Txhawm rau xaiv txoj cai tawg-ntawv pov thawj pneumatic pob valve yuav tsum txiav txim siab tau txiav txim siab:
1.} cov khoom nruab nrab
Tshuaj lom corrosiveness: Yog hais tias lub corrosed yog heev corrosive, xws li muaj cov tshuaj muaj zog xws li} nws muaj cov kuab tshuaj zoo, thiab cov kuab tshuaj muaj zog.} rau qee qhov tsis muaj zog Cov xov xwm corrosive, xws li cov kev daws teeb meem hauv qab, xws li ethylene propylene diene monomer (EPDM), tseem tuaj yeem ua tau raws li qhov yuav tsum tau.
Nruab Nrab Kub: Kev Kub Ntxov Ntxov muaj cov khoom siv hluav taws xob ntau dua kev sib tw hauv cov teebmeem .
Kev nyiam huv ntawm nruab nrab: yog tias nruab nrab muaj qhov cuam tshuam tsis zoo, thiab muaj peev xwm tiv taus cov kev yaig-sandy thiab hnav ntawm cov lus {{2}
2.} ua haujlwm siab ua haujlwm
Cov roj av qis dua
Nruab nrab- thiab cov kev ntsuas siab: thaum ua haujlwm siab yog {}}}}}} Cov khoom siv tau zoo dua li 10 MPa, cov xov hlau ntau dua yuav tau siv, xws li ntsaws ruaj ruaj ua los ntawm cov hlau tsis muaj hlau, tooj liab, thiab lwm yam ., uas muaj lub zog siab dua thiab siab tsis muaj zog.
3. tus nqi siv
Nyob rau hauv lub koob npe ntawm kev siv cov ntaub ntawv uas yuav tsum tau ua, xws li siv cov khoom siv tshwj xeeb thiab feem ntau xav tau kev ua tau zoo thiab tsis tshua muaj neeg xav tau kev ua tau zoo thiab tsis tshua muaj kev ua haujlwm thiab tsis tshua muaj ib puag ncig {{5 5}
