Description

Technical Field

[0001] This application relates to the field of filter technology, and more particularly to a magnetic filter. Background Technology

[0002] A magnetic filter is a device used to remove magnetic impurities from fluids. It uses magnetic materials to adsorb or capture magnetic particles and separate them from the fluid, thus completing the filtration of the fluid. After a period of use, the magnetic rod inside the magnetic filter needs to be removed for cleaning.

[0003] In related technologies, the water flow at both ends of the magnetic filter needs to be stopped before the magnetic rods can be removed for cleaning. However, starting and stopping the water flow results in significant energy loss, which is not conducive to long-term continuous filtration operations. Utility Model Content

[0004] This application provides a magnetic filter that solves the technical problem that the start and stop of water flow will cause a large amount of energy loss, which is not conducive to long-term continuous filtration operations.

[0005] To achieve the above objectives, the main technical solutions adopted in this application include:

[0006] This application provides a magnetic filter, which includes a valve body, a filter element, and a valve core. The valve body has an inlet channel and an outlet channel. The filter element is detachably disposed on the valve body and has a first receiving space. A magnetic component is disposed inside the filter element to adsorb magnetic particles in the first receiving space. The valve core has a first flow channel and a second flow channel. The first flow channel has a first end and a second end, and the second flow channel has a third end and a fourth end. Both the second end and the third end are connected to the first receiving space. The valve core also has a first blocking part and a second blocking part. The valve core is rotatably disposed on the valve body and has a use state and a maintenance state. When the valve core is in the use state, the first end is connected to the inlet channel and the fourth end is connected to the outlet channel. When the valve core is in the maintenance state, the first blocking part blocks the inlet channel and the second blocking part blocks the outlet channel.

[0007] The magnetic filter proposed in this application, when the valve core is under maintenance, has a first blocking part blocking the water inlet channel and a second blocking part blocking the water outlet channel. This isolates the filter element from the fluid, making it easy to maintain the filter element without affecting the operation of the entire fluid transmission system. This eliminates the need to restart the fluid transmission system, reduces energy consumption, and improves maintenance efficiency.

[0008] Optionally, the valve core is rotatably disposed in the valve body about a first axis, and the second end and the third end are disposed opposite each other along the extension direction of the first axis. The filter element has a first center line, which is perpendicular to the first axis.

[0009] Along the extension direction of the first axis, the second and third ends are arranged opposite each other, which makes the valve core design more neat, facilitates the assembly of the valve core into the valve body, and improves the assembly efficiency and operational stability of the magnetic filter.

[0010] Optionally, along the first direction, the first blocking part and the second blocking part are arranged opposite to each other. When the valve core is in the maintenance state, the first direction, the first center line and the first axis are perpendicular to each other. When the valve core is in the use state, the first direction is parallel to the first center line.

[0011] Along the first direction, the first blocking part and the second blocking part are arranged opposite to each other. In this way, when the valve core rotates and is subjected to water flow pressure, the force on the valve core can be more balanced, thereby reducing the probability of wear caused by uneven force on the valve core.

[0012] Optionally, both the first blocking part and the second blocking part are disposed on the outer surface of the valve core, and both the first blocking part and the second blocking part are recessed toward the center of the valve core.

[0013] Both the first and second blocking parts are recessed towards the center of the valve core, which provides the operator with a clear positioning and improves the operator's efficiency in switching the valve core state.

[0014] Optionally, the valve body includes a valve cavity, and the valve core is rotatably disposed in the valve cavity; the valve body is provided with a mounting hole, the mounting hole communicating with the valve cavity, the inner wall of the mounting hole having a first internal thread, and the outer peripheral surface of the filter element having a first external thread that mates with the first internal thread.

[0015] This allows the filter element to be rotated when the valve core is under maintenance, thus enabling it to be removed from the mounting hole in the valve body and improving the maintenance efficiency of the magnetic filter.

