Amavalvu anemigqa ayizici ezibalulekile kunoma iyiphi inqubo yezimboni ehilela ukuphathwa kwemidiya ebolayo noma elimazayo.Yenzelwe ukumelana nemiphumela eyingozi yezinto ezinjalo futhi iqinisekise ukusebenza kahle.Kulesi sihloko, sizohlola ukubaluleka kwama-valve anemigqa, ukusetshenziswa kwawo, kanye nezinzuzo abahlinzeka ngazo.
Ivalvu elayishiwe empeleni iyivalvu enomugqa wangaphakathi owenziwe ngezinto ezifana ne-PTFE (polytetrafluoroethylene) noma i-PFA (perfluoroalkoxy).Lawa ma-liner awasebenzi ngamakhemikhali futhi anikeza ukumelana okuhle kakhulu nohlu olubanzi lwamakhemikhali alimazayo, ahlanganisa ama-asidi, ama-alkali, izinyibilikisi, kanye nesitimu esishisa kakhulu.
Enye yezinto ezisetshenziswa kakhulu ama-valve anemigqa isembonini yamakhemikhali.Izitshalo zamakhemikhali ziphatha izinto ezisebenza kakhulu ezingagqwalisa izinto zamavalvu ezivamile, zibangele ukuvuza, ukungasebenzi, ngisho nezimo eziyingozi.Amavalve anemigqa anemigqa evikela ukubola eqinisekisa ubuqotho benqubo futhi ivimbele noma yikuphi ukusabela okungafuneki phakathi kwemidiya kanye nevalvu.
Ngokunjalo, ama-valve anemigqa asetshenziswa kakhulu embonini yezemithi, lapho ukuhlanzeka okuphezulu nokuba msulwa kwenqubo kubalulekile.Ulwelwesi olusetshenziswa kula mavalvu alukwazi nje ukumelana namakhemikhali abolayo kodwa lubuye lubushelelezi okwenza kube lula ukulihlanza nokubulala amagciwane.Lokhu kuvimbela noma yikuphi ukungcoliswa noma ukusulelana ngokwehlukana, kuqinisekisa ukuphepha kanye nekhwalithi yemithi.
Imboni yezimayini iphinde ithembele kakhulu kumavalvu alayini ngenxa yesimo esibi sezinto ezihilelekile.Imisebenzi yezimayini ivamise ukuphatha i-slurry, okuyingxube yezinhlayiya eziqinile ezilengiswe oketshezini, okungabangela ukuguga okukhulu kuma-valve.Amavalvu afakwe olayini anamalayini angagugi aklanyelwe ngokukhethekile ukumelana nemiphumela enolaka yaleyo mithombo yezindaba, ukwelula impilo yesevisi yevalvu futhi kuncishiswe isikhathi sokuphumula sokulungiswa noma ukushintshwa.
Ezinye izimboni ezihlomula ngamavalvu afakwe ulayini zihlanganisa uwoyela negesi, amakhemikhali kaphethiloli, i-pulp nephepha, ukuhlanza amanzi angcolile kanye nokuphehla ugesi.Lezi zimboni zidinga ukuphatha imidiya ebolayo, izingcindezi eziphakeme kanye nezinga lokushisa elidlulele, konke okungalawulwa ngokuphumelelayo ngokusebenzisa ama-valve anemigqa.
Ukwengeza, ama-valve anemigqa anikeza izinzuzo eziningana ngaphezu kwama-valve angalayishiwe.Ngaphezu kokumelana kwazo namakhemikhali okuhle kakhulu, zine-coefficient ephansi yokungqubuzana, okuholela ekwehleni kokucindezela okuncane ku-valve.Lokhu konga amandla futhi kukhulisa ukusebenza kahle kohlelo lonke.Ama-valve anemigqa ayaziwa futhi ngamakhono awo aphezulu okuvala, ukunciphisa ukuvuza nokuqinisekisa ukuvala okuqinile.
Kafushane, ama-valve anemigqa adlala indima ebalulekile ezimbonini eziphatha imidiya ebolayo noma elimazayo.Izintambo zabo ezingasebenzi ngamakhemikhali zinikeza ukumelana okuhle kakhulu namakhemikhali abolayo, okuwenza abaluleke kakhulu lapho kusebenza khona ubuqotho benqubo.Kusukela ezimbonini zamakhemikhali kuya embonini yemithi, kusukela ekusebenzeni kwezimayini kuya ekuphehleni ugesi, ama-valve anemigqa ahlinzeka ngezixazululo ezinokwethenjelwa, ezihlala njalo.Banikeza izinzuzo eziningi, okuhlanganisa ukumelana nokugqwala, ukusebenza kahle kwamandla namandla okubeka uphawu aphakeme, okubenza balungele izinqubo ezihlukahlukene zezimboni.Ngakho ngokuzayo lapho uhlangana nevalvu elayishiwe, khumbula indima yayo ebalulekile ekuqinisekiseni ukusebenza kahle nokuphephile kwezimboni ezingenakubalwa.
