Abstract
A pipe is provided for transporting a viscous fluid, including a pressure relief valve provided with a sealing element which separates the inside of the pipe from a discharge line and is designed to release the discharge line in the event of predetermined excess pressure. A surface of the sealing element, facing a Miler chamber of the pipe, is associated with the pipe in such a manner that the surface is flown around by a flow of the viscous fluid circulating through the pipe when in operation, and the sealing element is fixed in the closed position by a rod, the rod being displaced by the predetermined excess pressure such that the thus connected sealing element releases the discharge pipe.
Claims14
A pipe for transporting a viscous fluid, comprising:
- a pressure relief valve including a body and a sealing component, said pressure relief valve separates an interior of the pipe from an outflow pipeline and unblocks the outflow pipeline in the event of a predetermined overpressure, said sealing component including a disc and a seal attached to said disc that forms a seal with said body, a face of the sealing component is arranged in the pipe through which the fluid flows, wherein the face of the sealing component facing the interior of the pipe is shaped to generally conform to the contour of the inner side of the pipe wall and faces the interior of the pipe and is flush with an inside surface of a wall of the pipe such that the face is rinsed by the viscous fluid during operation, wherein the sealing component is fixed in the closed position by a linkage, and said linkage is displaced by the predetermined overpressure, so that the sealing component connected thereto moves away from the wall of the pipe and unblocks the outflow pipeline.
A pipe for transporting a viscous fluid, comprising:
- a pressure relief valve including a body and a sealing component, wherein said pressure relief valve separates an interior of the pipe from an outflow pipeline and unblocks the outflow pipeline in the event of a predetermined overpressure in the pipe,
- said sealing component including a disc and a seal attached to said disc that forms a seal with said body, a face of said sealing component faces the interior of the pipe and is flush with an inside surface of a wall of the pipe through which the fluid flows, wherein the face of the sealing component facing the interior of the pipe is shaped to generally conform to the contour of the inner side of the pipe wall and is rinsed by the viscous fluid of the pipe during operation;
- and
- a buckling rod attached to said sealing component, wherein said buckling rod is configured to bend or buckle in the event of the predetermined overpressure, wherein said sealing component is fixed in a closed position by said buckling rod, and said buckling rod is displaced to a second position by the predetermined overpressure, causing the sealing component to move away from the wall of the pipe and unblock the outflow pipeline.
