Problems solved by technology

Therefore, for different nominal sizes of discharge ports, it is necessary to prepare correspondingly different sizes of vulcanization molds, which will lead to increased costs and reduced flexibility
Furthermore, the sealing ring can only be held in place on the wall by means of a holder in the form of an angle profile on the side of the wall, which is structurally complex and also disadvantageous in terms of installation technology

Embodiment Construction

[0027] figure 1 The reference numeral 2 in the figure designates a wall in which an outlet 3 of a channel not shown in detail is arranged. A shutter device 26 is provided for selectively closing the outlet 3 . The gate device 26 is fixed on the wall body 2 through a frame not specified in detail, and includes a shaft (valve rod) 4 and a gate 10 that can move vertically with the shaft 4, and the gate is used to close the gate as required. Outlet 3 of wall 2.

[0028] The shutter device 26 comprises a frame strut 12 on both sides of the shutter 10 in which the shutter 10 is guided vertically. Only in the region of the wedge-shaped structures 13, 14 to be explained below, in figure 1 The frame struts 12 are shown interrupted for better understanding.

[0029] In order to ensure the seal between the shutter 10 and the wall 2 , the shutter device 26 includes a sealing ring 1 which is mounted on the wall side in the region of the outlet 3 , as will be explained in more detail be...

Abstract

The present invention relates to a double side acting ring (1) in a valve device which is fixed in an area of a wall body with an outlet for closing the outlet. The sealing ring has a sealing body with two sealing parts (5, 6), and a frame with frame parts (7, 8) for carrying the sealing body, where the sealing parts exhibit different material hardness and / or elastic characteristics. The frame is arranged at an external side of the sealing body, which has an extension (11) formed by two parts, where the frame is connected with the extension. The extension is arranged between the frame parts, and the sealing parts are connected with each other over a partial area of contact surfaces of the sealing parts.

Description

technical field [0001] The invention relates to a double-acting sealing ring according to the preamble of claim 1 . Background technique [0002] A corresponding sealing ring is known from DE 196 21 248 B4. The sealing ring disclosed in this patent document comprises a steel ring encapsulated by two different rubber materials in a vulcanization process. Therefore, for different nominal sizes of discharge ports, it is necessary to prepare vulcanization molds of different sizes accordingly, which will lead to an increase in cost and a decrease in flexibility. Furthermore, the sealing ring can only be held in place on the wall by means of a holder in the form of a wall-side corner profile, which is structurally complex and also disadvantageous in terms of installation technology. Contents of the invention [0003] The object of the present invention is to provide a new sealing ring of this type which is simple and economical to produce and at the same time ensures simplifie...
