I-GB cast steel Trunnion ball valves :Ukuhlaziywa okujulile kwesakhiwo nezici
I-valve yebhola elimisiwe elijwayelekile kazwelonke iyinsimbi esetshenziswa kabanzi ezinhlelweni zamapayipi ezimboni. Izindinganiso zayo zokuklama zihambisana nezindinganiso zikazwelonke zaseShayina futhi zinezici ezithile zesakhiwo kanye nezinzuzo zokusebenza. Okulandelayo yisingeniso esiningiliziwe sevalvu yebhola emisiwe yensimbi ejwayelekile kazwelonke:
1. Izici zesakhiwo:
-Isici esiyinhloko se-valve yebhola engaguquki ukuthi ibhola lilungisiwe futhi alikwazi ukunyakaza, futhi ukushintshwa kutholakala ngokuhamba kwesihlalo se-valve. Lo mklamo wenza lula ukwakheka kwe-valve, okwenza umsebenzi uzinze futhi uthembekile.
-Ukusetshenziswa kwezinto ezibonakalayo zensimbi kuthuthukisa ukumelana nokucindezela kanye nokumelana nokugqoka kwe-valve, okwenza kube kulungele uhla olubanzi lwezindawo zokusebenza.
2. Izinto zokwakha eziyinhloko:
-Izingxenye eziyinhloko zensimbi yensimbi ejwayelekile kazwelonke ama-valve amabhola ahleliwe ahlanganisa i-carbon steel, insimbi engagqwali, njll. Ukukhethwa kwalezi zinto kungalungiswa ngokuvumelana nezimo zangempela zokusebenza ukuze kuhlangatshezwane nezidingo ezahlukene zokusetshenziswa.
3. Izindawo zokufaka izicelo:
-Ngenxa yokusebenza kwayo okuhle kakhulu nokuthembeka, amavalvu ebhola amisiwe ajwayelekile kazwelonke asetshenziswa kakhulu ezinhlelweni zamapayipi ezimbonini ezifana ne-petroleum, amakhemikhali, negesi yemvelo ukulawula ukuhamba kwemidiya.
4. Izindinganiso zokwenza:
-Ukuklama, ukukhiqizwa, nokuhlolwa kwalesi valve yebhola kwenziwa ngokuhambisana namazinga kazwelonke afana ne-GB/T12237, ukuqinisekisa ikhwalithi nokusebenza komkhiqizo.
5. Ukunakekela nokugcina:
-Hlola njalo isimo sokusebenza se-valve, uhlanze ukungcola okuqoqiwe ngesikhathi, futhi ugcine ukuhlanzeka kwe-valve.
-Kuma-valve angasetshenzisiwe isikhathi eside, imisebenzi yokuvula nokuvala njalo kufanele yenziwe ukuze kuvinjwe ibhola ukuthi linamathele esihlalweni se-valve.
Kafushane, i-valve yebhola elimisiwe elijwayelekile likazwelonke lidlala indima ebalulekile emikhakheni ehlukahlukene yezimboni ngenxa yesakhiwo sayo esiyingqayizivele nokusebenza okuphakeme. Ukuqonda izici zayo eziyisisekelo nezindlela zokusebenzisa kungasiza ukusebenzisa kangcono lesi sisetshenziswa, sithuthukise ukusebenza kahle kokukhiqiza nokuphepha.
