Embodiment 1

[0030] Example 1 please refer to figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 and Figure 6 One embodiment shown is a low-leakage aircraft ground air-conditioning air supply hose, including a molded hose 9, and the molded hose 9 includes several connecting hoses 1, and the connecting hose 1 includes two inner adhesive plaster pieces 101 and two edging strips 104, the two sides of each inner rubber cloth sheet 101 are provided with connecting edge strips 2 and sewing edge strips 3, and the two connecting edge strips 2 are pasted and connected with the inner surfaces of the two inner adhesive cloth sheets 101 respectively to form an inner Adhesive tube, each inner adhesive sheet 101 is provided with an insulating layer adhesive sheet 103, and each insulating layer adhesive sheet 103 is provided with an outer adhesive sheet 102, two sewing edge strips 3 and two outer adhesive sheet sheets 102 One end of each is fixedly connected to the inside of the two edging bel...

Embodiment 2

[0032] On the basis of the above examples, please refer to Example 2 Figure 6 An embodiment shown, the two ends of the connecting hose 1 are all sewn with adhesive plaster sheets, a zipper 8, a first buckle suede surface 4 and a second buckle hook surface 7 are sewn on one adhesive plaster sheet, and the other adhesive plaster The sheet is sewn with a zipper 8, a first buckle hook surface 5 and a second buckle suede surface 6, and the first buckle suede surface 4 and the second buckle suede surface 6 are double-layered fabrics that are folded back. The connecting parts of the two connected hoses 1 adopt two buckle cloth loops with opposite overlapping directions, and there are two reversely pasted buckles on the outside of the zipper 8 to block the leakage from the zipper 8 The cold air and hot air can effectively reduce the leakage of the connection parts.

Embodiment 3

[0034] On the basis of the above examples, please refer to Example 3 figure 1 and Figure 4 In one embodiment shown, the forming hose 9 is in the shape of a large arc, the inner adhesive sheet 101, the outer adhesive sheet 102 and the insulation layer adhesive sheet 103 are all in the shape of an arc, and the forming hose 9 is in the shape of a large arc, effectively avoiding This prevents the formation of "dead folds" due to local bending during the air supply process of the connecting hose 1, and reduces the air supply resistance of the connecting hose 1.

Abstract

The invention discloses a low-leakage airplane ground air conditioner air supply hose. The low-leakage airplane ground air conditioner air supply hose comprises a formed hose body, the formed hose body comprises a plurality of connecting hoses, each connecting hose comprises two inner adhesive tape pieces and two edge covering belts, and the two sides of each inner adhesive tape piece are providedwith a connecting edge strip and a sewing edge strip; the two connecting edge strips are connected with the inner faces of the two inner adhesive tape pieces in an adhering mode to form an inner adhesive tape barrel, a heat preservation layer adhesive tape piece is arranged outside each inner adhesive tape piece, an outer adhesive tape piece is arranged outside each heat preservation layer adhesive tape piece, and the ends of the two sewing edge strips and the ends of the two outer adhesive tape pieces are fixedly connected to the interiors of the two edge covering belts respectively. According to the low-leakage airplane ground air conditioner air supply hose, the joint of the inner adhesive tape cylinder formed by the two inner adhesive tape pieces is welded through hot air or bonded through an adhesive, so that the inner adhesive tape cylinder is not provided with a sewn needle hole, only a small number of sewn needle holes are formed in the zipper parts sewn at the two ends, and the leakage amount of air flowing through the sewn needle holes is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of aircraft ground air-conditioning equipment, in particular to a low-leakage aircraft ground air-conditioning air supply hose. Background technique [0002] The aircraft ground air conditioning unit refers to the air conditioning equipment that provides filtered, pressurized, dehumidified and dehumidified (or heated) fresh air for the aircraft parked on the ground. The aircraft ground air conditioner is mainly used in the process of delivering the processed fresh air. Air supply hose for delivery. [0003] Generally, the length of the air-conditioning air supply hose on the ground of the aircraft ranges from 10 to 40 meters. Due to the long length and heavy weight, it is manufactured in sections and connected in multiple sections. Each set of hoses consists of 4 to 8 sections. , every two sections of hose are connected by zipper and buckle (Velcro). The existing air duct is sewn in multiple layers, and the...
