Background technology
The periphery wall of existing pipe fitting is rounded, and in order to reach certain intensity requirement, then the wall thickness of pipe fitting is typically set
Put thicker, particularly, in the crooked position of pipe fitting, in order to strengthen the structural strength at position, the thickness of crooked position also needs to
Thicken.Although thicker tube wall can improve to a certain extent pipe fitting intensity, material wave inevitably be present
Take, cause the material cost of pipe fitting to increase.
The content of the invention
In view of this, the purpose of this utility model is to provide a kind of novel pipe fitting, and it is strong can not only to improve fitting structure
Degree, and consumptive material is less.
To reach above-mentioned purpose, the utility model provides following technical scheme：
A kind of novel pipe fitting, including pipe fitting body, the periphery wall profile bag that the pipe fitting body intercepts on radial section
At least three arcs that annular is uniformly arranged are included, are connected between adjacent two arcs provided with straightway, and it is all
The arc and straightway are tangent with an auxiliary circle, and the auxiliary circle and the pipe fitting body are coaxial, and the camber line
The radius of curvature of section is more than the radius of curvature of the auxiliary circle.
Further, the pipe fitting body includes bending section, and the plane of symmetry of the bending section hangs down with wherein described straightway
Directly.
Further, the both ends of the bending section are provided with straight length, two sections of straight lengths positioned at the bending section both ends
Between angle be more than or equal to 90 ° and less than 180 °.
Further, the pipe fitting body is three-way pipe or right-angle elbow pipe.
Further, the pipe fitting body is straight tube.
Further, 2-5 times of the radius of curvature of the arc equal to the radius of curvature of the auxiliary circle.
The beneficial effects of the utility model are：
Novel pipe fitting of the present utility model, by setting segmental arc and straight line on the radial direction profile of the periphery wall in pipe fitting
Section, in this way, cambered surface and plane can be formed outside auxiliary circle, formed between intersecting cambered surface and plane and strengthen bulge-structure, energy
Enough structural strengths for effectively strengthening pipe fitting, i.e., by using the pipe fitting of the structure, radius between auxiliary circle and pipe fitting internal diameter it
Difference can be set smaller, and relied primarily on the reinforcement structure between cambered surface and plane and played booster action, not increase pipe fitting
Under conditions of wall thickness, play the technical purpose of enhancing pipe fitting structural strength, and the consumptive material of pipe fitting is less, can it is effectively save into
This.

Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, so that those skilled in the art
The utility model can be better understood from and can be practiced, but illustrated embodiment is not as to restriction of the present utility model.
As shown in figure 1, the structural representation for the utility model novel pipe fitting embodiment.The novel pipe fitting of the present embodiment,
Including pipe fitting body 1, the periphery wall profile that the pipe fitting body 1 intercepts on radial section includes annular be uniformly arranged at least
Three arcs 2, straightway 3 is provided between adjacent two arcs 2 and is connected, and all arcs 2 and straight line
Section 3 is tangent with an auxiliary circle 4, and the auxiliary circle 4 and the pipe fitting body 1 are coaxial, and the radius of curvature of the arc 2
More than the radius of curvature of the auxiliary circle 4, specifically, arc 2 and the inscribe of auxiliary circle 4.In this way, the cambered surface 6 that arc 2 is molded
The plane 7 formed with straightway 3, which intersects to be formed outside pipe fitting body 1, strengthens bulge-structure 5, plays and strengthens pipe fitting structural strength
Technical purpose.The annular of segmental arc 2 of the present embodiment is uniformly arranged as 4, as needed, the quantity of segmental arc 2 is arranged to 5
And more than 5 can also realize technical purpose.
Further, the pipe fitting body 1 includes bending section, and the plane of symmetry of the bending section and wherein described straightway 3
Vertically.
Further, the both ends of the bending section are provided with straight length, two sections of straight lengths positioned at the bending section both ends
Between angle be more than or equal to 90 ° and less than 180 °, i.e. pipe fitting body can be three-way pipe, as shown in Figure 2, or right angle
Bend pipe, as shown in Figure 3, or general elbow, as shown in Figure 4.The novel pipe fitting body 1 of the present embodiment is three-way pipe.When
So, according to being actually needed, for pipe fitting body 1 it can also be provided that straight tube, its principle is identical, is not repeated.
Further, the radius of curvature of the arc 2 is equal to 2-5 times of the radius of curvature of the auxiliary circle 4, the present embodiment
