Kwinqanawa, iinkqubo zokhuseleko azinyanzelekanga—zisindisa ubomi. Phakathi kwezi nkqubo,iivalvu zokuvala ngokukhawulezazidlala indima ebalulekileyo ekukhuseleni iinqanawa, abasebenzi, kunye nemithwalo kwimingcipheko yomlilo kunye nezikhukula. Zenzelwe ukuvala umbane okanye ioyile ngoko nangoko, iivalvu zokuvala ngokukhawuleza ziyinxalenye ebalulekileyo kubunjineli bezolwandle banamhlanje.
Impendulo ekhawulezileyo kwiimeko ezingxamisekileyo
Injongo ephambili yevalvu yokuvala ngokukhawuleza kukukhawuleza. Xa kutsha, kuvuza ipetroli, okanye kuqhekeke umbhobho, ezi valve zinokuvala ukuhamba kweoyile yepetroli okanye ioyile yokuthambisa kwimizuzwana embalwa. Oku kwahlukana ngokukhawuleza kuthintela ipetroli ekuphembeleleni umlilo kwaye kunciphisa kakhulu umngcipheko wokuqhuma.Ngokungafaniyo neevalvu ezisebenza ngesandla ezikwiindawo ezinobungozi, iivalvu ezivala ngokukhawuleza zinokusebenza kude, zivumela amalungu eqela ukuba enze ngaphandle kokungena kwiindawo eziyingozi.
Ukhuseleko loMlilo oluphuculweyo kwiBhodi
Iinjini zaselwandle zixhomekeke kakhulu kwiinkqubo zamafutha kunye nokuthambisa. Ukuba kuqhambuka umlilo kwigumbi leenjini, ukuhamba kwamafutha okungalawulwayo kunokuguqula ngokukhawuleza isiganeko esilawulekayo sibe yintlekele. Iivalvu zokuvala ngokukhawuleza ziyanceda:
-
①Nciphisa ukunikezelwa kwepetroli kwiinjini nakwiijenereyitha
-
②Nqanda ioyile ekusasazeni amadangatye
-
③Xhasa amaqhinga okulawula umlilo
Lo msebenzi ubaluleke kakhulu kwiindawo ezixineneyo apho umlilo usasazeka ngokukhawuleza.
Ukuthobela iMimiselo yeHlabathi yezoLwandle
Iivalvu zokuvala ngokukhawuleza aziyondlela ilungileyo nje kuphela—ziyindlelaimfuneko yomthethoImigangatho yamazwe ngamazwe efana nale:I-SOLAS (Ukhuseleko lobomi elwandle).Imigaqo ye-IMO.Imithetho yoluntu lokwahlulahlula (i-DNV, i-ABS, i-LR, i-BV, njl.njl.)
Kufuneka kufakwe iivalvu zokuvala ngokukhawuleza kwiitanki zeoyile yepetroli nakwiindawo zokuhambisa. Ukufakela iivalvu eziqinisekisiweyo kuqinisekisa ukuthotyelwa kwemithetho ngexesha lokuhlolwa kwaye kuthintela izohlwayo ezibizayo okanye ukulibaziseka kokusebenza.
Ukusebenza okukude nokungasebenzi kakuhle
Iivalvu zokuvala ezikhawulezayo ziyilwe ngolu hlobo lulandelayo:Ukusebenza kwe-mechanical, pneumatic, okanye hydraulic kude.Iindlela zokuvala ezifakwe entwasahlobo okanye ezincediswa ngumxhuzulane
Oku kuthetha ukuba ivalvu iya kuvala ngokuzenzekelayo xa umbane ulahlekile okanye ulawulo lungaphumeleli, nto leyo eyongeza umaleko okhuselekileyo. Nokuba phantsi kweemeko ezinzima zaselwandle—ukungcangcazela, ubushushu, okanye ukugqwala—ivalvu ihlala ithembekile.
Ukunciphisa iingozi zeNdalo nezokusebenza
Ukuvuza kwepetroli elwandle kunokubangela umonakalo omkhulu kwindalo esingqongileyo kwaye kukhokelela kwiintlawulo ezinkulu. Iivalvu zokuvala ngokukhawuleza ziyanciphisa:Ukuchitheka kweoyile.Ixesha lokungasebenzi koomatshini.Iindleko zokulungisa nezokucoca
Ngokuzihlukanisa ngokukhawuleza iindawo ezonakeleyo, amaqela anokulawula ngcono iinkqubo ezikwinqwelo.
Ukuxhasa Ukugcinwa Nokulungiswa Okukhuselekileyo
Ngexesha lokugcinwa, iivalvu ezivala ngokukhawuleza zivumela abaqhubi ukubahlukanisa iitanki zepetroli kunye nemibhobho ngokukhuselekileyo, kunciphisa umngcipheko wokuphuma ngengozi. Oku kwenza uhlolo oluqhelekileyo kunye nokulungiswa okungxamisekileyo kukhuseleke kwaye kube luncedo ngakumbi.
