Abstract

A valve ( 1 ), in particular a vacuum valve, with at least one closure member ( 2 ) which has a wedge-shaped closure region ( 3 ), and with at least one valve seat ( 5 ) which surrounds a valve opening ( 4 ) of the valve ( 1 ), wherein, in a closed position of the closure member ( 2 ), the wedge-shaped closure region ( 3 ) bears sealingly against the valve seat ( 5 ) and closes the valve opening ( 4 ) and, in an open position, opens up the valve opening ( 4 ) so that fluids and/or solids can be transported through the valve opening ( 4 ), wherein the closure member ( 2 ) with the wedge-shaped closure region ( 3 ) is mounted so as to be movable back and forth between the closed position and the open position along a movement path ( 6 ), wherein the movement path ( 6 ) is angled-off and/or bent.

First claim

The invention claimed is:

1. A valve comprising:
at least one closure member having a wedge-shaped closure region,
at least one valve seat surrounding a valve opening of the valve,
the at least one closure member being movable between a closed position in which the wedge-shaped closure region lies against the at least one valve seat in sealing fashion and closes the valve opening and an open position in which the at least one closure member frees the valve opening for at least one of fluids or solids to be transported through the valve opening,
the at least one closure member with the wedge-shaped closure region is mounted for movement back and forth on a movement path between the closed position and the open position, and the movement path is at least one of angled or curved,
at least one slide path for guiding the at least one closure member along the movement path, and the at least one slide path includes a first slide path section that is at least one of angled or curved relative to a second slide path section,
wherein the at least one closure member further comprises a wedge-shaped passage region which surrounds a transfer opening in the at least one closure member,
in the open position, the at least one closure member bears with the passage region in sealing fashion against the at least one valve seat, and in the open position the transfer opening of the at least one closure member for the through transportation of at least one of fluids or solids is arranged in alignment with the valve opening, and
the movement path has a central movement path section and two movement path sections which are connected in each case to ends of the central movement path section, and the movement path sections which are connected in each case at ends thereof to the central movement path section are in each case arranged at an angle relative to the central movement path section.

2. The valve as claimed in claim 1 , further comprising at least one roller or at least one slider for guiding the at least one closure member along the movement path, and the roller or the slider is guided by the at least one slide path.

3. The valve as claimed in claim 1 , wherein at least one of the movement path or the at least one slide path is angled.

4. The valve as claimed in claim 1 , wherein in each case two successive movement path sections of the movement path enclose an angle of 135° to 170°.

5. The valve as claimed in claim 1 , wherein the movement path is curved along an entire length thereof.

6. The valve as claimed in claim 1 , further comprising a valve housing, and the at least one valve seat is part of the valve housing.

7. The valve as claimed in claim 6 , wherein the transfer opening is surrounded by a transfer opening limiting wall of the passage region of the at least one closure member in order to prevent penetration of the at least one of fluids or solids into an interior of the valve housing.

8. The valve as claimed in claim 7 , wherein the closure region of the at least one closure member and the passage region of the at least one closure member are permanently rigidly connected to each other.

9. The valve as claimed in claim 7 , wherein the at least one closure member has in each case at least one seal or at least one seal seat in the closure region and in the passage region.

10. The valve as claimed in claim 1 , further comprising at least one of a linear drive or swivel drive for moving the at least one closure member back and forth between the open position and the closed position.

11. The valve as claimed in claim 10 , wherein the linear drive and the at least one closure member are connected to each other by at least one transmission lever, and the transmission lever is arranged to be swivelable on both the linear drive and the at least one closure member.

12. The valve as claimed in claim 1 , wherein the valve is a vacuum valve.

13. A valve comprising:
at least one closure member having a wedge-shaped closure region,
at least one valve seat surrounding a valve opening of the valve,
the at least one closure member being movable between a closed position in which the wedge-shaped closure region lies against the at least one valve seat in sealing fashion and closes the valve opening and an open position in which the at least one closure member frees the valve opening for at least one of fluids or solids to be transported through the valve opening,
the at least one closure member with the wedge-shaped closure region is mounted for movement back and forth on a movement path between the closed position and the open position, and the movement path is at least one of angled or curved,
at least one slide path for guiding the at least one closure member along the movement path, and the at least one slide path includes a first slide path section that is at least one of angled or curved relative to a second slide path section,
wherein the at least one closure member further comprises a wedge-shaped passage region which surrounds a transfer opening in the at least one closure member,
in the open position, the at least one closure member bears with the passage region in sealing fashion against the at least one valve seat, and in the open position the transfer opening of the at least one closure member for the through transportation of at least one of fluids or solids is arranged in alignment with the valve opening,
wherein the at least one slide path has a central slide path section and two slide path sections which are connected in each case to ends of the central slide path section, and the slide path sections which are connected in each case at ends thereof to the central slide path section are in each case arranged at an angle relative to the central slide path section.

14. The valve as claimed in claim 13 , wherein in each case two successive slide path sections of the at least one slide path enclose an angle of 135° to 170°.
