[0001] This utility model relates to the field of 90-degree elbow technology, specifically to an impact-resistant and wear-resistant 90-degree long-radius elbow. Background Technology

[0002] A 90-degree elbow is a pipe fitting used to change the direction of a pipeline. Its core feature is that it causes a right-angle turn in the direction of fluid flow. It is a basic component of pressure pipeline systems and is widely used in chemical, petroleum, power, water treatment and other fields. A 90-degree elbow is not a simple geometric component, but a comprehensive engineering solution involving fluid mechanics, materials science and mechanical strength.

[0003] In the prior art, 90-degree elbows may be damaged or deformed due to the long-term impact of internal liquid during use. In order to resist deformation, we propose an impact-resistant and wear-resistant 90-degree long-radius elbow. Utility Model Content

[0016] 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.

[0017] Reference Figure 1-2An impact-resistant and wear-resistant 90-degree long-radius elbow includes a connecting pipe 1. A bend body 8 is mated to the side wall of the connecting pipe 1. The inner wall of the bend body is coated with a wear-resistant ceramic coating, which can significantly improve the service life of the pipe. A first L-bar 5 is provided on one side of the bend body 8. The L-bar is made of stainless steel and has good structural strength and fatigue resistance. A contact device is fixedly connected to the side wall of the first L-bar 5. The design of the contact device can effectively disperse the stress concentration generated during the operation of the pipe.

[0018] The contact device includes an arc-shaped plate 6 fixedly connected to the side wall of the first L-bar 5. This arc-shaped plate is precision-machined to ensure a perfect fit with the bend body. The shape of the arc-shaped plate 6 corresponds to the shape of the bend in the bend body 8; this corresponding design achieves optimal support and stress distribution. The arc-shaped plate 6 abuts against the side wall of the bend body 8.

[0019] The first L-shaped rod 5 has a sliding device at one end, which allows for some displacement during thermal expansion and contraction of the pipe. A connecting seat 3, also sliding at the other end of the first L-shaped rod 5, is manufactured using a one-piece casting process to ensure structural stability. A through-hole groove is provided at the upper end of the connecting seat 3, and the inner wall of the groove is precision-machined to ensure accurate fit with the L-shaped rod. The lower end of the first L-shaped rod 5 is fitted into the groove, with the assembly gap controlled within 0.5mm to ensure operational stability.

[0020] A measuring device is fixedly connected to the side wall of the bend body 8 at the corresponding position. This measuring device can monitor the pipe displacement and stress changes in real time. The measuring device includes a scale 2 fixedly connected to the side wall of the connecting pipe 1. The scale is made using laser etching technology, and the reading accuracy reaches 0.1mm. A slot 11 is provided through the side wall of the connecting seat 3 at the corresponding position. The slot is designed with a guide slope to facilitate the centering operation during installation. The connecting pipe 1 is slidably disposed in the slot 11. The sliding surface is coated with a special lubricating coating to reduce movement resistance. The movement of the connecting seat 3 in this device is only affected by the deformation of the bend body 8. Other influencing factors are considered as existing technology and will not be described in detail in this paper.

[0021] Specifically, an auxiliary device is fixedly connected to the side wall of the bend body 8 at the corresponding position. This auxiliary device enhances the structural rigidity of the entire system. The auxiliary device includes a fixing bracket 7 fixedly connected to the side wall of the bend body 8. The fixing bracket adopts a three-point support design to ensure better force balance. A second L-rod 9 is fixedly connected to the side wall of the fixing bracket 7. The length of the second L-rod is adjustable to suit pipe systems of different sizes. The other end of the second L-rod 9 is fixedly connected to a fixing seat 10. The bottom of the fixing seat has anti-slip texture to improve installation stability.

[0022] This improved design significantly enhances the elbow's impact resistance and service life, making it particularly suitable for high-pressure, high-flow industrial pipeline systems.

[0023] In this utility model, after the operator connects the bending pipe body 8, a fixing frame 7 and a fixing seat 10 can be installed on the side wall of the bending pipe body 8 for positioning and installation. At the same time, the arc plate 6 on the other side abuts against the side wall of the bending pipe body 8. When the side wall of the bending pipe body 8 deforms, the degree of deformation can be quantified by the arc plate 6 and the connecting seat 3, and reflected by the corresponding reading on the scale 2, which is convenient for the operator to conduct regular inspections.

[0024] 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.
