[0026] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0027] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0028] Figure 1 、 Figure 2 and Figure 3 The shown embodiment is a high-sealing, anti-slag-sticking, and heat-insulated ash valve, comprising a main valve housing 1 and a main valve core 2 installed inside the main valve housing 1. The arc-shaped inner walls on both sides of the main valve housing 1 are provided with inwardly protruding integral lateral sealing baffles 3. The main valve core 2 is longitudinally inserted into the inner wall of the main valve housing 1 through a centrally placed integral structure control shaft tube 4 and movably assembled with the main valve housing 1. An annular regulating chamber 5 is provided inside the main valve core 2. An arc-shaped receiving groove 6 connected to the annular regulating chamber 5 is provided on the inner side surface of the main valve core 2, which is located on the slag-facing side of the lateral sealing baffle 3. A flip scraper 7 is movably installed inside the arc-shaped receiving groove 6. An internal regulating ring 8 for controlling the flipping of the flip scraper 7 is movably installed inside the annular regulating chamber 5. A top speed-increasing linkage box 9 is fixedly installed on the upper end of the main valve core 2. A centrifugal pumping device 10 and a linkage speed-increasing mechanism are movably installed inside the top speed-increasing linkage box 9.

[0029] The control shaft tube 4 drives the main valve core 2 to flip inside the main valve housing 1 by rotating, and at the same time utilizes the linkage speed-increasing mechanism to drive the internal adjustment ring 8 to rotate inside the annular adjustment chamber 5, thereby driving the flip scraper plate 7 to flip synchronously to clean the scraper from the surface of the lateral sealing baffle 3.

[0030] In order to cooperate with the meshing linkage, the inner arc surface of the internal adjustment ring 8 is provided with an integrated structure linkage rack 11 that meshes and drives with the flip scraper plate 7.

[0031] In order to cooperate with the storage and flip adjustment, lateral assembly holes for assembling the flip scraper plate 7 are symmetrically opened on the inner side of the arc-shaped storage groove 6. The flip scraper plate 7 includes an internal adjustment disk 12 that is inserted into the lateral assembly holes and movably assembled with the arc-shaped storage groove 6 through the rotating shafts on both sides, an arc-shaped transmission tooth groove 13 opened on the outer arc surface of the internal adjustment disk 12, and a flip scraper 14 fixed on the outer surface of the internal socket disk 12.

[0032] In order to cooperate with the internal isolation transmission, the interior of the top speed-increasing linkage box 9 is divided into a centrifugal pumping chamber 15 for installing the centrifugal pumping equipment 10 and an internal speed-increasing chamber 16 for installing the linkage speed-increasing mechanism by a separation partition.

[0033] In order to achieve the linkage speed increase adjustment, the linkage speed increase mechanism includes an external linkage gear 17 fixed on the outer side of the control shaft tube 4, a first speed increase gear 18 meshing with the external linkage gear 17, a transmission gear 20 coaxially fixed with the first speed increase gear 18 through a first linkage shaft 19, and a second speed increase gear 21 meshing with the external linkage gear 17.

[0034] The main function is that when the control shaft tube 4 rotates 90 degrees, the flip scraper plate 7 can rotate 180 degrees.

[0035] In order to cooperate with the linkage control, the second speed-increasing gear 21 is inserted into the centrifugal pumping chamber 15 through the second linkage shaft 22 and is coaxially connected to the centrifugal pumping equipment.

[0036] In order to facilitate transmission adjustment, an arc-shaped control tooth groove 222 is formed on the outer side of the inner adjustment ring 8 to mesh with the transmission gear 20.

[0037] In order to coordinate lateral exhaust and internal diversion, an internal air guide channel 23 is opened inside the control shaft tube 4, and a lateral guide groove 24 is opened on the side wall of the control shaft tube 4 for connecting the internal air guide channel 23 with the lateral exhaust port of the centrifugal pumping chamber 15.

[0038] In order to cooperate with lateral exhaust and lateral air guidance, and to avoid blockage of the exhaust port, the outer side surface of the control shaft tube 4 is located on both sides of the connection end of the main valve core 2 and is provided with a strip exhaust port 25 connected to the lateral guide groove 24, and the strip exhaust port 25 is elastically equipped with a lateral closing cover 26.

[0039] The airflow generated by the high-speed rotation of the centrifugal exhaust device 10 is guided into the internal air flow channel 23 through the lateral guide groove 24, and then blown out from the strip exhaust port 25. As the air is blown out, the lateral closing cover 26 extends outward and then guides the airflow to the surface of the main valve core 2. The lateral closing cover 26 is automatically inserted into the strip exhaust port 25 by the lateral reset spring to elastically reset, thereby closing the strip exhaust port 25 and guiding the airflow.

[0040] In order to improve the thermal insulation performance of the ash valve, hollow thermal insulation chambers 27 are provided inside the main valve housing 1 near the outside and inside the main valve core 2.

[0041] The present invention relates to a high-sealing, anti-slag-sticking, heat-insulating ash valve with a high sealing performance. An internally mounted centrifugal pumping device 10 and a top-mounted speed-increasing linkage box 9 of a linkage speed-increasing mechanism are fixedly installed on the upper end of the main valve core 2. The centrifugal pumping device 10 and the linkage speed-increasing mechanism are used to remove the slag on the surface of the main valve core 2 and the inner wall of the main valve shell 1 when the control shaft tube 4 rotates, which greatly reduces the possibility of valve slag sticking and greatly reduces the difficulty of later maintenance. An arc-shaped receiving groove 6 is provided on the inner side surface of the main valve core 2 on the slag-facing side of the lateral sealing baffle 3, and a flip scraper plate 7 controlled by an internal adjusting ring 8 is movably installed inside the arc-shaped receiving groove 6. The flip scraper plate 7 can be used to flip and link the main valve core 2 to scrape the slag, thereby greatly improving the cleanliness of the sealing surface. The entire valve can synchronously control the slag discharge without the aid of electronic control equipment, greatly extending the later maintenance cycle, and lowering the equipment and maintenance costs. It adopts a purely mechanical structure design with a low failure rate. By adopting a built-in layout, it will not occupy the internal flow channel of the valve body, and the spatial layout is more reasonable.

[0042] With the above-described preferred embodiments of the present invention as a guide, and with reference to the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
