Problems solved by technology

[0004] However, the known pipes have the disadvantage that the sealing element can slip out of the separation point, thereby causing a leak
This increases assembly costs
Furthermore, liquid or gaseous toxic media may escape during operation of the plant including the pipeline and may constitute a hazard for the plant user

Embodiment Construction

[0025] figure 1 A cross-sectional view of the end of one pipe is shown. exist figure 1 The cross-sectional views shown in may relate to the ends of straight or curved pipes or may relate to T-pieces, Y-pieces, four-branched pipes, six-branched pipes or other elements known per se for constructing pipe networks of a single connector.

[0026] The pipe 10 has a longitudinal section 13 with a substantially constant wall thickness and a parallel outer contour. The longitudinal section 13 serves either to convey the fluid flowing in the interior of the pipe 10 in a straight line or to move the figure 1 Adapt the fittings at the ends shown in to one of the piping elements described above.

[0027] The first longitudinal section 13 merges with a second longitudinal section 16 into the carrier 100 . The inner and / or outer walls of the second longitudinal section 16 may be inclined outwardly relative to the first longitudinal section 13 by a small number of degrees. This results ...

Abstract

The invention relates to a pipe connection device (30) for connecting a first pipe (10) made of glass with a second pipe made of glass, the first pipe having a ball disc ( 100) and the second conduit has a ball (160) as part of the connection system, wherein the ball disc has an inner sealing surface (110) and an outer sealing surface (120) which are inclined inwardly, wherein the inner sealing surface and the outer sealing surface Separated from each other by a step (130), an elastic sealing element (20) having a ring-shaped basic shape is arranged between the ball disc and the ball (160), the sealing element having an upper side (222) arranged adjacent to the ball and with the ball disc The lower side (221) adjacent to the sealing surface of (100) is characterized in that a protruding partial surface (25) is formed on the upper side and / or lower side of the sealing element, the inner sealing surface of the ball disc and the outer sealing surface The surfaces each have a concave shape, wherein the inner sealing surface has a larger radius of curvature than the outer sealing surface.

Description

technical field [0001] The invention relates to a pipe connection device. Background technique [0002] Pipes and sealing elements can be used, for example, in chemical technology and / or in the pharmaceutical industry for conveying gaseous or liquid media. [0003] Pipes are known from practice which have sealing flanges on at least one end, so that several pipes can be joined by associated connecting elements. To ensure the tightness of the connection, a sealing element made of elastic material can be inserted between the sealing flanges of the pipe. [0004] However, the known pipes have the disadvantage that the sealing element can slip out of the separation point, resulting in leakage. This increases the assembly outlay. Furthermore, liquid or gaseous toxic media can escape during operation of the plant including the lines and can constitute a hazard for the user of the plant. Contents of the invention [0005] It is therefore the object of the present invention to...
