Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe technology, specifically to a basalt-reinforced BFM double-wall corrugated pipe. Background Technology

[0002] A corrugated pipe is a flexible pipe element with a regular corrugated structure on its wall, which can absorb displacement, compensate for vibration, or seal the medium through deformation.

[0003] However, the existing corrugated pipe joints have smooth surfaces, and the connection between the two corrugated pipes is achieved by simply inserting one end of one corrugated pipe into the other end. This results in poor connection stability between the two corrugated pipes. Therefore, a basalt-reinforced BFM double-wall corrugated pipe is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a basalt-reinforced BFM double-wall corrugated pipe, which has the advantage of a stable and secure connection, thus solving the problem of poor connection stability in existing corrugated pipes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a basalt-reinforced BFM double-wall corrugated pipe, comprising a first corrugated pipe and a second corrugated pipe, wherein a connecting structure is provided between the first corrugated pipe and the second corrugated pipe;

[0006] The connection structure includes a corrugated sleeve fixedly installed on the inner wall of the first corrugated pipe, and a corrugated insert fixedly installed on the surface of the second corrugated pipe.

[0007] Furthermore, the corrugated sleeve is compatible with the corrugated insertion tube.

[0008] Furthermore, a sealing rubber collar is fixedly installed on the inner surface of the corrugated sleeve, and a sealing rubber retaining ring is fixedly installed on the outer surface of the corrugated tube. An annular groove is formed on the inner surface of the sealing rubber collar.

[0009] Furthermore, the sealing rubber retaining ring is adapted to the annular retaining groove.

[0010] Furthermore, an annular skeleton is fixedly installed inside the sealing rubber retaining ring.

[0011] Furthermore, both the first and second corrugated pipes are basalt fiber pipes.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] This basalt-reinforced BFM double-wall corrugated pipe features a corrugated sleeve and a corrugated insert on the first and second corrugated pipes, respectively. During use, the corrugated insert is inserted into the inside of the corrugated sleeve, and the engagement of the corrugated sleeve and the corrugated insert secures a stable connection between the two pipes. Furthermore, the use of sealing rubber collars and sealing rubber snap rings enhances the seal between the corrugated sleeve and the corrugated insert, thus preventing leakage at the connection between the first and second corrugated pipes.

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 4 The basalt-reinforced BFM double-wall corrugated pipe in this embodiment includes a first corrugated pipe 1 and a second corrugated pipe 2, with a connecting structure between the first corrugated pipe 1 and the second corrugated pipe 2.

[0021] Both the first corrugated pipe 1 and the second corrugated pipe 2 are basalt fiber pipes. Basalt fiber pipes have higher corrosion resistance, better fatigue resistance, and a longer service life. Basalt fiber has extremely high tensile strength, approximately 14 times that of PE pipes, enabling it to withstand greater pressure and mechanical impact, making it suitable for high-pressure transportation applications. Basalt fiber pipes also exhibit excellent corrosion resistance, resisting chemical corrosion and microbial erosion, eliminating the need for additional anti-corrosion measures.

[0022] The connection structure includes a corrugated sleeve 3 fixedly installed on the inner wall of the first corrugated pipe 1, and a corrugated insert 5 fixedly installed on the surface of the second corrugated pipe 2. The corrugated sleeve 3 and the corrugated insert 5 are adapted to each other, so that the corrugated insert 5 can be inserted into the inside of the corrugated sleeve 3.

[0023] Among them, a sealing rubber collar 7 is fixedly installed on the inner surface of the corrugated sleeve 3, and a sealing rubber retaining ring 9 is fixedly installed on the outer surface of the corrugated insert 5. An annular groove 8 is opened on the inner surface of the sealing rubber collar 7. The sealing rubber retaining ring 9 is adapted to the annular groove 8, which helps to improve the sealing performance between the corrugated sleeve 3 and the corrugated insert 5.

[0024] It should be noted that an annular skeleton 10 is fixedly installed inside the sealing rubber retainer 9, which helps to enhance the structural strength of the sealing rubber retainer 9.

[0025] The working principle of the above embodiments is as follows:

[0026] During connection, the corrugated tube 5 is aligned and inserted into the corrugated sleeve 3. As the corrugated tube 5 is continuously inserted, the outer surface of the corrugated tube 5 gradually contacts and engages with the inner surface of the corrugated sleeve 3. When the corrugated tube 5 is inserted to the appropriate position, the sealing rubber retainer 9 on the outer surface of the corrugated tube 5 will gradually contact the sealing rubber retainer 7 on the inner surface of the corrugated sleeve 3. When the corrugated tube 5 is inserted to the final position, the sealing rubber retainer 9 will be tightly embedded in the annular retaining groove 8, achieving a seal between the corrugated tube 5 and the corrugated sleeve 3. At the same time, the annular skeleton 10 fixedly installed inside the sealing rubber retainer 9 can enhance the structural strength of the sealing rubber retainer 9 and prevent it from deforming under pressure.

[0027] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
