Iyini i-NRS Gate Valve
I-NRS (Isiqu Esingavuki)amavalvu esangoinesiqu esijikeleza endaweni yaso lapho sisebenza—isiqu asihambi phezulu noma phansi ngaphandle njengoba ivalvu ivulwa noma ivaliwe.
Izici Eziyinhloko:
- ①Iimicu yesiqu ingaphakathi komzimba wevalvu, uma ithinta uketshezi.
- ②Umklamo omncane—ulungeleizindawo ezixineneyonoma ukufakwa ngaphansi komhlaba.
- ③Ivame ukusetshenziswa ku-izinhlelo zamanzi zikamasipala, ukuchelela, kanye nemigqa yamanzi omlilo.
Okucatshangelwayo:
- ①Iindawo yevalvu ayibonakalingaphandle—kumele uthembele enkombeni yesikhundla noma kwimemori.
- ②Njengoba isiqu sivezwa yimidiya engaphakathi kwevalvu,ukugqwalakungaba yinkinga yokulungisa ezindaweni ezithile.
Iyini i-OS&Y Gate Valve
Amavalvu esango le-OS&Y (Outside Screw and Yoke) anesiqu esiphakama futhi sehle ngokubonakalayo njengoba isondo lesandla liphendulwa. Izintambo zingaphandle komzimba wevalvu, zihlukaniswe noketshezi.
Izici Eziyinhloko:
- ①Iindawo yevalvu kulula ukuyibona—uma isiqu siphezulu, ivalvu ivulekile; uma iphansi, ivaliwe.
- ②Isiqu sivikelwe ezintweni ezithinta imidiya, okunciphisa amathuba okugqwala.
- ③Kudingwa ngabaningiamazinga okuvikela umlilo(NFPA) yezinhlelo zokufafaza umlilo.
Okucatshangelwayo:
- ①Kudinga isikhala esithe xaxa ukuze kuhlangatshezwane nesiqu esikhuphukayo.
- ②Ivame ukusetshenziswangaphezu komhlabathi, emakamelweni omshini, noma lapho kudingeka khona ukuqinisekiswa okubonakalayo.
I-NRS VS OS&Y: Ukuqhathanisa Okuseceleni
| Isici | I-Valve yeSango le-NRS | I-valve yesango le-OS&Y |
|---|---|---|
| Ukunyakaza Kwesiqu | Ngaphakathi, akuvuki | Ngaphandle, isiqu siyaphakama njengoba ivalvu ivuleka |
| Isikhombisi Sendawo Ebonakalayo | No | Yebo |
| Isidingo Sesikhala | Incane, ingcono ngaphansi komhlaba | Kudinga ukuvuleka okuqondile |
| Ukumelana Nokugqwala | Ukuthinteka kalula (uketshezi lokuxhumana kwesiqu) | Ukuvikelwa okungcono (isiqu sihlukanisiwe) |
| Ikesi Lokusetshenziswa Elifanele | Amapayipi amanzi angaphansi komhlaba, amapayipi amanzi | Izinhlelo zokufafaza umlilo, amakamelo omshini |
| Ukusetshenziswa Kokuvikela Umlilo | Akukhuthazwa yi-NFPA ngezinhlelo zomlilo | Izinga elikhethwa yi-NFPA lezinhlelo zomlilo |
| Ukulungiswa | Kunzima kancane ukuhlola noma ukulungisa | Kulula ukuhlola ngokubona nokunakekela |
Asetshenziswa Kanjani Ama-valve e-OS&Y kanye ne-NRS?
Amavalvu Esango Le-NRS
- ①Amapayipi amanzi angaphansi komhlaba
- ②Ukuhlukaniswa kwamanzi
- ③Izinhlelo zokunisela
- ④Izinhlelo zezimboni ezinesikhala esincane
Amavalvu Esango le-OS&Y
- ①Izinhlelo zokufafaza umlilo (ezihambisana ne-NFPA)
- ②Amakamelo enjini yolwandle
- ③Izindawo zokuhlanza kanye nezitshalo zamakhemikhali
- ④Izindawo zokuhlanza amanzi
Kungani Kubalulekile Ezicelweni Zokusebenza Zasolwandle Nomlilo
- ①Ekuvikeleni umlilo, ukuqinisekiswa okubonakalayo kubalulekile—ama-valve e-OS&Y ayathandwa.
- ②Ezinhlelweni zasolwandle, lapho isikhala silinganiselwe khona futhi izimo zinzima, ama-valve e-NRS angase afaneleke kakhulu, kodwa adinga izinto ezingagqwali.
