Yuav ua li cas tus qauv yuav tsum ua haujlwm ntawm hluav taws xob valve ntsib? Yuav cov cuab yeej hluav taws xob valve yuav tsum tau them sai sai rau qhov teeb meem Hluav taws xob valve fais fab hloov ceev tuaj yeem hloov kho, compact qauv, yooj yim txij nkawm, haum rau kev tswj roj, dej, chav, txhua yam corrosive tshuaj, xuab zeb, roj, kua hlau thiab cov xov tooj cua. thiab lwm hom dej ntws. Lub tshuab hluav taws xob valve yog lub tshuab tseem ceeb los txhawb lub rooj vag valve program tswj, tswj tsis siv neeg thiab tswj chaw taws teeb. Nws lub zog tuaj yeem hloov kho los ntawm kev kho mob stroke, torque lossis radial thrust loj. Vim hais tias cov khoom siv hluav taws xob ua haujlwm thiab kev siv tus nqi yog nyob ntawm qhov hluav taws xob valve fais fab hloov ceev tuaj yeem hloov kho, compact qauv, yooj yim txij nkawm, haum rau kev tswj roj, dej, chav, txhua yam corrosive tshuaj, xuab zeb, roj, kua hlau thiab radioactive tshuaj thiab lwm yam dej ntws. Lub tshuab hluav taws xob valve yog lub tshuab tseem ceeb los txhawb lub rooj vag valve program tswj, tswj tsis siv neeg thiab tswj chaw taws teeb. Nws lub zog tuaj yeem hloov kho los ntawm kev kho mob stroke, torque lossis radial thrust loj. Vim tias cov yam ntxwv ua haujlwm thiab kev siv tus nqi ntawm lub tshuab hluav taws xob valve yog nyob rau hauv hom valve, kev ua haujlwm ntawm cov cuab yeej thiab txoj haujlwm ntawm lub rooj vag valve hauv cov raj xa dej lossis cov khoom siv, kev xaiv kom raug ntawm cov khoom siv hluav taws xob valve yog qhov tseem ceeb tshwj xeeb kom tsis txhob muaj. qhov tshwm sim ntawm overload mob (lub sij hawm ua hauj lwm hloov chaw yog siab tshaj qhov kev khiav hauj lwm torque). Vim tias cov khoom siv hluav taws xob hauv lub tshuab hluav taws xob yog cov cuab yeej siv tshuab, nws qhov xwm txheej ua haujlwm los ntawm qhov chaw ua haujlwm no raug mob loj heev. Feem ntau hais lus, qhov chaw ua haujlwm ib puag ncig uas lub qhov hluav taws xob nyob hauv muaj cov ntsiab lus hauv qab no: 1, nrog cov nplaim hluav taws kub hnyiab, nplaim hluav taws kub hnyiab tau los yog cov pa luam yeeb ib puag ncig; 2. Nyob ib puag ncig ntawm kev sib ntaus sib tua thiab cov chaw nres nkoj tshiab (nrog corrosion kuj, aspergillus flavus, ntub thiab txias); 3. Qhov chaw muaj kev vibration muaj zog; 4. Qhov chaw yooj yim rau kev sib tsoo hluav taws; 5, qhov chaw ntub dej txias, qhov chaw sov huab cua qhuav; 6, pipeline khoom kub siab li 480 ℃; 7. Sab hauv tsev lossis sab nraum zoov daim ntawv thov nrog kev tiv thaiv kev tiv thaiv; 8, sab nraum zoov sib dhos, cua txias, xuab zeb, thaum sawv ntxov dew, tshav corrosion; 9, kev khiav hauj lwm kub yog tsawg dua -20 ℃; 10. Yooj yim rau muab tso rau hauv dej los yog soaked hauv dej; 11. Muaj ib puag ncig ntuj rau cov khoom siv hluav taws xob (nuclear fais fab nroj tsuag thiab cov hluav taws xob hluav taws xob sim kev