- Nqe lus piav qhia: Ib qho flange li qub siv cov khoom siv tsawg dua ob lub flange lossis lub valve, uas txo cov nqi tsim khoom thiab tseem txo cov nqi tsheb thauj mus los. Nws yog bolted rau cov yeeb nkab flange thiab clamped nyob rau hauv qhov chaw.
4. Npauj npaim valve
- Txoj kab uas hla: DN50-DN 600 Nws
- Nqe lus piav qhia: Lug npauj npaim li qub (Lug hom) yog qhov tsim nyog rau cov tshuab ntawm qhov kawg ntawm cov kav dej lossis qhov uas yuav tsum tau ua kom nquag plias. Txoj kab uas hla yog me me thiab nruab nrab. Vim muaj kev txwv cov qauv, kev siv txoj kab uas hla loj yog tsawg dua.
5. U-hom npauj npaim valve
- Calibre ntau yam: DN100-DN1800 Nws
- Cov lus piav qhia: U-hom npauj npaim li qub feem ntau yog siv rau cov kav dej loj, xws li cov kav dej hauv nroog, kev kho dej phwj tuaj, thiab lwm yam, thiab cov qauv tsim nyog rau cov dej ntws siab thiab tsis tshua muaj siab sib txawv scenarios.
| Kev piav qhia | Common Size Range (DN) | Ntsiab Lus |
|---|---|---|
| Npauj Npaim Valve | DN15-DN600 | Compact qauv, nqi-zoo, dav siv nyob rau hauv qis-rau nruab nrab-siab tshuab; qhov loj dua rau cov kev pabcuam tsis tseem ceeb. |
| Npauj Npaim Valve | DN50-DN600 | Haum rau cov kev pabcuam tuag-kawg thiab cov tshuab uas xav tau disassembly ntawm ib sab. Kev tuav tswj me ntsis zoo dua li hom dej. |
| Ib-Flanged Npauj Npaim Valve | DN700-DN1000 | Feem ntau nyob rau hauv faus los yog tsis muaj zog tshuab; lighter hnyav thiab yooj yim rau nruab. |
| Ob-Flanged Npauj Npaim Valve | DN50-DN3000 (txog DN4000 hauv qee kis) | Haum rau high-pressure, loj-inch, thiab tseem ceeb heev daim ntaub ntawv; zoo sealing kev ua tau zoo. |
| U-hom npauj npaim Valve | DN50-DN1800 | Feem ntau cov roj hmab-lined lossis tag nrho-lined rau corrosion kuj hauv cov kev pabcuam tshuaj. |

2. Calibre ntau yam ntawm npauj npaim li qub cais los ntawm cov yam ntxwv hom
1. Centerline npauj npaim valve
- Calibre ntau yam: DN50-DN1200 Nws
- Nqe lus piav qhia: Centerline npauj npaim valve (mos foob lossis elastic foob) muaj cov qauv yooj yim, haum rau cov xov xwm tsis tshua muaj siab thiab kub ib txwm, nruab nrab caliber ntau yam, thiab dav siv hauv dej, roj thiab lwm yam.
2. Ob chav eccentric npauj npaim valve
- Calibre ntau yam: DN50-DN1800 Nws
- Nqe lus piav qhia: Ob chav eccentric npauj npaim valve txo cov foob hnav los ntawm kev tsim eccentric, haum rau cov tshuab tsis tshua muaj siab thiab nruab nrab, muaj qhov dav dav, thiab feem ntau siv hauv cov roj thiab roj, tshuaj thiab lwm yam lag luam.
3. Triple eccentric npauj npaim valve
- Calibre ntau yam: DN100-DN3000
- Nqe lus piav qhia: Triple eccentric npauj npaim valve (nyuaj foob) yog tsim rau kub, siab siab thiab hnyav ua haujlwm. Nws muaj ntau yam caliber thiab feem ntau siv rau hauv cov kav dej loj, xws li fais fab, petrochemical, thiab lwm yam.
