The invention with the structure has the following beneficial effects: the invention provides a water-saving irrigation valve based on closed-loop feedback control and a using method thereof, aiming at solving the problems that water resources are wasted and crops are damaged due to excessive irrigation when people need to patrol and careless in the agricultural irrigation process; the invention creatively applies the feedback principle (introduces feedback to improve the process or the action), and feeds back the water level height information to the valve clack closing control device in a way of driving the elastic sheet by the buoyancy of water; the water level height when the trigger valve is closed is adjusted through a water level threshold adjusting device; in order to shorten the distance between the water flow end point and the water flow starting point, the water flow path in the irrigation process is rearranged, a signal remote transmission system is replaced by simple mechanical transmission, and the problem that the irrigation valve needs to use a wireless module to transmit water level information at the end point during feedback is solved; because a certain distance still exists between the water level sensing system and the irrigation valve body, according to the lever principle, the longer the distance between an action point and a fulcrum is, the more labor is saved, but the longer the movement distance is, in order to solve the problem, the invention creatively uses the pre-action principle (necessary change is applied to an object in advance), according to the characteristic that the attraction force between the magnetic steel and the metal sheet is sharply increased along with the shortening of the distance, the attraction force between the magnetic steel and the metal sheet always exists but is smaller than the resistance of the rotation of the long elastic sheet, when the liquid level rises and drives the long elastic sheet to rotate for a certain distance, the rapidly increased magnetic attraction force overcomes the resistance and drives the elastic sheet to continue rotating, so as to drive the valve to close, and the problem that the displacement of the buoy at the water level sensing position cannot be obviously reflected at the valve position is effectively solved;

in the process of practical application, because the magnet is fragile when being impacted and is easy to break when frequently colliding with the metal elastic sheet, in order to solve the problem, the invention creatively uses the principle of pre-reaction (if necessary to carry out actions accompanied with harmful and useful influences at the same time, the pre-reaction is carried out to control the harmful influences), the bottom of the long elastic sheet is provided with a convex blocking magnetic block which can slide in a telescopic way, the characteristic that the interaction force between the magnets is sharply increased along with the reduction of the distance is fully utilized, when the metal elastic sheet and the magnet are in contact, the circular blocking magnetic block generates obvious resistance, and because the volume and the magnetic field strength of the cylindrical adsorption magnetic block are all larger than those of the circular blocking magnetic block, the attraction force between the cylindrical adsorption magnetic block and the metal elastic sheet is always larger than the repulsion force between the circular blocking magnetic block and the cylindrical adsorption magnetic block, however, the distance between the cylindrical adsorption magnetic block and the circular blocking magnetic block is smaller, so that the increasing speed of the repulsive force between the circular blocking magnetic block and the cylindrical adsorption magnetic block is greater than the increasing speed of the adsorptive force between the metal elastic sheet and the cylindrical adsorption magnetic block, the force and the speed of the metal elastic sheet impacting the cylindrical adsorption magnetic block can be reduced through the repulsive force between the cylindrical adsorption magnetic blocks of the circular blocking magnetic block, the effect of protecting the cylindrical adsorption magnetic block is achieved, and the problem that the adsorption magnetic block is prone to being cracked when frequently impacting the metal elastic sheet is effectively solved; because the movement mode of the metal elastic sheet is rotation, and the movement mode of the inclined driving rod is sliding, the contact position of the metal elastic sheet and the inclined driving rod is easy to be discontinuous and the abrasion is fast, the invention creatively provides the semicircular friction pressing block, applies the dimension change principle (different surfaces of a given area) to change surface contact into continuous and smooth line contact, and effectively solves the problems of large resistance and fast abrasion of the friction part of the metal elastic sheet and the inclined driving rod; in order to further optimize the structure, the invention creatively provides the flat plate type half-opening and closing valve flap, and by applying the principle of changing harm into benefit (utilizing harmful factors to obtain beneficial effect), when the valve is opened, the liquid pressure is used as the pressure for keeping the valve flap open, and when the valve is closed, the liquid pressure is used as the driving force for closing the valve and pressing and sealing, thereby effectively solving the problems that the prior energy-saving irrigation valve needs to use radio transmission signals, the float short-distance movement cannot control the valve to close, the magnet is easy to break, and the valve needs to be opened and closed to overcome larger water flow resistance.

