Description

Technical Field

[0001] This utility model relates to the field of filter valve technology, specifically a disc filter valve. Background Technology

[0002] With increasing awareness of water safety, filter valves, as core filtration devices in pipeline systems, are widely used in household water supply and as front-end water supply devices for some water appliances (such as solar water heaters, water heaters, washing machines, toilets, and electric water faucets). Traditional filter valves mostly use stainless steel filter screens or PP cotton filter cartridges as filtration media, but many technical defects have been exposed in actual use. Currently, mainstream products on the market, such as the stainless steel mesh filter structure disclosed in Chinese patent CN106052129A, achieve impurity interception through a cylindrical filter screen. The structure suffers from the following technical bottlenecks: First, the pores of the metal filter screen are prone to algae adhesion, forming a biofilm. Long-term use leads to pore shrinkage and water pressure reduction. However, brushing the metal filter screen can only clean its surface, making it difficult to clean the internal mesh. Second, the valve body itself does not have a switch. When cleaning the filter screen, the main valve needs to be closed repeatedly, causing interruptions to other equipment. Third, the metal mesh is prone to deformation during brushing, resulting in 20-40% of the gaps deforming, directly affecting the secondary filtration accuracy. Although there are detachable filter element structures in the existing technology, the disassembly and assembly process requires special tools. In addition, the patent with announcement number CN220328102U uses a threaded filter element, and tests show that the sealing ring between the filter screen and the support component has a sealing ineffectiveness after 50 disassembly and assembly cycles. Furthermore, traditional valve cores lack an independent inlet control module, requiring repeated operation of the main valve during maintenance, which is too cumbersome. Although the existing application number 202021433243.1 discloses a filter angle valve with a switch, the diameter of the switch valve plate installed in the middle of the inlet is limited due to design issues, affecting the water output. Based on the above technical shortcomings, there is an urgent need to develop a new filter valve structure that has independent flow control during cleaning and maintenance, and is faster and more convenient to clean, so as to achieve a dual breakthrough in filtration efficiency and ease of use. Utility Model Content

[0003] The purpose of this invention is to provide a disc filter valve to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a stacked disc filter valve, comprising a filter valve body, an inlet pipe on one side of the filter valve body, an outlet pipe on the top of the filter valve body, an inlet channel inside the filter valve body, a flow switch on the other side of the filter valve body, a cylindrical bracket installed at the bottom of the filter valve body, multiple openings on the outer wall of the cylindrical bracket, multiple filter discs inserted into the outer wall of the cylindrical bracket, stripes on the surface of the filter discs, a fixing nut screwed to the bottom of the cylindrical bracket, and a filter valve cup screwed to the bottom of the filter valve body.

[0005] Preferably, the flow switch includes a valve seat screwed to the inner wall of the other side of the filter valve body, a valve stem inserted into one side of the valve seat, a mounting bracket screwed to the outer wall of one side of the valve stem, a limit head fixed to one side of the mounting bracket, a first sealing gasket inserted into the outer wall of the limit head, and a rubber ring provided between the outer wall of the valve seat and the filter valve body.

[0006] Preferably, a second sealing gasket is inserted between the bottom end of the filter valve body and the filter valve cup body, and the second sealing gasket is R-shaped.

[0007] Preferably, a handwheel is installed on the outer wall of the valve stem, and the handwheel is screwed to the other side of the filter valve body.

[0008] Preferably, the outer wall of the handwheel is provided with anti-slip grooves.

[0009] Preferably, the outer walls of both the inlet and outlet pipes are provided with threads.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] By setting multiple filter discs, these striped filter discs are stacked together, and the stripes between the discs form filter pores of approximately 40μm-50μm, which can filter out large particles such as silt, red worms, rust, and algae from the water. For disassembly and cleaning, the water inlet is closed by turning off the water flow switch, preventing water from continuing to enter the filter valve cup. Then, the filter valve cup is removed by rotating it, and the fixing nut is unscrewed to remove the filter discs for cleaning. Because the filter discs can be separated, brushing is more convenient and allows for thorough cleaning of even the crevices. Closing the water inlet further facilitates disassembly. Washing the filter discs eliminates the hassle of repeatedly shutting off the main valve when disassembling and cleaning them. The filter discs are easy to disassemble without the need for special tools. Furthermore, since the filter discs are stacked one on top of another, water will not flow directly into the cylindrical bracket without being filtered. In addition, stainless steel filter screens are prone to deformation during brushing, causing 20-40% of the gaps to deform, which directly affects the secondary filtration accuracy. However, the filter discs will not deform during brushing. Even after multiple brushings, they can still effectively separate fine particles and maintain high-efficiency secondary filtration performance. Moreover, the water flow switch does not affect the water output when it is not turned off. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] With increasing awareness of water safety, filter valves, as core filtration devices in pipeline systems, are widely used in household water supply and as front-end water supply devices for some water appliances (such as solar water heaters, water heaters, washing machines, toilets, and electric water faucets). Traditional filter valves mostly use stainless steel filter screens or PP cotton filter cartridges as filtration media, but in actual use, they have revealed many technical defects. This utility model provides a stacked disc filter valve, designed to prevent fish gills. This design consists of 10 striped filter discs stacked together, with the stripes between the discs forming filter pores of approximately 40μm-50μm, which can filter out large particles such as sediment, red worms, rust, and algae in the water. The filter valve body 1 has a switch that can close the water inlet, making it easier to disassemble and clean the filter cartridge, saving the trouble of repeatedly closing the main valve when disassembling and cleaning the filter cartridge. Moreover, stainless steel filter screens are prone to deformation of the filter wires during washing, causing 20-40% of the gaps to deform, directly affecting the accuracy of secondary filtration.

