Abstract
The utility model relates to a pipeline quick joint which is especially suitable for connections between pipelines with medium-diameter or large-diameter and belongs to the technical field of pipeline connections. The technical scheme includes that the pipeline quick joint comprises a flexible connecting pin (9), an outer sleeve (10) and an inner sleeve (7), wherein the outer sleeve (10) is matched with the inner sleeve (7). An annular flexible connecting pin channel is arranged on a surface where the outer sleeve is matched with the inner sleeve. A flexible connecting pin mounting hole (11) is arranged on the outer sleeve and is communicated with the annular flexible connecting pin channel. The annular flexible connecting pin channel is matched with the flexible connecting pin. The pipeline quick joint solves the problem of slow mounting speed of the pipeline with medium-diameter or large-diameter, particularly when a water inrushing accident happens in a mine, connections of two pipelines can be achieved within 20 to 30 seconds, precious time is provided for dealing with an emergency, and injuries and deaths of personnel are reduced.

Description
Technical field
The utility model relates to a kind of pipeline fast joint, and the connection in being specially adapted between the major diameter pipeline belongs to pipeline interconnection technique field.
Background technique
At present, in industry, be used widely, require pipeline to connect fast under a lot of situation greater than the middle major diameter pipeline more than the 100mm; For example: when water leak accident appears in mine, fixedly mount emergency drainage equipment and pipeline work fast, the quality time is provided for speedily carrying out rescue work; Can reduce personnel's injures and deaths; The speed that connects between two pipelines, under the prerequisite of ensuring the quality of products with intensity, The faster the better.In the background technique, general flange plate, bolt and the rubber pad etc. of adopting are connected between the pipeline, with reference to accompanying drawing 1, mainly are to be connected by flange plate 3, rubber pad 4, bolt 2, nut 5, packing ring 6, also have and adopt the method for directly welding to connect.There is following problem in above-mentioned two kinds of Placements: workmen's labor intensity is big, and high to operator's technical merit requirement, it is slow that pipeline is installed connection speed, and inefficiency couples together two middle major diameter pipelines, generally needs more than half an hour.
The model utility content
The utility model purpose provides a kind of pipeline fast joint, and the quick connection in the realization between the major diameter pipeline is raised the efficiency, and reduces labor intensity, solves the problems referred to above that exist in the background technique.
The technological scheme of the utility model is:
Pipeline fast joint; The overcoat and the interior cover that comprise flexible attachment pegs, mate each other; The face that overcoat and interior cover cooperatively interact is provided with annular flexible attachment pegs passage; Be provided with flexible attachment pegs mounting hole on the coat, with the flexible attachment pegs channel connection of annular, annular flexible attachment pegs passage and flexible attachment pegs are complementary.
The described pin that flexibly connects is made up of wire rope and a plurality of rigidity shear sleeve, and a plurality of rigidity shear sleeves penetrate in the wire rope, and it is flexible to flexibly connect pin, adapts to the shape of annular flexible attachment pegs passage.Said rigidity shear sleeve is a plurality of metal short tubes, and the diameter of the diameter of metal short tube and annular flexible attachment pegs passage is complementary, and the length of metal short tube confirms that according to the tortuosity of the flexible attachment pegs passage of annular tortuosity is bigger, and the length of metal short tube is shorter; Tortuosity is less, and the length of metal short tube is longer, makes that flexibly connecting pin can insert annular flexible attachment pegs passage.
The flexible attachment pegs passage of described annular is to be combined by the circular groove of overcoat internal surface and the circular groove of lining the outer surface of; The flexible attachment pegs passage of annular can form a complete annulus, also can be a plurality of loop configuration of helical, can also be incomplete annulus.
Put outward a flexible attachment pegs mounting hole can be set,, flexible attachment pegs mounting hole more than two also can be set on the coat, with being communicated with of a flexible attachment pegs passage of annular with whole a connection of the flexible attachment pegs passage of annular.
Many the flexible attachment pegs passages of annular also can be set between interior cover and overcoat, be communicated with a plurality of flexible attachment pegs mounting hole that puts setting outward respectively, every one of flexible attachment pegs passage coupling of annular flexibly connects pin.
The utility model also is provided with seal arrangement, and for example the O RunddichtringO overlaps between the overcoat in being arranged on; Install the O RunddichtringO earlier interior putting, interior cover is fit into overcoat, guarantee the sealing effect that pipeline connects.
The utility model also is provided with sealing cover, is complementary with flexible attachment pegs mounting hole, will flexibly connect after pin inserts annular flexible attachment pegs passage through flexible attachment pegs mounting hole, through the flexible attachment pegs mounting hole sealing of sealing cover with sleeve surface.
Use the utility model, connection procedure is following: the end of two pipelines that need connect is the overcoat and the interior cover of fixed tube road rapid pipe joint respectively, then interior cover is inserted overcoat; Flexible attachment pegs is inserted annular flexible attachment pegs passage interior cover and overcoat between through the flexible attachment pegs mounting hole that puts outward, accomplish the connection work of two pipelines.
The utility model good effect: the utility model has solved the slow problem of middle major diameter pipeline installation rate; When especially water leak accident appears in mine; Can fixedly mount emergency drainage equipment and pipeline work fast, the quality time is provided for speedily carrying out rescue work, can reduce personnel's injures and deaths; The utility model can also solve long pipe runs because of the pipeline length change problem that temperature variation causes, need not install the pipeline slip joint again additional; The utility model can be accelerated the installment work of emergency drainage pipeline, makes the pipeline installation rate improve tens times, and the general 20-30 of the connection of two pipelines just can accomplish second.The utility model bears high pressure after can also making pipeline that connection is installed, and keeps sealing, and the ability load-bearing, and flexible attachment pegs can be born the shearing force more than 800 tons.
