Ivalve yokhuseleko sisixhobo sokhuseleko esizenzekelayo esinokukhulula ngokukhawuleza umphunga xa uxinzelelo luphezulu kakhulu ukuthintela iingozi zokudubula.Ingumgca wokugqibela wokukhusela kwiingozi zejenereyitha yomphunga kwaye ikwayinto ephambili yesixhobo sokuqinisekisa ukhuseleko lobomi kunye nokuthembeka kwezixhobo.Ngokuqhelekileyo, i-generator yomphunga kufuneka ifakwe kunye neevalvu ezimbini zokhuseleko.Ngokuqhelekileyo, ukufuduka okulinganiselwe kwevalve yokhuseleko kufuneka kube ngaphantsi komthamo omkhulu wokucubungula we-generator ye-steam ukuqinisekisa ukusebenza okuqhelekileyo kumthwalo ophezulu.
Ukugcinwa nokugcinwa kweevalvu zokhuseleko nako kubaluleke kakhulu.Ngethuba lokusetyenziswa, ukuchaneka kunye nokuvakalelwa kwe-valve yokukhusela kufuneka kuhlolwe rhoqo, kwaye ukugcinwa kufuneka kuqhutywe ngokuhambelana nemiyalelo yokusetyenziswa kunye nokugcinwa kwencwadana.Ukuba iimpawu zokungaphumeleli okanye ukungasebenzi zifunyenwe kwi-valve yokukhusela, kufuneka ithathelwe indawo okanye ilungiswe ngexesha ukuze kuqinisekiswe ukusebenza okukhuselekileyo kwejeneretha ye-steam.
Ke ngoko, ivalve yokhuseleko kwijenereyitha yomphunga sisixhobo esiyimfuneko.Akuyena kuphela umgca wokugqibela wokukhusela ukuqinisekisa ukhuseleko lwabasebenzi, kodwa kunye nomlinganiselo obalulekileyo wokukhusela ingqibelelo kunye nokuzinza kokusebenza kwezixhobo.Ukuze kuqinisekiswe ukusebenza ngokukhuselekileyo kwejeneretha ye-steam, kufuneka sinikele ingqalelo kwiinkalo ezininzi ezifana nokukhethwa, ukufakwa, ukugcinwa kunye nokugcinwa kwe-valve yokukhusela.