[0016] Optionally, the magnetic filter further includes a filter cover disposed in the first receiving space to divide the first receiving space into a first sub-receiving space and a second sub-receiving space, the first sub-receiving space being connected to a second end and the second sub-receiving space being connected to a third end.

[0017] In this way, after the magnetic impurities in the fluid are adsorbed by the magnetic components, the filter cover can further filter other impurities in the fluid, improve filtration efficiency and accuracy, remove impurities from the fluid more comprehensively, and ensure the quality of the filtered fluid.

[0018] Optionally, the second sub-accommodating space is arranged around the first sub-accommodating space.

[0019] This improves the utilization rate of the internal space of the filter element, making the structure of the filter element more compact.

[0020] Optionally, the magnetic filter further includes a first connector connected to the filter cover. The first connector has a connection channel, one end of which communicates with a first sub-accommodating space, and the other end of which communicates with a second end.

[0021] The first connector has a connection channel, one end of which is connected to the first sub-accommodating space, and the other end of which is connected to the second end. This allows impurities in the fluid to be filtered more thoroughly, improving the filtration performance of the magnetic filter.

[0022] Optionally, the valve body includes a valve cavity, a valve core is rotatably disposed in the valve cavity, the valve core and the inner wall surface of the valve cavity are at least partially spaced apart to form a conduction gap, and the third end is connected to the second sub-accommodating space through the conduction gap.

[0023] The third end is connected to the second sub-accommodating space through a conductive gap, which ensures smooth fluid flow when the valve core is in use, allowing the filtered fluid to flow along the designed path and ensuring thorough filtration.

[0024] Optionally, the valve body includes a valve body body, a first sealing cover and a second sealing cover. The valve body body defines a valve cavity. The first sealing cover has a first sealing cavity and the second sealing cover has a second sealing cavity. The valve core is rotatably disposed in the valve body about a first axis. Along the extension direction of the first axis, the first sealing cavity and the second sealing cavity are disposed opposite to each other. The first sealing cavity is connected to the second end and the first sub-accommodating space, respectively. The second sealing cavity is connected to the conduction gap and the third end, respectively.

[0025] In this way, when the valve core is in use, the first sealing cavity and the second sealing cavity are connected to each other, which can reduce the axial load on the valve core during rotation and make the valve core easier to rotate.

[0026] Optionally, the valve body further includes a first opening and a second opening, both of which communicate with the valve cavity. A first sealing cover is detachably disposed on the valve body to block the first opening, and a second sealing cover is detachably disposed on the valve body to block the second opening.

[0027] The magnetic filter also includes a first sealing cover and a second sealing cover. The first sealing cover is detachably disposed on the valve body to block the first opening, and the second sealing cover is detachably disposed on the valve body to block the second opening. This allows the first flow channel to be cleaned through the first opening and the second flow channel to be cleaned through the second opening, without having to disconnect the entire fluid system, reducing energy consumption and avoiding repeated start-stop phenomena.

[0028] Optionally, the magnetic filter also includes a first handle and a connector, a portion of which is disposed in the valve cavity and connected to the valve core, and the other portion of which passes through the valve body to connect to the first handle.

[0029] The design of the first handle allows the operator to easily rotate the valve core, improving the operator's efficiency. Attached Figure Description

[0062] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0064] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0065] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0066] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone.

[0068] Magnetic filters, as specialized devices for efficiently removing magnetic impurities from fluids, primarily utilize the adsorption properties of magnetic materials to capture and separate magnetic particles from the fluid, thereby achieving fluid purification and filtration. In numerous fields such as industrial production, water treatment, and food and beverage, magnetic filters, with their excellent magnetic impurity separation capabilities, effectively ensure the stable operation of production equipment and the reliability of product quality.

[0069] In practical applications, as the usage time increases, the magnetic rods inside the magnetic filter will attract a large amount of magnetic impurities. When a certain adsorption saturation is reached, the magnetic rods need to be removed and cleaned to restore their adsorption capacity. In related technologies, the traditional cleaning method requires first stopping the water flow at both ends of the magnetic filter. After the water flow has completely stopped, the relevant parts of the filter are disassembled, and the magnetic rods are removed for cleaning.

