Isihlungi se-duplex sibizwa nangokuthi isihlungi esishintshayo se-duplex.Yakhiwe ngezihlungi ezimbili zensimbi engagqwali ngokuhambisana.Izindlu zokuhlunga isikhwama se-Duplex ngokuvamile zisetshenziselwa isimo esiqhubekayo sokusebenza, Lapho indlu yokuhlunga eyodwa isebenza, Ngenkathi enye indlu yokuhlunga ingaphansi kokuhlanza.Kukhona i-tee kanye ne-valve yokulawula engxenyeni yokungena, Ngakho-ke isiqondiso sokugeleza singashintshwa njengoba kudingekile.
Uma isici sokuhlunga sivimbelwe ngokwezinga elithile phakathi nenqubo yokusebenza yesihlungi esivamile, inqubo yokuhlunga kufanele imiswe ngaphambi kokuhlanza noma ukuhlolwa.Isihlungi se-duplex siyixazulula ngokuphumelelayo inkinga kule ndawo, futhi ukuhlanza okungapheli kwenziwa ukuze kuzuzwe amahora angu-24 omsebenzi oqhubekayo.Thuthukisa ukusebenza kahle komsebenzi futhi wonge isikhathi
Singakwazi ukwenza ngokwezifiso i-valve namapayipi njengemfuneko yekhasimende.
