Technical Field
[0001] The utility model relates to the technical field of anti-corrosion elbows, in particular to a heat-insulating anti-corrosion elbow which is easy to adjust. Background Art
[0002] In modern industry and construction, piping systems are key components for transporting fluids such as water, steam, chemicals, etc. Elbows, as important components in piping systems, are used to change the flow direction and angle of pipes to accommodate different layouts and space constraints. Traditional elbows are usually prefabricated with fixed angles, which limits their application flexibility in complex or changing environments.
[0003] Disadvantages of existing elbows
[0004] Fixed angle limits flexibility: Traditional elbows are usually prefabricated with fixed angles, which limits their application flexibility in complex or changing environments. During the actual installation process, it may be necessary to adjust the angle of the elbow according to the specific conditions on site, and fixed-angle elbows cannot meet this demand.
[0005] Difficult to install and adjust: Since the angle of traditional elbows is fixed, if the angle is found to be inappropriate during installation, it may be necessary to re-customize or replace the elbow, which not only increases costs but may also cause construction delays.
[0006] Durability and stability issues: In high pressure or complex environments, traditional elbows may lack sufficient structural stability and mechanical strength, and are prone to deformation or damage, affecting the normal operation of the pipeline system.
[0007] Therefore, this invention proposes a heat-insulating and corrosion-resistant elbow which is easy to adjust to solve the above problems. Utility Model Content
[0008] In order to overcome the defects of the prior art, the purpose of the utility model is to provide a heat-insulating and corrosion-resistant elbow which is easy to adjust.
[0009] To achieve the above-mentioned purpose, the technical solution of the utility model is implemented as follows: an insulated and anti-corrosion elbow that is easy to adjust, comprising an adjustable elbow body, the innermost side of the adjustable elbow body is arranged as an inner tube body, the outer side of the inner tube body is arranged with an insulation layer, the outer side of the insulation layer is arranged with a shaping layer, the outer side of the shaping layer is arranged with an outer protective layer, the interior of the shaping layer is arranged with a grouting cavity, and the interior of the grouting cavity is filled with plastic material.
[0010] Preferably, the inner tube body is made of a bendable corrugated tube material.
[0011] Preferably, the thermal insulation layer is filled with thermal insulation cotton material.
[0012] Preferably, polyurethane slurry is injected into the grouting cavity, and the shaping layer is made of fluororubber.
[0013] Preferably, the outer protective layer is made of polyethylene.
[0014] Preferably, an inner anti-corrosion layer is provided on the inner side of the inner tube body.
[0015] Preferably, the inner anti-corrosion layer is formed by spraying anti-corrosion paint.
[0016] Preferably, butt joints are provided at both ends of the adjustable elbow body.
[0017] Preferably, a grouting valve pipe and a grouting valve pipe are respectively provided on the lower pipe wall and the upper pipe wall of the adjustable elbow body, and the grouting valve pipe and the grouting valve pipe both lead to the interior of the grouting cavity.
[0018] The beneficial effects of the utility model are embodied in:
[0019] Flexible bending angle adjustment: The design of the adjustable elbow body allows for flexible adjustment of the bending angle in the initial stage. The inner tube body is made of bendable corrugated tube material, which enables the elbow to adapt to various angle adjustment requirements. This design is particularly suitable for scenarios where the pipeline direction needs to be adjusted according to actual conditions at the installation site, which improves the flexibility and adaptability of the pipeline system.
[0020] Post-setting ensures stability: The grouting cavity inside the setting layer is filled with polyurethane slurry, which is injected after the bending angle is adjusted, and the setting is completed after the slurry solidifies. This post-setting design ensures the structural stability and mechanical strength of the elbow under high-pressure environment, and enhances the impact resistance and durability of the elbow.

This design not only extends the service life of the elbow, but also ensures the purity of the medium and the safety of the pipeline system, while improving the energy efficiency and the weather resistance and corrosion resistance of the overall structure.
[0022] In summary, this easily adjustable thermal insulation and anti-corrosion elbow significantly improves the flexibility, stability and durability of the pipeline system through its unique multi-layer structure design and flexible bending angle adjustment function. Its design not only takes into account the selection of materials and the optimization of structure, but also takes into account the convenience of installation and the overall performance of the system. Through this innovative design, the adjustable elbow body not only meets the needs of modern industry for efficient and reliable pipeline systems, but also provides more flexibility and options for engineering design and construction.

