Problems solved by technology

The purpose of this type of jet mixer is to heat the liquid with steam, and the nozzle is a multi-circular small hole structure, which cannot be used for the aspirator and mixer with ejection effect.
[0017] The patent with the authorized notification number CN26677021Y discloses a jet mixer, which is similar to a nozzle in the form of a shower head in a bathroom. The purpose is to solve the problem of high temperature thermal protection, and it cannot be used for air extractors and mixers with ejector functions.
[0018] The patent with the authorized notification number CN2096009U discloses a steam condensate recovery injector. The converging conical nozzle is a mixing injector for steam and water in the boiler steam condensate recovery device. The purpose is to mix and solve the problem of steam Blocking problem, can not be used for jet aspirator and mixer with ejection effect

Abstract

The invention provides a subsonic velocity chrysanthemum-shaped nozzle and a water injecting and air pumping device, or an injection type mixer, or a steam injection pressurizing device or a steam injection water heater and other devices equipped with the nozzle. The chrysanthemum-shaped nozzle comprises an inlet section, an outlet section and an extending section which are sequentially connected to form a complete subsonic velocity chrysanthemum-shaped nozzle structure. The water injecting and air pumping device equipped with the subsonic velocity chrysanthemum-shaped nozzle comprises a 1) main stream inlet section, 2) the chrysanthemum-shaped nozzle, 3) a suction chamber and a secondary stream inlet connected with the suction chamber, 4) a diffusion chamber mixing section, 5) a throat part of a diffusion chamber, and 6) a diffusion section of the diffusion chamber. Compared with the existing a large amount of shrinkage tapered nozzles or straight tube shaped nozzles, and the water injecting and air pumping device and other devices equipped with the nozzle. According to the device, the injection coefficients are fundamentally greatly increased according to the mechanism; the working efficiency and adjustable main and secondary stream mixing ratio are greatly increased.
