[0001] The application belongs to the technical field of vacuum pipe bodies, and particularly relates to a reinforcing ring for corrugated pipe welding. BACKGROUND

[0002] Vacuum corrugated pipes are used to realize expansion, bending and absorption of different displacements in ultrahigh vacuum systems, and are widely applied to fields such as semiconductor microelectronics, solar photovoltaics, LED photoelectricity and FPD film coating.

[0003] In the prior art, slotting is used for welding connection, and high temperature generated by welding is directly transmitted to the circular ring body, and due to the thermal characteristics of metal, high temperature is easy to cause deformation of the metal, so that deviation occurs when subsequent components are installed. CONTENT OF THE UTILITY MODEL

[0004] The utility model aims at the above problems, and provides a reinforcing ring for corrugated pipe welding which can solve the above technical problems.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] The reinforcing ring for corrugated pipe welding comprises a circular ring body, and a convex ring for fixing a precision pipe on any annular plane in the direction of the central axis of the circular ring body, and the precision pipe is at least partially inserted into the convex ring.

[0007] Further, the outer diameter of the precision pipe inserted into the convex ring is equal to the inner diameter of the convex ring.

[0008] Further, the precision pipe inserted into the convex ring is fixedly connected with the convex ring by brazing.

[0009] Further, the outer diameter of the convex ring is smaller than the outer diameter of the circular ring body.

[0010] Further, the thickness of the convex ring in the direction of the central axis is smaller than the thickness of the circular ring body.

[0025] Example 1

[0026] like Figure 1 As shown, the reinforcing ring for corrugated pipe welding includes a circular ring 1 with two parallel annular planes 10 about the central axis S. A weldable convex ring 3 is provided on either annular plane 10. A corrugated pipe is connected to the other annular plane 10 by welding or other means. The reinforcing ring for corrugated pipe welding is connected to an external precision pipe fitting 2 through the weldable convex ring 3. The outer diameter of the weldable convex ring 3 is smaller than the outer diameter of the circular ring 1. One end of the precision pipe fitting 2 is partially inserted into the weldable convex ring 3. The weldable convex ring 3 will at least partially melt and be fixedly connected to the precision pipe fitting 2 under the high temperature of welding. It is worth noting that the precision pipe fitting 2 and the weldable convex ring 3 are seamlessly connected to prevent the possibility of medium leakage during use.

[0027] like Figure 1 As shown, regarding the aforementioned reinforcing ring for bellows welding, compared to existing technologies, as... Figure 2As shown, the precision pipe 2 is welded and fixed on the annular plane 10 of the toroidal body 1, and the existing improvement is that the connecting part, i.e. the soldering fusible convex ring 3, is arranged on the annular plane 10 of the toroidal body 1. In the prior art, the groove is welded and connected, and the high temperature generated by welding is directly transmitted to the toroidal body 1. Due to the thermal characteristics of metal, high temperature is easy to cause the deformation of metal, so that the deviation occurs when the subsequent installation components are installed. In the present application, the processing technology is optimized, and the soldering fusible convex ring 3 is used to replace the groove connection. In the soldering process, most of the heat will not be transmitted to the toroidal body 1, so that the shape of the toroidal body 1 will not change, and the installation accuracy is improved. In order to ensure that the soldering fusible convex ring 3 can be partially melted and connected with the precision pipe 2 in the high temperature environment; specifically, the precision pipe 2 inserted in the soldering fusible convex ring 3 has an outer diameter smaller than the soldering fusible convex ring 3, and the purpose is to ensure that the precision pipe 2 can be stably and smoothly inserted in the soldering fusible convex ring 3, and has a certain fault tolerance space.

[0028] The thickness of the soldering fusible convex ring 3 in the direction of the central axis S is smaller than the thickness of the toroidal body 1. The thinner soldering fusible convex ring 3 is easier to melt in the welding process, and forms a uniform welding joint, reduces defects in the welding seam, such as pores and poor fusion, and ensures the strength and reliability of the welding structure. At the same time, the smaller thickness can reduce the heat effect generated in the welding process, and reduce the risk of hardening or deformation of the material caused by overheating.

[0029] Specifically, regarding the toroidal body 1, the reinforcing ring for the corrugated pipe welding is further provided with a conical hole 11 penetrating the toroidal body 1 in the direction of the central axis S. The conical hole 11 communicates with the parallel annular planes 10, so that the medium can enter the precision pipe 2 connected to another annular plane 10 from the corrugated pipe connected to one annular plane 10. The inner diameter of the soldering fusible convex ring 3 on the same side is at least greater than or equal to the hole diameter of the conical hole 11. The conical hole 11 can guide the airflow, and the airflow can smoothly pass through the conical hole 11 from the corrugated pipe to the precision pipe 2.

[0030] Specifically, the conical hole 11 can be any one of a stepped conical hole and a continuous conical hole. In this embodiment, the continuous conical hole is specifically described. The soldering fusible convex ring 3 is coaxially distributed with the conical hole 11, which can ensure the welding defects caused by position deviation in the welding process, thereby improving the welding quality and connection strength. At the same time, the inner diameter of the precision pipe 2 is equal to the hole diameter of the conical hole 11, which can achieve better overall cooperation. This precise coupling effectively reduces the gap and improves the tightness between components, ensuring the stability of the components during operation.

[0031] Embodiment two

[0032] The structure and principle of the embodiment are basically the same as those of Embodiment One, and the different structure is that, for the reinforcing ring for the bellows welding in Embodiment One, the embodiment describes other main components about the reinforcing ring for the bellows welding.

[0033] As shown in Figure 1 The cylindrical surface 12 of the torus body 1 is further provided with an annular cut groove 120, which divides the cylindrical surface 12 of the torus body 1 into a bellows welding connecting part 13 and a mesh ring welding part 14. The thickness of the bellows welding connecting part 13 is less than that of the mesh ring welding part 14. The annular cut groove 120 is any one of a V-shaped groove and a U-shaped groove. Specifically, the annular cut groove 120 of the embodiment is a V-shaped groove.

[0034] The groove depth of the annular cut groove 120 is 1 / 2-1 / 3 of the distance from the inner diameter to the outer shape of the torus body 1, which can maintain the overall rigidity and strength of the torus body. A too deep cut groove can reduce the structural strength, causing the material to become brittle or damaged, while a moderate depth can reduce the weight while ensuring that the torus body is not easily deformed. Appropriate cut groove depth helps to increase the surface area, thereby improving heat dissipation. When the equipment is working at high temperature, the cut groove can effectively help to reduce the overall temperature.

[0035] Specifically, the mesh ring welding part 14 is fixedly connected with a metal mesh sleeve 4 as shown in Figure 3 As shown in Figure 3 The metal mesh sleeve 4 further includes two mesh rings 5 respectively sleeved at both ends of the metal mesh sleeve 4. The end of the mesh ring 5 away from the metal mesh sleeve 4 is extended and sleeved outside the torus body 1, and the mesh ring 5 and the torus body 1 are connected by welding. The equal-diameter structure can prevent airflow from forming an obstacle during walking and causing turbulence.

[0036] The specific embodiments described herein are merely illustrative of the spirit of the utility model. Those skilled in the art to which the utility model belongs can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the utility model or exceed the scope defined by the appended claims.
