Description
Przedmiotem wynalazku jest sposób wytwarza¬ nia membrany do pomiarów objetosci gazu lub cieczy.The invention relates to a manufacturing process diaphragm for gas volume measurement or liquid.
Membrany stosowane do gazomierzy musza spel¬ niac specjalne wymagania w zakresie jednolitej grubosci, wysokiej elastycznosci i odpornosci na wielokrotne zginanie. Powinny posiadac duza sta¬ bilnosc ksztaltu w zakresie pojawiajacych sie. w gazomierzach naprezen (0,5 atm.), nawet po dlu¬ gim okresie uzytkowania. Membrany musza byc odporne na dzialanie czynników chemicznych oraz procesy starzenia w zakresie temperatur 5—40°C.The diaphragms used for gas meters must be met Nothing special requirements for the uniform thickness, high flexibility and resistance to multiple bending. They should have a long standing solidity of shape in terms of appearing. in pressure meters (0.5 atm.), even after prolonged periods period of use. The membranes must be resistant to chemical agents and aging processes in the temperature range of 5–40 ° C.
Dotychczas do pomiaru ilosci przeplywajacego gazu stosuje sie gazomierze miechowe, w których role membran spelnia specjalnie preparowana skóra kozia lub cieleca.So far to measure the quantity flowing gas meters are used bellows gas meters in which The role of membranes is fulfilled by a specially prepared goat or calf skin.
Znane sa sposoby zastepowania membran skó¬ rzanych, membranami wytworzonymi z tkanin po¬ wlekanych roztworami kauczuków naturalnych i syntetycznych, mieszanka perbunanu z polichlor¬ kiem winylu lub innymi tworzywami syntetyczny¬ mi o wysokich wlasciwosciach elastycznych. Sto¬ sowanie do wytwarzania membran tkanin powle¬ kanych mieszanka kauczukowa lub innymi two¬ rzywami wymaga nadawania tkaninie ksztaltu membrany w prasach wulkanizacyjnych. Proces ten jest czasochlonny i wymaga kosztownego oprzyrzadowania pras.Methods of replacing leather membranes are known with membranes made of polyurethane fabrics dragged with natural rubber solutions and synthetic, a mixture of perbunan with polychlorinated vinyl or other synthetic materials mi with high elastic properties. A hundred for the production of coated fabric membranes rubber or other materials Curves require shaping the fabric membranes in vulcanization presses. Process this one is time consuming and requires an expensive one tooling presses.
Foremniki metalowe stosowane do ksztaltowania membran z tkanin podgumowanych wymagaja bardzo precyzyjnej obróbki, gdyz najmniejsza nie¬ dokladnosc wymiarów powoduje splyniecie po¬ wloki tworzywa z tkaniny pod cisnieniem stoso¬ wanym w procesie prasowania. Ponadto koniecz¬ nosc stosowania wulkanizacji mieszanek kauczu¬ kowych w procesie formowania obniza wydajnosc.Metal moldings used for shaping membranes made of gummed fabrics require very precise machining, because the least the accuracy of the dimensions causes the trickle to drain fabric draglines made of fabric under pressure important in the pressing process. Moreover, it is imperative to Use of vulcanization of rubber mixtures components in the molding process reduce performance.
Wulkanizacja membrany trwa kilkanascie do kil¬ kudziesieciu minut w zaleznosci od grubosci po¬ wloki kauczukowej.Vulcanization of the membrane takes several to several kilograms fifty minutes depending on the thickness of the half rubber dragons.
Sposoby wytwarzania membran do pomiarów ilosci przeplywajacego gazu znano sa z nastepuja¬ cych opisów patentowych: polskiego — nr 41810, RFN — nr 865.536, nr 1.265.442, W. Brytanii — nr 1.233.178, Stanów Zjednoczonych Ameryki — nr 2.976.726, nr 3.180.145, Francji — nr 1.578.510.Methods of producing membranes for measurements the amounts of gas flowing through are known as follows patent descriptions: Polish - No. 41810, West Germany - No. 865.536, No. 1.265.442, Great Britain - No. 1.233.178, United States of America - no 2,976,726, No. 3,180,145, France - No. 1,578,510.
Sposób wytwarzania membrany do pomiarów objetosci gazu lub cieczy wedlug wynalazku pole¬ ga na tym, ze miekka folie z termoplastycznego poliuretanu poddaje sie procesowi formowania prózniowego w temperaturze 80—160°C w czasie od 10 do 90 sekund, tak aby uformowana mem¬ brana stanowila jednolita ksztaltke o jednorodnej grubosci.Method of producing a measurement membrane the volume of gas or liquid according to the invention is It is made of soft thermoplastic films polyurethane is subject to the molding process vacuum at 80-160 ° C over time from 10 to 90 seconds, so that the formed meme taken was a uniform shape with a homogeneous thickness.
Membrana uzyskana sposobem wedlug wynalaz¬ ku posiada jednakowa wytrzymalosc i odpornosc na starzenie na calej swojej powierzchni, jest ga¬ zoszczelna i odporna na dzialanie czynników che¬ micznych.The membrane obtained by the method of the invention ku has the same strength and resistance to aging over its entire surface, it is ga watertight and resistant to chemicals mical.
Przyklad. Folie z termoplastycznego poliure¬ tanu (Desmopan 385) o grubosci 0,14 mm tnie sie 99 5963 99 596 4 na kwadraty o wymiarach 280X280 mm, nastepnie poddaje sie : procesowi formowania prózniowego w nizej podanych warunkach: — temperatura wstepnego nagrzewania — 120 DC —: czas wstepnego nagrzewania folii promienni¬ kami podczerwieni — 15 sekund — czas formowania prózniowego — 15 sekund.Example. Thermoplastic polyurethane films Tanu (Desmopan 385) 0.14 mm thick is cut 99 5963 99 596 4 into squares measuring 280X280 mm, then undergoes: the process of vacuum forming under the following conditions: - pre-heating temperature - 120 DC -: time to pre-heat the radiant film infrared light - 15 seconds - vacuum forming time - 15 seconds.
Uformowana ksztaltke wyjmuje sie z foremnika. obcina nadmiar folii. Otrzymana membrana jest gotowa do montazu w komorze gazomierza.The formed shape is removed from the mold. cuts off excess foil. The resulting membrane is ready for installation in the gas meter chamber.
