| 專利摘要 | 本創作揭露一種大尺寸高真空閘閥，包含固定裝置。固定裝置用以將第一O型環固定於本體上，其中本體上定義第一固定路徑。第一固定路徑具有第一線性部與第一非線性部。固定裝置包含第一限位構件以及第二限位構件。第一限位構件設置於本體之第一側。第二限位構件設置於本體上，並與第一限位構件沿著第一非線性部形成第一非線性溝槽。其中部分第一O型環係夾擠於第一限位構件與第二限位構件之間而固定於第一非線性溝槽中。 The invention discloses a large-size high vacuum valve including a fixing apparatus for fixing a first o-ring on a main body, wherein a first fixing path is defined on the main body. The first fixing path has a first linear portion and a first nonlinear portion. The fixing apparatus includes a first retaining member and a second retaining member. The first retaining member is disposed at a first side of the main body. The second retaining member is disposed on the main body and forms a first nonlinear groove with the first retaining member along the first nonlinear portion, wherein, a part of the first o-ring is clamped between the first retaining member and the second retaining member to fix in the first nonlinear groove. |
