Txhua hnub txij nkawm valve lub ntsiab kev ua tau zoo

Kev tu txhua hnub valve lub ntsiab kev ua haujlwm Txhua hnub txij nkawm 1. Kev saib xyuas yuav tsum tau them rau qhov chaw cia ntawm lub valve. Nws yuav tsum tau muab cia rau hauv ib chav qhuav thiab ventilated thiab thaiv ntawm ob kawg ntawm cov channel. 2, lub valve yuav tsum tau xyuas tsis tu ncua, thiab tshem tawm cov av ntawm nws, smear anti-xeb roj ntawm nws nto. 3. Tom qab kev teeb tsa thiab daim ntawv thov ntawm lub valve, nws yuav tsum tau kho tsis tu ncua kom ntseeg tau tias nws ua haujlwm li qub. 4. Xyuas seb lub sealing nto ntawm lub valve puas hnav thiab kho lossis hloov nws raws li qhov xwm txheej. 5, xyuas cov xov trapezoidal hnav ntawm qia thiab qia txiv ntoo, seb lub ntim khoom puas yog qhov qub thiab tsis siv, thiab ua qhov tsim nyog hloov. 6, lub sealing kev ua tau zoo ntawm lub valve yuav tsum tau kuaj kom paub tseeb tias nws cov kev ua tau zoo. 7. Lub valve hauv kev ua haujlwm yuav tsum tsis zoo, cov bolts ntawm flange thiab bracket ua tiav, cov xov tsis puas, thiab tsis muaj qhov tshwm sim xoob. 8, yog hais tias lub log yog ploj lawm, nws yuav tsum tau npaj txhij nyob rau hauv lub sij hawm, thiab tsis tuaj yeem hloov tau los ntawm ib tug adjustable ciaj ntswj. 9. Packing caj pas tsis raug tso cai rau skewed los yog tsis muaj preload clearance. 10, yog hais tias lub valve siv ib puag ncig phem dua, yooj yim los nag, daus, plua plav, xuab zeb thiab lwm yam paug paug, yuav tsum tau nruab rau lub qia tiv thaiv npog. 11, lub valve ntawm lub teev yuav tsum tau khaws cia kom tiav, meej, meej, valve foob, cap. 12, rwb thaiv tsev tsho yuav tsum tsis txhob sag, tawg. 13, nyob rau hauv kev ua haujlwm ntawm lub valve, tsis txhob khob nws, los yog txhawb nqa cov khoom hnyav, thiab lwm yam. Cov kauj ruam ntawm kev ntxuav lub valve yuav tsum tau ua raws li cov txheej txheem hauv qab no ua ntej sib dhos: 1, raws li cov kev xav tau, qee qhov yuav tsum tau ua polishing, nto tsis tuaj yeem muaj kev ua burr, thiab lwm yam .; 2. Txhua qhov chaw yog degreased; 3, pickling passivation tom qab degreasing, tus neeg saib xyuas tsis muaj phosphorus; 4, pickling purified nrog dej ntshiab tom qab ntxuav, tsis muaj tshuaj residue, carbon steel qhov chaw tshem tawm cov kauj ruam no; 5, ib qho los ntawm ib qhov chaw nrog cov ntaub tsis-woven qhuav, tsis tuaj yeem khaws cov ntaub plaub ntawm qhov chaw, lossis nrog cov nitrogen kom qhuav; 6. So cov khoom ib los ntawm ib qho nrog cov ntaub ntawv uas tsis yog-woven los yog cov ntawv lim dej uas muaj cov cawv ntshiab kom txog thaum tsis muaj xim qias neeg. Lub ntsiab kev ua tau zoo ntawm lub valve valve sealing qhov chaw ntawm lub peev xwm los tiv thaiv kev tshaj tawm tawm, nws yog qhov tseem ceeb tshaj plaws kev ua tau zoo ntawm lub valve. Muaj peb qhov kev sib khi ntawm lub valve: kev sib cuag ntawm qhov qhib thiab kaw qhov chaw thiab lub rooj zaum valve ob lub sealing nto; Packing thiab valve qia thiab packing box txuam; Kev sib koom ntawm lub cev rau lub kaus mom. Ib qho ntawm cov dej xau yav dhau los yog hu ua internal to, uas feem ntau hais tias yog lax, nws yuav cuam tshuam rau lub peev xwm ntawm lub valve kom txiav tawm qhov nruab nrab. Lub ntsiab kev ua tau zoo ntawm valve Ua ntej, valve sealing kev ua tau zoo Xa mus rau lub valve sealing qhov chaw ntawm lub peev xwm los tiv thaiv kev tawm tawm, nws yog qhov tseem ceeb tshaj plaws kev ua tau zoo ntawm lub valve. Muaj peb qhov kev sib khi ntawm lub valve: kev sib cuag ntawm qhov qhib