Gasket seal is the main sealing form of the releasable links in industrial installations such as pressure vessels, process equipment, power devices and connecting pipes. It is usually composed of flanges, bolts, nuts and gaskets, which are called bolt flange connections. The operating conditions for the gaskets are very complex, and there are a wide variety of fluid media to be sealed. It is an important and difficult task for the factory to prevent liquids or gases from leaking out through the gasket seal joints. For the seal principle of the gasket, we will briefly introduce it here: Leakage means the medium flows from the interior of the limited space to the outside, or enters the limited space department from the outside, and people do not want to happen. To reduce leakage, it must be a large degree of engagement of the contact surface, that is, to reduce the cross-sectional area of ​​the leakage passage, increase the leakage resistance, and make it larger than the leakage driving force. Applying a tight load on the sealing surface to produce a compressive stress can increase the contact level of the sealing surface. When the stress is increased enough to cause significant plastic deformation of the surface, the clearance of the sealing surface can be filled to block the leakage path. The purpose of using the gasket is to use the material of the gasket under the action of the compressive load to easily produce the plastic deformation characteristics, so that the smile of the flange sealing surface can be filled and the unevenness can be achieved, so as to achieve sealing.
