I-valve yebhola yensimbi eshiselwe ngokugcwele - Umnakekeli wamapayipi ezimboni
I-valve yebhola eshiselwe ngokugcwele, i-valve enesakhiwo sokuvala insimbi, isetshenziswa kabanzi ezinhlelweni zamapayipi ezimbonini ezifana ne-petroleum, igesi yemvelo, amakhemikhali, kanye ne-metallurgy. Uma iqhathaniswa nezindlela zokuxhuma ze-flange zendabuko, inezinzuzo ezifana nokufaka kalula, ukubekwa uphawu okuhle, nempilo ende yesevisi. Lesi sihloko sizokunikeza isingeniso esiningiliziwe sezimpawu nezindawo zokusebenzisa ama-valve ebhola ashiselwe ngokugcwele.
1. Izici zesakhiwo
I-valve yebhola ehlanganiswe ngokugcwele yenziwe ngensimbi engagqwali noma izinto zensimbi ezikwazi ukumelana nokushisa, ezinomklamo ohlanganisiwe ongadingi izingxenye zokulungisa eziveziwe, ukugwema inkinga yama-valve endabuko ejwayele ukugqwala ngenxa yesakhiwo sangaphandle. Idizayini yayo eyingqayizivele ye-dual sphere ingavimbela ngempumelelo ukuvuza okuphakathi kusuka ezinhlangothini zombili ze-valve, iqinisekise ukusebenza okuphephile nokuzinzile kwesistimu.
2. Inkambu yohlelo lokusebenza
Ama-valve amabhola ashiselwe ngokugcwele afaneleka kumasistimu wamapayipi anomfutho ophezulu, izinga lokushisa eliphezulu, nobubanzi obukhulu, ikakhulukazi ukuthutha izinto ezivuthayo neziqhumayo njengowoyela negesi yemvelo. Emkhakheni wobunjiniyela bamakhemikhali, i-metallurgy, namandla, ama-valve ebhola ashiselwe ngokugcwele nawo asesetshenziswe kabanzi, enikeza iziqinisekiso ezithembekile zokukhiqizwa kwezimboni.
3. Izinzuzo zezobuchwepheshe
1. Ukusebenza okuhle kakhulu kokuvala: I-valve yebhola eshiselwe ngokugcwele yamukela isakhiwo sokuvala insimbi, iqinisekisa ukuthi ukusebenza kokuvala kwe-valve kungcono kunezindlela zokuxhuma ze-flange zendabuko.
2. Izinga lokushisa eliphezulu nokumelana nokugqwala: Ivalvu yebhola eshiselwe ngokugcwele ingamelana namazinga okushisa afinyelela ku-300 ℃ futhi ine-asidi enhle ne-alkali ukumelana nokugqwala.
3. Ukufakwa kalula: I-valve yebhola eshiselwe ngokugcwele ayidingi i-welding noma i-bolt fastening, futhi ingafakwa ngokuyishisela ngokuqondile epayipini, konga kakhulu isikhathi sokufaka nezindleko.
4. Impilo ende yesevisi: Impilo yesevisi yamavalvu ebhola ashiselwe ngokugcwele yinde kakhulu kunaleyo yamavalvu endabuko, afinyelela emashumini ambalwa eminyaka noma ngaphezulu.
4. Isifinyezo
Amavalvu ebhola ashiselwe ngokugcwele asephenduke into ebaluleke kakhulu futhi ebalulekile ezinhlelweni zamapayipi ezimboni ngenxa yesakhiwo sawo esiyingqayizivele nokusebenza okuphakeme. Ekuthuthukisweni okuzayo, ngokuthuthuka kobuchwepheshe kanye nokukhula kwesidingo semakethe, ama-valve amabhola ashiselwe ngokugcwele azodlala indima ebalulekile emikhakheni eminingi, ehlinzeka ngezixazululo eziphephile nezisebenza kahle zokukhiqiza izimboni.
