The flow guiding assembly includes an actuating motor, a connecting bracket, a flow guiding plate A, a flow guiding plate B, a hinged connecting rod A, a hinged connecting rod B, an actuating cylinder A, and a connecting sleeve A. The connecting bracket is rotatably installed on the tee pipe body, the actuating motor is installed on the tee pipe body, the output shaft of the actuating motor is installed on the connecting bracket, the flow guiding plate A and the flow guiding plate B are rotatably installed on the connecting bracket. The flow guiding plate A is hingedly installed at one end of the hinged connecting rod A, the other end of the hinged connecting rod A is hingedly installed on the connecting sleeve A, the flow guiding plate B is hingedly installed at one end of the hinged connecting rod B, the other end of the hinged connecting rod B is hingedly installed on the connecting sleeve A, the connecting sleeve A is installed on the output shaft of the actuating cylinder A, and the actuating cylinder A is installed on the connecting bracket.

[0006] Furthermore, the included angle change range between the flow guiding plate A and the flow guiding plate B is 15 degrees - 30 degrees to avoid sudden changes in flow velocity.

[0007] Furthermore, the tee pipe body is provided with a pipe body A, a pipe body B, and a pipe body C. The center line of the pipe body B or the pipe body C is distributed at an angle of 30 degrees - 45 degrees with the center line of the pipe body A.

[0008] Furthermore, the ratio of the radius on the center line of the three-way connection of the pipe body A, pipe body B, and pipe body C to the pipe diameter of the pipe body B or pipe body C is greater than or equal to 1.5.

[0009] Furthermore, the three-way pipe body is manufactured by a hydroforming process.

[0010] Furthermore, the inner wall of the three-way pipe body is polished or lined with a flexible material.

[0011] Furthermore, the flexible lining material is a PE material.

[0012] Furthermore, the pipe wall roughness of the three-way pipe body is ≤ 0.15 mm.

[0014] Furthermore, the polymer is polyethylene oxide.

[0015] The advantages of the present invention are as follows: 1. The gas flow enters through the pipe body A in the three-way pipe body, and the gas is split through the pipe body B and pipe body C in the three-way pipe body and then flows out; when the air flow passes through the deflector A or deflector B, due to the decrease in the space between the deflector A or deflector B and the pipe body A, when the fluid flows through the reduced cross-section, the flow velocity of the air flow passing through the pipe body B or pipe body C is increased, thereby reducing the pressure loss; at the same time, the actuating motor is started, the actuating motor drives the connecting bracket to rotate, the connecting bracket drives the deflector A and deflector B to rotate, so that the cross-sectional area between the deflector A and the pipe body A or the cross-sectional area between the deflector B and the pipe body A changes, and the flow velocity of the air flow passing through the pipe body B or pipe body C changes. When the angle between the deflector A and the deflector B is fixed, if the cross-sectional area between the deflector A and the pipe body A increases, the cross-sectional area between the deflector B and the pipe body A decreases, and vice versa. When the cross-sectional area between the deflector A and the pipe body A increases, the flow velocity of the air flow passing through the pipe body B becomes relatively smaller; when the cross-sectional area between the deflector A and the pipe body A decreases, the flow velocity of the air flow passing through the pipe body B becomes relatively larger; similarly, when the cross-sectional area between the deflector B and the pipe body A increases, the flow velocity of the air flow passing through the pipe body C becomes relatively smaller; when the cross-sectional area between the deflector B and the pipe body A decreases, the flow velocity of the air flow passing through the pipe body C becomes relatively larger; at the same time, the actuating cylinder A is started, and the actuating cylinder A drives the articulated connecting rod A and the articulated connecting rod B to move through the connecting sleeve A, so that the angle between the deflector A and the deflector B changes; 2. Start the actuating cylinder B, and the actuating cylinder B drives the end plate B to rotate through the connecting rod B, so that the end plate B changes the cross-sectional area of the three-way pipe body, thereby adjusting the ventilation volume.

One end of the deflector A 2-3 is hingedly installed on one end of the hinged connecting rod A 2-5, the other end of the hinged connecting rod A 2-5 is hingedly installed on the connecting sleeve A 2-8, one end of the deflector B 2-4 is hingedly installed on one end of the hinged connecting rod B 2-6, the other end of the hinged connecting rod B 2-6 is hingedly installed on the connecting sleeve A 2-8, the connecting sleeve A 2-8 is installed on the output shaft of the actuating cylinder A 2-7, and the actuating cylinder A 2-7 is installed on the connecting bracket 2-2. With such a setting, the gas flow enters through the pipe A in the tee pipe body 1, and the gas is divided through the pipe B and the pipe C in the tee pipe body 1 and then the air flow flows out. When the air flow passes through the deflector A 2-3 or the deflector B 2-4, since the cross-section between the deflector A 2-3 or the deflector B 2-4 and the pipe A becomes smaller, when the fluid flows through the reduced cross-section, the flow rate of the air flow passing through the pipe B or the pipe C is increased, thus realizing the reduction of pressure loss. At the same time, start the actuating motor 2-1, the actuating motor 2-1 drives the connecting bracket 2-2 to rotate, the connecting bracket 2-2 drives the deflector A 2-3 and the deflector B 2-4 to rotate, so that the cross-sectional area between the deflector A 2-3 and the pipe A or the cross-sectional area between the deflector B 2-4 and the pipe A changes, and the flow rate of the air flow passing through the pipe B or the pipe C changes. When the included angle between the deflector A 2-3 and the deflector B 2-4 is fixed, if the cross-sectional area between the deflector A 2-3 and the pipe A increases, the cross-sectional area between the deflector B 2-4 and the pipe A decreases, and vice versa. When the cross-sectional area between the deflector A 2-3 and the pipe A increases, the flow rate of the air flow passing through the pipe B becomes relatively smaller; when the cross-sectional area between the deflector A 2-3 and the pipe A decreases, the flow rate of the air flow passing through the pipe B increases relatively. Similarly, when the cross-sectional area between the deflector B 2-4 and the pipe A increases, the flow rate of the air flow passing through the pipe C becomes relatively smaller; when the cross-sectional area between the deflector B 2-4 and the pipe A decreases, the flow rate of the air flow passing through the pipe C increases relatively.

The end plate B3-3 is fixedly installed on the connecting rod B3-2. With such a setting, when the actuating cylinder B3-1 is started, the actuating cylinder B3-1 drives the end plate B3-3 to rotate through the connecting rod B3-2, so that the end plate B3-3 changes, causing the cross-sectional area of the three-way pipe body 1 to change, thereby adjusting the ventilation volume.

[0021] Embodiment 3 As Figures 1-8 shown, the included angle range of the deflector A2-3 and the deflector B2-4 is 15 degrees - 30 degrees to avoid sudden changes in flow velocity.

[0023] Among them, the ratio of the radius on the center line of the three-way of the pipe body A, the pipe body B, and the pipe body C to the pipe diameter of the pipe body B or the pipe body C is greater than or equal to 1.5.

[0024] Among them, the three-way pipe body 1 is manufactured by a hydroforming process.
