The invention provides an air volume control module, a ventilation system and a biosafety laboratory, the air volume control module comprises a first pipe section and an electric air valve, the electric air valve comprises an air valve driving part and a valve plate, the valve plate is rotatably mounted in the first pipe section, and the air valve driving part drives the valve plate to rotate; the valve plate is hinged to the first pipe section through the first shaft end and the second shaft end. A first shaft hole in running fit with the first shaft end and a second shaft hole in running fit with the second shaft end are formed in the peripheral wall of the first pipe section, the second shaft hole penetrates through the peripheral wall of the first pipe section in the radial direction, and a driving shaft of the air valve driving part is connected with the second shaft end; a first sealing cover is further arranged outside the peripheral wall of the first pipe section and covers the second shaft hole, the air valve driving piece is located in the first sealing cover, and the first sealing cover is connected with the outer surface of the peripheral wall of the first pipe section in a sealed mode. The air volume control module can ensure the air tightness of a ventilation system, and further ensure the detection precision of an air speed sensor and the control precision of the system.
本发明提供一种风量控制模块、通风系统和生物安全实验室,风量控制模块包括第一管段和电动风阀,电动风阀包括风阀驱动件和阀板,阀板可转动地安装在第一管段内,风阀驱动件驱动阀板转动;阀板通过第一轴端和第二轴端铰接在第一管段上;第一管段的周壁上开设有与第一轴端转动配合的第一轴孔以及与第二轴端转动配合的第二轴孔,第二轴孔沿径向贯穿第一管段的周壁,风阀驱动件的驱动轴与第二轴端连接;第一管段的周壁的外部还设置有第一密封盖,第一密封盖覆盖第二轴孔,风阀驱动件位于第一密封盖内,第一密封盖与第一管段的周壁的外表面密封连接。该风量控制模块能够保证通风系统气密性,进而保证风速传感器检测精度和系统控制精度。
