I-valve yokushisa ephezulu ibhekisela ku-valve esebenza ngaphansi kwezimo zokushisa eziphakeme, ezisetshenziswa kakhulu ku-petroleum, imboni yamakhemikhali, i-metallurgy nezinye izimboni. Ngenxa yezinselele eziningi ekushintsheni kokusebenza kwezinto, ukuzinza kwesakhiwo nokubeka uphawu ezindaweni zokushisa okuphezulu, ukwakhiwa kwama-valve okushisa aphezulu kunzima. Lesi sihloko sizovela ebunzima bokukhiqiza i-valve ephezulu kanye nezidingo zobuchwepheshe zezici ezimbili zokuhlaziya.
Okokuqala, ubunzima bokukhiqiza
1. Ukukhethwa kwezinto ezibonakalayo: Ngaphansi kwemvelo yokushisa okuphezulu, ukusebenza kwezinto kulula ukushintsha, njengokumelana ne-oxidation, ukumelana nokugqoka, amandla nokunye. Ngakho-ke, ekukhiqizeni ama-valve okushisa aphezulu, kuyadingeka ukukhetha izinto ezisebenza kahle kakhulu zokushisa okuphezulu, njenge-superalloys, i-ceramics, izinto ezihlanganisiwe, njll.
2. Ukwakhiwa kwesakhiwo: I-valve yokushisa ephezulu isebenza endaweni yokushisa ephezulu, futhi ukwakheka kwayo kwesakhiwo kudinga ukucabangela ukunwetshwa kwe-thermal, ukuguqulwa kwe-thermal kanye nokucindezeleka kokushisa kanye nezinye izici zempahla ukuze kuqinisekiswe ukuthi i-valve inokusimama okuhle. kanye nokuvala ngaphansi kwezimo zokushisa eziphezulu.
3. Ubuchwepheshe bokufaka uphawu: ngaphansi kwemvelo yokushisa ephezulu, ukusebenza kwezinto zokufaka uphawu kuthinteka kalula, njenge-oxidation, ukugqoka njalonjalo. Ngakho-ke, lapho ukhiqiza ama-valve okushisa aphezulu, kuyadingeka ukusebenzisa izinto zokuvala ngokusebenza okuhle kakhulu kokuvala izinga lokushisa eliphezulu futhi wamukele isakhiwo sokuvala esinengqondo.
4. Inqubo yokukhiqiza: Izidingo zenqubo yokukhiqiza i-valve ephezulu yokushisa, njenge-welding, machining, ukuhlanganisa nezinye izinqubo zidinga ukulawulwa ngokuqinile ukuze kuqinisekiswe izinga nokusebenza kwe-valve.
2. Izidingo zobuchwepheshe
1. Amandla okushisa aphezulu: ama-valve okushisa aphezulu adinga ukuba namandla okwanele okushisa okuphezulu ukuze kuqinisekiswe ukuthi ngeke kube khona ukuguqulwa noma umonakalo ngaphansi kwezimo zokushisa eziphezulu.
2. Ukumelana ne-oxidation: izinto ezisetshenziswayo zamavalvu okushisa aphezulu zidinga ukumelana ne-oxidation kahle ukumelana nokugqwala kwe-oxidative ezindaweni zokushisa okuphezulu.
3. Ukumelana nokugqoka: Ama-valve okushisa aphezulu adinga ukumelana nokugqoka okwanele ukuqinisekisa ukuthi ngeke ahluleke ngenxa yokugqoka ngaphansi kwezimo zokushisa eziphezulu.
4. Ukuqina: ama-valve okushisa aphezulu adinga ukuba nokuqina okuhle ukuze kuqinisekiswe ukuthi ngeke kube khona ukuvuza ezindaweni ezishisa kakhulu.
5. Ukuzinza: ama-valve okushisa aphezulu adinga ukuzinza okuhle ukuze aqinisekise ukuthi angasebenza ngokujwayelekile ngaphansi kwezimo zokushisa eziphezulu.
Ukukhiqiza ama-valve okushisa aphezulu kunobunzima obuthile, isidingo sokunqoba ukukhethwa kwezinto ezibonakalayo, ukwakheka kwesakhiwo, ubuchwepheshe bokuvala uphawu, inqubo yokukhiqiza kanye nobunye ubunzima. Ngesikhathi esifanayo, i-valve yokushisa ephezulu idinga ukuhlangabezana nezidingo zobuchwepheshe zamandla okushisa aphezulu, ukumelana ne-oxidation, ukumelana nokugqoka, ukubekwa uphawu, ukuzinza nokunye ohlelweni lokukhiqiza ukuqinisekisa ikhwalithi nokusebenza kwe-valve.
