ZDM Series Tsis siv neeg recirculation tswj valve
ZDM series Tsis siv neeg recirculation valve yog ib hom twj tso kua mis tiv thaiv. Nws tsis siv neeg tiv thaiv centrifugal twj thaum lub twj tso kua mis lub cev tshwm sim cavitation puas tsuaj tsis ruaj khov (tshwj xeeb tshaj yog xa cov dej kub ntawm kev ua haujlwm qis). Thaum lub twj tso kua mis ntws qis dua qhov ua tau npaj, hla yuav qhib tag los xyuas kom lub twj tso tawm tsawg kawg uas yuav tsum tau ua. Txawm tias khiav nrawm kaw, namely khiav txaus yog xoom, qhov tsawg kawg nkaus ntws tawm kuj tuaj yeem hla dhau ntawm kev hla rau Qhov recirculation Tsis Siv Neeg. Siab txo los ntawm multistage bypass siab txo lub valve.
ZDM series yog tsim rau kev hla nrog lub siab hloov plawg, qhov siab tshaj qhov siab tsis txaus yog 30MPa, thiab kev xaiv tshwj xeeb yog txiav txim siab los ntawm lub hoobkas. Multistage decompression type M type bypass tuaj yeem tshem tawm cov suab nrov ua los ntawm kev kub ceev ntws nruab nrab, tiv thaiv kev puas tsuaj ntawm cavitation yaig thiab nres ntawm cov khoom sib xyaw valve.
• Tiv thaiv cavitation multistage decompression bypass, txo kev nrawm, haum rau kev ua haujlwm siab.
• Forged valve lub cev, lossis koj tuaj yeem xaiv carbon hlau lossis steel hlau, thiab lwm yam.
• Tus qauv bypass tsis ua haujlwm rov qab, qhov siab tshaj plaws ua haujlwm siab txawv yog 30MPa.
• Cov qib siab los ntawm PN16 txog PN420, taub los ntawm DN2 txog DN500.
• tuaj yeem xaiv phau ntawv bypass kev ua haujlwm ua haujlwm, siv hauv kev txhaum.
Valve lub cev hom: Peb-txoj kev forged valve
Cov taub loj: NPS1 "-20" (DN25, 32, 40, 50, 65, 80, 100, 200, 250, 300, 350, 400, 450, 500)
Nominal siab: CL150 # -2500 # (PN16, 25, 40, 64, 100, 160, 250, 420)
Xaus kev sib txuas hom: Flange, FF, RF, RTJ, BW, SW thiab lwm yam.
Raws li qhov sib txawv ntawm qhov tsis txaus sab hauv, lub ntsiab valve disc kos lub khob ntawm automatic recirculation valve yuav cia li txav mus rau ib txoj haujlwm. Nyob rau tib lub sijhawm lub ntsiab valve nres tsav bypass valve kav, hloov txoj kev txav ntawm lub ntsiab valve disc rau bypass, los ntawm kev tswj bypass valve disc txoj hauj lwm, hloov bypass throttling thaj chaw, thiaj li tswj kom hla txoj kev ntws. Thaum lub ntsiab valve rov qab rau hauv lub rooj zaum valve kaw, txhua ntws rov qab los ntawm kev hla. Thaum tseem ceeb valve disc nce mus rau qhov chaw siab kawg, bypass kaw tag nrho, tag nrho cov ntws ntawm lub twj tso kua mis ntws mus rau txheej txheem system. Lub khob no teeb tsa plaub lub luag haujlwm hauv ib lub cev.
• Flow xaav: Tsis siv neeg recircution valve lub ntsiab valve disc tuaj yeem pom qhov tseem ceeb ntawm cov txheej txheem system, yog li raws cov ntws los txiav txim qhov chaw ntawm lub ntsiab valve disc thiab bypass disc.
• Kev tswj rov qab: Tsis siv neeg recirculation valve tuaj yeem nqus cov twj tso kua mis ib txwm ua haujlwm yuav tsum tau ntws tsawg mus rau hauv lub twj tso kua mis hla dhau, thiaj li kho cov twj tso kua mis HQ charateristics, kom paub txog kev rov ua dua tshiab.
• Bypass multistage pressure txo: bypass tswj lub tshuab tuaj yeem txo qhov nruab nrab thaub qab los ntawm lub siab tawm qhov hluav taws xob qhov hluav taws xob rau qhov tsim nyog rov qab los rau kev ua kom lub siab ntim qis nrog cov suab nrov me me hnav.
• Tshawb xyuas: Tsis siv neeg recirculation valve tseem muaj cov nyhuv valve, tiv thaiv cov kua rov qab rau lub cev. Bypass tsis rov qab los ua haujlwm yog tus qauv.
• Qhov tshwj xeeb bypass loj tuaj yeem kho tau. Tus nqi ntws ntawm bypass yog raug rau tus nqi max Kv.
