Ivalve yebhola enejacket isetyenziselwa ukugcina ubushushu bolwelo ngexesha lomsebenzi ukugcina ulwelo kwindawo esezantsi ye-viscosity ukuze isebenze ivalve igudileyo kwaye kulula ngaphandle kokusebenza nzima.
Iibhatyi ziqinisekisa ukufudumeza kwevalve engaguqukiyo okanye ukuPholisa inkqubo yemidiya ukuthintela ukuqaqamba okanye ukubanjwa kwemithombo yeendaba.
Ivalve yebhatyi yebhola ineepropathi zokugquma kakuhle / ezibandayo, inokunciphisa ngokufanelekileyo ilahleko yobushushu kumajelo eendaba kumbhobho.Ivalve yebhola eneebhatyi isetyenziswa kakhulu kwiikhemikhali, kwipetroleum, kumayeza, kumashishini esinyithi kwinkqubo yombhobho.
Ngenxa yesakhiwo sevalve yesitywina kunye nesixhobo sokutywina esihambelanayo, iqondo lobushushu elisebenzayo levalve yebhola lingaphantsi kwama-200 ℃.Nangona isihlalo sinokusebenzisa izixhobo zegraphite zamandla aphezulu, ezinokuxhathisa i-300 ℃ ngexesha elifutshane, kukho iindawo ezininzi ezifunekayo zokutywinwa zisengakwazi ukutywina kwimeko yobushushu obuphezulu, ngakumbi itywina le-radial.Igraphite yamandla aphezulu ayifanelekanga kwi-radial seal.Ngokuqhelekileyo ukutywinwa kwevalve ye-radial yokutywinwa sebenzisa i-o-ring seal structure.Ke Ukusebenzisa ubushushu kuthintelwe yi-o-ring, esebenzisa i-viton, kunye nobushushu bokusebenza kwe-viton bungaphakathi kwe-200 ℃, Kwaye ayinakusetyenziswa ngaphakathi komda wobushushu ixesha elide. ixesha.Oko akunako ukwanelisa imfuno yeendlela ezininzi.Umzekelo, xa i-medium iyirosin, ifuna ubushushu bokusebenza obuyi-300 ℃, ukuze i-rosin ifumane amanzi afanelekileyo.I-O-ring njengokutywinwa ayikwazi ukuhlangabezana neemfuno.
