WCB viav vias kos valve yog kev lag luam -qib unidirectional flow control device tsim los ntawmASTM A 216 WCBcam khwb cia carbon steel raws liSIB 1868los yogAPI 6D UAScov qauv; Nws ua haujlwm los ntawm kev siv cov dej siab los thawb qhib lub disc uas swings nyob rau hauv ib qho arc nyob ib ncig ntawm lub pob khawm, kaw cia li ntawm lub ntiajteb txawj nqus thiab backpressure thaum ntws los yog thim rov qab.
Feem ntau featuringAPI Trim 8(13Cr stainless hlau nrog Stellite hardfacing) rau durability nyob rau hauv ib puag ncig xws li-29℃rau 425 degree, lub valve no yog tus yam ntxwv los ntawm nws tag nrho -ntoo tsim- muab lub siab ntws coefficient (Cv ntawm kwv yees li 2000 rau DN200) thiab qis tawg siab (0.03-0.05 MPa)- ua kom nws yog ib qho tseem ceeb hauv cov roj, roj, thiab cov kav dej saturated los tiv thaiv kev rov qab los thiab txo cov dej rauj kev puas tsuaj.
Ua raws li BS 1868 & API 598 xeem.Nyem qhov no txhawm rau thov peb cov ntawv pov thawj zoo thiab cov ntawv xeem.

Kev tsim kho
Cov qauv sab hauv ntawm lub viav vias kos valve muaj cov hauv qab no:
Lub cev Valve:Ib qho WCB cam khwb cia steel tivthaiv featuring ib tug streamlined ntws txoj kev kom txo tau siab poob.
Bonnet:Txuas nrog lub cev ntawm bolts, tso cai rau kev saib xyuas yooj yim thiab hloov cov khoom sab hauv.
Disc:Qhov tseem ceeb txav feem uas tig. Nws feem ntau yog nruab nrog lub sealing nto (xws li, 13Cr lossis Stellite hardfacing).
Hniav npab:Cov khoom uas txuas lub disc mus rau lub pob khawm.
Hinge Pin:Tsau nyob rau hauv lub valve lub cev, muab lub axis nyob ib ncig ntawm lub disc rotates.
Rooj Ring:Lub rooj zaum valve sealing nto, feem ntau ua nrog stainless hlau hardfacing.
Gasket:Xyuas kom lub foob ntawm lub cev thiab lub kaus mom (feem ntau yog ib lub qhov txhab ntawm lub qhov txhab).

Nta
Tsawg Flow Resistance:Nyob rau hauv txoj hauj lwm qhib tag nrho, txoj kev khiav yuav luag tsis muaj kev cuam tshuam, uas ua rau qis qis dua piv rau nqa cov tshev valve.
Txhim khu kev sealing:Lub disc yog nias nruj nreem rau lub rooj zaum los ntawm backpressure ntawm nruab nrab; siab dua ua rau lub foob nruj dua.
Flexible Installation:Nws tuaj yeem ntsia tau kab rov tav lossis ntsug ntawm cov kav dej uas qhov nruab nrab ntws los ntawm qab mus rau saum.
Durability:Cov khoom siv WCB tiv taus qhov kub thiab txias. Ua ke nrog hardfaced sealing nto, nws yog heev resistant rau yaig thiab muab ib tug ntev kev pab cuam lub neej.
Internal Hinge Pin Design:Cov qauv tsim niaj hnub no feem ntau siv tus pin sab hauv, uas txo cov ntsiab lus tawm sab nraud (tsis muaj tus pin sab nraud).

FAQ
Dab tsi yog qhov teeb meem nrog viav vias kos li qub?
Lub viav vias kos valve muaj plaub qhov kev ua tau zoo tshaj plaws:
Dej rauj (Slamming):Lub disc slams kaw nruj heev thaum ntws rov qab, ua rau muaj kev kub ntxhov loj heev uas tuaj yeem cuam tshuam cov kav dej lossis kev txhawb nqa.
Disc sib tham:Nyob rau hauv qis- khiav nrawm, lub disc "hovers" thiab vibrates, uas sai sai hnav lub pob khawm tus pin thiab tuaj yeem ua rau lub disc kom tshem tawm.
Hinge Misalignment:Kev sib txhuam tsis tu ncua ua rau tus pin thaum lub sij hawm, ua rau lub disc kom sag thiab ua tsis tau zoo rau lub rooj zaum.
Debris Traping:Hauv qab ntawm lub cev lub cev ua raws li "lub hnab tshos" qhov twg cov av qeeg los yog nplai sau, feem ntau tiv thaiv lub disc los ntawm kev kaw tag nrho.
WCB txhais li cas ntawm li qub?
WCB yogcam khwb cia carbon steel, whereas nws forged counterpart yog A105. Thaum cim rau ntawm lub valve, nws qhia txog cov khoom ntawm lub valve lub cev. WCB yog qib Asmeskas, sib npaug rau hauv Suav qib ZG280-520.
Koj puas tuaj yeem qhib lub viav vias kos valve?
Kev ua haujlwm ntawm viav vias kos valve feem ntau poob rau hauv ob pawg:phau ntawvthiabtsis siv neeg. Cov txheej txheem tshwj xeeb ua haujlwm nyob ntawm qhov yuav tsum tau ua ntawm daim ntawv thov scenario.
Raumanually ua viav vias kos li qub, qhib thiab kaw yog actuated ntawm tes crank, handwheel, los yog lwm yam phau ntawv mechanisms. Hom kev ua haujlwm no yog tsim rau cov xwm txheej uas lub sijhawm meej ntawm qhov kev ua haujlwm ntawm lub valve tsis yog qhov tseem ceeb, cov dej ntws tau qis, thiab qhov chaw ua haujlwm yog qhov yooj yim.
