Description

Technical Field

[0001] This utility model relates to the field of water-saving irrigation technology, and in particular to a press-type flushing valve for mobile drip irrigation pipes. Background Technology

[0002] Mobile drip irrigation is a novel water-saving irrigation technology that combines the advantages of large sprinkler irrigation machines and drip irrigation systems. By modifying the sprinkler heads of large sprinkler irrigation machines into mobile drip irrigation pipes, and using the sprinkler truss to tow the mobile drip irrigation pipes across the ground, large-area automated irrigation can be achieved, while avoiding canopy trapping and evaporation drift losses during sprinkler irrigation. This technology is particularly suitable for the large-scale, intensive production of forage crops such as alfalfa and oats in arid and semi-arid regions, and is key to promoting the green and high-quality development of China's livestock industry. However, the biggest drawback of drip irrigation is its susceptibility to clogging, which severely reduces the system's lifespan. Clogging of mobile drip irrigation pipes is often caused by the deposition of impurities such as calcium, magnesium, and iron salts, microorganisms, and undissolved fertilizers in the irrigation water within the dripper channels. In addition to installing a head filtration system, installing a flushing 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 system's lifespan. During flushing, the end flushing valve opens, and the deposits in the drip irrigation pipe are flushed out along with the irrigation water.

[0003] However, current flushing valves often suffer from problems such as large size, complex structure, difficult operation, and poor anti-clogging effect. Furthermore, during irrigation, they can easily become entangled and drag crop stems as the drip irrigation pipe moves, leading to lodging and reduced yield. Their significant weight also places additional load on the sprinkler truss. Existing flushing valves cannot meet the requirements of mobile drip irrigation systems.

[0004] To address this, a push-button flushing valve for mobile drip irrigation tubing is proposed. Utility Model Content

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0040] 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.

[0041] Reference Figures 1-16 This utility model provides a press-type flushing valve for mobile drip irrigation pipes, including a valve body 1 and a valve core 2;

[0042] The valve body 1 includes a cavity 11 and a Green interface 12; the Green interface 12 is used to connect a mobile drip irrigation tube. The bottom of the cavity 11 is provided with a limiting groove 17, a sealing groove 19 and a first sealing structure 18 from bottom to top. The Green interface 12 is fixedly connected to the top of the cavity 11. A drain outlet 16 is provided at the bottom of the side wall of the cavity 11. A water inlet 14 is provided at the top of the Green interface 12.

[0043] The valve core 2 includes a water-permeable support component, an elastic element, a drain grille 22, a handle 26, and a connecting rod 24. The water-permeable support component is installed on the inner wall of the inlet 14.

The handle 26 is installed at the bottom of the third sealing structure 25, and the handle 26 is located below the cavity 11.

[0044] The drainage grid 22, the connecting rod 24, and the second sealing structure 21 are all located inside the cavity 11. The top of the handle 26 assembly passes through the limiting groove 17 and the sealing groove 19, and is connected to the first sealing structure 18.

[0045] The shape of the second sealing structure 21 is adapted to the shape of the first sealing structure 18, the structure of the third sealing structure 25 is adapted to the structure of the limiting groove 17, a drainage gap is provided between the outer wall of the connecting rod 24 and the sealing groove 19, and the length of the connecting rod 24 is greater than the length of the sealing groove 19.

[0050] Further optimization of the scheme: the permeable support component includes a cross support structure 15 installed on the inner wall of the inlet 14. The cross support structure 15 is located close to the slide groove, and the top of the elastic element abuts against the cross support structure 15.

[0051] In a further optimized design, the elastic element includes a spring 23, which is provided with a drainage grid 22. The top of the spring 23 abuts against the cross support structure 15, and the bottom of the spring 23 abuts against the second sealing structure 21.

[0052] Further optimization of the design: the handle 26 is equipped with reinforcing ribs.

The structure is simple, the shape is smooth and there are no protruding structures, which can prevent the drip irrigation pipe from getting tangled and scraping the crop stems during the movement.

[0055] The valve body 1 and valve core 2 are typically made of durable plastic that is resistant to high and low temperatures and has sufficient mechanical strength and corrosion resistance.

[0056] Further optimization of the scheme: several locking structures 13 are fixedly installed on the outer wall of the Green interface 12. The locking structures 13 are arranged at intervals from top to bottom. A ring-shaped protrusion is fixedly connected to the locking structure 13, and the ring-shaped protrusion abuts against the inner wall of the moving drip irrigation tube. The size of the locking structure 13 matches the inner wall of the 16mm moving drip irrigation tube, so that it can be firmly connected after the drip irrigation tube is inserted to prevent water leakage.

[0057] The design has been further optimized by installing a support structure inside the drain outlet 16. This support structure can increase structural strength while preventing deformation, and improve the service life of the flushing valve.
