阀装置
摘要：
本发明涉及一种阀装置(22)，其具有壳体(30)，流动通道(38)和设置在所述流动通道(38)中的阀体(36)，所述阀体具有密封段(34)，所述密封段在阀装置(22)关闭的情况下贴靠在壳体侧的密封座(32)上，其中，密封段(34)和密封座(32)一起构成密封区域(42)，其中，直接在所述密封区域(42)的上游在所述流动通道(38)中在阀装置(22)关闭的情况下存在衰减空间(44)，所述衰减空间由至少基本上垂直于所述阀体(36)的运动轴线(50)的限制壁(48)并且由与所述限制壁(48)成角度地设置的折流壁(46)限界，其中，所述限制壁(48)比所述折流壁(46)长。
摘要（英）：

A valve device (22) is described, comprising a housing (30), a flow duct (38) and a valve body (36) which is arranged in the flow duct (38) and has a sealing section (34) that bears against a housing-side sealing seat (32) when the valve device (22) is closed, wherein the sealing section (34) and the sealing seat (32) together form a sealing region (42), wherein there is a collapse zone (44) immediately upstream of the sealing region (42) in the flow duct (38) when the valve device (22) is closed, which collapse zone (44) is delimited by a boundary wall (48) that is at least substantially perpendicular with respect to a movement axis (50) of the valve body (36) and by a deflector wall (46) that is arranged at an angle with respect to the boundary wall (48), the boundary wall (48) being longer than the deflector wall (46).
