[0041] To ensure the liquid quality when pipeline delivers liquid, such as Figures 1-3As shown, the filter valve provided in the present example comprises a valve body 100 and a filter assembly. The valve body 100 is provided with a flow channel 110 in the axial direction. The valve body 100 is provided with a filter cavity 120 in the direction perpendicular to the flow channel 110. The filter cavity 120 has an external end. A filter screen 10 can be inserted into the filter cavity 120. A base 20 is detachably and sealingly connected to the external end. Specifically, the filter cavity 120 is provided with a sealing ball 130. The top end of the sealing ball 130 is connected with a valve rod 140. The part of the valve rod 140 outside the valve body 100 is connected with a handle 150. The sealing ball 130 is internally provided with the filter assembly. The handle 150 can be rotated to drive the sealing ball 130 to rotate through the valve rod 140, so that the sealing ball 130 can be connected with the flow channel 110 or cut off the flow channel 110. When the sealing ball 130 is rotated to the position where the flow channel 110 is connected, the liquid can enter the inner wall of the sealing ball 130. At this time, the filter assembly filters the liquid. The filtered liquid can flow out through the flow channel 110, so as to ensure the quality of the liquid. However, the existing filter assembly is not only inconvenient to install and disassemble, but also troublesome to clean and inconvenient to maintain in the later period.

[0042] To solve this problem, the present embodiment further provides a filter assembly, as shown in Figure 4 and Figure 5 , which is installed in the filter valve and used for filtering the liquid passing through the filter valve. Specifically, the filter assembly comprises a filter screen 10, a base 20 and a magnetic member 30. The filter screen 10 comprises a first body 15 and a second body 16 connected with each other, which form a surrounding structure. One side of the first body 15 and the second body 16 is fixed to the base 20. The magnetic member 30 is detachably connected to the side of the base 20 connected with the filter screen 10. The filter screen 10 surrounds the outer periphery of the magnetic member 30. The height of the first body 15 is greater than the height of the second body 16, so as to form an opening 11. Through the opening 11, the magnetic member 30 can be directly replaced.

[0043] In the above structure, since the filter screen 10 and the magnetic member 30 are arranged on the base 20, when the filter assembly needs to be disassembled from the filter cavity 120, the base 20 is only needed to be removed from the valve body 100, and then the filter screen 10 and the magnetic member 30 can be taken out together, so that the convenience of disassembly before cleaning is greatly improved. After the filter assembly is disassembled from the filter cavity 120, since the opening 11 formed by the first body 15 and the second body 16 is arranged on the filter screen 10, the operator can clean the area surrounded by the filter screen 10 through the opening 11, and the magnetic member 30 can also be directly disassembled through the opening 11, so that the disassembled magnetic member 30 can be cleaned, and the convenience of operation is improved. When the cleaning is completed, the new magnetic member 30 or the cleaned magnetic member 30 can be reinstalled on the base 20 through the opening 11, and after installation, the operator can reinsert the filter screen 10 and the magnetic member 30 into the filter cavity 120 by holding the base 20, so that normal operation is ensured.

[0044] Specifically, as shown in Figure 4 and Figure 5 , the filter screen 10 is provided with a top notch 12 at one end away from the base 20, the first body 15 is higher than the second body 16 to form a side notch 13, and the top notch 12 and the side notch 13 jointly form the opening 11. In this structure, the opening degree of the opening 11 can be reasonably controlled by arranging the top notch 12 and the side notch 13, so that the filter screen 10 and the magnetic member 30 can be conveniently cleaned, and the filtering effect of the liquid can be ensured. Moreover, the height of the first body 15 is less than the height of the second body 16, and the side notch 13 is naturally formed between them, so that the processing difficulty is reduced. It should be noted that, as shown in Figure 3 , the opening 11 of the filter screen 10 needs to face the liquid inlet direction of the flow channel 110, so that the filter screen 10 can produce good filtering effect, and the normal flow of the liquid can be ensured.

[0045] In addition, as shown in Figure 4 and Figure 5 , the edges of the top notch 12 and the side notch 13 are provided with reinforcing ribs 14. Since the top notch 12 and the side notch 13 will reduce the structural strength of the filter screen 10, the reinforcing ribs 14 arranged at the edges of the top notch 12 and the side notch 13 can increase the structural strength of the filter screen 10, thereby increasing the pressure-bearing capacity, and also avoiding scratching the arms of the cleaning personnel when the filter screen 10 and the magnetic member 30 are cleaned, so that the safety of use is ensured.

[0046] In addition, as shown in Figure 4 and Figure 5As shown, the connection between the first body 15 and the second body 16 is provided with a reinforcing rib 14. Such a structure can improve the connection strength of the first body 15 and the second body 16, avoid cracking or bending of the connection between the first body 15 and the second body 16 under the impact of liquid, and thus improve the service life of the filter screen 10.

