Cov teeb meem ntawm Internal leakage ntawm Safety Valve feem ntau tshwm sim. Yuav daws li cas
Feb 12, 2022
Kev nyab xeeb valve yog ib qho khoom siv tiv thaiv overpressure. Thaum lub siab nyob rau hauv cov khoom siv, lub thawv lossis cov raj xa dej ntau tshaj qhov kev tso cai, lub valve yuav cia li qhib thiab tom qab ntawd tso tawm tag nrho, txhawm rau tiv thaiv lub siab ntawm cov khoom siv, lub thawv lossis cov kav dej tsis tu ncua; Thaum lub siab poob mus rau tus nqi teev tseg, lub valve yuav kaw cia rau hauv lub sijhawm los tiv thaiv kev nyab xeeb ntawm cov khoom siv, cov hlab ntsha lossis cov kav dej.
Tam sim no, kev nyab xeeb li qub feem ntau yog siv hauv boilers, cov hlab ntsha siab thiab cov kav dej, uas ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv tus kheej kev nyab xeeb thiab cov khoom siv ua haujlwm. Lawv tau siv dav hauv kev lag luam tshuaj thiab lwm yam lag luam. Nws tau nkag siab tias txij li xyoo 2013, kev lag luam nplai ntawm Tuam Tshoj txoj kev nyab xeeb valve kev lag luam tau maj mam nthuav dav, tus naj npawb ntawm cov tuam txhab tsim nyog los tsim kev nyab xeeb li qub tau pib nce ntxiv, thiab qhov sib koom ntawm cov khoom lag luam hauv kev lag luam tau maj mam txo, thiab domestic li qub tau maj mam nce. Nyob rau hauv tag nrho, txoj kev loj hlob qhov chaw ntawm domestic kev nyab xeeb li qub nyob rau hauv lub neej yav tom ntej yog dav heev.
Rau cov neeg siv, xaiv qhov kev nyab xeeb valve tsim los ntawm cov tuam txhab tsis tu ncua, txhim kho kom raug thiab ua haujlwm tsim nyog yog qhov chaw ua haujlwm kom ntseeg tau tias nws txoj haujlwm ruaj khov. Txawm li cas los xij, nyob rau hauv tus txheej txheem ntawm kev siv lub valve kev ruaj ntseg, qhov teeb meem ntawm dhia sab hauv to taub feem ntau tshwm sim, yog li yuav ua li cas thiaj nrhiav tau qhov laj thawj thiab daws nws? Kev lag luam tau muab peb cov lus qhia rau kev siv.
Ua ntej, muaj cov xau hauv kev nyab xeeb valve. Kev lag luam tau hais tias thaum muaj qhov xau me me ntawm qhov kev nyab xeeb valve, feem ntau nws nyuaj rau nrhiav, tab sis txawm tias qhov me me to taub yuav nthuav dav thiab erode nyob rau hauv. Nyob rau hauv lub ntsej muag ntawm qhov teeb meem no, cov neeg siv yuav tsum tau xyuas cov kev ruaj ntseg valve.
Txoj kev kuaj xyuas yog ntsuas lub siab, kaw qhov saum npoo ntawm lub foob hauv qhov kev sim, cov dej npog lub hau, saib seb lub siab puas yog npuas. Kev lag luam taw qhia tias "cov txheej txheem kev nyab xeeb valve tau teev tseg tias cov foob mos yuav tsum tsis muaj npuas, thiab lub foob tawv tawv yuav muaj, tab sis cov txheej txheem ntawm cov npuas yuav tsum nyob rau hauv ib qho kev sib tw. Qhov no yuav tsum tau ua tom qab lub calibration. ua tiav, vim tias qhov kev nyab xeeb valve tuaj yeem ua rau lub sealing nto thaum lub sij hawm calibration txheej txheem. "
Qhov thib ob, lub caij nplooj ntoos hlav ua rau qaug zog. Nws tau nkag siab tias lub caij nplooj ntoos hlav muaj kev cuam tshuam zoo heev los ntawm qhov kub thiab ib puag ncig (yog tias qhov kev nyab xeeb valve raug kaw, qhov cuam tshuam ntawm nruab nrab yuav tsum tau txiav txim siab). Yog vim li no, kev xaiv lossis qhov zoo ntawm kev nyab xeeb valve yuav tsum tau txiav txim siab. Qhov no tseem xav kom cov neeg siv xav txog seb qhov kev xaiv ntawm kev nyab xeeb valve puas tsim nyog thiab seb qhov zoo puas tsim nyog thaum xaiv qhov kev nyab xeeb valve.
Thib peb, cov khoom siv kav dej. Piv txwv li, kev vibration thiab kev cuam tshuam ua rau muaj kev kub ntxhov ntau dhau ntawm qhov kev nyab xeeb valve, thiab lub valve tub ntxhais tau sib cais los ntawm kev sib khi ntawm lub rooj zaum valve, ua rau muaj kev puas tsuaj, slag suav nrog, thiab lwm yam.
Kev lag luam tau hais tias, qhov tseeb, kev tsim khoom ntawm kev nyab xeeb valve yog qhov siab heev. Vim hais tias lub sealing quab yuam ntawm kev ruaj ntseg valve yog sib npaug rau lub caij nplooj ntoos hlav quab yuam - nruab nrab siab, uas yog nyob ze rau qhov kev ruaj ntseg valve nyob rau hauv ib qho chaw, xws li lub ntsiab chav, pub dej siab thiab ua hauj lwm siab ntawm lub hwj chim nroj tsuag, qhov tseeb sealing quab yuam. ntawm qhov sealing nto tsis loj heev. Nyob rau hauv qhov kev txiav txim ntawm qis, peb cia siab tias yuav muaj lub foob zoo. Kev ua tiav ntawm qhov sealing nto yuav tsum siab heev, thiab cov khoom muaj qhov xav tau siab.
Plaub, kev ua haujlwm ntawm lub caij nplooj ntoos hlav tsis ruaj khov. Kev lag luam ntseeg hais tias lub caij nplooj ntoos hlav kev ua tau zoo ntawm kev ruaj ntseg valve yuav tsum ruaj khov heev, vim hais tias qhov nruab nrab kub kub yuav txo tau cov zis ntawm lub caij nplooj ntoos hlav, uas yuav ua rau kom nruj ntawm lub foob. Hauv tshwj xeeb, qhov chaw ruaj ntseg valve muaj lub phaj rov qab. Feem ntau, cov dej xau tuaj yeem ua rau dhia ntawm qhov kev nyab xeeb valve, yog li cuam tshuam rau cov khoom siv hluav taws xob.
Tsis tas li ntawd, kev lag luam pom zoo kom tsis txhob ua kev tu tus kheej. Lub valve kev nyab xeeb yog ib qho tseem ceeb los xyuas kom meej tias kev ua haujlwm ruaj ntseg ntawm cov khoom siv. Tsuas yog cov chaw soj ntsuam uas tsim nyog tuaj yeem tshawb xyuas thiab tswj xyuas qhov kev nyab xeeb valve. Nws raug nquahu kom disassemble ib xyoos ib zaug thiab xa tuaj rau kev kuaj xyuas.
