STRUCTURE OF HOSE

STRUCTURE OF HOSE

A hose includes at least an inner-layer tubular member, an intermediate laye r, and an outer-layer tubular member. Both the inner-layer tubular member and t he outer-layer tubular member are made of plastics. The intermediate layer is formed by wrapping a net. An outer surface of the intermediate la...

Zusammenfassung:A hose includes at least an inner-layer tubular member, an intermediate laye r, and an outer-layer tubular member. Both the inner-layer tubular member and t he outer-layer tubular member are made of plastics. The intermediate layer is formed by wrapping a net. An outer surface of the intermediate layer is provided with a helical structure made of plastics and the outer-layer tubular member encloses the helical structure. The helical structure has a mechanical strength greater than the outer-layer tubular member. Since both the helical structur e and the outer-layer tubular member are similarly made of plastics, the bonding strength therebetween can be enhanced. When the hose is subjected to bending, the helical structure helps to prevent the hose from being compressed and deformed, thereby maintaining the inside diameter of the hose to ensure smooth flow of liquid or gas through the hose.
