Embodiment Construction

[0019] An aerostat capsule inflation and deflation all-in-one machine, such as figure 1 As shown, it includes a protective cover 1; a valve seat 2; a valve core 3; a hinge device 4; a bearing member 5; an elastic device 6; a bearing plate 7;

[0020] The valve seat 2 is connected with the capsule body, the valve core 3 is located outside the capsule body, and the protective cover 1 is located in the inner cavity of the capsule body, and the protective cover has sealing performance. During installation, the connection between the valve seat 2 and the capsule requires sealing. The fixed end of the hinge device 4 is installed on the valve seat 2, the movable end is connected with the inner side of the valve core 3, one end of the force-bearing member 5 is connected with the valve seat, and the other end is fixed to the force-bearing plate, and the force-bearing plate 7 is also equipped with an electric pusher The rod 10 is used to push the spool 3 away. One end of the elastic d...

Abstract

The invention belongs to the field of aerostats and discloses an aerostat bag body inflating and deflating integrated machine. A draught fan and an air valve are installed in a protecting cover, and the protecting cover has the sealing performance. When the bag body pressure is lower than a set threshold value, the draught fan is automatically opened, the air valve is automatically opened at the same time, the inflating and deflating integrated machine supplements air into a bag body till the bag body pressure restores to the set threshold value, and the draught fan and the air valve are automatically closed; when the bag body pressure is higher than the set threshold value, the air valve is automatically opened, the bag body performs air exhausting till the bag body pressure restores to the set threshold value, and the air valve is automatically closed; and the problems of draught fan gas leaking and low efficiency are solved, the installing hole number and the installing area of thebag body are reduced, the integrated machine has both the inflating and deflating functions, installing is easy and the manufacturing cost is low.

Description

technical field [0001] The invention belongs to the field of aerostats, in particular to an aerostat capsule inflation and deflation integrated machine. Background technique [0002] An aerostat is an aircraft whose specific gravity is lighter than air and which relies on atmospheric buoyancy to lift into the air. It has the advantages of long blanking time, strong weather resistance, good economical use, safety and reliability, etc., and has a wide range of military and civilian uses. [0003] Under different lift-off heights, the aerostat usually adopts the method of automatically filling and discharging air to adjust its internal pressure, so as to ensure the aerodynamic shape and stiffness of the capsule, and at the same time play a role in protecting the capsule. The commonly used method at present is to arrange two mounting holes on the capsule body, and install the blower fan and the air valve respectively. The fan supplements the air in the capsule, increases the p...
