Description

Technical Field

[0001] This application relates to the field of valve device technology, and in particular to an overflow pressure regulating valve for reducing water pressure fluctuations in irrigation and fertilization pipeline networks. Background Technology

[0002] In modern agricultural fertilization systems, pressure regulating valves are often used to control hydraulic fluctuations.

[0003] Most pressure regulating valves on the market currently use a fixed-stiffness spring structure, which has the problems of fixed pressure regulation and inability to adapt to different irrigation scenarios. Moreover, when the spring or valve core is damaged, the entire valve needs to be replaced, resulting in high maintenance costs and complex operation. At the same time, traditional valves often lack venting or pressure relief functions, which can easily lead to air resistance accumulation and frequent water hammer effects, affecting the service life of the equipment.

[0004] Existing technologies use electronically controlled pressure regulation to adjust the pressure of pressure-regulating valves, but this method has drawbacks such as reliance on electricity, complex structure, and high cost, making it unsuitable for irrigation systems in remote areas. Utility Model Content

[0005] To address or partially address the problems existing in related technologies, this application provides an overflow pressure stabilizing valve for reducing water pressure fluctuations in irrigation and fertilization pipelines. This valve can achieve the purpose of overflow pressure stabilization in pipelines, ensuring stable flow at the pipeline outlet. Moreover, the overall solution does not require electrical control components and is suitable for energy-saving irrigation systems in remote areas.

[0006] This application provides an overflow pressure regulating valve for reducing water pressure fluctuations in irrigation and fertilization pipeline networks, comprising: a valve body, a valve core, an adjusting spring, and a valve cover;

[0007] The valve body has a hollow structure, with an inlet at the bottom and an overflow port on the side wall of the valve core.

[0008] The valve core is placed on a mounting platform inside the valve body. The valve core is closed at the bottom and open at the top, and a pressure boss is provided at the bottom of the valve core.

[0009] The valve core has a first slot inside, and the adjusting spring is installed in the first slot.

[0010] The valve cover is installed on the top of the valve body and is fixed to the valve body by bolts;

[0011] The bottom of the valve cover is provided with a limiting cylinder, and the inside of the limiting cylinder is provided with a second slot. After the valve cover is installed, the outer wall of the limiting cylinder is close to the outer wall of the valve body, and the inner wall of the limiting cylinder is close to the outer wall of the valve core. The limiting cylinder limits the valve core, allowing only axial movement of the valve core. The two ends of the adjusting spring are respectively embedded in the first slot and the second slot, and the adjusting spring increases the axial elastic force of the valve core.

[0012] Optionally, in some embodiments of this application:

[0013] The outer wall of the limiting cylinder is provided with several scale grooves of different heights;

[0014] The valve body has a connecting plate on top with several threaded holes, and the valve cover has several through holes. Bolts and nuts are used to connect the valve cover and the valve body through the through holes and threaded holes, thus fixing the valve cover to the valve body. The installation height of the valve cover can be adjusted by adjusting the installation height of the bolts.

[0015] Optionally, in some embodiments of this application:

[0016] The valve body has a first sealing groove on its top, and a first sealing ring is installed in the first sealing groove.

[0017] Optionally, in some embodiments of this application:

[0018] An overflow groove is provided on the outer wall of the limiting cylinder.

[0019] Optionally, in some embodiments of this application:

[0020] The valve core has a second sealing groove on its outer wall, and a second sealing ring is installed in the second sealing groove.

[0021] The technical solution provided in this application may include the following beneficial effects:

[0022] This application installs a valve core and valve cover within the valve body. A spring within the valve body provides downward pressure to the valve core. When the water pressure in the pipeline exceeds the spring pressure, the spring is compressed, causing the valve core to open and begin overflowing. As water overflows, the pressure inside the pipeline decreases, at which point the valve core closes, achieving overflow pressure stabilization and ensuring a stable flow at the pipeline outlet. Simultaneously, this overflow pressure stabilizing valve can also be used as an air vent valve. When gas is present in the pipe and its pressure exceeds the spring's pre-compression force, air can be released, stabilizing the flow rate while saving on the cost of traditional air vent valves.

[0023] The overflow pressure regulating valve of this application has a simple structure, enabling quick disassembly and assembly, simplifying the maintenance process, facilitating on-site operation, and the overall solution does not require electrical control components, saving energy and making it suitable for energy-saving irrigation systems in remote areas.

[0039] Most pressure regulating valves on the market currently use a fixed-stiffness spring structure, which has the problems of fixed pressure regulation and inability to adapt to different irrigation scenarios. Moreover, when the spring or valve core is damaged, the entire valve needs to be replaced, resulting in high maintenance costs and complex operation. At the same time, traditional valves often lack venting or pressure relief functions, which can easily lead to air resistance accumulation and frequent water hammer effects, affecting the service life of the equipment.

[0040] Existing technologies use electronically controlled pressure regulation to adjust the pressure of pressure-regulating valves, but this method has drawbacks such as reliance on electricity, complex structure, and high cost, making it unsuitable for irrigation systems in remote areas.

[0041] To address the aforementioned issues, this application provides an overflow pressure stabilizing valve for reducing water pressure fluctuations in irrigation and fertilization pipelines.

[0051] See Figure 1-8 An overflow pressure regulating valve for reducing water pressure fluctuations in irrigation and fertilization pipeline networks includes: valve body 1, valve core 2, adjusting spring 3, and valve cover 4.

