Utilize accompanying drawing that the utility model is described further, but the embodiment in the accompanying drawing does not constitute any restriction to the utility model.

Fig. 1 is the utility model schematic representation.

Fig. 2 is the utility model sectional view.

Fig. 3 is that the utility model is analysed and observe partial enlarged drawing.

Fig. 4 is the utility model sealing schematic representation.

In Fig. 1, Fig. 2, Fig. 3, Fig. 4, comprise:

1, limited wheel, 2, vacuum vessel, 3, conducting orifice, 4, cylinder, 5, the Gate-valve sealing plate; 6, fixed plate, 7, compress voussoir, 8, the gate valve seat board, 9, Stamping Steel Ribbon; 10, compress guide wheel, 11, the reseat pressure spring, 12, linear rail, 13, the sealing load spring.

Embodiment

Below in conjunction with embodiment the utility model is elaborated.

Among Fig. 1, Fig. 2, Fig. 3, Fig. 4, above vacuum vessel 2 inwall conducting orifices 3, be provided with limited wheel 1, conducting orifice (3) both sides are provided with linear rail 12; Be provided with cylinder 4 in vacuum vessel 2 bottom outer wall, cylinder 4 push rods pierce into vacuum vessel 2 inside, and these cylinder 4 push rod ends have been provided with gate valve seat board 8; Be fixedly connected with gate valve fixed plate 6 on one side at gate valve seat board 8, this gate valve fixed plate 6 is provided with and compresses voussoir 7; Gate valve seat board 8 another sides are provided with reseat pressure spring 11, and these reseat pressure spring 11 upper end supporting surfaces are supported with Gate-valve sealing plate 5, and said Gate-valve sealing plate 5 and linear rail 12 movable blocks connect and to take turns 1 position corresponding with fixed limit; Gate-valve sealing plate 5 connects with fixed plate 6 through sealing load spring 13 and bolt and nut and is close to, and on Gate-valve sealing plate 5, is provided with Stamping Steel Ribbon 9, compresses guide wheel 10; Saidly compress guide wheel 10 and compress voussoir 7 corresponding matching; Said Stamping Steel Ribbon 9 is corresponding with vacuum vessel 2 inner wall positions.

The said voussoir 7 that compresses is provided with one section control and compresses the plane of inclination that guide wheel 10 compresses displacement.

The said voussoir 7 that compresses is fastened on the fixed plate 6 through screw.

Vacuum vessel 2 inside are in communication with the outside through the conducting orifice on the vacuum vessel 23;, vacuum vessel 2 needs first confined bed port 3 when need carrying out vacuumizing; Cylinder 4 actions promote gate valve seat board 8 and rise, and the Gate-valve sealing plate 5 that is installed on the gate valve seat board 8 rises with the fixed plate 6 of support on reseat pressure spring 11 synchronously; Because the spring force effect of sealing load spring 13, Gate-valve sealing plate 5 keeps being close to state with fixed plate 6.When Gate-valve sealing plate 5 rose the arrival precalculated position, Gate-valve sealing plate 5 contacted with limited wheel 1, and limited wheel 1 stops Gate-valve sealing plate 5, was installed in the fixed plate 6 that promotes on the gate valve seat board 8 and then continued to rise.At this moment; Gate-valve sealing plate 5 begins to produce the dislocation displacement with fixed plate 6; Reseat pressure spring 11 is compressed; Gate-valve sealing plate 5 and fixed plate 6 be close to compact heap 7 top incline in the face groove with compress guide wheel 10 mutual extrusion, Gate-valve sealing plate 5 overcomes the active force of sealing load spring 13, to vacuum vessel 2 inwall displacements.When cylinder push-rod arrives predetermined stroke, the 5 complete and vacuum vessel 2 inwalls applyings of Gate-valve sealing plate, 9 pairs of conducting orifice 3 peripheries of Stamping Steel Ribbon seal fully, and whole seal closure operation is accomplished.Otherwise then open vacuum chamber conducting orifice 3, vacuum chamber and outside conducting.

Should be noted that at last; Above embodiment is only in order to the technological scheme of explanation the utility model but not to the restriction of the utility model protection domain; Although the utility model has been done detailed description with reference to preferred embodiment; Those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technological scheme of the utility model, and do not break away from the essence and the scope of the utility model technological scheme.
