[0002] The Venturi airflow control valve combines a mechanical pressure-independent regulator with a high-speed airflow controller to extend airflow control to the highest level. Through aerodynamic design, the valve has silent working performance.
[0003] However, the existing variable air volume Venturi parallel valve generally uses a push rod motor as an actuator when in use. When the air volume needs to be adjusted, the push rod motor drives the two sets of mechanisms to achieve the effect of air volume adjustment. However, the push rod motor is not suitable for long-term continuous work. If it is frequently operated, the motor will overheat and malfunction, and the valve will lose its control function.
[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a variable air volume Venturi parallel valve with a one-push-two angle actuator mechanism is proposed. Utility Model Content

DETAILED DESCRIPTION
[0018] 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.
[0019] Embodiment 1: Figure 1-Figure 3As shown, a variable air volume Venturi parallel valve with a one-push-two angle actuator mechanism comprises a valve body 1, an outer wall of the valve body 1 is provided with a large torque angle actuator body 2, an output end of the large torque angle actuator body 2 is fixedly connected with a rotating shaft 3 rotatably connected to the outer wall of the valve body 1, one end of the rotating shaft 3 is rotatably connected with a bracket 10 fixedly connected to the outer wall of the valve body 1, a connection portion between the outer wall of the bracket 10 and the rotating shaft 3 is provided with a wear-resistant self-lubricating copper sleeve 11, an outer wall of the rotating shaft 3 is fixedly connected with a rotating rod 4 rotatably connected to the outer wall of the valve body 1, one end of the rotating rod 4 is rotatably connected with a swing rod 5, one end of the swing rod 5 is rotatably connected with an adjusting rod 6 rotatably connected to the outer wall of the valve body 1, one end of the adjusting rod 6 is rotatably connected with a sliding guide rod 7 telescopically connected to the inner wall of the valve body 1, the outer wall of the sliding guide rod 7 is slidably connected with a limit frame 8 fixedly connected to the inner wall of the valve body 1, and one end of the adjusting rod 6 is rotatably connected with a telescopic guide rod 12 located on one side of the sliding guide rod 7.
[0020] Furthermore, the adjusting rod 6 is connected to the sliding guide rod 7 by a connecting hook 9. By setting the adjusting rod 6, it is beneficial to improve the linkage of the internal air volume adjustment of the variable air volume Venturi parallel valve during daily use of the variable air volume Venturi parallel valve, reduce the energy loss driven by the electric push rod, and reduce the stability of the working state of the variable air volume Venturi parallel valve driven by the electric push rod for a long time. When the air volume in the valve needs to be adjusted, the large torque angle actuator body 2 can be opened, and the rotating rod 4 can be driven to rotate by the rotation of the rotating shaft 3. The rotation of the rotating rod 4 drives the adjusting rod 6 to rotate effectively along the valve through the connection of the swing rod 5, and drives the sliding guide rod 7 and the telescopic guide rod 12 to slide synchronously back and forth along the inner wall of the limit frame 8 through the connection of the connecting hook 9, so as to achieve the effect of synchronously adjusting the air volume in the valve.
[0021] Furthermore, two groups of rotating rods 4 and swing rods 5 are provided, and the position distribution of the two groups of rotating rods 4 and swing rods 5 is symmetrical about the central axis of the rotating shaft 3. By providing two groups of rotating rods 4 and swing rods 5 whose position distribution is symmetrical about the central axis of the rotating shaft 3, the sliding guide rod 7 and the telescopic guide rod 12 are driven to reciprocate in coordination.
[0022] Furthermore, one end of the adjusting rod 6 extends to the interior of the valve body 1 and is connected to the sliding guide rod 7 for movement. The adjusting rod 6 forms a rotating structure with the valve body 1 through the rotating rod 4 and the swing rod 5, which is beneficial to the rotation of the rotating rod 4 through the connection with the swing rod 5, thereby driving the adjusting rod 6 to effectively rotate along the outer wall of the valve body 1, thereby driving the sliding guide rod 7 to slide back and forth.
[0023] Furthermore, installation grooves are provided at the connection parts between the outer walls of the adjusting rod 6 and the sliding guide rod 7 and the connecting hook 9. The sliding guide rod 7 forms a sliding structure between the adjusting rod 6 and the limit frame 8, which is beneficial to the rotation of the adjusting rod 6, and drives the sliding guide rod 7 to perform telescopic movement along the inner wall of the limit frame 8, so as to achieve the effect of synchronously adjusting the air volume in the valve, and play a role in reducing the stability of the working state of the variable air volume Venturi parallel valve caused by long-term driving of the electric push rod.
[0024] Working principle: When using the variable air volume Venturi parallel valve with a one-push-two angle actuator mechanism, when the variable air volume Venturi parallel valve is used daily, in order to improve the linkage of the internal air volume adjustment of the variable air volume Venturi parallel valve, reduce the energy loss driven by the electric push rod, and reduce the stability of the working state of the variable air volume Venturi parallel valve driven by the electric push rod for a long time, when the air volume in the valve needs to be adjusted, the large torque angle actuator body 2 can be opened, and the rotation of the rotating shaft 3 can drive the rotating rod 4 to rotate. The rotation of the rotating rod 4 drives the adjusting rod 6 to rotate effectively along the valve through the connection of the swing rod 5, and drives the sliding guide rod 7 and the telescopic guide rod 12 to slide back and forth synchronously along the inner wall of the limit frame 8 through the connection of the connecting hook 9, so as to achieve the effect of synchronously adjusting the air volume in the valve.
[0025] This is the working principle of the variable air volume Venturi parallel valve with one-push-two angle actuator mechanism.
