[0032] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0033] With reference to Figures 1 to 3 An embodiment provided by the utility model: electric air volume regulating valve blade anti -sticking adjusting mechanism, including valve body 1, both sides of valve body 1 are fixedly connected with flange ring 2, the flange ring 2 here is used to install this device into the ventilation system inside condenser, the top of valve body 1 is fixedly connected with the driving assembly for providing power, and the driving assembly includes support block 3, the bottom of support block 3 is fixedly connected at the top of valve body 1, the inner wall of support block 3 is fixedly connected with motor 4, the support block 3 here provides stable support for motor 4, and the driving end of motor 4 is fixedly connected with rotating shaft 5, which can drive the rotating shaft 5 to rotate after the start of motor 4, and the outer rotating connection of rotating shaft 5 is in the inner wall of valve body 1, and the valve body 1 here provides stable rotating support for rotating shaft 5.

[0034] The outer two ends of the driving assembly are fixedly connected with top sheets 6, and the two top sheets 6 are fixedly connected to the outer two ends of the rotating shaft 5, which can drive the top sheets 6 to rotate when the rotating shaft 5 rotates. The inner wall of the valve body 1 is fixedly connected with two rotating rings 7, and the inner wall of the rotating ring 7 is movably connected with a plurality of ball bearings 8. The rotating ring 7 provides a stable movement space for the ball bearings 8, and the top sheet 6 can drive the plurality of ball bearings 8 to rotate when the rotating shaft 5 rotates. The inner wall of the valve body 1 is rotatably connected with a valve leaf 9, and the inner wall of the valve leaf 9 is fixedly connected to the outside of the rotating shaft 5. When the rotating shaft 5 rotates, it will drive the valve leaf 9 to rotate, and the existence of the ball bearings 8 can minimize the friction during rotation to prevent jamming.

[0035] Referring to Figure 2 , Figure 4 and Figure 5 , the inner wall of the valve leaf 9 is fixedly connected with two support rings 10, which provide stable support for the valve leaf 9. The bottom end of the support ring 10 is slidably connected to the inner wall of the valve body 1, and the inner wall of the support ring 10 is movably connected with a ball bearing 11. The outer part of the ball bearing 11 is movably connected to the inner wall of the valve leaf 9, which provides a stable movement space for the ball bearing 11. The inner wall of the valve body 1 is provided with two sliding grooves 12, and when the valve leaf 9 rotates, it can drive the ball bearing 11 to slide in the inner wall of the sliding groove 12, further reducing the friction of the valve leaf 9 during rotation. The inner wall of the valve leaf 9 is slidably connected with a rubber block 13, which provides a stable sliding space for the rubber block 13. The inner wall of the valve body 1 is fixedly connected with a baffle 14 on both sides, which is used to press between the valve leaf 9 to form a sealed environment.

[0036] The rubber block 13 and the baffle 14 are in engagement, and the rubber block 13 is fixedly connected with a limiting block 15 away from the baffle 14. The limiting block 15 limits the sliding space of the rubber block 13 to prevent accidental disengagement from the sliding range of the valve leaf 9. The outer part of the limiting block 15 is slidably connected to the inner wall of the valve leaf 9, and the limiting block 15 is fixedly connected with a plurality of springs 16 on one side. The other end of the spring 16 is fixedly connected to the inner wall of the valve leaf 9. The spring 16 will be pressed by the baffle 14 when the valve leaf 9 is in a closed state, thereby generating a reaction force to make the rubber block 13 and the baffle 14 press more tightly, further improving the sealing performance.

[0037] Working principle: first, start the motor 4, make it drive the rotating shaft 5 rotation, in turn drive the valve blade 9 to open and close adjustment. While rotating shaft 5 rotates, the top piece 6 also rotates, this action further drives the ball 8 to roll in the rotating ring 7. The rolling of the ball 8 not only reduces the direct friction between the rotating shaft 5 and the inner wall of the valve body 1, but also plays a certain supporting role, so that the rotation of the rotating shaft 5 is more stable. At the same time, the ball 11 in the inner wall of the valve blade 9 slides in the sliding groove 12. This design also reduces the friction resistance when the valve blade 9 rotates, ensuring that the blade can be smoothly opened and closed.

[0038] In addition, the close cooperation between the rubber block 13 and the baffle 14 forms an effective sealing structure, preventing air leakage. When the valve blade 9 is in the closed state, the spring 16 is pressed by the baffle 14 to generate a counterforce, so that the extrusion between the rubber block 13 and the baffle 14 is more closely, thereby improving the sealing performance. The design of the whole device fully considers the needs of reducing friction, improving stability and enhancing sealing, so that the electric air volume regulating valve is more efficient and reliable in the running process.

[0039] Finally, it should be pointed out that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application is made with reference to the foregoing embodiments, for the skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of protection of the present application.
