Abstract
Description
Technical Field
[0001] This utility model belongs to the field of irrigation solenoid valve technology, specifically, it relates to an intelligent irrigation solenoid valve with adjustable flow rate. Background Technology
[0002] In modern agricultural irrigation systems, solenoid valves, as core components controlling water flow, directly affect irrigation efficiency and agricultural production benefits due to their operational stability. Currently, agricultural irrigation water sources are mostly drawn from natural water bodies such as rivers, reservoirs, and groundwater, or reclaimed water. These water bodies generally contain impurities such as silt, aquatic plants, plankton remains, and organic debris. Furthermore, when water pipelines age or the water source environment changes, foreign matter such as rust and gravel particles may also be introduced.
[0003] When unfiltered irrigation water flows directly through the solenoid valve, small impurities can easily accumulate on the valve disc sealing surface, the inner wall of the valve cavity, or the throttling orifice. This can cause the solenoid valve to not close properly, resulting in water leakage, or the valve core to become stuck and unable to open normally. In severe cases, it can cause the solenoid valve to fail completely. Larger foreign objects can not only scratch the surface of the precision components inside the solenoid valve and damage the sealing structure, but also accelerate the wear of the internal components under the impact of water flow, significantly shortening the service life of the solenoid valve.
[0004] Existing agricultural irrigation solenoid valves are typically designed with fluid control functions in mind, lacking integrated filtration devices. While some systems use independent external filtration equipment, these suffer from problems such as poor compatibility between filtration accuracy and solenoid valves, large installation space requirements, high maintenance costs, and unstable filtration performance.
[0005] In addition, traditional solenoid valves that lack filtration functions require frequent maintenance and replacement in environments with impurities, which not only increases the labor and material costs of agricultural production, but may also lead to crop yield reduction due to water shortage caused by irrigation interruption. Therefore, an intelligent irrigation solenoid valve with adjustable flow rate is proposed. Utility Model Content
[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an intelligent irrigation solenoid valve with adjustable flow that can overcome or at least partially solve the above problems.
[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: an intelligent irrigation solenoid valve with adjustable flow rate, including a solenoid valve with an inlet pipe and an outlet pipe, and further including: a slot, which is formed on the outer periphery of the inlet pipe and connected to the inlet pipe; a filter ring, which is radially inserted into the inlet pipe through the slot and forms an interference fit with the inner wall of the slot; and a clamp, which is sleeved on the outside of the inlet pipe to form a ring clamping force on the filter ring.
[0008] Preferably, the filter ring includes an outer ring and a filter screen fixedly connected to the outer ring, and a sealing plug is fixedly connected to the outer ring for sealing the slot.
[0009] Furthermore, a recessed cavity is formed between the filter screen and the inner diameter of the outer ring, and the recessed cavity faces the water inlet direction.
[0010] Furthermore, sealing rings are provided on both sides of the outer ring.
[0011] Furthermore, the water inlet pipe at the slot has an inner groove, and the outer ring is located in the inner groove.
[0012] Preferably, the clamp includes a first clamping ring and a second clamping ring, which are rotatably connected to the outer wall of the water inlet pipe fitting. A screw is rotatably connected to the first clamping ring, and a nut is threaded onto the screw. A groove is provided on the second clamping ring.
[0013] Furthermore, the inner walls of the first and second retaining rings are provided with clamping grooves, which correspond to the outer ring.
[0014] Furthermore, sealing gaskets are symmetrically fixedly connected to the inner wall of the pressing groove.
[0015] Furthermore, a water pressure sensor is installed on the water inlet pipe.
[0016] Furthermore, an overflow valve is installed on the water inlet pipe.
[0017] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:
[0018] 1. This adjustable flow intelligent irrigation solenoid valve effectively intercepts impurities such as silt, aquatic plants, and planktonic debris in the irrigation water through its filter screen, preventing these impurities from entering the solenoid valve. The cavity formed between the filter screen and the inner diameter of the outer ring faces the water inlet, making it easier for impurities to settle in the cavity under the action of water flow. This reduces the accumulation of impurities on the filter screen, improves filtration efficiency, and prevents impurities from clogging the inside of the solenoid valve.
