Description

Technical Field

[0001] The utility model relates to the technical field of ball valves, in particular to a laminated self-cleaning ball valve. Background Art

[0002] Ball valves are commonly used in the chemical industry. When controlling the transportation of chemical wastewater, ball valves may encounter various blockage problems, which are mainly caused by the complex composition and particulate matter in chemical wastewater. Chemical wastewater may contain a large amount of suspended particles and sediments, which may accumulate in the flow channel inside the ball valve and gradually form sediments. Over time, the sediments will continue to accumulate, causing the flow channel of the ball valve to narrow, resulting in the inability of the internal parts of the ball valve to move normally or to seal poorly, or even complete blockage.

[0003] In the prior art, conventional laminated ball valves do not have a self-cleaning function. When impurities gradually accumulate on the inner wall of the internal flow channel of the ball valve, it will cause blockage, causing the ball valve to be unable to be used normally. When there are many impurities inside the ball valve, the flowing liquid needs to be closed and the ball valve needs to be disassembled before the inside of the ball valve can be discharged. This is time-consuming and labor-intensive and very inconvenient. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-3 , the present invention discloses a laminated self-cleaning ball valve, including a valve body 1, a seal cover assembly 2 is arranged on the upper surface of the valve body 1, a handle assembly 3 is arranged in the seal cover assembly 2, a valve core 4 is fixedly installed on the lower surface of the handle assembly 3, and the valve core 4 is installed in the valve body 1.

A slag discharge hole 12 is opened on the lower surface of the rectangular box 8, and a plug 13 is threadedly installed on the lower surface of the slag discharge hole 12.

[0021] Specifically, the cleaning mechanism 6 includes a rotating shaft 601, a bearing assembly 602, a turbine blade 603, a fixed rod 604 and a scraper 605. The rotating shaft 601 is fixedly installed on the upper side inner wall of the flow channel 5 through the bearing assembly 602. A turbine blade 603 is installed at the center position of the flow channel 5 on the rotating shaft 601. Scrapers 605 are installed on the left and right sides of the rotating shaft 601 through fixed rods 604.

[0022] In this implementation scheme, the turbine blade 603 rotates with the liquid flowing in the flow channel 5, so that the turbine blade 603 drives the rotating shaft 601 to rotate in the bearing assembly 602. The rotation of the rotating shaft 601 drives the scraper 605 on the fixed rod 604 to rotate. The scraper 605 scrapes off the impurities adhering to the inside of the flow channel 5 and makes the impurities flow towards the direction of the round hole 7.

[0023] Specifically, the scraping plate 605 has an arc-shaped structure, and the outer surface of the scraping plate 605 is movably attached to the inside of the flow channel 5.

[0024] In this embodiment, the scraping plate 605 can comprehensively scrape off the impurities adhering to the inner wall of the flow channel 5.

[0025] Specifically, the driving mechanism 9 includes a manual linear module 901, a mechanical seal 902, a handle 903, a hinge 904, and a connecting rod 905. There are two manual linear modules 901 arranged in a left-right mirror image, and the lead screws of the left and right manual linear modules 901 are fixedly connected. The manual linear module 901 is installed on the left side wall of the rectangular box 8 through the mechanical seal 902. A handle 903 is fixedly installed on the left end head of the manual linear module 901. Hinges 904 are provided on the front and rear sides of the sliding table of the manual linear module 901 and the front and rear sides of the moving plate 10, and the corresponding upper and lower hinges 904 are connected by a connecting rod 905.

[0026] In this embodiment, the handle 903 drives the lead screw of the left and right manual linear modules 901 to rotate, causing the sliding table of the left and right manual linear modules 901 to drive the lower hinge 904 to move left and right. The lower hinge 904 drives the connecting rod 905 to move, causing the connecting rod 905 to drive the moving plate 10 to move up and down. The outer surface of the sliding table of the manual linear module 901 has a rectangular structure, making the moving process more stable.

[0027] Specifically, an installation groove 14 is provided on the right inner wall of the rectangular box 8 corresponding to the manual linear module 901.

[0028] In this embodiment, the installation groove 14 is used for the lead screw of the right manual linear module 901 to be inserted, making the installation of the manual linear module 901 stable.

[0029] Specifically, the left and right sides of the moving plate 10 are movably attached to the left and right inner walls of the rectangular box 8. The moving plate 10 is made of a grid plate, and the distance between the front and rear sides of the moving plate 10 and the front and rear inner walls of the rectangular box 8 is 2 mm - 4 mm.

[0030] In this embodiment, the left and right sides of the moving plate 10 move up and down along the left and right inner walls of the rectangular box 8, making the up and down movement process of the moving plate 10 stable. At the same time, the moving plate 10 does not affect the downward flow of impurities.

[0031] In use, the left and right ports of the valve body 1 are docked with the pipeline. The handle assembly 3 drives the valve core 4 to rotate within the valve body 1, so that the flow channel 5 within the valve core 4 meets the liquid flow requirements. The liquid flowing into the flow channel 5 drives the turbine blade 603 in the cleaning mechanism 6 to rotate, causing the turbine blade 603 to drive the rotating shaft 601 to rotate within the bearing assembly 602. The rotation of the rotating shaft 601 drives the scraper 605 on the fixed rod 604 to rotate. The scraper 605 scrapes off the impurities adhering to the inside of the flow channel 5 and causes the impurities to flow towards the round hole 7. The impurities flow into the rectangular box 8 through the round hole 7, thereby increasing the cleaning function of the flow channel 5 within the valve core 4, effectively preventing impurities from accumulating in the flow channel 5 and causing blockage, and increasing the self-cleaning function of the ball valve. When it is necessary to discharge the impurities in the rectangular box 8, the handle 903 in the driving mechanism 9 drives the screw rod of the left and right manual linear modules 901 to rotate, causing the slide table of the left and right manual linear modules 901 to drive the lower hinge 904 to move left and right. The lower hinge 904 drives the connecting rod 905 to move, causing the connecting rod 905 to drive the moving plate 10 to move upward. The moving plate 10 drives the sealing plug 11 to move upward, causing the sealing plug 11 to insert into the round hole 7, achieving the effect of sealing the round hole 7. At this time, the plug 13 is removed, and the impurities in the rectangular box 8 are discharged through the slag discharge hole 12. Without closing and disassembling the ball valve, the impurities inside the ball valve can be discharged, facilitating the cleaning of the inside of the ball valve and being beneficial for use. Repeating the slag discharge operation several times can discharge the impurities in the rectangular box 8 more thoroughly. After the cleaning is completed, the plug 13 is first threadedly installed in the slag discharge hole 12, and then the sealing plug 11 is moved downward so that the impurities continue to flow into the rectangular box 8.

[0032] In summary, for this laminated self-cleaning ball valve, the cleaning function of the flow channel 5 within the valve core 4 is increased, effectively preventing impurities from accumulating and causing blockage of the flow channel 5. At the same time, without closing and disassembling the ball valve, the impurities inside the ball valve can be discharged, facilitating the cleaning of the inside of the ball valve and being beneficial for use.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
