Description

Technical Field

[0001] This utility model relates to the field of diversion valve technology, specifically a diversion valve structure for water conservancy irrigation. Background Technology

[0002] In water conservancy projects, valves are crucial control devices used to regulate, cut off, or guide water flow. They are widely used in reservoirs, pumping stations, water pipelines, irrigation systems, and drainage facilities, undertaking functions such as flow control, pressure regulation, backflow prevention, and system isolation. Common valve types include gate valves, butterfly valves, ball valves, and check valves. Each type of valve is suitable for different working conditions based on its structure and characteristics. Valve design must consider corrosion resistance, high pressure resistance, and sealing performance to ensure the efficient and safe operation of the water conservancy system. As switches in water conservancy projects, valves play an irreplaceable role in flood control, water supply, power generation, and other fields.

[0003] In existing technologies, different water flow speeds during irrigation result in different irrigation areas. Currently, irrigation typically uses specialized regulating devices to control the flow rate, and multiple water pipes are needed for diversion irrigation. Therefore, strict control of the irrigation flow rate is required to ensure that the irrigation area is fixed, but this requires manual adjustment, which is quite wasteful of manpower. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a water conservancy irrigation diversion valve structure to solve the technical problem that it is labor-intensive to manually use regulating valves to adjust the flow of the diverted irrigation pipes during irrigation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water conservancy irrigation diversion valve structure, including a valve body, two sets of movable plates are movably connected inside the valve body, a pressure-resistant plate is fixedly connected to one side of each movable plate, a connecting plate is fixedly connected to the bottom of each set of movable plates, a connecting rod is fixedly connected to one side of each connecting plate, a flow-limiting plate is movably connected to the end of the connecting rod, and a groove that cooperates with the flow-limiting plate is provided inside the valve body.

[0006] By adopting the above technical solution, this utility model connects the water inlet at the top of the valve body to the water outlet pipe of the water pump with bolts, and places a sealing ring at the connection. The bottom of the valve body has two sets of water outlets, which are also connected to the delivery pipes with bolts and sealing rings. During irrigation, the water pump delivers water into the valve body. The water flow first contacts the pressure plate. The bending design of the pressure plate reduces the water flow speed and mitigates the impact force of the water flow. At the same time, it presses the movable plate to move into the valve body, compressing the spring and driving the connecting plate and connecting rod to move together. The end of the connecting rod is connected to the flow limiting plate. When the water flow is small, the flow limiting plate is in the open state, and the water flow passes smoothly through the valve body. When the water flow is large, the movable plate is fully compressed, pulling the flow limiting plate, making the water outlet in the valve body smaller and reducing the water flow through the valve body. The whole process does not require manual intervention, saving manpower and solving the problem of wasting manpower by manually adjusting the valve flow during irrigation.

[0007] Furthermore, a spring is fixedly connected to one side of the movable plate, and the movable plate is elastically connected to the valve body through the spring. The valve body has a groove inside that matches the movable plate, and the spring is located in the groove inside the valve body.

[0008] By adopting the above technical solution, after the water flows through the valve body, it first presses the movable plate, causing it to move into the valve body, and then squeezes the spring. The flow rate of the water is not constant when it passes through the valve body. Therefore, after the water flows through the pressure plate, it will always maintain a state of motion under the elastic action of the spring. Under the action of the connecting plate and the connecting rod, the flow limiting plate will also continuously open and close, thereby indirectly controlling the flow rate of the water.

[0009] Furthermore, a rotating shaft is movably connected inside the valve body, and the flow-limiting plate is fixedly connected to the rotating shaft.

[0010] By adopting the above technical solution, a groove is provided inside the valve body to cooperate with the rotating shaft, so that the rotating shaft can remain in the valve body without changing its position. This allows the flow limiting plate to open and close inside the valve body with the rotating shaft as the center, ensuring that the flow limiting plate can work according to the water flow rate when the water flow rate is different, thereby effectively controlling the water flow.

[0011] Furthermore, the valve body has an inlet at the top, which is fixedly connected to an external water pump by bolts, and two sets of outlets at the bottom, which are fixedly connected to an external delivery pipeline by bolts.