teeb tsa); Rau cov hluav taws xob valve nyob rau hauv ib puag ncig saum toj no, nws cov khoom siv hluav taws xob, cov khoom siv thiab kev tiv thaiv kev tiv thaiv yog txawv. Yog li ntawd, cov khoom siv hluav taws xob sib txuas yuav tsum raug xaiv raws li qhov chaw ua haujlwm saum toj no. Lub tshuab hluav taws xob valve yog los txhawb lub rooj vag valve kev tswj hwm, kev tswj tsis siv neeg thiab cov chaw taws teeb tswj cov khoom siv lub tshuab tsis tseem ceeb, nws txoj kev txav tuaj yeem hloov kho los ntawm kev mus ncig, torque lossis radial thrust loj. Vim tias cov yam ntxwv ua haujlwm thiab kev siv tus nqi ntawm lub tshuab hluav taws xob valve yog nyob rau hauv hom valve, kev ua haujlwm ntawm lub cuab yeej thiab txoj haujlwm ntawm lub rooj vag valve hauv cov kav dej lossis cov khoom siv, kev xaiv kom raug ntawm lub tshuab hluav taws xob valve yog qhov tseem ceeb tshwj xeeb kom tsis txhob muaj. overload tej yam kev mob (ua hauj lwm torque yog siab tshaj qhov kev khiav hauj lwm torque). Feem ntau, lub hauv paus tseem ceeb rau kev xaiv kom raug ntawm cov khoom siv hluav taws xob valve yog raws li hauv qab no: Kev khiav hauj lwm torque: kev khiav hauj lwm torque yog qhov tseem ceeb tshaj plaws ntawm cov khoom siv hluav taws xob valve. Lub torque muab los ntawm cov khoom siv hluav taws xob yuav tsum yog 1.2 ~ 1.5 npaug ntawm qhov kev ua haujlwm torque ntawm lub rooj vag valve. Kev ua haujlwm tiag tiag thrust: cov qauv tseem ceeb ntawm lub tshuab hluav taws xob valve muaj ob yam: ib qho tsis tau nruab nrog thrust disc, tam sim ntawd xa tawm torque; Lwm qhov yog nruab nrog lub thrust disc thiab lub torque derived yog hloov mus rau derived thrust raws li lub qia txiv ntoo nyob rau hauv lub thrust disc. Tus naj npawb ntawm cov kev hloov pauv ntawm cov tswv yim sib hloov: tus naj npawb ntawm cov kev hloov pauv ntawm cov khoom siv hluav taws xob ntawm lub tshuab hluav taws xob muaj feem cuam tshuam nrog lub npe ntawm lub valve, qhov deb ntawm lub rooj zaum thiab tus naj npawb ntawm cov ntsia hlau. Nws yuav tsum raug xam raws li M = H / ZS (M yog tag nrho cov lem ntawm kev sib hloov uas lub tshuab hluav taws xob yuav tsum tau ntsib, H yog tus txheeb ze qhov siab ntawm lub rooj vag valve qhib, S yog cov ntsia hlau pitch ntawm lub valve lub rooj tsav tsheb, thiab Z yog tus naj npawb ntawm cov ntsia hlau ntawm lub rooj zaum valve). Lub rooj zaum aperture: Multi-rotating qhib-stem rooj vag li qub tsis tuaj yeem ntsia tau raws li hluav taws xob li qub yog tias cov khoom siv hluav taws xob tso cai rau lub rooj zaum loj heev kom tsis haum los ntawm lub qia ntawm lub valve. Yog li ntawd, lub nominal txoj kab uas hla ntawm lub hollow input ncej ntawm lub tshuab hluav taws xob yuav tsum tshaj lub qia txoj kab uas hla ntawm lub qhib pas nrig valve. Rau qee lub rooj vag valve thiab qhib qws rooj vag li qub nyob rau hauv ntau lub rooj