Ivalve yokhuseleko yejenereyitha yomphunga sisixhobo esizenzekelayo sokukhulula uxinzelelo. Umsebenzi oyintloko: Xa i-boiler yoxinzelelo idlula ixabiso elichaziweyo, inokuvula ngokuzenzekelayo ukukhupha uxinzelelo lwe-steam yokuthintela uxinzelelo ukuba luqhubeke nokunyuka. Kwangaxeshanye, inokuvakala i-alam yomsindo ukulumkisa abasebenzi bebhoyila ukwenzela ukuba kuthathwe amanyathelo ayimfuneko ukunciphisa uxinzelelo lwebhoyila ukuqinisekisa ukhuseleko lwebhoyila kunye ne-injini yomphunga. Ukhuseleko.
Xa uxinzelelo lwebhoyila luwela kwixabiso elivumelekileyo, i-valve yokhuseleko inokuzivala ngokwayo, ukwenzela ukuba ibhoyila ikwazi ukusebenza ngokukhuselekileyo ngaphakathi kwinqanaba elivumelekileyo loxinzelelo kwaye ithintele ibhoyila ekucinezelekeni ngokugqithisileyo kwaye ibangele ukuqhuma. Ivalve yokhuseleko yenziwe ikakhulu sisitulo sevalve, isiseko sevalve kunye nesixhobo soxinzelelo.
Umgaqo wokusebenza wevalve yokhuseleko: Itshaneli ekwisitulo sevalve yokhuseleko iqhagamshelwe kwindawo yomphunga kwibhoyila. I-valve core icinezelwe ngokuqinileyo kwisitulo sevalve ngoxinzelelo olwenziwa sisixhobo soxinzelelo. Xa ivalve ivaliwe; ukuba uxinzelelo lomoya kwibhoyila luphezulu kakhulu, umphunga uya kuba namandla okuxhasa isiseko sevalve nawo ayanda. Xa amandla axhasayo emkhulu kunoxinzelelo lwesixhobo sokucinezela kumbindi wevalve, undoqo wevalve uyaphakanyiswa kude nesihlalo sevalve, ishiya ivalve yokhuseleko ikwimo evulekileyo, ngaloo ndlela ivumela umphunga kwibhoyila ukuba ukhutshwe ukuze ufezekiseke. isiqabu. Injongo yokucinezela. Xa uxinzelelo lomoya kwibhoyila lusihla, amandla omphunga kumbindi wevalvu nawo ayancipha. Xa uxinzelelo lomphunga kwijenereyitha yomphunga wombane ubuyela kwinto eqhelekileyo, oko kukuthi, xa amandla omoya engaphantsi koxinzelelo lwesixhobo soxinzelelo kwisiseko sevalve, ivalve yokhuseleko iya kuvala ngokuzenzekelayo.
Ukuthintela iingozi ezinkulu, ukongeza ivalve yokhuseleko kwijenereyitha yomphunga yindlela eqhelekileyo yokhuseleko edlala indima ebalulekileyo ekukhuseleni ishishini. Ukuqwalasela i-valve yokhuseleko kunokuphepha ngokufanelekileyo iingozi zokhuseleko ezibangelwa ukunxitywa komlawuli woxinzelelo, umonakalo wepayipi, njl., kunye nokuphucula ngokufanelekileyo ukusebenza kokhuseleko lwezixhobo.
Iivalve zokhuseleko ziivalve ezizenzekelayo ezisetyenziswa kakhulu kwiijenereyitha zomphunga, iinqanawa zoxinzelelo (kubandakanywa nezicoci zoxinzelelo oluphezulu) kunye nemibhobho yokulawula uxinzelelo lokungadluli kwixabiso elichaziweyo kwaye idlale indima ebalulekileyo ekukhuseleni ukhuseleko lomntu kunye nokusebenza kwezixhobo. Iindawo zokuvula kunye nokuvala i-valve yokhuseleko zikwimeko evaliweyo ngokuqhelekileyo ngenxa yamandla angaphandle. Xa uxinzelelo oluphakathi kwisixhobo okanye umbhobho lukhuphuka ngaphezu kwexabiso elichaziweyo, uxinzelelo oluphakathi kwipayipi okanye izixhobo zithintelwe ukuba zigqithise ixabiso elichaziweyo ngokukhupha i-medium ngaphandle kwenkqubo.
