Iivalvu zesango le-Wellhead yinxalenye ebalulekileyo yeenkqubo zokuvelisa i-oyile negesi, zidlala indima ebalulekileyo ekulawuleni ukuhamba kwamanzi equleni.Ezi zivalo zenzelwe ukujamelana noxinzelelo oluphezulu kunye neemeko eziphezulu zokushisa, okwenza ukuba zibaluleke kakhulu ekusebenzeni okukhuselekileyo nokusebenzayo kweentloko zemithombo.Kweli nqaku, siza kuphonononga injongo yevalve yesango le-wellhead kwaye sixoxe ngezona zinto zithambisayo kwiivalvu zesango ukuqinisekisa ukusebenza kwazo ngokupheleleyo.
Injongo yeWellhead Gate Valve
Eyona njongo iphambili aivelufa yesango lomthombokukulawula ukuhamba kolwelo olufana neoli, igesi, namanzi aphuma equleni.Ezi zivalo zifakwe kwi-wellhead, apho zisebenza njengomqobo wokulawula ukuhamba kwee-hydrocarbons kunye nezinye izinto ezikhutshwe kwi-reservoir.Ngokuvula okanye ukuvala i-valve, abaqhubi banokuvumela ukuhamba kwamanzi okanye bavale ngokupheleleyo, banikeze indlela yokulawula inkqubo yokuvelisa.
Ukongeza kulawulo lokuhamba, iivalve zesango le-wellhead nazo zidlala indima ebalulekileyo ekukhuseleni kakuhle.Kwimeko engxamisekileyo, njengokuvuthela okanye ukukhutshwa okungalawulwayo kwamanzi, i-valve yesango inokuvalwa ngokukhawuleza ukuze ihlukanise iqula kwaye ithintele ukunyuka okuqhubekayo kwimeko.Esi sikhundla siyimfuneko ekukhuseleni abasebenzi, izixhobo, kunye nokusingqongileyo kwiingozi ezinokubakho ezinxulumene nokusebenza kwentloko yentloko.
Eyona Lubricant yeSango Iivalvu
Ukuthambisa okufanelekileyo kubalulekile ekugcineni ukusebenza kunye nokuphila ixesha elide kweevalvu zesango, kubandakanywa nezo zisetyenziselwa ukusetyenziswa kwe-wellhead.Ukukhethwa kwe-lubricant kunokuchaphazela kakhulu ukusebenza kwevalve, ngakumbi kwiimeko ezinzima zokusebenza ezihlala zidibana kwishishini leoli kunye negesi.Xa ukhetha i-lubricant yeevalvu zesango, izinto ezininzi kufuneka ziqwalaselwe, kubandakanywa ubushushu, uxinzelelo, kunye nokuhambelana nezixhobo zevalve.
Enye yezona zinto zibalaseleyo zokuthambisaiivalve zesangoludidi oluphezulu, igrisi eyenziweyo eyenzelwe ngokukodwa usetyenziso lwevalvu.Iigrisi zokwenziwa zinika ukusebenza okuphezulu kumaqondo obushushu agqithisileyo kwaye zibonelela ngokugqwesa ukuxhathisa kwi-oxidation kunye nokuthotywa, ukuqinisekisa ukusebenza kakuhle kokuthambisa ixesha elide.Ezi grisi zikwabonelela ngokhuseleko olwandisiweyo kumhlwa kunye nokuguga, nto leyo ibaluleke kakhulu kwizivalo zesango ezivezwe kwindawo esebenza nzima.
Ukongeza kwiigrisi zokwenziwa, ezinye iivalve zesango zinokuzuza ekusebenziseni i-lubricant yefilimu eyomileyo, ebonelela ngengubo encinci, ekhuselayo enciphisa ukungqubana kunye nokugqoka.I-lubricant yefilimu eyomileyo ifaneleke ngokukodwa kwiivalvu ezisebenza kwiqondo lokushisa eliphezulu okanye kwiimeko zoxinzelelo oluphezulu, apho iigrisi eziqhelekileyo zingenako ukusebenza.Ngokwenza umaleko ohlala ixesha elide, ophantsi kwe-friction kumacandelo e-valve, i-lubricant yefilimu eyomileyo inokunceda ukuphucula ukusebenza kwevalve kunye nokuthembeka.
Kubalulekile ukuqaphela ukuba ukukhethwa kweyona lubricant ingcono kakhuluivalve yesangokufuneka isekelwe kwiingcebiso zomenzi kunye neendlela ezingcono zoshishino.Ukusetyenziswa ngokufanelekileyo kunye nokugcinwa kwe-lubricant ekhethiweyo nako kubalulekile ukuqinisekisa ukusebenza kakuhle kwevalve kunye nokuphila ixesha elide.Ukuhlolwa rhoqo kunye nokugcotywa kwakhona kweevalvu zesango kufuneka kuqhutywe njengenxalenye yenkqubo yolondolozo olubanzi ukuthintela imiba efana nokuncamathela kwevalve okanye ukuguga ngokugqithisileyo.
Ukuqukumbela
Iivalvu zesango le-Wellhead ziyinxalenye ebalulekileyo yeenkqubo zokuvelisa ioli kunye negesi, ezikhonza iinjongo ezimbini zokulawula ukuhamba kunye nokhuseleko.Ukukhethwa okufanelekileyo kunye nokusetyenziswa kwe-lubricant kubalulekile ekuqinisekiseni ukusebenza kakuhle kunye nobude obude beevalvu zesango, kubandakanywa nezo zifakwe kwi-wellheads.Ngokusebenzisa i-lubricant ephezulu ehambelana neemeko zokusebenza kunye nezixhobo zeevalve, abaqhubi banokunceda ukunciphisa iimfuno zokugcinwa kunye nokwandisa ukuthembeka kweenkqubo zabo ze-valve ye-wellhead gate.
