密封结构原理与槽垫密封结构

提出了密封结构原理源于但确完全不同于ASME法规的理念。根据该原理提出的槽垫密封结构，其密封维持系数m大于l，具有自密封性，可利用垫材的冷流特性加强密封，因此，可随容器体通过2倍额定工作压力的保证压力测试和4倍额定工作压力的破裂压力测试，加之“微观线后

Seal-designing Principle and Gland Gasket Seals

The seat-designing principle proposed here originates in ASME Code but differs from the ASME Code＇s. The gland gasket seals proposed according to the principle have a seal-maintaining factor m bigger than one or have a self-energized ability so as to be able to make use of the cold flow property of gasket material to strengthen sealing,and therefore can passes a proof pressure test of 2 times the rating and a burst pressure test of 4 times the rating for any pressure vessel using these seals,and can meet the need of sealing connections by using a new sealing structure of ＂microline contact followed by a micro-surface contact＂.
