Abstract

The invention relates to agricultural amelioration and can be used to discharge water into the irrigator with a stabilized flow rate from a closed tubular distributor with a variable flow rate of water. The purpose of the invention is to simplify the design and operation. The water outlet contains a well 2 located between the inlet and outlet sections of the pipeline 1 with inlet, outlet and water outlet connections 3, 4 and 5. In the outlet 4 on the axis 9 there is a butterfly valve 8 connected by a lever 10 and the rod 11 with the float 12. On the lid 13, having an opening 14, a sleeve 15 is fixed with a slot 16. A cable 17 with a handle made in the form of a rod 18 is attached to the upper end of the rod 11. Water from pipe 1 through pipe 3 enters the well 2. The valve 8 supports the well 2 constant water level, discharge the surplus through the pipe 4 in the continuation of the pipeline 1. The pipe 5 for irrigation receives a constant flow of water. To stop the water supply to the pipe 5, the rod 18 is lifted, removed from the slot 16, and turning it 90 ° in plan, is lowered onto the upper flange of the sleeve 15. The valve 8 opens, the water is discharged through the pipe 4 and the water level in the well 2 is lowered below pipe 5. 7 Il.

The invention relates to agricultural land reclamation and can be used to release water into a sprinkler with a stable flow rate from a closed tubular distributor with a variable water flow rate.

The purpose of the invention is to simplify the design and operation.

FIG. 1 shows a water outlet from an underground pipeline, top view; in fig. 2 shows section A-A in FIG. 1 (with fully open throttle valve); in fig. 3 - the same, with the throttle sjaTBOpe closed; in fig. 4 - the same, with the interposition of the throttle valve; ya fig. 5 is a section BB in FIG. one; in fig. 6 is a sectional view BB in FIG. 1 (with the water outlet valve closed); in fig. 7 - the same, with a partially open gate of the discharge pipe.

The outlet from the underground pipeline 1 contains a well 2, an inlet 3 and an outlet 4 nozzles installed in the wall of the well 2 at its bottom, and a water outlet nozzle 5 with a gate 6 located above the outlet nozzle 4. In the well 2, the outlet nozzle 5 removable cover 7 with holes is installed. At the beginning of the outlet nozzle 4, a throttle valve 8 is installed with a central horizontal axis of rotation 9. To the front surface of the shutter 8 when it is closed at a straight angle to its plane, the lever 10 is rigidly attached with a downward slope, the free end of which is pivotally connected to the lower end of the vertical rod 11 passed through the elongated hole in the ceiling 7, and rigidly to the upper part of the rod 11 attached is a float 12 placed in the well 2 above the overlap 7. In the center of the lid 13 of the well 2 a through hole 14 is made, above which is vertically installed and rigidly connected to the upper surface of the lid 13 retaining sleeve 15 flanges and a diametral slot 16 in its upper part. The height of the slot 16 is equal to the distance between the upper and lower extreme positions of the float 12. To the upper end of the rod 11, located above the upper part of the float 12, the lower end of the cable 17 is attached, to its upper end passing through the hole 14 and the sleeve 15, is attached the middle part of the handle, made in the form of a rod 18 and located on the free end of the sleeve 15. The shutter 6 of the nozzle 5 is made in the form of a vertically mounted removable blade, the handle of which has holes 19 for fixing the shutter 6 in various partially open The values correspond to the specified flow rates of water discharged from the well 2. In one of the holes 19 is inserted the pin 20 of the latch 21. At the outlet of the nozzle 5 is placed the initial section of the open sprinkler 22, and the nozzles 3 and 4 are connected

respectively, with the inlet and outlet portions of the pipeline 1.

In the initial position (FIGS. 2 and 6), the rod 18 is located on the upper flange of the sleeve 15, the cable 17 is pulled over the nipple, the rod 11 and the float 12 are in the upper position, the shutter 8 is completely open and all the water of the pipeline 1 passes transitually through the well 2. The bolt 6 pin 20 is fixed in the closed position.

To supply water to the sprinkler 22 with the maximum design water flow rate, the shutter 6 is fully opened (Fig. 5). If it is necessary to supply water to the sprinkler 22 with a lower flow rate, the shutter 6 is opened partly (Fig. 7). After that, the rod 18 is rotated around the vertical axis and smoothly lowered along with the rod 11 and the float 12 suspended to it at the bottom of the slot 16 (Fig. 3). This leads to the complete closure of the shutter 8.

In order for the outlets to work in automatic mode, the maximum flow of water in pipeline 1 must be greater than the estimated discharge flow. If this condition is met, the well 2 is filled with water to the design level, which leads to the rise of the float 12, the partial opening of the butterfly valve 8 and the release of excess water from the well 2 (Fig. 4). The increase in water flow in pipeline 1 leads to an increase in transit water flow through cathode 2, and a decrease in water flow in pipe 1 reduces the water flow in transit through well 2. At the same time, the flow rate of water discharged from the well to the open irrigator 22 does not change. At the end of irrigation, shutter 6 is closed, rod 18 is raised and placed on the upper flange of sleeve 15. This ensures complete opening of shutter 8 and transit passage through well 2 of the entire water flow of pipeline 1. With bilateral water outlet in well 2, a second outlet is installed 5.
