Ukubaluleka kweeValve zoLwandle ezikwiBhodi
Ngaphakathi kwinqanawa, iivalvu zasemanzini ziyinxalenye ebalulekileyo phantse kuzo zonke iinkqubo ezinkulu, kuquka iinkqubo ze-ballast, iinkqubo ze-bilge, iinkqubo zeoyile yepetroli, iinkqubo zokupholisa amanzi olwandle, iinkqubo zokulwa nomlilo, kunye neenkqubo zokuphatha imithwalo. Injongo yazo ephambili kukulawula, ukwahlula, okanye ukulawula ukuhamba kolwelo kunye neegesi, ukuqinisekisa ukuba inkqubo nganye isebenza ngokukhuselekileyo nangokufanelekileyo phantsi kweemeko ezinzima zaselwandle.
Ngokungafaniyo neevalvu ezisetyenziswa kwimizi-mveliso ngokubanzi, iivalvu zasemanzini zenzelwe ukunyamezela iimeko ezinzima, kubandakanya ukugqwala kwamanzi anetyuwa, uxinzelelo oluphezulu, ukutshintsha kobushushu, kunye nokungcangcazela okuqhubekayo. Ngenxa yoko, iivalvu zasemanzini zenziwa ngokunamathela ngokungqongqo kwimigangatho yamazwe ngamazwe kwaye zihlala zifuna isiqinisekiso esivela kwiinkampani ezidumileyo zokwahlukanisa.
Iindidi eziqhelekileyo zeeValve zaseLwandle
Iindidi ezininzi zeevalvu zaselwandle zixhaphakile kwishishini laselwandle, nganye yenzelwe imisebenzi ethile:
Iivalvu zeSango
Iivalvu zesango zihlala zisetyenziselwa ukulawula ukuvulwa/ukuvalwa apho kufuneka ukuxhathisa ukuhamba kwamanzi okuncinci. Zifaneleke ngakumbi kwiinkqubo ezifuna ukuhamba ngokupheleleyo okanye ukuvalwa ngokupheleleyo, njengemibhobho ye-ballast kunye namanzi olwandle.
Iivalvu zeGlobe
Iivalvu zeglobe zilungele ukulawula ukuhamba kwamanzi kunye noxinzelelo. Zifumaneka rhoqo kwioyile yepetroli, kwioyile yokuthambisa, nakwiinkqubo zamanzi okupholisa apho ulawulo oluchanekileyo luyimfuneko.
Iivalvu zeBhola
Ziyaziwa ngokusebenza kwazo ngokukhawuleza nangokuvala kakuhle, iivalvu zebhola zisetyenziswa kakhulu kwiinkqubo zepetroli, igesi kunye namanzi. Ulwakhiwo lwazo oluncinci kunye nokuqina kwazo kunegalelo ekuthandweni kwazo kwiindawo zanamhlanje zokufakelwa kweenqanawa.
Iivalvu zebhabhathane
Iivalvu zebhabhathane zibonakaliswa bubukhaphukhaphu bazo, uyilo lwazo lulula, kunye nokusebenza lula. Zisetyenziswa rhoqo kwimibhobho emikhulu, kuquka iinkqubo ze-ballast kunye namanzi olwandle.
Iivalvu zokujonga (iivalvu ezingabuyisiyo)
Iivalvu zokujonga zisebenza ukuthintela ukuhamba okungasemva, ngaloo ndlela zikhusela iimpompo nezixhobo ezibalulekileyo ekonakaleni okunokwenzeka. Zizinto ezibalulekileyo kwiinkqubo ze-bilge, i-ballast, kunye neenkqubo zokukhupha umoya.
Iivalvu zoKhuseleko kunye noNcedo
Ezi valve zenzelwe ukukhupha uxinzelelo olugqithisileyo ngokuzenzekelayo, ngaloo ndlela ziqinisekisa ukhuseleko lwenkqubo kunye nokuthotyelwa kwemigaqo yolwandle.
Izixhobo kunye neMigangatho
Iivalvu zasemanzini zihlala ziveliswa ngezinto ezifana nentsimbi ephosiweyo, intsimbi ethambileyo, intsimbi yekhabhoni, intsimbi engatyiwayo, ibronze, kunye nee-alloys zekopolo. Ukukhetha izinto kuxhomekeke ekusetyenzisweni, uhlobo lolwelo, uxinzelelo, kunye nobushushu.
Ukuqinisekisa ukhuseleko kunye nokuthembeka, iivalvu zasemanzini kufuneka zilandele imigangatho yamazwe ngamazwe efana ne-JIS, i-DIN, i-ANSI, kunye ne-GB, kwaye kusenokufuneka imvume evela kwiinkampani zokwahlulahlula ezifana ne-ABS, i-DNV, i-LR, i-BV, i-CCS, kunye ne-NK. Ukusebenzisa iivalvu eziqinisekisiweyo akuqinisekisi nje kuphela ukuthotyelwa kwemithetho kodwa kunciphisa iindleko zokugcinwa kunye neengozi zokusebenza kulo lonke ixesha lohambo lwenqanawa.
