Description

Technical Field

[0001] This utility model relates to the field of solenoid valve technology, and in particular to an anti-clogging solenoid valve. Background Technology

[0002] A solenoid valve is an industrial automation actuator that uses electromagnetic effect to control the movement of the valve core, thereby achieving automatic control of the flow, direction, or flow of fluids (gas, liquid, etc.). It is mainly composed of components such as solenoid coil, valve core, valve body, and spring, and is widely used in petrochemical, water treatment, HVAC systems, medical devices, automobile manufacturing and other fields.

[0003] In related technologies, the selection of solenoid valves needs to be tailored to different operating conditions. For example, in scenarios where the medium contains impurities, a filter screen or filter element is usually installed inside the solenoid valve to intercept solid particles, debris, and other impurities in the medium, preventing impurities from entering the valve core and causing valve core jamming, sealing surface wear, or flow channel blockage. However, after prolonged use, a large amount of impurities will remain on the filter screen or filter element, causing filter screen blockage, resulting in a decrease in fluid flow velocity and affecting overall conveying efficiency. At the same time, solenoid valves are often connected to pipelines via flanges, and the entire removal process for cleaning and replacing the filter screen is cumbersome and time-consuming, increasing maintenance costs. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to propose an anti-clogging solenoid valve that can use the impact force of water flow to self-clean the filter canister, reducing the workload of frequent manual cleaning. At the same time, with the threaded connection design between the connector and the vertical pipe, the filter canister can be easily removed for deep cleaning or impurity discharge, thus extending the service life of the solenoid valve.

[0006] To achieve the above objectives, the first aspect of this utility model provides an anti-clogging solenoid valve, comprising: a main pipe body, a solenoid valve body, and an anti-clogging mechanism, wherein the solenoid valve body is disposed on the main pipe body; the filter assembly is disposed in the main pipe body through the vertical pipe; and the sealing assembly is disposed in the vertical pipe.

[0007] In addition, the anti-clogging solenoid valve proposed above according to this utility model may also have the following additional technical features: Specifically, the filtration assembly includes a housing, a connector, a filter canister, and a cleaning assembly. The housing is disposed inside the vertical pipe, with its top end extending through into the main pipe. The connector is disposed inside the vertical pipe via the housing. The filter canister is disposed on the housing. The cleaning assembly is disposed on the housing.

[0008] Specifically, the cleaning assembly includes a brush plate and a blade assembly, wherein the brush plate is disposed on the housing; and the blade assembly is disposed at equal intervals on the outer wall of the filter barrel.

[0009] Specifically, the connector is provided with an external thread, and the vertical tube is provided with an internal thread, wherein the external thread on the connector is adapted to the internal thread in the vertical tube.

[0010] Specifically, the sealing assembly includes an annular rubber ring and an annular step block, wherein the annular rubber ring is disposed on the inner wall of the vertical pipe; and the annular step block is disposed on the outer wall of the housing.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The anti-clogging solenoid valve of the present invention filters impurities in the liquid through the filter barrel, preventing impurities from adhering to key parts such as the valve core or flow channel, avoiding problems such as valve core jamming and sealing failure, thereby extending the service life of the solenoid valve. In use, the water flow will impact the blade assembly, causing it to drive the filter barrel to rotate synchronously. The rotating filter barrel contacts the fixed brush plate, allowing the brush plate to clean the surface of the filter barrel, preventing the filter holes from being blocked by impurities, and ensuring that the filter barrel always maintains good filtration efficiency. At the same time, the connector and the vertical pipe adopt a threaded connection design. When deep cleaning is required, the filter barrel can be removed from the valve body by rotating the connector, making it convenient to discharge the impurities accumulated inside the solenoid valve.

[0015] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0016] The anti-clogging solenoid valve of this utility model is described below with reference to the accompanying drawings.

[0017] like Figures 1-4 As shown, an anti-clogging solenoid valve according to an embodiment of the present invention may include: a main body 1, a solenoid valve body 2 and an anti-clogging mechanism 3, wherein the solenoid valve body 2 is disposed on the main body 1.

[0018] It should be noted that the solenoid valve body 2 described in this embodiment consists of a valve body shell, a valve core, an electromagnetic drive unit, and a seal. The valve body shell provides installation support and protection space for the internal components. The valve core is used to control the on / off state of the fluid. The electromagnetic drive unit drives the valve core to move through electromagnetic force. The seal is set at the mating part between the valve core and the valve body to prevent fluid leakage.

[0019] Additionally, it should be noted that the main body 1 described in this embodiment is provided with a valve seat, which is adapted to the valve core of the solenoid valve body 2. When the valve core is activated by the electromagnetic drive unit, it can be engaged or disengaged to realize the opening and closing control of the fluid channel in the main body 1.

[0020] The anti-clogging mechanism 3 includes a vertical pipe 31, a filter assembly 32, and a sealing assembly 33. The vertical pipe 31 is installed on the main body 1, the filter assembly 32 is installed inside the main body 1 through the vertical pipe 31, and the sealing assembly 33 is installed inside the vertical pipe 31.

[0021] It should be noted that the vertical pipe 31 described in this embodiment is connected to the main pipe 1, so that the filter component 32 can penetrate into the main pipe 1 to effectively intercept impurities in the fluid.

[0022] Specifically, during use, by opening the solenoid valve body 2, the electromagnetic drive unit inside the solenoid valve body 2 generates magnetism, which in turn drives the valve core to move away from the valve seat inside the main body 1, thereby opening the fluid channel inside the main body 1 and allowing the fluid to begin flowing inside the main body 1.

