[0026] As shown in Figures 1 to 7 The present application embodiment provides a large-flow high-temperature-resistant and vacuum pressure pipeline element, which comprises a steel shell 1, a flange plate 2 welded at both ends of the steel shell 1; an inner lining assembly for high-temperature-resistant and pressure-resistant pipeline assembly is arranged in the steel shell 1. The inner lining assembly can make the pipeline assembly have better high-temperature resistance and can enhance the pressure resistance of the pipeline assembly, so that the pipeline assembly will not crack and cause chemical medium leakage under pressure during normal operation. The inner lining assembly comprises a metal fixing strip 3 and a metal porous profile 4 arranged in the steel shell 1, a tetrafluoroethylene resin layer 5 arranged between the metal porous profile 4, the metal fixing strip 3 and the steel shell 1, the tetrafluoroethylene resin layer 5 being arranged between the metal porous profile 4, the metal fixing strip 3 and the steel shell 1 and completely covering the metal porous profile 4, and a connecting assembly arranged on the flange plate 2 for facilitating installation of the pipeline assembly. The connecting assembly can make the pipeline assembly more convenient to install and connect than the traditional method of connecting and fixing by multiple bolts during use. The connecting assembly comprises a threaded rod 6 rotatably connected to the flange plate 2, a pressing block 7 threadedly connected to the threaded rod 6, a connecting disc 8 arranged on one side of the flange plate 2 for cooperating with the flange plate 2, and the connecting disc 8 being integrated with the external pipeline, so as to complete the connection between the pipeline assembly and the external pipeline through the connecting disc 8 and the flange plate 2.

[0027] As shown in Figures 1 to 7As shown, specifically, the number of metal fixing strips 3 are equidistantly welded in the inner cavity of the steel shell 1, the metal porous profile 4 is welded on the metal fixing strip 3, the pipeline assembly steel shell 1 is equidistantly welded and fixed inside by the metal fixing strip 3, the metal porous profile 4 is welded on the metal fixing strip 3 inside the steel shell 1 and ensures firmness, therefore, by welding the metal fixing strip 3 and the metal porous profile 4 inside the steel shell 1, the strength of the pipeline assembly during use can be strengthened, the structure is stable and durable, has good mechanical properties, can withstand vacuum negative pressure environment, maintains its shape and function, and the metal porous profile 4 and the polytetrafluoroethylene resin layer 5 are high-pressure pressed and closely attached to the inner wall of the pipeline assembly steel shell 1, so that they are fused between the metal porous profile 4, the metal fixing strip 3 and the steel shell 1 to form the polytetrafluoroethylene resin layer 5, and the polytetrafluoroethylene resin has excellent high temperature resistance, so that the pipeline assembly has excellent high temperature resistance inside during use, so that the strength of the pipeline assembly does not decrease when working in a high temperature environment, so that deformation, rupture and other phenomena do not occur.

[0028] As Figures 1 to 7As shown, specifically, the pipeline assembly is connected with the external pipeline through the connecting flange plate 2 and the connecting plate 8, thereby completing the connection between the pipeline assembly and the external pipeline. The connecting plate 8 is provided with a through slot 12 and an extrusion slot 13 matched with the pressing block 7, and the through slot 12 and the extrusion slot 13 are arranged perpendicular to each other. The connecting plate 8 is provided with a limiting slot 14, and a sliding block 15 for limiting the pressing block 7 is slidingly connected in the limiting slot 14. The sliding block 15 and the connecting plate 8 are fixedly connected with a spring 16. The threaded rod 6 is fixedly connected with a baffle 17 for preventing the pressing block 7 from falling off. The flange plate 2 is gradually moved close to the connecting plate 8, and the sliding block 15 is pulled to move in the limiting slot 14. At this time, the spring 16 is contracted under stress to generate a reaction force. The threaded rod 6 on the flange plate 2 and the pressing block 7 on the threaded rod 6 pass through the through slot 12 on the connecting plate 8. After the pressing block 7 passes through the through slot 12, the threaded rod 6 is rotated on the flange plate 2 and drives the pressing block 7 to rotate. After the pressing block 7 is rotated to match the extrusion slot 13, the pipeline assembly is moved so that the pressing block 7 gradually enters the extrusion slot 13, and the sliding block 15 is loosened to move back under the reaction force of the spring 16, so that the sliding block 15 limits the pressing block 7, and the pressing block 7 cannot move in the extrusion slot 13. The threaded rod 6 is fixedly connected with a rotating block 18, and the rotating block 18 is provided with a hexagonal groove 19. Then, the rotating block 18 is rotated to rotate the threaded rod 6. At this time, the threaded rod 6 is rotated and the pressing block 7 remains stable and cannot rotate in the extrusion slot 13. The pressing block 7 moves along the threaded rod 6 to gradually move close to the flange plate 2, so that the pressing block 7 gradually extrudes the connecting plate 8 to move close to the flange plate 2. The flange plate 2 is provided with a protruding ring 9, and the connecting plate 8 is provided with a ring groove 10 matched with the protruding ring 9. The ring groove 10 is provided with a sealing ring 11. In the process of gradually moving the connecting plate 8 close to the flange plate 2, the protruding ring 9 gradually enters the ring groove 10, and the connection between the connecting plate 8 and the flange plate 2 is sealed under the cooperation of the sealing ring 11. Under the gradual rotation of the threaded rod 6, the connecting plate 8 gradually moves close to the flange plate 2 and completes the connection. Conversely, when disassembling, the threaded rod 6 is rotated in the opposite direction to make the pressing block 7 gradually move away from the flange plate 2, so that the connecting plate 8 can be separated from the flange plate 2. Then, the sliding block 15 is pulled to no longer limit the pressing block 7, so that the pressing block 7 is separated from the extrusion slot 13 by moving the connecting plate 8. The threaded rod 6 is rotated to drive the pressing block 7 to rotate to the position matched with the through slot 12. Then, the connecting plate 8 can be moved to make the pressing block 7 pass through the through slot 12 to separate the connecting plate 8 from the flange plate 2.
