Ivalve yokhuseleko lwevalve yebhoyila uhlalutyo oluxhaphakileyo lweemfuno zevalvu yebhoyila yokhuseleko lwamalahle
Isishwankathelo: kuhlalutywe ukuvuza kwevalve yokhuseleko lwebhoyila, ukuvuza komphezulu womzimba, intshukumo yevalvu yokhuseleko emva kokuba ivalve yokhuseleko ingenzeki, isitulo sevalvu yokhuseleko esishiywe kwivalve yokukhulula ukulibaziseka ukubuyela esitulweni umva ixesha elide kunye noxinzelelo olusezantsi lokhuseleko. ivalve, i-frequency jump kunye ne-flutter kunye nezinye iziphene eziqhelekileyo, kunye nokubeka phambili isisombululo sonobangela wengxaki.
1. Iimfuno zevalve yokhuseleko yebhoyila yebhoyila yomlilo wamalahle umthamo webhoyila umphunga mkhulu kune-0.5t/h, ubuncinci iivalvu zokhuseleko ezi-2 zifakiwe, umthamo wokunyuka komphunga ungaphantsi okanye ulingana no-0.5t/h, ubuncinci ukhuseleko olu-1. ivalve. Xa amandla okushisa alinganisiweyo kwibhoyila yamanzi ashushu angaphezu kwe-1.4MW, ubuncinane iivalve ezi-2 zokhuseleko ziya kufakwa; Xa unikezelo lobushushu olulinganisiweyo lungaphantsi okanye lulingana ne-1.4MW, ubuncinane i-valve yokhuseleko iya kufakwa.
Indawo yokuphuma economizer eyahlulayo, indawo yokuphuma yesifudumezisi esiphezulu somphunga, kufuneka ixhotyiswe ngevalve yokhuseleko. Ibhoyila enoxinzelelo lomphunga olulinganiselweyo ngaphantsi kwe-0.1mpa inokusebenzisa ivalve yokhuseleko lobunzima obumileyo okanye isixhobo sokhuseleko sohlobo lwesitywina samanzi.
I-valve yokhuseleko kufuneka ifakwe ngokuthe tye, kwaye kufuneka ifakwe kwi-drum, indawo ephezulu yebhokisi yokuqokelela. Phakathi kwevalve yokhuseleko kunye negubu okanye phakathi kwevalve yokhuseleko kunye nebhokisi yokuqokelela, akusayi kubakho mbhobho wokuphuma kunye nevalve yomphunga. I-YONKE yomoya wokukhupha umphunga wevalve yokhuseleko kufuneka ibe mkhulu kunorhatyazo oluyilwe kwibhoyila, kwaye emva kokuba zonke iivalve zokhuseleko ezikwidrum kunye ne-superheater zivuliwe, uxinzelelo lomphunga kwidrum aluyi kudlula amaxesha angama-1.1 kuxinzelelo loyilo. Umthamo wokukhupha wevalve yokhuseleko lwe-superheater kufuneka uqinisekise ukuba i-superheater ifumana ukupholisa okwaneleyo phantsi komthamo wokukhupha kwaye ayiyi kutshiswa.
Ivalve yokhuseleko lwebhoyila ethe nkqo kufuneka ibe nesi sixhobo silandelayo: ivelufa yokhuseleko lohlobo lwasentwasahlobo kufuneka ibe nomqheba wokuphakamisa kwaye ithintele isixhobo sokulungisa isikhonkwane. I-valve yokhuseleko lohlobo lwe-lever kufuneka ibe nesixhobo sokuthintela ubunzima ukuba bungahambi ngokwaso kunye nesakhelo sesikhokelo sokunciphisa i-lever ekuphumeni. Ivalve yokukhulula ubunzima obumileyo iya kuba nesixhobo sokuthintela ubunzima ekubhabheni.
Kwiibhoyila ezinoxinzelelo lwe-steam olulinganiswe ngaphantsi okanye olulingana ne-3.82Mpa, i-diameter yokhuseleko lomqala ayiyi kuba ngaphantsi kwe-25mm; Kwiibhoyila ezinoxinzelelo lomphunga olulinganiswe ngaphezu kwe-3.82Mpa, idiameter yomqala yevalve yokukhulula ayizuba ngaphantsi kwe-20mm. Iivalve ezininzi zokhuseleko zifakwe kumbhobho omfutshane odityaniswe ngokuthe ngqo kunye ne-drum, kwaye indawo enqamlezileyo yombhobho omfutshane ayifanele ibe ngaphantsi kwenani lendawo yombhobho wokukhupha zonke iivalve zokhuseleko.
Ivalve yokhuseleko kufuneka ixhotyiswe ngokubanzi ngombhobho wokukhupha, umbhobho wokukhupha kufuneka ube ngaphandle ngokuthe ngqo kangangoko kunokwenzeka, kwaye ube nendawo eyaneleyo enqamlezileyo, ukuqinisekisa ukuba umphunga ogudileyo. Umzantsi womgca wokukhupha ivalve yokunceda uya kuxhotyiswa ngomgca wamanzi kwindawo ekhuselekileyo. Iivalvu aziyi kufakwa kumbhobho wokukhupha okanye kumbhobho wokubonelela. I-VALVE YOKHUSELEKO KWI-ECONOMIZER IZA KUFANISWA NGOMbhobho WOKUKHUTHAZA KWAYE IBAQELEKILE KWINDAWO EKHUSELEKILEYO. Akukho VAVAVA KUYA KUFAKWA KUMHOMBO WOKUKHUPHA.
