Technical Field

The invention belongs to the field of aerostatics, and particularly relates to a valve connecting structure of an aerostat.

Background

The aerostat is a soft structure aircraft which is lighter than air in specific gravity and lifts off by means of buoyancy. The aerostatics utricule is the important structure who holds the buoyancy and rises gaseous, also is the mounting platform of electrical equipment and payload, for maintaining the good pneumatic appearance of utricule, needs carry out pressure control for the pressure differential keeps at certain safe range inside and outside the capsule at whole aerostatics in-process flight. The structural components such as fan, valve all link up with the utricule is inside and outside, call for through-going structural component, and through-going structural component is hard structure, for avoiding the utricule packing to wear out the utricule at in-process such as folding, requires through-going structural component to dismantle on the utricule usually. In addition, the through structural component is required to have good gas tightness at the installation interface on the utricule, and the gas tightness is poor, will lead to the inside buoyancy of utricule to rise the gas leakage and cause the buoyancy loss, or the air leakage is many in the utricule, needs frequently to open the fan and supplies qi, consumes the energy. At present, the common structural form is that two plane flanges are arranged on a through structural part, a through hole is arranged on the capsule body, and two flange edges of the through structural part clamp the capsule body material around the through hole of the capsule body through a fastener. However, in the technical scheme, one end of the inner pressing plate and one end of the fastener are positioned in the capsule body, so that the operation space is limited, and the disassembly and assembly operation of the through structural member is inconvenient.

Disclosure of Invention

The end of the connecting element far away from the bag body is provided with a flanging, so that the pressing of the inner and outer pressing plates and the connecting element is facilitated.

Further, the connecting element is a connecting cylinder, and the connecting element is made of multiple layers of flexible materials. Adopt the connecting cylinder structure, can cooperate with flange structure and through structure spare, strengthen overall connection structure's adaptability. The connecting cylinder is made of multiple layers of flexible materials, so that the rigidity of the connecting element is improved, and the shaking of the through structural member after installation is reduced. Meanwhile, the flexible material is light in weight and does not affect the folding and transportation of the aerostat capsule.

Further, the connecting element is connected with the capsule in a heat sealing mode. The sealing connection mode ensures the sealing performance of the connection part of the connecting element and the capsule body.

Furthermore, a plurality of threaded connecting pieces for fixedly connecting with the outer pressing plate are uniformly arranged on the clamping surface of the inner pressing plate along the circumferential direction. The stability of the threaded connecting piece is guaranteed, meanwhile, the guidance of installation of the connecting structure can be enhanced, and the threaded connecting piece is convenient to install. The threaded connecting piece does not penetrate through the inner pressure plate,

furthermore, the threaded connecting piece does not penetrate through the inner pressing plate, so that the problem that the air tightness is poor due to the fact that the through hole is formed in the inner pressing plate is solved.

Furthermore, the clamping surfaces of the inner pressure plate and the outer pressure plate are respectively provided with a double-layer concave-convex structure matched with each other along the radial direction. The double-layer concave-convex structure enhances the sealing performance between the connecting element and the inner and outer pressing plates on one hand, saves an additional step of glue joint and sealing, and increases the clamping area on the other hand, so that the stress of the turning plate is uniformly dispersed, and the connecting strength of the connecting element and the inner and outer pressing plates is improved.

Further, the radial cross section of the double-layer concave-convex structure is an isosceles trapezoid matched with each other. Further allowing the connecting element to be force dispersed.

Furthermore, the surfaces of the double-layer concave-convex structures on the inner pressing plate and the outer pressing plate are respectively provided with a sealing gasket. The reliable sealing of the inner and outer pressing plates is realized.

Further, the sealing gasket is silica gel or aviation sponge. Silica gel and aviation sponge have good retractility and excellent sealing performance, and simultaneously have the buffering function, and can protect connecting elements in the installation process.

The invention has the following advantages:

1. according to the invention, the connecting element is arranged on the capsule body of the aerostat, and the flanging used for being pressed with the inner and outer pressing plates is arranged at one end of the connecting element, so that the disassembly and assembly operation of the through structural member outside the capsule body is realized, the operation space is enlarged, the disassembly and assembly operation is convenient, the pressing of the inner and outer pressing plates and the connecting element is tighter due to the flanging, and the integrity of the connecting structure is enhanced.

2. The connecting element is made of multiple layers of flexible materials, can be spliced with the aerostat capsule into a whole in a heat seal connection mode, and is reliable in sealing performance. The weight is light, and rigidity is strong, can reduce the rocking of installation back through structure spare, does not influence the folding transportation of aerostatics utricule simultaneously.

3. The outer pressing plate is arranged on the through structural member, so that the installation process is simplified, and meanwhile, the clamping surface of the inner pressing plate matched with the outer pressing plate is fixedly connected with the threaded connecting piece, so that the installation guidance of the connecting structure is enhanced, and the installation efficiency is integrally improved. The threaded connection piece does not penetrate through the inner pressing plate, and the problem that the air tightness is poor due to the fact that the through hole is formed in the inner pressing plate is avoided.

4. The double-layer concave-convex structure and the sealing gasket arranged on the surface of the concave-convex structure can ensure the sealing property between the connecting element and the inner and outer pressing plates without additional adhesive sealing. Meanwhile, the clamping area is increased, and the connecting strength of the connecting element and the inner and outer pressing plates is improved.
