All-metal rail-mounted high-sealing butterfly valve

Abstract

This utility model relates to an all-metal track-type high-sealing butterfly valve, belonging to the field of butterfly valve technology. It includes a valve body with an upper and lower rotating shaft inside. A butterfly plate is fixedly connected to the lower end of the upper rotating shaft, and a positioning shaft is fixedly connected inside the butterfly plate. A cleaning component and a dispersing component are rotatably connected to the side surface of the positioning shaft. By incorporating the cleaning component, the impact force generated by airflow or liquid flow drives the scraper to rotate. During the rotation of the scraper, dirt on the butterfly plate is scraped off, enabling the butterfly valve to automatically clean dirt from the butterfly plate during use, improving the cleanliness of the butterfly plate, thereby reducing the frequency of butterfly valve maintenance and lowering maintenance costs. Simultaneously, the dispersing component works in conjunction with the cleaning component to disperse the dirt scraped off by the scraper, resulting in less residue in the fluid and preventing it from flowing into the next process and causing accumulation and blockage, further improving the cleaning effect.

Description

Technical Field

[0001] This utility model relates to the field of butterfly valve technology, and specifically to an all-metal track-type high-sealing butterfly valve. Background Technology

[0002] A butterfly valve is a type of valve used to control fluid flow and is widely used in piping systems in industrial and civil applications.

[0003] According to the public announcement (CN213776407U), an aluminum alloy wafer-type butterfly valve is disclosed. This technology discloses that the valve includes a valve body, a butterfly plate, a valve stem, an upper valve seat, and a lower valve seat; the upper and lower valve seats are respectively installed at the top and bottom of the valve body; the valve stem is fixedly passed through the butterfly plate, and the excess portion is rotatably connected to the upper and lower valve seats respectively; the upper valve seat has an anti-flying groove inside, and the convex shaft on the valve stem engages with the anti-flying groove. The valve body of this aluminum alloy wafer-type butterfly valve is made of high-pressure standard aluminum alloy die-casting, and the anti-flying design between the valve stem and the upper valve seat greatly improves the pressure-bearing capacity of the butterfly valve, making it less prone to deformation in actual use and improving sealing performance.

[0004] However, although this technical solution has high sealing performance and pressure resistance, which makes the butterfly valve unable to be opened frequently, under long-term use, a lot of dirt is very easy to stick or accumulate on the butterfly plate and cannot be cleaned, thus reducing the butterfly valve's performance and increasing maintenance costs.

[0005] To address the aforementioned issues, this application proposes an all-metal track-type high-sealing butterfly valve. Utility Model Content

[0006] This utility model addresses the technical problems existing in the prior art by providing an all-metal track-type high-sealing butterfly valve.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: an all-metal track-type high-sealing butterfly valve, including a valve body, an upper rotating shaft and a lower rotating shaft are provided inside the valve body, a butterfly plate is fixedly connected to the lower end of the upper rotating shaft, a positioning shaft is fixedly connected inside the butterfly plate, and a cleaning component and a dispersing component are rotatably connected to the side surface of the positioning shaft.

[0008] Preferably, the upper end of the lower rotating shaft is fixedly connected to the butterfly plate, and the lower end of the lower rotating shaft is rotatably connected to the valve body. By setting the lower rotating shaft and the upper rotating shaft on the same axis, the rotational force on the butterfly plate is more even, while the upper rotating shaft can withstand greater pressure and is less prone to damage.

[0009] Preferably, the cleaning assembly includes a first bearing and a scraper, the side surface of the first bearing is fixedly connected to the scraper, and the inner wall of the first bearing is rotatably connected to the positioning shaft.

[0010] Preferably, the scraper blade has an inclination angle of 30°, and there are three scraper blades arranged in a circular array. By setting the inclination angle of the scraper blades to 30°, they can rotate under the impact of the fluid.

[0011] Preferably, the disintegration assembly includes a second bearing and a crushing disc, the side surface of the second bearing is fixedly connected to the crushing disc, and the inner wall of the second bearing is rotatably connected to the positioning shaft.

[0012] Preferably, the tilt angle of the crushing disc is 45°, and the number of crushing discs is a number of blocks distributed in a circular array. By setting the tilt angle of the crushing disc to 45°, it can rotate faster than the scraper under the same fluid impact, and the tilt direction of the crushing disc is opposite to that of the scraper, so that it can rotate in the opposite direction relative to the scraper, thereby achieving the effect of breaking up the dirt scraped off by the scraper.

[0013] Preferably, a handle is fixedly connected to the upper end of the upper rotating shaft, a pressing handle is rotatably connected inside the handle, a locking block is fixedly connected to the right end of the pressing handle, a chuck is provided on the upper surface of the valve body, and a slot is provided on the side surface of the chuck, the slot being adapted to the locking block. By locking the locking block into the slot in the chuck, the handle is limited and cannot rotate, thereby preventing the upper rotating shaft connected below the handle from rotating, thus fixing the rotation angle of the butterfly plate connected to the upper rotating shaft and achieving flow restriction.

[0014] Preferably, bolts are inserted inside the valve body and the chuck, and nuts are threaded onto the side surfaces of the bolts. The cooperation between the bolts and nuts facilitates the installation of the chuck on the valve body.

