Cov Khoom Siv thiab Cov Kev Qhia Tshwj Xeeb rau 400mm Npauj Npaim Valve
Lub cev valve feem ntau yog siv cov hlau los yog cov pa roj carbon steel, nrog cov hlau tsis muaj steel (xws li, SS304/316) muaj rau qhov chaw corrosive. Lub disc feem ntau yog carbon steel clad nrog stainless hlau los yog ua los ntawm stainless hlau tag nrho kom ntseeg tau lub zog thiab corrosion kuj. Cov khoom siv lub rooj zaum raug xaiv raws li qhov yuav tsum tau muaj kev sib khi: EPDM yog tsim rau cov xov xwm dej, PTFE tuaj yeem siv rau ntau yam tshuaj, thiab cov rooj zaum hlau tawv tuaj yeem tiv taus qhov kub thiab txias.
Kev sib txuas, kev ua haujlwm, thiab kev tsim qauv siab
Lub valve no feem ntau muaj wafer, flanged, los yog lugged kev sib txuas kom haum rau cov kev xav tau ntawm cov kav dej sib txawv. Tus txheej txheem actuation yog hloov tau, tso cai rau kev siv phau ntawv nrog lub zog lossis lub gearbox, lossis kev sib txuas rau pneumatic lossis hluav taws xob actuators rau kev tswj tsis siv neeg. Nws cov kev ntsuas nominal siab yog PN10 lossis PN16 (suav nrog Chav Kawm 150), ua tau raws li qhov xav tau ntawm cov kav dej feem ntau.
Nta thiab daim ntawv thov scenarios ntawm 400mm Npauj Npaim Valve
Lub valve ua kom ceev qhib / kaw ua haujlwm los ntawm 90-degree kev sib hloov, nta qis ntws tsis kam, thiab muaj qhov hnyav thiab qhov zoo ntawm qhov chaw hauv daim ntawv thov loj. Nws tus qauv tsim qhia txog kev ntseeg siab, nrog rau qee cov khoom lag luam uas tau ua tiav cov kev ntsuas lub zog thiab kev sim kom ntseeg tau tias muaj kev nyab xeeb hauv cov chaw tseem ceeb xws li cov khoom siv roj. Cov ntawv thov tseem ceeb suav nrog kev siv dej hauv nroog thiab kev kho cov dej khib nyiab, kev thauj mus los roj thiab roj, lub zog cog hluav taws xob, thiab cov txheej txheem kev lag luam.

Cov neeg yuav khoom nquag nug cov lus nug
Q1: Dab tsi yog qhov sib thooj US tus qauv (NPS) loj rau DN400 npauj npaim valve? ASME phaus chav kawm twg qhov ntsuas siab PN16 sib npaug li cas?
- A1:Raws li cov qauv thoob ntiaj teb, DN400 sib raug zoo rau NPS 16. Lub siab ntsuas PN16 feem ntau sib npaug rau ASME Chav Kawm 150. Txawm li cas los xij, kev xaiv zaum kawg yuav tsum nco ntsoov xav txog qhov ntsuas kub ua haujlwm -siab nkhaus.
Q2: Dab tsi yog qhov tseem ceeb ntawm WRAS daim ntawv pov thawj uas koj tau hais rau kev yuav khoom li qub rau cov dej haus?
- A2:WRAS (Water Regulations Advisory Scheme) kev pom zoo yog ib daim ntawv pov thawj muaj peev xwm heev. Nws pom tau tias cov khoom siv valve ua tau raws li cov qauv nruj rau cov khoom siv kev nyab xeeb thiab kev ua haujlwm ntawm kev sib cuag nrog cov dej haus. Rau cov neeg yuav khoom, xaiv 400mm Npauj Npaim Valve nrog kev pom zoo WRAS yog qhov tseem ceeb rau kev ua haujlwm kom ua raws li kev noj qab haus huv thiab kev nyab xeeb hauv Tebchaws Europe thiab ntau thaj tsam, txo qis kev pheej hmoo ntawm kev ua raws cai.
Q3: Thaum siv rau kev tswj kev khiav dej num, puas loj - txoj kab uas hla 400mm Npauj Npaim Valves ua rau cavitation, uas tuaj yeem cuam tshuam rau lub neej kev pabcuam?
- A3:Cavitation yog qhov tshwm sim tiag tiag uas yuav tsum tau saib xyuas hauv cov li qub, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej throttling. Cov qauv tsim tshiab tam sim no rau loj- kab ntsig npauj npaim li qub hais txog qhov no los ntawm kev ua kom zoo dua qub (piv txwv li, siv triple-offset design) thiab ntws hla los txhim kho qhov ntws thiab txo cov cavitation. Thaum xaiv, nws raug nquahu kom qhia meej qhov xav tau ntawm lub valve qhib qhov ntau thiab lub siab poob qis. Qhov no tso cai rau cov kws tshaj lij los ntsuas qhov kev pheej hmoo thiab pom zoo kom haum rau qhov zoo tshaj plaws disc thiab lub rooj foob hom kom txuas ntxiv lub neej kev pab cuam.
