Uma kukhulunywa ngokukhetha ama-valve afanele izinhlelo zasolwandle, ukukhetha kungaba nzima—ikakhulukazi uma izifinyezo ezifanaI-SNRfuthiI-SDNRLezi zinhlobo ezimbili ze-amavalvu embulunga angabuyizisetshenziswa kabanzi ezinhlelweni zamapayipi olwandle, kodwa zisebenza imisebenzi ehlukene kancane. Ukuqonda umehluko wazo kubalulekile ukuqinisekisa ukusebenza kwemikhumbi okuthembekile nokuphumelelayo.Kulesi sihloko, sizohlolaumehluko phakathi kwama-valve e-SNR kanye ne-SDNR, indlela ezisebenza ngayo, nokuthi zivame ukusetshenziswa kuphi ezinhlelweni zobunjiniyela basolwandle.
Ukuqonda Ama-SNR Valves (Ama-Stop Non-Return Valves)
I-SNR, okufushane ngokuthiYeka Ukungabuyi, kubhekisela ohlotsheni lweivalvu yokuhlolaYakhelwe ukuvumela uketshezi ukuthi lugeleze ohlangothini olulodwa kuphela. Lawa ma-valve avuleka ngokuzenzakalelayo lapho ingcindezi epayipini idlula ingcindezi yokuqhekeka futhi ayavaleka lapho ukugeleza kubuyela emuva, okuvimbela ukugeleza emuva. Afaneleka kakhulu lapho kudingeka ukugeleza okuqondile ngaphandle kwesidingo sokungenelela komuntu.
Izici Eziyinhloko Zama-SNR Valve
- ☆ Ukusebenza okuzenzakalelayo okusekelwe ekuqondeni kokugeleza
- ☆ Ayikho indlela yokulawula ngesandla
- ☆ Yakhelwe ukuvimbela ukugeleza okuphambene nokuvikela imishini
- ☆ Ivame ukusetshenziswa emigqeni yokubuyisela amanzi apholile, izinhlelo ze-ballast, kanye nemigqa ye-condensate
Ukuqonda Amavalvu e-SDNR (Amavalvu Okuma kanye Nawo Angabuyi)
I-SDNR, okufushane ngokuthiUkuma Nokungabuyi, ihlanganisa imisebenzi emibili ku-valve eyodwa:ivalvu yokuhlolafuthiivalvu yomhlabaLokhu kusho ukuthi akugcini nje ngokuvumela uketshezi ukuthi lugeleze ohlangothini olulodwa futhi kuvimbele ukugeleza okuphambene, kodwa futhi kungavalwa ngesandla ukuze kumiswe ukugeleza ngokuphelele.Banikeza ukulawula nokuphepha okwengeziwe, ikakhulukazi ezimweni eziphuthumayo lapho ukuhlukaniswa komugqa kubaluleke kakhulu.
Izici Eziyinhloko Zama-Valve e-SDNR
- ☆Isebenza njengevalvu yokuhlola kanye nevalvu yokuma
- ☆Ukusebenza ngesandla ukuvala isondo lesandla noma i-actuator
- ☆ Kusetshenziswa ezinhlelweni ezidinga kokubili ukulawula ukugeleza kanye nokusebenza okungabuyi
- ☆Isetshenziswa njalo emigqeni kaphethiloli, ezinhlelweni zokugcoba, kanye nezinhlelo zokuvikela umlilo
I-SNR vs SDNR
| Isici | I-SNR Valve | I-Valve ye-SDNR |
| Isiqondiso Sokugeleza | Indlela eyodwa (ukungabuyi) | Indlela eyodwa (ukungabuyi) |
| Ukuvala Ngokuzenzela | Akunakwenzeka | Ukuvalwa ngesandla nge-handwheel |
| Uhlobo Lokusebenza | Okuzenzakalelayo ngokugcwele | Manual + othomathikhi |
| Amacala Okusetshenziswa Okuvamile | Ukulawula ukugeleza okungabalulekile, imigqa yokupholisa | Izinhlelo ezibalulekile zokuphepha, uwoyela kaphethiloli, i-ballast |
| Isicelo eMarine | Ukuvikelwa kokugeleza kuphela | Ukuvikelwa kokugeleza + ukulawula ngesandla |
Sebenzisana Nomkhiqizi We-Marine Valve Onolwazi
At I-Qingdao I-Flow, sigxile ekuhlinzekeni ngekhwalithi ephezuluamavalvu olwandlekufaka phakathiI-SNRfuthiAmavalvu embulunga ye-SDNR, eyenzelwe ukusebenza ezindaweni ezidinga kakhulu olwandle. Njengoba uneminyaka engaphezu kwengu-10 yesipiliyoni, izitifiketi ezifana ne-CE, i-DNV, ne-ABS, kanye namakhasimende emazweni angaphezu kuka-40, sikusiza ukuqinisekisa ukuphepha, ukusebenza, kanye nokuthobela imithetho olwandle.
