を必要としない。 In the above, when the gate valve is in the closed state (FIG. 1), the links 10 are connected in series in a straight line, and
The link 10 presses against the first valve plate piece 21 at a substantially right angle, and this pressing force, via the spring 23, presses the second valve plate piece 22 against the periphery of the valve port 1b. This, together with the adhesion performance of the gasket 25, ensures that the valve port 1b is completely airtight. At the time of opening, the valve stem rotating section 40 operates, and the valve stem 1 moves to the first position.
When the link 10 is rotated 180 degrees clockwise as indicated by the arrow in the figure, the link 10 is bent by the pivoting of the first link 11 and the second link 12, and the upper part of the valve plate 20 is pulled toward the valve shaft 1, and the positioning groove 33a Remove the upper guide roller 31a from the When the valve shaft 1 further rotates, the valve plate 20 is pulled up along the guide groove 33, and when the valve shaft 1 has rotated approximately 180 degrees, the valve port 1b is completely opened as shown in the second figure. At this time, since the link 10 is divided and folded into the first arm 11 and the second arm 12, the valve plate 10 moves in a short arc with respect to the valve shaft 1, and does not require a large area.

閉鎖時の気密度が極めて高い。 In this way, the valve plate 20 has a first piece 21 and a second piece 2.
2 are superimposed on each other, and both pieces are attached to the elastic member 23 so that the gap can be changed, and are closely attached to the periphery of the valve opening via the gasket 25, so that the airtightness when the valve is closed is extremely high.

In addition, when the valve is opened, the valve plate can move along the ceiling and close to the valve stem.
The mechanism is compact and the height of the vacuum container can be shortened, among other benefits.
