Umsonto wangaphandle wokunciphisa ivalve yebhola yobhedu luhlobo lwevalve ngokubanzi esetyenziswa ngokubanzi kwivalve.
Ukwenza umsonto wangaphandle wokunciphisa ivalve yebhola yobhedu uzinzile ekusebenzeni kwaye ixesha elide kubomi benkonzo, ezi zinto zilandelayo kufuneka ziqwalaselwe:
1. Phambi kokusetyenziswa, sebenzisa amanzi ukucoca umbhobho kunye nenxalenye yomzimba wevalvu ephuphumayo ukuthintela iifayili zentsimbi ezishiyekileyo kunye nobunye ubugoxo ukuba bungene kumngxuma wevalve yebhola.
2. Xa umsonto wangaphandle wokunciphisa ivalve yebhola yobhedu ivaliwe, kusekho i-residual medium kumzimba wevalve, kwaye ithwala uxinzelelo oluthile.Ngaphambi kokuba ulungise ivalve yebhola, vala ivalve yokuvala phambi kwevalve yebhola, vula ivalve yebhola ekufuneka igqitywe, kwaye ukhulule ngokupheleleyo uxinzelelo lwangaphakathi lomzimba wevalvu.
3. Ngokubanzi, i-PTFE isetyenziswa njengesixhobo sokutywina kwiivalvu zebhola ezitywiniweyo ezithambileyo, kwaye indawo yokutywina yeevalvu zebhola etywiniweyo yenziwe ngentsimbi engaphezulu.Ukuba ivalve yebhola yombhobho ifuna ukucocwa, kuyimfuneko ukuba uqaphele ukukhusela umsesane wokutywina kunye nokuvuza ngexesha lokuqhawula.
4. Xa udibanisa kwaye udibanisa i-valve yebhola ye-flanged, iibhotshi kunye namantongomane kwi-flange kufuneka zilungiswe kuqala, ngoko ke zonke iinqununu kufuneka ziqiniswe kancane, kwaye ekugqibeleni ziqiniswe ngokuqinileyo.Ukuba i-nut yomntu iqiniswe ngenkani kuqala, kwaye ke ezinye iinati zilungisiwe, i-gasket surface iya konakaliswa okanye igqabhuke ngenxa ye-uniform lining phakathi kweendawo ze-flange, okubangelwa ukuvuza kwe-medium kwi-valve flange.
