Indlela Yokuhlola Nokuhlola Ama-Valve
Njengemishini ebalulekile yokulawula uketshezi, ama-valve asetshenziswa kabanzi emikhakheni eminingi efana ne-petroleum, imboni yamakhemikhali, kanye nogesi. Umkhiqizi wama-valve e-NSW uzohlaziya izinto eziyinhloko zeukuhlolwa kwe-valvekanye nokuhambisana kwazoamazinga okuhlola.
Incazelo yeValve
Amavalvu amadivayisi asetshenziselwa ukulawula ukugeleza, ingcindezi, izinga lokushisa kanye nezinye izilinganiso zoketshezi, futhi asetshenziswa kabanzi emishinini yezimboni, yezezindlu kanye neyasekhaya. Ngokusho kokusetshenziswa nemisebenzi ehlukene, amavalvu angahlukaniswa ngezinhlobo eziningi, njenge:
I-Valve yeSango: Vula futhi uvale isiteshi soketshezi ngokuphakamisa ipuleti lesango, elifanele izikhathi ezivuleke ngokuphelele noma ezivaliwe ngokuphelele.
I-Ball Valve: Lawula ukugeleza koketshezi ngokujikeleza ibhola, ngezinzuzo zokuvala kahle, isakhiwo esilula, kanye nokusebenza okulula.
I-Globe Valve: Lawula ukugeleza koketshezi ngokujikeleza isiqu sevalvu ukuze wenze idiski yevalvu ihambe phezulu naphansi, ngaleyo ndlela ushintshe usayizi wembobo yevalvu, efanele ukulawula nokunqamula uketshezi.
I-Butterfly Valve: Lawula ukugeleza koketshezi ngokujikeleza idiski (ipuleti lovemvane), elivame ukusetshenziswa ukulawula uketshezi emapayipini amakhulu.
Hlola i-Valve: Isetshenziselwa ukuvimbela ukubuyela emuva koketshezi, ngokuvamile kufakwa endaweni yokuphuma kwepompo noma epayipini loketshezi.
I-Valve Yokuphepha: Uma ingcindezi ohlelweni idlula inani elibekiwe, ivuleka ngokuzenzakalelayo ukuvimbela ukucindezeleka ngokweqile, okusetshenziselwa kakhulu ukuvikela ukuphepha kwemishini nezinhlelo.
Izinto eziyinhloko zokuhlola i-Valve
Ukuhlolwa kwamavalvu kubalulekile ukuqinisekisa ukuphepha nokuthembeka kwawo ezindaweni ezahlukene zokusetshenziswa. Okulandelayo yizinto eziyinhloko zokuhlolwa kwamavalvu kanye nezindinganiso zawo kanye nezindlela zokuhlola.
