Embodiment
The utility model is further described below by non-limiting embodiment and with reference to accompanying drawing：
As shown in drawings, a kind of pipeline structure of fluid flow device, it include by be linked in sequence successively No. 1 arm pipe 1,
The U-tube section for the " U "-shaped shape that 2, No. 3 arm pipes 3 of No. 2 arm pipes are formed, the arm pipe 2,3 of No. 1 arm pipe 1, the 2 arm pipe 3 are
Circular stainless steel tube.No. 1 arm pipe 1 has certain angle with horizontal plane, and No. 1 arm pipe 1 is inclined relative to horizontal and set upwards
Put, have certain angle between No. 2 arm pipes 2 and No. 1 arm pipe 1, and No. 2 arm pipes 2 tilt upward setting relative to No. 1 arm pipe 1,
There is certain angle between No. 3 arm pipes 3 and No. 2 arm pipes 2, and No. 3 arm pipes 3 tilt upward setting, i.e. U relative to No. 2 arm pipes 2
