Description
Technical field
The utility model relates to PE pipe fitting fields in drainage system, more particularly, to a kind of pressure-bearing down stream tee joint.
Background technique
Currently, the PE pipe fitting in existing building drainage system, according to CJT 250-2007 " used in construction drainage high-density polyethylene
Alkene (HDPE) tubing and pipe fitting " standard, it need to be done under 80oC water temperature 165 hours, the hydrostatic strength of 4.6MPa does not rupture, is not permeable
Leakage；Because that there is integral strengths is inadequate for pipe fitting in the threeway on existing market, the sharp corner especially in intersection position can be produced
During raw stress is strong, when stress concentration degree reaches the limit suffered by material, failure rupture will occur for plastic pipe, lead to leak
Occur, it is more serious or even safety accident can be caused.Meet performance purpose to reach, the general practice is to increase wall thickness, but increase
Wall thickness is added to will increase cost, and wall thickness is too thick is unfavorable for and tubing welding.
Utility model content
The utility model in order to overcome at least one of the drawbacks of the prior art described above, provides a kind of pressure-bearing down stream tee joint,
The utility model intensity is enough, and tube burst drainage is avoided to occur.
In order to solve the above technical problems, the technical solution adopted in the utility model is: a kind of pressure-bearing down stream tee joint, including the
One bellmouth, the second bellmouth and third bellmouth, first bellmouth are connected with third bellmouth, the second bellmouth and the first bellmouth side
Connection, first bellmouth and the second bellmouth inner hole are connected by arc section, first bellmouth and the second bellmouth outer surface
Infall has a circle protruding reinforcing rib.The effect of arc section is can be water along going down, without to flowing backwards inside branch pipe.When
It is overboard to be just shot back in standpipe again when the water of standpipe upstream falls on the arc section between branch pipe and standpipe, so that riser interiors
Water energy is enough smoothly to fall, and is unlikely to enter branch pipe upstream.Because occurring at leak to be all infall, therefore reinforcing rib can be effective
Enhance weak ring, keeps away the generation of this tube burst drainage.In addition to this, reinforcing rib can reinforce the first bellmouth and the second bellmouth
Bonding strength, mitigate the negative effect of water impact, while making up the rigidity failures of injection molding part.
Further, first bellmouth and the second bellmouth centerlines a are 91 ° -92 °, preferably 91.5 °, are made
Second bellmouth upward, so that water will not enter the second bellmouth.
Further, the bore of first bellmouth is greater than or equal to the bore of the bore of third bellmouth, the second bellmouth.
Further, 1 bore of the first bellmouth is 110mm, and the bore of the second bellmouth and third bellmouth is 50mm,
One of 75mm or 110mm.
Further, expansion mouth is equipped on the end of first bellmouth, the second bellmouth and third bellmouth.Expansion mouth
Hot melt processing is carried out with the assembly side of corresponding water-drainage tube part, later inserts water-drainage tube part through hot melt treated assembly side
Enter in corresponding expansion mouth, be connected as one later by natural cooling, so can guarantee higher bonding strength and connection
Leakproofness.It can be facilitated by expansion mouth and carry out assembly connection with water-drainage tube part, promote applicability.
Further, second bellmouth and the first bellmouth junction are raised equipped with water conservancy diversion close to third bellmouth one end.
By water conservancy diversion protrusion standpipe downstream can be led water to, water is avoided to enter Zhi Shangyou in standpipe upland water.
Further, the water conservancy diversion protrusion is at a distance from the first socket axis less than the radius of the first bellmouth.Water conservancy diversion is convex
It rises and is protruded relative to the first bellmouth hole wall, play the role of obstructing water flow.
Compared with prior art, beneficial effect is: the utility model can smoothly guide water flow, avoid occurring in branch pipe
Portion's water conservancy diversion, in addition the design of reinforcing rib can effectively enhance weak ring, keep away the generation of this tube burst drainage.
Detailed description of the invention
Fig. 1 is the utility model schematic cross-sectional view；
Fig. 2 is the utility model monnolithic case structural schematic diagram.
Specific embodiment
The attached figures are only used for illustrative purposes and cannot be understood as limitating the patent；In order to better illustrate this embodiment, attached
Scheme certain components to have omission, zoom in or out, does not represent the size of actual product；To those skilled in the art,
The omitting of some known structures and their instructions in the attached drawings are understandable.Being given for example only property of positional relationship is described in attached drawing
Illustrate, should not be understood as the limitation to this patent.
As shown in Figure 1, a kind of pressure-bearing down stream tee joint, including the first bellmouth 1, the second bellmouth 2 and third bellmouth 3, it is described
First bellmouth 1 is connected with third bellmouth 3, and the second bellmouth 2 is connected to 1 side of the first bellmouth, in the first bellmouth 1 and the second bellmouth 2
Hole is connected by arc section 21, and first bellmouth 1 and 2 outer surface infall of the second bellmouth have a circle protruding reinforcing rib 22.Circle
The effect of segmental arc 21 is can be water along going down, without to flowing backwards inside branch pipe.When the water of standpipe upstream falls on branch pipe
It is overboard to be just shot back in standpipe again when arc section 21 between standpipe, it smoothly falls so that the water energy of riser interiors is enough, and it is unlikely
In entrance branch pipe upstream.Because occurring at leak to be all infall, therefore reinforcing rib 22 can effectively enhance weak ring, keep away this pipe fitting
