IValve yebhabhathane ye-Eccentric emithathu
yintoni ivalve yebhabhathane ephindwe kathathu?
Ivalve yebhabhathane eccentric kathathu,kwaziwa njengetriple offset butterfly valve, lolunye uhlobo lweevalvu zebhabhathane ezisebenza kakhulu, ezenzelwe iimeko zokusebenza zoxinzelelo oluphezulu, ubushushu obuphezulu, kunye neefrikhwensi eziphezulu zokuvula nokuvala.
Ivalve yebhabhathane enerabha ephakathi, enoyilo oluqolileyo kunye neteknoloji yokuvelisa, ithembekile kumgangatho kwaye inobuhlobo kwiindleko. Ivalve yebhabhathane eqinileyo, isihlalo sentsimbi okanye isihlalo seceramic, esenzelwe ubushushu obuphezulu, uxinzelelo oluphezulu okanye ukujikeleza okuphakamileyo kokuvala okuvulekileyo, zaqala ukusetyenziswa, kodwa ukusebenza kokutywinwa kwevalve yebhabhathane elukhuni yesiqhelo kwakuhlala kuyinkxalabo enkulu.
Ivalve yebhabhathane eccentric kathathu(ekwaziwa ngokuba yi-triple butterfly valve) iye yaqanjwa kulo mzekelo.
Kukho iimpawu ezininzi zeiivalvu zebhabhathane eziphindwe kathathu.Kukho isitulo sevalvu esidityanisiweyo somzimba, esineengile zokuhlala ezilungelelanisiweyo, ezigqunywe ngezinto ezinganxitywanga zilungele izigidi zokuvula nokuvala, intsimbi engatyiwayo yokumelana nomhlwa, kunye nezixhobo zobushushu obuphezulu. umsesane wokutywina onzima umiliselwe kwidiski yebhabhathane.Olu hlobo loyilo luvumela ukuba lwenza ivalve yebhabhathane eccentric ikwazi ukumelana nokothuka kwe-thermal okanye iincopho zoxinzelelo kunye nokubola, xa kuthelekiswa neevalvu zebhabhathane zemveli.
ukuvuza zero yethuivalve yebhabhathane eccentric kathathuiphunyezwa yi-composite steel stainless stainless sealing ring efakwe kwi-disc.Uyilo lokujikeleza okunekona ekunene kunye ne-zero friction iphunyezwa ngomgaqo-siseko owahlukileyo we-eccentric kathathu.Iphelisa ingxabano phakathi kwesihlalo kunye neringi yokutywina kumjikelezo we-90º, i-torque encinci ithetha ukuba sinokuqalisa ivalve nge-actuator encinci, ukonga iindleko kunye nendawo.
Xa i-valve ivaliwe, i-torque yendlela yokuhambisa inokunyuka ukubonelela ngembuyekezo.Oku kuphucula kakhulu ukusebenza kokutywinwa kweivalve yebhabhathane eccentric kathathukwaye yandisa ubomi benkonzo yayo.
Uyilo lwe-Triple offsets
- I-offset yokuqala kukuba i-valve shaft isemva kwe-disc shaft ukuze isitywina sivale ngokupheleleyo isihlalo sevalve.
- I-offset yesibini kukuba i-centerline ye-valve shaft ikhutshwe kumbhobho kunye ne-valve centerline ukuphepha ukuphazamiseka ekuvuleni nasekuvaleni i-valve.
- I-offset yesithathu kukuba i-axis ye-cone yesihlalo iyaphambuka kumgca ophakathi we-valve shaft, ephelisa ukungqubuzana ngexesha lokuvala kunye nokuvula kwaye ifezekise i-uniform compression seal malunga nesihlalo sonke.
Oku kungentla kukwaziswa kweivalve yebhabhathane eccentric kathathu.Luhlobo lwevalve yebhabhathane esebenza kakhulu ngoku esetyenziswa kwiindawo ezininzi.
Iimpawu eziphambili zeevalvu zebhabhathane eccentric ezintathu
- Ulwakhiwo olukwaziyo ukumelana nomlilo zonke zentsimbi.
- Izitulo zeStellite® zeBanga lesi-6 zibonelela ngokuqina okugqwesileyo.
- Iireferensi zediski ezivulekileyo/ezivaliweyo kunye nesalathisi sendawo yediski sangaphandle senza lula ukufakwa/ukususwa kweenkqubo kwi-API 609.
- Umsesane wetywina wesinyithi ohlanganisiweyo uqinisekisa ukuhanjiswa kwamandla okuhlala ngokugqibeleleyo kujikelezo lwesangqa sesitulo esichanekileyo.
- I-Flange spot ejongene nayo iqinisekisa i-bolting nut kunye ne-washer planarity, ukwandisa ukuthembeka ngokubambisana kunye nokhuseleko.
- I-duplex enamaleko amaninzi ngokulula kunye namakhonkco etywina egraphite.
- Ukomelezwe kakhulu kweshaft enye eyenzelwe ukuhambisa / ukugcina i-torque ngokufanelekileyo.
- Izikhuseli ezilukiweyo zegraphite zikhusela ukungena kokungcola, ziqinisekisa ukubaleka rhoqo kwetorque kunye nokusebenza kwevalvu.
- Iziqwenga ezibini zokupakisha idlala kunye nokupakishwa kwegraphite kunciphisa umngcipheko wokuphuma ngaphandle.
- Uqhagamshelo olukhuselekileyo lwe-shaft-to-disc ukuze kugqibelele imfezeko yeshaft.
- I-Spiral inxeba gaskets, itywina kunye namakhonkco okupakisha anokuthathelwa indawo ngaphandle kwezixhobo ezikhethekileyo.
- Iibheringi zomthwalo onzima zimelana noxinzelelo oluphezulu kunye nokunxiba.
- Ukuphathwa komngcipheko we-shaft extrusion yangaphakathi nangaphandle ihambelana nemigangatho yamazwe ngamazwe.
