'Ehlathini lensimbi' lamapayipi ezimboni,ama-valvezisebenze njengezisebenzi zamanzi ezithule, ezilawula ukugeleza koketshezi. Nokho, ngokuvamile ‘bafa besebancane,’ okuyinto edabukisa ngempela. Naphezu kokuba yingxenye yeqoqo elifanayo, kungani abanye benzaama-valvethatha umhlalaphansi ngaphambi kwesikhathi kuyilapho abanye beqhubeka nokusebenza? Namuhla, asilandele uchwepheshe wokulawula uketshezi u-Waters ukuze siveze iqiniso elingemuva kwesikhathi esifushane sempiloama-valve.
Izinkinga ezintathu ezinkului-valve"impilo emfushane"
Ukufuthelana Ukuya Ekufeni: Umzabalazo Okabili Wengcindezi Ephezulu kanye Nokugqwala Komphumela Wokucindezela Okuphezulu: Lapho ingcindezi yesistimu idlula kude imikhawulo yedizayini yevalvu,i-valveumzimba nezimpawu zingaphansi kwengcindezi enkulu, okuholela ekuwohlokeni kwesakhiwo kanye nokwehluleka kwezimpawu. Imithelela yesando samanzi esheshayo ifana nokulimala kwangaphakathi, okukwazi ukwenza ngokushesha i-valve ingasebenzi. Ukushwabadela Ukugqwala: Ezimweni ezinzima ezifana nezindawo zamakhemikhali namanzi olwandle, imidiya ebolayo isebenza njengezintende zezandla ezithambisa amathambo, igugule buthule ugqinsi lwamavalvu omzimba (ngezinga lokugqwala elingaphezu kuka-0.5 mm/ngonyaka), yenza amandla ayo abe buthaka, futhi ibangele ukubhobozwa nokuvuza. Amanzi ayaqonda ukuthi izinto ezisetshenziswayo zibalulekile, futhi ama-valve alo akhethekile (afana ne-Hastelloy ne-duplex steel) afana' nezihlangu zensimbi zegolide, 'ezithuthukisa kakhulu ukucindezela kwazo kanye nokungagqwala. Ukugqokwa Ngokusebenza Kakhulu: Ukusika Okungenalusini Ngokuguguleka Kwemithombo Yezindaba: Izinhlayiya eziqinile (ezifana ne-mineral slurry nomlotha) noma uketshezi olunesivinini esikhulu (njengesitimu namanzi e-cavitation) zilokhu zikhuculula indawo yokuvala kanye negumbi le-valve, zisebenza njengemimese eqoshiwe encane engenakubalwa. Ngokuhamba kwesikhathi, lezi zenzo zenza imifantu ejulile endaweni yokuvala, okuholela ekuhlulekeni kokuvala. Izindawo zokuvala eziqinile zengxubevange yamanzi (ezifana ne-tungsten carbide ne-STL) kanye nemiklamo ethuthukisiwe yendlela yokugeleza isebenza 'njengamahembe ensimbi' ngokumelene nalokhu 'kusikeka kwenkulungwane' okungaphezi.
Ukuvinjwa kwe-asphyxiation: ukuvinjelwa okubulalayo kokungcola nesilinganiso
Ukungena kokungcola: I-weld slag, ukugqwala, nezinto zangaphandle zingangena epayipini futhi zibambeke phakathi kwesihlalo sevalvu nomongo. Lokhu kungabangela ukuthi i-valve ihluleke ukuvala noma ukuvuleka kahle, futhi ezimweni ezimbi kakhulu, kulimaze indawo eqondile yokuvala. I-crystallization emaphakathi kanye nokukala: Ezimweni ezithile (njengamanzi okupholisa noma udaka), okuphakathi kungase kucwebezele noma kukalwe ngaphakathii-valve, ukuvala ngokuphumelelayo amalunga e-valve, okuholela ekuvinjeni okuvilaphayo noma okuphelele. Amanzi 'imiklamo elwa nokuvala, njengama-valve ohlobo lwe-V yohlobo olukhulu lokugeleza kwebhola kanye nezakhiwo zokukhuhla, asebenza njengamathuluzi asebenzayo okusula la' mahlule egazi.'
"Iphutha" lomsebenzisi lisheshise impilo yevalvu
Ngokuvumelana neI-TWS Ivalve yophawu lwamanzi, Ukuphila isikhathi eside kwe-valve akuyona ingozi, kodwa ubunjiniyela besistimu kusukela kumklamo, ukukhethwa kwempahla, ukukhiqiza nokusetshenziswa:
Ukufanisa Okunembile, Okuklanyelwe Ngokuqondile: Yenza ukuhlaziya okuphelele kwezimo zokusebenza (ingcindezi, izinga lokushisa, okuphakathi, okuqukethwe yizinhlayiyana, kanye nemvamisa yokusebenza) ukuze ukhethe uhlobo olufanele lwevalvu (i-valve yesango, i-globe valve, i-valve yebhola,uvemvane valve) nezinto ezibonakalayo. Izingxenye Eziyinhloko, Ukulwela Ukuphelela: Ipheya elivalekayo lenziwe ngengxubevange eqinile engagugi futhi imelana nokugqwala; isiqu se-valve senziwe ngezinto ezimelana nokugqwala okunamandla aphezulu ngokwelashwa okuthuthukisiwe kwendawo; Izingxenye ezithwala ingcindezi ziqinisekiswa ngokuqinile ngokuhlaziywa kwe-finite element (FEA). Ubuciko, Ukulawulwa Kwekhwalithi Eqinile: Ukunemba kwemishini kuqinisekisa ukubekezelelana okunembile, futhi ukuhlolwa okuqinile okungabhubhisi (RT/UT/PT) kuqeda ukukhubazeka kwangaphakathi; yonke inqubo iwukuzibophezela ekuthembekeni. Ukukhetha Okuhlakaniphile, Ukulindela Ikusasa: Nikeza umhlahlandlela wokukhetha ochwepheshe kanye nezixazululo ezenziwe ngokwezifiso zokuqinisekisa ukuthi ama-valve 'azalwa ngesikhathi esifanele, endaweni efanele.'
Phatha yonke "inhliziyo yezimboni" kahle
Ukwehluleka ngaphambi kwesikhathi kwama-valve kuwuphawu oluyisixwayiso lwezinkinga ezingase zibe khona zesistimu futhi kumelela ukulahleka kwezinsiza nokusebenza kahle. Ngokukhetha Amanzi, ukhetha ubungcweti nokuzinikela ukuze ufake amasistimu akho oketshezi ngamandla ahlala njalo. Asinikezi kuphela imikhiqizo yama-valve ehlala isikhathi eside kodwa futhi sikhuthaza izimiso zokuphathwa kwesayensi nokusebenza okujwayelekile. Kuphela ngokuqonda, ukuhlonipha, kanye nokuphatha laba 'banakekeli basezimboni' abathule kahle lapho bengakwazi ukusebenza ngokuzinza, ngempumelelo, nangesikhathi eside ezindimeni zabo, ngokuhlanganyela baqinisekise ukuhamba kahle kwezinqubo zezimboni!
