    • A valve in accordance with the reduction in diameter of piping in a vacuum discharge system, the reduction realizing downsizing of apparatuses for a vacuum discharge system and resultant reduced costs and shortened time for vacuum discharge. In the valve, inside corrosion, clogging, seat leakage, etc. by accumulation of dissociated products produced by decomposition of gas can be prevented from occurring. Specifically, passive aluminum is used for piping components, such as the valve, adapted for a vacuum discharge system so as to control decomposition of gas caused by rise in temperature during baking, so that components suitable for the reduction in diameter sizes in the vacuum discharge system are provided. Corrosion, clogging, seat leakage, etc. caused by decomposition of gas are prevented from occurring.
    • 根据真空排放系统中的管道直径的减小的阀,减小了实现真空排放系统的装置的小型化并且导致降低的成本并缩短了真空排放的时间。 在阀中,可以防止由气体分解产生的解离产物的积聚导致内部腐蚀,堵塞,阀座泄漏等。 具体来说,被动铝被用于管道部件,例如适用于真空排放系统的阀门,以便控制在烘烤过程中温度升高引起的气体分解,使得适合于减小真空放电中直径尺寸的部件 系统。 防止由气体分解引起的腐蚀,堵塞,阀座泄漏等。

    • A diaphragm valve for a vacuum evacuation system applicable to a semiconductor manufacturing system. Corrosion of members due to deposition/adhesion of products produced by thermolysis of gas, clogging due to products, and seat leakage are prevented. This diaphragm valve leads to reduction in the scale of the vacuum evacuation system facility, reduction in cost, and reduction in diameter of piping of the vacuum evacuation system for the purpose of decrease in vacuum evacuation time. Specifically, the diaphragm valve (1) comprises a body (2) having an inlet passage (6), an outlet passage (7), and a valve seat (8) provided between the passages, a diaphragm (3) which is provided to the body (2) and can be separated from the valve seat (8) and brought into contact with the same, and drive means (4) provided to the body (2) and adapted to separate the diaphragm (3) from the valve seat (8) and to bring the diaphragm (3) into contact with the same. The portion (25) of the body (2) and the portion (25) of the diaphragm (3) both coming into contact with a fluid are coated with a synthetic resin coating (5) of predetermined thickness.
    • 一种适用于半导体制造系统的真空排气系统的隔膜阀。 防止由于气体的热分解产生的产品的沉积/粘附引起的部件的腐蚀,产品堵塞和阀座泄漏。 为了减少真空排气时间,该隔膜阀导致真空抽空系统设备的规模减小,成本降低,真空排气系统的管道直径减小。 具体地说,隔膜阀(1)包括具有入口通道(6),出口通道(7)和设置在通道之间的阀座(8)的主体(2),隔膜(3)设置成 主体(2)并且可以与阀座(8)分离并与其接触;以及驱动装置(4),其设置在主体(2)上并且适于将隔膜(3)与阀座 (8)并使隔膜(3)与其接触。 主体(2)的部分(25)和隔膜(3)的与流体接触的部分(25)都涂覆有预定厚度的合成树脂涂层(5)。
