A:Amavalvu okuphepha nezikali zokucindezela ziyizingxenye ezibalulekile zamajeneretha omusi, futhi angenye yeziqinisekiso zokuphepha zamajeneretha omusi.I-valve yokuphepha evamile iyisakhiwo sohlobo lwe-ejection.Lapho umfutho we-steam mkhulu kunomfutho olinganiselwe, i-valve disc izophushwa ivuleke.Uma i-disc ye-valve ishiya isihlalo se-valve, isitimu sizokhishwa esitsheni ngokushesha;i-gauge yokucindezela isetshenziselwa ukuthola ingcindezi yangempela ku-generator yesitimu.Ubukhulu bensimbi, opharetha ulungisa ukucindezela kokusebenza kwejeneretha ye-steam ngokwenani elibonisiwe legeji yokucindezela, ukuze kuqinisekiswe ukuthi i-generator yesitimu ingaqedwa ngokuphephile ngaphansi kwengcindezi yokusebenza evunyelwe.
Amavalvu okuphepha namageji omfutho yizisetshenziswa zamavalvu okuphepha, amavalvu okuphepha ayimpahla yokuvikela umfutho, kanti amageji omfutho angamathuluzi okulinganisa.Ngokwamazinga okusetshenziswa komkhumbi wengcindezi kazwelonke nezindlela zokulinganisa, ukulinganisa kufanele kube yimpoqo.
Ngokwemithethonqubo efanele, ivalvu yokuphepha izolinganiswa okungenani kanye ngonyaka, futhi isilinganiso somfutho sizolinganiswa njalo ezinyangeni eziyisithupha.Ngokuvamile, yisikhungo sokuhlola okukhethekile sendawo kanye nesikhungo se-metrology, noma ungathola i-ejensi yokuhlola yenkampani yangaphandle ukuze uthole ngokushesha umbiko wokulinganisa wevalvu yokuphepha negeji yokucindezela.
Ngesikhathi senqubo yokulinganisa yama-valve okuphepha kanye nezikali zokucindezela, umenzi udinga ukunikeza ulwazi olufanele, ngale ndlela elandelayo:
1. Ukulinganisa amavalvu okuphepha kudinga ukuhlinzeka: ikhophi yelayisense yebhizinisi lomsebenzisi (enesigxivizo esisemthethweni), amandla ommeli, uhlobo lwevalvu yokuphepha, imodeli yevalvu yokuphepha, ingcindezi yokusetha, njll.
2. Ukulinganisa kwegeji yokucindezela kudinga ukuhlinzeka: ikhophi yelayisense yebhizinisi lomsebenzisi (enesigxivizo esisemthethweni), amandla ommeli, nemingcele yegeji yengcindezi.
Uma umkhiqizi ecabanga ukuthi kunzima ukwenza ukulinganisa yedwa, zikhona nezikhungo emakethe ezingamenzela ukuhlolwa.Udinga kuphela ukunikeza ilayisense yebhizinisi, futhi ungakwazi ukulinda kalula i-valve yokuphepha kanye nombiko wokulinganisa wegeji yokucindezela, futhi awudingi ukuziqhuba wedwa.
Ngakho-ke unganquma kanjani ukucindezela okuphelele kwe-valve yokuphepha?Ngokusho kwemibhalo efanelekile, ukucindezela okuhleliwe kwe-valve yokuphepha kwanda izikhathi ezingu-1.1 ukucindezela kokusebenza kwemishini (ukucindezela okubekiwe akufanele kudlule ukucindezela kokuklama kwemishini) ukuze kunqunywe ukunemba kokucindezela kwe-valve yokuphepha.
