Raws li cov chaw tsim khoom lag luam zoo tshaj plaws, ZFA feem ntau tau txais cov lus nug txog qhov sib txawv ntawm ntau hom valve. Ib lo lus nug ntau yog: Qhov txawv ntawm anpauj npaim valvethiab anpauj npaim check valve? Thaum lawv sib koom cov npe zoo sib xws thiab ob qho tib si siv cov qauv tsim disc, lawv cov haujlwm, kev ua haujlwm, thiab cov ntawv thov sib txawv heev.
Cov lus qhia no qhia txog qhov sib txawv tseem ceeb no, kos rau ZFA qhov kev txawj ntse. Peb yuav hais txog cov hauv paus ntsiab lus-xws li txhais, tsim qauv, thiab cov qauv kev ua haujlwm. Txawm hais tias koj yog ib tus kws tshaj lij, tus kws tshaj lij kev muag khoom, lossis tus kws tshaj lij kev lag luam, tsab xov xwm no yuav pab koj txiav txim siab.
1. Npauj Npaim Valve yog dab tsi?
Npauj npaim valve yog lub quarter-tig teb valve feem ntau siv rau kev khiav dej num lossis kev sib cais hauv cov kav dej. Nws nta lub disc uas tig ntawm lub hauv paus axis kom qhib lossis kaw txoj kev ntws.
1.1 Npauj Npaim Valve ua haujlwm li cas
Lub valve ua haujlwm los ntawm kev tig lub disc 90 degrees: qhib tag nrho, tso cai rau tsis muaj kev cuam tshuam, lossis kaw, thaiv txoj kev ntws. Ib nrab kev sib hloov tso cai rau throttling, ua rau nws haum rau regulating ntws.
1.2 Cov Ntawv Thov Kev Sib Tham
- Cov nroj tsuag kho dej
- HVAC Systems
- Kev ua tshuaj lom neeg
- Kev lag luam zaub mov thiab dej haus
2. Npauj Npaim Check Valve yog dab tsi?
Npauj npaim check valve, tseem hu ua ob-disc check valve, yog ib qho tsis rov qab los yog ib txoj kev valve uas tiv thaiv kev rov qab hauv cov kav dej. Tsis zoo li npauj npaim li qub, nws ua haujlwm tsis muaj kev cuam tshuam sab nraud.
2.1 Txoj Cai Ua Haujlwm
Forward flow pushes lub disc qhib, kov yeej lub caij nplooj ntoos hlav nro. Thaum ntws nres los yog thim rov qab, lub caij nplooj ntoos hlav kaw sai sai, tsim kom muaj lub foob kom tsis txhob rov qab los. Qhov kev ua haujlwm tsis siv neeg no yuav tsum tsis muaj kev cuam tshuam tib neeg.
2.2 Cov Ntawv Thov Kev Sib Tham
- Pump Discharge Lines
- Compressor Systems
- Marine thiab Offshore Platforms
- Kev tswj dej khib nyiab
3. Qhov txawv ntawm Npauj Npaim Valve thiab Npauj Npaim Kos Valve
Thaum ob qho tib si siv lub tshuab disc, lawv cov ntawv thov tseem ceeb yog qhov sib txawv. Nov yog qhov sib piv ntawm ib sab:
| Yam | Npauj Npaim Valve | Npauj Npaim Check Valve |
| Lub luag haujlwm tseem ceeb | Flow regulation thiab cais tawm | Kev tiv thaiv rov qab |
| Kev ua haujlwm | Manual los yog actuated rotation | Automatic (lub caij nplooj ntoos hlav-loaded) |
| Disc Design | Ib qho disc ntawm ncej | Dual phaj nrog hinges thiab springs |
| Flow Direction | Bidirectional (nrog sealing zoo) | Unidirectional nkaus xwb |
| Kev teeb tsa | Wafer, lug, los yog flanged | Wafer, lug, los yog flanged |
Cov lus no qhia txog cov laj thawj ntawm kev xaiv ib qho ntawm lwm qhov: npauj npaim li qub rau kev tswj, kos li qub rau kev tiv thaiv.
6. Dej rauj thiab teb ceev
Dej rauj feem ntau tshwm sim thaum cov kua dej ntws tawm sai sai, xws li thaum lub valve kaw sai lossis lub twj tso kua mis kaw dheev. Qhov no ua rau lub zog kinetic hloov mus rau hauv lub zog nthwv dej uas nthuav tawm raws cov yeeb nkab. Qhov kev poob siab no tuaj yeem ua rau cov yeeb nkab tawg, flange loosening, lossis valve puas. Npauj npaim li qub thiab npauj npaim kos li qub sib txawv hauv lawv lub peev xwm los tuav dej rauj vim lawv cov qauv tsim thiab kev ua haujlwm.
6.1 Npauj Npaim li qub thiab dej rauj
Qhov ceev ntawm lub npauj npaim valve kaw nyob ntawm nws txoj kev ua haujlwm (phau ntawv, pneumatic, lossis hluav taws xob). Kev kaw nrawm tuaj yeem ua rau dej rauj, tshwj xeeb tshaj yog nyob rau hauv cov kab ke uas muaj tus nqi ntws los yog siab siab. Qhov no yuav tsum tau saib xyuas tshwj xeeb hauv cov twj tso kua mis.
Npauj npaim li qub tsis yog tsim los tiv thaiv kev rov qab los. Yog hais tias muaj kev pheej hmoo ntawm backflow nyob rau hauv lub system, dej rauj yuav exacerbated los ntawm backflow.
6.2 Npauj Npaim Check Valves thiab Dej Rauj
Npauj Npaim kos li qub (ob-disc kos li qub) tau kaw siv lub caij nplooj ntoos hlav-loaded ob lub discs kom tsis txhob rov qab. Lawv tau tsim los teb sai sai rau cov kev hloov pauv hauv kev khiav dej num thiab xyuas kom muaj kev kaw sai sai thaum cov dej nres lossis thim rov qab, tiv thaiv lub kaw lus los ntawm kev puas tsuaj rov qab. Txawm li cas los xij, qhov kev kaw nrawm no tuaj yeem ua rau dej rauj.
7. FAQ
Kuv yuav ua li cas thiaj paub qhov txawv ntawm npauj npaim valve thiab daim tshev valve?
Npauj npaim li qub muaj cov actuators, thaum cov tshev valve tsis ua.
Cov npauj npaim valve puas tuaj yeem siv los ua qhov kos valve?
Tsis yog, vim nws tsis muaj qhov tsis siv neeg kaw tshuab. Qhov thim rov qab kuj muaj tseeb.
Cov valve no xav tau kev saib xyuas dab tsi?
Npauj npaim li qubyuav tsum tau kuaj lub rooj zaum;check li qubyuav tsum tau kuaj xyuas lub caij nplooj ntoos hlav txhua 6-12 lub hlis.
