Description

Technical Field

[0001] This utility model relates to the technical field of air valve devices, specifically a fully sealed, zero-leakage FRP air valve. Background Technology

[0002] In the field of modern prefabricated pumping stations, the operation of internal equipment generates heat, moisture, and harmful gases such as hydrogen sulfide and methane. To ensure stable equipment operation and personnel safety, stringent requirements are placed on the airtightness, adjustment accuracy, and driving efficiency of the air valves.

[0003] Existing air valves mostly use a multi-blade design, and each set of blades requires an independent drive motor for opening. This structure results in redundant motors, significantly increasing equipment procurement costs and the complexity of the control system, leading to high maintenance difficulty and costs. On the other hand, while traditional air valves emphasize sealing when the valve body is closed, they lack sealing structures at blade connections and in the dynamic contact area between the blades and the valve body. When the valve body is closed, airflow inside the prefabricated pumping station can easily leak through the gaps between the multiple sets of blades and between the multiple sets of blades and the valve body, reducing the sealing effect when the air valve is closed. To address the shortcomings of existing technology, we propose a fully sealed, zero-leakage FRP air valve to solve the above problems. Utility Model Content

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a fully sealed, zero-leakage FRP air valve, comprising a valve body, wherein a blade body is provided inside the valve body, and a rotary motor is provided on the top of the valve body. The rotary motor drives the blade body to rotate and is connected inside the valve body. The blade body is composed of a first blade, a second blade, and a third blade. The first blade, the second blade, and the third blade form a circle, and their outer walls are respectively attached to the inner peripheral wall of the valve body. The second blade and the third blade are respectively located on both sides of the first blade, and their outer walls are respectively attached to the outer walls of both sides of the first blade.

[0005] The valve body is provided with a linkage component at the top. The linkage component links multiple sets of blades with a rotary motor. The linkage component simultaneously drives multiple sets of blades to rotate and connect inside the valve body. The valve body is provided with a sealing component inside. The sealing component performs sealing operations between multiple sets of blades and between multiple sets of blades and the valve body.

[0006] Preferably, blade shaft one, blade shaft two, and blade shaft three are fixedly installed in the middle part of the first blade, the second blade, and the third blade, respectively. The bottom ends of blade shaft one, blade shaft two, and blade shaft three are rotatably connected to the bottom of the valve body, and the top ends of blade shaft one, blade shaft two, and blade shaft three pass through the top of the valve body and are connected to the linkage assembly.

[0007] Preferably, a fixing frame is fixedly installed on the top of the valve body, and the linkage component is installed inside the fixing frame.

[0008] Preferably, the linkage assembly includes a linkage rack, a transmission gear, a first limiting plate, and a second limiting plate. The linkage rack slides along the length direction of the fixed frame, and the first limiting plate and the second limiting plate are respectively fixedly installed on the outer walls of both sides of the linkage rack.

[0009] Preferably, the multiple sets of transmission gears mesh on one side of the linkage rack, and the multiple sets of transmission gears are equidistantly distributed, and the multiple sets of transmission gears are fixedly connected to blade shaft one, blade shaft two and blade shaft three respectively.

[0013] This utility model discloses a fully enclosed, zero-leakage FRP (fiberglass reinforced plastic) air valve, which has the following beneficial effects: This fully enclosed, zero-leakage FRP air valve uses a linkage component to link the rotating motor and multiple sets of blades, avoiding the need for a separate drive motor for each set of blades, reducing the number of motors and the complexity of the control system, and lowering equipment procurement and installation costs. When multiple sets of blades rotate in linkage, the overall rotational inertia distribution is more uniform, enabling rapid opening and closing, and precise adjustment of blade opening to control airflow or fluid flow. Simultaneously, a sealing component is installed, with multiple sealing plates arranged according to the rotation direction of the multiple sets of blades. When the valve body is closed, the sealing plates can tightly adhere to the blade edges, preventing media leakage from the gap between the blades and the valve body, thus improving sealing performance. While ensuring sealing at the connection points of multiple sets of blades and the connection points between the multiple sets of blades and the valve body, it does not affect the rotation of the multiple sets of blades. In prefabricated pumping stations, it achieves the goals of efficient drive, precise control, and zero leakage, providing technical support for the intelligent and safe operation of prefabricated pumping stations.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] This utility model embodiment discloses a fully sealed, zero-leakage FRP air valve.

[0025] According to the appendix Figure 1-6 As shown, the device includes a valve body 1, which is mainly made of fiberglass. Inside the valve body 1, there is a blade body 2. A rotary motor 3 is installed on the top of the valve body 1. The rotary motor 3 drives the blade body 2 to rotate and is connected inside the valve body 1. The blade body 2 is composed of a first blade 21, a second blade 22, and a third blade 23. The first blade 21, the second blade 22, and the third blade 23 form a circle, and their outer walls are respectively attached to the inner circumferential wall of the valve body 1. The second blade 22 and the third blade 23 are located on both sides of the first blade 21, and their outer walls are respectively attached to the outer walls on both sides of the first blade 21. During use, the valve body 1 mainly plays the role of controlling airflow, regulating ventilation volume, and ensuring the safe operation of equipment in the prefabricated pumping station. The prefabricated pumping station usually contains equipment such as water pumps and motors, which generate heat, moisture, and potentially harmful gases during operation. By opening or closing the air valve, the airflow direction of the ventilation system can be controlled to ensure air circulation in the pumping station and avoid the accumulation of gas that may cause safety hazards.

