Description

Technical Field

[0001] This application relates to the field of butterfly valve technology, and more specifically, to an anti-clogging sealing butterfly valve. Background Technology

[0002] A butterfly valve, also known as a flap valve, is a simple regulating valve used for on / off control of low-pressure pipeline media. A butterfly valve is characterized by a disc-shaped closing element (valve disc or butterfly plate) that rotates around a valve shaft to open and close. Butterfly valves can control the flow of various types of fluids, including air, water, steam, various corrosive media, mud, oil, liquid metals, and radioactive media. They primarily function as shut-off and throttling devices in pipelines. The butterfly valve's opening and closing element is a disc-shaped butterfly plate that rotates around its own axis within the valve body to achieve opening, closing, or regulation. Butterfly valves are widely used not only in general industries such as petroleum, gas, chemical, and water treatment, but also in cooling water systems of thermal power plants.

[0003] Currently, when using electric flange butterfly valves, the fluid in the pipeline may contain impurities, which may accumulate inside the flange butterfly valve device, causing valve blockage. At present, most of them rely on filters to prevent blockage, which is inconvenient to clean and replace. In addition, current electric flange butterfly valves do not have a reserved storage space for impurities, and the filtered impurities will still remain inside the butterfly valve, making it difficult to clean.

[0004] To address the aforementioned issues, this application provides an anti-clogging sealing butterfly valve. Utility Model Content

[0005] The anti-clogging sealing butterfly valve provided in this application adopts the following technical solution:

[0011] Furthermore, a scraper is fixedly connected to the outer side of the rotating block, and the scraper is attached to the upper end of the first filter plate.

[0012] With the above technical solution, the scraper is used to rotate at the upper end of the first filter screen plate, that is, the scraper is used to scrape off the impurities attached to the upper end of the first filter screen plate.

[0013] Furthermore, a collection chamber is provided at the upper end of the base plate, and a second filter screen is fixedly connected through the inner side wall of the collection chamber. A circular groove is provided at the upper end of the base plate, and a limiting groove is provided at the bottom wall of the circular groove. A second locking block is fixedly connected to the outer surface of the base plate.

[0014] Through the above technical solution, the collection chamber is used to temporarily store impurities and prevent them from entering the interior of the butterfly valve body, while the second filter screen facilitates the free passage of liquid.

[0015] Furthermore, the bottom plate is attached to the lower end of the top plate, the second locking block is slidably engaged with the second locking groove, the round rod passes through the interior of the round groove, and the baffle is rotatably engaged with the limiting groove.

[0016] Through the above technical solution, the second locking block is used to limit the bottom plate and prevent the bottom plate from rotating inside the inlet pipe, and the limiting groove is used to limit the baffle, that is, to prevent the round rod from leaving the round groove.

[0017] In summary, this application includes the following beneficial technical effects:

[0018] This application can filter the liquid flowing into the butterfly valve body to prevent impurities from clogging the butterfly valve body, and can temporarily store the filtered impurities so that the filtered impurities will not affect the subsequent filtration effect. The impurities attached to the first filter screen are scraped off by the scraper and pushed into the inside of the collection chamber, thereby temporarily storing the impurities.

[0029] Example:

[0030] This application discloses an anti-clogging sealing butterfly valve. Please refer to [link / reference]. Figures 1-5The valve includes a butterfly valve body 1, with an inlet pipe 2 fixedly connected to the upper end of the butterfly valve body 1. An adjustment component 3 is provided inside the inlet pipe 2. A first slot 21 and a second slot 22 are provided on the inner wall of the inlet pipe 2. A threaded groove 211 is provided on the bottom wall of the first slot 21. The adjustment component 3 includes a top plate 31 and a bottom plate 33 provided inside the inlet pipe 2. A micro motor is provided inside the upper end of the top plate 31. A rotating block 32 is fixedly connected to the output end of the micro motor.

[0031] The top plate 31 has a first filter plate 312 fixedly connected to the upper end, a round rod 311 fixedly connected to the lower end of the top plate 31, a baffle 3111 fixedly connected to the lower end of the round rod 311, and a first locking block 313 fixedly connected to the outer side of the top plate 31. The upper end of the first locking block 313 has a through groove 3131.

[0032] The first filter plate 312 facilitates the filtration of impurities in the liquid, and the baffle 3111 is used to limit the round rod 311 to prevent the round rod 311 from leaving the interior of the round groove 333.

[0033] The first card block 313 is slidably engaged with the first card slot 21, and the through slot 3131 is connected to the second card slot 22.

[0034] The first locking block 313 is used to limit the top plate 31 to prevent the top plate 31 from rotating inside the inlet pipe 2.

[0035] A scraper 321 is fixedly connected to the outside of the rotating block 32, and the scraper 321 is attached to the upper end of the first filter plate 312.

[0036] The scraper 321 is used to rotate at the upper end of the first filter plate 312, that is, the scraper 321 is used to scrape off the impurities attached to the upper end of the first filter plate 312.

[0037] A collection chamber 331 is provided at the upper end of the base plate 33. A second filter screen 332 is fixedly connected through the inner side wall of the collection chamber 331. A circular groove 333 is provided at the upper end of the base plate 33. A limiting groove 3331 is provided on the bottom wall of the circular groove 333. A second locking block 334 is fixedly connected on the outer surface of the base plate 33.

[0038] The collection chamber 331 is used to temporarily store impurities and prevent them from entering the interior of the butterfly valve body 1. The second filter screen 332 facilitates the free passage of liquid.

[0039] The bottom plate 33 is attached to the lower end of the top plate 31, the second locking block 334 is slidably engaged with the second locking groove 22, the round rod 311 passes through the inside of the round groove 333, and the baffle 3111 is rotatably engaged with the limiting groove 3331.

[0040] The second locking block 334 is used to limit the bottom plate 33 to prevent the bottom plate 33 from rotating inside the inlet pipe 2. The limiting groove 3331 is used to limit the baffle 3111, that is, to prevent the round rod 311 from disengaging from the round groove 333.

[0041] The implementation principle of this embodiment is as follows: When the liquid enters the butterfly valve body 1 through the inlet pipe 2, the liquid will flow downward through the first filter plate 312 and the second filter 332 respectively. The impurities on the side of the second filter 332 will accumulate inside the collection chamber 331, and the impurities on the upper end of the first filter plate 312 will accumulate on the upper end of the first filter plate 312. Then, the micro motor inside the top plate 31 drives the scraper 321 to rotate on the upper end of the first filter plate 312, thereby pushing the impurities attached to the upper end of the first filter plate 312 into the collection chamber 331.

[0042] When it is necessary to process the impurities collected inside the collection chamber 331, the top plate 31 is pulled to move the first locking block 313 upward along the first locking groove 21. At this time, under the action of the round rod 311, the top plate 31 can simultaneously move the bottom plate 33 upward along the second locking groove 22 until the bottom plate 33 is disengaged from the inlet pipe 2. At this time, the impurities temporarily stored inside the collection chamber 331 can be processed.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