[0012] By adopting the above technical solution, the water inlet at the top of the valve body is fixedly connected to the water outlet pipe of the external water pump through bolts and flanges, and a waterproof mechanism such as a sealing ring is placed at the connection between the two to ensure that water will not leak to the outside when passing through the valve body. Then, two sets of water outlets are set at the bottom of the valve body and are fixedly connected to the external conveying pipeline through bolts and sealing rings.

[0013] In summary, this utility model has the following beneficial effects: By connecting the water inlet at the top of the valve body to the water outlet pipe of the water pump with bolts and placing a sealing ring at the connection, and providing two sets of water outlets at the bottom of the valve body, which are also connected to the delivery pipes with bolts and sealing rings, during irrigation, the water pump delivers water into the valve body. The water flow first contacts the pressure plate, and the bending design of the pressure plate reduces the water flow speed and mitigates the impact force of the water flow. At the same time, it presses the movable plate to move into the valve body, compressing the spring and driving the connecting plate and connecting rod to move together. The end of the connecting rod is connected to the flow limiting plate. When the water flow is small, the flow limiting plate is in the open state, and the water flow passes smoothly through the valve body. When the water flow is large, the movable plate is fully compressed, pulling the flow limiting plate and reducing the water outlet in the valve body, thus reducing the water flow through the valve body. The entire process does not require manual intervention, saving manpower and solving the problem of wasting manpower by manually adjusting the valve flow during irrigation.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] The embodiments of this utility model will be described below based on its overall structure.

[0021] A water conservancy irrigation diversion valve structure, such as Figure 1-4 As shown, the valve body 1 is made of corrosion-resistant stainless steel and has an anti-corrosion coating on the outside to protect it from rust and other damage caused by the external environment.

[0022] The valve body 1 is internally connected to two sets of movable plates 2. One side of the movable plate 2 is fixedly connected to an anti-pressure plate 3. During irrigation, the water pump first delivers water to the valve body 1, and the water flow first contacts the anti-pressure plate 3. The anti-pressure plate 3 itself is made of austenitic stainless steel and has a curved shape. Therefore, the anti-pressure plate 3 has good corrosion resistance and good elasticity. So after the water flow contacts the anti-pressure plate 3, while pressing the anti-pressure plate 3, the flow velocity of the water flow itself is also reduced, thereby reducing the impact force of the water flow.

[0023] Furthermore, both sets of movable plates 2 are fixedly connected to the bottom of a connecting plate 5, and a connecting rod 6 is fixedly connected to one side of the connecting plate 5. The end of the connecting rod 6 is movably connected to a flow limiting plate 7, and the valve body 1 has a groove inside that cooperates with the flow limiting plate 7. The water flow can press the movable plate 2 through the pressure plate 3, causing the movable plate 2 to move into the valve body 1. The connecting plate 5 on one side of the movable plate 2 will move with the movable plate 2, thereby causing the connecting rod 6 connected to the connecting plate 5 to move together. In turn, the end of the connecting rod 6 is connected to the flow limiting plate 7 and moves together, indirectly controlling the water flow.

[0024] In the example, when the water flow rate is low, the water flow will not excessively compress the movable plate 2. Therefore, under the action of the connecting plate 5 and the connecting plate 6, the flow limiting plate 7 will be in a large open state, so that the water flow can pass smoothly through the valve body 1, ensuring the flow rate of water through the valve body 1. When the water flow rate is high, the water flow will completely compress the movable plate 2. The flow limiting plate 7 can be pulled by the connecting plate 5 and the connecting rod 6, thereby reducing the water outlet inside the valve body 1, reducing the water flow rate inside the valve body 1, and ensuring the water flow rate through the valve body 1 during irrigation.

[0025] In the example, a spring 4 is fixedly connected to one side of the movable plate 2. The movable plate 2 is elastically connected to the valve body 1 through the spring 4. The valve body 1 has a groove inside that matches the movable plate 2, and the spring 4 is located in the groove inside the valve body 1. After the water flows through the valve body 1, it first presses the movable plate 2, causing it to move into the valve body 1, and then squeezes the spring 4. The flow rate of the water is not constant when it flows through the valve body 1. Therefore, after the water flows through the pressure plate 3, it will always maintain a state of motion under the elastic action of the spring 4. Under the action of the connecting plate 5 and the connecting rod 6, the flow limiting plate 7 will also continuously open and close, thereby indirectly controlling the flow rate of the water.

