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 Fig. 1, Fig. 2, shown in Fig. 3, a kind of Venturi tube doubling device, comprise: a preferably Venturi tube 2 and six arms 10 being tightly connected with Venturi tube 2, the compression section 4 that Venturi tube 2 two ends are horn opening and expansion segment 8, centre is the trunnion section 6 that cross-sectional plane radius is less, arm 10 is tilted to compression section 4 and is communicated with 6 sealings of trunnion section, arm 10 axis and trunnion section 6 axis angles are acute angle, preferably acute angle angle is 15 °-90 °, air-flow in arm 10 can be easy to be driven towards expansion segment 8 and flow by Venturi tube 2 like this, preferably yarn wheel 12 is arranged on the corner that arm 10 is connected with trunnion section 6, and near expansion segment 8 one sides, yarn wheel 12 cliding frictions that can make yarn 16 enter the corner of trunnion section 6 from arm 10 become friction of rolling, reduce the running resistance of yarn 16 damages and yarn 16.In order to adapt to the different requirements of different product needs to yarn 16 tractive force sizes, arm 10 is with trunnion section 6 junctions near expansion segment 8 as shown in Figure 1 for the preferred a kind of embodiment of the present invention, and this kind of technical scheme Venturi tube 2 is also less to the tractive force of yarn 16 to relatively little gas in the gas pumping effect of every arm 10; Arm 10 is with trunnion section 6 junctions near compression section 4 as shown in Figure 2 for the preferred another kind of embodiment of the present invention, and this kind of technical scheme Venturi tube 2 is also larger to the tractive force of yarn 16 to relatively large gas in the gas pumping effect of every arm 10.Be communicated with external device sealing for the ease of the free end of Venturi tube 2 and the free end of arm 10, each free end is designed to the clamping ring 14 turning up, and compound rubber circle is as sealing auxiliary component.In order to reduce the impact of arm 10 air inlets on trunnion section 6 internal gas pressures, arm 10 internal diameters are less than trunnion section 6 internal diameters.Compression section 4, trunnion section 6 and expansion segment 8 are designed to coaxial configuration and are convenient to gas and yarn 16 fast smoothly by Venturi tube 2.In several embodiment of the present invention, the number of arm 10 is respectively 2 or 3 or 4 or 6, for the application force that in balance every arm 10, gas is aspirated by Venturi tube 2, the gas flow rate that reaches every arm 10 is consistent, all arms 10 are arranged into centrosymmetric structure taking the center of circle of trunnion section 6 cross-sectional planes as the center of circle, the internal diameter size of every arm 10 simultaneously, and every arm 10 axis are all identical with Venturi tube 2 axis angles.
The present invention in use, as shown in Figure 4, pressurized air enters Venturi tube 2 with certain speed from compression section 4, because the compression section 4 cross-sectional plane radiuses of air stream warp dwindle gradually, compressed-air actuated flow velocity increases thereupon, air rate maximum while arriving 6 sections of trunnions, from Bernou1li equation, air rate is inversely proportional to air pressure herein, it is the air pressure minimum of trunnion section 6, air pressure in arm 10 is greater than the air pressure in trunnion section 6, air in arm 10 is also inhaled into trunnion section 6 in arm 10, now the air-flow in every arm 10 be pooled to trunnion section 6 with the air-flow in Venturi tube 2 in together with move to expansion segment 8, the direction top rail section radius that air-flow is flowed through at expansion segment 8 becomes large gradually, gas flow rate diminish gradually slow down and, last air-flow flows out Venturi tube 2.Yarn 16 enters arm 10 separately from the free end of every arm 10, and all yarns 16 converge in trunnion section 6, enters expansion segment 8 finally leave Venturi tube 2 in company with air-flow.Yarn 16 in arm 10 rolls in the time entering the corner of trunnion section 6 on yarn wheel 12, reduces the injury gained in sports of turning to yarn 16., there is temporary transient entanglement in the interior meeting of Venturi tube 2 after multi-strand yarns 16 converges in the tractive force maximum of the air-flow that yarn 16 is subject in trunnion section 6, makes threads 16 after doubling, had each other obvolvent effect comparatively closely.
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 specification sheets, must determine technical scope according to claim scope.
