具体实施方式
本发明主要由一个蝶板04、两个阀体02，02a、一个密封圈03、进口清洗管01和出口清洗管01a组成，第一螺栓16将上面装置固定在一起，第二螺栓17将上面装置及连接体05固定在一起，而两个连接体05在本装置中仅仅起连接管道的作用，连接轴07将来自于气缸09的能量驱动蝶板04，气动支架08用于固定气缸图1.1-图1.3。防混蝶阀单蝶板4的圆周外沿有圆弧形凹槽，两凹槽一端通过小孔腔室连通，一端分别与第一小孔腔室R3a、R6a和第一小孔腔室R3a、R6a连接，这样蝶板本身构成了一个通道，此通道一旦构成密闭的条件，便形成循环通道，清洗液便通过其中进行清洗图3.1-图3.5。
防混蝶阀的密封圈03材料为弹性橡胶材料，圆周上紧紧包裹着蝶板04，对两阀体02，02a和蝶板04起密封作用，另特别设计了两个密封圈小孔腔室R2,R2a，有下面两个作用：1，对蝶板04环形的腔室R4,R4a的密封，构成一组密闭的腔室，让蝶板04环形凹槽通道可以构成循环通道，实现清洗液在装置中的循环清洗；2，密封圈小孔腔室R2,R2a对蝶板小孔腔室R6,R6a通过蝶板的旋转构成通和关，实现清洗液的通和关图1.3，图2.3。
防混蝶阀的两个阀体01，01a上设计了两个小孔腔室R1,R1a，此腔室一端正好与两个密封圈小孔腔室R2,R2a分别固定相通，一端与两个清洗管分别固定相通，因此两个小孔腔室R1，R1a至密封圈小孔腔室腔室R2,R2a都始终和清洗液相通图1.1
蝶板04在外力驱使下作90°旋转，如果蝶板在图2.1位置状态，则此时蝶板小孔腔室R6,R6a与密封圈小孔腔室R2,R2a是开通的，而蝶板环形的凹槽与密封圈03形成密封的环形的腔室R4,R4a，清洗液体可以通过凹槽和整个循环通道流通，这样实现密封圈3与环形凹槽封闭部分的滞留液体或混合液体的清洗，保证蝶板两边管道的介质纯净，无污染图2.1，图2.3。
同时蝶板在关闭状态下，如果蝶板两边管道的液体发生泄漏，那么，泄漏的液体可以进入蝶板环形的腔室R4,R4a再通过循环清洗通道流出清洗管外，实现泄漏自检图2.1
蝶板在外力作用下从图2.1作90°旋转，蝶板小孔腔室R6,R6a与密封圈小孔腔室R2,R2a随着旋转将发生逐渐关闭直到全部关闭，蝶板04与密封圈03的密封将发生开启直到全部开启，结果是清洗循环通道被阻断，实现清洗液关闭而蝶板两边通道介质液体可以流通图1.1，图1.2
如图1.1，气缸在气嘴15充气压力和内部弹簧复位张力的作用下驱动连接轴07转动，从0°-90°，再从90°-0°，循环往复，连接轴设计有方芯内孔，带动有方芯的蝶板04一起转动。
当蝶板转动到图1.1状态时，蝶板与密封圈的打开，管道处于全开状态，蝶板小孔腔室R6,R6a与密封圈小孔腔室R2,R2a关闭，整个清洗循环通道处于关闭状态，而蝶板两边通道的介质液体是流通的图1.1-图1.3。
当蝶板旋转继续旋转，蝶板小孔腔室R6,R6a也绕轴心旋转，直到与密封圈小孔腔室R2,R2a连通，此时蝶板与密封圈03处于关闭，蝶板04两边管道介质液体被隔断，不能混合，同时，蝶板04被密封圈03封闭形成环形的腔室R4,R4a，再加上蝶板的特殊设计，使环形的腔室R4,R4a一端通过第二小孔腔室R5连通，一端分别通过第一小孔腔室R3,R3a与蝶板小孔腔室R6,R6a连通，这样，进口清洗管01和出口清洗管01a从进口到出口，中间的所有通道都是开通的，其路径是：进口清洗管01至小孔腔室R1至密封圈小孔腔室R2至蝶板小孔腔室R6至小孔R3至腔室R4至第二小孔腔室R5至腔室R4a至第一小孔腔室R3a至蝶板小孔腔室R6a至密封圈小孔腔室R2a至小孔腔室R1a至出口清洗管01a于是，当清洗液通过环形的腔室R4,R4a后，滞留在环形的腔室R4,R4a的混合液体被一起带走，环形的腔室R4,R4a得到清洗，防止管道两边的介质液体混合，产生混合污染，保证管道两边液体纯净同时，如果蝶板04与密封圈03之间发生泄漏，泄漏液体进入环形的腔室R4,R4a，同样泄漏液体通过清洗循环通道流出，实现管道液体泄漏自检。
阀体02，02a小孔腔室R1,R1a一端与进口清洗管01和出口清洗管01a固定相通，另一端与密封圈小孔腔室R2,R2a固定相通，进口清洗管01和出口清洗管01a与清洗液相连，一进口一出口，因此小孔腔室R1,R1a和密封圈小孔腔室R2,R2a都充满着清洗液体，保证清洗液在清洗循环通道中能够畅通。
