Abstract
The utility model relates to a pipeline, in particular to an oval tube. The oval tube is characterized in that the cross section of the oval tube takes an oval shape, and the oval cross section comprises a big head section, a small head section and a transition section, wherein the circular arc curvature radius of the big head section is larger than that of the small head section, and the curve of the transition section adopts rounding off with the big head section and the small head section to form a closed tube wall. Since the oval tube is provided with a big upper part and a small lower part when being installed for use, when the same flow quantity of sewage water is delivered, by comparing with the circular tube with equivalent inner diameter, the water at the tube bottom can still be kept in a certain depth when the water flow in the tube is very limited, and the foreign impurities can flow away along with the water rather than be deposited at the tube bottom; therefore, the oval tube can always ensure smooth interior water flow under any waster flow condition; and the oval tube can be widely used for the buried drainage field.
Description
Technical field
The utility model relates to a kind of pipeline, particularly a kind of avette pipe.
Background technology
As everyone knows, present most pipeline all is a circular pipe, this pipeline is easy to processing, but in the blowdown application scenario of current inequality, because current are very little sometimes, it is many to contain dirty composition, cause impurity sedimentation and accumulation easily, in the course of time, can cause line clogging, or reduce ducted flow characteristics because of deposition.
Summary of the invention
The purpose of this utility model is that a kind of avette pipeline that all has good flow characteristics under any flow condition will be provided.
For achieving the above object, the technical solution of the utility model is: a kind of avette pipe, it is characterized in that this pipe cross section is avette, this oval cross section comprises three parts, major part section, microcephaly's section and changeover portion, major part section circular arc radius of curvature is greater than the circular arc radius of curvature of microcephaly's section, and the curve of changeover portion and major part section and microcephaly's section rounding off form closed tube wall.Because avette piping erection is up big and down small when using, and when carrying the sewage of same flow, compares with the circular pipe of suitable internal diameter, when ducted current are very little, water still can keep certain depth at the pipe end, and impurity can flow away with water, is difficult for being deposited in the pipe end.Thereby avette pipeline can both guarantee that water flow inside is unimpeded under any flow condition.
The outstanding advantage that the utility model relates to is: during avette line transportation sewage, flow characteristics is good, and impurity is difficult for piling up and stops up, and can be widely used in the buried pollution discharge field.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Specific embodiments
As shown in Figure 1, a kind of avette pipe, its cross section is avette, this oval cross-section comprises three parts, major part section (1), microcephaly's section (2) and changeover portion (3), major part section (1) circular arc radius of curvature is greater than the circular arc radius of curvature of microcephaly's section (2), the curve of changeover portion (3) and major part section (1) and microcephaly's section (2) rounding off form closed tube wall.Use when installing, microcephaly's section (2) is laid down.In the buried pollution discharge application, when ducted current were very little, water still can keep certain depth at the pipe end, and impurity can flow away with water, is difficult for being deposited in the pipe end.
Claims (2)
1, a kind of avette pipe is characterized in that this pipe cross section is avette.
2, avette pipe as claimed in claim 1, it is characterized in that this pipe oval cross-section comprises three parts, major part section (1), microcephaly's section (2) and changeover portion (3), major part section (1) circular arc radius of curvature is greater than the circular arc radius of curvature of microcephaly's section (2), the curve of changeover portion (3) and major part section (1) and microcephaly's section (2) rounding off form closed tube wall.
