Iinqanawa zixhomekeke kwiintlobo ezininzi zeevalvu, kodwaiivalvu zesangoZihlala ziphakathi kwezona ntlobo zisetyenziswa kakhulu kwiipayipi zaselwandle. Ziphatha ukwahlulwahlulwa, ukuvalwa, kunye nolawulo olungxamisekileyo kwiinkqubo ezithwala amanzi olwandle, ipetroli, ioyile, amanzi e-bilge, amanzi e-ballast, kwanomphunga. Ngenxa yokuba iimeko zaselwandle zinzima, uyilo lweevalvu zesango ezahlukeneyo lusetyenziselwa ukulinganisa amanqanaba oxinzelelo, umngcipheko wokugqwala, kunye nemida yendawo. Ukuqonda iintlobo zeevalvu zesango laselwandle kunceda abanini beenqanawa, iinjineli, kunye nabathengi ukuba bakhethe imodeli efanelekileyo yokhuseleko kunye nobomi benkonzo ende.
1. Ivalvu yeSango leSitem esiKhulayo (Uhlobo lwe-OS&Y)
Olu lolunye lolona yilo luqhelekileyo olufumaneka kwiinqanawa. Xa ivalvu ivuleka, isiqu siyaphakama ngokubonakalayo. Xa ivala, isiqu siyehla. Olu hambo lulula lunika umqhubi umbono ocacileyo wesimo sevalvu. Iinjineli ezininzi zikhetha olu hlobo kwimigca ebalulekileyo kuba uphawu olubonakalayo lunciphisa iimpazamo zokusebenza.
Apho isetyenziswa khona:imibhobho yamanzi olwandle, unikezelo lwamanzi acocekileyo, ukupholisa injini, iinkqubo zeoyile yepetroli, imigca yomlilo.
Kutheni isebenza kakuhle kwiinqanawa:kulula ukuyigcina, ukutywina okuthembekileyo, kulungile kuxinzelelo oluphezulu.
2. Ivalvu yeSango leStem eliNgenakunyuka (Uhlobo lwe-NRS)
Apha, isiqu asinyuki siye phezulu. Isango lihamba ngaphakathi endaweni yoko. Ekubeni ukuphakama okuthe nkqo kuhlala kungaguquki, olu hlobo lufanelekile kwiindawo ezincinci—into yonke injineli yolwandle eyiqonda kakuhle.
Iindawo eziqhelekileyo:imigca yebhilge, iinkqubo ze-ballast, amagumbi okumpompa, iindawo ezinemida yokuphakama.
Inzuzo ephambili:uyilo olugcina indawo olunamandla okuvala afanayo noohlobo lwe-OS&Y.
3. Ivalvu yeSango leNsimbi yentsimbi
Iivalvu zesinyithi eziphosiweyo zisetyenziswa kakhulu kwinkonzo yamanzi olwandle anoxinzelelo oluphantsi kuba zingabizi kakhulu kwaye zihlala ixesha elide xa zikhuselwe ekungcoleni. Ziqhelekile kwiinqanawa ezininzi zorhwebo nezemithwalo.
Izicelo:iinkqubo eziphambili zomlilo, imigca yenkonzo yamanzi olwandle, imibhobho yenkonzo eqhelekileyo.
4. Ivalvu yeSango leBronze Marine
I-bronze isebenza kakuhle kakhulu emanzini olwandle. Iyamelana nokugqwala ngokwendalo, yiyo loo nto abakhi beenqanawa abaninzi besayithanda kakhulu kuneentambo ezinoxinzelelo oluphakathi.
Iindlela eziqhelekileyo zokusetyenziswa:Ukupholisa i-HVAC, iinkqubo zamanzi acocekileyo, iisekethe zamanzi okupholisa, imigca emincinci encedisayo.
5. Ivalvu yeSango leNtsimbi engaGciniyo
Xa kukho amaqondo obushushu aphezulu, iikhemikhali, okanye ulwelo olubolayo, intsimbi engagqwaliyo iba lolona khetho lubalaseleyo.SS316zibonelela ngokuchasana okugqwesileyo namanzi olwandle kunye neendawo ezihlaselayo.
Isetyenziswa kwi:imigca yeekhemikhali, iinkqubo zoxinzelelo oluphezulu, amanzi ashushu, iinkqubo zepetroli.
6. Ivalvu yeSango leMele (yeeNkqubo zoGutyulo lwaManzi kunye nodaka)
Le valve ayisiyo valve yesango yendabuko, kodwa isetyenziswa kakhulu kwiinqanawa apho izinto eziqinileyo okanye izinto ezinemicu zinokubonakala khona kwindawo ephakathi. Incakuba ebukhali inqumla ukungcola kwaye ithintele ukuvaleka.
Apho uyifumana khona:iiyunithi zokucoca amanzi amdaka, ukukhupha udaka, iinkqubo zamanzi amdaka.
7. Iivalvu zeSango loLwandle eziSebenzisiweyo (zoMbane okanye zoMoya)
Iinqanawa zanamhlanje zixhomekeke kakhulu kwi-automation. Iivalvu zesango ezisebenza zivumela ukusebenza kude ukusuka kwigumbi lolawulo lwenjini okanye kwinkqubo edibeneyo ye-automation yenqanawa.
Isetyenziselwa:ulawulo lwetanki ye-ballast, ukuvalwa kwengxakeko, ukuhanjiswa kwepetroli, ukuzenzekela kwe-injini kwigumbi.
8. Iivalvu zeSango eziValiweyo ngoXinzelelo
Ezi zenzelwe iinkqubo ezinoxinzelelo oluphezulu kakhulu okanye ezishushu kakhulu.
Izicelo eziqhelekileyo:imigca yomphunga, iinkqubo zebhoyila, iinkqubo zeoyile yobushushu.
