PTFE (Polytetrafluoroethylene) lined npauj npaim li qub feem ntau siv nyob rau hauv ntau yam lag luam rau lawv cov tshuaj tiv thaiv zoo heev thiab kav ntev. Txhawm rau kom muaj kev nyab xeeb thiab ua haujlwm tau zoo, nws yog qhov tseem ceeb uas yuav tsum tau ceev faj tshwj xeeb thaum siv cov li qub no. Nov yog qee qhov kev ceev faj tseem ceeb los xav txog:
Khoom Compatibility: Xyuas kom meej tias cov ntaub ntawv raug ua tiav nrog PTFE hauv ob sab phlu. PTFE yog cov tshuaj tiv thaiv rau feem ntau cov tshuaj, tab sis nws yuav tsis haum rau qee yam tshuaj phem heev.
Kub txwv: Yuav tsum paub txog qhov ntsuas kub ntawm PTFE hauv ob sab phlu. PTFE tuaj yeem tiv taus ntau qhov kub thiab txias, tab sis tshaj nws cov kev txwv tuaj yeem ua rau degradation lossis tsis ua haujlwm.
Kev ntsuas siab: Xyuas kom meej tias lub valve raug ntsuas rau kev khiav hauj lwm siab ntawm koj lub cev. Tshaj-pressurizing tuaj yeem ua rau muaj kev puas tsuaj rau PTFE hauv ob sab phlu lossis lub valve nws tus kheej.
Txhim kho kom raug: Txhim kho lub valve kom raug raws li cov chaw tsim khoom cov lus qhia. Kev teeb tsa tsis raug tuaj yeem ua rau cov dej xau, txo qis kev ua haujlwm, lossis kev puas tsuaj rau hauv ob sab phlu.
Tsis txhob dhau-tightening: Tsis txhob nruj bolts thaum lub sijhawm teeb tsa, vim qhov no tuaj yeem ua rau lub PTFE hauv ob sab phlu lossis distort lub valve lub cev.
Kev tshuaj xyuas tsis tu ncua: Ua cov kev tshuaj xyuas niaj hnub los xyuas cov cim ntawm kev hnav, kev puas tsuaj, lossis kev xeb. Hloov cov khoom puas los yog hnav tam sim ntawd kom tiv thaiv kom tsis txhob muaj dej los yog ua tsis tiav.
Kev xaiv Gasket kom raug: Xaiv cov gaskets tsim nyog rau kev sib khi sib txuas. Xyuas kom meej tias lawv tau sib xws nrog cov tshuaj uas raug tuav thiab sib haum nrog PTFE.
Tsim nyog Torque: Siv lub torque ciaj ntswj kom nruj bolts rau cov chaw tsim khoom pom zoo torque specifications. Over-tightening tuaj yeem ua rau lub hauv ob sab phlu, thaum kev nruj nruj tuaj yeem ua rau cov xau.
Zam kev nyuaj siab: Tiv thaiv kom tsis txhob muaj kev ntxhov siab ntau dhau ntawm lub valve, xws li kev cuam tshuam lossis kev khoov, uas tuaj yeem ua rau PTFE hauv ob sab phlu.
Kev tu thiab lubrication: Ua raws li lub sijhawm saib xyuas tau pom zoo los ntawm cov chaw tsim khoom. Lubricate txav qhov chaw raws li xav tau los xyuas kom meej kev ua haujlwm zoo.
Tsis txhob Abrasive Media: PTFE yog qhov yooj yim rau cov ntaub ntawv abrasive. Tsis txhob siv PTFE kab npauj npaim li qub hauv cov ntawv thov uas cov xov xwm muaj cov khoom abrasive uas tuaj yeem hnav hauv ob sab phlu.
Kev ntsuas kev nyab xeeb: Siv cov kev ntsuas kev nyab xeeb hauv koj qhov chaw, xws li cov txheej txheem kaw thaum muaj xwm txheej ceev thiab cov txheej txheem tswj hwm, txhawm rau txo cov kev pheej hmoo cuam tshuam nrog lub valve tsis ua haujlwm.
Kev cob qhia: Xyuas kom cov neeg ua haujlwm ua haujlwm thiab tswj cov valve no tau raug cob qhia kom raug thiab paub txog kev ceev faj thiab kev ntsuas kev nyab xeeb uas yuav tsum tau siv rau lawv.
Teb ceev xwm ceev: Muaj ib txoj kev npaj rau kev teb rau lub valve tsis ua hauj lwm los yog xau, nrog rau kev siv cov cuab yeej tiv thaiv tus kheej tsim nyog thiab cov txheej txheem kaw thaum muaj xwm ceev.
Kev sim: Ib ntus sim lub valve qhov kev ua tau zoo thiab kev ncaj ncees txhawm rau txheeb xyuas cov teeb meem ua ntej lawv tseem ceeb.
Nco ntsoov xa mus rau cov chaw tsim khoom cov lus qhia thiab cov lus pom zoo tshwj xeeb rau koj lub PTFE kab npauj npaim valve kom ua haujlwm kom raug thiab kev nyab xeeb. Ua raws li cov kev ceev faj no yuav pab koj tswj kom muaj kev ncaj ncees thiab kev ntseeg siab ntawm koj PTFE kab npauj npaim li qub hauv koj cov txheej txheem kev lag luam.
