Detailed Description
The utility model provides a vacuum tube for chemical industry, which is further described by referring to the accompanying drawings, as shown in fig. 1, and comprises an inner tube 2, an outer tube 1 and a vacuum tube sealing head 3, wherein the inner tube 2 and the outer tube 1 are made of stainless steel materials, and two ends of the inner tube extend out of two ends of the outer tube for one section; vacuum sealing heads 3 are arranged at two ends of the outer tube 1; the vacuum seal head 3, the inner pipe 2 and the outer pipe 1 form an interlayer cavity, and the vacuum seal head 3 seals the interlayer cavity; after the interlayer cavity of the vacuum pipeline is vacuumized, the vacuum degree is as low as 1X10 -2 Pa. One end close to the outer tube 1 is provided with a vacuumizing valve 5, the middle position of the outer tube 1 is provided with an outer compensator 4, and the outer compensator 4 adopts a corrugated tube as a main body structure and is welded on the outer wall of the outer tube 1. A plurality of layers of composite paper 6 are wound on the outer wall of the inner tube 2, a molecular sieve 7 is arranged in the composite paper 6, a supporting ring 8 is arranged at the same time, the molecular sieve is arranged at one end close to the outer tube, and at least one supporting ring 8 is uniformly arranged on the outer wall of the inner tube 2; is made of epoxy resin material, has lower heat conductivity and plays a role in supporting stainless steelThe function of the outer wall 1. The composite paper 6 can effectively prevent heat radiation, reduce heat loss, and the molecular sieve 7 can adsorb residual trace air for a long time, so that the vacuum time is effectively prolonged.
The outer tube 1 is provided with the outer compensator 4, is made of stainless steel, and is deformed due to the fact that the temperature difference between the inner wall and the outer wall is large when cold and hot fluid is introduced, the inner wall 2 expands with heat and contracts with cold, the outer tube 1 effectively stretches out and draws back under the action of the outer compensator 4, the length consistency of the inner tube and the outer tube is achieved, and weld cracking is avoided. The vacuumizing valve 5 consists of a vacuum suction valve core 501, a vacuum suction valve housing 502 and O-shaped rings 503 and is used for vacuumizing a pipeline, wherein the vacuum suction valve core 501 is provided with the two O-shaped rings 503, and a double-layer sealing effect is achieved.
It should be understood that the above description is not intended to limit the utility model to the particular embodiments disclosed, but to limit the utility model to the particular embodiments disclosed, and that the utility model is not limited to the particular embodiments disclosed, but is intended to cover modifications, adaptations, additions and alternatives falling within the spirit and scope of the utility model.
