I-Valve yeBhola yeJacket ye-Insulation: Izisombululo zoLawulo lwe-Fluid oluSebenza kakuhle
I-Valve yeBhola yeJacket ye-Insulation: Izisombululo zoLawulo lwe-Fluid oluSebenza kakuhle
Ivalve yebhola egqunywe ngebhatyi luhlobo lwevalve ene-insulation elungileyo kunye neempawu zokupholisa. Ububanzi bayo buhambelana nobubanzi bombhobho, obunokunciphisa ngokufanelekileyo ukulahleka kobushushu bombhobho. Olu hlobo lwevalve lusetyenziswa ikakhulu kwiinkqubo ezahlukeneyo ezifana nepetroleum, iikhemikhali, i-metallurgical, imveliso, kunye nokutya, kwaye isetyenziselwa ukuthutha imidiya ephezulu ye-viscosity eya kuqinisa kwiqondo lokushisa.
Iimpawu zeevalvu zebhola ezifakwe ibhatyi ziquka ikakhulu la manqaku alandelayo:
1. Ukuxhatshazwa kwamanzi kuncinci, kwaye i-coefficient yayo yokumelana ilingana neyomibhobho yobude obufanayo;
2. Isakhiwo esilula, ubungakanani obuncinci, kunye nobunzima obulula;
3. Iqinile kwaye inokuthenjwa, kunye nokusebenza kakuhle kokutywinwa, iplastiki isetyenziswa ngokubanzi njengento yokutywina kwaye isetyenziswe ngokubanzi kwiinkqubo zokucoca;
4. Kulula ukusebenza, ngokukhawuleza ukuvula nokuvala, kunye nokujikeleza kwe-90 ° kuphela ukusuka ekuvuleni ngokupheleleyo ukuya kukuvalwa ngokupheleleyo, ukuququzelela ulawulo olukude;
5. Ukugcinwa ngokufanelekileyo, ulwakhiwo olulula lwevalvu yebhola, kunye namakhonkco okutywina ashukumayo, okwenza ukuchithwa kunye nokutshintshwa kube lula ngakumbi;
6. Xa ivuliwe ngokupheleleyo okanye ivalwe ngokupheleleyo, iindawo zokutywina zebhola kunye nesihlalo sevalvu zibekwe zodwa kumbindi. Xa isiphakathi sidlula, asisayi kubangela ukhukuliseko lomphezulu wokutywina wevalve;
7. Inoluhlu olubanzi lwezicelo, ezinobubanzi ukusuka kwiimilimitha ezimbalwa ukuya kwiimitha ezininzi, kwaye zingasetyenziswa ukusuka kwi-vacuum ephezulu ukuya kuxinzelelo oluphezulu.
Ukucaciswa koyilo, ubude besakhiwo, uvavanyo loxinzelelo loxinzelelo lweflange kunye nokuhlolwa kweevalvu zebhola ezifakwe ibhatyi zilandela imigangatho efana ne-GB/T9113, JB/T79, JB/T9092, GB/T12221, GB/T12224, GB/T12237, GB/T13927 , AP1598, HG/T20592, EN1092, njl.
Izinto eziphambili zecandelo lebhatyi efakwe kwiivalvu zebhola zibandakanya ibhatyi (PTFE), isihlalo sevalve (WCB), umzimba wevalve (WCB), umsesane wokutywina (PTFE, ulungelelwaniso lwepolystyrene), ibhola (insimbi engenasici), isiqu sevalve (1Cr13), ukupakisha ( igraphite eguqukayo), kunye nokupakisha idlala (WCB).
Ngokubanzi, iivalve zebhola ezifakwe ibhatyi luhlobo lwevalve enokusebenza okuphezulu, ukusebenza lula, kunye nokugcinwa lula. Zisetyenziswa ngokubanzi kwiinkqubo ezahlukeneyo kwaye zilukhetho olufanelekileyo lokuhambisa imidiya ephezulu ye-viscosity.