[0070] However, frequent start-ups and shutdowns of the water flow not only result in significant energy losses—starting the water flow system requires substantial electrical energy to power pumps and other equipment—but also put considerable stress on the entire fluid transport system, shortening equipment lifespan. Furthermore, the shutdown and cleaning process interrupts filtration operations, which is detrimental to long-term continuous production needs. This is particularly true for industries with extremely high requirements for production continuity, such as chemicals and pharmaceuticals, where shutdowns for cleaning can lead to decreased production efficiency, increased production costs, and potentially even impact product quality and production schedules.

[0071] In view of this, this application proposes a magnetic filter, which includes a valve body, a filter element, and a valve core. The valve body has an inlet channel and an outlet channel. The filter element is detachably disposed in the valve body and has a first receiving space. A magnetic component is disposed in the filter element to adsorb magnetic particles in the first receiving space. The valve core has a first flow channel and a second flow channel. The first flow channel has a first end and a second end, and the second flow channel has a third end and a fourth end. Both the second end and the third end are connected to the first receiving space. The valve core also has a first blocking part and a second blocking part. The valve core is rotatably disposed in the valve body and has a use state and a maintenance state. When the valve core is in the use state, the first end is connected to the inlet channel and the fourth end is connected to the outlet channel. When the valve core is in the maintenance state, the first blocking part blocks the inlet channel and the second blocking part blocks the outlet channel.

[0072] In the above scheme, when the valve core is under maintenance, the first blocking part blocks the water inlet channel and the second blocking part blocks the water outlet channel. This isolates the filter element and the fluid, making it easy to maintain the filter element without affecting the operation of the entire fluid transmission system. This eliminates the need to restart the fluid transmission system, reduces energy consumption, and improves maintenance efficiency.

[0073] It should be noted that the appendix Figure 1 To be continued Figure 8 These are schematic diagrams of the magnetic filter in use, with the first end connected to the inlet channel and the fourth end connected to the outlet channel. (Attached) Figure 9 To be continued Figure 13 These are all schematic diagrams of the magnetic filter under maintenance. The first blocking part blocks the water inlet channel, and the second blocking part blocks the water outlet channel.

[0076] Please refer to Figures 1 to 8In this embodiment, the magnetic filter 100 includes a valve body 110, a filter element 120, and a valve core 140. The valve body 110 has an inlet channel 111 and an outlet channel 112. The filter element 120 is detachably disposed in the valve body 110 and has a first receiving space 121. A magnetic component 130 is disposed in the filter element 120 to adsorb magnetic particles in the first receiving space 121. The valve core 140 is rotatably disposed in the valve body 110 and has a use state and a maintenance state. The valve core 140 has a first flow channel 141 and a second flow channel 142. The first flow channel 141 has a first... The valve core 140 has a first blocking part 143 and a second blocking part 144. When the valve core 140 is in use, the first end 141A is connected to the water inlet channel 111 and the fourth end 142B is connected to the water outlet channel 112. When the valve core 140 is under maintenance, the first blocking part 143 blocks the water inlet channel 111 and the second blocking part 144 blocks the water outlet channel 112.

[0077] The valve body 110 has an inlet channel 111 and an outlet channel 112. Fluid can enter the valve body 110 through the inlet channel 111 and then exit the valve body 110 through the outlet channel 112. The filter element 120 is equipped with a magnetic component 130, which is used to adsorb magnetic particles in the fluid. When the fluid passes through the filter element 120, it can be adsorbed by the magnetic component 130, thereby cleaning the magnetic particles. The filter element 120 is detachably installed on the valve body 110, so that after the filter element 120 has been used for a period of time, it can be disassembled for cleaning and maintenance.

