Abstract
The utility model discloses a downstream three-way pipe. The downstream three-way pipe is characterized by comprising a main pipe and a branch pipe which are made of PVC materials, the branch pipe is arranged in the middle of the main pipe, the branch pipe is communicated with the main pipe into an integral structure, the inner wall of the main pipe and the inner wall of the branch pipe are respectively provided with a sand spraying layer, the branch pipe is sleeved with a casing pipe, the end of the branch pipe extends out of the port of the casing pipe, connecting ribs are arranged between the inner wall of the casing pipe and the outer wall of the branch pipe, and the outer side wall of the main pipe and the outer side wall of the end of the casing pipe are respectively provided with an annular positioning boss. The downstream three-way pipe is reasonable in structural design; the inner wall of the main pipe and the inner wall of the branch pipe are provided with the sand spraying layers, the water can flow slowly, and therefore the effect of lowering noise is achieved; by means of the structural design of the casing pipe outside the branch pipe, the bearing capability of the branch pipe can be enhanced, the pressure of part of water can be borne for the branch pipe, and the service life of the branch pipe can be prolonged; by means of the annular positioning boss design, the overall structure can be fixed and installed conveniently while the strength is increased.
Description
Technical field
The utility model relates to pipeline field, relates in particular to a kind of down stream tee joint pipe.
Background technique
Down stream tee joint is a kind of pipe fitting in discharge pipe line, vertical connection for arm and main, although be vertical connection, but arm enters the joint of main and does not intersect vertically, but connect by a bit of circular arc flow direction downstream, so just make the water of arm flow to main very smoothly, this bit of circular arc is exactly to have played effect downstream.Existing down stream tee joint tubular construction is simple, and its noise producing in process is downstream large, and its arm mostly adopts single layer structure, is easily subject to water pressure and is out of shape or damages after its long-term use, affects its working life.
Model utility content
The purpose of this utility model is in order to make up the deficiency of prior art, and a kind of down stream tee joint pipe is provided.
The utility model is achieved through the following technical solutions:
A kind of down stream tee joint pipe, it is characterized in that: include the main and the arm that adopt PVC material to make, described arm is arranged on the middle part of main, and the formula that is communicated as one with it structure, the inwall of described main and arm is respectively equipped with sandblast layer, and described arm is set with sleeve pipe outward, and the oral area of sleeve pipe is stretched out in the end of arm, between the inwall of described sleeve pipe and arm outer wall, be provided with connecting tendon, on the outer side wall of described main and cannula tip, be respectively equipped with circular orientation boss.
The utility model has the advantages that:
The utility model reasonable in design, the inwall of main and arm is provided with sandblast layer, can slow down flowing of water, thereby reach the effect that reduces noise, by the structural design of the sleeve pipe outside arm, can strengthen the ability to bear of arm, auxiliary branch line is born the pressure of a part of water, improve its working life, by the design of circular orientation boss, when gaining in strength, facilitate integrally-built fixing and installation.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Referring to accompanying drawing, a kind of down stream tee joint pipe, include the main 1 and the arm 2 that adopt PVC material to make, arm 2 is arranged on the middle part of main 1, and formula structure that is communicated as one with it, and the inwall of main 1 and arm 2 is respectively equipped with sandblast layer 3, the outer sleeve pipe 4 that is set with of arm 2, and the oral area of sleeve pipe 4 is stretched out in the end of arm 2, between the inwall of sleeve pipe 4 and arm 2 outer walls, be provided with connecting tendon 5, on the outer side wall of main 1 and sleeve pipe 4 ends, be respectively equipped with circular orientation boss 6.
