High vacuum type heat insulation double-wall pipe support

The utility model discloses a high vacuum type heat insulation double-wall pipe support which comprises an inner pipe, an outer pipe and a supporting plate, the inner pipe is sleeved with the inner side of the supporting plate, the outer side of the supporting plate abuts against the outer pipe, a plurality of limiting blocks are arranged on the two sides, corresponding to the supporting plate, of the inner pipe in the axial direction, and the limiting blocks are distributed along the circumference. According to the utility model, the structure is simple, the manufacturing cost is low, the welding work is reduced during assembly, the supporting plate is prevented from being directly welded on the inner pipe, and the potential possibility of safety accidents such as deformation, welding cracks and the like caused by welding is reduced. 本实用新型公开了一种高真空型绝热双壁管支撑，包括内管、外管和支撑板，所述支撑板的内侧套在内管上，支撑板的外侧抵在外管上，所述内管沿轴向对应支撑板的两侧均设置有若干限位块，若干所述限位块沿圆周分布，限位块与内管之间断续焊固定，本实用新型结构简单，制作成本低，在装配时减少焊接工作，壁免了支撑板直接焊接在内管上，降低了焊接引起的变型、焊接裂纹等安全事故发生的
