Description

Technical Field

[0001] This utility model relates to the field of pipeline compensator technology, and in particular to an easily replaceable non-metallic compensator. Background Technology

[0002] Pipeline compensators, also known as expansion joints or expansion couplings, are mainly used to compensate for the thermal expansion and contraction of pipelines caused by temperature changes. If a pipeline cannot expand or contract freely during temperature changes, thermal stress will be generated within the pipeline. Pipeline compensators are divided into two types: metallic and non-metallic. Metallic compensators are commonly used to connect metallic pipelines, while non-metallic compensators are commonly used to connect non-metallic pipelines.

[0003] Non-metallic compensators mainly consist of bellows and flanges. The bellows functions as an expansion joint, while the flanges are used for connection and fixation to external pipelines. After prolonged use, the bellows of non-metallic compensators are prone to aging and damage, requiring replacement. However, in existing non-metallic compensators, the bellows and flanges are integrally molded, making separate disassembly and replacement impossible. This necessitates replacing both the bellows and flanges together, resulting in resource waste. Therefore, there is an urgent need to develop an easily replaceable non-metallic compensator that is convenient to disassemble and replace, saving resources, to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide an easily replaceable non-metallic compensator to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An easily replaceable non-metallic compensator includes a bellows, a flange, a sealing sleeve, and a clamping mechanism. Both ends of the bellows are provided with external threads. A flange is detachably connected to both ends of the bellows. A sealing sleeve is fixed to the rear side of the flange, and the sealing sleeve is fitted over the outside of the bellows. A clamping mechanism is detachably installed on the outside of the sealing sleeve, clamping the sealing sleeve to the outside of the bellows. The flange is provided with an internal thread that mates with the external threads. The clamping mechanism includes a clamp, semi-circular studs, and a fastening bolt. The upper end of the clamp is open, and two semi-circular studs are fixed to the upper end of the clamp. The two semi-circular studs are detachably fixed together by the fastening bolt.

[0007] Preferably, multiple levers are fixed to the outside of the fastening bolt.

[0008] Preferably, the corrugated pipe and flange are both made of polyethylene plastic.

[0009] Preferably, a positioning retaining ring is fixed inside the flange.

[0010] The beneficial effects of this utility model are as follows: In normal use, the end of the bellows is screwed into the flange and pressed against the retaining ring. The flange is then fixed to the external pipeline by bolts, and the clamp is tightened to the outside of the sealing sleeve, resulting in better sealing. For disassembly, first separate the flange from the external pipeline, thus separating the bellows, flange, and external pipeline. Then, manually turn the lever to rotate the fastening bolt, causing it to unscrew from the semi-circular stud. Next, pry open the opening of the clamp and remove it from the sealing sleeve. Finally, unscrew the flange from the bellows to replace it with a new one. In summary, this utility model is convenient for disassembly and replacement, saving resources. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Specific implementation examples are given below.

[0021] See Figures 1-6 In this embodiment of the utility model, an easily replaceable non-metallic compensator includes a bellows 1, a flange 2, a sealing sleeve 3, and a clamping mechanism 4. Both the bellows 1 and the flange 2 are made of polyethylene plastic, making them lightweight and possessing good corrosion resistance. External threads 101 are provided at both ends of the bellows 1. A flange 2 can be detachably connected to both ends of the bellows 1. The flange 2 is used to connect to external pipelines. A sealing sleeve 3 is fixed to the rear side of the flange 2. A sealing sleeve 3 is fitted onto the outside of the bellows 1. A clamping mechanism 4 is detachably installed on the outside of the sealing sleeve 3. The clamping mechanism 4 clamps the sealing sleeve 3 onto the outside of the bellows 1, thereby improving the sealing performance and preventing leakage. The flange 2 is provided with an internal thread 202 that mates with the external thread 101. A positioning retaining ring 201 is fixed inside the flange 2. During normal use, the end of the bellows 1 is screwed into the flange 2 and pressed against the positioning retaining ring 201. The flange 2 is then fixed to the external pipeline by bolts.

[0022] The clamping mechanism 4 includes: a clamp 401, a semi-circular stud 402, and a fastening bolt 403. The upper end of the clamp 401 is open, and two semi-circular studs 402 are fixed to the upper end of the clamp 401. The two semi-circular studs 402 are detachably fixed to each other by the fastening bolt 403. Multiple actuating rods 4031 are fixed to the outside of the fastening bolt 403. By turning the actuating rods 4031 by hand, the fastening bolt 403 is rotated, so that the fastening bolt 403 is unscrewed from the semi-circular studs 402, and the clamp 401 can be removed from the outside of the sealing sleeve 3.

[0023] Working principle: In normal use, the end of the bellows 1 is screwed into the flange 2 and pressed against the retaining ring 201. The flange 2 is fixed to the external pipeline by bolts, and the clamp 401 is tightened to the outside of the sealing sleeve 3 for better sealing. When disassembling, first separate the flange 2 from the external pipeline, thereby separating the bellows 1 and flange 2 from the external pipeline. Then, turn the lever 4031 by hand to rotate the fastening bolt 403, so that the fastening bolt 403 is unscrewed from the semi-circular stud 402. Then, pry open the opening of the clamp 401 and remove the clamp 401 from the sealing sleeve 3. Finally, unscrew the flange 2 from the bellows 1 to replace the new bellows 1.

[0024] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
