2. Amavalvu Ebhola Ancishisiwe
Incazelo: I-diameter yembobo incane kunepayipi, ikhawulela kancane ukugeleza koketshezi.
Sebenzisa: Ifanele imigqa engabalulekile lapho ukulahlekelwa kwengcindezi encane kwamukelekayo, njengamasistimu amanzi asizayo noma izintambo zokuthambisa.
Izinzuzo: Ibiza kakhulu futhi ihlangene uma iqhathaniswa namavalvu agcwele amanzi.
3. Amavalvu Ebhola Antantayo
Incazelo: Ibhola lintanta kancane lehla ngomfula ngaphansi kwengcindezi, licindezela esihlalweni ukuze lenze uphawu oluqinile.
Ukusetshenziswa: Okujwayelekile kumasistimu wokucindezela okuphansi kuya kokuphakathi njengemigqa kaphethiloli namasistimu we-bilge.
Izinzuzo: Idizayini elula, ukubekwa uphawu okuthembekile, nokunakekelwa okuphansi.
4. I-Trunnion Mounted Ball Valves
Incazelo: Ibhola liqiniswe phezulu nangaphansi, livimbela ukunyakaza ngaphansi kwengcindezi ephezulu.
Ukusetshenziswa: Kubalulekile ezinhlelweni zokusebenza ezinomfutho ophezulu njengokuvikela umlilo, ukuphatha impahla, nezintambo zikaphethiloli ezinkulu.
Izinzuzo: Amandla okuvala asezingeni eliphakeme kanye netorque encishisiwe yokusebenza, okuqinisekisa ukusebenza kwesikhathi eside.
5. I-V-Port Ball Valves
Incazelo: Ibhola linembobo emise okuka-“V”, evumela ukulawula ukugeleza okunembayo nokushoshozela.
Ukusetshenziswa: Kutholwe ezinhlelweni ezidinga ukulawulwa kokugeleza okunembile, njengamasistimu omjovo kaphethiloli kanye nokuthakwa kwamakhemikhali.
Izinzuzo: Inikeza ukulawula okukhulu kokugeleza koketshezi uma kuqhathaniswa namavalvu ebhola ajwayelekile.
6. Amavalvu ebhola ezindlela ezintathu kanye nanezindlela ezine
Incazelo: Lawa ma-valve anamachweba amaningi, avumela izinguquko zesiqondiso sokugeleza noma ukuphambukisa kwesistimu.
Sebenzisa: Kusetshenziswa ekucushweni kwamapayipi okuyinkimbinkimbi ukuze kudluliswe uphethiloli, ukulawula i-ballast, nokushintsha phakathi kwemigqa ehlukene yoketshezi.
Izinzuzo: Yehlisa isidingo samavalvu amaningi futhi yenza ukwakheka kwesistimu kube lula.
7. Insimbi Ehlezi Amavalvu Ebhola
Incazelo: Yakhelwe ngezihlalo zensimbi esikhundleni sezinto ezithambile, ezinikeza ukuqina okuphakeme.
Sebenzisa: Ifanele izinga lokushisa eliphezulu kanye nezicelo zoketshezi olunamanzi, njengemigqa yesitimu namasistimu e-exhaust.
Izinzuzo: Ukumelana nokugqokwa okuphezulu nempilo ende yesevisi.
8. I-Cryogenic Ball Valves
Incazelo: Iklanyelwe ukuphatha amazinga okushisa aphansi kakhulu, avame ukusetshenziswa ezinhlelweni zokubamba ze-LNG (igesi yemvelo ewuketshezi).
Sebenzisa: Ibalulekile kubathwali be-LNG yasolwandle kanye nokudluliswa kukaphethiloli we-cryogenic.
Izinzuzo: Igcina ukusebenza ngaphansi kwamazinga okushisa angaphansi kweziro ngaphandle kokuphazamisa ubuqotho bophawu.
9. Top Entry Ball Valves
Incazelo: Ivumela ukulungiswa nokulungiswa kusuka phezulu ngaphandle kokukhipha i-valve epayipini.
Ukusetshenziswa: Kusetshenziswa kumapayipi amakhulu nasezinhlelweni ezibucayi ezidinga ukuhlolwa njalo, njengezintambo ezinkulu zamanzi olwandle.
Izinzuzo: Inciphisa isikhathi sokuphumula futhi yenza ukulungiswa kube lula.
10. Ama-valve e-Fire-Safe Ball
Incazelo: Ifakwe izinto ezingashi eziqinisekisa ukuqhubeka nokusebenza ngezikhathi eziphuthumayo zomlilo.
Ukusetshenziswa: Kufakwe kumasistimu okucindezela umlilo kanye nokulawula uphethiloli.
Izinzuzo: Ithuthukisa ukuphepha kwemikhumbi kanye nokuthobela imithetho.
