[0021] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0022] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, this embodiment provides an agricultural water-saving automatic irrigation PE valve, including a PE main valve body 1 and a PE auxiliary valve body 2 that are interconnected and butted, both of which are made of PE material, wherein the PE main valve body 1 is located at the top of the PE auxiliary valve body 2, a water inlet pipe 3 for introducing irrigation water is fixed to the right side wall of the PE main valve body 1, a drain pipe 4 for discharging irrigation water is fixed to the left side wall of the PE auxiliary valve body 2, a flange ring 5 is sealed and butted at the right end of the water inlet pipe 3, and the water inlet pipe 3 is sealed and butted with the water outlet of the water source through the flange ring 5, a threaded ring 6 is welded and fixed on the left side of the flange ring 5, an external thread is provided on the outer wall of the threaded ring 6, and an internal thread matching the external thread is provided on the right side inner wall of the water inlet pipe 3, a motor 7 is fixed on the inner side of the threaded ring 6, and symmetrically distributed crushing blades 8 are fixed on the output end rotating shaft of the motor 7, and the large volume impurities entering the water inlet pipe 3 are crushed by starting the motor 7 inside the threaded ring 6 to drive the crushing blades 8 fixed at its output end to rotate, thereby avoiding large volume impurities in the water source. Impurities cause blockage to the valve body, ensuring the normal use of the valve body. A servo motor 9 is fixed to the left outer wall of the PE main valve body 1 by screws. A water blocking plug 10 adapted to the water inlet pipe 3 is arranged inside the PE main valve body 1, and the water blocking plug 10 is driven to move by the servo motor 9. The PE main valve body 1 and the PE auxiliary valve body 2 are interconnected and sealed at one end. The PE main valve body 1 and the PE auxiliary valve body 2 are provided with openings that are interconnected at one end. A threaded sleeve 11 is provided on the upper sliding sleeve of the outer wall of the PE auxiliary valve body 2. The upper part of the threaded sleeve 11 is threadedly sleeved on the lower part of the outer wall of the PE main valve body 1. The lower part of the outer wall of the PE main valve body 1 is provided with an external thread adapted to the internal thread of the threaded sleeve 11. A threaded sleeve 11 that can be threadedly screwed on the outside of the PE main valve body 1 is slidably sleeved on the outside of the PE auxiliary valve body 2, so that the PE auxiliary valve body 2 and the PE main valve body 1 can be conveniently disassembled and assembled. A mounting seat 12 is welded and fixed at the bottom end of the PE auxiliary valve body 2.

[0023] A soil humidity sensor 13 for detecting the soil humidity value of farmland is fixed to the bottom of the mounting seat 12 by screws, and an air humidity sensor 14 for detecting the air humidity value of farmland is fixed to the top of the PE main valve body 1 by screws. The soil humidity sensor 13 and the air humidity sensor 14 are both connected to the PLC control system of the valve. When the humidity value detected is not up to standard, the servo motor 9 is started to drive the water blocking plug 10 to move and open the water inlet pipe 3. When it is detected that the humidity value is up to standard, the servo motor 9 is started to drive the water blocking plug 10 to move in the opposite direction and close the water inlet pipe 3, so as to realize the automatic opening and closing of the valve and play a role in water saving.

[0024] A support frame 15 is fixed to the left inner wall of the PE main valve body 1, and the servo motor 9 penetrates into the support frame 15 through a sealed bearing and is fixed with a screw rod 16, and a threaded plate 17 located in the support frame 15 is threadedly sleeved on the screw rod 16, and a sliding rod 18 that slides through the support frame 15 is symmetrically fixed on one side of the threaded plate 17 close to the water blocking plug 10, and the end of the sliding rod 18 away from the threaded plate 17 is fixedly connected to the water blocking plug 10, and the screw rod 16 is driven to rotate by the servo motor 9 to displace the threaded plate 17 threadedly sleeved on the screw rod 16, thereby driving the sliding rod 18 to displace together with the water blocking plug 10.

