Ubume besiseko sevalve yeglowubhu
1. Ivalve yeglowubhu ibhekisa kumalungu okuvala (idiski) aqhutywa sisikhondo sevalve kunye nombindi we-axis yesitulo sevalvu yokunyusa intshukumo yevalve, kumbhobho osetyenziswa ikakhulu ukudibanisa okanye ukusika okuphakathi kumbhobho; kodwa awukwazi ukwenza i-throttling.
2. Iplastiki ye-fluorine ifakwe ngokupheleleyo i-J41F46 uhlobo oluthe ngqo, uhlobo lwe-J45F46 oluhamba ngokuthe tye, i-valve yokumisa i-J44F46 ye-cutin, ineenzuzo zesakhiwo esihlangeneyo, ukuvuleka okuguquguqukayo kunye nokuvala, ukuxhathisa okuqinileyo kwe-corrosion, i-stroke emfutshane (ngokuqhelekileyo i-diameter ye-1/4) , isetyenziswa kakhulu kwi-petroleum, iikhemikhali kunye nezinye iinkqubo zemibhobho njenge-truncation medium, Kodwa kufuneka kugxininiswe ukuba ivalve yeglobhu ene-fluorine eyenziwe ngeplastiki ithintelwe ngokungqongqo ukuba isetyenziswe njengommiselo wokuhamba, ukuze ingakhukulisi umphezulu wokutywina obangelwa ngumgangatho ophezulu- isantya esiphakathi sokuhamba emlonyeni we-throttle.
3. I-disc kunye nesiqu ziyilwe njengesakhiwo esinye ukuthintela ukubakho kwamalungu angaphakathi aphuma ngokukhawuleza kumzimba we-valve ngenxa yokuguquguquka koxinzelelo lombhobho, ukwakhiwa kwe-compact kunye nokusetyenziswa ngokukhuselekileyo.
Ivalve yefluorine inezi zibonelelo zilandelayo:
1. Ineenzuzo zesakhiwo esilula, ukuveliswa kunye nokulungiswa okufanelekileyo.
2. I-stroke esebenzayo incinci, ivule kwaye ivale ixesha elifutshane.
3. Ukutywinwa okulungileyo, umphezulu wokutywina phakathi kwamandla okubetha kancinci, ixesha elide lokuphila.
Iziphene zevalve yefluorine zimi ngolu hlobo lulandelayo:
1. Ukumelana nolwelo, amandla afunekayo ukuvula nokuvala enkulu.
2. Musa ukusebenzisa ngamaqhekeza, i-viscosity, i-coke elula ukuya ephakathi.
3. Ulawulo olungekho mgangathweni.
