Lub luag haujlwm ntawm valve lockout
Nyob rau hauv cov ntsiab lus ntawm lockout tagout, valve lockout muaj cov haujlwm hauv qab no:
- Tswj kev nyab xeeb:Kev kaw lub valve tuaj yeem tiv thaiv li qub los ntawm kev ua haujlwm yam tsis muaj kev tso cai lossis ua yuam kev, yog li zam kev xau, khoom siv puas tsuaj, thiab txawm tias muaj kev nyab xeeb tshwm sim los ntawm qhov tsis raug valve qhib lossis kaw.
- Tiv thaiv kev ua haujlwm tsis raug:Hauv kev tsim khoom lag luam, cov li qub yuav tsum tau tswj xyuas thiab kho. Lub kaw lus kaw tuaj yeem kaw lub valve thaum lub sijhawm cov txheej txheem no los tiv thaiv kev sib tsoo los ntawm kev tsis saib xyuas lossis kev ua haujlwm tsis raug.
- Cov nyhuv ceeb toom:Lub valve kaw thiab tagging tuaj yeem ceeb toom rau lwm tus neeg ua haujlwm kom xyuam xim tias lub valve raug kaw thiab tsis tuaj yeem txav mus los lossis ua haujlwm ntawm lub siab nyiam, ua haujlwm ceeb toom.
- Kev ruaj ntseg cov khoom siv:Los ntawm kev kaw lub li qub, nws tuaj yeem ua kom ntseeg tau tias cov cuab yeej kaw kiag li thiab tseem nyob hauv lub xeev muaj kev nyab xeeb, tiv thaiv cov khoom siv los ntawm kev pib yuam kev, ua rau raug mob lossis tuag taus.
Cov khoom siv feem ntau siv rau kev kaw lub valve thiab cov laj thawj rau lawv xaiv yog raws li hauv qab no:
- Nylon:Nws muaj kev cuam tshuam zoo thiab tshuaj lom neeg ruaj khov, yog corrosion-resistant, thiab tuaj yeem tswj tau qhov kev ua tau zoo nyob rau hauv ib puag ncig hnyav.
- ABS engineering yas:Nws muaj lub zog siab, muaj kev cuam tshuam zoo, thiab tuaj yeem ua rau ntau yam duab los hloov mus rau ntau hom valve.
- Polypropylene:Nws muaj kev cuam tshuam zoo, tiv taus tshuaj lom neeg corrosion, thiab ruaj khov thiab ruaj khov.
- Polytetrafluoroethylene:Nws muaj kev tiv thaiv corrosion zoo heev thiab hnav tsis kam, thiab feem ntau yog siv los ua lub rooj zaum valve lossis diaphragm nto khoom ntawm li qub.
- Industrial-qib steel: Nws muaj lub zog siab thiab ua haujlwm ntev, tsim nyog rau feem ntau thaj chaw muaj kev lag luam, thiab tuaj yeem tiv thaiv sab nraud los ntawm kev puas tsuaj.
- Stainless hlau:Nws muaj zog corrosion kuj thiab haum rau siab - kub, siab - av noo los yog ib puag ncig nrog tshuaj corrosion. Piv txwv li, austenitic stainless hlau, tshwj xeeb stainless hlau, thiab lwm yam, yog haum rau txawv corrosive media.
