Description

Technical Field

[0001] This utility model relates to the field of end cap docking technology, and more specifically, to a docking and fixing structure for non-metallic containers. Background Technology

[0002] The flow field experiment in the lower chamber of a reactor is a crucial step in studying the hydraulic characteristics of a reactor. To conduct this experiment, a transparent experimental container needs to be designed and manufactured based on the structure of the reactor prototype. This container typically consists of a cylindrical body made of a non-metallic transparent material and a lower end cap, which can be spherical or elliptical. Together, they form the boundary of the experimental fluid's movement.

[0003] In the design and manufacture of transparent experimental containers, we found that the poor mechanical properties of transparent non-metallic materials made the connection, sealing, and fixation between the cylindrical body and the end cap extremely difficult. Under internal pressure, non-metallic containers are prone to leakage or flange breakage. Furthermore, when using elliptical end caps, the uneven stress distribution under pressure due to the varying curvature of their inner walls can easily lead to deformation. Utility Model Content

[0004] The purpose of this invention is to provide a docking and fixing structure for non-metallic containers, which solves the problems of connection, sealing and deformation of non-metallic cylinders and end caps.

[0005] This utility model is achieved through the following technical solution: a docking and fixing structure for non-metallic containers, used for docking and fixing a cylinder and a head, including a docking ring, a first slot for engaging the cylinder on the upper inner side of the docking ring, a second slot for engaging the head on the lower inner side of the docking ring, a connecting rod for fixing the relative position of the docking ring connected to the top of the docking ring, and a base for supporting the head connected to the bottom of the docking ring.

[0006] Furthermore, the base includes a support ring and reinforcing ribs, with at least three reinforcing ribs provided, and the reinforcing ribs are centrally symmetrically distributed with the support ring as the center.

[0007] Preferably, one end of the reinforcing rib is bolted to the butt ring, and the other end of the reinforcing rib is welded to the support ring, with the inner wall of the reinforcing rib tightly fitted to the outer wall of the end cap.

[0008] Preferably, the installation positions of the connecting rods on the mating rings are vertically aligned with the positions where the reinforcing ribs are laid out.

[0009] Furthermore, the mating ring has a spacer ring between the cylinder and the end cap, and the inner wall of the spacer ring is smoothly mated with the inner walls of both the cylinder and the end cap.

[0010] Furthermore, a first sealing ring that contacts the outer wall of the cylinder is provided in the first slot, and a second sealing ring that contacts the outer wall of the end cap is provided in the second slot.

[0011] Furthermore, the docking ring, connecting rod, and base are all made of metal.

[0012] This utility model has at least the following advantages and beneficial effects: by fixing the relative position of the docking ring with the connecting rod, it provides support for the cylinder. When the end cap is inserted into the end cap and fixed by the bottom support, the cylinder and end cap can maintain structural stability before and after disassembly and assembly, effectively improving the stability of the structure, without affecting the internal flow field of the experimental model, and ensuring the successful implementation of the visualization experiment of the flow field in the lower chamber of the reactor.

[0018] Example

[0019] like Figure 1-3As shown in this embodiment, a docking and fixing structure for non-metallic containers is disclosed. The structure is simple and reliable, and easy to assemble and disassemble. It is used for docking and fixing the non-metallic cylinder 1 and the end cap 2 of the pressurized water reactor flow field visualization experimental model. Its main structure includes a docking ring 3. The upper inner side of the docking ring 3 is provided with a first slot 31 for engaging the cylinder 1, and the lower inner side of the docking ring 3 is provided with a second slot 32 for engaging the end cap 2. The top of the docking ring 3 is connected to a connecting rod 4 for fixing the relative position of the docking ring 3, and the bottom end of the docking ring 3 is connected to a base support 5 for supporting the end cap 2. Specifically, the upper end of the connecting rod 4 is connected to the fixed structure (such as a flange or test bench) on the upper part of the cylinder 1, and the lower end of the connecting rod 4 is threaded to the docking ring 3 to achieve relative fixation of the docking ring 3. Through the action of the first slot 31, the cylinder 1 is supported. Then, the end cap 2 is inserted into the second slot 32 and fixed by the base support 5 to achieve the connection between the end cap 2 and the cylinder 1. This ensures that the cylinder 1 and the end cap 2 can maintain structural stability before and after disassembly and assembly, effectively improving the stability of the structure, without affecting the internal flow field of the experimental model, and ensuring the successful implementation of the visualization experiment of the flow field in the lower chamber of the reactor.

[0020] Furthermore, in a specific implementation, the base support 5 provided in this embodiment of the present invention includes a support ring 51 and reinforcing ribs 52. At least three reinforcing ribs 52 are provided, and the reinforcing ribs 52 are centrally symmetrically distributed with respect to the support ring 51. This enhances the supporting capacity and ensures stability and safety under high pressure conditions. Simultaneously, the centrally symmetrical distribution of the reinforcing ribs 52 makes the load distribution more uniform, improves the structure's stress resistance, and reduces the risk of failure.

[0021] Preferably, one end of the reinforcing rib 52 is bolted to the butt ring 3, and the other end of the reinforcing rib 52 is welded to the support ring. The inner wall of the reinforcing rib 52 is tightly fitted to the outer wall of the end cap 2. This ensures that the inner curvature of the reinforcing rib 52 is consistent with the outer curvature of the end cap 2, ensuring uniform stress distribution and preventing stress concentration from damaging the end cap 2.

[0022] Preferably, the mounting positions of the connecting rod 4 on the mating ring 3 are vertically aligned with the positions where the reinforcing ribs 52 are arranged. This allows part of the tensile force borne by the end cap 2 under the impact of coolant to be transferred to the mating ring 3 and the connecting rod 4, preventing the end cap 2 from deforming under internal pressure and coolant impact, improving the force transmission efficiency, effectively resisting possible external impacts or internal pressure changes, and further enhancing the overall structural stability.

[0023] Furthermore, in a specific implementation, the docking ring 3 provided in this embodiment of the present invention has a spacer ring 33 between the cylinder 1 and the end cap 2. The inner wall of the spacer ring 33 is smoothly connected to the inner walls of both the cylinder 1 and the end cap 2. Specifically, the spacer ring 33 is integrally formed with the docking ring 3, serving as a separator. The smooth connection between the inner wall of the spacer ring 33 and the inner walls of the cylinder 1 and the end cap 2 ensures the formation of a continuous and unchanging flow boundary on the inner wall surfaces of the cylinder 1, the docking ring 3, and the end cap 2, without interfering with the internal flow field, thus helping to reduce friction and maintain good hydrodynamic performance.

[0024] Furthermore, in a specific implementation, a first sealing ring 61 that contacts the outer wall of the cylinder 1 is provided in the first slot 31 provided in this embodiment of the present invention, and a second sealing ring 62 that contacts the outer wall of the end cap 2 is provided in the second slot 32. The first sealing ring 61 and the second sealing ring 62 form a double seal, which helps to reduce the risk of leakage, improve sealing performance, ensure the safe use of the container, and improve the safety and reliability of the system.

[0025] Furthermore, in specific implementations, the docking ring 3, connecting rod 4, and base 5 provided in this embodiment of the present invention are all made of metal materials. This ensures the rigidity and durability of the docking fixing structure, provides sufficient tensile strength, and prevents the end cap 2 from deforming or failing under high internal pressure.
