Abstract

The invention discloses a winding linear structure of an air respirator. The winding linear structure comprises a bottle body and a linear winding layer, wherein the linear winding layer is arranged outside the bottle body; the linear winding layer comprises a first winding layer, a second winding layer, a third winding layer, a fourth winding layer, a fifth winding layer, a sixth winding layer, a seventh winding layer and an eighth winding layer which are successively distributed from interior to exterior, the first winding layer is formed by combining five layers of linear fiber layers subjected to hoop winding, and the second winding layer and the seventh winding layer are respectively 15-degree longitudinal linear fiber layers; the third winding layer, the sixth winding layer and the eighth winding layer are formed by combining two layers of liner fiber layers subjected to hoop winding, the fourth winding layer is a 70-degree spiral winding linear fiber layer, and the fifth winding layer is a 23-degree longitudinal winding liner fiber layer. The winding linear structure provided by the invention has the advantages that the problem of force-circulation capacity supported by a composite cylinder is solved, the high pressure circulation under test pressure being 45MPa is realized, and an EU standard requirement is met.

Description

technical field [0001] The invention relates to the field of manufacturing composite gas cylinders, in particular to a winding wire structure for an air respirator. Background technique [0002] The existing air respirator bottle body has low product strength and low working pressure, and the number of pressure alternating cycle tests can only be carried out about 3000 times under the condition of 2-45Mpa, and the service life is relatively short. Contents of the invention [0003] The object of the present invention is to provide a winding wire structure for an air respirator. [0004] The invention aims to solve the problems of low product strength, low working pressure and short service life of the existing air respirator bottle body. [0005] The technical solution of the present invention is: an air respirator winding wire structure, including a bottle body and a wire winding layer, the wire winding layer is arranged on the outside of the bottle body, and the wire wi...
