Adjustable steam-water heat exchange pump

The utility model relates to an adjustable steam-water heat exchange pump, belonging to the technical field of a steam-water heat exchange device. At present, the clearance between the nozzle of a steam-water heat exchange pump used in a heat supply system and the inlet of a mixing chamber is fixed, so that the flow quantity of the water and the steam-water ratio can not be changed, which can only work under the special operating condition, and oscillation and spraying sound can be generated easily. The essential technical proposal of the utility model is that a connecting pipe I 1, a housing 2, a connecting pipe II 4, a connecting pipe III 7 and an angle pipe 9 are connected orderly. The housing 2 is provided with a nozzle 3 with a rectifier tank 18. A mixing diffusion chamber 5 whose one end is provided with a rectifier tank 17 is arranged in the connecting pipe II 4 and the connecting pipe III 7. The other end of the mixing diffusion chamber 5 is provided with a spring 8. A screw bolt 10 with a seat 16 which is inserted into the mixing diffusion chamber 5 is arranged on the angle pipe 9. The adjustable steam-water heat exchange pump has the advantages that the adjustable steam-water heat exchange pump uses steam as the dynamic force to convey water, and the water is heated and diffused in the conveying process, which overcomes the common oscillation and spraying sound because of improper steam-water ratio.
