Specific embodiment
As Figure 1-3, a kind of fuel gas transmission of the utility model metal hose, including the rigid curved section 2 and soft being connected
Property compensator section 1；The end of described rigid curved section 2 is provided with the first joint 3, and the end of described flexible compensation section 1 is provided with second and connects
4, described second joint 4 is provided with dust guard 5.
Rigid curved section 2 described in the utility model is stainless steel three-dimensional bending tube, described three-dimensional bending tube and flexible compensation section 1 and
First joint 3 is fixedly connected by welding manner.Described flexible compensation section 1 includes bellows 11, is wrapped on bellows 11
Wire sets 13, pine are enclosed within the helical wound ribbon 14 outside wire sets 13；Described bellows 11 is ring-like u-shaped ripple stainless steel ripple
Pipe, end is fixedly connected with adapter by welding manner；Ring 15 and bellows 11 end are passed through in described wire sets 13 end
Adapter is fixedly connected using welding manner；Described helical wound ribbon 14 end is adopted by the adapter of grommet 16 and bellows 11 end
It is fixedly connected with welding manner.Described first joint 3 is nipple or bump joint；Described second joint 4 is nipple
