Amavalvu ayizingxenye ezibalulekile ezinhlelweni zamapayipi ebhodi lomkhumbi, adlala indima ebalulekile ekulawuleni ukugeleza, ingcindezi, kanye nesiqondiso soketshezi kuwo wonke umkhumbi. Basiza ekuqinisekiseni ukuthi amasistimu ahlukahlukene, okuhlanganisa ukupholisa, i-ballast, uphethiloli, nokucisha umlilo, asebenza kahle, ngokuphepha nangokuthembekile. Ngaphandle kokulawula amavalvu ngendlela efanele, amasistimu oketshezi emkhunjini angaba sengozini yokungasebenzi kahle, ukuvuza, nezinye izingozi zokuphepha. Nakhu ukuhlukaniswa kokuthi ama-valve anikela kanjani ekulawuleni umfutho wokugeleza nokuqondiswa koketshezi kumasistimu amapayipi ebhodi lomkhumbi
1. Ukulawulwa Kokugeleza Nokulawula
- Amavalvu Ebhola: Asetshenziselwa ukulawula okulula kokuvula/ukuvala, lawa mavalvu avumela noma amise ukugeleza koketshezi ohlelweni ngokuvula noma ukuvala ngokugcwele. Zibalulekile ekuhlukaniseni amasistimu okunakekelwa noma ezimeni eziphuthumayo.
- Ama-Globe Valves: Lawa aklanyelwe ukuvumela ukugobhoza okunembile kokugeleza koketshezi. Avame ukusetshenziswa ezinhlelweni lapho isilawuli sokugeleza sidinga ukulungiswa njalo, njengamasistimu okupholisa noma izintambo zikaphethiloli.
2. Ukulawula Ingcindezi
- Amavalufu Okusiza: Lawa mavalvu avuleka ngokuzenzakalelayo ukuze akhulule ukucindezela lapho kweqa umkhawulo omisiwe. Uma kwenzeka kuba nomfutho owedlulele, njengakusistimu kaphethiloli noma imigqa ye-hydraulic, i-valve yokukhulula ivimbela umonakalo oyinhlekelele ngokukhipha ngokuphepha ukucindezela okukhulu.
- Amavalufu Alawula Ingcindezi: Lawa asetshenziselwa ukugcina ukucindezela okungaguquki phakathi kwebanga elithile, okubalulekile kumasistimu adinga ukucindezela okuzinzile ukuze asebenze ngendlela efanele, njengesistimu yokupholisa yenjini noma isistimu yokulethwa kukaphethiloli.
3. Ukulawula Ukugeleza Okuqondile
- Hlola Amavaluvu: Lawa avimbela ukugeleza emuva ngokuqinisekisa ukuthi uketshezi lungageleza ohlangothini olulodwa kuphela. Zibalulekile ekuvimbeleni ukugeleza okubuyela emuva okungalimaza amathuluzi noma kuphazamise ukusebenza kwesistimu. Isibonelo, ezinhlelweni ze-bilge noma izinhlelo ze-ballast, ama-valve okuhlola avimbela amanzi olwandle ukuthi ageleze abuyele emkhunjini.
- Amavalvu Ezindlela Ezintathu Nanezindlela Eziningi: Lawa mavalvu aklanyelwe ukuqondisa kabusha ukugeleza koketshezi emigudwini ehlukene. Isibonelo, zingasetshenziswa ukushintsha phakathi kwezintambo zikaphethiloli ezihlukene noma ukuphambukisa amanzi okupholisa ezingxenyeni ezihlukahlukene zenjini.
4. Ukuzihlukanisa kanye Nokuvala
- Amavalvu Esango: Lawa ajwayele ukusetshenziselwa izinjongo zokuvala ngokugcwele, lapho kudingeka khona ukuyeka ngokuphelele ukugeleza koketshezi. Ezimweni eziphuthumayo noma ngesikhathi sokunakekelwa, ama-valve esango avumela ukuhlukaniswa kwezingxenye zesistimu yamapayipi omkhumbi.
- Amavalvu Ovemvane: Ngokuvamile asetshenziselwa ukulawula umthamo omkhulu wokugeleza, amavalvu ovemvane nawo asetshenziselwa ukuvala ngokushesha izicelo. Idizayini yabo ehlangene ivumela ukusebenza ngokushesha nokubeka uphawu ngempumelelo.
5. Ukuphepha Ezimeni Eziphuthumayo
- I-Fire Suppression Systems: Amavalvu alawula ukugeleza kwamanzi noma amakhemikhali abamba umlilo ukuze acindeze amalangabi uma kuba nomlilo. Ukusebenza ngokushesha nangokuthembekile kwalawa ma-valve kubalulekile ekudambiseni izingozi.
- Amavalvu Okuvala Izimo Eziphuthumayo: Lawa mavalvu aklanyelwe ukuvala ngokushesha amasistimu abucayi, njengezintambo zikaphethiloli noma imishini, esimweni esiphuthumayo, ukuvimbela umonakalo owengeziwe noma ingozi.
6. Ukulawula Ukugeleza Kwezinhlelo Ezikhethekile
- I-Ballast Systems: Amavalvu alawula ukugeleza kwamanzi olwandle ukungena nokuphuma emathangeni e-ballast, esiza umkhumbi ugcine uzinzo kanye nokusatshalaliswa kwesisindo esifanele. Lokhu kubalulekile ebhalansini yomkhumbi, ikakhulukazi phakathi nokulayisha noma ukuthulula.
- Amasistimu Okupholisa: Amavalvu alawula ukugeleza kwamanzi ngamasistimu okupholisa omkhumbi ukuze aqinisekise ukuthi izinjini neminye imishini ihlala ngaphakathi kwamazinga okushisa okusebenza aphephile.
- Amasistimu Kaphethiloli: Kuhlelo lokulethwa kukaphethiloli, amavalvu alawula ukuhamba kukaphethiloli ukusuka emathangeni okugcina ukuya ezinjinini, okuqinisekisa ukuthi uphethiloli unikezwa ngengcindezi efanele nangesilinganiso esifanele.
