Description

Technical Field

[0001] This utility model belongs to the technical field of filtration devices, and relates to a magnetic filter, particularly a vertical magnetic filter. Background Technology

[0002] Currently available magnetic filters lack flexibility and cannot adjust the installation direction of the inlet and outlet water ends according to different installation conditions; in addition, the performance of these magnetic filters lacks stability, affecting their use. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a straight magnetic filter with more stable performance and more flexible installation.

[0004] The objective of this utility model can be achieved through the following technical solution: A straight magnetic filter, comprising a valve body and a water pipe with inlet and outlet ends, characterized in that the water pipe has a union end connected to the valve body, the union end is threaded with a union sleeve, the valve body has a cleaning and drain end, the cleaning and drain end has a cleaning and drain port communicating with the interior of the valve body, a switch end extends perpendicularly to the peripheral wall of the cleaning and drain end, the switch end has an opening and closing valve assembly that provides opening and closing function, the switch end has an injection molded part with knurled outer wall, and the injection molded part has an internal adjusting thread.

[0005] In the aforementioned straight magnetic filter, the on / off valve assembly includes a screw that engages with an internal adjusting thread, a tapered plug at the front end of the screw, a handwheel at the end of the screw, a valve port for the plug to enter and exit the cleaning and draining end, and a sealing ring between the screw and the inner wall of the cleaning and draining end.

[0006] In the aforementioned vertical magnetic filter, a plug is connected to the cleaning and draining end.

[0007] Compared with existing technologies, this vertical magnetic filter has the advantages of flexible installation and improved performance. Attached Figure Description

[0011] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0012] like Figure 1 , Figure 2 As shown, this vertical magnetic filter includes a valve body 1 and a water pipe 2 with inlet and outlet ends. The water pipe has a union end 3 that connects to the valve body 1. A union sleeve 4 is threaded onto the union end 3, making the installation and removal of the water pipe 2 more convenient. It can be rotated and positioned in any direction according to installation requirements. The valve body 1 has a cleaning and drain end 5, with a cleaning and drain port 6 communicating with the interior of the valve body 1. A switch end 7 extends perpendicularly from the periphery of the cleaning and drain end 5. The switch end 7 contains an on / off valve assembly 8 that provides opening and closing function. An injection-molded part 10 with knurled outer walls 9 is injection-molded inside the switch end 7. The injection molded part 10 has an internal adjusting thread 11. During the injection molding process, the injection molded part 10 with a roller is provided to position it against the inner wall of the switch end 7. The inner wall of the switch end 7 can be formed with a meshing protrusion that engages with the knurling 9, and then integrally injection molded. In addition, the internal adjusting thread 11 is provided to connect with the on / off valve assembly 8. By rotating the on / off valve assembly 8 in both directions, the cleaning drain port 6 can be opened and closed. Cleaning fluid can be poured into the cleaning drain port 6, and water can be flushed through the water inlet to flush the internal space of the valve body 1, including the filter screen. In addition, the on / off valve assembly 8 is a side-operated switch structure, which is unobstructed in operation.

[0013] To elaborate further, the valve assembly 8 includes a screw 12 that mates with the internal adjusting thread 11. The front end of the screw 12 has a tapered plug 13, and the end of the screw 12 has a handwheel 17. The cleaning and drain end 5 has a valve port 14 for the plug 13 to enter and exit. The valve port 14 has a tapered groove structure. There is a sealing ring 15 between the screw 12 and the inner wall of the cleaning and drain end 5. By screwing in the screw 12, the plug 13 is screwed into the valve port 14, thereby blocking the cleaning and drain port 6. The inside of the valve body 1 is not connected to the port of the cleaning and drain end 5, which achieves a plug sealing effect and improves performance stability. When cleaning is required, the screw 12 is screwed out in the opposite direction to open the cleaning and drain port 6.

[0014] Preferably, a plug cap 16 is connected to the cleaning and sewage discharge end 5.

[0015] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0016] Although this document frequently uses terms such as valve body 1, water pipe 2, union end 3, union sleeve 4, cleaning and drain end 5, cleaning and drain port 6, switch end 7, on / off valve assembly 8, knurled 9, injection molded part 10, internal adjusting thread 11, screw 12, plug 13, valve port 14, sealing ring 15, plug cap 16, and handwheel 17, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
