[0033] The present application is further described in detail below in conjunction with the accompanying drawings.

[0034] The embodiment of the present application discloses a quick-release filter check valve.

[0035] Reference Figure 1 The quick-release filter check valve comprises a valve body 1, a filter assembly 2 and a check assembly 3 are arranged on one side of the valve body 1, and the filter assembly 2 and the check assembly 3 are arranged in sequence along the water flow direction in the valve body 1. The filter assembly 2 is used to filter the water flow entering the valve body 1, and the check assembly 3 is used to prevent the water flow in the valve body 1 from flowing back. Quick-release connectors 4 are arranged at both ends of the valve body 1, and the quick-release connectors 4 are used to quickly release and install the pipes connected to the two ends of the valve body 1.

[0036] Reference Figure 1 and Figure 2 The filter assembly 2 includes a filter tube body 21 obliquely arranged on one side of the valve body 1, a cylindrical filter screen 22 is arranged in the filter tube body 21, a sealing cover 23 is arranged at one end of the filter tube body 21 away from the valve body 1, a mounting seat 24 is arranged between the inside of the valve body 1 and the filter tube body 21, one end of the cylindrical filter screen 22 abuts on the mounting seat 24, and the other end of the cylindrical filter screen 22 abuts on the sealing cover 23. A fixing structure 25 is detachably arranged between the sealing cover 23 and the filter tube body 21, and is fixed for detachable fixed connection between the sealing cover 23 and the filter tube body 21. The water flow in the valve body 1 is filtered through the cylindrical filter screen 22, and the impurities filtered out are located at the lower part of the filter tube body 21. The filtered water flow passes through the cylindrical filter screen 22 and enters the valve body 1 again to complete the filtration.

[0037] Reference Figure 2The fixing structure 25 includes a first annular mounting groove 251 provided on the side of the sealing cover 23 close to the filter tube body 21 and a second annular mounting groove 252 provided on the side of the filter tube body 21 close to the sealing cover 23. An annular magnet 253 is fixedly arranged in the second annular mounting groove 252, and an annular electromagnet 254 is fixedly arranged in the first annular mounting groove 251. The annular magnet 253 and the annular electromagnet 254 are arranged in cooperation with each other. When in use, the annular electromagnet 254 is energized to cooperate with the annular magnet 253, thereby realizing a fixed connection between the sealing cover 23 and the filter tube body 21; when the sealing cover 23 needs to be disassembled, the annular electromagnet 254 is de-energized, and the annular magnet 253 and the annular electromagnet 254 fall off from each other, thereby facilitating the disassembly of the sealing cover 23 from the filter tube body 21.

[0038] It should be noted that a sewage outlet is provided at the axial portion of the sealing cover 23, and a sewage outlet is threadedly connected with a sewage outlet bolt. The sewage outlet is opened by removing the sewage outlet bolt from the sealing cover 23, thereby realizing the discharge of sewage in the filter tube body 21, which is convenient for timely cleaning of the sewage in the filter tube body 21.

[0039] Reference Figure 1 and Figure 2 The check assembly 3 includes a limit seat 31 fixedly arranged in the valve body 1, the limit seat 31 is connected with the valve body 1, a mounting sleeve 32 is horizontally arranged on the side of the limit seat 31 away from the filter assembly 2, a rod body 33 is slidably connected in the mounting sleeve 32, a sealing block 34 is arranged at one end of the rod body 33 close to the filter assembly 2, a sealing ring 35 matching with the sealing block 34 is arranged on the limit seat 31, a reset structure 36 is arranged between the side of the sealing block 34 away from the filter assembly 2 and the limit seat 31, and the reset structure 36 is used to make the sealing block 34 abut against the sealing ring 35 to realize check when the water flow in the valve body 1 flows back. When the gate valve is used, when the water flow flows normally, the sealing block 34 is forced to drive the rod body 33 to slide in the mounting sleeve 32 to ensure the normal flow of the water flow; when the water flow is reversed, the reset assembly pushes the sealing block 34 and the sealing ring 35 to abut against each other to realize check of the water flow in the valve body 1.

[0040] It should be noted that the end of the limit seat 31 away from the filter assembly 2 is not solid. The figure shows that it is only a connection on the limit seat 31. A plurality of through holes are opened on it for the passage of water. When the compression spring 43 is compressed by the water flow, the sealing block 34 and the sealing ring 35 are separated, thereby allowing the water to flow through the check assembly 3, and vice versa, preventing the water from flowing back.

[0041] Reference Figure 2The reset structure 36 includes a reset spring 361 sleeved outside the mounting sleeve 32 , one end of the reset spring 361 is fixedly connected to the outer side of the mounting sleeve 32 , and the other end of the reset spring 361 is fixedly connected to the sealing block 34 .

[0042] Reference Figure 1 and Figure 3 Each quick-release connector 4 includes a plug-in pipe 41, which is inserted into one end of the valve body 1, and the outer wall of the plug-in pipe 41 abuts against the end of the valve body 1. A spring mounting seat 42 is provided on one side of the valve body 1 close to the plug-in pipe 41, and a compression spring 43 is fixedly connected between the spring mounting seat 42 and the plug-in pipe 41. A claw 44 is radially slidably arranged and penetrates the plug-in pipe 41. A receiving groove 45 for receiving the claw 44 is provided on the inner wall of the valve body 1, and the receiving groove 45 gradually narrows in the axial direction of the valve body 1 toward the outside.

[0043] Specifically, the plug-in pipe 41 is pressed to compress the compression spring 43, the pipe to be plugged 41 is plugged into the plug-in pipe 41, and the compression of the compression spring 43 is released, so that the compression spring 43 moves the plug-in pipe 41 away from the valve body 1, and then the inner wall of the valve body 1 abuts against one side of the claw 44, so that the claw 44 clamps the pipe to be plugged 41, and the pipe to be plugged 41 can be quickly installed. Similarly, the plug-in pipe 41 is pressed to compress the compression spring 43, and the pipe to be plugged 41 can be pulled out, which effectively improves the efficiency of the pipe installation process.

[0044] In other embodiments, an O-ring 46 may be provided between the end of the spring mounting seat 42 away from the plug-in pipe 41 and the valve body 1. The O-ring 46 effectively improves the sealing performance between the plug-in pipe 41 and the valve body 1.

[0045] The implementation principle of a quick-release filter check valve in the embodiment of the present application is as follows: water flows from the valve body 1 through the filter assembly 2 and the check assembly 3 in sequence. When the water flows through the filter assembly 2, it is filtered by the cylindrical filter screen 22, and when the water flows normally, the sealing block 34 is forced to drive the rod body 33 to slide in the installation sleeve 32 to ensure the normal flow of the water;

[0046] When the water flows backward, the return spring 361 pushes the sealing block 34 and the sealing ring 35 to abut against each other, thereby preventing the water flow in the valve body 1 from returning.

[0047] When the sealing cover 23 needs to be disassembled, the annular electromagnet 254 is powered off, the annular magnet 253 and the annular electromagnet 254 fall off from each other, and then the sealing cover 23 is disassembled from the filter tube body 21 .

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
