Cov nqi hluav taws xob nce siab yuav tsum muaj kev tsim khoom lag luam txhawm rau txhim kho kev tsim khoom, ua ib feem tseem ceeb ntawm kev tsim khoom, tswj li qub tuaj yeem ua tiav thiab tswj kev sib khi zoo ncaj qha cuam tshuam rau kev ua haujlwm ntawm lub Hoobkas. Tswj valve to yog ib qho tseem ceeb Performance index uas tswj valve manufacturers, designers thiab cov neeg siv kev txhawj xeeb txog. Lub to ntawm lub valve tswj tau muab faib ua sab nraud to thiab sab hauv to ob qhov chaw: sab nraud to feem ntau yog hais txog cov to ntawm lub ntim thiab lub valve cover seal ntawm lub valve lub cev; Internal leakage feem ntau yog hais txog kev xau los ntawm kev nkag mus rau qhov tawm ntawm lub valve thaum lub valve raug kaw, rau qhov tsis sib npaug ntawm qhov sib npaug nws yog hais txog kev xau ntawm lub rooj zaum, rau qhov sib npaug ntawm qhov sib npaug nws yog hais txog qhov sib npaug ntawm cov xau ntawm lub rooj zaum thiab cov xau ntawm lub nplhaib foob, tab sis nws feem ntau hu ua lub rooj zaum valve.
Kev xau tuaj yeem tswj tau los ntawm kev xaiv cov ntim khoom tsim nyog, tsim nyog tsim ntawm lub cev lub cev thiab lub valve npog kev sib txuas, cov tuam txhab thiab cov neeg siv tsis tshua xav tau lub Hoobkas kuaj, thiab kev saib xyuas ib puag ncig feem ntau ua tiav ntawm qhov chaw thov. Cov dej ntws sab hauv ntawm lub valve tswj - qhov tso tawm ntawm lub rooj zaum valve yog qhov tseem ceeb ntawm lub Hoobkas tshuaj ntsuam xyuas, thiab tus neeg siv tau nruj me ntsis raws li cov txheej txheem ntawm cov dej ntws tawm ntawm lub rooj zaum valve, yog li nws tseem ceeb heev rau kev kawm thiab txheeb xyuas qhov cuam tshuam. yam ntawm qhov to ntawm lub rooj zaum tswj valve.
Ua rau cov dej ntws tawm ntawm lub cev valve thiab lub kaus mom
- cam khwb cia hlau casting zoo tsis siab, lub valve lub cev thiab lub valve npog lub cev muaj cov xuab zeb qhov, lub koom haum xoob, slag suav nrog thiab lwm yam tsis xws luag.
- hnub khov khov
- vuam tsis zoo, muaj slag suav nrog, tsis yog vuam, kev ntxhov siab tawg thiab lwm yam tsis xws luag
- Lub cam khwb cia hlau valve puas lawm tom qab raug ntaus los ntawm cov khoom hnyav
Txoj kev tu
- txhim kho cov casting zoo, ua ntej installation nruj me ntsis raws li cov kev cai ntawm lub zog kuaj;
- qhov kub ntawm lub valve ntawm {{0}} degree thiab qis dua 0 degree, yuav tsum tau insulated los yog sib tov kub, txwv tsis pub siv lub valve yuav tsum tau muab tshem tawm dej;
- Lub welds ntawm lub valve lub cev thiab lub valve npog tsim los ntawm vuam yuav tsum tau nqa tawm raws li cov txheej txheem vuam cuam tshuam, thiab kev kuaj xyuas qhov tsis zoo thiab lub zog yuav tsum tau ua tom qab vuam;
- Nws yog txwv tsis pub thawb cov khoom hnyav rau ntawm lub valve, thiab nws tsis raug tso cai rau cuam tshuam cov hlau thiab cov hlau tsis muaj hlau nrog ib txhais tes rauj. Lub installation ntawm loj-caliber li qub yuav tsum tau txais kev txhawb nqa.
