Uma kukhulunywa ngemikhumbi,amavalvuakuzona nje izingxenye. Ziyizinto zokuphepha. Ivalvu enephutha ingasho isikhathi sokungasebenzi, izindleko eziphakeme, noma ngisho nezingozi ezinkulu olwandle. Yingakho ukuhlola ikhwalithi yamavalvu asolwandle ngaphambi kokufakwa kubaluleke kangaka. Kodwa wazi kanjani ukuthi ivalvu ihlangabezana nezindinganiso ezifanele? Ake sixoxe ngakho.
Bheka Izinto Ezisetshenziswayo
Ivalvu yasolwandle ivezwa emanzini olwandle, ingcindezi, kanye nokuguguleka okuqhubekayo. Lokho kusho ukuthi impahla kumele ibe namandla futhi imelane nokugqwala. Insimbi engagqwali, ithusi, kanye nezinsimbi ezikhethekile kuyizinketho ezivamile. Hlola ukuthi umzimba wevalvu kanye nokusika kuyafana yini nemininingwane yesistimu yakho. Uma insimbi izwakala ilula noma ibukeka ingalingani, ingase ingafaneleki isevisi yasolwandle.
Hlola Izitifiketi
Amavalvu asolwandle athembekile ahlala eza nezitifiketi. Funa izimvume ezivela ezinhlanganweni zokuhlukanisa njenge-DNV, LR, ABS, noma i-BV. Lezi zitifiketi ziqinisekisa ukuthi ivalvu ihlolwe ukusetshenziswa kolwandle. Ngaphandle kwesitifiketi esifanele, ngisho nevalvu eyakhiwe kahle ingase ingahlangabezani nezidingo zokuphepha ebhodini.
Hlola Umsebenzi
Ivalvu esezingeni eliphezulu ikhombisa ikhwalithi yayo ngemininingwane. Ubuso kufanele bube bushelelezi, kungabi nemifantu, ama-pores, noma imiphetho erhabaxa. Imicu kufanele ihlanzeke futhi inembile. Ama-flange kufanele abe yisicaba. Ukuqeda okubi kuvame ukusho ukusebenza kabi kamuva, ikakhulukazi ngaphansi kwengcindezi.
Hlola Ukuvalwa
Okunye kokuhlola okubaluleke kakhulu ukusebenza kokuvala. Ivalvu evuzayo iyingozi olwandle. Ukuhlolwa kwengcindezi yomoya kanye nokwe-hydrostatic kuyindlela evamile yokuhlola lokhu. Uma kungenzeka, buyekeza imibiko yokuhlola enikezwe umenzi. Kwezinye izimo, ungase ufune ukwenza ukuhlolwa kwengcindezi ngokwakho ngaphambi kokufaka ivalvu ebhodini.
Hlola Ukusebenza
Vula futhi uvale ivalvu ngesandla noma nge-actuator yayo. Kufanele ihambe kahle ngaphandle kokunamathela noma ukugaya. Uma izwakala iqinile noma ingalingani, ivalvu ingaba nezinkinga zokuqondanisa noma zokulungisa. Ezindaweni zasolwandle, ukusebenza okulula nokuthembekile kubalulekile kokubili ekuphepheni nasekusebenzeni kahle.
Yazi Umhlinzeki
Okokugcina, ikhwalithi ayigcini nje ngevalvu ngokwayo. Imayelana nenkampani engemuva kwayo. Khetha umenzi onolwazi oluqinisekisiwe emkhakheni wezasolwandle. Irekhodi eliqinile, izinkomba zomhlaba wonke, kanye nokusekelwa kwangemva kokuthengisa konke kubonisa ukuthi usebenzelana nomhlinzeki othembekile.