[0026] Furthermore, when no water passes through, the spring 4 resets the movable plate 2, ensuring the operation of the overall mechanism inside the valve body 1, thereby extending the service life of the overall mechanism.

[0027] In the example, a rotating shaft 8 is movably connected inside the valve body 1, and a flow-limiting plate 7 is fixedly connected to the rotating shaft 8. The valve body 1 has a groove inside that mates with the rotating shaft 8, so that the rotating shaft 8 can remain in the valve body 1 without changing its position. This allows the flow-limiting plate 7 to open and close inside the valve body 1 with the rotating shaft 8 as the center. This ensures that the flow-limiting plate 7 can work according to the water flow rate when the water flow rate is different, thereby effectively controlling the water flow.

[0028] In the example, the valve body 1 has an inlet 9 at the top, which is fixedly connected to an external water pump by bolts. The valve body 1 has two sets of outlets 10 at the bottom, which are fixedly connected to an external conveying pipeline by bolts. The inlet 9 at the top of the valve body 1 is fixedly connected to the outlet pipe of the external water pump by bolts and flanges. A waterproof mechanism such as a sealing ring is placed at the connection between the two to ensure that water does not leak to the outside when passing through the valve body 1. The valve body 1 has two sets of outlets 10 at the bottom, which are fixedly connected to the external conveying pipeline by bolts and sealing rings.

[0029] The working principle of this utility model is as follows: When in use, the water inlet 9 at the top of the valve body 1 is first fixedly connected to the water outlet pipe of the external water pump by bolts and flanges, and a waterproof mechanism such as a sealing ring is placed at the connection between the two to ensure that water will not leak to the outside when passing through the valve body 1. Then, two sets of water outlets 10 are set at the bottom of the valve body 1. Similarly, flanges are also set at the water outlets 10, and they are fixedly connected to the external conveying pipe by bolts and sealing rings.

[0030] During irrigation, the water pump delivers water to the valve body 1. The water flow first contacts the pressure plate 3. Since the pressure plate 3 is designed with a curved shape, the flow velocity of the water is reduced after contacting the pressure plate 3, thus mitigating the impact force of the water flow.

[0031] Furthermore, the water flow can press the movable plate 2 through the pressure plate 3, causing the movable plate 2 to move into the valve body 1, thereby squeezing the spring 4. The water flow velocity is not constant when passing through the valve body 1. Therefore, after the water flow impacts the pressure plate 3, it will always maintain a state of motion under the elastic action of the spring 4. Under the action of the connecting plate 5 and the connecting rod 6, the flow limiting plate 7 will also continuously open and close, thereby indirectly controlling the water flow velocity and preventing the water flow velocity from being too fast, which would lead to poor irrigation effect.

[0032] A connecting plate 5 is fixed to one side of the movable plate 2, so that the connecting plate 5 can move together with the movable plate 2, and the connecting rod 6 connected to the connecting plate 5 can move together. The end of the connecting rod 6 is connected to the flow limiting plate 7, so that the water flow can be controlled.

[0033] The valve body 1 has a groove inside that matches the rotating shaft 8, so that the rotating shaft 8 can remain in the valve body 1 without changing its position. This allows the flow limiting plate 7 to open and close inside the valve body 1 with the rotating shaft 8 as the center, ensuring that the flow limiting plate 7 can work according to the water flow rate when the water flow rate is different.

[0034] When the water flow velocity is low, the water flow will not excessively compress the movable plate 2. Therefore, under the action of the connecting plate 5 and the connecting plate 6, the flow limiting plate 7 will be in a large open state, so that the water flow can pass smoothly through the valve body 1 and ensure the flow rate of water through the valve body 1.

[0035] When the water flow velocity is high, the water flow will completely compress the movable plate 2, so that the flow limiting plate 7 can move together with the movable plate 2, making the water outlet inside the valve body 1 smaller, thereby reducing the water flow through the valve body 1, thus achieving the purpose of controlling the water flow. Moreover, the whole process does not require manual intervention, saving manpower and material resources, and ensuring that the water flow is always within a fixed range.

[0036] The above structure can reduce the impact force of water flow while limiting the water flow through valve body 1, thus solving the technical problem that it is labor-intensive to manually adjust the flow of the diverted irrigation pipes using regulating valves during irrigation.
