Peb yog tus naj npawb ib hauv koj lub inbox thiab muab cov xov xwm tseem ceeb tshaj plaws hauv kev lag luam-ua rau koj ntse dua thiab siab dua hauv kev sib tw ua lag luam uas niaj hnub hloov pauv. Peb yog tus naj npawb ib hauv koj lub inbox thiab muab cov xov xwm tseem ceeb tshaj plaws hauv kev lag luam-ua rau koj ntse dua thiab siab dua hauv kev sib tw ua lag luam uas niaj hnub hloov pauv. Qhov tseeb valves, piping thiab fittings yog qhov tseem ceeb rau kev ua tiav ntawm cov khoom siv hluav taws xob tsim hluav taws xob. Cov khoom siv suav nrog cov khoom siv nrog ntau yam qauv tsim uas tuaj yeem tsim kom muaj kev sib txuas zoo thiab kev sib khi, thiab muaj kev sib txuas zoo dua qub, yog li ua kom muaj kev nyab xeeb ntawm kev ua haujlwm hauv thermal, nuclear thiab lub zog tauj dua tshiab. Cov chaw tsim khoom tau taw qhia tias thaum txhawb nqa nws cov khoom, kev teeb tsa cov nqi qis dua, kev nyab xeeb thiab kev ua haujlwm tau zoo dua qub, thiab kev npaj thiab kev saib xyuas tsis tu ncua raug txo qis. Nov yog qee cov tuam txhab ua lag luam thiab cov kev pabcuam ntawm cov chaw tsim hluav taws xob, cov kav dej thiab fittings. Boldrocchi ua tiav qhov kev sim ua tiav ntawm nws qhov tshiab 7m los ntawm 7m diverter valve rau roj turbines ua ntej xyoo no. Lub diverter valve yog peb-txoj kev valve uas tuaj yeem tso cov pa roj turbine tso pa tawm mus rau qhov chaw los ntawm lub qhov hluav taws xob bypass, lossis mus rau hauv lub tshuab hluav taws xob rov ua kom sov. Lub damper muaj lub peev xwm siab heev thiab tshaj tus qauv ntawm geometric sealing, sealing siab thiab kaw lub sij hawm, thaum txo kev txij nkawm thiab yooj yim rau kev thauj mus los thiab sib dhos. Qhov kev hloov pauv tshiab no tseem tso cai rau kev hloov pauv sai ntawm ib lub voj voog ib zaug mus rau ib lub voj voog ua ke. Nws yog tsim los tiv taus kub txog li 700C (1,300F), kev co thiab roj turbulence, thiab txhim kho cov khoom hnav. Lub diverter yog nruab nrog lub kaw lus cua sealing, uas tuaj yeem ua rau lub sealing degree ntawm cov pa pa sib npaug li 100% (ua tiav sealing). Cov huab cua foob siab yog siab tshaj +500 hli ntawm cov dej kem (mm wc), thiab cov khoom siv thawj cov chaw tsim khoom feem ntau xav tau +50 hli wc. Lub shunt yog nruab nrog hydraulic actuator. Raws li cov neeg siv khoom xav tau, nws lub sijhawm ua haujlwm ib txwm muaj tsawg dua 60 vib nas this, thiab lub sijhawm kaw thaum muaj xwm txheej ceev yog tsawg dua 20 vib nas this. Txawm li cas los xij, lub shunt yog tsim thiab tsim los kom luv lub sijhawm tsav tsheb. Boldrocchi tsim lub splitter kom yooj yim rau kev thauj thiab sib sau ua ke. Lub splitter tuaj yeem ua ntej sib dhos ua ob peb daim, lossis nws tuaj yeem ua tiav thiab xa tuaj (ib feem). Boldrocchi tsim lub splitter kom tau yooj yim ntsia nyob rau hauv ib lub voj voog tso pa chimney es tsis txhob ntawm lub luj tshib uas twb muaj lawm. Boldrocchi, Biassono, Ltalis Spirax Sarco Engineering Co., Ltd. muab cov khoom lag luam thiab cov kev pab cuam rau thermal zog daws. Nws Spira-trol modular tswj valve tau muab tso rau hauv kev siv ntawm lub Hoobkas, tso cai ceev "plug thiab ua si" installation. Spira-trol's modular tsim muaj qhov hloov ceev "clamp-in-place" valve lub rooj, uas txhais tau hais tias nws txoj haujlwm tuaj yeem hloov kho kom hloov pauv cov nroj tsuag yam tsis tas yuav hloov tag nrho lub valve. Tus kheej-aligning nyob rau hauv-situ clamping valve lub rooj kuj yooj yim txij nkawm, yog li tsis muaj cov cuab yeej tshwj xeeb yuav tsum tau, thiab tsis tas yuav tshem lub valve los ntawm cov kav dej. Qhov no tuaj yeem txuag tau ntau tus nqi piv rau cov qauv tsim ib txwm muaj uas feem ntau muaj cov ntsia hlau ruaj khov-hauv lub rooj zaum. Cov ntsia hlau-hauv lub rooj zaum feem ntau daig nyob rau hauv qhov chaw, xav kom lub valve yuav tsum tau disassembled, ua rau cov nroj tsuag ntev downtime. Muab 1/2 nti rau 4 nti hluav taws xob thiab pneumatic Spira-trol