Description

Technical Field

[0001] The utility model belongs to the technical field of waste pipes, and in particular relates to a recyclable waste pipe. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles. Usually, the fluid is pressurized by blowers, compressors, pumps and boilers, and then flows from the high-pressure part of the pipeline to the low-pressure part. It can also be conveyed by the fluid's own pressure or gravity. Pipelines are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations. When a pipeline becomes scrapped during use, it needs to be dismantled and replaced to ensure the normal operation of the entire pipeline system.

[0003] When existing pipes are damaged and scrapped during use, they are removed from the entire pipeline system and replaced with new pipes. The removed scrapped pipes become waste pipes, but there are the following defects: (1) The existing pipes that are removed from the pipeline system and become waste pipes can only be scrapped and their partial structures cannot be recycled and reused, resulting in a low recycling rate of waste pipes. For this reason, we propose a recyclable waste pipe. Utility Model Content

[0004] The utility model aims to provide a recyclable waste pipe to solve the problem that the waste pipe structure proposed in the above background technology cannot be recycled and reused, resulting in low utilization rate.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a recyclable waste pipe, comprising an outer sleeve and two inner tubes, a threaded connection ring is fixed at the inner center of the outer sleeve, the inner tube is inserted into the inner part of the outer sleeve, and the two inner tubes are symmetrical about the threaded connection ring, and one end of the inner tube is connected to the threaded connection ring by a thread.

[0006] Preferably, the longitudinal section of the inner tube is a circular structure, and the cross section of the inner tube is a T-shaped structure.

[0007] Preferably, one end surface of the inner tube is provided with a conical surface.

[0008] Preferably, the longitudinal section of the threaded connection ring is a circular structure, and the threaded connection ring and the inner wall of the outer sleeve are connected by welding.

[0009] Preferably, a sealing gasket is provided between the other end of the inner tube and the outer sleeve, and the sealing gasket is sleeved on the outer wall of the inner tube.

[0010] Preferably, a ball groove is formed on the inner wall of the outer sleeve, and supporting beads are embedded in the ball groove.

[0011] Preferably, the support beads are arranged in four rows, and the four rows of support beads form a circular array about the central axis of the outer sleeve.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) Through the designed outer sleeve, two inner tubes and threaded connection ring, the two inner tubes are symmetrically inserted into the outer sleeve, and the ends are screwed and tightened to connect with the threaded connection ring. The two inner tubes are assembled into the outer sleeve. When the pipeline is scrapped, if the inner tube is not damaged, it can be disassembled and recycled to improve the utilization rate of the scrapped pipe. The designed conical surface is set at the end of the inner tube to ensure that the inner tube is inserted into the outer sleeve more smoothly and prevent one end of the inner tube from being blocked during the insertion process. The designed sealing gasket is set between the end of the inner tube and the outer sleeve to seal the connection between the two ends. The designed four rows of support beads support the inner tube in the outer sleeve to ensure that the inner tube is straight in the outer sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example

[0022] See also Figures 1 to 5 The utility model provides a technical solution: a recyclable waste pipe, comprising an outer sleeve 1 and two inner pipes 3, a threaded connection ring 4 is fixed at the inner center of the outer sleeve 1, the inner pipe 3 is inserted into the inner part of the outer sleeve 1, and the two inner pipes 3 are symmetrical about the threaded connection ring 4. Through the designed outer sleeve 1, the two inner pipes 3 and the threaded connection ring 4, the two inner pipes 3 are symmetrically inserted into the outer sleeve 1, and the ends are screwed and tightened with the threaded connection ring 4, and the two inner pipes 3 are assembled into the outer sleeve 1. When the pipeline is scrapped, the inner pipe 3 is not damaged. When the inner tube 3 is broken, it can be disassembled for recycling to improve the utilization rate of the scrapped tube. One end of the inner tube 3 is connected to the threaded connecting ring 4 by threads. The longitudinal section of the inner tube 3 is a circular structure, and the cross section of the inner tube 3 is a T-shaped structure. A conical surface 5 is provided on the surface of one end of the inner tube 3. The conical surface 5 is designed and arranged at the end of the inner tube 3 to ensure that the inner tube 3 is inserted into the outer tube 1 more smoothly and prevent one end of the inner tube 3 from being blocked during the insertion process. The longitudinal section of the threaded connecting ring 4 is a circular structure, and the threaded connecting ring 4 and the inner wall of the outer tube 1 are connected by welding.

[0023] In this embodiment, preferably, a sealing gasket 6 is provided between the other end of the inner tube 3 and the outer sleeve 1. The sealing gasket 6 is designed and arranged between the end of the inner tube 3 and the outer sleeve 1 to seal the connection between the two ends, and the sealing gasket 6 is sleeved on the outer wall of the inner tube 3. The inner wall of the outer sleeve 1 is provided with a ball groove, and the ball groove is inlaid with support beads 2. The inner tube 3 in the outer sleeve 1 is supported and held by the designed four rows of support beads 2 to ensure that the inner tube 3 is straight in the outer sleeve 1. The support beads 2 are four rows, and the four rows of support beads 2 form a circular array about the central axis of the outer sleeve 1.

[0024] The working principle and use process of the utility model are as follows: the utility model sleeves the sealing gasket 6 on the outer wall of one end of the inner tube 3, and then symmetrically inserts the two inner tubes 3 into the outer tube 1. During the insertion process, the end of the inner tube 3 is a conical surface 5 structure with a certain slope, thereby playing an avoidance role, preventing the end edge of the inner tube 3 from being a right-angled side and easily blocking the internal structure of the outer tube 1, affecting the smooth insertion of the inner tube 3 into the inner part of the outer tube 1, and the end and the threaded connecting ring 4 are screwed and tightened to connect the two inner tubes 3 into the outer tube 1. When the pipeline is scrapped and its inner tube 3 is not damaged, the inner tube 3 is rotated, and the external thread at the end of the inner tube 3 and the internal thread of the threaded connecting ring 4 are screwed and changed in position, and the end of the inner tube 3 is screwed and separated from the threaded connecting ring 4, and then the inner tube 3 is pulled out from the inside of the outer tube 1, so that the inner tube 3 can be disassembled for recycling and reuse, thereby improving the utilization rate of the scrapped pipe.
