A216 WCB Hlau -Seated Floating Ball Valveyog kev lag luam kaw -off valve precision-engineered rau cov kev pabcuam hnyav uas muaj qhov kub thiab txias, siab siab, thiab cov khoom abrasive. Nws lub cev, nrum los ntawmASTM A216 WCB carbon hlau, muab cov khoom siv tshwj xeeb tshwj xeeb rau cov tsis yog -corrosive media ntawm kev ua haujlwm kub txog li425 degree.
Tawm ntawm ib txwm mos- qauv tsim, lub valve no muaj ibhlau-rau- hlausealing architecture, nrog pob thiab lub rooj zaum qhov chaw hardened los ntawmSiab -Cov pa hluav taws xob nrawm nrawm (HVOF)txau ntawmTungsten Carbide los yog Stellite alloyskom ua tiav qhov hardness tshajHRC 60. Qhov kev kho tshwj xeeb no muab kev tiv thaiv zoo tshaj rau kev yaig, puas, thiab galling.
Los ntawm kev siv lub pob ntab lub siab-vim kev txav chaw ua ke nrog aBelleville caij nplooj ntoos hlav-compensated seattsim, lub valve zoo txo lub pob jamming tshwm sim los ntawm thermal expansion thaum ua kom nruj kaw -tawm kev ua raws liANSI / FCI 70-2 Chav Kawm V lossis VI. Nws yog qhov kev daws teeb meem zoo tshaj plaws rau cov chav superheated, mining slurries, thiab roj av coking, qhov twg tus qauv mos- zaum li qub feem ntau yuav ua tsis tiav.

A216 WCB Hlau -Seated Floating Ball Valve Nta
Muaj peev xwm ua haujlwm hnyav:Tsim los nrog cov hlau-rau- hlau rooj zaum architecture, nws tuaj yeem tiv taus qhov kub thiab txias (txog 425 degree) thiab cov kev kub ntxhov uas yuav ua kom puas cov qauv muag muag (xws li PTFE).
Exceptional Erosion Resistance:Lub pob thiab lub rooj zaum yog coated nrog HVOF Tungsten Carbide, tsim kom muaj qhov tawv tawv heev. Nws tuaj yeem yooj yim shear los ntawm kev tshaj tawm uas muaj cov khoom catalyst, grit, lossis crystals yam tsis muaj kev puas tsuaj rau kev sib khi.
Thermal Expansion Compensation:Lub rooj zaum yog rov qab los ntawmBelleville Springs: koj puas xav tau ntau tus thwjtim?. Thaum lub pob nthuav dav ntawm qhov kub thiab txias, cov springs nqus cov kev txav mus los tiv thaiv lub pob los ntawm kev txeeb los yog jamming, kom ntseeg tau tias torque du.
Lub neej ua haujlwm ntev:Nyob rau hauv abrasive los yog siab -kub media, hlau- zaum li qub feem ntau kav 3 mus rau 5 npaug ntev dua li mos- zaum lwm txoj.
Intrinsic Fire Safety:Qhov tsis muaj cov ntaub ntawv mos mos ua rau nws muaj hluav taws kub - nyab xeeb. Nws kuj suav nrog cov khoom siv tiv thaiv- zoo li qub thiab tiv thaiv- lub tshuab tawg raws li tus qauv.

FAQ
Qhov txawv ntawm A216 WCC thiab A216 WCB yog dab tsi?
Qhov sib txawv tseem ceeb ntawmA216 WCBthiabA216 WCCyogzogthiabtawv:
Lub zog: WCCmuaj zog dua. Nws muaj lub zog tawm los ntau dua (tsawg kawg40,000 psi) piv rauWCB(yam tsawg kawg36,000 psi).
Tshuaj muaj pes tsawg leeg:WCC muaj qhov tsawg tshaj plaws carbon txwv (0.25%) tab sis siab dua manganese dua WCB (0.30% carbon). Qhov no ua rau WCC yooj yim dua rau vuam thiab tawv dua.
Tsawg-Kev Ua Haujlwm Kub:WCC feem ntau muaj kev cuam tshuam zoo ntawm qhov kub qis dua WCB.
Nrov nrov: WCByog qib "standard" tshaj plaws thoob ntiaj teb;WCCyog siv thaum engineers xav tau lub zog ntxiv los yog kev ua tau zoo dua nyob rau hauv siab dua - kev siv siab.
WCB pob valve yog dab tsi?
A WCB pob valveyog ib qho kev lag luam valve ua los ntawmcam khwb cia carbon steel(Tshwj xeeb ASTM A216 Qib WCB).
WCB sawv rau dab tsi hauv li qub?
Hauv kev lag luam valve,WCBsawv rau:
W: Weldable (tsim rau vuam rau hauv cov kav dej).
