Description

Technical Field

[0001] The utility model relates to the field of pipelines, in particular to a double-rib spiral pipe. Background Art

[0002] The inner wall of the double-rib spiral tube has two spiral ribs with a certain pitch and height. The function of the spiral ribs is to make the water flowing down the tube wall form a spiral wall-attached water flow, reduce the falling speed of the water flow, and increase the friction resistance of the tube wall.

[0003] Due to the limited width of the spiral ribs, when the drainage in the pipe exceeds the handling limit of the spiral ribs, the water will flow over the outer edge of the spiral ribs and fall down;

[0004] To this end, there are methods such as setting spiral ribs with large inclination angles or expanding the width of the spiral ribs to increase the processing upper limit. However, based on the setting process of the above improvement methods, most of the effects are obtained after adjusting the size of the spiral ribs. Therefore, this application is based on the spiral ribs of original size and proposes a double-rib spiral tube that optimizes the processing upper limit of the spiral ribs by only changing the shape. Utility Model Content

[0005] The utility model aims to provide a double-rib spiral pipe to solve the above technical problems.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A double-rib spiral tube comprises a tube, wherein the inner wall of the tube is provided with two spiral ribs coinciding with the axis of the tube, wherein any one of the two spiral ribs is a mirror image of the other spiral rib;

[0008] The surface of each spiral rib is provided with at least two grooves sunken into the spiral rib, and ribs for spacing the grooves are provided between the grooves.

[0009] Preferably, the spiral rib has an extension portion, and a channel is provided in the extension portion.

[0010] Preferably, the junction between the extension portion and the spiral rib has a rounded corner that rises upward toward the extension portion.

[0011] Preferably, the end surfaces of the spiral ribs and the extension are flush with the end of the tube.

[0012] The beneficial effects of the utility model are:

[0013] 1. In the utility model, the surface of the spiral ribs for contacting the liquid is provided with a first groove sunken into the spiral ribs and a second groove adjacent to the first groove. The first groove and the second groove can expand the surface area of ​​the spiral ribs for contacting the fluid and increase the upper limit of the spiral ribs for treating the fluid.

[0014] 2. The spiral ribs in the present invention also have extensions, and the joints with the spiral ribs have rounded corners that rise toward the extensions. The rounded corners actually form grooves with accommodating spaces on the spiral ribs, further expanding the upper limit of the fluid handling capacity of the spiral ribs.

[0015] 3. The utility model provides a channel in the extension part, and the channel is combined with a colored liquid poured into the channel to judge whether the spiral ribs in the pipe and the adjacent pipe are successfully connected. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0022] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings.

[0023] Example 1

[0024] In this embodiment, a double-ribbed spiral tube is proposed. Figure 1 and Figure 2 The main body of the double-rib spiral tube includes a tube 1 and two spiral ribs 2 coinciding with the axis of the tube 1. Specifically, one of the spiral ribs 2 is a mirror image of the other spiral rib 2, that is, the two spiral ribs 2 are fixed on the inner wall of the tube 1 in a facing manner. Figure 1 The best use effect can be achieved when it is in the upright position as shown.

[0025] See also Figure 2 The arrow indicates an enlarged view, in which a first groove 3 and a second groove 4 adjacent to the first groove 3 are provided on the surface of the spiral rib 2 for contacting the liquid, wherein a rib for spacing the grooves is provided between the first groove 3 and the second groove 4. It is further explained that the first groove 3 and the second groove 4 are grooves sunken into the spiral rib 2. Therefore, the purpose of providing the first groove 3 and the second groove 4 is to expand the surface area of ​​the spiral rib 2 for contacting the fluid, thereby expanding the upper limit of the spiral rib 2 for treating the fluid.

[0026] Please continue reading Figure 2 The arrow points to the enlarged view, in which the spiral rib 2 also has an extension, and the junction with the spiral rib 2 has a rounded corner that is upward toward the extension. In this way, combined with the upward rounded corner, the upper limit of the spiral rib 2 to process fluid is further expanded, limiting the fluid from crossing the spiral rib 2.

[0027] Example 2

[0028] In this embodiment, a double-ribbed spiral tube is proposed. Figure 1 and Figure 2 The main body of the double-rib spiral tube includes a tube 1 and two spiral ribs 2 coinciding with the axis of the tube 1. Specifically, one of the spiral ribs 2 is a mirror image of the other spiral rib 2, that is, the two spiral ribs 2 are fixed on the inner wall of the tube 1 in a facing manner. Figure 1 The best use effect can be achieved when it is in the upright position as shown.

[0029] See also Figure 2 The arrow indicates an enlarged view, in which a first groove 3 and a second groove 4 adjacent to the first groove 3 are provided on the surface of the spiral rib 2 for contacting the liquid, wherein a rib for spacing the grooves is provided between the first groove 3 and the second groove 4. It is further explained that the first groove 3 and the second groove 4 are grooves sunken into the spiral rib 2. Therefore, the purpose of providing the first groove 3 and the second groove 4 is to expand the surface area of ​​the spiral rib 2 for contacting the fluid, thereby expanding the upper limit of the spiral rib 2 for treating the fluid.

[0030] Please continue reading Figure 2 The arrow points to the enlarged view, in which the spiral rib 2 also has an extension, and the junction with the spiral rib 2 has a rounded corner that is upward toward the extension. In this way, combined with the upward rounded corner, the upper limit of the spiral rib 2 to process fluid is further expanded, limiting the fluid from crossing the spiral rib 2.

[0031] by Figure 2 For reference, combined with Figure 3 and Figure 4In this embodiment, in order to test whether the two spiral ribs 2 provided in the two tubes 1 are accurately docked at one point, a channel 5 is provided in the extension portion. Thus, after the two tubes 1 are docked, a colored liquid is poured into the channel 5 to determine whether the spiral ribs 2 in the tube 1 and the adjacent tube 1 are successfully docked.

[0032] ① When the colored liquid flows out only from the channel 5, the spiral ribs 2 in the two tubes 1 on the surface are perfectly butted (there is no obvious difference between the amount of liquid injected and the amount of liquid discharged);

[0033] ② When the colored liquid does not flow out from the channel 5 or through the tube 1, the spiral ribs 2 of any tube 1 on the surface are exactly misaligned with the spiral ribs 2 in the other tube 1.

[0034] ③ When the colored liquid completely flows out of tube 1, the spiral ribs 2 of any tube 1 on the surface are completely offset from the spiral ribs 2 in another tube 1.

[0035] Combining ①②③ facilitates the precise connection between tubes 1.