[0047] In addition, as shown in Figure 4 and Figure 5 As shown, the first body 15 and the second body 16 are provided with a plurality of reinforcing ribs 14 in the axial and circumferential directions. Such a structure can greatly improve the pressure resistance of the filter screen 10 by using reinforcing ribs 14 in the axial and circumferential directions, thereby avoiding excessive pressure of the liquid from causing the filter screen 10 to be bent, reducing the deformation amount of the filter screen 10 after use, thereby facilitating disassembly and installation, and thus improving the service life of the filter screen 10.

[0048] As shown in Figure 5 The base 20 is provided with a mounting hole 21 on the side close to the filter screen 10, and the magnetic attraction member 30 is detachably arranged in the mounting hole 21. Such a structure can simplify the connection structure of the magnetic attraction member 30 and the base 20, thereby reducing the processing cost, and at the same time, the mounting hole 21 can ensure the fixing effect of the magnetic attraction member 30, avoid shaking or tilting of the magnetic attraction member 30, and thus ensure good use effect.

[0049] It should be noted that in the present embodiment, the mounting hole 21 is located at the center position of the base 20, which makes the magnetic attraction member 30 as much as possible to attract the iron filings in the sealing ball 130, thereby ensuring the liquid quality at the end of the pipeline. In addition, the magnetic attraction member 30 is a magnetic rod, which has a regular shape, is convenient to install, has a larger area for magnetic attraction, and can as much as possible attract the iron filings in the liquid.

[0050] In order to ensure good sealing performance, as shown in Figures 3-5 The base 20 is provided with a sealing groove 22 in the circumferential direction, and the sealing groove 22 is used to install a sealing member 40. After the filter assembly is installed into the valve body 100, the sealing member 40 can seal the base 20 and the valve body 100, thereby effectively preventing liquid from leaking from the gap between the base 20 and the valve body 100, and thus ensuring good sealing performance. In addition, since the sealing member 40 is installed in the sealing groove 22, the sealing groove 22 can limit the sealing member 40, and thus when the base 20 is disassembled, the sealing member 40 will not shake, effectively improving the disassembly efficiency and convenience. It should be noted that the sealing member 40 is an O-shaped sealing ring, which has a simple structure, low price, corrosion resistance, and good sealing effect.

[0051] In order to further improve the convenience of disassembly and assembly, as shown in Figures 2-5As shown, the base 20 is further provided with a limiting groove 23 in the circumferential direction, which is used to install the filter assembly in the valve body 100. In this embodiment, the installation of the filter assembly needs to pass through the plug-in part 50, which can pass through the valve body 100 of the filter valve and can be plugged into the limiting groove 23, so that the filter assembly can be installed in the valve body 100 and cannot fall off. When cleaning is needed, only the plug-in part 50 needs to be pulled out, and the filter assembly can be removed for cleaning.

[0052] It should be noted that, in this embodiment, as shown in Figure 2 and Figure 3 , the limiting groove 23 is an annular groove, and the part of the valve body 100 located on both sides of the base 20 is provided with a plug-in hole 160, which penetrates the valve body 100. The bottom end of the valve body 100 is further provided with an installation channel communicating with the filter cavity 120, and the filter screen 10 and the magnetic member 30 can enter the valve body 100 through the installation channel. The plug-in part 50 first passes through the plug-in hole 160, then enters the installation channel, cooperates with the limiting groove 23 in the installation channel, and finally extends out of the other end of the plug-in hole 160 to complete the installation. Since the limiting groove 23 is an annular groove, the plug-in part 50 does not need to be aligned after passing through the plug-in hole 160, but can be inserted into the limiting groove 23 to complete the fixation, saving time and effort. In addition, the plug-in part 50 can be selected as a U-shaped plug-in part, which includes two plug-in parts 51 connected by a connecting rod 52. The connecting rod 52 can make the two plug-in parts 51 inserted into the limiting groove 23 at the same time, and when disassembled, the two plug-in parts 51 can be pulled out at the same time through the connecting rod 52, which is simple and convenient to operate. It should be noted that the limiting groove 23 is located on the side of the sealing groove 22 away from the filter screen 10. This structure can effectively prevent liquid from leaking from the plug-in hole 160, thereby ensuring good sealing effect.

[0053] In addition, as shown in Figure 1 , Figure 4 and Figure 5 , the outer periphery of the base 20 is provided with a reverse buckle 24, which includes an extension part 241 and a reverse buckle part 242. One end of the extension part 241 is connected with the base 20, the other end extends away from the base 20 and is connected with the reverse buckle part 242, and the reverse buckle part 242 is bent towards the side of the limiting groove 23. After the plug-in part 50 is plugged into the valve body 100, the connecting part of the extension part 241 and the reverse buckle part 242 can abut against the bottom of the connecting rod 52, and the reverse buckle part 242 can abut against the outer side of the connecting rod 52, thereby ensuring that the plug-in part 50 cannot be separated from the valve body 100, and further ensuring good fixation effect of the filter assembly. In addition, when the base 20 has a tendency to rotate about the axis, the connecting rod 52 will give the reverse buckle 24 a reverse force and abut against the reverse buckle 24, thereby avoiding the rotation of the base 20 and ensuring the stability of the filter assembly, improving the filtering effect.

[0054] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, various obvious changes, re-adjustments and replacements can be made without departing from the protection scope of the present application.
