Technical Field

[0001] This utility model relates to the field of cast stone composite pipe technology, and in particular to a high-strength cement-bonded cast stone composite pipe. Background Technology

[0002] High-strength cement-bonded cast stone composite pipe is a type of pipe used for conveying highly abrasive and corrosive media.

It combines the advantages of impact and abrasion resistance with chemical corrosion resistance. Currently, high-strength cement-bonded cast stone composite pipes are typically installed by aligning two composite pipes together using a crane or mechanical gripper, and then connecting them via flanges. However, this method requires high precision in aligning the two composite pipes for flange connection, resulting in extremely high skill requirements for the operators and slow installation speed. Therefore, improvements are needed to address the aforementioned issues. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-6This utility model discloses a high-strength cement-bonded cast stone composite pipe, comprising a protective layer 1, which is a circular tube structure with one end expanding outward and the other end contracting inward. A support frame 8 is installed inside the protective layer 1, which is composed of circular and cylindrical steel bars. The support frame 8 facilitates the support of the protective layer 1. Connecting components are installed at both ends of the protective layer 1, and sealing components are installed inside the connecting components. An expansion layer 3 is installed inside the protective layer 1, with its outer wall adhering to the inner wall of the protective layer 1. An inner lining layer 4 is installed inside the expansion layer 3, with its outer wall adhering to the inner wall of the expansion layer 3. The expansion layer 3 facilitates the prevention of separation between the protective layer 1 and the inner lining layer 4.

[0020] In this utility model, the connecting assembly includes flanges 2 installed at both ends of the protective layer 1. One flange 2 is connected to the other flange 2 of the other protective layer 1 by bolts 7. A sealing ring is installed at one end of the protective layer 1, and a sealing groove that mates with the sealing ring is opened at the other end of the protective layer 1. The flanges 2 facilitate quick fixation of the two composite pipes. The sealing assembly includes a feed pipe installed on the outside of one end of the protective layer 1. The feed pipe passes through the protective layer 1, the expansion layer 3, and the inner lining layer 4. A nut 5 is threaded onto the feed pipe. A connecting groove is opened at one end of the inner wall of the protective layer 1 in the inner lining layer 4. The connecting groove is filled with sealant 6. The sealant 6 is injected through the feed pipe. The connecting groove and the sealant 6 facilitate sealing of the connection between the composite pipes.

[0021] Working principle: When using this utility model, first align one end of a composite pipe with the connector of another composite pipe, and insert the composite pipe into the connecting groove inside the connector. At this time, connect the two flanges 2 with bolts 7. After the flanges 2 are connected, sealant 6 can be injected into the interlayer between the connector and the composite pipe through the feed pipe. When the sealant 6 solidifies, it can seal the connection. When the external temperature is extreme, causing the protective layer 1 and the inner lining layer 4 to expand or contract, the expansion layer 3 connects the two layers, which can fill the internal gap and prevent the composite pipe from being damaged. At the same time, the support skeleton 8 inside the protective layer 1 can support the composite pipe, thereby protecting the composite pipe.

[0022] 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. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
