摘要： The present disclosure provides an exhaust assembly for an aerostat, including a valve base (2) provided with a valve port (1), and a valve cover (3) that selectively covers the valve port (1), and further including: a motor driving mechanism and a transmission mechanism that are arranged on the valve base (2). The motor driving mechanism propels the transmission mechanism to drive the valve cover (3) to selectively cover the valve port (1). When the valve cover (3) is in a position where the valve port (1) is open, the valve cover (3) is arranged at an angle with respect to a plane at which the valve port (1) is located. A purpose of the present disclosure is to provide the exhaust assembly that is for an aerostat and whose exhausting pressure can be flexibly adjusted, and an aerostat provided with the exhaust assembly.
