- nruab nrab: pob li qub hauv kev siv yuav tsum tau xyuam xim rau kev siv nruab nrab kom ua tau raws li qhov kev xaiv tam sim no ntawm lub pob valve, xws li kev siv nruab nrab rau cov roj, feem ntau pom zoo kom siv lub foob mos, yog tias nws yog Cov kua yuav tsum tau ua raws li hom kua, xaiv cov tawv tawv los yog muag muag, yog tias cov kua corrosive yuav tsum tau muab cov fluorine los yog cov khoom tiv thaiv corrosion.
- qhov kub thiab txias: pob li qub hauv kev siv yuav tsum tau them sai sai rau qhov kub ntawm qhov nruab nrab nws ua haujlwm kom tau raws li qhov kev xaiv ntawm lub pob valve tam sim no, xws li kev siv qhov kub siab tshaj 180 degrees yuav tsum tau xaiv cov khoom siv tawv tawv, lossis PPL cov ntaub ntawv kub, xws li ntau tshaj 350 degrees yuav tsum tau txiav txim siab es tsis txhob kub siab resistant cov ntaub ntawv.
- siab: pob li qub hauv kev siv ntau tshaj plaws yog qhov teeb meem siab, feem ntau peb pom zoo tias cov qib siab yuav tsum tau xaiv nrog qib loj, xws li kev siv lub siab ntawm 1.5MPa, peb xav kom peb tsis txhob xaiv 1.6MPa qib, tab sis nrog 2.5MPa, kom lub siab loj hauv cov txheej txheem siv los xyuas kom meej qhov kev nyab xeeb ntawm cov kav dej.
- hnav thiab tsim kua muag: Nyob rau hauv tus txheej txheem ntawm kev siv, peb yuav pom hais tias ib co ntawm qhov chaw ntawm industrial thiab mining yuav tsum tau kuj siab, xws li xov xwm uas muaj ib tug nyuaj hais, xuab zeb, gravel, slurry slag, txiv qaub thiab lwm yam xov xwm, peb feem ntau pom zoo kom siv. ntawm ceramic seals, xws li ceramic seals tsis tuaj yeem daws tau yuav tsum tau txiav txim siab xaiv lwm yam li qub.
