Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0022] Embodiment 1, as Figs. 1-3 shown:

[0023] A floating ball water control irrigation valve, comprising a diaphragm type floating ball valve body 101, a water box 112 is arranged below the diaphragm type floating ball valve body 101;

[0024] The diaphragm type floating ball valve body 101 is fixedly connected with a three-way pipe 102 at the control chamber position;

[0025] The other two ends of the three-way pipe 102 are fixedly installed with a first guide pipe 103 and a second guide pipe 105, respectively;

[0026] The first guide pipe 103 is installed with a water supply time adjusting valve 104;

[0027] The diaphragm type floating ball valve body 101 is provided with a lever 110, the other end of the lever 110 is provided with a floating plate 111, one end of the lever 110 is hinged to the lower surface of the diaphragm type floating ball valve body 101 through a hinge seat, the other end of the lever 110 is hinged to the upper surface of the floating plate 111 through a hinge seat, the lever 110 corresponds to the pinhole valve 106;

[0028] The second guide pipe 105 is installed with a pinhole valve 106, the other end of the second guide pipe 105 is communicated with the main conveying pipe of the diaphragm type floating ball valve body 101;

[0029] The bottom of one side of the water box 112 is fixedly communicated with a drain pipe 107, and the drain pipe 107 is installed with a drain valve 108;

[0030] The upper surface of the water box 112 is fixedly connected with the diaphragm type floating ball valve body 101 through connecting plates on both sides, and the water box 112 can be made of acrylic plate material, so as to facilitate observation of the water condition in the water box 112.

[0031] In the embodiment, the floating ball water control irrigation valve is realized by using the floating type automatic irrigation, and the diaphragm type floating ball valve body 101 can be connected with a water source main pipe (not shown in the figure) and a spray (drip) irrigation assembly (not shown in the figure) respectively;

[0032] When the main pipe is watered, the water source passes through the diaphragm type floating ball valve body 101 and is delivered to the spray (drip) irrigation assembly, so that the spray (drip) irrigation starts to work;

[0033] The left side of the diaphragm type floating ball valve body 101 is the water inlet end, and the right side is the water outlet end. The water at the water inlet end is conveyed through the main conveying pipeline of the diaphragm type floating ball valve body 101 and discharged through the water outlet end. Part of the water at the water inlet end enters the control chamber of the diaphragm type floating ball valve body 101, is discharged into the three-way pipe 102 through the control chamber, is conveyed into the second conduit 105 and the first conduit 103 through the three-way pipe 102, and the water in the second conduit 105 is conveyed into the main conveying pipeline again and discharged through the water outlet end of the diaphragm type floating ball valve body 101. In this process, the pinhole valve 106 is in a water passing state, and the blockage of the second conduit 105 is removed.

[0034] The first conduit 103 is controlled in displacement through the water supply time adjusting valve 104. By adjusting the water supply time adjusting valve 104, the water flow discharge rate of the first conduit 103 can be adjusted. The water flow of the first conduit 103 adjusted through the water supply time adjusting valve 104 is discharged into the water box 112. When the water in the water box 112 reaches a certain level, the float plate 111 is always floating on the water surface. As the water level continues to rise, the float plate 111 continues to move upwards, thereby driving the lever 110 to fold at an angle, so that the lever 110 is switched from an inclined state to a horizontal state. The lever 110 contacts and presses the pinhole valve 106 on the second conduit 105, drives the pinhole valve 106 to close, and seals the second conduit 105, thereby blocking the water flow. At this time, the water continues to fill the control chamber of the diaphragm type floating ball valve body 101, so that the pressure in the control chamber increases, and the main valve (not shown in the figure) is pushed to close the main conveying pipeline, and the water discharge operation is stopped.

[0035] The water in the water box 112 is evaporated naturally or discharged directly from the drain pipe 107 through the regulating drain valve 108. When the water in the water box 112 is reduced to a certain value, the float plate 111 moves downwards with the water level, thereby driving the lever 110 to separate from the pinhole valve 106. At this time, the sealing of the second conduit 105 is removed, the water pressure in the control chamber of the diaphragm type floating ball valve body 101 is reduced, the main valve is reset, and the water can continue to be discharged and irrigation can be started again.

[0036] The pinhole valve 106 controlled by the lever 110 guides the water flowing out of the second conduit 105 to the water outlet of the diaphragm type floating ball valve body 101, thereby controlling the opening and closing of the diaphragm type floating ball valve body 101.

[0037] The scheme gradually increases the buoyancy by adjusting the size of the water flow rate of the water flow directed out of the first conduit 103 through the water time adjusting valve 104 or the size of the water flow rate (or flow or drop) of the water flow directed out of the water outlet end of the valve through the drain valve 108, when the buoyancy reaches the set value, the opening and closing of the diaphragm type floating ball valve body 101 is realized by triggering the opening and closing of the pinhole valve 106 through the floating plate 111 driving the lever 110, and the water in the water box 112 is dripped out from the drain pipe 107 to reduce the water in the water box 112 to a certain position through the natural evaporation of water and the control of the drain pipe 107 by the drain valve 108, so as to realize the water discharge interval of the diaphragm type floating ball valve body 101, thereby realizing the automatic irrigation of the land for a long time without manual operation, and meeting the actual use requirement.

[0038] It should be noted that the pinhole valve 106 is a pressing type, and the second conduit 105 can be blocked by pressing the pinhole valve 106.

[0039] Meanwhile, the contents not described in detail in the specification all belong to the prior art known to those skilled in the art.
