Ziziphi iimpawu zeevalvu zeplagi?
I-1, umzimba wevalve yevalve yeplagi idityanisiwe, uyilo olunyuswe phezulu, ulwakhiwo olulula, ulondolozo olufanelekileyo lwe-intanethi, akukho ndawo yokuvuza kwevalvu, inkxaso ephezulu yenkqubo yombhobho.
2, i-medium kwinkqubo yeekhemikhali inomhlwa owomeleleyo, kwindawo yoshishino lweekhemikhali, ihlala ibona umzimba wevalve ugxunyekwe phakathi, ufakwe kwivalvu kwinkqubo yekhemikhali, umzimba wevalvu kufuneka ube nokumelana okuqinileyo kunye ne-intergranular. ukumelana nomhlwa, umzimba wevalve yevalve yeplagi ukwinqanaba eliphezulu lokuphoswa, umgangatho wokuphosa ukwibakala II, ukuchaneka kwibakala V.
I-3, iindawo ezilula zangaphakathi, iindawo zokuvula kunye nokuvala ukuba inkuku igutyungelwe ngokupheleleyo yi-bushing, i-valve yomzimba kunye neqhude ngaphandle kokunxiba, i-bushing elula yezoqoqosho kunye nokutshintshwa kwetywina eliphezulu kunokugqitywa ukugcinwa kwevalve kunye nohlaziyo, inokufikelela kwiimfuno zokusetyenziswa kwexesha elide le-300 ℃. , kwaye ungowoluhlu olufanayo lwentsimbi yokutywina ivalve yebhola inenzuzo enkulu yokhuphiswano.
I-4, yonke indawo yokucubungula kuphela indawo ephezulu kunye ne-flange, ezinye iindawo zonke zibunjwa ngexesha elinye, akukho nkqubo ngaphakathi kumzimba we-valve, xa kuthelekiswa ne-valve yebhola inenzuzo yesibonelelo esisezantsi, xa izinto zi-INCONEL, i-MONEL. , I-Hastelloy kunye nezinye izinto ezikhethekileyo, inenzuzo ecacileyo yexabiso.
