, compressed air enters the cavity of the variable volume chamber 5 through the tube 9 and it floats, water flows through the outlet pipe 1 , maintaining a constant level in the pool (check). With an increase in water filling in the upstream and in the bell-shaped chamber 3, the effect of lifting and buoyancy force, the resultant of which is directed upwards, raises the locking organ upwards, provides a greater discharge of water into the next sprinkler (check). With a decrease in the level of water in the upper reach of the sprinkler in this way, the valve is lowered. The process of moving the variable volume chamber 5 together with the center of the bis sleeve 12 without friction sliding is due to the fact that the valve is seated against the top of the discharge pipe.1 due to the force exiting the water through it to the lower reach. The air contained in the cavity of the variable volume chamber 5 is vented into the bell-shaped chamber. 3, and therefore the buoyant force is reduced, thereby maintaining a constant pressure in the sprinkler 5 automatically. With the change in water in the sprinkler, the process is repeated.

The adjustment of the closure member (chamber 5) can be set (FIG. 3) by turning the mechanism 14 for moving the sleeve 12 in the peg 11 to measure the flow of air into the chamber 5 of a variable volume by pinching the upper end of the tube 9. The tube 9 is in turn also designed to fill water into the variable volume chamber 5 in order to set its weight, the possibility of acceleration and stability

pipe 1, while the opening.6 of the chamber 3 is provided with a stopper 8.
