SCAR污水复合式排气阀原理与CARX复合式排气阀相同，只是将结构略作改动，即将阀体加高，杠杆机构稍微改动（如图）。这样控制部分降低，使污物只在阀体下部，不会缠绕上部排气部分机构，不影响排气，不致漏水，排气量与nclick="null;if（arg1.onmousemove）arg1.onmousemove=null;if（arg1.onmouseover）arg1.onmouseover=null;if（arg1.ondblclick）arg1.ondblclick=null;if（arg1.onmouseenter）arg1.onmouseenter=null;if（arg1.onmouseleave）arg1.onmouseleave=null;return" result;}?="" style="font-family: simsun, Verdana, Lucida, Arial, Helve; font-size: 12px; white-ce: normal;">CARX型相同。
