Abstract

It was determined experimentally that to provide complete sealing, the value of the contact pressure on the sealing surface must be three times greater than the internal pressure. The tightness of flange connections is provided by creating the necessary pressure on the sealing surfaces of the flanges. Moreover, the required specific pressure is created in the seals by tightening the bolts fastening the flanges. The amount of leakage is influenced by the surface roughness and the accuracy of the manufacturing of the sealing elements.

摘要

实验确定，要提供完全密封，密封表面上的接触压力值必须大于内部压力的三倍。法兰连接的密封性是通过在法兰的密封表面上产生必要的压力来提供的。此外，通过拧紧紧固法兰的螺栓，在密封件中产生所需的比压。泄漏量受密封元件的表面粗糙度和制造精度的影响。
