Vynález sa týká membránového kapacitného rýchlomera toku kvapalín.BACKGROUND OF THE INVENTION The present invention relates to a membrane fluid flow rate meter.
Soteraz používané metody merenia rýchlosti toku kvapalín eá založené najma na prin-cipech vrtulkových rýchlomerov, napr. Voltmanovho křidélka. Nevýhodou vrtulkových rýchlo-merov je, že sa rotačně uložená vrtulka v třecích ložiskách často zadiera najma priznečistění ložiska a okrem toho je výroba vrtulky poměrně složitá a drahá.The methods used so far to measure the flow velocity of ea based primarily on propeller velocity principles, such as the Voltman wing. The disadvantage of the propeller speed blades is that the rotationally mounted propeller in the friction bearings often selects the bearing cleaning and, moreover, the propeller production is relatively complex and expensive.
Uvedené nedostatky odstraňuje membránový kapacitný rýchlomer toku kvapalín, v ktoromje v membránovom telese upevněná polymérová membrána stlačená predpatou pružinou, opretáo pružinové sedlo podl’a vynálezu, ktorého podstata spočívá v tom, že na profilovanejpolymérovej membráně je nalepená pohyblivá doska kondensátora a pevná doska kondensátoraupevněná v izolačnom krúžku s vývodmi a na rárke zalisovanej v membránovom telese jenasunutá hadica s tesniacim závitovým krúžkom a ňalgim tesniacim krážkom.The above mentioned drawbacks are eliminated by a membrane capacitive fluid flowmeter in which a polymer membrane mounted in a membrane body is compressed by a prestressed spring, supported by a spring seat according to the invention, wherein a movable plate of a condenser is fixed on the profiled polymer membrane and a solid plate of condenser fixed in the insulation a ring with outlets and a push-fit hose with a sealing threaded ring and a sealing gasket in the diaphragm body.
Vynález membránového kapacltného rýchlomera toku kvapalín umožňuje rýchlo meratokamžitá rýchlosť toku vody a ostatných kvapalín a diaTkový přenos ádajov, přitom namě-řené hodnoty možno indikovat na čislicovej stupnici.The invention of a diaphragm capacitive liquid flow rate meter allows a rapid instantaneous flow rate of water and other liquids, and a diaphragm transfer of the request, while the measured values can be indicated on a numerical scale.
Membránový kapacitný rýchlomer toku kvapalín je v řeze znázorněný na pripojenom .výkrese. V telese J. je upevněná profilovaná polymérová membrána £, ktorá má na právej straněnalepená pohyblivá došku 2 kondensátora. Silové áčinky tečácej kvapaliny zachytává pred-patá pružina 1 opretá o nastavitelné pružinové sedlo í so závitom. Profilovaná polymérovámembrána 2 je upevněná v sedle telesa i v izolačnom krážku £, v ktorom je umiestnená ajpevná doska 1 kondensátora s vývodom 2·A diaphragm capacitor fluid flowmeter is shown in cross-section in the attached drawing. A profiled polymer membrane 6 is mounted in the body J. and has a movable end 2 of the condenser attached thereto. The preload spring 1, supported by an adjustable spring seat with thread, catches the flowing fluid force bars. The profiled polymer membrane 2 is fixed in the seat of the body and in the insulating groove 6, in which the fixed plate 1 of the condenser with the outlet 2 is also located.
Na rúrke 12 zalisovanej v telese 1 je nasunutá hadica 13 s tesniacim závitovým kráž-kom 14 a tesniacim krážkom 15. Pružinové sedlo i so závitom sa zaistí po kalibráciirýchlomera skrutkou 16. Pri meraní rýchlosti toku kvapalín je l’avá strana profilovanejpolymerovej membrány 2, v priamom styku s prádiacim médiom a směr prádnic je rovnoběžnýs osou symetrie polymérovej membrány 2. V důsledku odklonu prádnic na profilovanej polymérovej membráně 2 sa vytvoří sila P,Ktorá pdsobí na polymérová membránu 2 podl’a vztahu P = Gs/g.c.sin alfa, kde Gg jesekundové množstvo prietoku kvapaliny, ktoré je profilovanou polymérovou membránou 2vychýlené z ρβvodného směru toku, g je gravitačné zrýehlenie, c je rýchlosť toku kvapa-liny a alfa je uhol odklonu prádnic od pdvodného směru.On the tube 12 pressed in the body 1, a hose 13 is inserted with a sealing threaded groove 14 and a sealing groove 15. The spring seat with the thread is secured after calibration of the speedometer with the screw 16. When measuring the flow rate of the liquids, the left side of the profiled polymer membrane 2, in direct contact with the laundry medium and the direction of the linen is parallel to the axis of symmetry of the polymer membrane 2. As a result of the linen being deflected on the profiled polymer membrane 2, a force P is formed which acts on the polymer membrane 2 according to the relation P = Gs / gcsin alpha, where Gg a second flow rate of liquid which is a profiled polymer membrane 2 deflected from the downstream flow, g is a gravitational crushing, c is a flow rate of liquid, and alpha is an angle of deflection of laundry from the downstream direction.
Pre meraná rýchlosť toku kvapaliny potom platí c = P.g/Gs.sin alfa. Přitom třebarýchlomer kalibrovat v ciachováných hydro-kanáloch. Sila P je v rovnováhe s tuhostousystému polymérovej membrány 2 PM a pružiny i Pz, pretože platí, že P = P^j + Ρ%. V ddsled·ku pdsobenia dynamického tlaku vznikne v mieste 17 elastická deformácia profilovanejpolymérovej membrány 2 jf, ktorá sa prejaví v zmene kapacity Ac, vytvorenej dvojieoudosák i a 2 kondensátora.For the measured liquid flow rate then c = P.g / Gs.sin alpha applies. To do this, calibrate the gauge in calibrated hydro-channels. The force P is in equilibrium with the rigid system of the polymer membrane 2 PM and the spring i Pz, since P = P ^ j + P%. As a consequence of the application of the dynamic pressure, the elastic deformation of the profiled polymer membrane 2 is formed at the location 17, which results in a change in the capacitance Ac formed by the double-baffle i and 2 of the condenser.
Tieto změny kapacity Δc sá úměrné změnám deformácie profilovanej polymérovej mem-brány 2, t. j. c je ámerné Ay. Změny barometrického tlaku počas merenia neovplyvňujúmerané výsledky, pretože na pravá aj l’avá stranu profilovanej polymérovej membrány 2pdsobí stále rovnaký barometrický tlak pomocou hadice 13. ktorá je spojená s atmosférou.Rozsah rýchlomera sa nastavuje predpatím pružiny 4.These changes in capacity Δc are proportional to the deformations of the profiled polymeric membrane 2, i.e. c is the black Ay. Barometric pressure changes during the measurement do not affect the results because the same barometric pressure is still applied to the right and left side of the profiled polymer membrane by the hose 13 which is connected to the atmosphere. The speedometer range is adjusted by the spring bias 4.
Membránový kapacitný rýchlomer toku kvapalín možno využit na meranie rýchlosti tokukvapalných médií tak v otvorených ako aj uzavretých kanáloch a potrubiach.The diaphragm capacity flowmeter can be used to measure the flow rate of liquid media in both open and closed channels and pipes.
