Abstract

The invention relates to automation and can be used, in particular, in irrigation systems. The fluid flow switch contains inlet and outlet piping on which the switching element is mounted. The inclusion of two reservoirs in the switch of fluid flow with floats containing filling and drain channels switched by locking bodies, supplying the rocker arm with floats with drafts connected by a lever movably connected to the switching element, allows switching the fluid flow at specified time intervals due to the energy of the moving stream and the stability of the switching period in each cycle. 1 3. p.

The invention relates to irrigation engineering and can be used in many industries and agriculture.

The aim of the invention is to switch the fluid flow at predetermined time intervals and at the expense of the energy of the moving stream, as well as to ensure the stability of the switch in each cycle.

I.

The fluid flow switch contains two reservoirs 1 and 2 with floats 3 and 4 mounted on the arms of the rocker arm 5, which consists of three parts hinged to each other. The tanks 1 and 2 are equipped with bulk 6 and drain 7 channels, switched locking bodies 8 and 9. Through the slots of the lever 10 of the locking organ

.8 and through the grooves of the lever 1t of the locking organ 9 passes ti gi 12 and 13. The upper part of the tg is terminated by stop elements 14 and 15, having grooves through which the rocker arm 5 passes. For turning the levers 10 and 11 of the locking bodies 8 and 9 stop elements 16 and 17, 18 and 19 are installed. The lower part of the t 12 and 13 is pivotally connected to the lever 20 of the toothed sector 21, which is engaged with the gear 22. Valves are perpendicular to one another with gear 22. 24 of the switching element. The axis 23 of the valves 24 is fixed on the partition 25 inside the tee 26 of the exhaust pipes 27. From the leading pipelines 27 are connected to the inlet pipe 28. The inlet channels 6 are connected by an additional pipe 29 to the inlet pipe

: wire 28. On the additional pipe .29. a valve 30 is installed, controlled by a ratchet mechanism, including: a ratchet 31, which is a driving coupling half. The other is aware of the half coupling 32, on the surface of which the ratchet 31 is seated, being engaged with it by the cams 33, ne. Reduces torque with

the nearest furrow As the tank 1 is filled with water, the float 3 begins to rise. With the float 3, the right end part of the rocker arm 5 begins to rise. the right end of the rocker arm 5 with its middle part, the float 3 will idle, corresponding to watering the first section. Having straightened up in one line, the right part of the rocker arm 5 begins to lift the thrust element 14 with t gay .12. The latter rotates the lever 20 together with the toothed sector 21, which rotates the bristle 22 and the valves 24 sitting on the same axis 23 with it. The gear pair is necessary for the valves 24 to quickly turn at a small angle of rotation of the rocker arm 5. Under the action of the rod 12, the valves 24 turn on half, i.e. at 45 °. Further, at an angle greater than 45 ° of the keyboard 34. Lastly, rotating, over-55, the panels 24 begin to turn under the valve gate 30. The ratchet 31 is affected by the flow of water from the lot-fastener to the driven coupling half 32 spring outlet through the supply and nuts 36. Finding from pipeline 28 to tee 26. Sharply

the ratchet 31 is engaged with the dog 37 mounted on the rod 38, which is pivotally connected to the rocker 5. At the other end, the rod 38 ends with an annular sleeve, which is loosely fitted on the driven coupling half 32 and limited by two retaining rings 39. The dog 37 is tucked into ratchet spring 40.

Switch fluid flow works as follows.

From the trough vodovusk through the supply pipe 28, the water passes to the tee 26 and then to the discharge pipe 27 of the first section of the irrigated floor. From the same trough water outlet, water flows by gravity through pipe 29, valve 30, upper shut-off member 8 and enters tank 1, for which upper shut-off member 8 is in the Open position, and for tank 2 is Closed. At the same time, the lower closure member, in contrast, is in the Open position for water to flow out of reservoir 2 and Closed for reservoir 1. It should be noted that the flow area of the lower closure member 9 is greater than the upper closure member 8. This is done in order to lower one float was not an obstacle to raising another float. Consequently, the water from reservoir 2 quickly flows out into

the nearest furrow As the tank 1 is filled with water, the float 3 begins to rise. With the float 3, the right end part of the rocker arm 5 begins to rise. the right end of the rocker arm 5 with its middle part, the float 3 will idle, corresponding to watering the first section. Having straightened up in one line, the right part of the rocker arm 5 begins to lift the thrust element 14 with t gay .12. The latter rotates the lever 20 together with the toothed sector 21, which rotates the bristle 22 and the valves 24 sitting on the same axis 23 with it. The gear pair is necessary for the valves 24 to quickly turn at a small angle of rotation of the rocker arm 5. Under the action of the rod 12, the valves 24 turn on half, i.e. at 45 °. Further, at an angle greater than 45 ° clac-55, the pans 24 begin to turn under 1 action of the water flow going from the chute discharge outlet through the supply pipe 28 to the tee 26. A sharp turn of the valves 24 is accompanied by a sharp rise in thrust 12 and turning at using the stops 16 and 17 of the levers 10 and 11. Thus, the upper closure member 8 is switched from tank 1 to reservoir 2 and lower closure member 9 from reservoir 2 to reservoir 1. Water from the upper closure member 8 will flow into reservoir 2, and from reservoir 1 the water will drain to one of the nearest furrows. Switch Valves 24. It allows you to close the access of water to the first section and direct the flow of water to the second section of the irrigated field. The mode of operation must be chosen in such a way that the switching of the valves 24 would correspond to the flow of water to the koitz fenders in the first or second section. The adjustment of the initial switching time is determined by valve 30.

Rem re-irrigation is shorter than the initial time, since water reaches the end of the moistened furrow faster. To accomplish this task, the following is provided in the fluid flow switch. When lowering the left side of the middle part of the rocker arm 5, the rod 38 is pivotally connected to it. The dog 37, which is mounted on the belt 38 and: spring-loaded with spring 40, turns the ratchet 31, thereby opening the valve 30. In the latter, a spring-cam is provided. new safety clutch. It was introduced in order to limit the axial movement of the valve gate 30 After opening the valve 30, water in a large amount through the upper closure body 8 enters the tank 2, causing the float 4 to rise faster, thereby increasing the cycle time and reducing the water re-supply time first section. The rotation of the ratchet 31 by the pawl 37 and the acceleration of the cycle should correspond to repeated running of the water to the end of the furrow of the first and second section of the irrigated floor. If, due to a small slope, the switch has occurred prematurely, that is, when re-irrigating, the water did not reach the end of the furrow, then the re-cycle adjustment should be made by shifting the rod 38 into one of the holes closer to the center of rotation, in the middle part of the rocker arm 5. Watering ends when the irrigation rate is required will be supplied to both sections.

The water source of the liquid flow switch can be a tray, a hydrant of a closed irrigation pipeline, or a pump station. Discrete irrigation can be carried out using flexible or rigid irrigation pipes, as well as non-explosive siphon tubes, and even in cases where the irrigator distributes the water manually from a temporary irrigation network.
