[0001] This utility model relates to the field of lift valve technology, and in particular to a lift valve for an RTO waste gas incineration system. Background Technology
[0002] The RTO lift valve is the core switching device of the regenerative thermal ignition (RTO) system. By precisely controlling the opening and closing of the valve plate, it enables the directional flow of waste gas between multiple regenerator chambers and the efficient recovery of heat, ensuring the continuous and stable operation of the system and its purification efficiency.
[0003] Traditional lift valves typically consist of a valve body, valve plate, connecting rod, cylinder, and frame. The cylinder is connected to the valve body via the frame, while the cylinder output end is fastened to the connecting rod using flange bolts. However, due to the limited internal space of the frame, the fastening bolts between the cylinder output end and the connecting rod are difficult to operate and disassemble during cylinder installation or maintenance, increasing assembly difficulty. Therefore, this solution proposes a lift valve for RTO waste gas incineration systems to solve the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] This utility model provides, for example Figure 1-4 A lift valve for an RTO waste gas incineration system is shown, comprising:
[0026] Frame 1;
[0027] Sealing plate 2 is inserted and connected inside the frame 1;
[0028] Connecting rod 3 is fixedly connected to the top of sealing plate 2;
[0029] Cylinder 4 is located on the top of frame 1 and is used to move the position of connecting rod 3.
[0030] Linkage component 5 includes a trapezoidal slot 502 at the bottom of cylinder 4, a trapezoidal block 501 is inserted inside the trapezoidal slot 502, a connecting member is provided at the top of the connecting rod 3 to connect the connecting rod 3 and the trapezoidal block 501, and a moving member is provided at the bottom of the trapezoidal block 501 to move the position of the trapezoidal block 501.
[0031] A mounting bracket 7 is fixedly connected to the top of the frame 1, and the output end of the cylinder 4 is inserted and connected to the top of the mounting bracket 7.
[0032] It should be noted that the mounting bracket 7 is fixedly connected to the frame 1 by welding. A hole is provided at the top of the mounting bracket 7, allowing the output end of the cylinder 4 to pass through the hole. The cylinder 4 is fixedly connected to the top of the mounting bracket 7 by bolts. A connecting flange is provided at the connection point between the frame 1 and the pipeline, allowing the frame 1 to be connected to the pipeline during use. The trapezoidal locking block 501 is adapted to the trapezoidal locking slot 502, and both are isosceles trapezoids, allowing the trapezoidal locking block 501 to be inserted into the trapezoidal locking slot 502, thus restricting the movement direction of the trapezoidal locking block 501. A sealing ring is provided at the connection point between the sealing plate 2 and the frame 1, sealing the connection point during use and preventing liquid from passing through the sealing plate 2 and the frame. The connection point of body 1 overflows. The connecting rod 3 is inserted and connected to the top of the frame 1. During use, the connecting rod 3 drives the sealing plate 2 to move. A sealing ring is provided at the connection point between the connecting rod 3 and the frame 1 to seal the connection point, preventing liquid from overflowing. When it is necessary to connect the connecting rod 3 and the output end of the cylinder 4, the cylinder 4 is first installed in the required position. Then, the moving part drives the trapezoidal locking block 501 to move, so that the trapezoidal locking block 501 moves into the trapezoidal slot 502 at the bottom of the cylinder 4. The connection between the connecting rod 3 and the output end of the cylinder 4 is connected through the cooperation of the trapezoidal locking blocks 501, thereby avoiding the situation where it is difficult to connect the cylinder 4 and the connecting rod 3 due to the obstruction of the mounting bracket 7.
[0033] Specifically, the connector includes a through block 503 fixedly connected to the bottom of the trapezoidal block 501, a sliding block 507 fixedly connected to the bottom end of the through block 503, a fixing block 505 fixedly connected to the top end of the connecting rod 3, a through groove 504 opened at the top end of the fixing block 505, a sliding groove 510 opened on the inner wall of the bottom end of the through groove 504, the through block 503 is inserted into the inside of the through groove 504, and the sliding block 507 is inserted into the inside of the sliding groove 510.
[0034] It should be noted that the sliding groove 510 is adapted to the sliding block 507, allowing the sliding block 507 to slide inside the sliding groove 510. The through groove 504 is adapted to the through block 503, allowing the through block 503 to slide inside the through groove 504. The through block 503 connects the sliding block 507 located inside the sliding groove 510 and the trapezoidal locking block 501 located on top of the fixing block 505. The through block 503 prevents the sliding block 507 from rotating.
[0035] Specifically, the moving part includes a threaded rod 509 threadedly connected to the middle of the sliding block 507. A limiting member 6 for limiting the moving direction of the sliding block 507 is provided on one side of the sliding block 507. A knob 508 is fixedly connected to one end of the threaded rod 509. A fixed bearing 506 is sleeved on one side of the threaded rod 509. The fixed bearing 506 is located on the inner wall of one side of the sliding groove 510.
[0036] It should be noted that the fixed bearing 506 is an existing ball bearing. During use, the fixed bearing 506 fixes the position of the threaded rod 509 without affecting its rotation. When it is necessary to move the position of the sliding block 507, the threaded rod 509 is rotated, and the rotating threaded rod 509 drives the sliding block 507, which is threaded to it and cannot rotate, to move.
[0037] Example 2: Limiting component 6, applied to the lift valve in Example 1;
[0038] Specifically, the limiting component 6 includes a limiting rod 603 fixedly connected to the inner wall of one side of the sliding groove 510, a limiting groove 601 is provided on one side of the sliding block 507, the limiting rod 603 is inserted into the inside of the limiting groove 601, a locking block 604 is fixedly connected to one end of the limiting rod 603, and a locking groove 602 is provided on the other side of the sliding block 507.
[0039] It should be noted that the limiting rod 603 is adapted to the limiting groove 601, allowing the limiting rod 603 to slide inside the limiting groove 601; the locking groove 602 is adapted to the locking block 604, allowing the locking block 604 to be inserted into the locking groove 602. The diameter of the locking block 604 is larger than the diameter of the limiting groove 601, so that after the locking block 604 moves to the inner wall of the locking groove 602 and fits against it, the sliding block 507 cannot continue to move due to the blocking effect of the locking block 604, thus limiting the movement distance of the sliding block 507.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
