AI Technical Summary

Technical Problem

隐患是当锅炉内部压力失控时，锅炉焊接位因压力过大，锅炉上下盖有可能从焊接面整个裂开，产生巨大的爆炸威力，影响使用的安全

Benefits of technology

[0014]通过在锅炉上设计一个相对容易变形的异形薄弱点，即防爆面，同时配合上锅炉与下锅炉的厚度差异形成强度差异，使得锅炉内压力失控时，能够先从第一异形防爆面与第二异性防爆面的连接处裂开一个小口子，对锅炉进行泄压，避免锅炉整个裂开爆炸的风险。

Abstract

The utility model discloses an anti -explosion special -shaped boiler structure, including the welding together's upper boiler and lower boiler, the upper boiler includes first camber and first special -shaped anti -explosion surface, the lower boiler includes second camber and second special -shaped anti -explosion surface, the thickness of upper boiler is greater than lower boiler, the upside of lower boiler is provided with the flange for realizing welding, the flange is wrapped in the lower extreme of upper boiler, first special -shaped anti -explosion surface is the upper plane structure, second special -shaped anti -explosion surface is the lower plane structure, through the design of one relatively easy deformation's special -shaped weak point on the boiler, namely anti -explosion surface, simultaneously cooperate the thickness difference of upper boiler and lower boiler and form the strength difference, make the boiler internal pressure out of control, can first from the crack of a small hole of first special -shaped anti -explosion surface and second special -shaped anti -explosion surface's junction, carry out pressure relief to the boiler, avoid the risk of the whole crack of boiler explosion.
