Xa kufikwa kwiinqanawa,iivalvuazizonxalenye nje kuphela. Zizixhobo zokhuseleko. Ivalvu enengxaki ingathetha ixesha lokungasebenzi, iindleko eziphezulu, okanye neengozi ezinkulu elwandle. Yiyo loo nto ukujonga umgangatho weevalvu zaselwandle ngaphambi kokuba zifakwe kubaluleke kangaka. Kodwa wazi njani ukuba ivalvu iyahlangabezana nemigangatho efanelekileyo? Masiyihlalutye.
Jonga izixhobo
Ivalvu yolwandle iveliswa emanzini olwandle, uxinzelelo, kunye nokuguguleka rhoqo. Oko kuthetha ukuba impahla kufuneka ibe yomelele kwaye ingagqwali. Intsimbi engatyiwayo, ubhedu, kunye nee-alloys ezikhethekileyo zizinto eziqhelekileyo. Jonga ukuba umzimba wevalvu kunye ne-trim ziyahambelana na nemigangatho yenkqubo yakho. Ukuba isinyithi sivakala silula okanye sibonakala singalingani, sisenokungafaneleki kwinkonzo yolwandle.
Hlola izatifikethi
Iivalvu zasemanzini ezithembekileyo zihlala ziza nezatifikethi. Khangela imvume evela kwiinkampani zokwahlulahlula ezifana ne-DNV, i-LR, i-ABS, okanye i-BV. Ezi zatifikethi ziqinisekisa ukuba ivalvu ivavanyiwe ukuba isetyenziswe elwandle. Ngaphandle kwesatifikethi esifanelekileyo, kwanevalvu eyakhiwe kakuhle isenokungahlangabezani neemfuno zokhuseleko ebhodini.
Jonga umsebenzi
Ivalvu esemgangathweni ophezulu ibonisa umgangatho wayo kwiinkcukacha. Umphezulu kufuneka ube mpuluswa, ungabi nazimfanta, iimbobo, okanye imiphetho erhabaxa. Imisonto mayicoceke kwaye ibe chanekileyo. Iiflange kufuneka zibe tyaba. Ukugqitywa kakubi kudla ngokuthetha ukusebenza kakubi kamva, ingakumbi xa ucinezelekile.
Vavanya ukutywinwa
Enye yezona zinto zibalulekileyo kukujonga ukusebenza kokuvala. Ivalvu evuzayo iyingozi elwandle. Uvavanyo loxinzelelo lomoya kunye nolwe-hydrostatic ziindlela eziqhelekileyo zokujonga oku. Ukuba kunokwenzeka, jonga iingxelo zovavanyo ezibonelelwe ngumvelisi. Kwezinye iimeko, unokufuna ukwenza uvavanyo loxinzelelo ngokwakho ngaphambi kokuba ufake ivalvu ebhodini.
Vavanya uMsebenzi
Vula kwaye uvale ivalvu ngesandla okanye nge-actuator yayo. Ifanele ihambe kakuhle ngaphandle kokunamathela okanye ukugawula. Ukuba ivakala iqinile okanye ingalingani, ivalvu inokuba neengxaki zokulungelelanisa okanye zokulungisa. Kwiindawo zaselwandle, ukusebenza okulula nokuthembekileyo kubalulekile kukhuseleko kunye nokusebenza kakuhle.
Yazi uMboneleli
Okokugqibela, umgangatho awupheleli nje kwivalvu ngokwayo. Umalunga nenkampani esemva kwayo. Khetha umenzi onamava aqinisekisiweyo kwicandelo lezolwandle. Irekhodi elihle, iireferensi zehlabathi, kunye nenkxaso emva kokuthengisa konke oku kubonisa ukuba usebenzisana nomthengisi othembekileyo.
