Ukuntywila nzulu kwiiValve zaseLwandle

Kwihlabathi elinzima lokwakha iinqanawa kunye nobunjineli baselwandle,iivalvuazikho nje izinto ezilula zokuvalaZizinto ezibalulekileyo zolawulo eziqinisekisa ukhuseleko, ukusebenza kakuhle, ukuthotyelwa kokusingqongileyo, kunye nokuthembeka kokusebenza kuyo yonke imigudu yobomi benqanawa. Ukusuka kwiinkqubo zamanzi ezilungelelanisiweyo ukuya kwiintambo zokubonelela ngepetroli, ukusuka kwiinethiwekhi zokucima umlilo ukuya kwiipayipi zegumbi leenjini, iivalvu zasemanzini zisebenza phantsi kweemeko ezinzima ezifuna ukusebenza okugqwesileyo.

Kutheni iiValve zaseLwandle zahlukile kwiiValve zeMveliso

Iindawo zaselwandle zinemingeni engaqhelekanga efunyanwa kwiindawo zoshishino eziqhelekileyo

• ①Ukuvezwa rhoqo emanzini olwandle, ityuwa etshizwayo, kunye nokufuma

• ②Ukungcangcazela kunye nokothukakwiinjini kunye namaza

• ③Iimfuno zoluntu zokuhlelwa ngokungqongqo(i-DNV, i-ABS, i-LR, i-BV, njl.njl.)

• ④Ukufikelela okulinganiselweyo kulondolozoxa iinqanawa zisebenza

• ⑤Iingozi eziphezulu zokhuseleko kunye nokusingqongileyo, ngakumbi kwiinkqubo zepetroli kunye ne-ballast

Ngenxa yoko, iivalvu zasemanzini kufuneka zibe nezinto ezimelana nokugqwala, ukuvala okuqinileyo, uyilo oluncinci, kunye nokuthembeka okuqinisekisiweyo.