[0026] A linkage component 4 is provided on the top of the valve body 1. The linkage component 4 links multiple sets of blades with the rotary motor 3. The linkage component 4 simultaneously drives multiple sets of blades to rotate and connect inside the valve body 1. A sealing component 5 is provided inside the valve body 1. The sealing component 5 seals between multiple sets of blades and between multiple sets of blades and the valve body 1. By starting the rotary motor 3, multiple sets of blades can rotate simultaneously inside the valve body 1 with the cooperation of the linkage component 4, thereby enabling the opening of multiple sets of blades, controlling the airflow direction of the ventilation system, ensuring air circulation in the pump station, and controlling the opening angle of multiple sets of blades through the rotary motor 3, thereby controlling the airflow and adjusting the ventilation volume.

[0027] The inner middle parts of the first blade 21, the second blade 22, and the third blade 23 are respectively fixedly installed with blade shaft 1 211, blade shaft 221, and blade shaft 3 231. The bottom ends of blade shaft 1 211, blade shaft 221, and blade shaft 3 231 are rotatably connected to the bottom of the valve body 1. The top ends of blade shaft 1 211, blade shaft 221, and blade shaft 3 231 pass through the top of the valve body 1 and are connected to the linkage assembly 4. When the first limiting plate 43 is attached to the outer wall of one side of the transmission gear 42, the multiple sets of blades are in a fully open state, which maximizes the ventilation volume. For details, please refer to the appendix. Figure 3 Conversely, when the second limiting plate 44 is attached to one side of the transmission gear 42, multiple sets of blades are in the closed state. See the attached document for details. Figure 2 It can completely seal the inside of the pump station, preventing the airflow inside the pump station from leaking out through the valve body 1.

[0028] A fixed frame 6 is fixedly installed on the top of the valve body 1. The linkage assembly 4 is installed inside the fixed frame 6. The linkage assembly 4 includes a linkage rack 41, a transmission gear 42, a first limiting plate 43, and a second limiting plate 44. The linkage rack 41 slides along the length of the fixed frame 6. The first limiting plate 43 and the second limiting plate 44 are respectively fixedly installed on the outer walls of both sides of the linkage rack 41. By starting the rotary motor 3, the rotary motor 3 drives a set of transmission gears 42 to rotate. Through the meshing action between the transmission gears 42 and the linkage rack 41, the linkage rack 41 can simultaneously drive multiple sets of transmission gears 42 to rotate inside the fixed frame 6. This allows multiple sets of blade shafts to drive multiple sets of blades to rotate inside the valve body 1, opening or closing the valve body 1 and controlling the flow of air.

[0029] Multiple sets of transmission gears 42 mesh on one side of the linkage rack 41, and the multiple sets of transmission gears 42 are equidistantly distributed. The multiple sets of transmission gears 42 are fixedly connected to blade shaft one 211, blade shaft two 221, and blade shaft three 231, respectively. The rotary motor 3 is fixedly installed on the top of the fixed frame 6, and the output end of the rotary motor 3 is fixedly connected to one set of transmission gears 42. When the multiple sets of blades are opened, the multiple sets of blades move in accordance with... Figure 4 Rotate in the direction of the center arrow. During rotation, the multiple sets of sealing plates will not affect the rotation of the multiple sets of blades, making the operation of the multiple sets of blades smoother. Please refer to the appendix for details. Figure 5 .

[0030] The sealing assembly 5 includes a first semi-annular plate 51, a second semi-annular plate 52, a first rectangular plate 53, and a second rectangular plate 54. The first semi-annular plate 51 and the second semi-annular plate 52 are respectively fixedly installed on the inner walls of both sides of the valve body 1 and are located on both sides of the blade body 2. When multiple sets of blades are in the closed state, the two sets of semi-annular plates are located on both sides of the blade shaft 221 and the blade shaft 231, respectively, which can block and seal the connection between the blade shaft 221, the blade shaft 231 and the valve body 1. At the same time, the two sets of rectangular plates They are respectively attached to the outer walls on both sides of the first blade shaft 211 and located at the connection between the second blade shaft 221, the third blade shaft 231 and the first blade shaft 211, thereby blocking and sealing the connection between the second blade shaft 221, the third blade shaft 231 and the first blade shaft 211, ensuring that the valve body 1 can be fully sealed when closed, preventing airflow from leaking through the gaps between the multiple sets of blades and the gaps between the multiple sets of blades and the valve body 1, achieving complete sealing and realizing no leakage when the valve body 1 is closed.

[0031] The first rectangular plate 53 and the second rectangular plate 54 are respectively fixedly installed on the outer walls of the second blade 22 and the third blade 23, and are located on both sides of the blade body 2. The first semi-ring plate 51 and the first rectangular plate 53 are on the same side, and the second semi-ring plate 52 and the second rectangular plate 54 are on the same side. The multiple sets of sealing plates are arranged according to the direction of rotation of the multiple sets of blades. While ensuring the sealing of the connection of the multiple sets of blades and the connection between the multiple sets of blades and the valve body 1, the rotation of the multiple sets of blades will not be affected.
