I-Soft Sealing Flange Double Eccentric Butterfly Valve (Uhlobo lweShaft eyomileyo)

Inkcazo yeMveliso

Iimpawu eziphambili zeSakhiwo

1. Uyilo oluphindwe kabini oluyi-Eccentric
   • Ubukhulu Bokuqala: IivalvuUmngxuma ususwa embindini wediski, nto leyo enciphisa ukungqubana ngexesha lokuvula/ukuvala kwaye inciphisa ukuguguleka kwiindawo zokuvala.
   • Ukulingana kwesibini: I-shaft ichasene ngakumbi nomgca ophakathi wepayipi, nto leyo eyenza "isiphumo sokuhlanganisa" esiphucula ukusebenza kokutywina njengoko idiski ivala.
   • Inzuzo: Inika ukuthembeka okuphezulu kokutywina kwaye yandisa ubomi benkonzo xa kuthelekiswa noyilo olune-eccentric enye okanye olune-concentric.
2. Indlela Yokutywina Ethambileyo
   • Ivalvu isebenzisa iringi yokutywina ethambileyo (eyenziwe nge-EPDM, i-NBR, okanye i-PTFE) efakwe emzimbeni wevalvu okanye kwidiski, ukuqinisekisa ukuvalwa komoya kunye nokuhambelana nemidiya eyahlukeneyo (umz., amanzi, iioyile, iigesi, kunye nolwelo olungarhawuzeliyo).
   • Inzuzo: Amanqanaba aphantsi okuvuza (ahlangabezana nemigangatho ye-API 598 okanye ye-ISO 15848) kunye ne-torque encinci efunekayo ukuze isebenze.
3. Ukwakhiwa kweShaft eyomileyo
   • Umngxuma uvalwe ngokwahlukileyo kumjelo wemidiya, nto leyo ethintela ukudibana ngqo nolwelo. Olu yilo lususa iindlela zokuvuza ezinokwenzeka kwi-shaft kwaye lunciphisa iingozi zokugqwala, ingakumbi kwiindawo ezinobundlongondlongo.
   • Icandelo Eliphambili: Izitywino zesiqu ezikumgangatho ophezulu (umz., ukupakisha okuluhlobo lwe-V okanye izitywino zoomatshini) ziqinisekisa ukuba akukho kuvuza ecaleni kweshaft.
4. Uqhagamshelo lweFlange
   • Yenzelwe ii-flange interfaces eziqhelekileyo (umz., i-ANSI, i-DIN, i-JIS) ukuze kube lula ukuyifaka kwiipayipi. Uyilo olu-flanged lubonelela ngozinzo lwesakhiwo kwaye lwenza kube lula ukugcinwa.

Umgaqo Wokusebenza

• Ukuvula: Njengoko umngxuma ujikeleza,i-eccentric ephindwe kabiniIdiski isuka kwindawo evaliweyo, isuka kancinci kancinci kwisitywina esithambileyo. Ii-offsets ezingaqhelekanga zinciphisa uxinzelelo lokuqala loqhagamshelwano, zivumela ukusebenza okubushelelezi nokungashukumiyo.
• Ukuvala: Idiski ijikeleza umva, kwaye i-geometry ephindwe kabini idala isenzo sokutywina esiqhubekekayo. Isiphumo sokuqhawula sonyusa uxinzelelo loqhagamshelwano phakathi kwediski kunye nesitywina, okuqinisekisa ukuvalwa okuqinileyo.
• Qaphela: Uyilo lomngxuma owomileyo luqinisekisa ukuba umngxuma awuchaphazeleki bubushushu bemidiya, uxinzelelo, okanye ukubola, nto leyo ephucula ukuthembeka kwayo iyonke.

Iinkcukacha zobugcisa

• Unyango Lwamanzi: Amanzi okusela, amanzi amdaka, kunye neenkqubo zogutyulo lwelindle (zifuna ukuvalwa okuphezulu ukuze kuqinisekiswe imigangatho yococeko).
• Ishishini leeKhemikhali: Ulwelo oludlakadlaka, iiasidi, kunye neealkali (umngxuma owomileyo ukhusela ekuhlaselweni ziikhemikhali).
• Iinkqubo ze-HVAC: Imibhobho yomoya opholileyo kunye neyokufudumeza (i-torque ephantsi yokusebenza rhoqo).
• Iikhemikhali zePetrochemical kunye neOyile/iGesi: Izixhobo ezingezizo ezirhabaxa ezifana neoyile, igesi, kunye nezinyibilikisi (ukuvalwa okuthembekileyo kwiinkqubo ezibalulekileyo).
• Ukutya Neziselo: Ukusetyenziswa kococeko (izitywino ezihambelana ne-FDA ziqinisekisa ukhuseleko lwemveliso).

• Iingenelo ngaphezu kweeValve zeMveli

  • Ukutywina Okuphezulu: Izitywina ezithambileyo ziyasusa ukuvuza, zilungele ukusetyenziswa okufuna ukhuseleko lokusingqongileyo okanye ubunyulu obuphezulu.
  • Ukusebenza kakuhle kwamandla: Ukusebenza kwe-torque ephantsi kunciphisa iimfuno zamandla okusebenza, kunciphisa iindleko zokusebenza.
  • Ubude: Uyilo olunemiphetho emibini lunciphisa ukuguguleka, ngelixa umngxuma owomileyo ukhusela ekungcoleni, nto leyo eyandisa ubomi benkonzo.
  • Ukonga Isithuba: Ulwakhiwo oluncinci xa luthelekiswa neevalvu zesango okanye zeglobe, zilungele ukufakwa kweendawo ezinqongopheleyo.

  Iingcebiso Zokugcina Nokufaka

  • Ukufakelwa: Qinisekisa ukuba iiflange zilungelelanisiwe kwaye iibholithi ziqiniswe ngokulinganayo ukuze kuthintelwe uxinzelelo emzimbeni wevalvu.
  • Ulondolozo: Hlola rhoqo isitywino esithambileyo ukuba asigugi kwaye usitshintshe ukuba sonakele. Thambisa i-shaft kunye ne-actuator rhoqo ukuqinisekisa ukusebenza kakuhle.
  • Indawo yokugcina: Gcina kwindawo eyomileyo, engenathuli, ivalvu ivulekile kancinci ukuze kuncitshiswe uxinzelelo kwisitywini.
  Le valve idibanisa ubunjineli obuphambili kunye noyilo olusebenzayo, inika isisombululo esithembekileyo nesingabizi kakhulu kwiimfuno zanamhlanje zolawulo lokuhamba kwamanzi kwimizi-mveliso. Ukuze wenze ngokwezifiso ezithile (umz., ukuphuculwa kwezinto okanye ukugqunywa okukhethekileyo), nceda uqhagamshelane nomvelisi.
