Ama-valve okulawula ayingxenye ebaluleke kakhulu yenqubo ama-valve athile okulawula enza ukuvikelwa kwempahla ngesikhathi sokucindezela okukhulu.Ngakho ukusebenza kahle kwe-valve yokulawula kuyadingeka ekuphepheni kwemishini.Ngakho-ke uma sidinga ukuqinisekisa ukuphepha kwedivayisi kufanele i-valve yokulawula ihlolwe.Kunezinhlobo ezahlukene zama-valve okulawula njenge-globe valve, i-valve yebhola, njll. ukuqinisekisa ukuthi i-valve yokulawula isebenza kahle.Ukuhlolwa kwezingxenye zevalvu yokulawula kufanele kwenziwe futhi uma kukhona okungahambi kahle kufanele zinakekelwe.
Ukuhlola ngaphambi kokufakwa
I-valve yokulawula kufanele ihlolwe ngaphambi kokufakwa kwayo ukuze sithole ukuthi kukhona yini iphutha ku-valve yokulawula futhi ingalungiswa.Izinyathelo zokwenza ukuhlolwa kwe-valve ngaphambi kokufakwa kwayo.
• Isiqondiso sokugeleza kufanele kunqunywe ukuze kuqinisekiswe ukufakwa ngendlela efanele, amanye ama-valve awekho kabili.Ngakho-ke, lapho kufakwa ama-valve okuhlola ama-swing kufanele kubhekwe indlela yokuhamba
• Bheka i-valve ngeso lengqondo bese ubheka noma iyiphi into engaphandle kwevalvu ngoba ingalimaza ivalvu
• Indawo ye-activator kufanele inqunywe
Ekuhlolweni kwenkonzo
Ama-valve okulawula ahlolwe enkonzweni ukuze anqume ukuthi kukhona yini inkinga ku-valve ngesikhathi sokusebenza kwayo kanye nokuhlola ukuthi izingxenye zisebenza kahle yini ngaphansi kwezimo zokusebenza ezivamile.Ngesikhathi sokuhlolwa kwe-valve phakathi nenkonzo, kuzodingeka senze izinguquko ezithile ezifana nokulungisa ukupakisha ukuze i-valve igcinwe ezimweni ezinhle zokusebenza.Kudingeka sihlole ibhokisi lokugxusha nama-flange ukuze sazi ukuthi kukhona ukuvuza noma cha.Ngakho-ke uma kuneziphambeko ku-valve kufanele sithathe isinyathelo sokuzilungisa
Indlela yokuhlola i-valve yokulawula ngenkathi uyithola kumenzi?
Ukuhlola okubonakalayo
• Ukulawula ukufanisa ubuso
• Hlola isondo lesandla
• Okunamathiselwe kwesihlalo somzimba kanye nesilawuli sesihlalo kufanele kubhekwe
• Ukuqedwa kwama-flange kufanele kubhekwe
• Hlola amachweba
• Hlola ubukhulu bomzimba wevalvu
• Hlola izilinganiso zokuphela
• Isiphetho se-flange ebusweni namalunga eringi kufanele kubhekwe
• Ubuso nobuso ubukhulu
• I-diameter yangaphandle ye-flange, ububanzi bendilinga yebhawodi, ububanzi bembobo yebhawodi, ukujiya kwe-flange
• Ukujiya kwevalvu yomzimba
• Ububanzi besiqu neziphetho ezinentambo kufanele kubhekwe
Umhloli wendawo kufanele ahlole imibhalo yokuhlola kanye nanoma yimuphi umonakalo owenziwe yimishini ongenzeka ngesikhathi sokuthunyelwa.Kudingeka sihlole ukuthi i-valve ithunyelwe kahle noma cha.
Lezi zici ezilandelayo kufanele zihlolwe ukuze kuqinisekiswe ukuthi i-valve yokulawula ithunyelwa kahle yini
• Wonke amavalvu kufanele akhishwe ngokuphelele uketshezi oluhlolwayo futhi kufanele omiswe ngemva kokuhlolwa kwamanzi
• Ama-flange nama-weld flange ama-valve kufanele afakwe amakhava, futhi ububanzi bekhava kufanele bufane nobubanzi obungaphandle be-flange futhi kufanele bujiye futhi.
• Ingxenye yobuso ephakanyisiwe ye-flange kanye negroove ehlangene eyindandatho kufanele imbozwe ngamafutha anzima.Idiski evikela umswakama esindayo kufanele ifakwe phakathi kobuso obugcotshisiwe be-flange kanye nesembozo.I-diameter ye-disc kufanele ilingane nobubanzi bangaphakathi bemigodi ye-bolt
• Amaphethelo amavalvu anentambo namasokhethi weld weld kumele avikelwe ngamakepisi epulasitiki abambayo
Ukuhlolwa kwendawo
Umugqa kanye nokunye ukungapheleli okujwayelekile kwendawo kufanele kuhlolwe ukujula.Uma ukujula kungaphezu komkhawulo owamukelekayo ocaciswe ukujiya kodonga lapho-ke lokhu kungapheleli kungaba yingozi.Ngakho izingxenye kufanele zihlolwe ukuze kutholakale ukuthi azinawo yini amaphutha alimazayo.Izimpawu zemishini ekumhumeni nasemigodini kufanele zamukeleke futhi uma zeqa umkhawulo owamukelekayo kufanele zisuswe ngomshini noma ngokugaywa kunsimbi enomsindo.Ukumaka kufanele kube emzimbeni noma kumapuleti okuhlonza futhi izindlela zokumaka ezamukelekile ziphonswa, zifojiwe, zigxivizwe, zifakwe ngogesi, zifakwe i-Vibro-etched, noma i-laser-etched.Ama-valve angaqondile kufanele amakwe ngokugeleza noma inkomba yokucindezela.Ipuleti lokuhlonza kufanele limakwe ngophawu lokuhlonza lokunquma.Ama-flange ahlanganisayo amaringi kufanele amakwe ngenombolo ye-groove eyindandatho emaphethelweni e-piping flange.Kufanele kube khona inkomba yebhola, ipulaki, noma indawo yediski yamavalvu ohlobo lokujika kwekota.
