Vacuum negative- ivalvu yokuphepha yokucindezela

I-A72W-10P, A72W-10R

I-A72W isetshenziswa ohlelweni olubi lwengcindezi enezinga lokushisa≤200℃. Lapho ingcindezi engalungile esitsheni idlula inani elivunyelwe, i-valve izovuleka ngokuzenzakalelayo futhi ibambe umoya. Lapho ingcindezi engalungile esitsheni ifinyelela inani elivunyelwe, i-valve izovala ngokuzenzakalelayo ukuze ivikele imishini kanye nesistimu. Izofakwa ezinhlelweni ezivamile zokucindezela okungeyona embi. Lapho i-valve yokukhipha yesitsha kanye nesistimu ingakavulwa, ekhiqiza ukucindezela okungalungile, le valve izovuleka ngokuzenzakalelayo.
