You must not know these things about graphite gaskets!

Graphite gaskets are widely used in industrial production and are well known by many people. I believe many people have heard of graphite gaskets, but some people must not know the sealing mechanism and deformation equation of graphite gaskets. This sounds professional. The words with strong terms are a bit scratchy, don't worry, today is to take everyone to learn about these things about graphite gaskets!

Mechanical equipment can be divided into two parts: static seal and dynamic seal according to the relative movement of the sealing surface. Static seal is a common seal in daily production, such as pipe flanges, threaded connections, pressure vessel and cover seals, etc. Principle, static seal can be divided into bolt flange connection gasket seal, self-tightening seal, thread connection gasket seal and sealant seal, etc. Among them, bolt flange connection gasket seal is the most widely used type of static seal. form. The research work on this sealing structure mainly focuses on two aspects: on the one hand, the performance test of the sealing material, the research on the preparation method of the material, and the scientificity and accuracy of the experimental instruments and methods; on the other hand, A lot of analysis work has been done on various causes of seal failure. For gaskets of different materials and different forms, the factors affecting the leakage rate have been studied.

To prevent fluid leakage, the basic method used is to increase the resistance to fluid flow at the seal. When the resistance of the medium through the seal is greater than the pressure difference between the two sides of the seal, the medium is sealed. The resistance of the medium through the seal is achieved by means of the specific pressure applied on the pressing surface. The greater the specific pressure of the seal on the pressing surface, the greater the resistance of the medium passing through the seal, which is more favorable for sealing.
