[0018] The technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0019] The novel pressure pipe of the utility model, including pipeline main body 100 and fixedly installed flange 200 on the upper and lower ends of the pipeline main body 100, the upper and lower ends of the flange 200 correspond to the water inlet 1 and the water outlet 6 respectively, the turbulence protrusion 2 and the spiral flow guide layer are sequentially fixedly arranged on the inner wall of the pipeline main body 100, and the spiral vortex plate mechanism 5 is fixedly installed on the pipeline main body 100.

[0020] Further, the pipeline body 100 is usually made of high-performance materials such as pressure-resistant, corrosion-resistant, and high-temperature-resistant materials, preferably alloy materials, to protect the internal structure from external environmental damage.

[0021] Further, the flanges 200 fixedly installed on the upper and lower ends of the pipeline body 100 are used to connect with the flanges of adjacent pipelines or equipment. The flanges 200 are provided with standard bolt holes for quick installation and disassembly. The inner cavity of the pipeline body 100 constitutes a water flow channel, and the flanges 200 fixedly installed on the upper and lower ends of the pipeline body 100 are the water inlet 1 and the water outlet 6, respectively.

[0022] Further, the turbulence protrusions 2 fixedly arranged on the inner wall of the pipeline body 100 are located at the front end of the pipeline wall of the pipeline body 100. The turbulence protrusions 2 are staggered hemispherical protrusions, which are used to break the laminar boundary layer and prevent particle deposition. The hemispherical turbulence protrusions are made by laser sintering process. The specific working principle of the turbulence protrusions 2 arranged at the front end of the pipeline wall of the pipeline body 100 is as follows: during fluid flow, the formation of the laminar boundary layer will increase the frictional resistance between the fluid and the inner wall of the pipeline, while reducing the heat and mass transfer efficiency. The design of the turbulence protrusions 2 can effectively break this boundary layer, making the fluid produce turbulent flow during the flow process, thereby increasing the contact area and mixing degree between the fluid and the inner wall of the pipeline. Meanwhile, in the fluid, especially in the fluid containing solid particles, particles are prone to deposit on the inner wall of the pipeline, causing pipeline blockage or wear. The hemispherical design of the turbulence protrusions 2 can change the flow direction of the fluid, so that the particles are subjected to greater impact force during the flow process, thereby being difficult to deposit on the inner wall of the pipeline.

[0023] Further, the spiral flow guide layer located behind the turbulence protrusions 2 is a variable-pitch spiral groove. Specifically, the spiral flow guide layer includes a front-pitch spiral groove 3 and a rear-pitch spiral groove 4. The front-pitch spiral groove 3 is 50-80mm, and the rear-pitch spiral groove 4 is 100-150mm. The groove depth is 20%-30% of the thickness of the pipeline wall. The specific working principle is as follows: when the fluid flows through the turbulence protrusions 2, its flow state is changed to form turbulent flow. Subsequently, the fluid enters the front-pitch spiral groove 3 of the spiral flow guide layer. The small-pitch spiral groove can quickly guide the fluid to flow along the spiral direction at a high speed, while increasing the contact area between the fluid and the inner wall of the pipeline and improving the heat transfer efficiency. As the fluid continues to flow, it enters the rear-pitch spiral groove 4. Since the rear-pitch is larger, the flow speed of the fluid in the spiral groove is relatively reduced, but the flow path becomes longer. The design of the spiral flow guide layer takes into account the pressure loss of the fluid in the pipeline. By adjusting the pitch and groove depth, the unnecessary pressure loss can be minimized while ensuring the fluid transmission efficiency.

[0024] Further, the pipe body 100 fixedly installs a spiral vortex plate mechanism 5, which comprises a circular ring-shaped fixing part 51 fixedly arranged on the inner wall of the pipe body 100, a support part 53 horizontally arranged at the center of the fixing part 51, and a cylinder 54 nestedly connected at the center of the support part 53. The cylinder 54 nestedly connected at the center of the support part 53 is rotatable, and turbine blades 52 are arranged around the cylinder. The rotation of the cylinder 54 drives the rotation of the turbine blades 52. The turbine blades 52 are arranged in a spiral shape. When fluid flows through, the turbine blades 52 are impacted by the fluid and rotate. The design of the spiral vortex plate mechanism 5 not only makes the fluid rotate in the pipe, but also optimizes the flow state of the fluid by changing the flow direction of the fluid. The rotation of the spiral vortex plate mechanism 5 can also produce a certain pressure adjustment effect on the fluid.

[0025] The novel pressure pipe disclosed by the utility model has the combined structure of the turbulence protrusion, the spiral flow guide layer and the spiral vortex plate mechanism, which significantly improves the turbulence degree and heat transfer efficiency of fluid in the pipe, and the combined structure of the turbulence protrusion and the spiral flow guide layer has the functions of reducing resistance and preventing deposition, so that the novel pressure pipe has wide application prospects in the transmission of high-pressure fluid, high-temperature fluid or corrosive fluid.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the utility model.