[0023] At this time, the filter assembly 32 installed in the main pipe 1 simultaneously intercepts impurities in the flowing fluid, preventing impurities from adhering to key parts such as valve cores or flow channels and affecting equipment operation. Meanwhile, the sealing assembly 33 in the vertical pipe 31 seals the gap between the filter assembly 32 and the vertical pipe 31 to prevent liquid from seeping out from the gap.

[0024] In one embodiment of this utility model, such as Figure 2 As shown, the filter assembly 32 includes a housing 321, a connector 322, a filter barrel 323, and a cleaning assembly 324. The housing 321 is disposed inside the vertical pipe 31, and the top end of the housing 321 extends through into the main pipe 1. The connector 322 is disposed inside the vertical pipe 31 through the housing 321. The filter barrel 323 is disposed on the housing 321, and the cleaning assembly 324 is disposed on the housing 321.

[0025] It should be noted that the top of the housing 321 described in this embodiment is provided with a rubber pad. When the top of the housing 321 extends into the main pipe 1, the rubber pad at the extended end can fit tightly with the bottom end of the valve seat in the main pipe 1, which not only achieves the seal between the housing 321 and the valve seat to prevent fluid from leaking from the gap between them, but also provides a through groove at the end of the housing 321 facing the water inlet of the main pipe 1, so that the fluid can flow through the through groove into the filter bucket 323, thereby improving the filtration effect of the filter bucket 323.

[0026] Specifically, when the fluid channel inside the main body 1 is opened, the fluid will flow into the filter barrel 323 through the through groove of the housing 321, so that the filter barrel 323 intercepts the impurities in the fluid. The intercepted impurities will remain outside the filter barrel 323. At the same time, the filtered fluid passes through the valve seat and flows out from the outlet of the main body 1.

[0027] At the same time, the cleaning component 324 can brush off the impurities attached to the surface of the filter holes, preventing the filter holes from becoming clogged and causing a decrease in filtration efficiency, thereby ensuring the stable operation of the filter canister 323.

[0028] In one embodiment of this utility model, such as Figure 4 As shown, the cleaning component 324 includes a brush plate 3241 and a blade assembly 3242. The brush plate 3241 is disposed on the housing 321, and the blade assembly 3242 is disposed at equal intervals on the outer wall of the filter barrel 323.

[0029] It should be noted that the filter barrel 323 described in this embodiment is rotatably connected to the housing 321 via a bearing, and the outer surface of the filter barrel 323 is in contact with the brush plate 3241 to ensure that the brush plate 3241 can clean impurities from the outer wall of the filter barrel 323.

[0030] Additionally, it should be noted that the blade assembly 3242 described in this embodiment is inclined, thereby increasing the contact area between the blade assembly 3242 and the water flow, ensuring that the water flow impact force can effectively drive the filter barrel 323 to rotate.

[0031] Specifically, when fluid flows into the filter barrel 323 through the channel of the housing 321, the flowing water impacts the blade assembly 3242 on the outer wall of the filter barrel 323, causing the blade assembly 3242 to drive the filter barrel 323 to rotate. Then, the bristles of the brush plate 3241 continuously brush the filter holes on the outer wall of the filter barrel 323, brushing off the impurities attached to the surface of the filter holes in time, and preventing impurities from clogging the filter holes.

[0032] In one embodiment of this utility model, such as Figure 3 As shown, the connector 322 is provided with an external thread, and the vertical tube 31 is provided with an internal thread. The external thread on the connector 322 is compatible with the internal thread in the vertical tube 31.

[0033] It should be noted that the connector 322 described in this embodiment is rotatably connected to the housing 321 via a bearing, so that the connector 322 does not restrict the operation of the housing 321 and the filter canister 323, thus ensuring the stable realization of the self-cleaning function.

[0034] Specifically, when it is necessary to clean the filter assembly 32, the threaded connection between the connector 322 and the vertical tube 31 can be released by screwing the connector 322, and the entire filter assembly 32 can be taken out from the vertical tube 31, which is convenient to operate.

[0035] In one embodiment of this utility model, such as Figure 3 As shown, the sealing assembly 33 includes an annular rubber ring 331 and an annular step block 332, wherein the annular rubber ring 331 is disposed on the inner wall of the vertical pipe 31 and the annular step block 332 is disposed on the outer wall of the housing 321.

[0036] It should be noted that the shape of the annular step block 332 described in this embodiment is adapted to the inner ring of the annular rubber ring 331, so that the annular step block 332 can achieve a seal when it is in contact with the annular rubber ring 331, effectively preventing fluid from leaking from the gap between the vertical pipe 31 and the housing 321.

[0037] Specifically, after the filter assembly 32 is installed in the vertical pipe 31 through the connector 322, the annular step block 332 will fit tightly with the annular rubber ring 331. During the fitting process, the annular rubber ring 331 undergoes elastic deformation under the squeezing action of the annular step block 332, thereby sealing the gap between the vertical pipe 31 and the housing 321, preventing the fluid in the main body 1 from leaking out from the gap between the vertical pipe 31 and the housing 321, and ensuring the overall sealing of the equipment.

[0038] In summary, the anti-clogging solenoid valve of this utility model filters impurities in the liquid through a filter barrel, preventing impurities from adhering to key parts such as the valve core or flow channel, thus avoiding problems such as valve core jamming and sealing failure, thereby extending the service life of the solenoid valve. During use, the water flow impacts the blade assembly, causing it to rotate synchronously with the filter barrel. The rotating filter barrel contacts the fixed brush plate, allowing the brush plate to clean the surface of the filter barrel, preventing the filter holes from being blocked by impurities and ensuring that the filter barrel always maintains good filtration efficiency. At the same time, the connector and the vertical pipe adopt a threaded connection design. When deep cleaning is required, the filter barrel can be removed from the valve body by rotating the connector, making it easy to remove impurities accumulated inside the solenoid valve.
