止回阀
摘要：
本发明涉及一种止回阀(10)，该止回阀(10)具有阀壳体(12)和关闭元件(22)，在阀壳体(12)上形成有阀座(18)，阀座(18)设计为相对于流动方向(S)的斜面，关闭元件(22)包括至少一个片状关闭舌片(24)，关闭舌片(24)由弹性地可变形的材料制成，在关闭位置中，关闭舌片(24)接触阀座(18)，在开启位置中，关闭舌片(24)从阀座(18)抬起，以便使流体(30)通过，其中，止动元件(34)布置在关闭舌片(24)的背离阀座的一侧，关闭舌片(24)能够抵接止动元件(34)，以便限制关闭舌片(24)从阀座抬起的距离。
摘要（英）：

The invention relates to a check valve (10) having a valve housing (12) on which a valve seat (18) is formed, designed as an angled surface relative to a flow direction (S), and having a blocking element (22) comprising at least one flat blocking tab (24) made of an elastically deformable material, contacting the valve seat (18) in a blocked position and raised from the valve seat (18) in an open position, in order to allow the passage of fluid (30), wherein a stop element (34) is disposed on the side of the blocking tab (24) facing away from the valve seat, against which the blocking tab (24) can strike, in order to limit the distance that the blocking tab (24) can rise from the valve seat.
