Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a concentrated water reuse proportional valve. Background Art

[0002] The concentrated water reuse proportional valve is an important component applied in water treatment equipment, especially at the concentrated water discharge port of a high-pressure reverse osmosis membrane device. Its main function is to control the mixing ratio of concentrated water and raw water according to the water quality of the effluent when the concentrated water generated by a direct drinking water device flows back to the raw water pipeline, thereby reducing the waste water rate.

[0003] After the existing concentrated water reuse proportional valve is used for a period of time, impurities in the water will adhere to the valve wall to form dirt, and the uneven distribution of the dirt will cause the valve core to be subjected to irregular resistance during the movement process, thereby affecting the movement accuracy of the valve core. This may cause the concentrated water reuse proportional valve to be unable to accurately control the flow rate and affect the mixing ratio. At the same time, the friction between the dirt particles and the valve wall will exacerbate the wear of the components and shorten the service life of the moving mechanism. Therefore, it is necessary to provide a concentrated water reuse proportional valve that can timely discharge impurities to ensure the accurate mixing ratio and the service life of the mechanism.

[0036] Please refer to Figures 1-6 As shown, this embodiment is a concentrated water reuse proportional valve, including:

[0037] A valve body assembly, which includes a valve seat 101, a valve cavity 102, a valve core 103, a receiving rod 104 and an electromagnetic control component 105;

[0038] Cleaning assembly, the cleaning assembly includes an elastic scraper 201 and a through hole 202;

[0039] A valve seat 101 has a valve cavity 102 formed inside it. A valve core 103 is movably connected to the middle of the valve cavity 102. A connecting rod 104 is fixedly connected between the valve cores 103. An electromagnetic control component 105 is fixedly installed at the left end of the valve seat 101. The electromagnetic control component 105 is connected to the connecting rod 104. Elastic scrapers 201 are movably connected to both sides of the valve core 103. A through hole 202 is formed in the middle of the elastic scraper 201, and the connecting rod 104 is inserted through the middle of the through hole 202;

[0040] The electromagnetic control component 105 controls the movement of the connecting rod 104 through electromagnetism, and then drives the movement of the valve core 103 to achieve the controlled mixing of concentrated water and raw water. The elastic scraper 201 can move along with the valve core 103 to clean the dirt adhering to the inner wall of the valve cavity 102;

[0041] The cross-sectional area of the elastic scraper 201 is larger than the cross-sectional area of the valve core 103;

[0042] The size setting of the cross-sectional areas between the above-mentioned elastic scraper 201 and the valve core 103 can ensure that the elastic scraper 201 completely fits the valve cavity 102, thus ensuring the cleaning effect;

[0043] The valve body assembly further includes a water outlet cavity 106 and a water outlet pipe 107;

[0044] The lower part of the valve core 103 is provided with a water outlet cavity 106. The water outlet cavity 106 communicates with the valve cavity 102. A water outlet pipe 107 is provided at the bottom of the water outlet cavity 106;

[0045] The provision of the water outlet cavity 106 and the water outlet pipe 107 ensures the discharge of water flow;

[0046] The valve core 103 is generally in the shape of a cube, and the length and width of the valve core 103 are both larger than the diameter of the water outlet cavity 106;

[0047] The size setting between the valve core 103 and the water outlet cavity 106 can ensure that the valve core 103 completely covers the water outlet cavity 106;

[0048] The cleaning assembly further includes a threaded hole 203, a mounting hole 204 and a wing screw 205;

[0049] Threaded holes 203 are formed on both sides of the valve core 103. Mounting holes 204 are formed on the elastic scraper 201, and wing screws 205 are inserted between the mounting holes 204 and the threaded holes 203;

[0050] The cooperation of the above components can achieve the installation and disassembly of the elastic scraper 201, and thus facilitate the replacement of the elastic scraper 201;

[0051] It further includes an adsorption assembly;

[0052] The adsorption assembly includes an activated carbon adsorption mesh plate 301 and fixing screws 302;

[0053] The bottom end of the water outlet pipe 107 is provided with an activated carbon adsorption mesh plate 301, and the activated carbon adsorption mesh plate 301 is connected to the water outlet pipe 107 through fixing screws 302;

[0054] The setting of the activated carbon adsorption mesh plate 301 can adsorb the impurities and dirt scraped off by the elastic scraper 201, and can also improve the water quality;

[0055] Working principle: Water flow is introduced into the valve cavity 102 through the water inlet pipe. The electromagnetic control component 105 drives the receiving rod 104 and the valve core 103 to move. At this time, a gap is formed between the valve core 103 and the water outlet cavity 106, and the water flow flows out through the water outlet pipe 107 from the gap. The valve core 103 will drive the elastic scraper 201 to move on the inner wall of the valve cavity 102 to scrape off the attached dirt, and under the action of the water flow, it flows into the water outlet pipe 107. Subsequently, the activated carbon adsorption mesh plate 301 at the bottom of the water outlet pipe 107 adsorbs. When the elastic scraper 201 needs to be replaced, the valve seat 101 is disassembled, the butterfly screw 205 is taken out from the mounting hole 204 and the threaded hole 203, and then the new elastic scraper 201 is installed;

[0056] This step can timely clean the impurities and dirt adhered inside the valve cavity, thereby avoiding irregular resistance during the movement of the valve core, ensuring the movement accuracy of the valve core, and then realizing accurate flow control, ensuring accurate mixing ratio, and at the same time avoiding violent friction between the valve core and the valve wall, and ensuring the service life of the moving mechanism.
