[0002] Agricultural valves are key devices used in agricultural production, especially in farmland irrigation systems. They play a vital role in controlling and ensuring the normal operation of irrigation systems, and are crucial in improving the efficiency of farmland irrigation and saving water in agricultural development.
[0003] However, during use, existing irrigation valves are prone to blockage due to sediment deposition in the water flow, which affects the normal opening and closing of the valve and may even cause the valve to jam. This not only affects the efficiency of the irrigation system but also increases maintenance costs. Therefore, those skilled in the art have proposed an agricultural valve to solve the problems mentioned in the background art.
[0004] The information disclosed above in this background section is only intended to enhance the understanding of the background section of this utility model, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides an agricultural valve to address the issue that, in the use of existing irrigation valves, the accumulation of silt in the water flow can easily lead to blockage inside the valve body.

[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. This utility model, by setting an upward-curving guide plate, changes the water flow from laminar to turbulent when water flows through it. By guiding the water flow and changing part of the water flow direction, it flushes the sedimentation area inside the valve, so that the valve can effectively avoid the sedimentation of impurities during irrigation, achieve a self-cleaning effect, prevent the valve body from becoming blocked, affecting the normal opening and closing of the valve, or even causing the valve to jam, thus improving irrigation efficiency.
[0015] 2. This utility model maintains sealing while reducing the contact surface with the internal structure of the valve body through the setting of the valve core.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. It should be noted that the drawings are schematic and not illustrated to scale. For clarity and convenience, the relative sizes and proportions of the parts shown in the drawings have been exaggerated or reduced in size. Any size is only illustrative and not limiting.
[0023] Example:
[0024] Please see Figure 1 - Figure 4 As shown, an agricultural valve includes a valve body 1, with a connection port 11 at one end and a drain port 12 at the other end. A limit tube 13 is provided on the top of the valve body 1, and a spherical protective plate 2 is provided inside the valve body 1. An insertion hole 21 is opened on the top of the spherical protective plate 2, and a rotating component 4 is provided inside the spherical protective plate 2. The valve body 1 serves as the main structure of the valve, supporting other components and providing a water flow channel. The connection port 11 is used to connect to a faucet interface, and an internal thread 111 is provided on the inner side to facilitate a tight fit with the faucet. The connection includes a drain outlet 12 for connecting to a drain pipe and for discharging accumulated water or impurities inside the valve body 1 to keep the inside of the valve body 1 clean. The limiting tube 13 is used to limit the rotation angle of the rotating assembly 4 to prevent damage caused by excessive rotation. The spherical guard plate 2 is located inside the valve body 1 and has openings at both ends. It is fitted with a sealing ring 3 and is connected to the valve body 1 to form a sealing structure. The insertion hole 21 is used to insert the rotating assembly 4. The rotating assembly 4 drives the flow guiding component 44 to rotate inside the spherical guard plate 2 by rotating the handle 42.
[0025] The rotating component 4 includes a rotating shaft 41 rotatably connected in the insertion hole 21. A handle 42 is fixedly connected to the top of the rotating shaft 41, and a protrusion 43 is fixedly connected to the handle 42. A flow guide member 44 is provided at the bottom of the rotating shaft 41. The rotating shaft 41 is used to connect the handle 42 and the flow guide member 44 to transmit rotational power. The handle 42 serves as a user operation component, which drives the rotating shaft 41 to rotate by rotation. The protrusion 43 is limited by the limiting block at the end of the limiting tube 13, which limits the rotation angle of the rotating component 4. The flow guide member 44 is used to realize the flow of water and self-cleaning.
[0026] Specifically, the inner side of the connection port 11 is provided with an internal thread 111, and the end of the limiting tube 13 is provided with a limiting block. The internal thread 111 facilitates a tight connection with the water pipe, and the limiting block is used to limit the rotation angle of the rotating component 4.
[0027] Furthermore, the spherical guard plate 2 has openings at both ends, and sealing rings 3 are snapped into both ends of the spherical guard plate 2. The spherical guard plate 2 is connected to the valve body 1 through the openings.
[0028] Furthermore, the outer diameter of the rotating shaft 41 is adapted to the inner diameter of the insertion hole 21, and the protrusion 43 is provided on the top edge of the limiting tube 13.
[0029] Furthermore, the flow guiding component 44 includes a valve core 441 fixedly connected to the bottom of the rotating shaft 41, a connecting shaft 442 fixedly connected to the bottom of the valve core 441, and a flow guiding plate 443 fixedly connected to the valve core 441. The valve core 441 is used to close or open the valve body 1 channel, the connecting shaft 442 is used to support the flow guiding component 44, and the flow guiding plate 443 has an upward-curved design, which changes the water flow from laminar flow to turbulent flow and avoids the sedimentation of impurities.
[0030] Furthermore, the flow guiding component 44 is disposed inside the spherical guard plate 2, the valve core 441 is attached to the sealing ring 3 on one side, and the connecting shaft 442 is rotatably connected to the bottom of the spherical guard plate 2.
[0031] As can be seen from the above, firstly, the user rotates the handle 42, on which a protrusion 43 is fixedly connected. The protrusion 43 is restricted by the limiting block at the end of the limiting tube 13 to prevent excessive rotation. The rotation of the handle 42 drives the valve core 441, the guide plate 443, and the connecting shaft 442 to rotate in the spherical guard plate 2 through the rotating shaft 41. Secondly, the valve is connected to the water pipe through the connection port 11. The inner side of the connection port 11 is provided with an internal thread 111 to facilitate a tight connection with the water pipe. The water flows into the valve body 1 from the connection port 11 and passes through the guide plate 443 of the guide member 44. The guide plate 443 is designed to be upturned. When the water flows through, the guide plate 443 changes the water flow from laminar flow to turbulent flow. This can prevent impurities from depositing inside the valve body 1 and achieve a self-cleaning effect. Finally, the water flows out through the drain pipe connected to the drain outlet 12 for irrigation.
[0032] By setting up an upward-curved guide plate 443, when water flows through, the guide plate 443 changes the water flow from laminar flow to turbulent flow. By guiding the water flow, the direction of part of the water flow is changed so that it can flush the sedimentation area inside the valve. This allows the valve to effectively avoid the sedimentation of impurities during irrigation, achieve a self-cleaning effect, prevent the valve body 1 from becoming blocked, affecting the normal opening and closing of the valve, or even causing the valve to jam, thus improving irrigation efficiency.
[0033] By setting the valve core 441, the sealing performance is maintained while reducing the contact surface with the internal structure of the valve body 1. In addition, the valve core 441 is reserved at the top and bottom to allow for the valve body 1 to have a large thermal expansion coefficient due to high temperature working environment, so that it can have normal working ability at relatively high temperature. Furthermore, the ball core and ball bag shape design achieves the minimum water storage capacity. By reducing the water storage capacity, the valve is prevented from being damaged by the volume expansion of liquid freezing in extremely cold environment.

The specific connection methods for each part all employ conventional methods such as bolts, rivets, and welding, which are mature technologies in the prior art.
