Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical polypeptide products, in particular to a condenser liquid pipeline. Background Art

[0002] The main function of the condenser for polypeptide purification is to use a low-temperature environment to quickly cool the water in the polypeptide solution to form ice crystals, and to use a vacuum environment to directly transform the ice crystals from solid to gas, thereby removing the water and achieving the drying and purification of the polypeptide. Specifically, the working principle of the condenser for polypeptide purification is based on two processes: low-temperature condensation and sublimation drying. During the low-temperature condensation process, the polypeptide solution is rapidly cooled, and the water therein forms ice crystals at low temperatures; during the sublimation drying process, the ice crystals directly transform from solid to gas under vacuum conditions, thereby removing the water and achieving the drying and purification of the polypeptide. The condenser liquid pipeline is usually connected by welding and flange connection. When the two pipe body joints are connected by conventional flanges, the sealing gasket is prone to aging after long-term use, which in turn affects the sealing of the pipeline connection. To this end, we provide a condenser liquid pipeline to solve the above problems. Utility Model Content

[0011] The utility model proposes a condenser liquid pipeline, including a tube body 1 and a tube body 2, a sleeve 3 is welded to one end of the outer wall of the tube body 1, a wedge-shaped groove 5 is provided at the inner connection between the tube body 1 and the sleeve 3, a sealing ring 4 is provided in the wedge-shaped groove 5, the wedge-shaped groove 5 is annular as a whole, and the annular cross-section is triangular, so that the sealing ring 4 can be stably located at the connection between the tube body 1 and the tube body 2, ensuring the sealing performance, and the tube body 2 can be embedded in the inner cavity of the sleeve 3 and tightly connected with the sealing ring 4. Fitting, the sleeve 3 and the tube body 2 are connected by a fixing component. In actual use, the inner and outer diameters of the tube body 1 and the tube body 2 are the same, and the sleeve 3 can be loosely matched with the tube body 1 and the tube body 2. The fixing component includes a flange 1 6, a flange 2 7 and a bolt 8. The flange 1 6 is welded to the outer wall of the sleeve 3, and the flange 2 7 is welded to the outer wall of the tube body 2. A sealing gasket 9 is arranged between the flange 1 6 and the flange 2 7. The flange 1 6 and the flange 2 7 are fixedly connected by bolts 8.
