Abstract: A valve device includes a housing, a flow duct and a valve body. The valve body is arranged in the flow duct and has a sealing section that bears against a housing-side sealing seat when the valve device is closed. The sealing section and the sealing seat together form a sealing region. There is a collapse zone immediately upstream of the sealing region in the flow duct when the valve device is closed. The collapse zone is delimited by a boundary wall that is at least substantially perpendicular with respect to a movement axis of the valve body and by a deflector wall that is arranged at an angle with respect to the boundary wall. The boundary wall is longer than the deflector wall.

Abstract translation: 阀装置包括壳体，流动管道和阀体。 阀体布置在流动管道中，并且当阀装置关闭时具有密封部分，该密封部分抵靠壳体侧密封座。 密封部和密封座一起形成密封区域。 当阀装置关闭时，在流动管道中的密封区域的紧邻上游处存在塌陷区域。 塌陷区域由相对于阀体的移动轴线至少基本垂直并且相对于边界壁以一定角度布置的偏转器壁的边界壁限定。 边界壁比导流墙长。
