Ijenereyitha nganye yomphunga kufuneka ixhotyiswe ubuncinane ngeevalvu ezi-2 zokhuseleko ezinokufuduswa okwaneleyo. Ivalve yokhuseleko yindawo yokuvula kunye neyokuvala ekwimeko eqhelekileyo evaliweyo phantsi kwesenzo samandla angaphandle. Xa uxinzelelo oluphakathi kwisixhobo okanye umbhobho lukhuphuka ngaphezu kwexabiso elichaziweyo, i-valve yokukhusela idlula kwi-valve ekhethekileyo ekhupha i-medium ngaphandle kwenkqubo ukukhusela uxinzelelo oluphakathi kumbhobho okanye izixhobo ezingaphezulu kwexabiso elichaziweyo.
Iivalve zokhuseleko zi-automatic valves kwaye zisetyenziswa kakhulu kwiibhoyili, iijeneretha zomphunga, iinqanawa zoxinzelelo kunye nemibhobho yokulawula uxinzelelo olungagqithisi kwixabiso elichaziweyo. Njengenxalenye ebalulekileyo ye-boilers ye-steam, iivalve zokhuseleko zineemfuno eziqinileyo zofakelo. Oku kukuqinisekisa ukuba umphunga Isiseko sokusebenza okuqhelekileyo kwejeneretha.
Ngokwesakhiwo sevalve yokhuseleko, yahlulwe yaba ivelufa yokhuseleko lwehamile enzima, ivalve yokhuseleko lokuphakamisa i-micro-lift kunye nevalve yokhuseleko lwe-pulse. Ngesiseko sokuthobela iimfuno zokufakela i-valve yokhuseleko, nikela ingqalelo kwiinkcukacha ukuphepha imiphumo emibi kwinkqubo yokusebenza. .
Ekuqaleni,indawo yokufakwa kwevalve yokhuseleko ifakwe ngokubanzi phezulu kwijenereyitha yomphunga, kodwa ayifanele ixhotyiswe ngemibhobho yokuphuma kunye neevalvu zokuthatha umphunga. Ukuba i-valve yokhuseleko lohlobo lwe-lever, kufuneka ixhotyiswe ngesixhobo sokuthintela ubunzima ukuba bungahambi ngokwawo kunye nesikhokelo sokunciphisa ukuphambuka kwe-lever.
Isibini,inani leevalvu zokhuseleko ezifakiweyo. Kwiijenereyitha zomphunga ezinomthamo wokuphefumula> 0.5t / h, ubuncinane kufuneka kufakwe iivalvu zokhuseleko ezimbini; iijenereyitha ze-steam ezinomthamo olinganisiweyo we-evaporation ≤0.5t / h, ubuncinane i-valve yokhuseleko kufuneka ifakwe. Ukongezelela, iinkcukacha zevalve yokukhusela i-steam generator ihambelana ngokuthe ngqo nokusebenza kakuhle kwejeneretha ye-steam. Ukuba umlinganiselo woxinzelelo lomphunga wejenereyitha yomphunga ngu-≤3.82MPa, i-orifice diameter yevalve yokhuseleko akufanele ibe <25mm; kunye neebhoyila ezinoxinzelelo lwe-steam> 3.82MPa, i-orifice diameter yevalve yokhuseleko akufanele ibe <20mm.
Ukwengeza,ivalve yokhuseleko ngokuqhelekileyo ixhotyiswe ngombhobho wokukhupha, kwaye umbhobho wokukhupha uqondiswe kwindawo ekhuselekileyo, ngelixa ushiya indawo eyaneleyo ye-cross-sectional ukuqinisekisa ukuhamba kakuhle kwe-steam yokukhupha kwaye unike ukudlala ngokupheleleyo indima yevalve yokhuseleko. Umsebenzi we-valve yokukhusela i-steam generator: ukuqinisekisa ukuba i-generator ye-steam ayisebenzi kwi-overpressure state. Okokuthi, ngexesha lokusebenza kwejeneretha ye-steam, ukuba uxinzelelo ludlula uxinzelelo oluncinci lokusebenza, i-valve yokhuseleko iya kuhamba ukunciphisa i-generator ye-steam ngokukhupha. Umsebenzi woxinzelelo uthintela ukuqhuma kwejeneretha ye-steam kunye nezinye iingozi ngenxa yoxinzelelo olugqithisileyo.
Iijenereyitha zomphunga zeNobeth zisebenzisa iivalvu zokhuseleko ezikumgangatho ophezulu ezikumgangatho ophezulu, uyilo lwesakhiwo senzululwazi, ufakelo lwendawo efanelekileyo, umsebenzi omhle, kunye nokusebenza ngokungqongqo ngokungqinelana nemigangatho. Kuye kwavavanywa amaxesha amaninzi ngaphambi kokuba ushiye umzi-mveliso ukuze kuqinisekiswe ukhuseleko lwejenereyitha yomphunga, kuba luluhlu olubalulekileyo olusindisa ubomi kwijenereyitha yomphunga kunye nomgca wokusindisa ubomi bokhuseleko lomntu.
