Abstract
The utility model relates to the field of tube stock, in particular to a special-shaped three-way tube. The special-shaped three-way tube comprises a straight tube (6) and a branch tube (4) and is characterized in that the straight tube (6) and the branch tube (4) are welded with the two ends of a reinforcement tube (5); the outer diameter of the reinforcement tube (5) is larger than that of the branch tube (4) while the inner diameter of the reinforcement tube (5) is equal to that of the branch tube (4), and the thickness of the reinforcement tube (5) is larger than that of the branch tube (4), therefore, compared with the joint of a general three-way tube, the joint of the special-shaped three-way tube has higher strength and stronger welding angle stress and is not easy to fracture; an elbow tube (3) is in acute angle or obtuse angle connection with the branch tube (4), so as to overcome the defect that the original single branch tube (4) can not span obstruction; and polyurethane thermal insulation layers (2) and an outer protecting tubes (1) are wrapped outside the straight tube (6), the branch tube (4) and the elbow tube (3), so as to form the thermal insulation three-way tube. For the three-way tube, the structure design is reasonable, the conception is ingenious and novel, the safety and the reliability are good, the manufacturing cost is low, the using effect is good, and the three-way tube is easy for large-scale promotion and application.
Description
Technical field
The utility model relates to the tubing field, and what be specifically related to is a kind of profiled tee joint pipe fitting.
Background technique
At present, tee pipe fitting on the market is made up of three-way straight pipe, tee branch, wherein the port of tee branch has flange plate, the interface of tee branch part can only match with flange, interface is single, because it is more frivolous that three-way straight pipe is connected with arm, weld the angle stress difference, tear easily during use etc. and Accident due to quality to occur.
The model utility content
In order to overcome the deficiency in the background technique, the utility model provides a kind of profiled tee joint pipe fitting, and this profiled tee joint pipe fitting has solved the problem of straight tube and arm easy-rupturing, reasonable in design, and the novelty that is skillfully constructed, safe and reliable, low cost of manufacture.
In order to solve the problem that has straight tube and arm easy-rupturing in the background technique, the utility model is by the following technical solutions: a kind of profiled tee joint pipe fitting, comprise straight tube, arm, it is characterized in that: straight tube and arm are welded on the two ends of reinforcement tube, the external diameter of reinforcement tube is greater than arm, and internal diameter equates that bend pipe acutangulates with arm or the obtuse angle is connected.
The beneficial effects of the utility model are: the profiled tee joint fitting structure is reasonable in design, and the novelty that is skillfully constructed is safe and reliable, low cost of manufacture, and using effect is good, and is easy to large-scale promotion application.
Description of drawings:
Accompanying drawing 1 is the structural representation of profiled tee joint pipe fitting.
Among the figure: the outer protective tube of 1-; The 2-polyurethane insulation coating; The 3-bend pipe; The 4-arm; The 5-reinforcement tube; The 6-straight tube.
Embodiment:
Referring to accompanying drawing; this embodiment is by the following technical solutions; a kind of profiled tee joint pipe fitting comprises straight tube 6, arm 4; it is characterized in that: straight tube 6 and arm 4 are welded on the two ends of reinforcement tube 5; the external diameter of reinforcement tube 5 is greater than arm 4, and internal diameter equates that the thickness of reinforcement tube 5 is greater than arm 4; thereby than common threeway joint intensity height; welding angle stress is good, and welding angle stress is good, not easy-rupturing; bend pipe 3 acutangulates with arm 4 or the obtuse angle is connected; can overcome the drawback that original single arm 4 can not leaping over obstacles like this, at straight tube 6; arm 4 and bend pipe 3 exterior packages are provided with polyurethane insulation coating 2 and outer protective tube 1, can make the tee pipe fitting of insulation; reasonable in design; the novelty that is skillfully constructed, safe and reliable, low cost of manufacture; using effect is good, and is easy to large-scale promotion application.
Claims (1)
1. a profiled tee joint pipe fitting comprises straight tube (6), arm (4), it is characterized in that: straight tube (6) and arm (4) are welded on the two ends of reinforcement tube (5), the external diameter of reinforcement tube (5) is greater than arm (4), and internal diameter equates that bend pipe (3) acutangulates with arm (4) or the obtuse angle is connected.
