3. Ib lub flange npauj npaim valve
- Txoj kab uas hla: DN700–DN1000
- Kev Piav Qhia: Cov twj tso kua dej ib leeg siv cov khoom siv tsawg dua li cov twj tso kua dej ob chav flange lossis lug, uas txo cov nqi tsim khoom thiab tseem txo cov nqi thauj mus los. Nws tau bolted rau ntawm cov yeeb nkab flange thiab clamped rau hauv qhov chaw.
4. Lub pob valve npauj npaim
- Txoj kab uas hla: DN50–DN600
- Kev Piav Qhia: Cov li qub npauj npaim Lug (Hom Lug) yog qhov tsim nyog rau cov kab ke ntawm qhov kawg ntawm cov kav dej lossis uas xav tau kev rhuav tshem ntau zaus. Qhov ntau thiab tsawg ntawm txoj kab uas hla yog me thiab nruab nrab. Vim muaj kev txwv ntawm cov qauv, kev siv txoj kab uas hla loj tsis tshua muaj.
5. U-hom npauj npaim valve
- Caliber ntau yam: DN100–DN1800
- Kev piav qhia: U-hom npauj npaim li qub feem ntau yog siv rau cov kav dej loj, xws li kev muab dej hauv nroog, kev kho dej phwj tuaj, thiab lwm yam, thiab cov qauv no tsim nyog rau cov dej ntws siab thiab qhov sib txawv ntawm qhov siab qis.
| Kev piav qhia | Qhov Loj Sib Xws (DN) | Cov Lus Qhia Tseem Ceeb |
|---|---|---|
| Dej Npauj Npaim Valve | DN15-DN600 | Cov qauv compact, tus nqi tsim nyog, siv dav hauv cov kab ke qis-rau nruab nrab-siab; qhov loj dua rau cov kev pabcuam tsis tseem ceeb. |
| Lug Npauj Npaim Valve | DN50-DN600 | Haum rau kev pabcuam tsis muaj qhov kawg thiab cov kab ke uas yuav tsum tau muab rhuav tawm ntawm ib sab. Kev tswj hwm siab zoo dua me ntsis dua li hom dej. |
| Ib-Flanged Npauj Npaim Valve | DN700-DN1000 | Feem ntau nyob rau hauv cov kab ke faus lossis qis-siab; sib dua qhov hnyav thiab yooj yim rau nruab. |
| Ob Chav-Flanged Npauj Npaim Valve | DN50-DN3000 (txog li DN4000 qee zaum) | Haum rau kev siv siab, txoj kab uas hla loj, thiab cov ntawv thov tseem ceeb; kev ua tau zoo heev ntawm kev sib khi. |
| U-hom npauj npaim Valve | DN50-DN1800 | Feem ntau yog roj hmab-lined lossis tag nrho-lined rau kev tiv thaiv xeb hauv kev pabcuam tshuaj lom neeg. |

2. Qhov ntau thiab tsawg ntawm cov npauj npaim li qub raug faib ua pawg raws li hom qauv
1. Lub qhov dej npauj npaim nruab nrab
- Caliber ntau yam: DN50–DN1200
- Kev piav qhia: Centerline npauj npaim valve (lub foob mos lossis lub foob elastic) muaj cov qauv yooj yim, haum rau cov xov xwm kub qis thiab kub ib txwm, qhov nruab nrab caliber, thiab siv dav hauv dej, roj thiab lwm yam kab ke.
2. Ob chav eccentric npauj npaim valve
- Caliber ntau yam: DN50–DN1800
- Kev piav qhia: Ob chav eccentric npauj npaim valve txo qhov hnav ntawm lub foob los ntawm kev tsim eccentric, tsim nyog rau cov kab ke siab qis thiab nruab nrab, muaj ntau yam caliber, thiab feem ntau siv hauv roj thiab roj av, tshuaj lom neeg thiab lwm yam lag luam.
3. Peb lub qhov rooj npauj npaim eccentric
- Caliber ntau yam: DN100–DN3000
