Inani leamavalvuukufakwa emkhunjini kuncike ngobukhulu bomkhumbi, uhlobo, kanye nenhloso yawo—kodwa ezimweni eziningi, inani liphakeme kakhulu kunalokho abantu abakulindele. Umkhumbi omncane ogwini ungase ube namavalvu angu-200–500, kuyilapho imikhumbi emikhulu yasolwandle, izithwali ze-LNG, kanye nemikhumbi yasemanzini ivame ukuqukatha amavalvu angu-1,000–3,000 noma ngaphezulu. Ivalvu ngayinye idlala indima ebalulekile ekulawuleni, ekuhlukaniseni, noma ekulawuleni ukugeleza koketshezi namagesi kuzo zonke izinhlelo zemikhumbi yemikhumbi.
1. Kungani Imikhumbi Inamavalvu Amaningi Kangaka
Imikhumbi yasolwandle empeleni iyimizi entantayo kanye nezitshalo zezimboni ezihlanganisiwe, ezinezinhlelo eziningi okumele zisebenze ngokwethembeka ngaphansi kwezimo zolwandle eziyinselele. Uhlelo ngalunye—kungakhathaliseki ukuthi lulokuqhutshwa, ukuphepha, noma ukuphathwa kwempahla—ludinga inethiwekhi yalo yamavalvu ukuqinisekisa ukusebenza okuphephile nokusebenza kahle.
2. Izinhlelo Eziyinhloko Ezisebenzisa Ama-Valve Emikhumbini
-
①Izinhlelo Zamanzi Eziyi-Ballast – Sebenzisa ama-valve esango, ama-valve e-butterfly, bese uhlola ama-valve ukuze udlulisele amanzi ngaphakathi nangaphandle kwama-ballast tanks, ugcine ukuqina kwemikhumbi kanye nokusikwa kwayo.
-
②Igumbi Lenjini Nezinhlelo Zokusheshisa – Faka ama-valve embulunga, ama-valve okusiza ukuphepha, nama-valve okunciphisa ingcindezi ukuze uphathe amanzi okupholisa, uwoyela wokugcoba, umusi, kanye nokugeleza kukaphethiloli.
-
③Izinhlelo Zokuphatha Impahla – Kuma-tanker kawoyela, izithwali ze-LNG, kanye nezithwali zamakhemikhali, ama-valve asebenza kahle alawula ukulayisha, ukudlulisa, kanye nokukhipha impahla ngaphansi kwemithetho eqinile yokuphepha.
-
④Izinhlelo Zokucisha Umlilo – Zihlonyiswe ngama-valve okuvala ngokushesha, ama-valve okudonsa amanzi, kanye nama-valve okulawula ingcindezi ukuqinisekisa impendulo esheshayo yesimo esiphuthumayo noma kuphi lapho ugibele khona.
-
⑤Izinhlelo ze-HVAC kanye namanzi ahlanzekile – Sebenzisa ama-valve okulawula, ama-valve okulawula angacindezeli (ama-PICV), kanye nama-valve okulinganisela ukulawula izinga lokushisa, ingcindezi, kanye nokugeleza ezindaweni zokuhlala.
-
⑥Izinhlelo Zamanzi Angcolile Nezibiyeli – Sebenzisa amavalvu angabuyisi, amavalvu esango lommese, namavalvu e-diaphragm ukuze uphathe indle, amanzi ampunga, kanye nokukhishwa kwebiyeli ngokuphephile.
3. Ukubaluleka Kwekhwalithi Nokunakekelwa Kwevalvu
Ngenxa yokuthi ama-valve asolwandle asebenza endaweni enosawoti omningi, enomswakama omningi, ukumelana nokugqwala nokuqina kubalulekile. Abanikazi bemikhumbi bavame ukukhetha izinto ezisezingeni lolwandle njengethusi, insimbi engagqwali, noma insimbi ehlanganisiwe eboshwe ngokukhethekile. Ukuhlolwa njalo kwama-valve, ukuhlolwa kwe-hydrostatic, kanye nokugcinwa kwawo kubalulekile ukuze kugwenywe ukuvuza, ukulahleka kwengcindezi, kanye nezingozi zokuphepha ezingaba khona olwandle.
