The specific embodiment
In conjunction with the accompanying drawings and embodiments the utility model is described in further detail now, these accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
As Fig. 1, Fig. 2, shown in Fig. 3, the two entrance medium injection devices of screw-in, comprise body 1 and threaded nozzle 2, body 1 is provided with vacuum chamber 3, screwed hole 4, Venturi tube 5 and two two tangential arms 6, wherein the coaxial connection of screwed hole 4 and Venturi tube 5 is at vacuum chamber two ends, nozzle 2 is sheathed to be connected in nozzle bore 4, in 3 side weeks of vacuum chamber, tangential arm 6 is tangent with the side week of vacuum chamber 3, two tangential arms 6 are the centrosymmetric structures centered by Venturi tube 5 axis, then the steam simultaneously entering in vacuum chamber 3 from two tangential arms 6 can mix along vacuum chamber 3 inwall rotations, extended like this residence time of steam at vacuum chamber 3, and two strands of steam of rotation can better mix.
Threaded nozzle 2 is provided with the flat pipe portion 7 that is positioned at screwed hole 4 outsides and the tip 8 that is positioned at vacuum chamber 3, the structural design of tip 8 can guarantee the air in vacuum chamber 3, fluid media (medium) and steam etc. flow to Venturi tube 5 smoothly, and can not produce inhibition, tip 8 ends are provided with and the spout 9 of putting down pipe portion 7 inner chambers and being communicated with, the inner diameter of flat pipe portion 7 is far longer than the inner diameter of spout 9, contribute to like this to improve the spouting velocity of fluid media (medium) in threaded nozzle 2, screwed hole 4 internal thread connecting thread nozzles 2, flat pipe portion 7 outsides are with external screw thread, screwed hole 4 inwalls are with internal thread, internal thread mates with external thread structure, threaded nozzle 2 can move at screwed hole 4 inside spins along its axis, rotation threaded nozzle 2, threaded nozzle 2 just can move forward and backward along its axis in screwed hole 4, there is crosspoint 14 with tangential arm 6 axis in threaded nozzle 2 axis, spout 9 be positioned at 14 left and right sides, 14Shang Huo crosspoint, crosspoint threaded nozzle 2 axis on, when spout 9 positions of the threaded nozzle 2 that can move and the relative position in crosspoint 14 change, the fluid media (medium) of ejection is also different to the vacuum swabbing action in vacuum chamber 3 at a high speed, therefore, by regulating the vacuum of the adjusting vacuum chamber 3 that the relative position in spout 9 and crosspoint 14 just can be relative.
Venturi tube 5 is provided with compression section 10, larynx section 11 and diffuser 12 successively along its axis, compression section 10 vacuum chamber 3 that is tightly connected, compression section 10 and vacuum chamber 3 junction internal diameters are greater than the junction internal diameter of itself and larynx section 11, and diffuser 12 free end internal diameters are greater than the junction internal diameter of itself and larynx section 11.Fluid media (medium) 10 enters Venturi tube 5 with certain speed from compression section, because the compression section 10 cross section radiuses of air stream warp dwindle gradually, the flow velocity of fluid media (medium) increases thereupon, while arriving larynx section 11, air velocity is maximum, from Bernoulli equation, air velocity is inversely proportional to air pressure herein, the air pressure that is larynx section 11 is minimum, the direction top rail section radius that air-flow is flowed through at diffuser 12 becomes large gradually, fluid media (medium) flow velocity diminish gradually slow down and, steam and air that last fluid media (medium) drives flow out Venturi tube 5, Venturi tube 5 has guaranteed fluid media (medium), steam and air all can not flow backwards as in vacuum chamber 3.
Screwed hole 4 free ends, Venturi tube 5 free ends, two tangential arm 6 free ends and flat tube section 7 free ends are equipped with being tightly connected along 13 of turning up along its circumferential edge, and this kind of structure contributes to its be tightly connected external pipe or equipment.Vacuum chamber 3 inwalls are globoidal structure, contribute to the flowing and mixing in vacuum chamber 3 such as steam or air, also contribute to air-flow, medium etc. to flow out smoothly vacuum chamber 3.
The utility model in use, fluid media (medium) enters at a high speed the inner chamber of threaded nozzle 2 from threaded nozzle 2, and spray with higher flow velocity from the very little spout 9 of internal diameter, flow velocity while entering vacuum chamber 3 due to fluid media (medium) is very high, under the effect of fluid media (medium), air in vacuum chamber 3 can be taken out of and enter Venturi tube 5 by fluid media (medium), in vacuum chamber 3, be now negative pressure, the swabbing action that steam in tangential arm 6 can be produced by the negative pressure of vacuum chamber 3 enters vacuum chamber 3, and can be aspirated and produce with it certain immixture by fluid media (medium), between mixed process fluid media (medium) and steam, can produce friction, heat exchange or even chemical reaction, the fluid media (medium) mixing, steam and air flow at a high speed the compression section 10 of Venturi tube 5, along with its internal diameter diminishes gradually, it is large that the flow velocity of mixture becomes gradually, while arriving larynx section 11, it is maximum that its flow velocity reaches, then mixture enters diffuser 12, diffuser 12 internal diameters become large gradually, the flow velocity of mixture diminishes gradually, final mixture leaves Venturi tube 5 and enters in other equipment, the acceleration of 5 pairs of mixture flows of Venturi tube and slow down and usedly guaranteed that mixture can not produce adverse current, and also contribute to the generation of the processes such as mixing between mixture.
Above foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, related personnel can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on description, must determine technical scope according to claim scope.
