Abstract
The utility model relates to a safe connecting structure for large-sized high-pressure flanges, which is characterized in that a pipe connector is connected into a flange, one end of the pipe connector is provided with a cylindrical head, after the cylindrical head is mounted in the flange, the other end of the pipe connector is exposed out of the flange, the root of the pipe connector exposed out of the flange is welded on the flange, the tail of the end of the pipe connector is connected with a pipe on a pipeline, a 'U'-shaped weld joint used for being welded with the flange and a pen point shaped gap used for weakening welding stress are sequentially disposed between the top of the cylindrical head and the flange, and contact surfaces of the bottom surface of the cylindrical head of the pipe connector and the flange are hermetically connected. The safe connecting structure is reasonable in design, simple and practical, not only changes breakage generation portions, but also greatly reduces leakage flow area after breakage, provides a secondary sealing structure after breakage, further reduces leakage quantity after breakage, gains time for taking remedial measures, and has the advantages of reducing accidental damage, having safety operation and quite convenient use and the like.
Description
Technical field
It is inflammable that the utility model belongs to high pressure, and the flange of explosive medium pipe connects, particularly a kind of safe connection structure of large-scale high pressure flange.
Background technique
At present, inflammable at high pressure, during the flange of explosive medium pipe connects, with the large-sized flange of pipeline be connected adopt band neck welding neckflanges as high pressure equipment such as hydrogenators more and connect, the weakness of its connection is the circular weld position that is connected with pipe at flange, and the circular weld position that whole pipe connects when superpressure destruction occurring can disconnect, make whole pipe be in open state fully, its dielectric leakage amount is very big, and Ji is dangerous, can cause enormous economic loss again.
Summary of the invention
The utility model is intended to the shortcoming and defect part that exists in above-mentioned technology, the safe connection structure of a kind of large-scale high pressure flange with safety protection function is provided, this safe connection structure is not only reasonable in design, simple and practical, Ji has changed the happening part of rupture failure, thereby reduces post-rift leak flow area significantly, and a secondary seal structure is provided after fracture again, further reduced post-rift leakage rate, gained time for adopting remedial measures; And having the minimizing accident harm, handling safety and use very just wait characteristics.
The purpose of this utility model is to adopt following technological scheme to realize: the safe connection structure of described large-scale high pressure flange, comprise flange, it is characterized in that: at flange inner connection tube connecting head, one end of described pipe connector is provided with socket cap, with the hole that is provided with this socket cap of packing in position, shape and the big or small corresponding flange of described socket cap, after treating in this socket cap load hole, the other end of pipe connector stretches outside flange, and its end pipe last and on the pipeline is connected; One end of described pipe connector is provided with socket cap, with the hole that is provided with this socket cap of packing in position, shape and the big or small corresponding flange of described socket cap, after treating in this socket cap load hole, the other end of pipe connector stretches outside the flange, will stretch the root weld of the outer pipe connector of flange on flange; Along being provided with " U " shape weld seam of flange welding usefulness between the top of described socket cap and the flange in regular turn and weakening the pencil point-shaped slit that welding stress is used; Between the socket cap bottom surface of pipe connector and the surface of contact of flange or by directly being tightly connected of two surface of contact, or being tightly connected of the sealing gasket of packing into.
The root weld intensity of described pipe connector should be less than the weld strength on the pipe on pipe connector and the pipeline.
Principle of the present utility model and operation are described below: owing to installed the pipe connector that is welded to connect that bears shearing stress in the utility model, the weld strength of this pipe connector need be lower than the intensity of circular weld on the pipe on it and the pipeline, use and form expection destruction position, also be provided with a secondary seal structure between the socket cap bottom surface of pipe connector and the surface of contact of flange, further reduced or eliminated post-rift leakage rate, gained time for adopting remedial measures.
Combine the above technological scheme of being taked, realize the purpose of this utility model.Compared with prior art, the utility model is not only reasonable in design, simple and practical, Ji has changed the happening part of rupture failure, reduce post-rift leak flow area again significantly, and a secondary seal structure is provided after fracture, and further reduced post-rift leakage rate, gain time for adopting remedial measures; And having the minimizing accident harm, handling safety and use very just wait characteristics.
