Abstract
The invention relates to the field of metal hoses, in particular to a natural gas conveying anti-explosion metal hose, and aims to solve the problems that an existing metal hose is low in strength andhigh in flow speed. The natural gas conveying anti-explosion metal hose comprises a metal hose body, wherein a fixing set of a flange and a loose flange is arranged on one side of the metal hose body; a butt welding flange is arranged on the other side of the metal hose and used for fixing; the metal hose is covered with a steel belt of a multi-layer structure; the two ends of the metal hose andthe two ends of the steel belt are fixed through cooperation of metal nipples and pressing clamp rings; and the metal hose is wound with a reinforcing ring. According to the natural gas conveying anti-explosion metal hose, the structure of an existing metal hose is optimized. The reinforcing ring is designed in the metal hose, so that the strength of the metal hose is improved, and the double anti-explosion effect of the metal hose is achieved. Meanwhile, the structure that the an existing metal hose is wound with a steel belt is optimized, all layers of the steel belt with which the outer layer of a corrugated pipe is wrapped are in staggered contact through the change of the winding sequence, and generation of friction static electricity is restrained.