[0025] A rubber sealing convex ring 19 is fixed to one end of the water inlet pipe 3 located in the PE main valve body 1, and a rubber sealing groove 20 adapted to the rubber sealing convex ring 19 is fixed to the side of the water blocking plug 10 close to the water inlet pipe 3. When the water blocking plug 10 closes the water inlet pipe 3, the rubber sealing convex ring 19 is inserted into the rubber sealing groove 20 to improve the sealing between the water blocking plug 10 and the water inlet pipe 3.

[0026] The outer wall of the motor 7 is fixedly connected to the inner wall of the threaded ring 6 through symmetrically distributed support rods 21. First annular grooves 22 are provided on opposite sides of the water inlet pipe 3 and the flange ring 5. A first sealing ring 23 is provided between the two groups of first annular grooves 22. The sealing connection between the flange ring 5 and the water inlet pipe 3 is achieved through the cooperation of the first annular grooves 22 and the first sealing ring 23.

[0027] A second annular groove 24 is formed at the top of the PE auxiliary valve body 2, and a second sealing ring 25 adapted to the second annular groove 24 is fixed at the bottom of the PE main valve body 1. The cooperation between the second annular groove 24 and the second sealing ring 25 realizes the sealed docking of the PE main valve body 1 and the PE auxiliary valve body 2.

[0028] A limit stop ring 26 is fixed to the upper part of the outer wall of the PE auxiliary valve body 2, and a limit groove 27 adapted to the limit stop ring 26 is opened at the lower part of the inner wall of the threaded sleeve 11. The limit stop ring 26 extends into the limit groove 27 to prevent the threaded sleeve 11 from falling off the PE auxiliary valve body 2, and at the same time plays a limiting role, which can drive the PE auxiliary valve body 2 and the PE main valve body 1 to be closely connected.

[0029] When the agricultural water-saving automatic irrigation PE valve is actually used, the water inlet pipe 3 is connected to the water outlet of the agricultural irrigation water source through the flange ring 5, and the water pump at the agricultural irrigation water source is used to inject water from the water inlet pipe 3 into the PE main valve body 1. At the same time, the motor 7 inside the threaded ring 6 is started to drive the crushing blade 8 to rotate, so that the crushing blade 8 can crush the impurities in the water to avoid the impurities being too large and causing blockage to the PE main valve body 1 and the PE auxiliary valve body 2. Then the water flows from the PE main valve body 1 to the PE auxiliary valve body 2, and finally discharged from the drain pipe 4 to the farmland to achieve agricultural irrigation. When it is necessary to stop irrigation, the servo motor 9 is started to drive the water blocking plug 10 to move to the water inlet pipe 3 and seal it, that is, the PE valve is closed to stop irrigation;

[0030] In order to realize automatic irrigation for agricultural water conservation, the soil humidity sensor 13 and the air humidity sensor 14 are used to detect the soil humidity value and the air humidity value of the farmland respectively. When the humidity value is detected to be below the standard, it means that the farmland environment is relatively dry and irrigation is required, that is, an electrical signal is sent to the servo motor 9 to drive the water blocking plug 10 away from the water inlet pipe 3 and release the seal, so that the farmland irrigation can continue;

[0031] When it is necessary to disassemble and separate the PE main valve body 1 and the PE auxiliary valve body 2, the threaded sleeve 11 can be unscrewed from the PE main valve body 1 to release the docking fixation between the PE main valve body 1 and the PE auxiliary valve body 2. When installation is required, the PE main valve body 1 is first docked and installed on the top of the PE auxiliary valve body 2, and then the threaded sleeve 11 on the outside of the PE auxiliary valve body 2 is screwed upward to the outside of the PE main valve body 1 until the PE main valve body 1 and the PE auxiliary valve body 2 are pressed against each other, and the installation work is completed.

[0032] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
