But the nozzle of existing Jet injector all is arranged in the pipeline usually, all has honeycomb duct on the direction opposite with the injection direction of nozzle and makes its structure relative complex, becomes production. art complicated, and its out-of-shape, stores and carry all inconvenient.This document on the one hand can be with reference to following patent: application number is 200580025646.4 Chinese patent, discloses a kind of jet pump; Application number is 200510041417.3 Chinese invention patent, discloses a kind of Pneumatic injection pump; Application number is 201120158940.5 Chinese invention patent, discloses a kind of jet injector with high efficiency; Application number is 200820199215.0 Chinese utility model patent, discloses a kind of plain type Jet injector.
Summary of the invention
The utility model provides a kind of simple in structure to deficiency of the prior art, advantages of small volume, and technology is simple, and is easy to carry, the Jet injector of being convenient to store.
In order to solve the problems of the technologies described above; The utility model is able to solve through following technical proposals: a kind of Jet injector; Comprise suction tude with suction port and air outlet; The fluid passage that is used for draw fluid, said fluid passage longshore current body flow direction comprises contraction section, larynx section and diffuser successively; The air outlet of said suction tude is over against said contraction section setting and its area area less than the inlet of said contraction section, and the distance between the inlet of said air outlet and said contraction section is controlled between 3 millimeters to 4 millimeters so that have between the two and be convenient to the gap that fluid gets into said contraction section.
The nozzle rear of the utility model need not conduit; Thereby make by draw fluid through the vacuum that the gap location between suction tude and the fluid passage forms and directly to get into the purpose that the fluid passage reaches draw fluid from this gap; And the distance between the inlet of air outlet and contraction section to be controlled at 3 millimeters to 4 millimeters be because if distance is excessive, then suction effect reduces, if distance is too small; Then might cause bigger object can't get in the fluid passage, result in blockage.Therefore, compared with prior art, the utlity model has simple in structure, advantages of small volume, technology is simple, processing cost is low, and is easy to carry, the advantage of being convenient to store.
In order to obtain better technique effect, further technical measures also comprise:
The outlet side of above-mentioned suction tude has a curved part and a straight pipe portion, and the central axis of said air outlet is parallel to the central axis of said straight pipe portion, and the tube wall of said fluid passage and said straight pipe portion links together.This structure has further been dwindled the length of the utility model, and structure is compact more, and volume is smaller and more exquisite, and the outlet of suction port and fluid passage is positioned at same direction, and is more convenient to operate.
As preferably, the tube wall of above-mentioned fluid passage and said straight pipe portion is one-body molded to link together.Integrated mode makes course of working simpler, and processing cost is lower.
As another preferred version, above-mentioned fluid passage is connected on the said straight pipe portion through link is removable.Fluid passage and suction tude separate machined, only need be assembled together in use get final product, and if one of them parts be damaged, only need its broken parts of replacing to get final product, reduced maintenance cost; On the other hand, go back the adjustable clearance size, under the different fluids environment, adopt gap length with its adaptation.
Further improve, place, above-mentioned air outlet is provided with along the diminishing nozzle of air current flow direction cross section.Nozzle can be accelerated airspeed, makes suction effect better, and efficient is higher.
Further improve, above-mentioned suction port place is connected with the flexible pipe connection adaptor.The flexible pipe connection adaptor is used to connect the flexible pipe of introducing high pressure draught.
The installation of flexible pipe for ease, the inlet end of above-mentioned suction tude is bent to a lateral bending, and the central axis of the central axis of suction tude and said fluid passage is positioned on the same plane.
Compared with prior art, the utlity model has following beneficial effect: simple in structure, advantages of small volume, technology is simple, and processing cost is low, and is easy to carry, is convenient to storage.
