Dab tsi yog NRS Rooj Vag Valve
NRS (Qia Tsis Nce)lub qhov rooj vagmuaj ib lub qia uas tig rau hauv qhov chaw thaum ua haujlwm - lub qia tsis txav mus rau saum lossis nqis sab nraud thaum lub valve qhib lossis kaw.
Cov Nta Tseem Ceeb:
- ①Tuscov xov ntawm lub qia yog nyob rau hauv lub cev valve, nyob rau hauv kev sib cuag nrog cov kua dej.
- ② Kev tsim qauv me me—zoo tagnrho rauqhov chaw nqaimlos yog kev teeb tsa hauv av.
- ③Feem ntau siv rau hauvcov kab ke dej hauv nroog, kev ywg dej, thiab cov kav dej tua hluav taws.
Tej yam yuav tsum xav txog:
- ①Tusqhov chaw ntawm lub valve tsis pomsab nraud—koj yuav tsum vam khom lub cim qhia qhov chaw lossis lub cim xeeb.
- ② Vim tias lub qia raug rau cov xov xwm hauv lub valve,xebtuaj yeem dhau los ua teeb meem txij nkawm hauv qee qhov chaw.
Lub Rooj Vag OS&Y yog dab tsi?
Cov qhov rooj vag OS&Y (Sab Nraud Ntsia Hlau thiab Yoke) muaj lub qia uas nce thiab nqis pom tseeb thaum lub log tes tig. Cov xov nyob sab nraud lub cev valve, cais tawm ntawm cov kua.
Cov Nta Tseem Ceeb:
- ①Tusqhov chaw ntawm lub valve yooj yim pom- yog tias lub qia nyob rau sab saud, lub valve qhib; yog tias nyob rau hauv qab, nws kaw lawm.
- ② Lub qia yog tiv thaiv los ntawm cov xov xwm, txo qhov muaj feem ntawm kev xeb.
- ③Yuav tsum tau muaj ntau tus neegcov qauv kev tiv thaiv hluav taws(NFPA) rau cov tshuab txau dej tua hluav taws.
Tej yam yuav tsum xav txog:
- ①Yuav tsum muaj chaw ntsug ntxiv kom haum rau cov qia nce.
- ②Feem ntau sivsaum av, nyob rau hauv cov chav kho tshuab, lossis qhov twg xav tau kev txheeb xyuas pom.
NRS VS OS&Y: Kev Sib Piv Ib Sab
| Feature | NRS Rooj Vag Valve | OS&Y Rooj Vag Valve |
|---|---|---|
| Kev Txav Mus Los Ntawm Qia | Sab hauv, tsis nce | Sab nraud, qia nce thaum lub valve qhib |
| Qhov Qhia Txog Qhov Muag Pom | No | Yog |
| Qhov Chaw Xav Tau | Compact, zoo dua rau hauv av | Yuav tsum tau qhov chaw ntsug |
| Kev Tiv Thaiv Kev Xeb | Muaj kev phom sij dua (cov kua dej sib cuag ntawm cov qia) | Kev tiv thaiv zoo dua (cais tawm ntawm qia) |
| Cov Ntaub Ntawv Siv Zoo Tshaj Plaws | Cov kav dej hauv av, cov kav dej | Cov tshuab txau dej tua hluav taws, chav kho tshuab |
| Kev Siv Tiv Thaiv Hluav Taws | Tsis pom zoo los ntawm NFPA rau cov tshuab tua hluav taws | NFPA-tus qauv nyiam rau cov tshuab tua hluav taws |
| Kev Txij Nkawm | Nyuaj me ntsis rau kev tshuaj xyuas lossis kho | Yooj yim dua los tshuaj xyuas thiab tswj xyuas |
Qhov twg OS&Y thiab NRS Valves siv ntau
NRS Rooj Vag Valves
- ①Cov kav dej hauv av
- ② Kev rho tawm Hydrant
- ③Cov txheej txheem dej
- ④Cov txheej txheem kev lag luam uas muaj qhov chaw txwv
OS&Y Rooj Vag Valves
- ①Cov tshuab txau dej tua hluav taws (NFPA-ua raws li)
- ② Chav cav Marine
- ③Cov chaw ua roj thiab cov chaw tsim tshuaj lom neeg
- ④Cov chaw kho dej
Vim Li Cas Nws Tseem Ceeb Hauv Cov Ntawv Thov Marine thiab Hluav Taws
- ①Hauv kev tiv thaiv hluav taws, kev pom tseeb yog qhov tseem ceeb - OS&Y li qub yog qhov zoo dua.
- ② Hauv cov kab ke hauv dej hiav txwv, qhov chaw tsawg thiab cov xwm txheej tsis zoo, NRS li qub yuav tsim nyog dua, tab sis xav tau cov ntaub ntawv tiv taus corrosion.
