ZDM Series Tsis Siv Neeg recirculation tswj valve
ZDM series Automatic recirculation valve yog ib hom twj tso kua mis tiv thaiv. Nws tsis siv neeg tiv thaiv lub twj tso kua mis centrifugal thaum lub twj tso kua mis lub cev tshwm sim cavitation tsis ruaj khov (tshwj xeeb tshaj yog xa dej kub ntawm kev ua haujlwm qis). Thaum lub twj tso kua mis ntws qis dua li qhov dej tau teev tseg, bypass tuaj yeem qhib tag nrho kom ntseeg tau tias lub twj tso kua mis tsawg kawg nkaus. Txawm tias khiav tag nrho kaw, uas yog khiav khiav yog xoom, qhov tsawg kawg nkaus ntws kuj tseem hla bypass rau Automatic recirculation. Siab txo los ntawm multistage bypass siab txo valve.
ZDM series yog tsim rau bypass nrog siab sib txawv, siab tshaj plaws sib txawv yog 30MPa, thiab kev xaiv tshwj xeeb yog txiav txim los ntawm lub Hoobkas. Multistage decompression hom M hom bypass tuaj yeem tshem tawm cov suab nrov los ntawm kev kub ceev nruab nrab, tiv thaiv kev puas tsuaj ntawm cavitation yaig thiab braising rau valve Cheebtsam.
• Tiv thaiv cavitation multistage decompression bypass, txo kev tshaj tawm, haum rau kev kub siab.
• Forged valve lub cev, lossis koj tuaj yeem xaiv cov khoom siv carbon steel lossis stainless hlau, thiab lwm yam.
• Txheem bypass tsis rov qab muaj nuj nqi, siab tshaj plaws ua hauj lwm siab sib txawv yog 30MPa.
• Qib siab ntawm PN16 txog PN420, txoj kab uas hla ntawm DN2 txog DN500.
• Muaj peev xwm xaiv phau ntawv hla kev ua haujlwm ua haujlwm, siv ua txhaum.
Valve lub cev hom: peb-txoj kev forged valve
Nominal txoj kab uas hla: 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)
Hom kev sib txuas kawg: Flange, FF, RF, RTJ, BW, SW thiab lwm yam.
Raws li qhov sib txawv ntawm inductive main flow, lub ntsiab valve disc check cone ntawm tsis siv neeg recirculation valve yuav cia li txav mus rau ib qho chaw. Nyob rau tib lub sij hawm lub ntsiab valve disc tsav bypass valve qia, hloov lub zog ntawm lub ntsiab valve disc rau bypass, los ntawm kev tswj bypass valve disc txoj hauj lwm, hloov bypass throttling cheeb tsam, thiaj li los tswj bypass ntws. Thaum lub ntsiab valve disc rov qab rau hauv lub rooj zaum kaw, tag nrho cov ntws rov qab los ntawm kev hla. Thaum lub ntsiab valve disc nce mus rau sab saum toj txoj hauj lwm, bypass yog tag nrho kaw, tag nrho cov ntws ntawm lub twj tso kua mis ntws mus rau txheej txheem system. Lub valve no tau teeb tsa plaub txoj haujlwm hauv ib lub cev.
• Flow perception: Tsis siv neeg recircution valve lub ntsiab valve disc yuav cia li perceive lub ntsiab ntws ntawm cov txheej txheem system, yog li raws li qhov txaus los txiav txim txoj hauj lwm ntawm lub ntsiab valve disc thiab bypass disc.
• Recirculation tswj: Tsis siv neeg recirculation valve tuaj yeem nqus tau twj tso kua mis ib txwm ua haujlwm yuav tsum tau tsawg kawg nkaus ntws mus rau hauv cov cuab yeej cia los ntawm kev hla, txhawm rau kho lub twj tso kua mis HQ charateristics, kom paub txog kev rov ua dua tshiab.
• Bypass multistage siab txo: bypass tswj system tuaj yeem txo qhov nruab nrab rov qab los ntawm lub qhov hluav taws xob siab siab kom tsim nyog rov qab mus rau cov khoom siv qis qis nrog lub suab qis me me.
• Kos: Tsis siv neeg recirculation valve kuj muaj cov nyhuv valve, tiv thaiv cov kua rov qab mus rau lub twj tso kua mis. Bypass non-return muaj nuj nqi yog tus qauv.
• Tshwj xeeb bypass loj tuaj yeem hloov kho. Qhov max flow rate ntawm bypass yog nyob rau max Kv tus nqi.
