1. Lub PTFE Fully Lined Butterfly Valve yog dab tsi?
PTFE (polytetrafluoroethylene) cov npauj npaim puv nkaus siv dav hauv cov kav dej rau cov xov xwm corrosive heev (xws li cov kua qaub muaj zog, cov hauv paus muaj zog, thiab cov kuab tshuaj organic) vim tias ob qho tib si lub cev valve thiab disc yog tag nrho nrog PTFE, muab kev tiv thaiv corrosion zoo heev thiab kev ua haujlwm sealing. Cov qauv ntawm lub cev valve feem ntau muab faib ua ob hom: ob daim (lub cev sib cais) thiab ib daim lub cev. Lubob daim qauvyog tus qauv tsim tseem ceeb rau PTFE cov npauj npaim uas muaj cov kab sib txuas tag nrho, thaum tus qauv tsim ib daim tsis tshua muaj, feem ntau yog vim muaj kev txwv hauv cov txheej txheem sib txuas.
2. Kev Zoo Sib Xws
Loj:DN50-DN600. Tsis zoo li cov npauj npaim ib txwm muaj nrog cov rooj zaum EPDM, qhov tsawg kawg nkaus rau cov rooj zaum PTFE yog DN50.
Siab:Txwv los ntawm cov khoom siv PTFE, tshwj xeeb tshaj yog cov PTFE-lined disc, nws yog tsim rau qhov siab tshaj plaws ntawm PN10 (PN16 xav tau cov lus qhia tshwj xeeb).
Kub:Kub ua haujlwm yog -10 txog 180 degrees Celsius. (RPTFE feem ntau yog -20 txog 200 degrees Celsius)
3. Qhov Txawv Tseem Ceeb thiab Kev Sib Piv
3.1 Cov yam ntxwv ntawm cov qauv
Ob daimLub cev(Lub cev sib cais)Lub cev valve muaj ob lub halves (lossis ob daim) sib dhos thiab txuas nrog los ntawm bolts. Lub hauv paus yog tsim rau txhua ib nrab sib cais ua ntej sib dhos.
Ib Daim Lub Cev (Tag Nrho Lub Cev):Lub cev valve yog cast los yog machined ua ib daim, thiab lub hauv ob sab hauv yuav tsum tau txhaj tshuaj molding los yog ib qho txheej txheem tshwj xeeb rau kev encapsulation tiav.
3.2 Cov Txheej Txheem Tsim Khoom
Lub cev valve faib ua ob ntu:Lub cev valve muaj cov khoom sab saud thiab sab hauv qab txuas nrog los ntawm cov ntsia hlau. Lub PTFE sab hauv (xws li cov nplhaib silicone) feem ntau yog tsim sib cais ua ntej sib dhos. Yog li ntawd, cov txheej txheem sab hauv rau lub cev ob daim yooj yim dua thiab tsis xav tau cov pwm tshwj xeeb lossis cov cuab yeej rau kev sib dhos.
Tag Nrholub cev valve npauj npaimLub cev valve yog casting los yog machined ua ib daim, tsis muaj qhov sib koom ua ke nruab nrab. Lub PTFE hauv ob sab hauv yog integrated nrog lub cev valve los ntawm kev molding lossis sintering.
3.3 Kev Ua Haujlwm Sealing
Ob daim (Lub cev sib cais):Tsis muaj qhov xau ob sab (ua npuas), tab sis qhov sib koom ua ke yuav tsum muaj kev tsim kom zoo (xws li O-rings lossis gaskets).
Ib daim (tag nrho lub cev): Tsis muaj qhov sib koom ua ke, tsawg dua qhov xau, thiab kev ntseeg siab ntawm kev sib khi.
3.4 Qhov Loj Siv Tau
Ob daim (Faib Lub Cev):Feem ntau muaj nyob rau hauv DN50 ~ DN600, thiab txawm tias qhov loj dua kuj yooj yim ua tiav.
Ib daim (Monoblock Lub cev)Feem ntau tsuas yog siv rau cov qhov me me xwb; cov qhov loj dua nyuaj rau tsim.
3.5 Yooj Yim Kho
Ob daim npauj npaim valve lub cev:Zoo heev: Yooj yim rau disassemble, tsis tas yuav muaj cov cuab yeej tshwj xeeb, thiab cov ntaub thaiv ib nrab lossis lub npauj npaim disc tuaj yeem hloov pauv ib tus zuj zus, ua rau kev saib xyuas yooj yim.
Ib daim npauj npaim valve lub cev:Tsis Zoo: Nyuaj kho hauv zos thaum lub txheej puas lawm; feem ntau yuav tsum tau hloov tag nrho lub cev valve.
3.6 Tus nqi
Ob daim:Siab dua, lub rooj zaum PTFE muaj lub nplhaib silicone sab hauv kom nce elasticity thiab sealing kev ua tau zoo.
Ib daimQis dua, txawm hais tias cov txheej txheem sab hauv yog qhov nyuaj (PTFE muaj qhov tsis zoo elasticity thiab nyuaj rau txhaj tshuaj sib npaug rau hauv ib daim valve lub cev), thiab kev tsim khoom yog qhov nyuaj, peb lub tuam txhab muaj cov thev naus laus zis paub tab, ua rau tus nqi qis dua.
3.7 Cov Xwm Txheej Thov
Ob daim : Qhov kev xaiv tseem ceeb, feem ntau yog siv rau hauv cov kav dej tshuaj lom neeg, tshuaj, dej khib nyiab, thiab cov kav dej corrosive.
Ib daimSiv rau hauv cov ntawv thov tshwj xeeb uas xav tau kev pab ntau (xws li qhov yuav tsum tau kaw ruaj khov heev thiab tsis tas yuav tsum tau saib xyuas), tab sis tsis tshua siv rau hauv PTFE cov li qub uas muaj cov kab npauj npaim puv nkaus.
