However, liquids often contain solid impurities, which not only affect equipment using the liquid and reduce its service life, but can also clog valves over time. To solve this problem, a filter valve has been proposed that can filter larger particles in the liquid through a filter screen, thereby improving the quality of the liquid exiting the pipeline. However, existing filter valves require regular cleaning of the filter screen, and the disassembly and assembly of the filter screen is inconvenient, hindering later maintenance.

[0003] Therefore, there is an urgent need for a filter valve that can solve the problem of inconvenient filter screen disassembly. Utility Model Content

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0036] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0039] This embodiment provides a filter valve, such as Figures 1-6 As shown, the filter valve includes a valve body 10 and a filter assembly 30. The valve body 10 has an axially oriented flow channel 11 and a filter chamber 12 communicating with the flow channel 11. The filter chamber 12 has an assembly port 14. The filter assembly 30 includes a filter screen 31 and a sealing seat 32. The filter screen 31 is disposed on the sealing seat 32 and extends into the filter chamber 12 from the assembly port 14. The sealing seat 32 is detachably and sealingly inserted into the assembly port 14 of the filter chamber 12.

[0040] In the above structure, the liquid to be filtered can enter the filter chamber 12 through the flow channel 11; and the filter chamber 12 is equipped with a filter screen 31, which can filter large particles in the liquid to be filtered, thereby improving the quality of the liquid exiting through the other end of the flow channel 11 and ensuring good performance. Furthermore, after long-term filtration, the filter screen 31 needs to be cleaned. The filter screen 31 is set on the sealing seat 32, which is detachably connected to the valve body 10. Therefore, when the sealing seat 32 is removed, the filter screen 31 can be taken out from the valve body 10 together, thereby improving the disassembly efficiency. At the same time, when reinstalling after cleaning, the filter screen 31 can be directly inserted back into the filter chamber 12 through the assembly port 14 by holding the sealing seat 32. The sealing seat 32 can reseal the filter chamber 12 and then restart the filtration operation.

[0041] In addition, such as Figures 1-6 As shown, to improve the ease of disassembly and assembly of the filter assembly 30, the filter valve also includes a limiting component to prevent the filter assembly 30 from falling off. The limiting component includes a plug hole 13, a limiting groove 322, and a plug member 40. The plug hole 13 is opened on the assembly port 14 and penetrates the inner wall of the assembly port 14. The limiting groove 322 is provided on the sealing seat 32, and the plug hole 13 and the limiting groove 322 are correspondingly provided. The plug member 40 can be inserted into the plug hole 13, and at least part of the plug member 40 is simultaneously limited in the plug hole 13 and the limiting groove 322.

[0042] In this structure, when installing the filter assembly 30, the filter screen 31 is first inserted directly into the filter chamber 12 through the sealing seat 32. At this time, the sealing seat 32 is located in the assembly port 14. Then, the connector 40 is inserted into the insertion hole 13 and cooperates with the limiting groove 322 on the sealing seat 32 in the assembly port 14 to limit the sealing seat 32, thereby fixing the filter screen 31 in the filter chamber 12. When disassembly is required, the operator only needs to pull the connector 40 out from the insertion hole 13 and the limiting groove 322. At this time, the connector 40 is no longer simultaneously limited in the insertion hole 13 and the limiting groove 322, so the sealing seat 32 can be directly removed from the assembly port 14. The filter screen 31 is fixed on the sealing seat 32, and the sealing seat 32 carries the filter screen 31 out of the filter chamber 12, thus completing the disassembly. This simplifies the overall structure, reduces the difficulty of disassembly and assembly, and thus improves the speed of disassembly and assembly.

[0043] To ensure a good sealing effect, such as Figure 3As shown, the sealing seat 32 has a sealing groove 324 arranged circumferentially, and the sealing groove 324 is located on the side of the limiting groove 322 near the filter screen 31. A sealing element 60 is provided in the sealing groove 324. By providing the sealing element 60, liquid can be prevented from flowing out of the gap between the sealing seat 32 and the assembly port 14, ensuring good airtightness. In addition, the sealing seat 32 also has a sealing groove 324 arranged circumferentially, and the sealing element 60 can be directly installed in the sealing groove 324, thereby ensuring that the sealing element 60 will not move during installation and disassembly, thus ensuring good disassembly and assembly effect. In addition, the sealing groove 324 is located on the side of the limiting groove 322 near the filter screen 31, which can also prevent liquid in the filter chamber 12 from flowing out of the insertion hole 13, thus again ensuring good sealing performance. It should be noted that in this embodiment, the sealing element 60 is an O-ring. O-rings have a simple structure, low price, and are easy to install, which helps to reduce manufacturing costs and operational difficulty.

[0044] Specifically, such as Figures 1-6 As shown, the limiting groove 322 is an annular groove, and the connector 40 has a U-shaped structure, including two connector parts 41 and a connecting rod 42. The two connector parts 41 are connected by the connecting rod 42, and each connector part 41 corresponds to a connector hole 13. Both connector parts 41 can be simultaneously inserted into the corresponding connector holes 13. In this structure, firstly, since the limiting groove 322 is an annular groove, no matter how the sealing seat 32 is rotated during installation, the connector 40 can directly enter the limiting groove 322 after being inserted into the connector hole 13, thereby improving installation efficiency and convenience. Secondly, since the connector 40 is U-shaped, during installation, the connector parts 41 at both ends can be aligned with the two connector holes 13 by holding the connecting rod 42, and the two connector parts 41 can be simultaneously inserted and fixed, making the operation simple and convenient and improving installation efficiency. When the filter assembly 30 needs to be removed for cleaning, simply pull the connecting rod 42 away from the valve body 10 to pull out both plugs 41 at the same time. Then, pull the sealing seat 32 outward from the filter chamber 12 to complete the disassembly, which greatly improves convenience.

