Kev ceev faj rau kev txhim kho Steel Gate Valve
Lub tes log, kov thiab kis tau tus mob mechanism tsis pub siv rau kev nqa, thiab kev sib tsoo yog nruj me ntsis txwv.
Ob chav rooj vag li qub yuav tsum tau nruab vertically (piv txwv li lub valve qia yog nyob rau hauv txoj hauj lwm ntsug thiab lub tes log yog nyob rau saum).
Lub rooj vag valve nrog bypass valve yuav tsum qhib lub viav vias valve ua ntej qhib (kom sib npaug ntawm qhov sib txawv ntawm qhov nkag thiab qhov hluav taws xob thiab txo qhov qhib quab yuam).
Lub rooj vag valve nrog kis tau tus mob yuav tsum tau ntsia raws li cov kev cai ntawm cov khoom lag luam phau ntawv.5. Yog tias lub valve feem ntau qhib thiab kaw, lubricate nws tsawg kawg ib hlis ib zaug.
