摘要： To provide a valve device in which different driving mechanisms, that is, a rotating mechanism and a lifting mechanism are controlled by one driving source, thereby realizing compactness and high reliability of the driving mechanisms.
A valve device includes: a valve element unit 52 closing or opening a first opening 46 of a casing 44; a valve element driving unit 11 rotating the valve element unit 52 to move the valve element unit 52 to a position facing the first opening 46, and moving the valve element unit 52 in a radial direction to make the valve element unit 52 seated on the first opening 46; a first sealing member 58 provided on the valve element unit 52; and stoppers 39A, 39B, 35 restricting the rotation of the valve element unit 52, wherein the valve element driving unit 11 includes: a support 13 rotatably supporting the valve element unit 52; a shaft part 17 which has an eccentric shaft portion 17B connected to the valve element unit 52 and having a center located at a position a predetermined distance apart from a center of the rotation; and a driving source 66 rotating the shaft part 17.摘要翻译： 提供一种阀装置，其中不同的驱动机构，即旋转机构和升降机构由一个驱动源控制，从而实现驱动机构的紧凑性和高可靠性。 阀装置包括：关闭或打开壳体44的第一开口46的阀元件单元52; 使阀芯单元52旋转而使阀芯单元52移动到与第一开口46对置的位置并使阀芯单元52向径向移动而使阀芯单元52落座于第一 开放46; 设置在阀体单元52上的第一密封部件58; 以及限制阀体单元52的旋转的止动件39A，39B，35，其中，阀体驱动单元11包括：支撑件13，其可旋转地支撑阀件单元52; 具有偏心轴部17B的轴部17，该偏心轴部17B与阀体单元52连接，且中心位于离旋转中心预定距离的位置; 以及使轴部17旋转的驱动源66。

摘要： To provide a valve element unit and a gate valve apparatus which realize a reduction in manufacturing cost by a compact and simple structure and smooth rotary driving of the valve element without greatly moving the valve element in the direction of the center of rotation when the valve element is rotary driven. When a valve element unit 52 is rotary driven by valve element driving mechanisms 54, a rotary drive radius R2 of longitudinal both end sides of a first valve element 56 is smaller than a rotary drive radius R1 of a longitudinal center side of the first valve element 56. Therefore, even when a sidewall is formed on a longitudinal outer side of a transfer port 46 of a casing 44, part of the valve element unit 52 does not come into contact (interfere) with the sidewall, which makes it possible to rotary drive the valve element unit 52 only by slightly moving the valve element unit 52 in a direction of the center of rotation, without greatly moving the valve element unit 52 in the direction of the center of rotation at the time of the rotary driving.
