Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a valve with a filtering function. Background Art

[0002] When a fluid pipeline is used to transport fluid, solid impurities or harmful particles carried in the fluid often cause the pipeline to become clogged or transported to the living environment, endangering human health. Therefore, filter media are often added to the valve pipeline to filter the fluid. In the prior art, the filter media for valve filtration include filter screens, filter cloths, filter elements, etc., which can filter out impurities such as particulate matter and suspended matter in the fluid. However, since the filter media is generally located in the pipeline, it is difficult to replace it quickly, and because of its small filtration area, its service life is also short.

[0003] The patent name that has been published is a Chinese utility model patent with the publication number CN220286560U, which includes a valve body, an arc groove, an arc filter, an adjustment clamping assembly, an arc plate and an arc plate 2. Two symmetrically distributed arc grooves are provided on the valve body, and the arc grooves are used to fix the arc filter. The adjustment arc plate is arranged on the inner side of the arc groove, and the arc plate can be slid out from the inner side of the arc groove by adjusting the clamping assembly. The sliding out of the arc plate drives the arc filter to move, thereby realizing the cleaning of the arc filter and the cleaning between the arc filters. The arc filter and the arc plate 2 are detachably connected. The arc plate 2 is connected to the outer side of the arc groove, and the arc filter can be easily removed from the arc plate 2. The utility model has the advantages of convenient installation and disassembly, good filtering effect, and easy cleaning and maintenance.

[0004] However, the space between the filters is small, making it difficult to store more impurities, and they need to be replaced frequently. In addition, the impurities on the first layer of arc-shaped filters will be deposited in the valve structure and will not move out of the valve structure with the filters. After a long time, the valve will be blocked. Utility Model Content

[0005] The purpose of the present application is to provide a valve with a filtering function, which solves the technical problems of multiple filtering of impurities in the valve pipeline and rapid replacement of the filtering medium.

[0006] In order to solve the above technical problems, the solution adopted by this application is as follows:

[0028] Example

[0029] Please refer to Figure 1-Figure 4 The utility model provides a valve with filtering function, including a fluid pipeline 1, a filter cartridge 2, an adsorbent 3, a valve body 11, a first filtering chamber 12, a second filtering chamber 13, a stopper 14, and a brushing structure.

[0030] Furthermore, two valve bodies 11 are fixedly arranged on the fluid pipeline 1, and adjacent first filter chambers 12 and second filter chambers 13 are fixedly arranged on the fluid pipeline 1. The first filter chamber 12 and the second filter chamber 13 are located between the two valve bodies 11. When the two valve bodies 11 block the fluid pipeline 1, the pipeline between the two valve bodies 11 forms a separate pipeline chamber, so that no fluid continues to enter the first filter chamber 12 and the second filter chamber 13 in the pipeline chamber.

[0031] Preferably, filter components are placed in the first filter chamber 12 and the second filter chamber 13. After the pipeline chamber is isolated from the fluid, the filter components can be quickly removed from the first filter chamber 12 and the second filter chamber 13 and replaced manually without disassembling the fluid pipeline 1 and affecting the pipeline circulation.

[0032] Furthermore, the filter assembly is configured as a filter cartridge 2, an adsorbent 3, and a scrubbing structure.

[0033] The first filter chamber 12 is connected to the inner channel of the fluid pipeline 1. A filter cartridge 2 is arranged in the first filter chamber 12. The filter cartridge 2 is hollow. One end of the filter cartridge 2 is not sealed and serves as the inlet of the filter cartridge 2. The cavity wall of the filter cartridge 2 has a plurality of filter holes extending therethrough from top to bottom, serving as the outlet of the filter cartridge 2. A stopper 14 is fixedly arranged in the fluid pipeline 1. The filter cartridge 2 abuts against the stopper 14, and the fluid pipeline 1 is divided into left and right pipelines. The fluid in the fluid pipeline 1 can only enter the pipeline at the other end through the filter holes of the filter cartridge 2.

[0034] Preferably, the inlet of the filter cartridge 2 faces the fluid inlet end in the fluid pipeline 1, and the fluid enters the cavity of the filter cartridge 2 and flows into the pipeline at the other end from the filter holes, while the large particle impurities entrained in the fluid are blocked by the filter holes and retained in the cavity of the filter cartridge 2.

[0035] The second filter chamber 13 is connected to the inner channel of the fluid pipeline 1. An adsorbent 3 is arranged in the second filter chamber 13. A stopper 14 is fixedly arranged in the fluid pipeline 1. The adsorbent 3 abuts against the stopper 14 to separate the fluid pipeline 1 into left and right pipelines. The fluid flows into the adsorbent 3 after passing through the filter cartridge 2. The fluid can only enter the pipeline at the other end through the adsorbent 3.

[0036] Preferably, the fluid filtered by the filter cartridge 2 to obtain large particles of impurities enters the adsorbent 3 through the fluid pipe 1. The adsorbent 3 is made of filter cotton as a whole. When the fluid passes through the adsorbent 3, the mud and particles carried in the fluid will continue to be adsorbed to reduce odor.

