Abstract

A vacuum valve with a valve housing with a valve opening, a closing element, and at least one peripherally closed seal on the closing element with first and second seal main sections and first and second seal connecting sections allocated to corresponding seat main sections and connecting sections. The seal extends in a groove defined by two side walls and a base wall. The first seal main section is arranged on a front end face of the closing element and has a middle part where the seal extends in a straight line. The seal is clamped by a clamping bar at least across part of the middle part, with the clamping bar fixed on the closing element and forming one of the side walls. Through at least one second sub-region of the longitudinal extent of the seal, the two side walls and base wall are formed by the closing element.

Dependent claims

Vacuum valve comprising:

a valve housing with a valve opening that has an axis,
a valve seat that surrounds the valve opening and has a first seat main section and a second seat main section;
the first and second seat main sections being arranged offset relative to each other in a direction of the axis of the valve opening and being connected to each other by first and second seat connecting sections;
a closing element that is moveable in a straight line in a closing direction extending at an angle to the axis of the valve opening from an open position in which the valve opening is exposed into a closed position in which the valve opening is sealed and against the closing direction from the closed position into the open position;
first and second peripherally closed seals that are arranged on the closing element and each have first and second seal main sections and first and second seal connecting sections allocated to the first and second seat main sections and the first and second seat connecting sections;
each of the peripherally closed seals extends in a respective groove that are each bounded, viewed in cross section, by two side walls and one base wall;
the first seal main sections are arranged on a front end face of the closing element with respect to the closing direction and each has a respective middle part in which each of the seals extends in a straight line;
the first and second seals are each clamped by a clamping bar at least across a first sub-region of a longitudinal extent thereof lying in the middle part of the respective first seal main sections;
the clamping bar is fixed on the closing element and forms one of the two side walls of the corresponding groove;
and
the two side walls and the base wall defining the corresponding groove are formed by the closing element across at least a second sub-region of the longitudinal extent of each of the seals.

a closing element that is moveable in a straight line in a closing direction extending at an angle to the axis of the valve opening from an open position in which the valve opening is exposed into a closed position in which the valve opening is sealed and against the closing direction from the closed position into the open position;
at least one peripherally closed seal that is arranged on the closing element and has first and second seal main sections and first and second seal connecting sections allocated to the first and second seat main sections and the first and second seat connecting sections and extends in a groove that is bounded, viewed in cross section, by two side walls and one base wall;
the first seal main section is arranged on a front end face of the closing element with respect to the closing direction and has a middle part in which the seal extends in a straight line;
the seal is clamped by a clamping bar at least across a first sub-region of a longitudinal extent thereof lying in the middle part of the first seal main section, wherein the clamping bar is fixed on the closing element and forms one of the two side walls of the groove;
the two side walls and the base wall defining the groove are formed by the closing element across at least a second sub-region of the longitudinal extent of the seal;
and
a peripherally closed seat seal is arranged on the valve seat, the seat seal is pressed onto the associated seal on the closing element across an entire longitudinal extent in the closed position of the closing element without a belt guided through the valve opening and extends in a seat-seal groove that has two side walls and one base wall.