thiab kaw qhov chaw thiab lub rooj zaum valve ob lub sealing nto; Packing thiab valve qia thiab packing box txuam; Kev sib koom ntawm lub cev rau lub kaus mom. Ib qho ntawm cov dej xau yav dhau los yog hu ua kev xau sab hauv, uas feem ntau hais tias yog lax, nws yuav cuam tshuam rau lub peev xwm ntawm lub valve kom txiav tawm qhov nruab nrab. Rau cov chav kawm thaiv valve, sab hauv to tsis tso cai. Ob qhov tom kawg yog hu ua sab nraud to, uas yog, tawm los ntawm lub valve mus rau lub valve sab nraud. Cov dej xau yuav ua rau cov khoom poob, kev ua qias tuaj ib puag ncig, loj heev yuav ua rau muaj xwm txheej. Rau flammable, explosive, tshuaj lom los yog radioactive xov xwm, tsis tso cai, yog li lub valve yuav tsum muaj kev ruaj ntseg sealing kev ua tau zoo. Ob, qhov nruab nrab ntws Qhov nruab nrab yog hais txog qhov nruab nrab los ntawm lub valve yuav ua rau lub siab poob (siab sib txawv ua ntej thiab tom qab lub valve), uas yog, lub valve muaj qee yam tsis kam mus rau qhov nruab nrab ntawm qhov nruab nrab, nruab nrab kom kov yeej qhov tsis kam. ntawm lub valve yuav haus ib tug npaum li cas ntawm lub zog. Los ntawm kev xav txog kev txuag hluav taws xob, tsim thiab tsim cov li qub kom txo tau lub valve tsis kam mus rau qhov nruab nrab ntws kom ntau li ntau tau. Peb, qhib thiab kaw quab yuam thiab qhib thiab kaw lub sijhawm Qhib thiab kaw lub zog thiab lub zog yog lub zog lossis lub zog uas yuav tsum tau siv los qhib lossis kaw lub valve. Kaw lub valve, qhov yuav tsum tau ua rau qhib-kaw ib feem thiab xa ib daim ntawv foob ntawm ob lub sealing nto siab, tab sis kuj kov yeej ntawm qia thiab ntim, lub valve qia thiab nruab nrab ntawm threads ntawm cov txiv ntseej, valve pas nrig kawg bearing kev sib txhuam thiab Lwm qhov chaw ntawm kev sib txhuam quab yuam, thiab yog li ntawd yuav tsum tau siv lub zog kaw thiab kaw lub sijhawm, nyob rau hauv tus txheej txheem ntawm kev qhib thiab kaw, lub valve yuav tsum tau qhib thiab kaw quab yuam thiab qhib-kaw torque hloov, nws qhov siab tshaj plaws tus nqi yog qhov kawg ntawm lub sijhawm kaw lossis thaum pib ntawm lub sijhawm qhib. Valves yuav tsum tau tsim thiab tsim los txo lub zog kaw thiab kaw torque. Plaub, qhib thiab kaw ceev Kev qhib thiab kaw ceev yog qhia raws li lub sijhawm xav tau los ua kom tiav qhov qhib lossis kaw ntawm lub valve. Lub valve qhib thiab kaw ceev tsis yog qhov yuav tsum tau nruj, tab sis qee qhov kev xav tau tshwj xeeb rau kev qhib thiab kaw ceev, xws li qee qhov yuav tsum tau qhib lossis kaw nrawm, thaum muaj xwm txheej, qee qhov yuav tsum tau kaw qeeb, thaum muaj dej tawm tsam, uas yuav tsum tau txiav txim siab thaum xaiv hom valve. Tsib, kev txav rhiab heev thiab kev ntseeg siab Kev ua haujlwm rhiab heev thiab kev ntseeg tau hais txog lub valve rau nruab nrab qhov kev hloov pauv, ua rau cov lus teb sib xws rau qib ntawm rhiab heev. Rau throttle valve, siab txo valve, tswj valve thiab lwm yam li qub siv los kho qhov nruab nrab ntawm qhov nruab nrab thiab kev nyab xeeb valve, ntxiab valve thiab lwm yam li qub nrog cov haujlwm tshwj xeeb, nws qhov kev ua haujlwm siab thiab kev ntseeg siab yog qhov tseem ceeb ntawm kev ua tau zoo. Rau, kev pab cuam lub neej Kev pab cuam lub neej yog hais txog lub durability ntawm lub valve, yog ib qho tseem ceeb Performance index ntawm lub valve, thiab muaj kev lag luam tseem ceeb. Feem ntau hauv kev txiav txim siab kom ntseeg tau tias kev sib khi ntawm cov sijhawm ntawm cov sijhawm los nthuav qhia, tuaj yeem qhia los ntawm kev siv sijhawm.
