Description

Technical Field

[0001] The utility model belongs to the technical field of pipe production, in particular to a PE pipe sizing sleeve for greening and irrigation water delivery. Background Art

[0002] PE pipes have good hygienic properties, are non-toxic, and have no scaling layer. When transporting water in pipes, secondary pollution of water quality can be avoided. Standard PE pipes have high impact resistance, good toughness, and high impact resistance, which will not cause the pipe to rupture.

[0003] In the existing PE pipe production process, the PE pipe blank extruded by the extruder must be cooled and solidified before it can be truly formed into a pipe. The cooling and shaping of the pipe is first passed through the sizing sleeve of the extruder, and the first cooling is carried out through the water sealing ring that cooperates with the sizing sleeve, and then enters the cooling pool behind the sizing sleeve or the cooling system to achieve complete cooling and shaping. When the sizing sleeve and the water sealing ring are cooled for the first time, water is discharged through the water sealing ring, so that a layer of water film is formed between the outer surface of the PE pipe and the sizing sleeve. The water film has the function of cooling the pipe. At the same time, the water film can lubricate the sizing sleeve and the pipe, reduce the friction between the sizing sleeve and the PE pipe, and make the outer surface of the PE pipe smoother.

[0004] For example, the utility model patent with patent number CN201320317393.X discloses a PE pipe sizing sleeve, including a mounting plate, a through hole is provided in the center of the mounting plate, a number of mounting holes are evenly distributed around the through hole, a sizing sleeve is fixedly installed in the through hole, a shaping sleeve is installed inside the sizing sleeve, a conduit is led out from the rear end of the shaping sleeve, a number of waist-shaped holes are evenly opened on the conduit wall, a screw hole is opened on the wall of the sizing sleeve and a gas outlet nose is screwed in, an end cap is provided at the mouth of the sizing sleeve, a conical hole is provided on the end cap and points to the center of the shaping sleeve, and the sizing sleeve, shaping sleeve and end cap are all made of copper. The utility model has a reasonable and simple structural design, is convenient and quick to assemble and disassemble, can accurately control the diameter of the PE pipe, is not easy to be broken, and improves its service life.

[0005] The wall of some PE pipes used for greening and irrigation water supply is thin. During the pipe drawing process, it needs to be quickly shaped and cooled, otherwise the protective pipe is easy to deform. However, during the sizing process of the PE pipe in the sizing sleeve, the protective pipe is not cooled in time and the surface of the protective pipe is not lubricated with water, which will cause the protective pipe to deform.

However, during the sizing process of the PE pipe in the sizing sleeve, the protective pipe is not cooled in time and the surface of the protective pipe is not lubricated with water, which will cause the protective pipe to deform.

[0025] Please see Figures 1 to 6The PE pipe sizing sleeve for greening and irrigation water delivery comprises a sizing pipe 100 and a cooling pipe 200 and a connecting portion 300 located at both ends of the sizing pipe 100. The surface of the sizing pipe 100 is evenly distributed with water injection grooves 110, and the water injection grooves 110 penetrate the pipe wall of the sizing pipe 100. The surface of the cooling pipe 200 is evenly distributed with water injection holes 210, and the water injection holes 210 penetrate the pipe wall of the cooling pipe 200. The first end of the water injection hole 210 is provided with a first expansion portion 211, and the first expansion portion 211 is located on one side of the outer wall of the water injection hole 210, and the first expansion portion 211 is funnel-shaped. The sizing sleeve is fixed and fixed with a matching device through the connecting part 300. The connecting part 300 is a flange. The sizing pipe 100 and the cooling pipe 200 are integrally manufactured. After the PE pipe for greening and irrigation water is extruded from the extruder, it first enters the sizing pipe 100 for sizing. The surface of the sizing pipe 100 is evenly distributed with water injection grooves 110. Cooling water is sprayed on the outer surface of the sizing pipe 100. The cooling water will enter the sizing pipe 100 along the water injection grooves 110, forming a layer of water film on the outer surface of the protective pipe in the sizing pipe 100, which has a preliminary cooling effect and a water lubrication effect, preventing the relatively soft PE pipe for greening and irrigation water from sizing. The E-tube sticks to the sizing tube 100, but the sizing tube 100 mainly plays a sizing role and has a poor cooling effect. Therefore, after the protective tube enters the cooling tube 200, it is necessary to enhance the cooling effect of the protective tube, and spray cooling water on the outer surface of the cooling tube 200. Since the first end of the water injection hole 210 is provided with a first funnel-shaped expansion portion 211, the sprayed cooling water can more easily enter the cooling hole along the first funnel-shaped expansion portion 211, and fit with the outer wall of the PE pipe for greening and irrigation water supply in the cooling tube 200, thereby improving the cooling effect and water lubrication effect of the cooling tube 200, and avoiding the deformation and adhesion of the PE pipe for greening and irrigation water supply to the inner wall of the sizing sleeve.

[0026] For further description, see Figure 6 The second end of the water injection hole 210 is provided with a second expansion portion 212, which is located on one side of the inner wall of the water injection hole 210 and is funnel-shaped. After the cooling water flowing in from the water injection hole 210 enters the second expansion portion 212, the cooling water will be diverted, so that more cooling water will contact the protection tube, increasing the contact area between the cooling water and the protection tube, and further improving the cooling effect and water lubrication effect of the cooling tube 200.

[0027] For further information, see Figures 4 to 6A plurality of drainage grooves 213 are evenly arranged in the water injection hole 210, and the drainage grooves 213 extend along the first expansion portion 211 to the second expansion portion 212. The drainage grooves 213 can increase the water injection volume of the water injection hole 210, so that more cooling water enters the water injection hole 210. At the same time, the drainage grooves 213 have a drainage effect, so that the cooling water can quickly flow into the second expansion portion 212.

[0028] Specifically, the drainage grooves 213 are provided in two groups.

[0029] Specifically, the drainage grooves 213 are provided in four groups.

[0030] Specifically, the drainage grooves 213 are provided in 8 groups.

[0031] Furthermore, the cross section of the drainage groove 213 is one of an arc shape, a right angle shape, and a V shape, so as to facilitate the drainage of cooling water.

[0032] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