[0037] Furthermore, a brushing structure is slidably provided on the cavity wall of the filter cartridge 2 , and the brushing structure includes a pumping rod 21 , a scraper 22 , a baffle 23 , a baffle sheet 24 , and bristles 25 .

[0038] The pumping rod 21 passes through the first filter chamber 12 and the tube wall of the filter cartridge 2, and extends into the cavity of the filter cartridge 2. The pumping rod 21 is coaxial with the filter cartridge 2. A circular scraper 22 matching the cross-sectional shape of the filter cartridge is fixedly installed at the end of the pumping rod 21 extending into the interior of the filter cartridge 2. A plurality of bristles 25 are fixedly installed on the circular outer wall of the scraper 22. The bristles 25 are circumferentially distributed on the circular outer wall of the scraper 22, and the ends of the bristles 25 are in contact with the cavity wall of the filter cartridge 2.

[0039] Preferably, when the pull rod 21 is manually pulled, the pull rod 21 drives the scraper 22 to slide in the cavity wall of the filter cartridge 2, so that the bristles 25 brush the cavity wall of the filter cartridge 2, peeling off impurities attached to the cavity wall, avoiding excessive accumulation of impurities in the cavity of the filter cartridge 2, and the impurities covering the through filter holes on the filter cartridge 2, causing pipeline blockage.

[0040] The scraper 22 is provided with a plurality of through holes, and a fixed shaft is provided in the through hole, and the fixed shaft is rotatably connected to one side of the baffle 23. When the baffle is coplanar with the scraper, the baffle blocks the through hole, and a baffle 24 is fixedly installed on the top of the through hole, and the baffle 24 is located above the baffle 23. By providing the fixed shaft, the baffle can be rotated relative to the scraper, thereby exposing or blocking the through hole; by providing the baffle, the rotation direction of the baffle is limited, so that it can only rotate toward the bottom of the scraper.

[0041] Preferably, in the process of brushing the filter cartridge 2 by the brushing structure, when the scraper 22 moves toward the top of the filter cartridge 2, the baffle 23 is affected by the fluid in the filter cartridge 2 and its own gravity and swings downward, and the through hole on the scraper 22 is not blocked by the baffle 23, so that the fluid is easy to flow, thereby preventing the fluid in the fluid pipeline 1 from being squeezed when the scraper 22 moves; when the scraper 22 moves toward the bottom of the filter cartridge 2, the baffle 23 is affected by the fluid in the bottom chamber of the filter cartridge 2 and the filtered impurities and swings upward, and the baffle 23 is blocked by the baffle 24 at the top of the through hole when it swings, so that the baffle 23 blocks the through hole, thereby preventing the impurities settled at the bottom of the filter cartridge 2 from entering the fluid pipeline 1 again when the scraper 22 moves.

[0042] When the scrubbing structure is stationary, the baffle 23 keeps swinging downward, so that the through hole is in a normally open state, which facilitates the fluid to pass through the filter cartridge 2.

[0043] In some embodiments, the valve body 11 includes a valve stem assembly 111 and a valve body partition 112 , and the valve stem assembly 111 and the valve body partition 112 are used to achieve valve blocking through existing technologies.

[0044] The valve body partition 112 is fixedly arranged in the fluid pipeline 1, and limits the fluid flow through a single channel. The valve stem assembly 111 rises and falls in the flow pipeline 1 to block and allow flow through the single channel on the valve body partition 112, thereby realizing the valve function of the valve body 11.

[0045] In some embodiments, the first filter chamber 12 includes a first sealing plate 121, the second filter chamber 13 includes a second sealing plate 131, and the adsorbent 3 includes a fixing rod 31.

[0046] The bottom of the first filter chamber 12 includes a first sealing plate 121 that can be removed by threading. By opening the first sealing plate 121, the filter cartridge 2 can be taken out from the first filter chamber 12, and a sealing gasket is provided at the threaded connection of the first sealing plate 121; the bottom of the second filter chamber 13 includes a second sealing plate 131 that can be removed by threading, and a fixing rod 31 is fixedly installed on the second sealing plate 131, and the fixing rod 31 is used to support the filter cotton in the adsorbent 3. By opening the second sealing plate 131, the adsorbent 3 can be taken out from the second filter chamber 13.

[0047] Please refer to Figure 5The utility model provides a valve with a filtering function, which also includes a first observation plate 41 and a second observation plate 42.

[0048] The first observation plate 41 is fixedly mounted on the wall of the first filter chamber 12 and penetrates the chamber wall of the first filter chamber 12. The first observation plate 41 is a transparent plastic plate. The second observation plate 42 is fixedly mounted on the wall of the second filter chamber 13 and penetrates the chamber wall of the second filter chamber 13. The second observation plate 42 is a transparent plastic plate.

[0049] Preferably, the staff can see the filter cartridge 2 inside the first filter chamber 12 and the adsorbent 3 inside the second filter chamber 13 with the naked eye, which is convenient for observing the blockage of the filter holes on the filter cartridge 2 and the adsorption of the filter cotton on the adsorbent 3, and is convenient for timely cleaning of impurities and replacement of components.
