Fluid line
Technical field
The present invention relates to connection set, be specifically related to fluid line.
Background technique
Fluid line is generally connected with another segment pipe or equipment by connection inserting part, and existing connection inserting part is generally cylindric, on the side that is connected one end with pipeline, has annular recess, has rectangular recess on end face.Annular recess for preventing the seepage of fluid, can prevent that connection inserting part from coming off in fluid line on the one hand on the other hand; Rectangular recess is mainly used in preventing that connection inserting part from rotating relative to fluid line.Pipeline generally only casts in the outside of connection inserting part, and two adjacent segment pipes are not directly connected.
The shortcoming of existing connection inserting part is that annular recess position easily produces crack in Vehicle Processing process, later use is brought to potential safety hazard, and annular recess prevents that the effect of fluid leaks is general, the combination of connection inserting part and pipeline neither be very firm, and the two easily produces seepage and comes off in the time of bending.
Summary of the invention
Technical problem to be solved by this invention is that solution fluid line is insecure, easily produces the problem of seepage.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is to provide a kind of fluid line, comprise pipeline and the connection inserting part that is fixed on described pipeline one end, described connection inserting part is cylindric, the top cover of described connection inserting part has fastening piece, on the inwall of described connection inserting part bottom, be fixed with multiple projections, on the side of described connection inserting part lower end, have several through holes radially, the upper end of described pipeline overlays on by teeming ladle on the interior outer side wall of described connection inserting part, the internal surface top end face of described pipeline is concordant with the top end face of described connection inserting part, the outer surface top end face of described pipeline is lower than the top end face of described connection inserting part.
In above-mentioned fluid line, described projection is circumferential uniform along described connection inserting part.
In above-mentioned fluid line, described projection is horizontal sheet, and its top is arc.
In above-mentioned fluid line, described through hole is rectangle.
In above-mentioned fluid line, described through hole is triangle.
In above-mentioned fluid line, the material of described pipeline is atactic copolymerized polypropene, and the material of described connection inserting part is stainless steel.
It is one-body molded that connection inserting part provided by the invention and device for cleaning pipeline are crossed casting, and pipeline is coated on the interior outer side wall of connection inserting part, two adjacent segment pipes can directly be connected, projection on connection inserting part and through hole can more firmly be combined as a whole it with pipeline, the two is not easy to come off and produce seepage.
Brief description of the drawings
Fig. 1 is the structural representation of fluid line provided by the invention;
Fig. 2 is the structural representation of connection inserting part provided by the invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
As shown in Figure 1, fluid line provided by the invention, comprise pipeline 1 and the connection inserting part 2 that is fixed on pipeline 1 top, connection inserting part 2 is cylindric, pipeline 1 is one-body molded by casting with connection inserting part 2, the material of pipeline 1 is atactic copolymerized polypropene (PPR), and the material of connection inserting part 2 is stainless steel, and pipeline 1 and connection inserting part 2 can be also other universal materials certainly.
On the inwall of connection inserting part 2 bottoms, be fixed with six projections 21, projection 21 is circumferential uniform along connection inserting part 2, and projection 21 is horizontal sheet, and its top is arc.Projection 21 is just embedded in the tube wall of pipeline 1 afterwards in casting, can prevent relatively moving of pipeline 1 and connection inserting part 2, makes the connection of the two more firm.
On the side of connection inserting part 2 lower ends, have at random several through holes 22 radially, through hole 22 is irregularly shaped, and in the present embodiment, through hole 22 has two, be respectively a rectangle with one leg-of-mutton.
The upper end of pipeline 1 overlays on by teeming ladle on the interior outer side wall of connection inserting part 2, the internal surface top end face 12 of pipeline 1 is concordant with the top end face of connection inserting part 2, the outer surface top end face 11 of pipeline 1 is lower than the top end face of connection inserting part 2 and higher than through hole 22, conventionally the height of outer surface top end face 11 is at 1/2nd to 2/3rds places of connection inserting part 2, raw material were so both saved, again through hole 22 is cast in pipeline 1, through hole 22 can increase the soundness of the two connection, prevents relatively rotating and coming off of connection inserting part 2; The part that connection inserting part 2 exposes pipeline 1 can put fastening piece (not shown), the fastening piece that present embodiment adopts is internal thread loose joint cap, because the height of the inwall 12 of pipeline 1 is identical with the height of connection inserting part 2, pipeline 1 can directly be resisted against on its end face in the time being connected with another segment pipe, fixedly tighten by fastening piece again, can effectively prevent the seepage of fluid, because connection inserting part 2 is thinner, inwall 12 parts in connection inserting part 2 can play to it effect of bracing reinforcement on the other hand.
Connection inserting part provided by the invention 2 processing are simple, can the darker grooves of Vehicle Processing, and manufacturing efficiency is high, and product is difficult for producing crack, and whole course of working can not impact quality of product, and later use is not had to potential safety hazard, safe and reliable.
Connection inserting part 2 provided by the invention is one-body molded by casting with pipeline 1, and pipeline 1 is coated on the interior outer side wall of connection inserting part 2, two adjacent segment pipes can directly be connected, projection 21 on connection inserting part 2 and through hole 22 can more firmly be combined as a whole it with pipeline 1, the two is not easy to come off and produce seepage.
The present invention is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present invention, and every have identical or close technological scheme with the present invention, within all falling into protection scope of the present invention.
