Technical Field

[0001] The utility model relates to the technical field of valves, in particular to an adaptive atmospheric gate valve. Background Art

[0002] Factors such as pipeline layout and changes in pipeline diameter can cause unstable gas flow in the pipeline, causing flow fluctuations. Therefore, it is necessary to adjust the valve to keep the flow at the pipeline outlet stable. Ordinary valves usually require manual operation to adjust the valve opening, which requires manual real-time monitoring and adjustment. At the same time, they are easily affected by human factors when adjusting the gas flow, and have low accuracy, making it difficult to achieve precise flow control, especially in processes that require high-precision control. In view of this, the utility model proposes an adaptive large gate valve. Utility Model Content

[0022] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] The components of the embodiments of the present invention generally described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

[0024] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] like Figure 1 As shown, the utility model proposes an adaptive large air valve, including a valve body 1, an air inlet 2 and an air outlet 3, wherein the air inlet 2 is connected to the air inlet pipe, and the air outlet 3 is connected to the air outlet pipe. It also includes a gas flow meter 4 installed in the air outlet 3 for monitoring the flow rate, and the gas flow meter 4 is used to monitor the flow rate of the gas when it passes through the regulating mechanism 5, and send a signal to the motor control start, and control the servo motor 66 through the motor controller.

[0028] For details, please refer to Figure 2 and Figure 3The valve includes an adjusting mechanism 5 disposed in the valve body 1, and a control assembly 6 for driving the adjusting mechanism 5 to adjust the flow rate. The adjusting mechanism 5 includes a fixed block 51, a vent 52, a valve plate 53, and an adjusting hole 54. The U-shaped fixed block 51 is installed inside the valve body 1, and the position of the fixed block 51 is fixed. The circular vent 52 is provided on the fixed block 51 and its position corresponds to the air inlet 2 and the air outlet 3, so as to facilitate the passage of gas. The valve plate 53 is slidably connected to the fixed block 51, and a semicircular adjusting hole 54 is provided on the valve plate 53, and the adjusting hole 54 corresponds to the vent 52. The valve plate 53 is used to reduce the flow rate of gas when moving downward. The adjusting mechanism 5 also includes a moving rod 55 and a synchronous plate 56. Three groups of moving rods 55 are equidistantly arranged and fixedly connected to the top of the valve plate 53. The moving rod 55 drives the valve plate 53 to move when moving. The moving rod 55 passes through the fixed block 51 and the top of the valve body 1, and at the same time makes the movement of the valve plate 53 stable. The synchronous plate 56 is fixedly connected to the top of the three groups of moving rods 55. When the synchronous plate 56 moves, it drives the three groups of moving rods 55 to move synchronously. The adjustment mechanism 5 also includes a rubber sealing sleeve 57 sleeved on the outer ring of the synchronous plate 56. The rubber sealing sleeve 57 is installed on the top of the fixed block 51. The rubber sealing sleeve 57 is used to enhance the sealing performance, prevent gas leakage, and ensure the stability of the gas flow in the valve body 1.

[0029] Further, such as Figure 1 and Figure 3 As shown, the control assembly 6 includes a fixed frame 61, a fixed rod 62, a fixed sleeve 63, and a limit rod 64. The U-shaped fixed frame 61 is fixedly connected to the top of the valve body 1, and the position of the fixed frame 61 is fixed. Two groups of fixed sleeves 63 are symmetrically arranged on both sides of the fixed frame 61. The fixed sleeve 63 and the fixed frame 61 are fixedly connected through two groups of fixed rods 62. The fixed rods 62 fix the position of the fixed sleeve 63. The limit rod 64 is fixedly connected to the top of the synchronous plate 56, and the limit rod 64 moves synchronously with the synchronous plate 56. The control assembly 6 also includes a top plate 65, a servo motor 66, and a threaded rod 67. The top plate 65 is fixedly connected to the top of the two groups of limit rods 64. The limit rod 64 is slidably connected in the fixed sleeve 63. Under the limiting action of the fixed sleeve 63 and the limit rod 64, the top plate 65 moves smoothly. The servo motor 66 is installed on the top of the top plate 65. The output end of the servo motor 66 penetrates the top plate 65 and is fixedly connected to the threaded rod 67. The servo motor 66 is connected to the motor control for accurate control. The servo motor 66 is used to drive the threaded rod 67 to rotate after starting. The threaded rod 67 is threadedly connected to the fixed frame 61. When the threaded rod 67 rotates, it can move along its own length direction. The end of the threaded rod 67 away from the servo motor 66 penetrates the fixed frame 61 and is rotatably connected to the top of the synchronous plate 56, so that the threaded rod 67 drives the synchronous plate 56 to move synchronously when moving, and drives the limit rod 64 and the top plate 65 to move synchronously at the same time.

[0030] In this embodiment, the air inlet 2 is first connected to the air inlet pipe, and the air outlet 3 is connected to the air outlet pipe. When the gas enters the valve body 1 through the air inlet 2, passes through the ventilation hole 52 and the adjustment hole 54, and passes through the position of the gas flow meter 4, the gas flow meter 4 monitors the flow in real time. The gas flow meter 4 transmits the flow information at that time to the motor controller, and the motor controller starts the servo motor 66, and the servo motor 66 drives the threaded rod 67 to rotate. Since the threaded rod 67 is threadedly connected to the fixed frame 61, the threaded rod 67 rotates and moves downward, and at the same time drives the synchronous plate 56 connected to the bottom of the threaded rod 67 to move downward. At this time, the synchronous plate 56, the limit rod 64, and the top plate 65 move downward steadily under the limiting action of the fixed sleeve 63. At the same time, the valve plate 53 is driven to slide downward in the fixed block 51 by multiple groups of moving rods 55. At this time, the position of the gas passing through the ventilation hole 52 and the adjustment hole 54 is reduced, and the gas flow is reduced. The gas flow meter 4 monitors the flow in real time. When the flow reaches the preset value, the motor controller stops the servo motor 66. At the same time, when the gas flow in the pipeline fluctuates, the flow rate can be adjusted in time to keep the flow at the outlet stable.

[0031] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
