I-valve yokuphepha eyinhloko
Le valve isetshenziselwa ama-boilers wezitshalo zamandla, iziqukathi zokucindezela, ingcindezi kanye nedivaysi yokunciphisa izinga lokushisa nezinye izinsiza. Isebenzela ukuvimbela ukucindezela okungaphezu kwenani eliphezulu elivunyelwe lokucindezela futhi iqinisekise ukuphepha kwedivayisi lapho isebenza.
I-1, Lapho ingcindezi ephakathi ikhuphukela kumfutho obekiwe, i-valve yokuphepha yomfutho iyavuleka, futhi i-medium epayipini lomfutho ingena egumbini le-piston le-valve yokuphepha eyinhloko isuka epayipini lomfutho, iphoqe i-piston ukuthi yehle, bese i-valve ngokuzenzakalelayo. ivula; lapho i-valve yokuphepha kwe-impulse ivala, i-disc nayo izovala ngokuzenzakalelayo.
I-2, Indawo evaliwe yenziwe ngensimbi engagqwali ye-Fe ngokumboza ukushisela. Ngokwelashwa okushisayo, ukumelana nokugqoka kanye ne-anti-rosion ye-disc kuyathuthukiswa.
1, I-valve yokuphepha eyinhloko izofakwa ngokuqondile endaweni ephakeme kakhulu yedivayisi.
2, I-valve yokuphepha eyinhloko izoboshelwa phezu kwesiphango, esisekela amandla asesihlalweni sangemuva akhiqizwa inqubo yokukhipha isitimu yevalvu yokuphepha eyinhloko.
3, Ipayipi lokukhipha umoya kufanele liqukathe ukukhanya okukhethekile ukuvimbela amandla esisindo sawo ukuthi asebenze ngokuqondile kuvalvu yokuphepha eyinhloko. I-flange yokuxhuma phakathi kwe-valve yokuphepha eyinhloko kanye nepayipi yokukhipha izoqeda noma yikuphi ukucindezeleka okwengeziwe.
4, Ezindaweni eziphansi kakhulu zepayipi lokukhipha amanzi, ukugeleza kwamanzi kufanele kucatshangelwe ukuze kugwenywe ukukhiqiza isando samanzi ngenkathi kuthululwa isitimu.