[0019] like Figures 1-4 As shown, this utility model provides a technical solution: a stacked disc filter valve, including a filter valve body 1, an inlet 2 on one side of the filter valve body 1, an outlet 5 at the top of the filter valve body 1, an inlet channel 6 inside the filter valve body 1, a flow switch 3 on the other side of the filter valve body 1, a cylindrical bracket 8 installed at the bottom of the filter valve body 1, multiple openings 9 on the outer wall of the cylindrical bracket 8, multiple filter discs 10 inserted into the outer wall of the cylindrical bracket 8, the surface of the filter discs 10 being striped, a fixing nut 12 screwed to the bottom of the cylindrical bracket 8, and a filter valve cup 4 screwed to the bottom of the filter valve body 1. Water flows into the filter valve cup 4 through the inlet channel 6 and is filtered by the filter discs 10. The filtered water is discharged through the outlet 5, and the water flow direction is as follows. Figure 3 The direction of the arrow shown.

[0020] It is important to note that by setting multiple filter discs 10, with each striped filter disc 10 stacked together, the stripes between the discs form filter pores of approximately 40μm-50μm, which can filter out large particles such as silt, red worms, rust, and algae in the water. When disassembling and cleaning, the water inlet channel 6 can be closed by turning off the water flow switch 3, so that water will not continue to enter the filter valve cup 4. Then, the filter valve cup 4 can be removed by rotating it, and the fixing nut 12 can be rotated off to remove the filter discs 10 for cleaning. Closing the water inlet makes it easier to disassemble and clean the filter discs 10, saving the trouble of repeatedly closing the main valve when disassembling and cleaning the filter discs 10. The filter discs 10 are easy to disassemble and do not require special tools. In addition, stainless steel filter screens are prone to deformation of the filter wires during brushing, resulting in deformation of 20-40% of the gaps, which directly affects the secondary filtration accuracy. However, the filter discs 10 will not deform during brushing, thus avoiding affecting subsequent filtration.

[0021] like Figure 3 and Figure 4 As shown, the flow switch 3 includes a valve seat 302 screwed to the inner wall of the other side of the filter valve body 1. A valve stem 301 is inserted into one side of the valve seat 302. A mounting bracket 303 is screwed to the outer wall of one side of the valve stem 301. A limit head 304 is fixed to one side of the mounting bracket 303. A first sealing gasket 305 is inserted into the outer wall of the limit head 304. A rubber ring 306 is provided between the outer wall of the valve seat 302 and the filter valve body 1. A second sealing gasket 7 is inserted between the bottom end of the filter valve body 1 and the filter valve cup body 4. The second sealing gasket 7 is R-shaped. A handwheel 11 is installed on the outer wall of the valve stem 301. The handwheel 11 is screwed to the other side of the filter valve body 1. The outer wall of the handwheel 11 is provided with anti-slip grooves. The outer walls of the water inlet 2 and the water outlet 5 are both provided with threads. By rotating the handwheel 11, the handwheel 11 is connected to the valve stem 301, which drives the valve stem 301 to move forward, thereby driving the mounting bracket 303, the limit head 304 and the first sealing gasket 305 to move forward. In this way, the first sealing gasket 305 can block the water inlet channel 6.

[0022] It is important to note that the second sealing gasket 7 ensures a tight fit between the filter valve body 1 and the filter valve cup 4, preventing water leakage. The curved design of the R-type second sealing gasket 7 allows it to better fit the mating surface. When subjected to pressure or external force, the R-type second sealing gasket 7 can deform and tightly press against the connecting surface, forming a better sealing effect and preventing leakage. Turning the handwheel 11 can close the water flow switch 3, which closes the water inlet channel 6. The outer wall of the handwheel 11 has anti-slip grooves for user convenience and to prevent slipping. In addition, the outer walls of the water inlet 2 and the water outlet 5 are threaded to facilitate the installation of pipes on the water inlet 2 and the water outlet 5.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
