に対接されてシールが達成される。 1 and 2 show a conventional high vacuum gate valve, 1 is a valve seat with a diameter of approximately 100 mm, 2 is a disk-shaped valve disk that is in contact with this, and 3 is a valve seat that is connected to the valve disk 2. 1 is a valve stopper that presses the valve stopper; 4 is a spring connected between the valve stopper 3 and the valve desk 2; 5 is a spring that connects the valve stopper 3 to the valve desk 2 via a piston rod 6;
7 is a valve desk stopper, 8 is a roller provided at the end of the valve desk 2 so as to abut against this stopper 7, 9 and 10 are the valve desk 2 and the valve stopper. 3
Recessed grooves each having a rectangular cross section are provided on opposing surfaces of the recessed grooves 9 and 10, and reference numeral 11 indicates a prismatic body having a rhombic cross section perpendicular to the longitudinal axis, which is inserted into the recessed grooves 9 and 10 in common, and drives the piston cylinder 5. Figures 1 and 2
In the figure, when the piston rod 6 is moved downward, the valve stopper 3 is moved to the valve desk 2 via the spring 4.
After the roller 8 of the valve disk 2 hits the stopper 7, only the valve stopper 3 is moved in the radial direction of the valve disk 2 against the spring 4, and as a result, the grooves corresponding to each other are moved downward. 9 and 10 are shifted, and the valve desk 2 is moved to the valve seat 1 by the action of the columnar body 11.
A seal is achieved by being brought into contact with the

点があつた。 In the conventional gate valve as described above, after the valve desk 2 moves laterally toward the valve seat 1 and comes into contact with the valve seat 1, the reaction force causes the valve stopper 3 to move.
is pressed against the valve outer casing 18, and large friction is generated between the valve casing 18 and the valve stopper 3, which moves in the radial direction of the valve desk 2, resulting in a loss of extrusion force.

る。 In the present invention, in order to eliminate such drawbacks, a groove 1 is provided on the back surface of the valve stopper 3 as shown in FIGS. 3 and 4.
6 is formed, and a roller 1 is formed between this groove 16 and the valve outer casing 18.
7, and the roller 17 is always restrained downward within the groove 16 by the spring 19.

プリングである。 In addition, 12 is a roller, 14 is a roller receiver, 13 is a wall extending upwardly formed on the end face of this roller receiver, 15
is a return spring that connects the roller receiver 14 and the roller 12.
本考案はゲートバルブにおいては上記のように

滑油が蒸発してしまう真空中においても弁の開閉
動作を容易に且つ確実になし得る大きな利益があ
る。 In the gate valve of the present invention, the roller 12 is inserted between the valve stopper 3 and the valve outer casing 18 as described above, so that there is no galling or friction between the two, and even in a vacuum where lubricating oil evaporates. There is a great advantage that the valve can be opened and closed easily and reliably.
