Valves rau molten sulfur lossis sulfur tail gas daim ntawv thov-Lub Yim Hli 2019-Valves thiab Automation

Zwick tus tsim engineers tau daws cov teeb meem tsis tu ncua uas tau ntsib los ntawm cov li qub ntawm cov nroj tsuag leej faj. Ntawm cov kav dej loj loj, cov teeb meem valve feem ntau los ntawm cov ntsaws ruaj ruaj mus rau qhov kev puas tsuaj loj ntawm lub rooj zaum (thaum lub valve yuav tsum tau ua haujlwm tom qab lub sijhawm tsis ua haujlwm ntev). Lub valve yuav tsum raug xaiv los ua ib lub tsho sov vim tias qhov no yog qhov yuav tsum tau muaj lub valve ntawm tus qauv. Feem ntau, cov txheej txheem valve yuav tsim nyog rau cov kav dej zoo tshaj plaws uas yuav tsis muaj kev poob qis lossis ua pob, vim tias ib zaug lub valve lub cev kub nce mus txog lub cev kub ntawm cov sulfur los yog cov pa tso tawm los ntawm nws, tsis muaj kev ruaj ntseg yuav raug tso cai. Thaum lub valve lub cev kuj tseem txias vim yog sulfur txias, qhov teeb meem txawv txav tshwm sim, uas tom qab ntawd solidifies nyob rau hauv cov kabmob / ncej, yog li jamming cov ntsiab lus. Raws li kev paub thoob ntiaj teb, Zwick engineers pom zoo kom siv lub tshuab ua pa nrog lub valve vim tias lawv tuaj yeem khaws cov chaw tseem ceeb ntawm qhov kub thiab txias, yog li tshem tawm cov qaug dab peg. Lub tuam txhab tuaj yeem muab cov wafer thiab ob lub flange li qub nrog lub tsho ua haujlwm, thiab peb tuaj yeem siv cov khoom siv hluav taws xob taug qab valve trims (stem thiab disc). Zwick Tri-Con series li qub tau nruab nrog cov kabmob tiv thaiv, uas tuaj yeem txo qhov nruab nrab nkag mus rau qhov chaw tseem ceeb, ntxiv rau qhov chaw nres nkoj dej ntws tawm, ua kom muaj kev tu thiab tiv thaiv cov chaw tseem ceeb no. Cov lus piav qhia hauv qab no qhia txog cov kev sib txawv ntawm Zwick Tri-Con valve thiab lwm hom (los ntawm ob chav eccentric valve mus rau jacketless valve), uas yuav ua tsis tau raws li hom ntawv thov no. Tri-Con series yog tsim tshwj xeeb uas tsim cov txheej txheem kev sib cais, qhib / tawm thiab tswj li qub. Nws ntau yam kev siv tsuas yog txwv los ntawm cov khoom siv tiag tiag. Qhov tseeb, cov li qub uas tsim los ntawm Zwick yog tsim rau qhov kub ntawm -196ºC mus rau siab dua rau +815ºC. Valves tuaj yeem tsim nyob rau hauv txhua daim ntawv machinable alloy kom tau raws li cov neeg siv khoom tshwj xeeb. Lub Zwick Tri-Con series yog triple eccentric valve nrog lub khob hliav qab tiag tiag thiab tsim lub khob hliav qab, uas tuaj yeem tshem tawm txhua qhov kev sib txhuam ntawm lub rooj zaum valve, yog li tshem tawm txhua yam hnav uas yuav ua rau kom tawg. Rau lwm cov kev ua tau zoo li qub, qhov no yog technically tsis yooj yim sua, xws li ob chav eccentric tsim. Raws li lub sijhawm dhau mus, qhov kawg 15-18º kev sib txhuam foob yuav xau. Ob chav eccentric li qub tsis haum rau cov kev thov no. Yog li ntawd, txhua qhov kev sim siv lawv yuav ua rau muaj teeb meem tshwm sim. Self-centering disc: Nrog nws tus kheej-centering kub them nyiaj disc, lub Tri-Con series qauv tuaj yeem ua kom txoj haujlwm zoo tshaj plaws ntawm laminated foob txheeb ze rau lub rooj zaum valve. Yog li ntawd, kev cuam tshuam los ntawm thermal expansion yog tshem tawm. Torque kis tau tus mob nrog cov yuam sij: Lub disc yog keyed rau lub ncej thiab tsis yog tsau, muab ib tug uniform torque kis tau tus mob thiab tshem tawm txoj kev pheej hmoo ntawm pins ntog. Qhov zoo tshaj plaws zaj duab xis thiab disc tsim: Cov khoom disc thiab nws cov elliptical txhawb nto muab cov yeeb yaj kiab zoo tshaj plaws. Los ntawm kev ua tshwj xeeb ntawm laminates, xoom xau tuaj yeem ua tiav. Kev them nyiaj yug bearing bushing: Qhov zoo tshaj plaws txoj hauj lwm ntawm cov kabmob txo cov dabtsi yog khoov ntawm ncej. Qhov no tuaj yeem ua kom muaj ob txoj kev sib khi hauv qab qhov siab tshaj plaws.
