Zhongfa Valve yog cov chaw tsim khoom lag luam ntawm npauj npaim valve qhov chaw thiab npauj npaim li qub, tsim nyob rau xyoo 2006, muab cov khoom qub thiab npauj npaim valve yam khoom rau ntau tshaj 20 lub teb chaws hauv ntiaj teb, tom ntej no, Zhongfa Valve yuav tshaj tawm cov ncauj lus kom ntxaws ntawm npauj npaim valve qhov chaw.
Lub npauj npaim valve muaj cov nram qab no, lub npe npauj npaim lub npe yog lub cev lub cev, valve Disc, valve ncej, lub rooj zaum valve, sealing nto, thiab kev ua haujlwm actuator, tam sim no, peb yuav qhia cov npauj npaim valve qhov chaw ib los ntawm ib qho.
#1 Npauj Npaim valve qhov chaw--Valve lub cev
Peb tham txog lub valve lub cev hais txog kev sib txuas thiab cov khoom siv
1. Feem ntau hais lus, raws li cov kev sib txuas sib txawv, npauj npaim li qub muaj flange hom, hom wafer, thiab hom lug, thiab cov qauv kwv yees tau pom hauv daim duab.Rau txhua hom kev sib txuas, muaj qhov sib txawv me me raws li cov pwm sib txawv, xws li rau wafer npauj npaim valve, Zhongfa Valve muaj cov pwm hauv qab no.
2. Raws li cov khoom siv, cov khoom siv feem ntau yog lub cev hlau hlau, carbon steel lub cev, stainless hlau lub cev, tooj dag lub cev, thiab super duplex steel lub cev.
#2Npauj npaim valve qhov chaw ---Valve Disc
Cov style ntawm valve disc kuj txawv, tus pin disc, pinless disc, disc nrog roj hmab, Disc nrog Nylon, Electroplated Disc, thiab lwm yam, Feem ntau, lub valve disc raug xaiv raws li kev ua haujlwm thiab nruab nrab.
Rau lub pinless disc, Muaj ib tug los ntawm ncej thiab ob tug ncej, disc tsis muaj ib tug pin yuav txo tau cov kev pheej hmoo ntawm to, rau lub disc nrog ib tug pin, nws yog zoo li tus pin tau hnav los yog xeb tom qab ntev, lub media los ntawm tus pin ntawm lub disc uas xau ncej qhov.Peb xav xaiv tus pinless disc rau peb cov neeg siv khoom.
#3 Npauj Npaim valve qhov chaw--Valve Spindle
Npauj npaim valve spindle tseem hu ua qia, yog siv rau kev sib kis, txuas nrog lub actuator lossis kov, cov nram qab no ncaj qha tsav lub valve phaj tig, thiaj li ua tiav lub npauj npaim valve hloov lossis hloov lub luag haujlwm.
1. Los ntawm cov khoom siv: Cov khoom siv spindle feem ntau yog ua los ntawm stainless hlau thiab carbon hlau, thiab nws cov cai yog: stainless hlau (2cr13, 304, 316, 316L), carbon steel (35, 45, Q235).
2. Los ntawm cov style: npauj npaim valve los ntawm ncej (sab laug) thiab npauj npaim valve ob ib nrab ncej (txoj cai).
a: Nyob rau hauv cov nqe lus ntawm tus nqi: ib tug ob peb ib nrab-ncej yog kim tshaj ib tug los ntawm-shaft.
b: Nyob rau hauv cov nqe lus ntawm kev siv: ob tug ib nrab-ncej tuaj yeem ua tau ntau dua DN300, thiab los ntawm-ncej tuaj yeem ua DN800.
c: Fittings versatility: los ntawm-shaft fittings tuaj yeem siv rau ntawm pinned npauj npaim li qub nrog tus nqi qis.Tsuas yog ob lub taub hau npauj npaim li qub tuaj yeem siv tau, thiab cov khoom seem yog siab.
d: Kev sib dhos: los ntawm-ncej yam tsis muaj tus pin yog txoj hauv kev tsim qauv, tsim qauv yooj yim, ua haujlwm ncej, ob npaug ib nrab-ncej tsim teeb meem, feem ntau muab faib ua cov ncej sab saud, thiab qis dua.