[0078] The first flow channel 141 has a first end 141A and a second end 141B, and the second flow channel 142 has a third end 142A and a fourth end 142B. When the valve core 140 is in use, that is, when the fluid needs to flow through the filter element 120 so that the magnetic particles in the fluid are attracted by the magnetic component 130, the first end 141A is connected to the water inlet channel 111. The fluid enters the valve core 140 from the water inlet channel 111, and then flows from the first end 141A of the first flow channel 141 to the second end 141B, and then flows from the second end 141B to the first receiving space 121. After being attracted and filtered by the magnetic component 130, the fluid flows from the first receiving space 121 to the third end 142A and enters the second flow channel 142, and then flows out of the second flow channel 142 from the fourth end 142B.

[0079] When the valve core 140 is under maintenance, the first blocking part 143 on the valve core 140 blocks the water inlet channel 111, and the second blocking part 144 blocks the water outlet channel 112. The fluid in the water inlet channel 111 and the water outlet channel 112 is isolated from the first accommodating space 121, and the fluid in the water inlet channel 111 and the water outlet channel 112 cannot enter the valve body 110. This isolates the filter element 120 from the fluid, making it easy to maintain the filter element 120 without affecting the operation of the entire fluid transmission system. After removing the magnetic component 130, the filter element 120 can be disassembled and the impurities in the filter element 120 can be cleaned without restarting the fluid transmission system, reducing energy consumption and improving maintenance efficiency.

[0080] For example, the valve core 140 is rotatably disposed within the valve body 110. The valve core 140 rotates to switch between the use state and the maintenance state. During the rotation of the valve core 140, the orientation of the second end 141B and the third end 142A can remain unchanged, while the positions of the first end 141A and the fourth end 142B change. When the valve core 140 is in the maintenance state, the first blocking part 143 and the second blocking part 144 replace the positions of the first end 141A and the fourth end 142B to block the water inlet channel 111 and the water outlet channel 112.

[0081] In some embodiments, the filter element 120 may be a cup-shaped structure, with a recessed portion at the bottom of the filter element 120 that is recessed toward the interior of the first receiving space 121. A magnetic component 130 is disposed in the recessed portion of the filter element 120, thereby attracting magnetic particles by magnetic force. The magnetic component 130 is detachably disposed in the recessed portion.

[0082] Please refer to Figures 1 to 8 In this embodiment, the valve core 140 is rotatably disposed within the valve body 110 around the first axis 230. Along the extension direction Y of the first axis, the second end 141B and the third end 142A are disposed opposite to each other. The filter element 120 has a first center line 240, which is perpendicular to the first axis 230.

[0083] The valve core 140 is rotatably disposed within the valve body 110 about the first axis 230. The second end 141B and the third end 142A are disposed opposite each other in the extension direction Y of the first axis. That is to say, when the valve core 140 rotates, the positions of the second end 141B and the third end 142A will not change.

[0084] Along the extension direction Y of the first axis, the second end 141B and the third end 142A are arranged opposite each other, which makes the design of the valve core 140 more neat and facilitates the assembly of the valve core 140 into the valve body 110, thereby improving the assembly efficiency and operational stability of the magnetic filter 100.

[0085] Please refer to Figures 1 to 8 In this embodiment, along the first direction X, the first blocking part 143 and the second blocking part 144 are arranged opposite to each other. When the valve core 140 is in the maintenance state, the first direction X, the first center line 240 and the first axis 230 are perpendicular to each other. When the valve core 140 is in the use state, the first direction X is parallel to the first center line 240.

[0086] Along the first direction X, the first blocking part 143 and the second blocking part 144 are arranged opposite to each other. When the valve core 140 is under maintenance, the first blocking part 143 can block the water inlet channel 111, and the second blocking part 144 can block the water outlet channel 112. At this time, the first direction X can be parallel to the axial direction of the water inlet channel 111 and the axial direction of the water outlet channel 112, along the extension direction of the first center line 240. At this time, the first end 141A can face the first receiving space 121, and the fourth end 142B can face away from the first receiving space 121. Since the first direction X is perpendicular to the first axis 240, the space layout of the valve core 140 in the valve body 110 can be fully utilized, and the water inlet channel 111 and the water outlet channel 112 can be effectively blocked in a limited space, making the structure of the entire magnetic filter 100 more compact.

