Haisheng Rubber takes you to know O-rings and gaskets

O形圈与垫片 广泛用于工业与生活中,但可能我们会纠结到底哪种的密封性比较好呢? With the continuous development and progress of the social age, O-rings and gaskets in today's society are widely used in industry and life, but what kind of tightness may we tangled in the end? Haisheng Rubber takes everyone to understand their similarities and differences.

O-rings are the same as gaskets:

Both meet this implicit condition: when the sealing contact pressure is greater than the pressure of the sealed medium, the sealing effect is maintained;

O形圈被顶开,介质出现大量泄漏。 When the sealing contact pressure is less than the pressure of the medium to be sealed, the gasket or O-ring is ejected, and a large amount of medium leakage occurs.

The difference between O-ring and gasket:

Flat gasket seals consist of gaskets, flanges and bolts, forming a complex statically indeterminate system; the contact pressure of the seal is provided by the deformation of the bolts. The contact pressure distribution when the flat gasket is working is uniform. When the medium pressure fluctuates and is greater than the contact pressure, leakage may occur.

In contrast: for constant pressure conditions, both can be matched; but for variable conditions, when the pressure rises, it may exceed the contact pressure range of the gasket, and the medium ejects the sealing gap and leaks. The O-ring is completely burst.

O形圈 既可用于静密封,也可用于往复直线运动的动密封。 In application, gaskets are only used for static sealing, and O-rings can be used for both static sealing and dynamic sealing with reciprocating linear motion.

O形圈的设计只要根据沟槽尺寸确定就行,既简单又靠谱,方便实用。 In design, the traditional method of gasket seal design is not strict enough, and the new flange gasket design specifications are in the process of experimental research; the design of the O-ring is only required to be determined according to the groove size, which is simple and reliable, convenient and practical.

O形圈还是垫片,最重要的是合适,能被更好的发挥其密封作用。 In fact, whether it is an O-ring or a gasket, the most important thing is that it can be used to better exert its sealing effect.
