Detailed description of the invention
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, and basic structure of the present invention is only described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, draw a mouthful adjustable type medium injection device, comprise body 1 and threaded nozzle 2, body 1 is provided with vacuum chamber 3, screwed hole 4, Venturi tube 5 and arm 6, wherein the coaxial connection of screwed hole 4 and Venturi tube 5 is at vacuum chamber two ends, in 3 side weeks of vacuum chamber, be tilted to screwed hole 4 axis one sides and be communicated with arm 6. Between the axis of the axis of arm 6 and Venturi tube 5, angle is obtuse angle, and the steam from arm 6 high velocity stream to vacuum chamber 3 can partly be complied with the flow direction of the fluid media (medium) spraying from threaded nozzle 2 like this, makes steam and fluid media (medium) can fully produce friction or mix.
Threaded nozzle 2 can move at screwed hole 4 inside spins along its axis, in vacuum chamber 3, be provided with to regulate and draw mouth 17, the through hole 18 that regulates Yin Kou 17 centers to be provided with is positioned on Venturi tube 5 axis, through hole 18 internal diameters first diminish gradually and become gradually larger to the axis direction of Venturi tube 5 at vacuum chamber 3, a segment distance in through hole 18 is stretched in threaded nozzle 2 one end, the adjustment that relative position relation between mouth 17 is drawn in tip 8 and adjusting can produce under the condition of same fluid medium and fluid media (medium) flow velocity, the variation of vacuum chamber 3 vacuums, and can bad student's fluid media (medium) and the variation of vapor mixing degree or friction level, through hole 18 internal diameters first diminish gradually and become gradually larger to the axis direction of Venturi tube 5 at vacuum chamber 3, make through hole 18 front ends fluid medium generation to connect the effect of drawing, and the second half section has the effect of avoiding fluid media (medium) adverse current.
Threaded nozzle 2 is provided with the flat pipe portion 7 that is positioned at screwed hole 4 inside and the tip 8 that is positioned at vacuum chamber 3, the structural design of tip 8 can ensure 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 15, screwed hole 4 inwalls are with internal thread 16, internal thread 16 and external screw thread 15 structure matching, 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 in threaded nozzle 2 axis and arm 6 axis, spout 9 be positioned on crosspoint 14 or 14 left and right sides, 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 spout 9 and the relative position in 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) enters Venturi tube 5 with certain speed from compression section 10, because the compression section 10 cross section radiuses of air stream warp dwindle gradually, the flow velocity of fluid media (medium) increases thereupon, air velocity maximum while arriving larynx section 11, from Bernoulli equation, air velocity is inversely proportional to air pressure herein, it is the air pressure minimum of larynx section 11, 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 ensured 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, arm 6 free end peace pipe portion 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 present invention 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 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, fluid media (medium), steam and the air mixing flows 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 Venturi tube 5 to mixture flow and slow down and usedly ensured that mixture can not produce adverse current, and also contribute to the generation of the processes such as the mixing between mixture.
Be enlightenment according to desirable embodiment of the present invention above, by above-mentioned description, related personnel can, not departing from the scope of this invention technological thought, carry out various change and amendment completely. The technical scope of this invention is not limited to the content on description, must determine technical scope according to claim scope.
