Amathiphu okuthenga amavalvu Uhlu lwamavalvu adingekayo ezitshalweni ezinkulu zamandla ashisayo

Ngokuvamile, intengo yemakethe ye-valve yezwe lethu izinzile, nakuba ikhuphuka kancane futhi iwa njalo ngonyaka, kodwa ububanzi buncane kakhulu.
Izinkinga ezinkulu emakethe yama-valve yilezi:
1. Abanye o-opharetha bathenga ama-valve ngaphandle kwegama lemboni nekheli, futhi baphrinte izitifiketi zabakhiqizi kanye namabhizinisi ama-valve afanelekayo, okubangela ukulimala okukhulu esithunzini samabhizinisi ama-valve aqeqeshiwe.
Okwesibili, ama-valve avuselelwe, abanye o-opharetha ngokusebenzisa okwesibili ngemva kokupenda kabusha ama-valve asetshenzisiwe, ukuletha izingozi ezinkulu zokuphepha kukhwalithi yephrojekthi.
Ngakho-ke kufanele kuqashelwe ekukhetheni i-valve efanele ngenjongo yakho. Ukuze ugweme ukungaqondakali, imithetho kufanele yenziwe ku-valve ngayinye. NGESIKHATHI SOKUBUZA noma SOKU-ODA, INCAZELO EFANELE YEMVAVVU EDINGEKAYO KUFANELE Inikezwe.
Ukukhetha USIZE VALVE kufanele kunqume Usayizi NOMINAL wepayipi lapho i-valve ixhunywe khona. Impahla yevalvu Izinto ezilandelayo kufanele zicatshangelwe lapho kunqunywa impahla yevalvu efanele:
I-fluid medium okufanele ilawulwe yi-valve
Ibanga lokushisa le-fluid medium
Uhla lwezingcindezi i-valve engaphansi kwayo
Izimo zezulu ezingase zithinte ukusebenza kwevalvu
Ukucindezela okungajwayelekile okungenzeka noma ingcindezi i-valve engaphansi kwayo
Amazinga okuphepha noma izinqubo zamapayipi okufanele kuhlangatshezwane nazo
Umsebenzi wokulawula i-valve. I-VALVE DESIGN ngayinye YAKHELWE UKWENZA UMSEBENZI OTHILE. UNGALINDELEI IVAVVU EYODWA UKWENZA YONKE IMISEBENZI KUHLELO LOKUPHAMBANA.
Ingcindezi – izinga lokushisa. Ukuze uhlangabezane nezidingo ezingokoqobo, qaphela ngokukhethekile ukucindezela - izinga lokushisa kwe-valve elidingekayo. KUFANELE KUQAPHELE OKUKHETHEKILE EKUVALWENI KANYE NEZINTO ZEGASKET, EZITHOBA KAKHULU ISILINGANISO SOMSINDO-MLINGANISO WEMVAVVU. Cacisa izinto zokuvala kanye nezinto zokuwisa imvula ngokwezidingo zangempela zokuhlangabezana noma ezingcono kunezidingo zangempela.
I-valve nemodi yokuxhuma. Ubuqotho boHLELO lwamapayipi, ukugcinwa kwesimiso sesikhathi esizayo, izici ezivimbela ukubola, ukuhlanganiswa kwenkundla, isisindo nokuphepha YIZO ZONKE IZINTO OKUMELE ZIGCATSHULWE UKUZE kunqunywe ukuthi i-valve ixhunywe kanjani kumapayipi.
Imodi yokusebenza noma indlela yokusebenza Khetha imodi yokusebenza efanele noma indlela yokusebenza ngokuya ngohlobo lwevalvu, ubukhulu, ingcindezi, izinga lokushisa, indawo yokufaka nezinye izici.
Ukuhleleka kwama-valve
UMA U-ODA AMAVAVAVU, SICELA UNIKEZE NGEDATHA ELANDELAYO UKUZE UGWEME UKUPHINDA OKUNGEZIDINGO KANYE NOKUBAMBEZEKA FUTHI UQINISEKISE UKUTHI IVAVA OYITHENGAYO IYIKHO Impela OYIDINGAYO.
1. Usayizi wevalvu
2. Izinto ezisetshenziswayo zokucindezela: ukusakaza kanye nezinto zokwakha.
3. Uhlobo lwe-valve: i-valve yesango, i-globe valve, i-valve yokuhlola, i-butterfly valve, i-valve yebhola, njll.
4. Imodi yokuxhumeka kwetheminali, uma imodi yokuxhuma i-welding, ubukhulu bodonga lwepayipi yokuxhuma kufanele bunikezwe; Uma uxhumano luvulekile, indawo ye-flange noma isiphetho kufanele inikezwe.
5. Noma iyiphi impahla ehlukile ekucushweni okujwayelekile: izinto zokuvala, izinto ezimanzi, impahla yebhawodi, njll.
6. Noma yiziphi izesekeli: ungqimba lokuvikela i-asidi, idivayisi yokukhiya, ukusebenza kweketango, njll.
7. Ama-activator okwenziwa ngesandla noma amandla: Sicela ufake imininingwane yobuchwepheshe edingekayo.
8. Ukuze kube lula uku-oda, sicela uqinisekise imininingwane namamodeli.
