FIELD: machine building. ^ SUBSTANCE: in bellows for high pressure vessel circular-like packing is formed between open end of cylinder case of vessel with bottom, wherein raw material comes, and external periphery section of dispersed padding, which closes open end. The bellows has a part bending in radial direction facilitating heat expansion and contraction without impression to prevent stagnation of raw material. ^ EFFECT: elimination of bellows cracking caused by heat extension and contraction and avoiding raw material stagnation. ^ 2 cl, 5 dwg |
