[0002] Air volume control valve plays an important role in air conditioning and ventilation system. It can control and adjust the air volume in the ventilation system. By adjusting the opening of the air volume control valve, the air supply volume can be changed, so that the air conditioning system can meet the ventilation requirements of different places and needs. The air supply volume can be flexibly adjusted according to actual needs, which can effectively control energy consumption and avoid oversupply or waste, thereby saving energy and reducing operating costs.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-Figure 4 As shown, the utility model proposes an air volume regulating valve for an air conditioning and ventilation system, comprising a motor 1, a mounting frame 2, a rotating shaft 4, a mounting box 7, a travel frame 8 and a card plate 19, wherein the motor 1 is arranged at the upper end of the mounting frame 2, a valve seat 3 is arranged inside the mounting frame 2, a rotating shaft 4 is arranged at the output end of the upper end of the motor 1, the lower end of the rotating shaft 4 is rotatably mounted inside the mounting frame 2, a valve leaf 5 mounted on the inner wall of the valve seat 3 is sleeved on the outer wall of the rotating shaft 4, a mounting sleeve 16 fixed to the upper end of the mounting frame 2 is sleeved on the outer side of the rotating shaft 4, a valve leaf 5 is arranged inside the mounting sleeve 16, and mounting shafts 18 rotatably mounted on the inner wall of the mounting sleeve 16 are arranged at both upper and lower ends of the valve leaf 5, a torsion spring 21 is sleeved on the outer wall of the mounting shaft 18, equidistantly distributed rotating plates 20 are sleeved on the outer wall of the rotating shaft 4, a bracket 6 is sleeved on the outer wall of the motor 1, and the lower end of the bracket 6 is connected to the inner wall of the upper end of the mounting frame 2. The rotating shaft 4 is provided with equidistantly distributed rotating rods 22 at one end outside the mounting frame 2, and mounting flanges are provided at both ends of the mounting frame 2. A stopper 17 fixed to the inner wall of the mounting sleeve 16 is provided on one side of the clamping plate 19. The bracket 6 is sleeved on the outer wall of the motor 1 and fixed on the upper end of the mounting frame 2.

[0022] The implementation steps based on Example 1 are as follows: by docking the mounting flange with the ventilation duct in the air conditioning and ventilation system, the rotating shaft 4 drives the valve leaf 5 to rotate, and the opening of the mounting seat is controlled, and the air volume output by the air conditioner is controlled, and when the rotating shaft 4 rotates clockwise, the rotating plate 20 is driven to rotate, and the card plate 19 is rotated by the rotating shaft 4, and the card plate 19 is reset by the torsional elasticity of the torsion spring 21. When the rotating shaft 4 rotates in the opposite direction, it is intercepted by the limit block 17, and the rotated valve leaf 5 is controlled. The control valve leaf 5 can be subjected to the action of the rotational torque. When the card plate is driven to rotate by manual operation or the motor 1, the card plate 19 is driven to rotate by the motor 1. When the plate 19 is pressed, the torque will be transmitted to the control valve leaf 5 through the clamping plate 19, causing it to rotate, thereby adjusting the opening and closing state of the control valve leaf 5. The air volume can be adjusted by manually rotating and pushing the clamping plate 19. When the motor 1 cannot be used, there is no need to rely on the motor 1 or the automation system. The valve leaf 5 can be adjusted by manually grasping the rotary rod 22 to rotate the shaft 4. The air volume regulating valve design that can support both manual and motor 1 control is adopted to improve the flexibility, efficiency and integration of the air volume regulating valve to meet complex needs. In actual applications, appropriate control methods are selected according to specific circumstances.
