Problems solved by technology

[0005] (1) Usually, the scope of the oxide layer scraped off by the scraper is half of the length of the welded pipe fittings, and the fixed ring of the device is fixed on the outer wall of the pipe, which can only scrape off a local area. When in use, the position of the fixed ring needs to be adjusted so that It scrapes off the part away from the nozzle, which is not easy to operate;
[0006] (2) The size of the fixing ring of this structure is fixe

Example Embodiment

[0060] Example 1

[0061] The PE pipe scraper device of the present invention, such as figure 1 As shown, it includes a first tubular structure 1 and a second tubular structure 2 that both have elasticity, the inner wall of the first tubular structure 1 is sleeved on the outer wall of the PE pipe 5, and the outer wall of the second tubular structure 2 is supported with the inner wall of the PE pipe 5. touch;

[0062] A scraper 4 is arranged on the pipe wall of the first tubular structure 1, and the blade of the scraper 4 is in contact with the outer wall of the PE pipe. Under the action of external force, the first tubular structure 1 drives the scraper 4 on the outer wall of the PE pipe 5 along the PE pipe. 5. Circumferential movement, scraper 4 scrapes the material on the outer wall of the PE pipe during the circumferential movement;

[0063] The shape and size of the second tubular structure 2 matches the shape and size of the inner wall of the PE pipe 5. The pipe wall of...

Example Embodiment

[0066] Example 2

[0067] On the basis of Example 1, the second tubular structure is fixed on the inner wall of the PE pipe 5. When placed, the cross-sectional area of ​​the second tubular structure is reduced by external force. The insertion end of the side is inserted into the opening, and as the size of the second tubular structure is further reduced, the insertion end is further moved into the cavity inside the second tubular structure, and after it is reduced to be smaller than the inner diameter of the PE pipe, the second tubular structure is Put it into the PE tube, so that the side of the second tubular structure is in contact with the inner wall of the PE tube. After being put in, the second tubular structure will automatically adapt to the size of the inner diameter of the PE tube until the inner wall of the PE tube acts on the second tubular structure. The size of the second tubular structure is fixed, and the second tubular structure is further supported. At this t...

Example Embodiment

[0070] Example 3

[0071] On the basis of Example 2, the structure of the second tubular structure is as follows image 3 and 4 shown, image 3 It is the structure of the second tubular structure when there is no external force. When the insertion end of the second tubular structure is inserted into the open end, its structure is as follows: Figure 4 shown. like Figure 9 and 10 As shown, a telescopic rod 21 is connected to the inner wall of the second tubular structure 2. The telescopic rod 21 is located on the plane where the cross section of the second tubular structure 2 is located. The length of the telescopic rod 21 is adjusted according to the shape and size of the second tubular structure 2. The rod 21 includes an accommodating cavity 201 with one end open, and an adjusting rod 202. The adjusting rod 202 is sheathed in the accommodating cavity 201, one end of the adjusting rod 202 is connected to the inner bottom of the accommodating cavity 201 through a spring 2...

Abstract

The invention discloses a PE tube scraper device and a method for scraping a material on an outer wall of a PE tube. An inner wall of a first tubular structure is sleeved on the outer wall of the PE tube, and an outer wall of a second tubular structure is in support contact with the inner wall of the PE tube; at least one scraper is arranged on the tube wall of the first tubular structure, the first tubular structure drives the scraper to move on the outer wall of the PE tube in a circumferential direction of the PE tube, and the scraper scrapes off the material on the outer wall of the PE tube during the circumferential movement; and the shape and size of the second tubular structure are matched with the shape and size of the inner wall of the PE tube. This structure is applicable to different PE tubes with different sizes; and at the same time, during use, the condition that the scraped part of the PE tube is deformed due to uneven force and then affects the quality of electrofusionwelding does not occur.

Description

technical field [0001] The invention relates to the field of PE pipes, in particular to a PE pipe scraper device and a method for scraping the outer wall of PE pipes. Background technique [0002] The pipe fittings of polyethylene piping system are mainly divided into two types: hot melt pipe fittings and electrofusion pipe fittings. During construction, electrofusion pipe fittings are less affected by the external environment and human factors, so they have better reliability and are more popular with users. Especially in gas pipe engineering, electrofusion fittings are being used more and more. At the same time, due to the complex production technology, high cost and high sales price of electrofusion pipe fittings, the profit margin of electrofusion pipe fittings manufacturers is also higher, and it has become a hot spot for investment. [0003] Before the PE pipe is fused, the surface oxide layer and contaminants of the part to be welded need to be cleaned up. In actual ...
