摘　　要：针对发明问题解决理论(TRIZ)方法与仿生学的优缺点,提出基于TRIZ与仿生学相结合的仿生创新设计方法。采用该方法,针对传统止回阀如球形止回阀、对夹式止回阀等流阻系数大的缺点,设计出一种新型的金字塔型多瓣止回阀,当流体正向流动时,阀瓣打开并位于流道侧面;当流体回流时,阀瓣关闭处于斜立状态,因此可以有效地减少阀瓣开关行程,并减小对流体的阻力与作用时间,降低了流阻系数。实验证明:该止回阀阀门的流通能力很强,能起到一定的节能作用。Analyses the advantages and disadvantages of TRIZ methods and bionics, the innovative design approach based on a combination of TRIZ and bionics was put forward. The traditional check valves such as ball valve and wafer check valves have some shortcomings, such as the high resistance coefficient. Basing on this method, a new type of pyramid orange-peel check valve was design. When the disc is open, the peels are beside the channel;when the disc is close,the peels are in the form of pyramid, thus, it can effectively reduce the area of obstructing water. Experimental analysis was done for the flow field of the check valve. The results show that the flow resistance coefficient is much less than that of conventional check valve. It also shows that it has better capacity for water flowing and energy conservation.
