Cov khoom siv raw khoom siv yog ib qho khoom siv uas feem ntau siv rau hauv kev teeb tsa cov kav dej, uas yog siv los ntawm kev sib txuas ntawm cov yeeb nkab fittings los txhim kho qhov nruj ntawm cov yeeb nkab txuas. Raw khoom siv yog ib qho tshiab thiab zoo tagnrho sealing khoom. Vim tias nws tsis muaj tshuaj lom, tsis qab, zoo heev sealing, rwb thaiv tsev thiab corrosion kuj, nws yog dav siv nyob rau hauv cov khoom tseem ceeb xws li kev kho dej, natural gas, tshuaj, yas thiab hluav taws xob engineering, tshem tawm cov txawv teb chaws teeb meem ntawm kev sib txuas ntawm raw khoom. siv cov khoom siv; Cua sab hauv raws ntug sab nraud ntawm lub qhov ncauj ntawm cov yeeb nkab.
Ua tib zoo saib rau qhov kev taw qhia winding. Coj lub kaum sab xis valve ua piv txwv. Thaum lub kaum sab xis yog screwed rau hauv xov sab hauv ntawm phab ntsa, nws tig clockwise mus rau sab xis. Tom qab ntawd peb cua cov kab xev seem ntawm lub kaum sab xis ntawm lub kaum sab xis rau sab laug, kom lub kaum sab xis ntawm lub valve yuav nruj dua thiab ntau dua yam tsis muaj loosening. Ua tib zoo saib xyuas qhov flatness ntawm raw khoom siv thaum lub sij hawm winding txheej txheem los xyuas kom meej tias lub qhov ncauj txhob lo lo ntxhuav yog tag qhwv los ntawm raw khoom siv.
Thaum winding, cov khoom siv raw siv yuav tsum nruj kom cov khoom siv raw khoom siv ze rau cov xov. Sim ua kom nruj cov khoom siv raw khoom kom ntau li ntau tau, thiab tsis txhob xoob nws. Tom qab winding, nws yuav tsum nruj ntawm tes hauv lub voj voog lossis tib lub sijhawm. Qhwv rau 2-3 tig, thiab ntug ntawm lo lo ntxhuav lub qhov ncauj yog me ntsis tuab dua li cov khoom siv raw siv hauv lub qhov ncauj lo lo ntxhuav.
Raws li rau winding ntawm "ob peb txheej", tsis muaj ib qho nyuaj thiab ceev kev cai, uas yuav tsum tau screwing thiab tsis muaj to. Txawm li cas los xij, raws li kev paub dhau los, nws feem ntau xav tau ntau tshaj kaum lub voj voog ntawm winding kom ntseeg tau tias cov nyhuv sealing. Tom qab winding, pinch nws nrog ntiv tes nplhaib kom nws haum nrog lub qhov ncauj txhob lo lo ntxhuav.
Thaum ntsia hlau, tsis txhob ntsia hlau rau hauv txoj kev tuag. Nws tsis yog tsim nyog los ntsia hlau rau qhov chaw uas nws tsis tuaj yeem ntsia hlau, tsuav nws pom muaj zog thaum ntsia hlau. Tsis tas li ntawd, xyuam xim rau qhov tob ntawm screwing nyob rau hauv, xws li ob leeg khoov taw ntawm cov dej kub thiab txias sib tov valve. Thaum screwing, ua tib zoo saib xyuas qhov kev ncua deb ntawm phab ntsa, tshwj xeeb tshaj yog thaum ob sab hauv lub luj tshib ntawm phab ntsa tsis nyob rau hauv tib qhov tob. Tuav lub qhwv lub connector thiab ntsia hlau rau hauv qhov chaw clockwise.
