Ngensimbi engagqwali, ngokuvamile ibhekwa njengensimbi okungelula ukugqwala, kodwa empeleni insimbi engagqwali nayo ingagqwala.Ukumelana nokugqwala nokugqwala kwensimbi engagqwali kungenxa yokwakheka kwefilimu ye-oxide ecebile nge-chromium (ifilimu yokudlula) ebusweni bayo.Lokhu kumelana nokugqwala nokumelana nokugqwala kuhlobene.
Ukuhlola kubonisa ukuthi ukumelana nokugqwala kwensimbi emithonjeni yezindaba ebuthaka njengomoya namanzi nasemithonjeni ye-oxidizing efana ne-nitric acid kuyenyuka ngokwanda kokuqukethwe kwe-chromium kunsimbi.Uma okuqukethwe kwe-chromium kufinyelela kumaphesenti athile, ukumelana nokubola kwensimbi kushintsha kungazelelwe., okungukuthi, ukusuka kokulula ukuya kokugqwala kuya kokungelula ukugqwala, futhi ukusuka ekumelaneni nokugqwala kuya ekuqineni ukugqwala.
Ukuhlola ukuthi i-valve yensimbi engagqwali ingagqwala yini, i-valve efanayo ingafakwa ezindaweni ezihlukene ukuze kuqinisekiswe futhi kuqhathaniswe.
Ngaphansi kwezimo ezivamile, uma i-valve yensimbi engagqwali ibekwe endaweni eyomile, ngemva kwesikhathi eside, i-valve ayikho esimweni esihle kuphela, kodwa futhi ikhululekile nokugqwala.
Futhi uma i-valve ifakwa emanzini olwandle anosawoti omningi, izogqwala phakathi nezinsuku ezimbalwa.Ngakho-ke, ukumelana nokugqwala kanye nezakhiwo zensimbi engagqwali zama-valve ensimbi engagqwali nazo zidinga ukulinganiswa ngokwendawo ezungezile.
"Ngokwezici ze-valve yensimbi engagqwali ngokwayo, isizathu esenza ingabi nabala ukuthi kunongqimba lwefilimu ye-oxide ecebile nge-chromium ukuvimbela ama-athomu omoya-mpilo angaphandle nezinye izinhlayiya ukuthi zingabangeli umonakalo entweni, ukuze i-valve inezici zensimbi engagqwali."Isazi Nokho, lapho ulwelwesi lonakaliswa izici ezifana nendawo ezungezile, luzogqwala lapho kungena ama-athomu omoya-mpilo bese luhlukana nama-ion ensimbi.
Kunezizathu eziningi zokugqwala kwamavalvu ensimbi engagqwali, njengokusabela kwe-electrochemical phakathi kolwelwesi nezinye izinhlayiya zensimbi noma uthuli, kanye nokusetshenziswa komoya omswakama njengomthombo wokwakha umjikelezo webhethri elincane, okwenza insimbi engagqwali. ukugqwala okungaphezulu.
Esinye isibonelo ukuthi ifilimu yensimbi engagqwali ihlangana ngokuqondile noketshezi olugqwalayo njengama-asidi aqinile nama-alkali, okubangela ukugqwala nokunye.Ngakho-ke, ukuze i-valve yensimbi engagqwali ingagqwali, kuyadingeka ukunaka ukuhlanzwa kwezinto ezisetshenziswa nsuku zonke futhi ugcine ubuso be-valve buhlanzekile.
Ngakho, uma i-valve yensimbi engagqwali igqwalile, umsebenzisi angayixazulula kanjani le nkinga?
Okokuqala, kuyadingeka ukuhlanza nokukhuhla ubuso be-valve yensimbi engagqwali njalo ukususa okunamathiselwe futhi kuqedwe izici zangaphandle ezibangela ukugqwala.
Okwesibili, insimbi engagqwali engu-316 kufanele isetshenziswe ezindaweni ezisogwini lolwandle, ngoba impahla engu-316 ingamelana nokugqwala kwamanzi olwandle.
Okwesithathu, ukwakheka kwamakhemikhali kwamanye amapayipi ensimbi engagqwali emakethe akuhlangabezani nezindinganiso zikazwelonke ezihambisanayo futhi akuhlangabezani nezidingo ezibonakalayo ze-304, ngakho-ke kuzobangela nokugqwala.Mayelana nalokhu, ochwepheshe bathi lapho abasebenzisi bekhetha ama-valve ensimbi engagqwali, kumelwe bakhethe ngokucophelela imikhiqizo evela kubakhiqizi abahloniphekile.I-valve yensimbi engenasici, impahla enhle kakhulu, ikhwalithi enhle, ukukhetha kwakho okuthembekile ~
Kunezigameko ezimbalwa zokugqwala kwamavalvu ensimbi engagqwali.Ngokuvamile, ama-valve okuphepha enziwe ngensimbi engagqwali aphephile futhi awafani nezinye izinto.Ngakho-ke, i-valve yalesi sici ivame kakhulu endaweni yeminye imidiya eyingozi, futhi iyisihluthulelo sokuqinisekisa ukusebenza kwayo.
Ngaphezu kwalokho, ama-valve ensimbi engagqwali avame ukuxhumana nemithombo ethile ye-liquid, futhi imvelo ivame ukumanzi, futhi inzuzo ephikisana nokugqwala yalolu hlobo lwe-valve isibe inzuzo enkulu, futhi yenza lolu hlobo lwe-valve luhlale luqinile.Ukuphila kwenkonzo kunwetshwa kakhulu, futhi ithonya elingafanele lezinkinga zokugqwala ezingase zibe khona liyasuswa.
