Uhlobo lweValve yeButterfly e-Eccentric Triple
Yintoni uhlobo lwe-wafer ye-butterfly eccentric kathathu?
Uhlobo lwe-valve yebhabhathane engaqhelekanga kathathu,kwaziwa njengeivalvu yebhabhathane ephindwe kathathu, luhlobo olunye lweevalvu zebhabhathane ezisebenza kakuhle, ezenzelwe iimeko zokusebenza zoxinzelelo oluphezulu, ubushushu obuphezulu, kunye neefrikhwensi eziphezulu zokuvula nokuvala.
Ivalvu yebhabhathane enerabha eqingqiweyo, enoyilo oluvuthiweyo kunye netekhnoloji yokuvelisa, ithembekile ngomgangatho kwaye ixabisa kancinci. Kodwa kwiindlela ezinzima ezifana namaqondo obushushu aphezulu okanye xa uvula kwaye uvala rhoqo, akuvumelekanga ukusebenzisa iivalvu zebhabhathane zesihlalo esithambileyo. Ngoko ke iivalvu zebhabhathane ezitywiniweyo, isihlalo sesinyithi okanye isihlalo seceramic, ezenzelwe amaqondo obushushu aphezulu, uxinzelelo oluphezulu okanye amaza aphezulu okuvala, zaqala ukusetyenziswa, kodwa ukusebenza kokutywina kwevalvu yebhabhathane yesiqhelo etywiniweyo yayisoloko iyinto ebalulekileyo.
Uhlobo lwe-valve yebhabhathane engaqhelekanga kathathu(ekwaziwa ngokuba yi-triple offset butterfly valve) iye yaveliswa kweli tyala.
Kukho iimpawu ezininzi zeiivalvu zebhabhathane ezingaqhelekanga ezintathu.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.
Xa ivalvu ivaliwe, i-torque yendlela yokudlulisa inokunyuka ukuze inike imbuyekezo. Oku kuphucula kakhulu ukusebenza kokutywina kweivalvu yebhabhathane engaqhelekanga kathathukwaye yandisa ubomi benkonzo yayo.
akukho kuvuza kwe-zero yethuuhlobo lwe-valve yebhabhathane engaqhelekanga kathathuIsetyenziswa 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.
Uyilo lwee-offsets ezintathu
- 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 kukwazisauhlobo lwe-valve yebhabhathane engaqhelekanga kathathuLuhlobo lwevalvu yebhabhathane esebenza kakhulu esetyenziswa ngoku kwiindawo ezininzi.
Iimpawu eziphambili zevalvu zebhabhathane ezi-eccentric ezintathu zohlobo lwe-wafer
- Ulwakhiwo olusebenzisa isinyithi esipheleleyo olungatshiyo.
- 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.
- Iindandatho zesitywino se-duplex kunye ne-graphite ezinokutshintshwa ngokulula.
- Ishafti enye eqinileyo kakhulu eyenzelwe ukuhambisa/ukugcina i-torque ngokufanelekileyo.
- Izikhuseli zeebheringi zegrafiti ezilukiweyo zithintela ukungena kokungcola, ziqinisekisa ukuba i-torque isebenza rhoqo kwaye i-valve isebenza kakuhle.
- Ukupakisha i-gland kunye ne-graphite eneziqwenga ezibini kunciphisa umngcipheko wokukhupha ukungcola kwangaphandle.
- Uqhagamshelo oluqinileyo lwe-shaft-to-disc ukuze kubekho ukuqina okuphezulu kwe-shaft.
- 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.
