Iivalvu zizinto ezibalulekileyo kwiinkqubo zemibhobho yenqanawa, zidlala indima ebalulekileyo ekulawuleni ukuhamba, uxinzelelo, kunye nesikhokelo solwelo kulo lonke inqanawa. Zinceda ekuqinisekiseni ukuba iinkqubo ezahlukeneyo, kubandakanya ukupholisa, i-ballast, ipetroli, kunye nokucima umlilo, zisebenza ngokufanelekileyo, ngokukhuselekileyo, nangokuthembekileyo. Ngaphandle kolawulo olufanelekileyo lweevalvu, iinkqubo zolwelo ezikwinqanawa ziya kuba neengxaki, ukuvuza, kunye nezinye iingozi zokhuseleko. Nantsi inkcazelo yendlela iivalvu ezinegalelo ngayo ekulawuleni uxinzelelo lokuhamba kunye nesikhokelo solwelo kwiinkqubo zemibhobho yenqanawa.
1. Ulawulo kunye noLawulo lokuHamba koMzila
- Iivalvu zeBhola: Zisetyenziselwa ulawulo olulula lokuvula/ukucima, ezi valve zivumela okanye ziyeke ukuhamba kolwelo kwinkqubo ngokuvula okanye ukuvala ngokupheleleyo. Zibaluleke kakhulu ekuhlukaniseni iinkqubo zokugcinwa okanye kwiimeko ezingxamisekileyo.
- Iivalvu zeGlobe: Ezi zenzelwe ukuvumela ukuthotywa okuchanekileyo kokuhamba kolwelo. Zihlala zisetyenziswa kwiindawo apho ulawulo lokuhamba kolwelo kufuneka luhlengahlengiswe rhoqo, njengakwiinkqubo zokupholisa okanye imigca yamafutha.
2. Ulawulo loxinzelelo
- Iivalvu Zokunceda: Ezi valve zivuleka ngokuzenzekelayo ukuze zikhulule uxinzelelo xa ludlula umda omiselweyo. Kwimeko yokwanda koxinzelelo, njengakwinkqubo yepetroli okanye kwimigca ye-hydraulic, ivalvu yokunceda ithintela umonakalo omkhulu ngokukhupha uxinzelelo olugqithisileyo ngokukhuselekileyo.
- Iivalvu Ezilawula Uxinzelelo: Ezi zisetyenziselwa ukugcina uxinzelelo oluhambelanayo ngaphakathi koluhlu oluthile, olubalulekileyo kwiinkqubo ezifuna uxinzelelo oluzinzileyo ukuze zisebenze ngokuchanekileyo, njengenkqubo yokupholisa yenjini okanye inkqubo yokuhambisa amafutha.
3. Ulawulo lokuhamba kwemiyalelo
- Iivalvu zokujonga: Ezi zithintela ukubuya kwamanzi ngokuqinisekisa ukuba ulwelo luhamba kwicala elinye kuphela. Zibaluleke kakhulu ekuthinteleni ukuhamba okungasemva okunokonakalisa izixhobo okanye kuphazamise ukusebenza kwenkqubo. Umzekelo, kwiinkqubo ze-bilge okanye iinkqubo ze-ballast, iivalvu zokujonga zithintela amanzi olwandle ukuba angabuyeli enqanaweni.
- Iivalvu Ezineendlela Ezintathu Nezininzi: Ezi valve zenzelwe ukuhambisa ukuhamba kolwelo kwiindlela ezahlukeneyo. Umzekelo, zingasetyenziselwa ukutshintsha phakathi kwemigca eyahlukeneyo yepetroli okanye ukuhambisa amanzi okupholisa kwiindawo ezahlukeneyo zenjini.
4. Ukuzahlula kunye nokuCima
- Iivalvu zeSango: Ezi zihlala zisetyenziselwa iinjongo zokuvala ngokupheleleyo, apho kufuneka kumiswe ngokupheleleyo ukuhamba kolwelo. Kwiimeko ezingxamisekileyo okanye ngexesha lokulungiswa, iivalvu zesango zivumela ukwahlulwa kwamacandelo enkqubo yemibhobho yenqanawa.
- Iivalvu zebhabhathane: Zisetyenziswa rhoqo ukulawula ukuhamba kwamanzi amaninzi, iivalvu zebhabhathane zikwasetyenziswa nakwiinkqubo zokucima ngokukhawuleza. Uyilo lwazo oluncinci luvumela ukusebenza ngokukhawuleza kunye nokutywinwa okusebenzayo.
5. Ukhuseleko kwiimeko ezingxamisekileyo
- Iinkqubo zokuCima uMlilo: Iivalvu zilawula ukuhamba kwamanzi okanye iikhemikhali ezithintela umlilo ukuze zicinezele amalangatye xa kutsha. Ukusebenza ngokukhawuleza nangokuthembekileyo kwezi valve kubalulekile ekunciphiseni umngcipheko.
- Iivalvu Zokucima Umbane Ezingxamisekileyo: Ezi valve zenzelwe ukuvala ngokukhawuleza iinkqubo ezibalulekileyo, ezifana neentambo zepetroli okanye oomatshini, xa kukho imeko engxamisekileyo, ukuthintela umonakalo okanye ingozi engaphezulu.
6. Ukulawula Ukuhamba Kweenkqubo Ezikhethekileyo
- Iinkqubo zeBallast: Iivalvu zilawula ukuhamba kwamanzi olwandle angena naphuma kwiitanki ze-ballast, zinceda inqanawa ukuba ihlale izinze kwaye isasazeke kakuhle. Oku kubalulekile kwibhalansi yenqanawa, ingakumbi ngexesha lokulayisha okanye lokukhupha impahla.
- Iinkqubo Zokupholisa: Iivalvu zilawula ukuhamba kwamanzi kwiinkqubo zokupholisa zenqanawa ukuqinisekisa ukuba iinjini kunye nezinye iimatshini zihlala zikwiqondo lobushushu lokusebenza elikhuselekileyo.
- Iinkqubo zeFuel: Kwinkqubo yokuhambisa ifuel, iivalvu zilawula ukuhamba kwefuel ukusuka kwiitanki zokugcina ukuya kwiinjini, ziqinisekisa ukuba ifuel inikezelwa ngoxinzelelo kunye nesantya esifanelekileyo.