[0019] 2. This intelligent irrigation solenoid valve with adjustable flow rate prevents larger foreign objects from entering the solenoid valve by intercepting impurities through the filter ring. This prevents foreign objects from scratching the surface of the precision components inside the solenoid valve, damaging the sealing structure, or aggravating the wear of the internal components, thus extending the service life of the solenoid valve.
[0020] 3. The adjustable flow intelligent irrigation solenoid valve uses a radial insertion method to install the filter ring in the slot of the inlet pipe fitting and fix it with a clamp. It is convenient and quick to disassemble and install, and the clamp is designed on the inlet pipe fitting, so there is no need to worry about the clamp being lost.
[0021] 4. This adjustable flow intelligent irrigation solenoid valve features a filter ring that effectively intercepts impurities, protecting internal components and reducing the valve's failure rate and frequency of maintenance and replacement. This reduces labor and material costs in agricultural production and prevents crop yield reduction due to water shortages caused by irrigation interruptions. It effectively solves the problem of frequent maintenance and replacement of traditional solenoid valves in environments with impurities. Through a reasonable structural design, the filtration function is integrated with the solenoid valve, offering advantages such as good filtration effect, convenient maintenance, space saving, and low cost, thus improving the reliability and economy of agricultural irrigation systems.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0035] Example 1: Refer to Figures 1-9 An adjustable flow rate intelligent irrigation solenoid valve includes a solenoid valve 1 with an inlet pipe 11 and an outlet pipe 12, and further includes: a slot 13, which is formed on the outer peripheral wall of the inlet pipe 11 and extends radially, and is connected to the inlet pipe 11; a filter ring 15, which is radially inserted into the inlet pipe 11 through the slot 13 and forms an interference fit with the inner wall of the slot 13; and a clamp 16, which is sleeved on the outside of the inlet pipe 11 to form an annular clamping force on the filter ring 15.
[0036] The filter ring 15 includes an outer ring 151 and a filter screen 152 fixedly connected to the outer ring 151. A sealing plug 153 is fixedly connected to the outer ring 151 to seal the slot 13. A lifting ring 154 is fixedly connected to the outer ring 151 to facilitate quick and easy removal of the filter ring 15.
[0037] A recessed cavity 156 is formed between the filter screen 152 and the inner diameter of the outer ring 151. The recessed cavity 156 faces the water inlet direction. The design of the recessed cavity 156 can be used to collect filtered impurities, which facilitates the deposition of impurities and prevents impurities from flowing into the solenoid valve 1 when the filter ring 15 is pulled out.
[0038] Sealing rings 155 are provided on both sides of the outer ring 151 to improve sealing and prevent water leakage.
[0039] The water inlet pipe 11 located at slot 13 has an inner groove ring 14 on its inner diameter, and the outer ring 151 is located in the inner groove ring 14. When water impacts the filter screen 152, it applies a pushing force to the filter ring 15. Since the outer ring 151 is located in the inner groove ring 14, the inner wall of the inner groove ring 14 provides support for the filter ring 15, effectively preventing the outer ring 151 from deforming due to water impact.
[0040] The clamp 16 includes a first clamp 161 and a second clamp 162. The first clamp 161 and the second clamp 162 are rotatably connected to the outer wall of the water inlet pipe fitting 11. A screw 163 is rotatably connected to the first clamp 161, and a nut 164 is threaded onto the screw 163. A groove 168 is provided on the second clamp 162.
[0041] The inner walls of the retaining ring 161 and retaining ring 162 are provided with pressing grooves 167, which correspond to the outer ring 151.
[0042] A sealing gasket 165 is symmetrically fixedly connected to the inner wall of the compression groove 167.
[0043] When installing the filter ring 15, the outer ring 151 of the filter ring 15 is aligned with the slot 13 and inserted radially into the water inlet pipe 11, so that the outer ring 151 is fully embedded in the inner groove 14 of the inner diameter of the water inlet pipe 11. At this time, the sealing rings 155 on both sides of the outer ring 151 are tightly fitted with the side wall of the inner groove 14 to form a preliminary seal. At the same time, the sealing plug 153 on the outer ring 151 just blocks the outer opening of the slot 13 to prevent water from leaking from the slot 13.
