Cov yam ntxwv ntawm cov khoom
1. Qhov cua npauj npaim valve yog qhov tshiab thiab tsim nyog hauv kev tsim, tshwj xeeb hauv cov qauv, lub teeb hauv qhov hnyav thiab ceev hauv kev qhib thiab kaw.
2. Lub npauj npaim valve muaj qhov zoo ntawm lub sijhawm ua haujlwm me me, kev ua haujlwm yooj yim thiab ntse ua haujlwm-txuag.
3. Siv cov ntaub ntawv tsim nyog kom tau raws li qhov sib txawv ntawm qhov sib txawv ntawm qhov qis, nruab nrab thiab siab tshaj tawm thiab corrosive media.
4. Tsis muaj kev sib txuas cov pas nrig, bolts, thiab lwm yam, txhim khu kev qha kev ua haujlwm, kev pab lub neej ntev, tsis cuam tshuam los ntawm kev khiav dej num ntawm kev tshaj tawm.
