Abstract
The invention discloses a pipe fitting capable of storing a cold material in a turn up edge. The pipe fitting comprises a pipe body, the pipe body is provided with a left-to-right pass-through inner chamber, a path is integrally formed in the middle part of the inner chamber, the inner edge of the path is provided with a turn up edge extending to both the left side and the right side, and a clearance is reserved between the turn up edge and the side wall of the inner chamber so as to form an annular groove. The pipe fitting provided by the invention has the advantages of low probability of blockage and better discharge capacity.
Description
Technical field
The present invention relates to link technical field, especially relate to a kind of plastic pipe storing flange cold burden.
Background technique
Along with popularizing of PP-R (random copolymer of ethene) tubing, PP-R pipe fitting is able to a large amount of employing.Usually, the inner chamber of PP-R pipe fitting is smooth shape and is provided with a latus rectum in the middle part of inner chamber.In use, the inwall of pipe fitting and the outer surface of tubing are linked together by the mode of hot melt, and latus rectum serves the effect of the insertion depth of location tubing.Its defect is: latus rectum, after being heated, very easily causes its internal diameter diminish or even block.
Summary of the invention
For the deficiency that above-mentioned prior art exists, the object of this invention is to provide a kind of plastic pipe storing flange cold burden, it has not easily blocking, water-flowing amount preferably feature.
To achieve these goals, the technical solution adopted in the present invention is: the plastic pipe can storing flange cold burden, comprise body, this body has the penetrating inner chamber in left and right, and the integral middle of this inner chamber forms a latus rectum, the inner edge of described latus rectum has the flange all carrying out extending in both sides to the left and right, has gap thus form annular groove between this flange and this intracavity sidewall.
The minimum width of described annular groove is 4mm.
The inwall of described inner chamber is provided with the material reducing groove of left and right trend.
Described pipe fitting is the preparation of PP-R material.
Adopt after said structure, the present invention compared to the prior art advantageously: not easily block, water-flowing amount be better.The latus rectum place storing the plastic pipe of flange cold burden of the present invention has flange thus forms annular groove, and the cold burden after sweat soldering can be stored at wherein by this annular groove, thus ensure that latus rectum has the internal diameter of setting all the time, then not easily blocks.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is the perspective cross-sectional schematic diagram of embodiments of the invention 1;
Fig. 2 is the front sectional view of embodiments of the invention 2;
Fig. 3 is the right elevation of Fig. 2;
Fig. 4 is the A portion enlarged view of Fig. 3.

30, annular groove.
Embodiment
Embodiment 1
As shown in Figure 1, can store the plastic pipe of flange cold burden, comprise body 10, this body 10 has the penetrating inner chamber in left and right 11, and the integral middle of this inner chamber 11 forms a latus rectum 20.So-called latus rectum 20, popular saying is exactly the step of the annular extended internally set by the middle part of this inner chamber 11, and the internal diameter at this step place is less than the diameter of this inner chamber 11.
Further say, the inner edge of this latus rectum 20 has the flange 21 all carrying out extending in both sides to the left and right, has gap thus form annular groove 30 between this flange 21 and this inner chamber 11 sidewall.According to measuring and calculating, the minimum width of this annular groove 30 is preferably 4mm.Like this, the cold burden after sweat soldering can be stored at wherein by this annular groove 30, ensure that this latus rectum 20 place has suitable internal diameter all the time.
This pipe fitting is the preparation of PP-R material, and it can adopt precise injection molding mode to make.Certainly, this pipe fitting also can adopt the inserts of propylene and PP-R material or HPb59-1 material to make through precise injection molding technique.
Embodiment 2
See shown in Fig. 2 to Fig. 4, be only with the difference of embodiment 1: the inwall of this inner chamber 11 is provided with the material reducing groove 12 moved towards left and right.Like this, by reducing the production of hot melt cold burden, guarantee that this latus rectum 20 has suitable internal diameter further.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