when the water is poured after the setting is finished, the water flow starts to flow from the starting position to the end position, when the water level at the end of the water flow reaches the preset height, the low-density buoy 73 receives the buoyancy of the liquid and rises upwards, the buoy mounting lifting platform 72 can only move along the pointed buoy fixing reference rod 67 under the limit of the lifting platform waist-shaped clearance guide hole 79, and the water level threshold adjusting device 66 rotates around the long elastic sheet rotating pin 8 along with the longitudinal buoy adjusting nut 40, so that when the water level at the low-density buoy 73 rises, the water level threshold adjusting device 66 can push the longitudinal buoy adjusting nut 40 upwards, and because the long flat plate type elastic sheet 9 rotates around the long plate type rotating pin 8, the flat plate short side elastic sheet metal pressing plate 36 rotates and falls when the longitudinal buoy adjusting nut 40 rises, attraction always exists between the metal pressing plate 36 with the short side of the flat spring plate and the cylindrical adsorption magnetic block 12, the attraction increases along with the decrease of the distance between the two, when the metal pressing plate 36 with the short side of the flat spring plate is at the initial upper limit position, the elasticity of the pre-tightening reset spring 25 of the inclined slide rod plus the self gravity of the water level threshold adjusting device 66 is larger than the attraction between the cylindrical adsorption magnetic block 12 and the flat spring plate, so that the metal pressing plate 36 with the short side of the flat spring plate and the cylindrical adsorption magnetic block 12 cannot be attracted at the moment, but when the distance between the metal pressing plate 36 with the short side of the flat spring plate and the cylindrical adsorption magnetic block 12 is reduced, the attraction between the metal pressing plate 36 with the short side of the flat spring plate and the cylindrical adsorption magnetic block 12 is rapidly increased, until the force is larger than the resistance of the metal pressing plate 36 with the short side of the flat spring plate to rotate downwards, the metal pressing plate 36 with the short side of the cylindrical adsorption magnetic block 12 is adsorbed to the lower part, in the process that the metal pressing plate 36 on the short side of the flat spring plate rotates downwards, because the volume and the magnetic field intensity of the cylindrical adsorption magnetic block 12 are both larger than those of the circular blocking magnetic block 11, so the attraction force between the cylindrical attracting magnetic block 12 and the metal pressing plate 36 with the short side of the flat spring plate is always greater than the repulsion force between the circular blocking magnetic block 11 and the cylindrical attracting magnetic block 12, but since the distance between the cylindrical attracting magnetic block 12 and the circular blocking magnetic block 11 is smaller, the increasing speed of the repulsive force between the circular blocking magnetic block 11 and the cylindrical attracting magnetic block 12 is greater than the increasing speed of the attracting force between the flat spring short-side metal pressing plate 36 and the cylindrical attracting magnetic block 12, therefore, the force and speed of the metal pressing plate 36 with the short side of the flat spring plate can be reduced when the metal pressing plate 36 impacts the cylindrical adsorption magnetic block 12 through the repulsive force between the cylindrical adsorption magnetic blocks 12 of the circular blocking magnetic block 11, so that the effect of protecting the cylindrical adsorption magnetic block 12 is achieved; after the repulsive force between the circular blocking magnetic block 11 and the cylindrical adsorbing magnetic block 12 is greater than the elastic force of the transverse U-shaped micro elastic sheet 10, the transverse U-shaped micro elastic sheet 10 is compressed, at the moment, the circular blocking magnetic block 11 retracts into the blind hole 41 at the bottom of the elastic sheet, and in the retraction process of the circular blocking magnetic block 11, because the elastic force of the transverse U-shaped micro elastic sheet 10 is increased along with the increase of the deformation quantity, the speed of the reduction of the distance between the circular blocking magnetic block 11 and the cylindrical adsorbing magnetic block 12 is smaller than the speed of the reduction of the distance between the metal pressing plate 36 at the short side of the flat elastic sheet and the metal pressing plate 36 at the short side of the flat elastic sheet until the cylindrical adsorbing magnetic block 12 and the metal pressing plate 36 at the short side of the flat elastic sheet are attached together; in the process of downwards rotating the metal pressing plate 36 at the short side of the flat spring plate, the semicircular pressing block 26 at the end part of the inclined slide rod is pressed downwards at the same time, so that the square inclined slide rod 20 slides downwards along the hollow square inclined sliding table 61 on the side surface of the square valve body, meanwhile, the strip-shaped connecting rod body 24 drives the flat plate type turnover control valve clack 16 to rotate downwards under the guidance of the arc-shaped circular section sliding rod 21 until the flat plate type turnover control valve clack 16 crosses the vertical position, the pressure of water flow drives the flat plate type turnover control valve clack 16 to rotate continuously, and the magnetic metal boss 57 at the end of the round slide rod is separated from the cylindrical adsorption magnet 22 until the flat plate type turnover control valve clack 16 is pressed on the fixed U-shaped sealing retainer ring 17, therefore, the valve is automatically closed, the farmland irrigation is finished, the integral working process is realized, and the step is repeated when the agricultural irrigation machine is used next time.
The actual operation process is simple and easy, the base fixing ground nail 62 is only required to be inserted into soil at the starting point of the water flow to complete the position fixing of the advanced reaction type semi-automatic control valve body 1, and then the reference rod soil breaking pointed cone 74 is inserted into soil at a proper position at the end point of the water flow to complete the position fixing of the adjustable water level sensing system 2; then, the valve clack is rotated to manually rotate the knob 15, the flat plate type turnover control valve clack 16 is reset to the initial position anticlockwise, and the flat plate type turnover control valve clack 16 is opened; then the height of the low-density buoy 73 is adjusted by rotating the rotary adjusting stud 70 through the sliding rotary handle 71; when the water level at the end of the water flow reaches a preset height, the flat plate type turnover control valve flap 16 is automatically closed.
