Wedge gate valves yuav raug ntsia rau ntawm kab rov tav thiab ntsug kav, tab sis cov kev taw qhia ntawm kev teeb tsa yuav tsum raug xaiv raws li kev ua haujlwm tshwj xeeb thiab cov qauv tsim los xyuas kom meej sealing kev ua tau zoo, kev ua haujlwm ruaj khov thiab ntev -lub sijhawm ruaj khov. Ntawm no yog ib qho kev sib cais:
I. Kab rov tav Pipeline Installation: Mainstream Application Scenarios
Kev siv tau: Lub qhov rooj qhov rooj feem ntau yog siv rau kab rov tav kev teeb tsa, tshwj xeeb tshaj yog nyob rau hauv qab no:
Siab-siab, siab- qhov kub thiab txias (piv txwv li, ntev- cov roj thiab cov kav dej sib txawv): Nrog rau kab rov tav installation, qhov hnyav ntawm lub rooj vag muaj qhov cuam tshuam me ntsis ntawm qhov sib khi. wedge qauv tuaj yeem sib txawv ntawm qhov sib txawv ntawm qhov nruab nrab, tsim kom muaj kev ruaj ntseg ntawm tus kheej - zawm foob.
Cov kav dej uas muaj cov khoom siv hauv nruab nrab (xws li kev kho dej phwj tuaj, kev thauj mus los slurry): los ntawm kev teeb tsa kab rov tav, cov khoom siv hauv nruab nrab tsis tshua muaj kev sib sau ntawm lub rooj vag thiab lub rooj zaum valve, txo qhov kev pheej hmoo ntawm kev hnav thiab txhaws.
Cov ntawv thov uas yuav tsum tau qhib thiab kaw ntau zaus (xws li kev tswj cov txheej txheem tshuaj lom neeg): Nrog kab rov tav mounting, valve qia tsav torque yog ntau dua, kev ua haujlwm qis dua, thiab kev tswj tsis siv neeg (xws li, hluav taws xob lossis pneumatic actuation) yooj yim dua. Kev Tiv Thaiv Kev Tiv Thaiv:
Ntawm qhov nkag ntawm lub valve, qee qhov ntev ntawm cov yeeb nkab ncaj (feem ntau yog 5 npaug ntawm txoj kab uas hla ntawm cov yeeb nkab) yuav tsum tau khaws cia kom txo tau cov nyhuv ntawm cov xov xwm turbulent ntawm lub sealing nto.
Ib qho dej ntws yuav tsum muab rau hauv qab ntawm lub valve kom ntws tawm cov xov xwm thaum kaw kom tsis txhob xeb lossis khov.
II. Vertical Pipeline Installation: xaiv raws li kev siv tshwj xeeb.
Scope ntawm daim ntawv thov: Wedge gate li qub mounted rau ntsug kav yuav tsum tau raws li nram no tej yam kev mob:
Dielectric flow upward (xws li, boiler feedwater system): Dielectric siab tuaj yeem pab lub rooj vag sealing thiab lub rooj zaum valve, txhim kho sealing nyhuv.
Piv txwv li, vertically ntsia lub rooj vag li qub nyob rau hauv boiler feedwater pipelines nyob rau hauv cov thee- hluav taws xob fais fab nroj tsuag siv dej siab rau nws tus kheej- sealing, txo txoj kev pheej hmoo ntawm to.
Qhov chaw txwv lossis cov raj xa dej yuav tsum tau ua (xws li cov kav dej hauv av, thaj chaw cov khoom siv sib cog lus): Vertical installation txuag qhov chaw kab rov tav thiab tsim nyog rau qhov chaw nyob ib puag ncig.
Bidirectional sealing yuav tsum tau (piv txwv li, nuclear fais fab nroj tsuag dej txias tshuab rau nuclear fais fab nroj tsuag): Qee lub qhov rooj vag valve yog tsim los muab ntim rau hauv ob qho tib si cov lus qhia thiab, thaum ntsia vertically, tuaj yeem tiv taus ob qho tib si ntsug thiab kab rov tav xov xwm siab kom muaj kev nyab xeeb.
Kev Tiv Thaiv Kev Tiv Thaiv:
Lub rooj vag nws tus kheej qhov hnyav yuav ua rau eccentricity ntawm lub sealing nto, uas yuav tsum tau them nyiaj los ntawm cov springs los yog cov ces kaum (xws li, ib tug resilient rooj vag qauv).
Thaum qhov nruab nrab ntws mus rau hauv qab, lub qhov cua valve yuav tsum tau ntsia saum lub valve kom tsis txhob muaj cua tsis kam thiab ua haujlwm nyuaj.
Thaum tsis siv rau lub sijhawm ntev, lub rooj vag yuav tsum muab tso rau hauv ib nrab -qhib txoj hauj lwm los tiv thaiv lub ntiajteb txawj nqus- ntxias cov foob deformation.
III. Cov qauv tsim tseem ceeb cuam tshuam rau kev teeb tsa kev taw qhia
Hom rooj vag:
Resilient Gate: Kev them nyiaj rau thermal expansion lossis installation deviations vim nws tus kheej deformation; haum rau ntsug installation (xws li, boiler feedwater li qub).
Ob chav rooj vag: Split tsim, tsis siv neeg centering kom txo tau gravitational cuam tshuam; haum rau txoj kab uas hla loj ntsug yeeb nkab.
Lub rooj zaum:
Lub rooj zaum tawv tawv (xws li hlau rau hlau) yog rhiab rau mounting kev taw qhia; uniform nruab nrab siab faib yuav tsum tau guaranteed.
Cov rooj sib khi mos mos (xws li cov roj hmab hauv ob sab phlu) tuaj yeem ua kom haum lub kaum sab xis, tab sis qhov kub siab yuav tsum tau zam kom tsis txhob muaj cov khoom sib khi los ntawm kev laus.
Txoj kev Actuation:
Los ntawm txhais tes li qub yuav tsum xav txog kev khiav hauj lwm torque (piv txwv li, txuas ntxiv handwheels los yog hnyav) thaum ntsia vertically. Hluav taws xob lossis pneumatic li qub xav tau lub zog ntsuas lub zog los saib xyuas lawv lub xeev kev sib khi kom tiv thaiv lub ntiajteb txawj nqus- vim tias tsav tsheb tsis ua haujlwm.