[0087] When the valve core 140 is in use, along the extension direction of the first center line 240, the first blocking part 143 is away from the filter element 120, and the second blocking part 144 is towards the filter element 120.

[0088] Furthermore, the first blocking part 143 and the second blocking part 144 are arranged opposite to each other along the first direction X. This way, when the valve core 140 rotates and is subjected to water flow pressure, the force on the valve core 140 can be more balanced, thereby reducing the probability of wear caused by uneven force on the valve core 140.

[0089] Please refer to Figures 1 to 13 In this embodiment, the first blocking part 143 and the second blocking part 144 are both disposed on the outer surface of the valve core 140, and the first blocking part 143 and the second blocking part 144 are both recessed toward the center of the valve core 140.

[0090] The first blocking portion 143 and the second blocking portion 144 are recessed toward the center of the valve core 140. This prevents the first blocking portion 143 and the second blocking portion 144 from colliding with the inner surface of the valve body 110 during the rotation of the valve core 140, making the rotation of the valve core 140 smoother. For example, the shape of the recess of the first blocking portion 143 and the second blocking portion 144 toward the center of the valve core 140 can be adapted to the opening contours of the water inlet channel 111 and the water outlet channel 112, respectively, so that the first blocking portion 143 blocks and seals the water inlet channel 111, and the second blocking portion 144 blocks and seals the water outlet channel 112. Furthermore, both the first blocking part 143 and the second blocking part 144 are recessed towards the center of the valve core 140, which provides the operator with a clear positioning. When the valve core 140 needs to be switched from the use state to the maintenance state, the first blocking part 143 needs to be rotated to the water inlet channel 111 and the second blocking part 144 needs to be rotated to the water outlet channel 112. After the first blocking part 143 is rotated to the water inlet channel 111 and the second blocking part 144 is rotated to the water outlet channel 112, the operator can stop rotating the valve core 140, thereby improving operating efficiency.

[0091] Please refer to Figure 5 The valve body 110 includes a valve cavity 113, and the valve core 140 is rotatably disposed in the valve cavity 113. The valve body 110 is provided with a mounting hole 114, which communicates with the valve cavity 113. The inner wall of the mounting hole 114 has a first internal thread 250, and the outer peripheral surface of the filter element 120 has a first external thread 251 that mates with the first internal thread 250.

[0092] The filter element 120 and the mounting hole 114 of the valve body 110 are connected by a first internal thread 250 and a first external thread 251. The filter element 120 is detachably disposed in the mounting hole 114 of the valve body 110. In this way, when the valve core 140 is in the maintenance state, the filter element 120 can be rotated, thereby allowing the filter element 120 to be removed from the mounting hole 114 of the valve body 110, thus improving the maintenance efficiency of the magnetic filter 100.

[0093] Please refer to Figures 1 to 13 In this embodiment, the magnetic filter 100 further includes a filter cover 150, which is disposed in the first accommodating space 121 to divide the first accommodating space 121 into a first sub-accommodating space 121A and a second sub-accommodating space 121B. The first sub-accommodating space 121A is connected to the second end 141B, and the second sub-accommodating space 121B is connected to the third end 142A.

[0094] The filter cover 150 is used to filter impurities in the fluid. When the fluid flows through the filter cover 150, impurities in the fluid cannot pass through the filter cover 150. The first receiving space 121 is divided into a first sub-receiving space 121A and a second sub-receiving space 121B by the filter cover 150. The first sub-receiving space 121A is located inside the filter cover 150, and the second sub-receiving space 121B is located outside the filter cover 150. The fluid flows from the second end 141B to the first sub-receiving space 121A, then flows through the filter cover 150 into the second sub-receiving space 121B, and then flows from the second sub-receiving space 121B to the third end 142A. Since the magnetic component 130 is disposed in the first sub-receiving space 121A, magnetic impurities in the fluid are attracted by the magnetic component 130. The filter cover 150 can further filter other impurities in the fluid, improve filtration efficiency and accuracy, remove impurities in the fluid more comprehensively, and ensure the quality of the filtered fluid.

