Yas valve yog ib hom kev siv dav dav, nws muaj qhov zoo ntawm corrosion kuj, lub teeb yuag, hnav tsis kam, thiab lwm yam. Nws yog dav siv hauv tshuaj, petrochemical, kev tiv thaiv ib puag ncig thiab lwm yam lag luam.Hauv qab no yog cov keeb kwm kev loj hlob ntawm cov yas li qub.
Nyob rau xyoo 1950, nrog rau kev loj hlob sai ntawm kev lag luam tshuaj, qhov kev thov rau li qub maj mam nce.Lub sijhawm no, cov ntaub ntawv yas tau siv dav hauv kev lag luam, yog li qee tus engineers pib kawm yuav ua li cas siv cov ntaub ntawv yas hauv kev tsim cov li qub.Cov yas yas thaum ntxov tau tsim los siv cov khoom siv polyvinyl chloride (PVC), uas muaj kev tiv thaiv corrosion zoo, tab sis nws cov khoom siv tsis zoo thiab tsuas yog tsim nyog rau qhov tsis tshua muaj siab thiab qhov kub thiab txias ua haujlwm.
Nyob rau xyoo 1960, nrog kev txhim kho txuas ntxiv ntawm plastics technology, polypropylene (PP), polytetrafluoroethylene (PTFE) thiab lwm yam khoom siv tau siv hauv kev tsim cov yas li qub.Cov ntaub ntawv no muaj cov khoom siv kho tshuab zoo dua thiab tiv thaiv corrosion, thiab tuaj yeem hloov mus rau ntau qhov chaw ua haujlwm.
Xyoo 1970, nrog rau kev loj hlob ntawm cov yas valve technology, ntau yam tshiab yas li qub tau qhia, xws li polyvinyl fluoride (PVDF) li qub, iav steel li qub, thiab lwm yam. hloov mus rau qhov xav tau ntau dua qhov chaw ua haujlwm.
Thaum pib ntawm lub xyoo pua 21st, nrog kev paub txog kev tiv thaiv ib puag ncig, cov kev xav tau ntawm cov li qub tau dhau los ua siab dua.Lub sijhawm no, qee cov ntaub ntawv yas tshiab tau siv rau hauv kev tsim cov li qub, xws li polyetherketone (PEEK), polyimide (PI) thiab lwm yam khoom siv yas zoo.Cov ntaub ntawv no muaj cov khoom siv kho tshuab zoo dua thiab kev tiv thaiv corrosion, thiab tuaj yeem ua tau raws li qhov xav tau ntau tshaj qhov chaw ua haujlwm.
Nyob rau hauv luv luv, nrog rau txoj kev loj hlob ntawm cov tshuaj lom neeg kev lag luam thiab kev nruam innovation ntawm plastics technology, yas li qub tau ntsib txoj kev loj hlob ntawm high-kev ua tau zoo yas ntaub ntawv los ntawm cov ntaub ntawv PVC thaum ntxov mus rau tam sim no, tas li txhim kho lawv corrosion kuj, txhua yam khoom thiab thaj tsam ntawm daim ntawv thov, dhau los ua ib qho tseem ceeb thiab indispensable cuab yeej rau tshuaj, petrochemical thiab ib puag ncig tiv thaiv kev lag luam.
