Abstract
The invention relates to the field of liquid delivery pipelines, in particular to a hose with a metal framework inside. The buckle type framework hose consists of the framework and an organic material, wherein the organic material wraps the framework; the framework consists of a row of annular lapping pieces which are connected to one another end to end; the front of each lapping piece is a lapping head while the rear of each lapping piece is a lapped head; each lapping head is in lap joint with the corresponding lapped head in a matched manner; and after each lapping head is in lap joint with the corresponding lapped head, a certain axial movement gap is formed between each lapping head and the corresponding lapped head. The framework in the buckle type framework hose consists of the row of the annular lapping pieces which are connected to one another end to end, when the hose is stretched or bent, the lapping pieces can extend by a certain degree, when the organic material of the hose is stretched to an extremity degree, hooks at the fronts and the rears of the lapping pieces can be hooked to each other, and a large tensile strength is provided, so that the hose cannot be broken. While a supporting force is provided for the hose, the tensile property of the hose is greatly improved.
Description
Technical field
The present invention relates to liquid transmission pipeline field, particularly relate to a kind of flexible pipe including metal frame.
Background technique
Organic flexible pipe of various liquid such as conveying water, oil etc. is in order to meet the requirement of intensity and bending properties, usually be all that built-in metal skeleton forms in organic material flexible pipe, the existing flexible pipe including skeleton as shown in Figure 1, comprise skeleton 1 and organic material 2, skeleton 1 is wrapped in organic material 2, skeleton 1 is all coil spring shape, not only can play the effect supporting organic material, bear and come from the pressure of carried liquid and the pressure of external agency, organic flexible pipe can also be made can to have flexible performance under maintenance cross-sectional configuration prerequisite.
But be through Long-Time Service to find, the skeleton of this type is made flexible pipe and is had certain problem, helical spring skeleton resistance to tension is poor, do not limit exceeding the extraneous tensile force of elastic force, organic like this flexible pipe is when being subject to the stretching of single pulling force or overbending, helical spring part area may exceed elastic strain scope, and final flexible pipe is pulled off or cannot recovers after being out of shape.Such as, marine oil transportation flexible pipe, under the effect of huge seawater unilateral thrust, after spiral metal skeleton is unrestrictedly elongated, organic hose material will be pulled off, and oil will leak into marine greatly, causes an immeasurable loss.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of hasp type skeleton flexible pipe, skeleton in this flexible pipe is made up of the ring-type fastener member of the mutual snapping of row's ending, when the organic material of flexible pipe is stretched to the limit, gib head before and after fastener member can hook mutually, suitable stretching resistance is provided, thus ensure that flexible pipe is not pulled off, while providing support power for flexible pipe, also greatly strengthen the tensility of flexible pipe.
The present invention is achieved in that a kind of hasp type skeleton flexible pipe, be made up of skeleton and the organic material enveloping skeleton, described skeleton is formed by the bridge piece overlap joint that joins end to end of row's annular, the front portion of bridge piece is lap joint, rear portion is overlapped head, lap joint matches with overlapped head and overlaps, and after overlap joint, lap joint and overlapped head have and necessarily move axially gap.
Described bridge piece Central Symmetry.
Described lap joint comprises front boss and front slide concave surface, described overlapped head comprises rear boss and rear slip concave surface, the protrusion direction of described front boss and rear boss is contrary, when lap joint and overlapped head overlap mutually, front boss is enclosed within outside rear slip concave surface, rear boss is enclosed within outside front slide concave surface, and the axial width of front boss and rear boss is less than the axial width of rear slip concave surface and front slide concave surface.
Described skeleton is metal frame.
Skeleton in hasp type skeleton flexible pipe of the present invention is made up of the ring-type fastener member of the mutual snapping of row's ending, when flexible pipe is stretched or is bending, fastener member can carry out elongation to a certain degree, when the organic material of flexible pipe is stretched to the limit, gib head before and after fastener member can hook mutually, suitable stretching resistance is provided, thus ensures that flexible pipe is not pulled off, while providing support power for flexible pipe, also greatly strengthen the tensility of flexible pipe.
Accompanying drawing explanation
Fig. 1 is the existing schematic cross-section including the flexible pipe of skeleton;
Fig. 2 is the schematic cross-section of hasp type skeleton flexible pipe of the present invention;
Fig. 3 is the structural representation of bridge piece in the present invention.
In figure: slide after 1 skeleton, 2 organic materials, 3 bridge pieces, 4 lap joints, 5 overlapped heads, 41 front boss, 42 front slide concave surfaces, 51 rear boss, 52 concave surface.
Embodiment
Below in conjunction with specific embodiment, set forth the present invention further.Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's statement.
Embodiment 1
As shown in Figure 2,3, a kind of hasp type skeleton flexible pipe, be made up of skeleton 1 and the organic material 2 enveloping skeleton 1, described skeleton 1 is formed by bridge piece 3 overlap joint that joins end to end of row's annular, the front portion of bridge piece 3 is lap joint 4, rear portion is overlapped 5, and lap joint 4 matches with overlapped 5 and overlaps, and after overlap joint, lap joint 4 has necessarily move axially gap with overlapped 5.
Conveniently in production and processing, bridge piece 3 has the function overlapping with front unit and overlapped by rear unit simultaneously, usually bridge piece 3 is arranged to centrosymmetric shape, arrange in turn can complete when installing bridge piece 3 like this, need not be positive and negative in differentiation, simplify production and processing and spare part work.
In the present embodiment, described lap joint 4 comprises front boss 41 and front slide concave surface 42, described overlapped 5 comprises rear boss 51 and rear slip concave surface 52, the protrusion direction of described front boss 41 and rear boss 51 is contrary, when lap joint 4 overlaps mutually with overlapped 5, front boss 41 is enclosed within outside rear slip concave surface 52, and rear boss 51 is enclosed within outside front slide concave surface 42, and the axial width of front boss 41 and rear boss 51 is less than the axial width of rear slip concave surface 52 and front slide concave surface 42; When flexible pipe extends within the specific limits or be bending, boss will slide axially on slip concave surface, and when being stretched to the limit, the inwall of front and back boss will hook mutually, makes skeleton 2 can not unconfined elongation or bending, guarantees that flexible pipe can not be pulled off.
In the present invention, in order to take into account the demand of toughness and intensity, described skeleton 1 is generally metal frame, but does not also get rid of and use the high-quality high molecular polymerization materials and parts that can meet performance requirement as framework material.