[0095] Please refer to Figures 1 to 13 In this embodiment, the second sub-accommodating space 121B is arranged around the first sub-accommodating space 121A.

[0096] The second sub-accommodating space 121B is arranged around the first sub-accommodating space 121A. For example, the cross-sectional shape of the filter cover 150 in the length direction can be annular, and the cross-sectional shape of the first sub-accommodating space 121A and the second sub-accommodating space 121B can both be annular. In this way, the positions of the first sub-accommodating space 121A and the second sub-accommodating space 121B are reasonably allocated in a limited space, making the internal layout of the filter element 120 more compact. Without increasing the number of filter elements 120, more functional partitions are achieved, improving the space utilization efficiency and helping to make the structure of the filter element 120 more miniaturized and integrated.

[0097] The magnetic component 130 mainly adsorbs impurities in the first sub-accommodating space 121A. The filter cover 150 encloses the first sub-accommodating space 121A, so the impurities are concentrated in the first sub-accommodating space 121A. Thus, when cleaning the impurities in the filter element 120, only the impurities in the first sub-accommodating space 121A need to be cleaned, which improves the cleaning efficiency.

[0098] Please refer to Figures 1 to 13 In this embodiment, the magnetic filter 100 further includes a first connector 160, which is connected to the filter cover 150. The first connector 160 has a connection channel 161, one end of which is connected to the first sub-accommodating space 121A, and the other end of which is connected to the second end 141B.

[0099] The first connector 160 has a connection channel 161, through which fluid can flow from the second end 141B to the connection channel 161, and then from the connection channel 161 to the first sub-accommodating space 121A. In this way, the fluid can directly enter the first sub-accommodating space 121A from the connection channel 161, without flowing into the second sub-accommodating space 121B during the process of flowing into the first sub-accommodating space 121A. This ensures that all the fluid flows into the first sub-accommodating space 121A, is filtered by the filter cover 150, and is attracted by the magnetic component 130. Then, it flows from the first sub-accommodating space 121A to the second sub-accommodating space 121B, and from the second sub-accommodating space 121B to the third end 142A, so that impurities in the fluid are filtered more thoroughly, thereby improving the filtration performance of the magnetic filter 100.

[0100] Please refer to Figures 1 to 13 In this embodiment, the valve body 110 includes a valve cavity 113, and the valve core 140 is rotatably disposed in the valve cavity 113. The valve core 140 and the inner wall surface of the valve cavity 113 are at least partially spaced apart to form a conduction gap 170. The third end 142A is connected to the second sub-accommodating space 121B through the conduction gap 170.

[0101] The presence of the conduction gap 170 provides a channel for fluid to flow from the second sub-accommodating space 121B to the third end 142A, thus enabling the fluid passage of the entire filtration system. The fluid can smoothly enter the outlet channel from the second sub-accommodating space 121B through the conduction gap 170, ensuring smooth fluid flow when the valve core 140 is in use. This allows the filtered fluid to flow along the designed path, ensuring thorough filtration and improving the filtration capacity of the magnetic filter 100.

[0102] Please refer to Figures 1 to 13 The valve body 110 includes a valve body 115, a first sealing cover 200, and a second sealing cover 210. The valve body 115 defines a valve cavity 113. The first sealing cover 200 has a first sealing cavity 201, and the second sealing cover 210 has a second sealing cavity 211. The valve core 140 is rotatably disposed within the valve body 110 about a first axis 230. Along the extension direction Y of the first axis, the first sealing cavity 201 and the second sealing cavity 211 are disposed opposite to each other. The first sealing cavity 201 is connected to the second end 141B and the first sub-accommodating space 121A, respectively. The second sealing cavity 211 is connected to the conducting gap 170 and the third end 142A, respectively.

