[0016] The utility model will be described in more detail below in connection with the drawings and examples.

[0017] The utility model discloses a kind of jet flow device, as shown in combination Figures 1 to 4 It includes three-way pipe 1, import pipe 2 and outlet pipe 3, outlet pipe 3 and import pipe 2 are inserted in the front and rear two ends of three-way pipe 1 respectively, import pipe 2 is inserted into one end of three-way pipe 1 and forms narrow mouth end 20, the inner diameter of narrow mouth end 20 is less than the pipe body inner diameter of import pipe 2, three-way pipe 1 includes intermediate pipe head 10, intermediate pipe head 10 is aligned with the side of narrow mouth end 20, the inside of import pipe 2 is equipped with cross flow guide plate 4, cross flow guide plate 4 is located at the entrance of narrow mouth end 20, and cross flow guide plate 4 is coaxially arranged with narrow mouth end 20, the blade 40 of cross flow guide plate 4 is inclined to the axis of cross flow guide plate 4 by preset angle.

[0018] In the structure, the outlet pipe 3 and the inlet pipe 2 are respectively inserted into the front and rear ends of the three-way pipe 1, the inlet pipe 2 is used for connecting the uplink pipeline, the outlet pipe 3 is used for connecting the downlink pipeline, and the middle pipe head 10 is used for connecting the fluid pipeline to be introduced. Under the fluid pressure applied to the uplink pipeline, the pressure of the fluid is increased when the fluid passes through the narrow end 20, and the outlet position of the middle pipe head 10 generates negative pressure in the process that the fluid passes through the narrow end 20 and enters the outlet pipe 3, so that the fluid in the middle pipe head 10 is sucked into the outlet pipe 3 for fluid mixing.
