Nta: Lub cev RF Flanged Pob Valve
RF sealing kev ua tau zoo:Lub 3 hli tsa lub ntsej muag ua kom lub siab siab ntawm lub gasket. Thaum siv cov kauv qhov txhab gaskets, nws muab kev sib khi zoo tshaj plaws rau PN40 nruab nrab - mus rau - cov tshuab siab.
Tshuab-Tawm pov thawj Stem:Lub qia yog tsim los nrog ib qho T- hom lub xub pwg nyom, sab hauv loaded. Qhov no ua kom lub qia tsis tuaj yeem raug tshem tawm ntawm lub cev txawm tias nyob rau hauv cov kab noj hniav loj heev.
Anti-Static Device:Lub caij nplooj ntoos hlav-loaded pob yog haum nruab nrab ntawm lub pob / qia thiab qia / lub cev kom ntseeg tau tias muaj hluav taws xob txuas ntxiv, tso tawm hluav taws xob zoo li qub thiab tiv thaiv cov nplaim taws hauv qhov chaw tawg.
Hluav taws kub-Safe Design:Nyob rau hauv qhov kev tshwm sim ntawm qhov hluav taws kub uas ua rau cov rooj zaum mos, lub pob raug thawb los ntawm lub siab tiv thaiv lub rooj zaum hlau thib ob ua ke rau hauv lub cev kom ua tiav lub foob ib ntus.
ISO 5211 Direct Mount Pad:Cov qauv tsim niaj hnub no feem ntau muaj cov qauv tsim flange, tso cai rau kev teeb tsa ncaj qha ntawm pneumatic lossis hluav taws xob actuators yam tsis tas yuav tsum muaj cov hlua txuas ntxiv.

FAQ
RF txhais li cas ntawm lub valve?
RFsawv rauTsa ntsej muag.
Nws yog hais txog lub flange tsim qhov twg lub gasket sealing nto yog elevated (feem ntau yog 3 hli los yog 1/16 ") saum lub ntsia liaj qhov rooj lub ntsej muag.
Dab tsi yog flanged pob valve siv rau?
Lub flanged pob valve feem ntau yog siv rautxhim khu kev qha on/off (shut-off) flow controlnyob rau hauv industrial piping systems. Vim hais tias cov flanged kawg yog bolted ncaj qha mus rau cov yeeb nkab, lawv yog cov kev xaiv rau:
Siab -Pressure & Loj Diameter Pipes:Flanges muab qhov muaj zog dua, xau ntau dua- tiv thaiv kev sib txuas dua li cov xov los yog welded pob qij txha hauv qhov hnyav - lub luag haujlwm ib puag ncig.
Kev tu yooj yim:Lub valve tuaj yeem yooj yim unbolted thiab tshem tawm los ntawm lub raj xa mus rau kev kho lossis hloov tsis tau txiav cov yeeb nkab.
Ntau hom Media:Lawv yog siv los lis kua, gases, thiab slurries hauv kev lag luam xws liroj thiab roj, tshuaj ua haujlwm, kho dej, thiab fais fab nroj tsuag.
Npuas-Tight Sealing:Lawv zoo tagnrho rau cov ntawv thov uas xav tau "zero- leakage" foob kom muaj kev nyab xeeb thiab tiv thaiv ib puag ncig.
