Iivalvu zidlala indima ebalulekileyo kukhuseleko kunye nokusebenza kweenqanawa zasemanzini. Ukususela ekulawuleni ukuhamba kolwelo kwiinkqubo zemibhobho ukuya ekulawuleni imisebenzi ebalulekileyo ekwinqwelo efana nokukhupha i-bilge, ukuhanjiswa kwepetroli, kunye nokukhusela umlilo, iivalvu zasemanzini zizinto ezibalulekileyo ezifuna ingqalelo rhoqo. Kodwa wazi njani ukuba lixesha lokuba uzihlole?Nantsi indlela yokufumanisa ukuba iivalvu zesikhephe sakho zifuna ukuhlolwa ngokucokisekileyo na—kwaye kutheni kubalulekile.
1. Ukugqwala okanye umhlwa obonakalayo
Imeko-bume yolwandle inzima, kwaye nee-alloys ezimelana nokugqwala zinokonakala ngokuhamba kwexesha. Ukuba ubona umhlwa okanye imingxuma kwimizimba yeevalvu, iziphatho, okanye iiflanges, luphawu olucacileyo lokuba ivalvu isenokuba sengozini. Ukuvezwa kwamanzi anetyuwa kukhawulezisa ukugqwala, okunokukhokelela ekuvuzeni okanye ekusileleni kweevalvu.
2. Umsebenzi oqinileyo okanye oxinzelelweyo
Iivalvu ezinzima ukuzijika, ezenza ingxolo ekhalayo, okanye ezingakwaziyo ukumelana nokusebenza zinokuba zibambeka ngaphakathi ngenxa yokuqokelelana kwenkunkuma, ukungabikho kokuthambisa, okanye ukuguguleka koomatshini. Ivalvu engavulekiyo okanye engavali kakuhle inokubangela iingozi ezinkulu zokusebenza—ingakumbi kwiinqwelo-moya okanye kwiinkqubo zokupholisa iinjini.
3. Ukuvuza okanye ukuvuza okungaqhelekanga
Nakuphi na ukuvuza okujikeleze isiqu sevalvu, iflange, okanye i-gasket akufanele kungananzwa. Nokuba ukuvuza okuncinci kunokubonisa ukuwohloka kwesihlalo sangaphakathi okanye ukonakala kwesitywina. Iinkqubo zepetroli ezikwinqwelo, iivalvu ze-ballast, kunye nemigca yokuhambisa amanzi acocekileyo kufuneka zingavuzi ngokupheleleyo ukuze kuthintelwe imiba yokhuseleko nokusebenza kakuhle.
4. Amanqanaba okuhamba komoya angangqinelaniyo
Ukuba iinkqubo zakho ezikwinqwelo azifumani ukuhamba kwamanzi, komoya, okanye kweoyile rhoqo, ivalvu evalekileyo okanye engasebenzi kakuhle inokuba yimbangela. Iivalvu ezingavulekiyo okanye ezingavalekiyo ngokupheleleyo zinokuthintela okanye zitshintshe ngokungacwangciswanga amazinga okuhamba—okunokuchaphazela ukupholisa injini, i-HVAC, okanye iinkqubo zokucima umlilo.
5. Imbali yoBudala beValve kunye noLondolozo
Njengazo zonke izinto ezisetyenziswa ngoomatshini, iivalvu zasemanzini zinobomi benkonzo. Ukuba awukhumbuli ixesha lokugqibela ivalvu ilungiswa ngalo—okanye ukuba sele kudlule iminyaka eliqela ukususela ekufakweni kwayo—lixesha lokuhlola. Ukusetyenziswa rhoqo okanye ukusebenza kwiindawo eziyingozi (ezifana neevalvu ze-ballast okanye iivalvu ezivala ngokukhawuleza kumagumbi enjini) kunciphisa ubomi bazo.
6. Iingxolo Ezingaqhelekanga
Isandi sokubetha umlozi, ukurhawuzelela, okanye ukungqongqoza xa ivalvu isetyenziswa sinokubonisa umonakalo wangaphakathi, ukuxinana kwesisu, okanye iingxaki zoxinzelelo. Ezi ngxolo zihlala zenzeka kwiivalvu zokukhupha umoya, kwiivalvu ezinciphisa uxinzelelo, okanye kwiivalvu zokunceda xa kukho ukuguguleka kwesihlalo okanye kwidiski.
7. Utshintsho kuxinzelelo lwenkqubo
Ukwehla koxinzelelo okanye ukunyuka kwesantya kwiinkqubo ezidityaniswe neevalvu—ezifana nokungena kwamanzi olwandle okanye imigca yepetroli—kunokuthetha ukuba ivalvu ayivali kakuhle. Sebenzisa iigeyiji zoxinzelelo ukujonga ukuguquguquka nokuqinisekisa ukuba ivalvu igcina uxinzelelo olusebenzayo oluchanekileyo na.
8. Iimfuneko zoMhloli woLwandle okanye uMbutho woHlelo
Ukuba inqanawa yakho ihlolwa minyaka le ligunya lolwandle (njenge-DNV, i-ABS, i-LR, i-BV, okanye i-CCS), kuya kufuneka ubonise ukusebenza kakuhle kweevalvu ezibalulekileyo—ingakumbi ezo zinxulumene neenkqubo ze-bilge, ukucima umlilo, kunye nokuphathwa kwepetroli. Ukuhlolwa kwangaphambili kokuhlolwa kufuneka kuquke uvavanyo lweevalvu.