#4 Npauj Npaim valve qhov chaw--Valve Seat
Lub rooj zaum roj hmab ntawm lub qhov muag muag npauj npaim valve tuaj yeem muab faib ua lub rooj zaum tawv-rov qab thiab cov roj hmab muag muag, thiab lub rooj zaum ntawm lub qhov rooj tawv tawv npauj npaim valve feem ntau yog cov foob foob thiab ntau theem foob.
Qhov sib txawv ntawm lub rooj zaum roj hmab tawv tawv thiab cov roj hmab muag muag ntawm lub rooj zaum ntawm npauj npaim valve: lub rooj zaum tawv nraub qaum yog nias rau ntawm lub valve lub cev nrog cov abrasives, uas tsis tuaj yeem hloov tau los ntawm nws tus kheej thiab yuav tsum muaj qhov tshwj xeeb flange rau npauj npaim valve. ;lub rooj zaum muag muag yog tsim los ntawm cov qauv, uas tuaj yeem hloov tau los ntawm nws tus kheej thiab tuaj yeem siv nrog flange uas tsis yog tshwj xeeb rau npauj npaim valve.
Nyob rau hauv cov nqe lus ntawm roj hmab rooj zaum kev pab cuam lub neej, lub neej kev pab cuam ntawm lub soft back seat yog ntev dua li ntawm lub rooj zaum tawv, uas yog ib tug loj broadside qauv.Valve lub sijhawm ua haujlwm ntev txheej txheem valve rooj zaum kawg hnav.Valve lub rooj zaum kawg to tom qab lub zog rov qab lub rooj dej seepage ncaj qha mus rau sab nraum lub valve lub cev to phenomenon.Tab sis qhov muag muag tsis tshwm sim hauv qhov xwm txheej no.
#5 Npauj Npaim valve qhov chaw--Sealing nto
muaj soft sealing thiab hard sealing,Kev xaiv ntawm cov ntaub ntawv mos sealing:
1, Roj Hmab (xws li roj hmab butadiene, EPDM roj hmab, thiab lwm yam), feem ntau yog siv hauv cov kav dej uas tsis tshua muaj siab tshaj cov roj thiab dej.
2, Yas (PTFE, nylon, thiab lwm yam), ntau rau corrosive media hauv cov kav dej.
Kev ua haujlwm hom: kov, turbo, hluav taws xob, pneumatic, hydraulic
Kev xaiv cov ntaub ntawv nyuaj sealing:
1 、 Copper alloy (rau qhov qis qis)
2, Chrome stainless hlau (rau zoo tib yam siab thiab nruab nrab siab li qub)
3 、 Stellite alloy (rau qhov kub thiab txias li qub thiab muaj zog corrosive li qub)
4, Nickel-raws li alloys (rau corrosive media)
#6 Npauj Npaim valve qhov chaw--Kev ua haujlwm Actuator
Npauj npaim li qub feem ntau yog ua haujlwm hauv qab no, Tes Lever, Worm Gear, Pneumatic Actuator.
Tes levers feem ntau yog ua los ntawm nruj, tshuaj kho, thiab hmoov coated.Lub tes taw tes feem ntau muaj ib tug kov thiab ib tug interlocking lever, Nws yog haum rau DN40-DN250.
Cov iav iav yog tsim rau cov npauj npaim loj li qub.Cov cab cab iav feem ntau siv rau qhov loj dua DN250, tseem muaj ob-theem thiab peb-theem turbine thawv.
Pneumatic actuators muab faib ua ob pawg, ib leeg ua yeeb yam thiab ob leeg ua yeeb yam pneumatic actuators.
Hluav taws xob actuators tuaj yeem muab faib ua ntau hom tig thiab ib feem tig.Multi-tig hom tig ntau tshaj 360 ° qhib thiab kaw lub valve thaum lub sij hawm tig hom tig ib txwm 90 ° kom qhib thiab kaw lub valve.
Tom ntej no, cia peb saib yuav ua li cas rau nruab tus npauj npaim valve qhov chaw ua ke