[0015] Preferably, a spring is fixedly connected to the upper surface of the pressing handle, and the end of the spring away from the pressing handle is fixedly connected to the rotating handle. The spring force ensures that the locking block remains locked on the chuck, and the locking block can be disengaged from the slot simply by pinching the pressing handle, making the operation simpler and more convenient.

[0016] The beneficial effects of this utility model are:

[0017] 1. By setting up a cleaning component, the impact force generated by airflow or liquid flow drives the scraper to rotate. During the rotation of the scraper, the dirt on the butterfly plate is scraped off, so that the butterfly valve can automatically clean the dirt on the butterfly plate during use, improve the cleanliness of the butterfly plate, thereby reducing the number of times the butterfly valve needs to be repaired and maintained, and reducing maintenance costs.

[0018] 2. By setting up a dispersing component, it can work in conjunction with the cleaning component to disperse the dirt scraped off by the scraper, resulting in less residue in the fluid and preventing it from flowing into the next process and causing accumulation and blockage, thus further improving the cleaning effect.

The following description is provided to enable any person skilled in the art to implement and use the present invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0029] Reference Figure 1-5 The all-metal track-type high-sealing butterfly valve includes a valve body 1. Inside the valve body 1 are an upper rotating shaft 2 and a lower rotating shaft 3. A butterfly plate 4 is fixedly connected to the lower end of the upper rotating shaft 2. A positioning shaft 5 is fixedly connected inside the butterfly plate 4. A cleaning component and a dispersing component are rotatably connected to the side surface of the positioning shaft 5. The upper end of the lower rotating shaft 3 is fixedly connected to the butterfly plate 4, and the lower end of the lower rotating shaft 3 is rotatably connected to the valve body 1. By aligning the lower rotating shaft 3 and the upper rotating shaft 2 on the same axis, the rotational force on the butterfly plate 4 is more evenly distributed, while the upper rotating shaft 2 can withstand greater pressure and is less prone to damage. A handle 10 is fixedly connected to the upper end of the upper rotating shaft 2. A pressing handle 11 is rotatably connected inside the handle 10. A locking block 12 is fixedly connected to the right end of the pressing handle 11. A chuck 14 is provided on the upper surface of the valve body 1. A locking groove is provided on the side surface of the chuck 14, and the locking groove is compatible with the locking block 12. By engaging the locking block 12 into the slot in the chuck 14, the rotating handle 10 is limited and prevented from rotating. This prevents the upper rotating shaft 2 connected below the rotating handle 10 from rotating, thus fixing the rotation angle of the butterfly plate 4 connected to the upper rotating shaft 2 and achieving flow restriction. Bolts 15 are inserted inside the valve body 1 and the chuck 14, and nuts 16 are threaded onto the side surface of the bolts 15. The cooperation of bolts 15 and nuts 16 facilitates the installation of the chuck 14 on the valve body 1. A spring 13 is fixedly connected to the upper surface of the pressing handle 11, and the end of the spring 13 away from the pressing handle 11 is fixedly connected to the rotating handle 10. The elastic force of the spring 13 ensures that the locking block 12 remains engaged in the chuck 14. Simply squeezing the pressing handle 11 disengages the locking block 12 from the slot, making operation simpler and more convenient.

[0030] The cleaning assembly includes a first bearing 6 and a scraper 7. The side surface of the first bearing 6 is fixedly connected to the scraper 7, and the inner wall of the first bearing 6 is rotatably connected to the positioning shaft 5. The scraper 7 has an inclination angle of 30°, and there are three scrapers 7 arranged in a circular array. By setting the inclination angle of the scraper 7 to 30°, it can rotate under the impact of the fluid.

[0031] The dispersing assembly includes a second bearing 8 and a crushing disc 9. The side surface of the second bearing 8 is fixedly connected to the crushing disc 9, and the inner wall of the second bearing 8 is rotatably connected to the positioning shaft 5. The crushing disc 9 has an inclination angle of 45°, and there are 12 crushing discs 9 arranged in a circular array. By setting the inclination angle of the crushing disc 9 to 45°, it can rotate faster than the scraper 7 under the same fluid impact. Furthermore, the inclination direction of the crushing disc 9 is opposite to that of the scraper 7, allowing it to rotate in the opposite direction relative to the scraper 7, thereby achieving the effect of breaking up the dirt scraped off by the scraper 7.

[0032] Working principle:

[0033] In use, hold the end of the handle 10 and press the handle 11 with four fingers to compress the spring 13. The locking block 12 at the end of the handle 11 disengages from the slot on the chuck 14. Rotate the handle 10, and the upper shaft 2 and lower shaft 3 below the handle 10 drive the butterfly plate 4 to rotate. Then release the handle 11, and the locking block 12 engages with the corresponding slot, thus opening and limiting the butterfly plate 4. At this time, the fluid in the valve body 1 begins to flow, and the strong pressure pushes the scraper 7 to start rotating and scrape off the dirt on the butterfly plate 4. At the same time, the second bearing 8 reverses relative to the butterfly plate 4 under the action of pressure, breaking up the dirt scraped off by the butterfly plate 4.

[0034] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0035] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
