Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a valve with a filtering function. Background Technology

[0002] A valve with a filter function is a device that integrates a valve and a filter into one unit. It can both cut off or regulate the medium in the pipeline and filter out solid particles in the medium at the same time, protecting downstream equipment.

[0003] Existing valves with filtration functions, such as the reservoir drainage valve with filtration function for water conservancy projects (publication number CN213018062U), include a valve body with a metal water pipe fixedly connected inside. A rotating rod is movably connected to the upper end of the valve body, with a rotating handle fixedly connected to the top of the rod. A valve plate is fixedly connected to the bottom of the rod. The valve body has a hollow structure with a collection net inside the middle section. An activated carbon filter layer is fixedly connected to the right side of the collection net, and a filter sand layer is connected to the right side of the activated carbon filter layer. Sealing rings surround the collection net, activated carbon filter layer, and filter sand layer. While these valves offer some filtration, their flip-top cover and rotating shaft design do not meet the valve's sealing requirements, making it impossible to guarantee a tight seal during actual use and preventing stable operation under high water pressure. Therefore, a valve with filtration function needs to be designed to address these issues. Utility Model Content

[0034] Working principle: During operation, Figure 1 The left end of the filter pipe 2 and the right end of the valve body 1 are respectively connected and fixed to the conveying pipe. The water flows from left to right, and the water first passes through... Figure 2 The filter screen 505 on the left side enters the first filled filter material 506, then passes through the filter screen 505 on the right side and contacts the filter block 503, then passes through the left end of the second filter cylinder 601, enters the second filter cylinder 601 and contacts the second filled filter material 602, and finally flows out from the second filter cylinder 601 into the valve body 1.

[0035] During disassembly and cleaning, simply remove the filter tube 2. First, remove the positioning rubber ring 507 from the left end. Then, use a small hook to hook the filter screen 505 at the left end and remove the first filter cylinder 504 and the connecting seat ring 501 as a whole for cleaning or replacement. Next, insert the end of a flat tool, such as a flathead screwdriver, into the operating groove 604 and unscrew the second filter cylinder 601 out of the connecting groove 4. Clean or replace the second filter cylinder 601. Finally, reinstall the first filter cylinder 504, the positioning rubber ring 507, and the second filter cylinder 601 in sequence. Connect the filter tube 2 to the valve body 1 and the conveying pipeline in sequence. The entire device can then be used again. This is the working principle of the valve with filtration function.