vag valve, txawm hais tias tsis tas yuav txhawj xeeb txog qhov teeb meem ntawm lub rooj zaum txoj kab uas hla, lub valve lub rooj aperture thiab groove loj yuav tsum tau coj mus rau hauv tus account hauv kev xaiv ntawm kev sib dhos, thiaj li ua kom muaj kev ua haujlwm zoo tom qab sib dhos. Derived ceev piv: Yog hais tias qhov qhib thiab kaw tus nqi ntawm lub valve yog ceev heev, nws yog ib qho yooj yim los tsim cov dej percussion tshwm sim. Yog li ntawd, yuav tsum ua raws li ntau yam kev thov, xaiv qhov tsim nyog qhib thiab kaw ceev. Valve cov khoom siv hluav taws xob muaj cov kev cai tshwj xeeb uas tuaj yeem txwv torque lossis radial quab yuam. General valve hluav taws xob khoom siv txwv torque coupling. Thaum qhov tshwj xeeb ntawm cov cuab yeej hluav taws xob yog qhov tseeb, nws qhov kev tuav lub zog yuav raug lees paub. Feem ntau nyob rau hauv lub sij hawm ua ntej txiav txim siab, lub cev muaj zog tsis yooj yim rau overload. Tab sis yog tias cov xwm txheej hauv qab no tuaj yeem ua rau overload: thawj zaug, lub zog hluav taws xob tam sim no qis, tsis tuaj yeem tau txais qhov xav tau torque, kom lub cev muaj zog nres; Qhov thib ob, lub zog torque raug kho tsis raug los txwv lub koom haum, kom nws siab tshaj qhov nres torque, uas ua rau tsis tu ncua ua rau lub zog ntau dhau, kom lub cev muaj zog nres; Peb yog daim ntawv thov sib cuam tshuam, qhov tso nyiaj kub, ntau dua li lub cev muaj zog tso cai kom kub nce; Plaub, vim muaj ntau yam, lub zog hluav taws xob hluav taws xob tsis ua haujlwm ntawm lub koom haum torque txwv, kom lub zog torque loj dhau; Thib tsib, qhov kub ntawm kev siv scene yog siab dhau lawm, thiab qhov kev sib raug zoo txo ​​cov thermal conductivity ntawm lub cev muaj zog. Yav dhau los, txoj kev tiv thaiv ntawm lub cev muaj zog yog daim ntawv thov ntawm Circuit Court breaker, tshaj tam sim no solenoid valve, tshav kub relay, kub tswj, tab sis cov txheej txheem no muaj lawv tus kheej zoo. Tsis muaj kev txhim khu kev txhim khu kev qha rau cov tshuab thauj khoom sib txawv xws li cov khoom siv hluav taws xob. Yog li ntawd, ntau yam kev npaj yuav tsum tau ua, tshwj xeeb yog muaj ob lub ntsiab: ib qho yog txiav txim rau kev hloov ntawm lub cev muaj zog input tam sim no; Qhov thib ob yog los txiav txim qhov kub hnyiab ntawm lub cev muaj zog nws tus kheej. Ob txoj kev, tsis hais cov chav kawm twg yuav coj mus rau hauv tus account lub thermal conductivity ntawm lub cev muaj zog rau lub sijhawm muaj peev xwm. Nyob rau hauv dav dav, dab tsi yog qhov yooj yim txij nkawm txoj kev ntawm overload: overload tiv thaiv rau kev ua haujlwm tas mus li lossis pib ua haujlwm ntawm lub cev muaj zog, xaiv qhov ntsuas kub; Rau kev txij nkawm ntawm lub cev muaj zog tig, xaiv cov cua sov relay; Rau luv luv Circuit Court txhaum kev nyab xeeb kev huam yuaj, xaiv Circuit Court breaker los yog tshaj tam sim no solenoid valve.