[0052] The valve body 1 has a hollow structure, with an inlet 101 at the bottom and an overflow port 102 on the side wall of the valve core 2.

[0053] In this embodiment, the inlet 101 of the valve body 1 is connected to a tee pipe installed on the pipeline network, and the overflow port 102 of the valve body 1 is connected to a PVC hose.

[0054] The valve core 2 is placed on the mounting platform 103 inside the valve body 1. The valve core 2 is closed at the bottom and open at the top, and a pressure boss 201 is provided at the bottom of the valve core 2.

[0055] The valve core 2 has a first slot 202 inside, and the adjusting spring 3 is installed in the first slot 202.

[0056] The valve cover 4 is installed on the top of the valve body 1 and is connected and fixed to the valve body 1 by bolts 5.

[0057] The bottom of the valve cover 4 is provided with a limiting cylinder 401. The inside of the limiting cylinder 401 is provided with a second slot 402. After the valve cover 4 is installed, the outer wall of the limiting cylinder 401 is close to the outer wall of the valve body 1, and the inner wall of the limiting cylinder 401 is close to the outer wall of the valve core 2. The limiting cylinder 401 limits the valve core 2, allowing only the valve core 2 to move axially. The two ends of the adjusting spring 3 are respectively embedded in the first slot 202 and the second slot 402. The adjusting spring 3 increases the axial elastic force of the valve core 2.

[0058] In this embodiment, by installing valve core 2 and valve cover 4 in valve body 1, the spring in valve body 1 will provide a downward pressure on valve core 2. When the water pressure in the pipeline on valve core 2 is greater than the spring pressure, the spring is compressed and valve core 2 opens and begins to overflow. As the water in the pipeline overflows, the pressure in the pipeline decreases. At this time, valve core 2 will close as the water pressure in the pipeline decreases, thereby achieving the purpose of overflow and pressure stabilization in the pipeline and ensuring a stable flow at the pipeline outlet.

[0059] Specifically: the outer wall of the limiting cylinder 401 is provided with several scale grooves 404 of different heights;

[0060] The valve body 1 is provided with a connecting plate on the top, and five connecting threaded holes 105 are provided on the connecting plate. The valve cover 4 is provided with five connecting through holes 403. The bolts 5 and nuts 6 pass through the connecting through holes 403 and connect to the connecting threaded holes 105 to realize the connection and fixation between the valve cover 4 and the valve body 1. The installation height of the valve cover 4 can be adjusted by adjusting the installation height of the bolts 5.

[0061] In this embodiment, by adjusting the installation height of the valve cover 4 and adjusting the scale groove 404 on the outer wall of the limiting cylinder 401, the elasticity of the spring inside the valve body 1 can be adjusted, thereby adjusting the pressure of the spring on the valve core 2. The pressure can be selected according to the needs of the irrigation system, thereby realizing the adjustment of different water flow pressures and meeting the diverse needs during irrigation.

[0062] Specifically: a first sealing groove 104 is provided on the top of the valve body 1, and a first sealing ring 7 is installed in the first sealing groove 104. The first sealing groove 104 is made of rubber.

[0063] In this embodiment, by setting a first sealing ring 7, the first sealing ring 7 can fill the assembly gap between the valve body 1 and the valve cover 4 to form a sealing interface, preventing water or fertilizer from leaking from the top of the valve body 1 and ensuring stable system pressure.

[0064] Specifically: An overflow groove 405 is provided on the outer wall of the limiting cylinder 401.

[0065] In this embodiment, by setting an overflow groove 405, the overflow groove 405 can provide a better directional flow channel for water flow. When the valve core 2 moves up to open the overflow, the high-pressure water flow is quickly guided to the overflow port 102 through the overflow groove 405 to avoid overflow blockage.

[0066] Specifically: a second sealing groove 203 is provided on the outer wall of the valve core 2, and a second sealing ring 8 is installed in the second sealing groove 203. The second sealing groove 203 is made of rubber.

[0067] In this embodiment, by setting a second sealing ring 8, the second sealing ring 8 can fill the assembly gap between the valve body 1 and the valve core 2 to ensure that the displacement action of the valve core 2 is driven only by the dynamic balance of water pressure and spring force, and avoid leakage interfering with pressure control.

[0068] The technical solution provided in this application may include the following beneficial effects:

[0069] This application installs a valve core 2 and a valve cover 4 in the valve body 1. The spring in the valve body 1 provides a downward pressure to the valve core 2. When the water pressure in the pipeline on the valve core 2 is greater than the spring pressure, the spring is compressed, and the valve core 2 opens and begins to overflow. As water overflows from the pipeline, the pressure inside the pipeline decreases. At this time, the valve core 2 closes as the water pressure in the pipeline decreases, achieving the purpose of overflow pressure stabilization in the pipeline and ensuring a stable flow at the pipeline outlet. Simultaneously, the overflow pressure stabilizing valve of this application can also be used as an air vent valve. When there is gas in the pipe and the pressure exceeds the pre-compression force of the spring, air can be released, saving the cost of an air vent valve while stabilizing the flow rate.

[0070] The overflow pressure regulating valve of this application has a simple structure, enabling quick disassembly and assembly, simplifying the maintenance process, facilitating on-site operation, and the overall solution does not require electrical control components, saving energy and making it suitable for energy-saving irrigation systems in remote areas.
