Description

Technical Field

[0001] The utility model relates to the technical field of water-saving irrigation, in particular to an anti-clogging flushing valve for a mobile drip irrigation pipe. Background Art

[0002] Mobile drip irrigation is a new water-saving irrigation technology that combines the advantages of large-scale sprinklers with drip irrigation systems. By converting the nozzles of large sprinklers into mobile drip irrigation pipes, which are then dragged across the surface using the sprinkler trusses, large-scale automated irrigation can be achieved while avoiding canopy interception and evaporative drift losses during the irrigation process. The biggest drawback of drip irrigation technology is its susceptibility to clogging, which can seriously reduce the lifespan of the irrigation system. Clogs in mobile drip irrigation pipes are often caused by impurities such as calcium, magnesium, and iron salts, microorganisms, and undissolved fertilizer in the irrigation water, which settle within the dripper flow path. In addition to installing a head filtration system, installing a flush valve at the end of the mobile drip irrigation pipe for regular flushing is an effective solution to reduce the risk of dripper clogging and extend the lifespan of the system.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0033] Reference Figure 1-Figure 7 The utility model provides an anti-clogging flush valve for a mobile drip irrigation pipe, comprising:

[0034] The valve body 1 includes a cavity 11 and a Green interface 12. A drain port 15 is provided on one side of the cavity 11, and a water inlet 14 is provided at the bottom of the Green interface 12. The Green interface 12 is fixedly installed at the bottom of the cavity 11 and is used to connect a mobile drip irrigation pipe.

[0035] A first connecting structure 16 , which is installed on the top of the cavity 11 ;

[0036] The valve core 2 includes a handle 24, a second connecting structure 21, and a sleeve 23 fixedly connected from top to bottom; the second connecting structure 21 is engaged with the first connecting structure 16, and the sleeve 23 extends into the inner cavity of the cavity 11 and is rotatably connected to the inner wall of the cavity 11; drainage grooves 27 are formed on the opposite side walls of the sleeve 23, and second sealing structures 28 are installed on the opposite side walls of the sleeve 23, and the drainage grooves 27 and the second sealing structures 28 are arranged alternately;

[0037] A first sealing structure 22 , the first sealing structure 22 being a gasket between the outer wall of the sleeve 23 and the inner wall of the cavity 11 ;

[0038] The two drainage grooves 27 and the two second sealing structures 28 are arranged corresponding to the drainage port 15, and are located at the same height as the drainage port 15. The water inlet 14 and the drainage port 15 are both connected to the cavity 11; the width of the drainage groove 27 is consistent with the drainage port 15 in the valve body 1;

[0039] In this embodiment, the radial width of the valve body 1 and the valve core 2 after assembly is 34 mm, and the axial length is 82 cm. The appearance is smooth and has no protruding structure, which can prevent the drip irrigation pipe from being entangled and scraped down the crop stems during movement.

[0040] In this embodiment, the valve body 1 and the valve core 2 are made of plastic, which is resistant to high and low temperatures and has sufficient mechanical strength. It does not contain metal parts and has strong corrosion resistance.

[0041] With such a configuration, the present invention can connect the drain groove 27 with the drain port 15 by rotating the handle 24, thereby opening the drain port 15. Irrigation water in the mobile drip irrigation pipe enters the flush valve cavity 11 through the water inlet 14 and is discharged from the drain port 15 through the drain groove 27 in the sleeve 23, thereby achieving flushing and preventing the mobile drip irrigation pipe emitter from being clogged. By rotating the handle 24, the second sealing structure 28 can also be aligned with the drain port 15, sealing the drain port 15 and closing the flush valve. At this time, the irrigation water in the mobile drip irrigation pipe slowly flows out from the emitter, thereby achieving drip irrigation.

[0042] The utility model can improve the sealing performance of the flush valve through the first sealing structure 22, so that the flush valve is not prone to water leakage; the utility model has a simple structure, is reliable and durable, and is easy to operate. The overall structure of the flush valve is simple, and the cavity 11 and the valve core 2 are tightly assembled, making the appearance round and without sharp corners, so that crop stems are not easily entangled during irrigation, and can effectively prevent and solve the blockage problem of the mobile drip irrigation system.

[0043] In a further optimized solution, the first connecting structure 16 includes a connecting ring mounted on the top of the cavity 11, and two arc-shaped limiting grooves are provided on the top of the inner side wall of the connecting ring. A locking buckle is installed at the bottom of the second connecting structure 21, and the locking buckle is engaged with the connecting ring. Two sliders are installed on the second connecting structure 21, and the two sliders are respectively slidably connected to the two arc-shaped limiting grooves;

[0044] The second connecting structure 21 is clamped to the connecting ring at the top of the cavity 11 through a locking buckle, and the two sliders are slidingly connected to the two arc-shaped limit grooves respectively, thereby allowing the valve core 2 and the valve body 1 to rotate freely circumferentially around the central axis, but limiting them axially to avoid separation of the valve core 2 and the valve body 1 during use.

[0045] Further optimizing the solution, a plurality of locking structures 13 are fixedly installed on the outer wall of the Green interface 12, and the plurality of locking structures 13 are arranged at intervals from top to bottom. An annular protrusion is fixedly connected to the locking structure 13, and the annular protrusion abuts against the inner wall of the mobile drip irrigation pipe;

[0046] The size of the locking structure 13 matches the inner wall of the 16mm mobile drip irrigation pipe, and can be firmly connected after the drip irrigation pipe is tightly inserted to prevent water leakage.

[0047] According to a further optimized solution, the first sealing structure 22 includes a first groove 25 and a first sealing ring 26. The first groove 25 is formed on the outer wall of the sleeve 23. The first sealing ring 26 is installed in the first groove 25. The first sealing ring 26 abuts against the inner wall of the cavity 11.

[0048] The first sealing ring 26 plays a sealing role after the valve core 2 is installed in the valve body 1 to prevent the irrigation water from flowing out from the gap between the valve body 1 and the valve core 2.

[0049] To further optimize the solution, the second sealing structure 28 includes a second groove 29 and a second sealing ring 210 installed in the second groove 29. The two second grooves 29 are opened on the two opposite side walls of the sleeve 23. The two second grooves 29 and the two drain grooves 27 are arranged alternately. The second sealing ring 210 is set corresponding to the drain outlet 15; the second sealing ring 210 is used to ensure sealing when the sleeve 23 blocks the drain outlet 15 after closing the flush valve.

[0050] To further optimize the solution, a support structure is installed in the drain outlet 15. The support structure can increase the structural strength while preventing deformation, thereby increasing the service life of the flush valve.

[0051] To further optimize the solution, the central angle of the arc-shaped limit groove is 90°, allowing the valve core 2 to rotate within the range of 0-90 degrees to realize the opening and closing of the flush valve. When the flush valve is closed, the second sealing structure 28 of the sleeve 23 can completely block the drain outlet 15. At this time, the second sealing ring 210 of the second sealing structure 28 can ensure that there is no water leakage when the flush valve is closed; when the flush valve is opened, the drain groove 27 is aligned with the drain outlet 15, so that the irrigation water in the mobile drip irrigation pipe is discharged to achieve flushing.

[0052] A further optimized solution is that the handle 24 is an arc-shaped handle with reinforcing ribs installed on it. The handle 24 has a simple structure, a smooth appearance and no sharp corners, which can prevent the drip irrigation pipe from being entangled and scraping down the crop stems during movement. At the same time, it has reinforcing ribs to ensure structural strength and durability.