[0044] Then, the clamp 16 is wrapped around the water inlet pipe fitting 11, and the screw 163 is rotated to make one end enter the buckle groove 168. Then the nut 164 is tightened so that the first retaining ring 161 and the second retaining ring 162 hug the filter ring 15, which enhances the sealing effect and also prevents the filter ring 15 from accidentally coming out of the slot 13.
[0045] The clamping groove 167 in the retaining ring 161 and retaining ring 162 can clamp the outer ring 151, fix the filter ring 15, prevent the filter ring 15 from loosening, and also improve the sealing effect.
[0046] In some embodiments, after the first retaining ring 161 and the second retaining ring 162 are locked together, the sealing gasket 165 is pressed against the outer wall of the water inlet pipe fitting 11, and the front end of the sealing gasket 165 on the first retaining ring 161 and the second retaining ring 162 is tightly attached, further improving the sealing effect on the filter ring 15.
[0047] When irrigation is needed, the external controller activates the solenoid valve 1, and the water flows in from the inlet pipe 11. It first passes through the filter ring 15, where impurities in the water are intercepted by the filter screen 152. The filtered water then passes through the solenoid valve 1 and is discharged from the outlet pipe 12.
[0048] After the filter ring 15 has been used for a period of time, the filter ring 15 can be radially pulled out of the slot 13 by loosening the clamp 16;
[0049] In some embodiments, a new filter ring 15 is prepared. The filter ring 15 on the water inlet pipe 11 can be quickly pulled out without interrupting the water flow, and the new filter ring 15 can be quickly inserted into the slot 13 to complete the replacement of the filter ring 15. This replacement method does not require interrupting the water flow, thereby avoiding long-term interruption of the flow and affecting irrigation.
[0050] The old filter ring 15 is removed and the impurities on the filter screen 152 are cleaned by washing, and it is kept for the next use.
[0051] Therefore, the solenoid valve 1 integrates the filtration function into the inlet pipe 11 through an integrated design, eliminating the need for an additional external filtration device and greatly saving installation space.
[0052] The filter ring 15 is installed in the slot 13 of the water inlet pipe fitting 11 by radial insertion and is fixed by clamp 16. It is convenient and quick to disassemble and install, and the clamp 16 is designed on the water inlet pipe fitting 11, so there is no need to worry about the clamp 16 being lost.
[0053] Example 2: Refer to Figure 1 An intelligent irrigation solenoid valve with adjustable flow rate is basically the same as in Example 1, but with the addition that a water pressure sensor 2 is installed on the inlet pipe 11.
[0054] The water pressure sensor 2 can monitor the water pressure in the inlet pipe 11 in real time, thus facilitating flow rate adjustment. Flow rate adjustment can be achieved by setting new flow parameters through an external controller. After receiving the signal, the external controller controls the actuator of the solenoid valve 1 to change the position of the valve core, thereby adjusting the flow area and achieving flow rate adjustment. The water pressure sensor 2 continuously monitors water pressure changes and feeds the information back to the external controller. The external controller adjusts the opening of the solenoid valve 1 in real time according to the feedback signal to ensure that the flow rate is stable at the set value.
[0055] In one embodiment, when the water pressure value exceeds the preset alarm threshold, it is determined that the filter screen 152 is blocked, and an alarm is issued through the external controller to promptly replace or clean the filter ring 15.
[0056] In some embodiments, an overflow valve is installed on the water inlet pipe 11; when the filter screen 152 becomes clogged, the water pressure in the water inlet pipe 11 increases and exceeds the opening pressure of the overflow valve, the overflow valve can release the water pressure, and when the overflow valve sprays water, a visual reminder can be formed.
[0057] In some embodiments, the water pressure sensor 2 and the overflow valve are installed together on the inlet pipe 11, providing double protection.
[0058] This invention effectively intercepts impurities such as silt, aquatic plants, and plankton debris in irrigation water through the filter screen 152 of the filter ring 15, preventing these impurities from entering the solenoid valve 1. The recessed cavity 156 formed between the filter screen 152 and the inner diameter of the outer ring 151 faces the water inlet direction, making it easier for impurities to settle in the recessed cavity 156 under the action of water flow, reducing the accumulation of impurities on the filter screen 152, improving filtration efficiency, and preventing impurities from clogging the inside of the solenoid valve 1.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
