Cov Ua Rau Lub Rooj Zaum Tsis Ua Haujlwm thiab Cov Lus Qhia Txog Kev Txhim Kho Cov Qauv

Tom qab ua cov haujlwm valve tau ntau xyoo no, qhov tseeb, kuv tau pom ntau qhov teeb meem ntawm lub rooj zaum valve. Feem ntau, tus neeg siv yws txog qhov xau ntawm lub valve, qhov tseeb, tsis yog teeb meem ntawm lub spool, tab sis lub rooj zaum valve tau hnav ntev lawm. Qee zaum nws yog cov khoom siv tsis zoo, qee zaum nws yog cov qauv ntawm tus qauv tsis xav txog cov xwm txheej ua haujlwm.

Peb tau teeb tsa lub pob valve hauv lub Hoobkas coking ua ntej, cov xov xwm muaj hmoov av, kub siab, cov duab kos duab sau rau ntawm lub rooj zaum mos mos stainless hlau, cov txiaj ntsig ntawm tsawg dua ib nrab xyoo ntawm kev ua haujlwm, rov qab mus ntsib pom tias muaj ntau chav tsev ntawm kev xau sab hauv loj. Disassembled thiab pom tias lub nplhaib sealing khawb, ntug ntawm lub rooj zaum valve kuj me ntsis vau. Tom qab ntawd hloov nrog lub rooj zaum hlau welded nyuaj, lub neej ntev dua ntau dua ob xyoos.

Muaj ntau hom kev ua tsis tiav uas feem ntau tshwm sim: ib qho yog qhov hnav ntawm qhov chaw sib khi, tshwj xeeb tshaj yog nrog cov khoom khov kho, qhov qhib thiab kaw ntau zaus hauv qab qhov khawb sai heev; qhov thib ob yog qhov txheej vuam tev tawm, uas feem ntau yog cov txheej txheem ntawm qhov chaw tsis nyob hauv qhov chaw lossis kev ntxhov siab ntawm kev kho cua sov tsis raug tso tawm; kuj tseem muaj teeb meem zais cia yog lub spool thiab lub rooj sib dhos tsis sib xws, qhov tshwm sim yog tias ib sab ntawm cov leeg qub, ib sab ntawm qhov xau.

Yog tias theem tsim tsis coj lub rooj zaum valve tiag tiag, teeb meem yuav luag tsis zam. Peb muaj ib tus neeg siv khoom hauv kab tsim khoom alumina nrog ntau lub V-ball valves, lub rooj zaum valve yog cov hlau tsis xeb, khiav tsawg dua ib xyoos ntawm kev sib tsoo, kev ntxuav tsis tuaj yeem ntxuav tawm. Tom qab ntawd, peb tau muab lawv ib qho version ntawm taper los txhawb cov qauv, ntxiv qhov txwv bevelled thiab sab hauv kev txhawb nqa groove, khiav tau ob xyoos yam tsis muaj kev puas tsuaj loj.

Nyob rau hauv kev tsim qauv, nws raug pom zoo kom xav txog peb lub ntsiab lus: Ua ntej, qhov chaw sib khi ntau li ntau tau kom hloov tau, tawm ntawm qhov teeb meem tuaj yeem kho tau ntawm qhov chaw; Qhov thib ob, cov khoom siv tuaj yeem sib dhos vuam rau ntawm qhov tsis xav txuag teeb meem nrog ib qho hlau tsis xeb; Qhov thib peb, qhov sib dhos ntxiv rau qhov chaw nruab nrab, tsis txhob cia siab rau kev sib dhos tes kom tau ua ke. Txwv tsis pub, qhov kev teeb tsa me ntsis, hloov ob peb puas zaug tom qab pib ntawm 'gnawing spool'.

Hauv cov qauv ntawm lub rooj zaum valve uas peb tau ua, zoo li kev sib xyaw ua ke ntawm cov hlau bevelled txwv + composite sealing insert, qhov kev ua tau zoo ruaj khov heev hauv cov xwm txheej ua haujlwm ntawm cov roj thee, ammonium phosphate, cov kua dej ntsev ntau. Tam sim no ntau tus neeg siv khoom tau koom nrog peb cov qauv tshwj xeeb rau hauv lawv cov pob khoom siv, uas qhia tau tias hom kev daws teeb meem no tuaj yeem daws cov teeb meem hauv daim teb.

Lub rooj zaum valve yog ib yam dab tsi uas tsis muaj leej twg them sai sai thaum tsim qauv, thiab yog tias muaj qee yam tsis raug, nws yog ib qho teeb meem loj. Xav kom txhua tus tsim qauv, ua cov neeg sib tw yuav khoom, tsis txhob tsuas yog saib daim ntawv qhia xwb, mloog cov neeg ua haujlwm hauv thaj chaw thiab kev saib xyuas yuav hais li cas. Vim tias cov xwm txheej ua haujlwm yeej tsis tos tib neeg, cov qauv zoo, teeb tsa peb lub hlis kom paub.
