Abstract
A sealing system for a shutoff element having two substantially ring-shaped sealing elements forming at least two substantially ring-shaped sealing lines. A given one of the sealing elements is constructed as a thin-wall body which is elastically deformable under the action of a closing force. The given sealing element, in the closed position of the shutoff element, under deformation of its wall bearing against the other sealing element at least at two ring regions with line contact. Means define free deformation spaces for the wall of the thin-wall body beneath said ring regions, and means define a respective support adjacent said deformation spaces and extending substantially parallel to the ring regions and against which bears said wall.
Claims19
A sealing system for a shutoff element comprising
- housing and blocking members of the shutoff element,
- an annular metallic sealing element extending between said housing and blocking members and sealingly connected to one of said members,
- said annular sealing element having a thin walled portion which is elastically deformable under a closing force between said housing and blocking members and extends through an annular width of said sealing element,
- at least two annular supporting areas on each of said housing and blocking members which under the closing force make sealing linear contact with and deform said thin walled portion of said sealing element,
- and free spaces for deformation of said thin walled portion therein, under the maximal closing force, on opposite sides of said thin walled portion from each of said annular supporting areas and enclosed by said thin walled portion and said other member than said member making the linear contact at the annular supporting area,
- said annular supporting areas adjacent each of said free spaces for deformation, and said spaces on a member extending substantially parallel to said supporting areas on said same member.
A method of producing a shutoff in a sealing system comprising the steps of
- moving a blocking member relative to a housing member along a closing axis,
- pressing and deforming a deformable thin wall body sealingly between said blocking member and said housing member along at least two annular supporting areas on each of said housing and blocking members into free spaces on opposite sides of said thin wall body from said annular supporting areas with a force that substantially exceeds a prescribed closing force for the shutoff in the sealing system.
