Yintoni i-Triple eccentric butterfly valve flange?
Ivalvu yebhabhathane engaqhelekanga kathathuiflengi(ekwaziwa ngokuba yi-triple offset butterfly valve) iye yaveliswa kweli tyala.
Kukho iimpawu ezininzi zeiivalvu zebhabhathane ezingaqhelekanga ezintathuiflengi.Kukho isihlalo sevalvu esihambelana nomzimba, esinee-engile zokuhlala ezilungiselelwe kakuhle, ezigqunywe ngezinto ezingagugiyo ezifanelekileyo ukuvula nokuvala izigidi, intsimbi engatyiwayo yokumelana nokugqwala, kunye nezixhobo zobushushu obuphezulu. Kwaye indandatho yokutywina ethambileyo enezingqi ezininzi okanye indandatho yokutywina eqinileyo inamathele kwidiski yebhabhathane. Olu hlobo loyilo luvumela ukuba ivalvu yebhabhathane engaqhelekanga kathathu imelane ngakumbi nokutshayiswa kobushushu okanye iincopho zoxinzelelo kunye nokugqwala, xa kuthelekiswa neevalvu zebhabhathane zemveli.
I-flange ye-valve yebhabhathane engaqhelekanga kathathukwaziwa njengeivalvu yebhabhathane ephindwe kathathu, luhlobo olunye lweevalvu zebhabhathane ezisebenza kakuhle, ezenzelwe iimeko zokusebenza zoxinzelelo oluphezulu, ubushushu obuphezulu, kunye neefrikhwensi eziphezulu zokuvula nokuvala.
akukho kuvuza kwe-zero yethuivalvu yebhabhathane engaqhelekanga kathathuiflengiIsetyenziswa yiringi yokutywina yentsimbi engagqwali edityanisiweyo efakwe kwidiski. Uyilo lokujikeleza okujike ngasekunene ngaphandle kokungqubana lusetyenziswa ngumgaqo ongaqhelekanga we-triple eccentric. Isusa ukungqubana phakathi kwesihlalo kunye neringi yokutywina ngokujikeleza kwe-90º, i-torque encinci ithetha ukuba singayiqala ivalvu nge-actuator encinci, ukuze songe iindleko ezininzi kunye nendawo.
Xa ivalvu ivaliwe, i-torque yendlela yokudlulisa inokunyuka ukuze inike imbuyekezo. Oku kuphucula kakhulu ukusebenza kokutywina kweivalvu yebhabhathane engaqhelekanga kathathukwaye yandisa ubomi benkonzo yayo.
i-flange ye-valve yebhabhathane engaqhelekanga kathathuuyilo
- I-offset yokuqala kukuba i-valve shaft ingasemva kwe-disc shaft ukuze i-seal ikwazi ukuvala ngokupheleleyo isihlalo se-valve.
- I-offset yesibini kukuba umgca ophakathi we-valve shaft uthintelwe kumbhobho kunye nomgca ophakathi we-valve ukuze kuthintelwe ukuphazamiseka kokuvulwa nokuvalwa kwe-valve.
- Ingxaki yesithathu kukuba i-axis yekhoni yesihlalo iyaphambuka kumgca ophakathi we-valve shaft, nto leyo ephelisa ukungqubana ngexesha lokuvala nokuvula kwaye ifezekisa uphawu lokucinezelwa olufanayo olujikeleze isihlalo sonke.
Oku kungasentla kukwazisai-flange ye-valve yebhabhathane engaqhelekanga kathathuLuhlobo lwevalvu yebhabhathane esebenza kakhulu esetyenziswa ngoku kwiindawo ezininzi.
Iimpawu eziphambili ze-flange ye-flange ye-butterfly eccentric kathathu
- Izitulo zeStellite® zebanga lesi-6 zibonelela ngokuqina okugqwesileyo.
- Iireferensi zediski ezivulekileyo/ezivaliweyo kunye nesalathisi sendawo yediski yangaphandle zenza kube lula ukufakela/ukususa iinkqubo kwi-API 609.
- Indandatho yesitywina yesinyithi esidityanisiweyo iqinisekisa ukusasazwa okugqibeleleyo kwamandla okuhlala kujikelezo lwesihlalo olucwangciswe ngokuchanekileyo.
- Indawo ejongene neFlange iqinisekisa ukuba i-bolting nut kunye ne-washer planarity zihambelana, nto leyo enyusa ukuthembeka kunye nokhuseleko lwamalungu.
- Iigaskets zenxeba ezijikelezayo, izitywino kunye neeringi zokupakisha zinokutshintshwa ngaphandle kwezixhobo ezikhethekileyo.
- Iibheringi ezinzima ziyamelana nemithwalo yoxinzelelo oluphezulu kunye nokuguguleka.
- Ukuphathwa komngcipheko wokukhupha umngxuma ngaphakathi nangaphandle kuhambelana nemigangatho yamazwe ngamazwe.
