Embodiment
The invention will be further described below in conjunction with specific embodiment, but protection domain of the present utility model is not limited thereto.
As Fig. 1,2, shown in 3, this soap film flowmeter comprises main frame body 1, and by soap lye chamber base 2, admission piece 3, soap-film pipe 4, front apron 5, rupture of membranes chamber loam cake 6, miniature data line connector 7, back seat 8, skinning button 9, spring 10, bearing 11, base pressing plate 12, upper mounted plate 13, light barrier 14, RS232 interface 15, emission light barrier 16, bottom plate 17, last base 18, outlet nozzle 19, bottom nozzle 20, play zona 21, base tray 22, square rupture of membranes groove 23, the soap-film tube module that dentation profile 24 is formed, its with main frame body 1 between activity be connected;
Soap-film pipe 4 by last bottom nozzle 18,20 and rupture of membranes chamber and soap lye chamber link together; It is indoor that base pressing plate 12 is contained in rupture of membranes, and the location needs accurately when playing fixation, to guarantee can flow back to soap-film pipe 4 after soap lye breaks; Rupture of membranes chamber loam cake 6 is tightly connected by O type circle and last base 18; Bottom nozzle 20 is fixed on soap lye chamber base 2 by O type circle, guarantees sealing; Play zona 21 and skinning button 9 usefulness bearings 11 and link together, and be with spring 10 at skinning button 9, guaranteed that zona 21 can automatically reset; Light barrier 14 and emission light barrier 16 are separately fixed in bottom plate 13,17 the corresponding groove; front apron 5 and back seat 8 are connected by sunk screw; 5 pairs of soap-film pipes 4 of front apron shield; mounting circuit boards in back seat 8 mounting grooves; circuit board links to each other with the RS232 interface; thereby connect miniature data line connector 7, but the separate connection computer is finished the record memory function thereby also can connect main frame body 1.The soap-film tube module is connected with main frame body 1 by base tray 22.Wherein, playing zona 21 is a kind of new structure, is made up of the dentation profile 24 with certain radian and rupture of membranes groove 23, can stablize and realize continuous single skinning; Dentation profile 24 is arcuation, and square rupture of membranes groove 23 is positioned in the middle of the arcuation tooth.
The base tray 22 of soap-film tube module by the bottom is fixed on the main frame 1 in the mode that magnet adsorbs, to an amount of soap lye of the indoor adding of soap lye, aspiration pump is connected to outlet nozzle 19 by pipeline, press skinning button 9 after the start to the bottom, can in the middle of playing zona 21, form a soap-film after unclamping button, soap-film can rise in soap-film pipe 4 under the air-flow effect, can trigger luminotron emission light barrier and light barrier in the uphill process, processor can calculate the present flow rate value according to initiating terminal and receiving end signal; Break after soap-film arrives soap-film pipe 4 top base pressing plates 12, this part soap lye can be back to the soap lye chamber along soap-film pipe 4 inwalls.Can realize recording memory function also can realizing the separate records memory function when soap-film tube module monomer is directly linked to each other with computer by data line when with data line soap-film tube module and main frame 1 being linked together.
Because surface tension F is directly proportional with marginal length L, under the certain situation of soap lye concentration, the separatrix is more short, and surface tension is more little, in the present embodiment, because the surface of contact of soap lye and air is slit, the separatrix is very short, so surface tension is less relatively, bubble is easier to break, thereby the soap lye that guarantees unnecessary soap lye and backflow can not form bubble at short notice again, has avoided the appearance of two films; Simultaneously, 24 pairs of pulling force of dentation profile have certain buffer action, effectively avoid owing to pulling force cause too greatly can not the skinning situation generation, namely realize stable single skinning; Owing in soap-film tube module and the main frame the relatively independent Circuits System with memory function is arranged, be divided into independently that monomer uses so the soap-film tube module is removable; Because its two circuit has versatility, so can lump together use again.
