Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Attached drawing 1-4 is please referred to, the utility model provides a kind of technical solution:
A kind of pressure swing type steam circulation system, including regulating valve B, heating equipment C, pressure limiting device Db, steam-water separation
