<P>PROBLEM TO BE SOLVED: To provide a venturi type mixing device having a simple structure, and using a venturi tube applicable even to a fluid having flammability and corrosiveness. <P>SOLUTION: In this venturi type fluid mixing device 1, a venturi tube 3 is arranged in a passage of a fluid, a second fluid is supplied to a first fluid supplied from the upstream side of the venturi tube 3 at a throat part of the venturi tube or on the upstream side thereof, and thereby both the fluids are mixed. The venturi type mixing device includes: a movable body 5 arranged in the passage and movable along the passage direction and having a surface of which the cross-sectional area varies along the passage direction; a cylinder 7 in which a part of the movable body 5 is movably inserted and a working fluid for operating the movable body 5 is stored; and a pressure adjustment means to adjust the pressure of the working fluid in the cylinder 7 based on differential pressure between the fluid pressure on the upstream side of the venturi tube 3 and the fluid pressure at the throat part of the venturi tube. <P>COPYRIGHT: (C)2012,JPO&INPIT |
