Description

Technical Field

[0001] The utility model relates to the technical field of air valves, in particular to an energy-efficient structure of an air valve. Background Technique

[0002] An air valve is a device used to control the air flow rate and direction, guiding the air to a specific direction or area to achieve uniform air distribution. The air valve can ensure that each area can obtain appropriate ventilation effects, close or open the air, and when it is necessary to stop or start the ventilation of a certain air duct, the air valve can be completely closed or opened to achieve flexible control of the air volume output and other requirements. Among them, a manual air valve requires manual operation to adjust the blade angle.

[0003] The main functions of the air valve include adjusting the air volume. By changing the blade angle of the air valve, the air volume passing through the pipeline is controlled to meet the air volume requirements of different areas and equipment. The air valve plays an important role, but after long-term use, problems such as blade rusting and aging will occur, thus affecting the airtightness of the air valve pipeline.

[0004] The air valve is installed in the ventilation pipe. At the same time, when the air valve adjusts the air volume, it will generate a certain resistance in the air duct, resulting in an increase in the pressure loss of the system. A blower with a greater power is required to maintain the required air volume. The adjustment accuracy of the manual air valve is limited, and its adjustment accuracy may not be precise enough, making it difficult to achieve fine control of the air volume. During the long-term use of the air valve, problems such as component wear and blockage will occur, and regular replacement is required, greatly increasing the energy consumption and the cost of maintaining the air valve. Content of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides an energy-efficient structure of an air valve, aiming to improve the problems of component wear and blockage that occur in the existing air valve during long-term use.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme: an energy-efficient structure of an air valve, including an air valve barrel. The upper end of the inner wall of the air valve barrel is rotatably connected with a turning handle. The bottom end of the turning handle is fixedly connected with a rhombic groove. The upper end of the inside of the air valve barrel is rotatably connected with a rhombic groove. A blade fixing plate is arranged at the bottom of the rhombic groove. The upper right side of the blade fixing plate is fixedly installed with a blade pressing plate. A first fixing hole is opened at the lower end of the outer wall of the blade fixing plate. A spring is fixedly installed inside the first fixing hole. A second fixing hole is opened at the bottom of the inner wall of the air valve barrel. A telescopic column is installed inside the second fixing hole. A blade mechanism is installed inside the air valve barrel.

[0007] As a further description of the above technical solution:

[0008] The blade mechanism includes a rhombic block which is engaged inside the rhombic groove. A second gear is fixedly connected to the bottom of the rhombic block. On the upper right side of the top end of the fan blade shaft, a first gear is rotatably connected. The second gear is meshed with the first gear. The first gear is rotatably connected to the outside of the fan blade shaft. A fixing frame is fixedly connected to the fan blade shaft, and the fixing frame is fixedly connected to the outside of the blade fixing plate. A second blade is fixedly connected to the outer wall of the fan blade shaft, and a first blade is fixedly connected to the left end of the first gear.

[0009] As a further description of the above technical solution:

[0010] A grip is rotatably connected to the upper end of the rotary handle.

[0011] As a further description of the above technical solution:

[0012] A scale disk is arranged at the bottom of the grip. A pointer is installed inside the scale disk, and the pointer is fixedly connected to the outside of the grip.

[0013] As a further description of the above technical solution:

[0014] A fixing groove is arranged on the right side of the scale disk. A sealing plate is installed inside the fixing groove. The sealing plate is slidably connected to the upper end of the inner wall of the air valve barrel, and a slot is opened at the front end of the sealing plate.

[0015] As a further description of the above technical solution:

[0016] A snap ring is arranged on the right side of the sealing plate. A snap fastener is installed on the right side of the snap ring, and the snap ring is engaged with the snap fastener.

[0017] As a further description of the above technical solution:

[0018] A bolt is threadedly connected to the lower end of the snap ring, and a screw hole is opened on the right side of the bolt.

[0019] As a further description of the above technical solution:

[0020] A sealing strip is installed at the lower end of the screw hole, and a filter screen is installed on the left side of the sealing strip.

[0021] The utility model has the following beneficial effects:

[0022] 1. In the utility model, considering the convenience of cleaning and maintenance, the product is also equipped with a detachable blade design. When in use, the sealing plate is opened, and the blade mechanism is disassembled by pressing the pressing plate downward. After the blade is disassembled, it can be cleaned and reused repeatedly, reducing the cost and expense of regular maintenance, avoiding the occurrence of wear and blockage, enabling the normal operation of the entire air valve, reducing the cost of maintaining the air valve, and saving energy.

[0023] 2. In the present utility model, the rotation of the turning handle drives the gear to rotate, and the first blade and the second blade are staggered, thereby controlling the air volume. At the same time, the method of controlling the air volume by the double blades can more accurately grasp the air volume, keep the indoor environment in an ideal state for a long time, effectively reduce energy consumption. By optimizing the blade shape, in terms of appearance design, the wind resistance and power are reduced to reduce energy consumption. Further, the adjustment of the air volume becomes more accurate, and the rotation angle of the turning handle is manually adjusted to achieve a stable air volume output.
