Embodiment 1
[0028] Embodiment 1 shunt adjustment type
[0029] exist Figure 5 with Image 6 In the present invention, the main body of the device for evenly sending and returning air through the long air duct is composed of a long air duct and a bypass branch pipe. The valve bodies of the three ventilation valves 4 are connected, and the valve bodies are composed of interconnected main air pipes 1 and straight-through branch pipe interfaces 2. The feature is that the three ventilation valves 4 are served by energy-saving air volume diversion three-way regulating valves 6, so The above-mentioned long air pipe is composed of a group of several valve body cross-sectional area sizes that are gradually reduced according to the ratio of the rated air flow volume of each stage. The main body of the regulating diversion type energy-saving air volume diversion three-way regulating valve 6 is composed of a main air pipe 1, a straight-through branch pipe interface 2 and a bypass branch pipe inter...
Embodiment 2
[0031] Embodiment 2 shunt rated type
[0032] exist Figure 7 with Figure 8 In the present invention, the main body of the device for evenly sending and returning air through the long air pipe is composed of the long air pipe and the bypass branch pipe connection 3, the long air pipe is formed by connecting the valve bodies of several three ventilation valves 4, and the valve bodies are interconnected The main air duct 1 and the straight branch pipe interface 2 are characterized in that the three ventilation valves 4 are served by rated split-type improved three-ventilation valves 23, and several rated split-type improved three-ventilated valves are set on the long air duct. The cross-sectional size of the valve body of the ventilation valve 23 is reduced step by step according to the ratio of the rated split air volume of each stage. On the inner surface of the main air duct 1 of the valve 4, one end is connected to the bypass branch pipe interface 3, the cross-sectional a...