[0045] In addition, such as Figures 1-3 As shown, a reverse fastener 323 is also provided on the outer periphery of the sealing seat 32. The reverse fastener 323 can abut against the connecting rod 42 to prevent the sealing seat 32 from falling out of the filter chamber 12 and from rotating around its axis. In this structure, the reverse fastener 323 can abut against the connecting rod 42 of the plug-in 40, thereby preventing the plug-in 40 from falling out of the plug hole 13, and thus indirectly ensuring that the sealing seat 32 will not fall out of the valve body 10; in addition, when the sealing seat 32 tends to rotate around its axis, the plug-in 40 can abut against the reverse fastener 323 in the opposite direction, thereby preventing the sealing seat 32 from rotating and ensuring the stability of the structure.

[0046] Considering that other impurities may exist in the liquid to be filtered, such as iron filings that cannot be filtered by filter screen 31, therefore, Figure 3 As shown, the filter assembly 30 also includes a magnetic suction element 33, which is disposed on the sealing seat 32. By providing the magnetic suction element 33, when the liquid to be filtered passes through the filter screen 31, the magnetic suction element 33 can effectively adsorb iron filings and impurities, thereby ensuring the quality of the liquid exiting from the other end of the flow channel 11. Since the magnetic suction element 33 is disposed on the sealing seat 32, it can be disassembled together with the filter screen 31 and the sealing seat 32. During installation, the filter screen 31 and the magnetic suction element 33 can be directly inserted into the filter chamber 12 through the sealing seat 32, thus ensuring efficient disassembly and assembly and reducing the difficulty of disassembly and assembly.

[0047] like Figure 5 and Figure 6 As shown, the sealing base 32 is provided with a mounting hole 321, and the magnetic attractor 33 is detachably installed in the mounting hole 321. By providing the mounting hole 321, the connection between the magnetic attractor 33 and the sealing base 32 is simplified. During installation, the magnetic attractor 33 can be simply inserted into the mounting hole 321 for fixation. For cleaning, it can be simply pulled out of the mounting hole 321. The operation is simple and convenient, and it facilitates cleaning of the magnetic attractor 33. It is worth noting that in this embodiment, the magnetic attractor 33 is a magnetic rod, which has a large volume and strong magnetic force, enabling it to fully attract iron filings in the liquid.

[0048] Specifically, such as Figure 5 and Figure 6 As shown, the filter screen 31 is arranged around the outer periphery of the mounting hole 321. This structure can improve space utilization and further increase the effective filtration area of ​​the filter screen 31, thereby ensuring a good filtration effect.

[0049] However, this structure presents a problem: it makes it inconvenient to install and remove the magnetic component 33 from the sealing seat 32, leading to difficulties in cleaning. To solve this problem, such as... Figure 5 and Figure 6 As shown, a notch 311 is provided on one side of the filter screen 31, through which the magnetic component 33 can be directly replaced. This structure allows operators to easily remove the magnetic component 33 through the notch 311, thereby enabling timely cleaning of the magnetic component 33. During the replacement process, the filter screen 31 will not interfere with the operator's arm, and it is also convenient to reinstall the cleaned or new magnetic component 33 onto the sealing seat 32, thereby improving cleaning efficiency and enhancing the user experience.

[0050] In addition, such as Figure 5 and Figure 6As shown, the outer periphery of the filter screen 31 is provided with reinforcing ribs 312. By providing reinforcing ribs 312, the structural strength of the filter screen 31 can be effectively improved, thereby avoiding the decrease in pressure bearing capacity after the notch 311 is provided, and ensuring that it will not deform even after long-term use, thus improving the service life of the filter screen 31.

[0051] Finally, it should be noted that, as Figure 3 and Figure 4 As shown, in this embodiment, the filter valve further includes a sealing ball 20, which is disposed within the filter chamber 12. The sealing ball 20 has a cavity 23 inside and an opening 22 at its bottom. The opening 22 communicates with both the cavity 23 and the assembly port 14. The filter assembly 30 can be installed within the cavity 23 through the opening 22. The sealing ball 20 also has a through hole 21. When the through hole 21 coincides with the flow channel 11, the sealing ball 20 is in the communicating position, allowing the liquid to be filtered to enter the cavity 23 and be filtered by the filter screen 31 and the magnetic suction component 33, finally flowing out from the other end. When the through hole 21 does not coincide with the flow channel 11, the sealing ball 20 is in the closed position, thus blocking the liquid to be filtered and preventing it from entering the cavity 23.

[0052] To facilitate switching between the closed and open positions of the sealing ball 20, a valve stem 70 is connected to the top of the sealing ball 20. The other end of the valve stem 70 extends out of the valve body 10 and is connected to a handle 50. The handle 50 drives the valve stem 70 to rotate, which in turn indirectly drives the sealing ball 20 to switch between the open and closed positions, saving time and effort and making it easy to use. In addition, a sealing element 60 is also provided between the valve stem 70 and the valve body 10 to ensure a good seal for the filter chamber 12. The structure of the sealing element 60 has been described above and will not be repeated here.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