[0031] The utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. 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.
[0032] It should be noted that if the utility model embodiments involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0033] In addition, "multiple" means more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.
[0034] Please refer to the instruction manual Figure 1-Figure 4The utility model provides an adjustable thermal insulation and anti-corrosion elbow, including an adjustable elbow body 1, characterized in that the innermost side of the adjustable elbow body 1 is set as an inner tube body 11, the outer side of the inner tube body 11 is provided with a thermal insulation layer 12, the outer side of the thermal insulation layer 12 is provided with a shaping layer 13, the outer side of the shaping layer 13 is provided with an outer protective layer 14, the inner side of the shaping layer 13 is provided with a grouting cavity 131, and the inner side of the grouting cavity 131 is filled with a plastic material.
[0035] Adjustable elbow body 1: includes an inner tube body 11 arranged at the innermost side, which is made of a bendable corrugated tube. This corrugated tube not only has good flexibility and can adapt to the adjustment requirements of various angles, but also has high strength and can withstand the pressure of the medium inside the pipeline. The inner side of the inner tube body is sprayed with anti-corrosion paint to form an inner anti-corrosion layer 15. This anti-corrosion paint has excellent acid and alkali resistance and corrosion resistance, effectively prolongs the service life of the inner tube body, and ensures the purity of the medium and the safety of the pipeline system.
[0036] The outer side of the inner pipe body 11 is wrapped with an insulation layer 12, which is filled with high-efficiency insulation cotton material with low thermal conductivity and good high temperature resistance. This can not only maintain a good insulation effect in various working environments and reduce heat loss, but also prevent the formation of condensed water and protect the external structure of the pipeline from moisture erosion, thereby improving the energy efficiency of the entire pipeline system.
[0037] A shaping layer 13 is arranged outside the thermal insulation layer 12. The shaping layer is made of fluororubber material and can adjust the angle between grouting in the grouting cavity 131. Grouting can be performed after the bending angle adjustment operation is completed. Then, the shaping is completed after the slurry solidifies. The bending angle of the entire elbow can be customized according to the actual situation. A grouting cavity 131 is arranged inside the shaping layer. The grouting cavity is filled with polyurethane slurry. This material forms a tough solid after solidification, which can further enhance the structural stability of the shaping layer and provide additional mechanical strength and impact resistance, ensuring the safety and reliability of the elbow under high pressure environment.
[0038] A grouting valve pipe 3 and a grouting valve pipe 4 are respectively arranged on the lower and upper pipe walls of the adjustable elbow body 1. The grouting valve pipe 3 and the grouting valve pipe 4 are both connected to the interior of the grouting cavity 131. During the grouting operation, the grouting is injected from the grouting valve pipe 3 until the slurry is discharged from the grouting valve pipe 4, and the entire grouting cavity 131 is filled. Then the grouting valve pipe 3 and the grouting valve pipe 4 can be blocked, and the slurry is waited for to solidify, thereby completing the customized operation of the angle elbow.
[0039] The shaping layer 13 is coated with an outer protective layer 14, which is made of polyethylene material and has good weather resistance, corrosion resistance and aging resistance. The use of polyethylene material enables the outer protective layer to effectively resist various chemicals, ultraviolet rays and mechanical damage in the external environment, and maintain the overall structural integrity and appearance quality of the elbow.
[0040] The outer protective layer 14 is the outermost layer of the overall structure. It not only protects the inner layer material from damage by external physical and chemical factors, but also provides a certain flexibility to adapt to the slight deformation of the pipeline during installation and use, and prevent structural damage caused by excessive rigidity.
[0041] Both ends of the adjustable elbow body are provided with butt joints 2, which adopt a standard interface design and can be quickly and conveniently connected to other pipeline systems. This not only improves the convenience of installation, but also ensures the compatibility and sealing of the system, avoiding leakage problems caused by poor connection. In addition, the design of the butt joint also takes into account the operability of on-site construction, reducing installation time and labor costs.
[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
[0043] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
