Abstract
The utility model discloses a solid wall spiral pipe, which comprises a pipe body, wherein the inner wall of the pipe body is provided with a plurality of continuous spiral type pipe ribs, the pipe ribs comprise pipe rib roots close to the inner wall of the pipe body and pipe rib tops far away from the inner wall of the pipe body, the pipe rib roots are symmetrically provided with first arc sections, and the surface of the pipe rib tops is a second arc section connecting the two first arc sections; a solid-wall spiral pipe is characterized in that through the structural design of R1 angle circular arc sections on two sides of the root of a pipe rib, impact stress concentration is relieved, and impact energy is dispersed; the impact performance of the solid-wall spiral pipe completely meets the national standard requirement; in addition, through the structural design of pipe rib top R2 angle circular arc section, hang foul and impurity easily after avoiding the damaged top closed angle, reduced the risk that the pipeline is stifled, more scientific and practical.
Description
Technical Field
The utility model relates to a relevant technical field of tubular product particularly, relates to a real wall spiral pipe.
Background
At present, the tube rib of the existing solid-wall spiral tube is integrally in an inverted triangle shape with a sharp corner, so that the tube rib is easy to crack from the sharp corner at the root part of the spiral rib when an impact test is carried out, and impact stress concentration cannot be buffered and impact energy cannot be dispersed; the impact performance can not completely meet the national standard requirement after the national standard impact test is failed; in addition, in the long-term use, the sharp corner at the top of the existing spiral rib is very easy to damage, and dirt and impurities are easily hung after the sharp corner is damaged, so that the risk that the pipeline is blocked is increased.
SUMMERY OF THE UTILITY MODEL
To the above technical problem in the related art, the utility model provides a real wall spiral pipe can overcome prior art's the aforesaid not enough.
In order to achieve the technical purpose, the technical scheme of the utility model is realized as follows:
The utility model provides a real wall spiral pipe, includes the body, the body inner wall is equipped with a plurality of continuous spiral type ribs, the rib include with the rib root that is close to the body inner wall and keep away from the rib top of body inner wall, rib root bilateral symmetry is equipped with first circular arc section, rib top surface is for connecting two the second circular arc section of first circular arc section.
Further, the distance between each two adjacent tube ribs is equal.
Further, the number of the pipe ribs is 4-12.
Further, the radius R1 of the first circular arc section is 5-6 mm.
Further, the radius R2 of the second circular arc segment is 0.5 mm.
The utility model has the advantages that: the utility model provides a solid wall spiral pipe, which reduces the impact stress concentration and disperses the impact energy through the structural design of the R1 angle circular arc sections on the two sides of the root part of the pipe rib; the impact performance of the solid-wall spiral pipe completely meets the national standard requirement; in addition, through the structural design of pipe rib top R2 angle circular arc section, hang foul and impurity easily after avoiding the damaged top closed angle, reduced the risk that the pipeline is stifled, more scientific and practical.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required to be used in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
FIG. 1 is a schematic view showing the structure of a conventional spiral pipe;
Fig. 2 is a schematic structural diagram of a solid-walled spiral pipe according to an embodiment of the present invention.
In the drawings: 1: a pipe body, 2: tube rib, 21: tube rib root, 22: the tube rib top.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.
As shown in fig. 1-2, according to the embodiment of the present invention, a solid spiral pipe includes a pipe body 1, wherein the inner wall of the pipe body 1 is provided with a plurality of continuous spiral type pipe ribs 2, the pipe ribs 2 include a pipe rib root 21 close to the inner wall of the pipe body 1 and a pipe rib top 22 far away from the inner wall of the pipe body 1, the pipe rib root 21 is bilaterally symmetrical and provided with a first arc segment, and the surface of the pipe rib top 22 is a second arc segment connecting the two first arc segments.
In this embodiment, the distances between two adjacent tube ribs 2 are equal.
In the embodiment, the number of the tube ribs 2 is 4-12.
in this embodiment, the radius R1 of the first arc segment is 5mm to 6 mm; wherein the diameter of the pipe body isAndWhen the first arc segment is in the shape of a circle, the radius R1 of the first arc segment is 5 mm; in the diameter of the tube bodyThe radius R1 of the first circular arc segment is 6 mm.
In this embodiment, the radius R2 of the second circular arc segment is 0.5 mm.
Specifically, in the requirements of the national standard impact test, no fracture is qualified after 10 times of impact and 9 times of impact; under the condition of same pipe diameter, the prior spiral pipe has 4 times of rupture in 10 times of national standard impact tests; the spiral pipe of the application has no fracture for 10 times in 10 times of national standard impact tests, and completely meets the requirements of the national standard; simultaneously, the structure of the second arc section of the R2 angle at the top of the pipe rib reduces the damage in the specific use process, greatly reduces the phenomenon that dirt and impurities are easily hung after a certain part of the original sharp-angle structure is damaged, and reduces the risk of blocking the pipeline.
To sum up, the utility model relates to a solid-wall spiral pipe, which reduces the impact stress concentration and disperses the impact energy through the structural design of the R1 angle arc sections at the two sides of the root of the pipe rib; the impact performance of the solid-wall spiral pipe completely meets the national standard requirement; in addition, through the structural design of pipe rib top R2 angle circular arc section, hang foul and impurity easily after avoiding the damaged top closed angle, reduced the risk that the pipeline is stifled, more scientific and practical.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
