Tube coupling
First Claim
1. A tube coupling for the detachable coupling of tube line sections in a high-pressure tubing system, comprising:
- a pair of coupling blocks one of which one has a coupling plug and the other of which has a plug socket for receiving the coupling plug, the coupling blocks including side flanges held together by a clamping screw; and
a sealing ring arranged at a front face of the coupling plug, the sealing ring being supported by a protective socket enclosing the sealing ring and the coupling plug, the protective socket including portions adjacent to a rear end of the protective socket, the portions defining a circumferential sealing lip provided and engaged between the coupling blocks circumferentially around the coupling plug.

Abstract
A tube coupling for the detachable coupling of tube line sections of a high-pressure tubing system. The tube coupling includes two coupling blocks held together by a clamping screw, whereby one of the coupling blocks has a coupling plug that engages a plug socket provided on the other coupling block. A sealing ring is formed of a plastically deformable material and is enclosed between a front face of the coupling plug and a bottom-side sealing surface of the plug socket. In order to protect the sealing ring from being lost, damages and/or contaminated during assembly or opening and dosing the coupling, in a preassembled condition it is enclosed within a protective socket. To homogeneously load the sealing ring, the sealing ring is located at one point of a supporting triangle, the two other supporting points of being formed by a pair of supporting surfaces arranged side by side at an outer end of side flanges of the coupling blocks.

-
a pair of coupling blocks one of which one has a coupling plug and the other of which has a plug socket for receiving the coupling plug, the coupling blocks including side flanges held together by a clamping screw; and a sealing ring arranged at the front face of the coupling plug, the sealing ring being supported by a protective socket enclosing the sealing ring and the coupling plug; wherein at least one of the side flanges includes a step defining two partial surfaces engaging the other of the at least one of the side flanges, the partial surfaces located adjacent to an outer end of the at least one of the side flanges, the partial surfaces being separated by a recessed portion therebetween so that the partial surfaces together with a sealing arrangement to form a symmetrical supporting triangle, whereby the clamping screw is provided in the region of the center of the triangle and an axis of the tube lines and an axis of the clamping screw run in a common plane. - View Dependent Claims (13, 14, 15, 16)