valve, mus txog ANSI 150 flange version. Nrog rau kev ua tiav Spira-trol cov khoom lag luam (exandable mus rau 8 ntiv tes) thiab ANSI 600 siab ntau yam, Spirax Sarco tuaj yeem muab cov kev daws teeb meem los ntawm cua sov, qhov cua thiab cua txias rau cov txheej txheem thiab lub zog rau kev thov kev pabcuam. Spirax Sarco, Cheltenham, UK Lub Tuam Txhab Clark Valve tshaj tawm tias nws tus tswv lub rooj vag valve tsim tau txais API 641 ntawv pov thawj, uas yog thawj tswj valve kom tau txais daim ntawv pov thawj kev ua haujlwm qis. API 641 tus qauv siv rau tag nrho cov valve qia sealing cov ntaub ntawv, thiab qhov siab tshaj plaws tso cai tso tawm yog 100 feem ntawm ib lab los ntawm ntim (ppmv). Qhov API xeem tus qauv xav kom lub valve coj 610 lub voj voog nyob rau hauv qhov kub thiab txias hloov pauv los ntsuas qhov kev ua haujlwm emission thaum lub sij hawm ceev lub neej. Fugitive emissions los ntawm ib txwm valve tsim nyob rau hauv industrial chaw yog lub ntsiab ua rau huab cua paug, thiab lub cim tsim ntawm lub qhov rooj li qub muab zoo heev sealing ntawm lub valve qia, yog li txo cov emissions. Lub patented shutter valve tau kuaj nws tus kheej los ntawm Yarmouth Research thiab Technology. Lub valve tau ua pov thawj tias lub valve tau dhau qhov kev sim ntawm tsawg dua 20 ppmv, zoo dua li 100 ppmv txwv. Qhov tshwj xeeb tsim ntawm lub kaw lub valve yog twb yog qhov zoo tshaj plaws kev tswj valve nyob rau hauv lub ntiaj teb no, thiab tam sim no nws tseem yog tus phooj ywg zoo tshaj plaws tswj valve puas tau. Clarke Valve, Miami, Florida Westinghouse tau tshaj tawm nws cov Sigma Reactor Coolant Pump (RCP) cov ntsaws ruaj ruaj, uas yog tsim los ua kom zoo sib xws raws li Westinghouse RCP thawj-tiam foob hloov qhov chaw thiab khoom siv. Nws lub hom phiaj muab kev pabcuam txhim khu kev qha txog li 12 xyoos, uas tuaj yeem txuag nqi, txo cov koob tshuaj thiab txhim kho qhov kev pheej hmoo ntawm cov nroj tsuag nuclear. Sigma cov ntsaws ruaj ruaj tau ua kom zoo kom ua tiav qhov kev ua tau zoo thiab txo qis ib puag ncig rhiab heev, thiab tau txais kev txhawb nqa los ntawm ntau tshaj 20,000 teev ntawm kev txhim kho thiab kev xeem ntawv. Sigma cov ntsaws ruaj ruaj tau ua tiav nrog Westinghouse SHIELD passive thermal shutdown seals. Lub tuam txhab txoj hauv kev muab cov kev daws teeb meem zoo tshaj plaws, raug nqi sealing nrog kev ntseeg tau zoo thiab siv tau ntev, thiab kev sib xyaw ua ke ntawm kev nyab xeeb kev nyab xeeb. Tus tshiab Sigma foob tsim yog raws li ntau tshaj 40 xyoo ntawm kev txhim kho thiab kev khiav hauj lwm cov ntaub ntawv ntawm Westinghouse RCP foob. Westinghouse RCP cov ntsaws ruaj ruaj tau ua tiav tiav rau ntau tshaj 150 lab teev hauv ntau dua 600 RCPs hauv cov tshuab hluav taws xob ua dej siab thoob ntiaj teb. Westinghouse Electric Company, Monroeville, Pennsylvania Everlasting Valve's boiler blowdown valve siv lub tuam txhab patented rotary valve technology, uas muaj kev ua tau zoo heev thiab kav ntev. Cov phau ntawv qhib-tawm li qub no tuaj yeem tso tawm cov sludge tsim hauv chav boiler. Lawv muaj lub kaum sab xis thiab lub kaum sab xis rau kev qhib ceev thiab qhib qeeb, thiab tsim nyog rau kev siv xws li chav boiler blowdown, nto blowdown, dej kem ntws, thiab nres li qub thiab nres li qub. Everlasting's boiler blowdown valve yog raws li ASME boiler thiab siab hlab ntsha ntu 1 code thiab ANSI B16.31 fais fab piping code. Cov li qub no yog tsim los txo cov nqi tu thiab kev poob qis. Lub rooj zaum valve thiab disc tuaj yeem ua los ntawm cov hlau tsis muaj steel, thiab lub valve yog ua los ntawm cov hlau cam khwb cia lossis carbon steel nrog threaded lossis flanged txuas. Lub Valve ntawm Eternity, Sab Qab Teb Plainfield, New Jersey Copes-Vulcan's DSCV-SA (Direct Steam Transfer Valve-Steam Atomization) ntawm SPX FLOW hom ua tau raws li qhov yuav tsum tau ua rau kev ua haujlwm zoo heev thiab muaj lub luag haujlwm kaw nruj heev.
