Abstract

本实用新型涉及单向阀的技术领域，尤其涉及一种高频快速响应的微泵用单向阀，包括依次层叠的第一板、瓣膜及第二板，第一板表面设有多个均匀间隔排布的第一通孔；第二板表面设有覆盖所述第一通孔排布区域的开放区；瓣膜设置于所述第一板与所述第二板之间，且表面设有多个间隔排布的第二通孔，所述第二通孔与所述第一通孔在平面上呈错位分布并暴露于开放区中；通过以上设计，使流体反向流动时，流体可通过开放区直接冲击在瓣膜表面驱使瓣膜封闭第一通孔实现反向截止，可有效降低流体渗透至狭窄间隙的延迟，从而减少了阀门的闭合响应时间，并且还可降低流体在第二板和瓣膜之间渗透的压力损失，从而有效提升了阀门的高频响应性能。
