An overpressure and deformation control device for an umbrella opening type airship gasbag comprises a horizontal plane parallelogram deployment mechanism, a vertical plane parallelogram deployment mechanism, an electric capstan (3), a set of pulley assembly and a steel cable (5). The horizontal plane parallelogram deployment mechanism comprises four truss type rods A (1), and the vertical plane parallelogram deployment mechanism comprises four truss type rods B (2). The overpressure and deformation control device has the advantages that in the flight process of an umbrella opening type airship, the shape and volume variation of the umbrella opening type gasbag is actively controlled, the influence of atmospheric characteristic variation on gasbag overpressure is eliminated, the controllable and basically-constant gasbag overpressure is achieved, and the rigid demand of an umbrella opening type gasbag body is met.