[0103] Fluid can flow from the inlet channel 111 to the first end 141A, then from the first end 141A to the second end 141B, from the second end 141B to the first sealing cavity 201, from the first sealing cavity 201 to the first sub-accommodating space 121A, from the first sub-accommodating space 121A to the second sub-accommodating space 121B, from the second sub-accommodating space 121B to the guiding gap 170, from the guiding gap 170 to the second sealing cavity 211, and from the second sealing cavity 211 to the third end 142A. In this way, when the valve core 140 is in use, the first sealing cavity 201 and the second sealing cavity 211 are connected to each other, which reduces the axial load on the valve core 140 during rotation, making the valve core 140 easier to rotate.

[0104] Please refer to Figures 1 to 13 In this embodiment, the valve body 110 further includes a first opening 180 and a second opening 190, both of which are connected to the valve cavity 113. A first sealing cover 200 is detachably disposed on the valve body 110 to block the first opening 180, and a second sealing cover 210 is detachably disposed on the valve body 110 to block the second opening 190.

[0105] Both the first opening 180 and the second opening 190 are connected to the valve cavity 113. Along the extension direction Y of the first axis, the first opening 180 and the second opening 190 can be arranged opposite to each other. The first opening 180 can be arranged opposite to the second end 141B, and the second opening 190 can be arranged opposite to the third end 142A. During the rotation of the valve core 140, the second end 141B always faces the first opening 180, and the third end 142A always faces the second opening 190.

[0106] A first sealing cap 200 is detachably disposed on the valve body 110 to seal the first opening 180. For example, the first sealing cap 200 can be connected to the valve body 110 by a threaded connection to seal the first opening 180. A second sealing cap 210 is detachably disposed on the valve body 110 to seal the second opening 190. For example, the second sealing cap 210 can be connected to the valve body 110 by a threaded connection to seal the second opening 190.

[0107] When the valve core 140 is in use, the first sealing cover 200 blocks the first opening 180, and the second sealing cover 210 blocks the second opening 190. Fluid will not flow out of the valve chamber 113 from the first opening 180 and the second opening 190. When the valve core 140 is rotated to the maintenance state, the first blocking part 143 blocks the water inlet channel 111, and the second blocking part 144 blocks the water outlet channel 112. In this way, fluid will not enter the valve chamber 113. That is to say, the first sealing cover 200 can be removed from the first opening 180, and the second sealing cover 210 can be removed from the second opening 190. This allows the first flow channel 141 to be cleaned through the first opening 180, and the second flow channel 142 to be cleaned through the second opening 190. There is no need to disconnect the entire fluid system, reducing energy consumption and avoiding repeated start-stop phenomena.

[0108] Please refer to Figures 1 to 13 In this embodiment, the magnetic filter 100 further includes a first handle 220 and a connector 221. A portion of the connector 221 is disposed in the valve cavity 113 and connected to the valve core 140, and the other portion of the connector 221 passes through the valve body 110 to be connected to the first handle 220.

[0109] For example, the connector 221 is detachably disposed on the valve body 110, and the connector 221 can be detached from the valve body 110 when the magnetic filter 100 needs maintenance.

[0110] The first handle 220 allows the operator to easily rotate the valve core 140. By directly operating the handle, the valve core 140 can be easily switched between the working state and the maintenance state without the need for other complicated tools. This improves the convenience of operation, reduces operation time and labor intensity, and makes the daily maintenance and use of the magnetic filter 100 simpler and more efficient.

[0111] For example, such as Figure 2 As shown, the valve core 140 and the magnetic filter 100 are in use at this time. Figure 9 As shown, at this time, valve core 140 is in maintenance mode, magnetic filter 100 is in maintenance mode, and first handle 220 is... Figure 2 Rotate the position in the middle to Figure 9 The position of the valve core 140 is determined, thereby enabling the switching of the valve core 140 from the service state to the maintenance state.
