The sealing principle of the Glay ring (also known as the combined seal ring) is mainly based on its unique structure and material properties.
A Glace ring usually consists of two main parts: an O-ring and an auxiliary sealing element (such as a filling ring or a stop ring). These two parts work together to form an efficient sealing structure.
When the Glay ring is installed in the sealing groove and subjected to pressure, the O-ring will compress and deform and fill in the sealing gap. This compression deformation not only enhances the contact pressure between the O-ring and the sealing groove, but also ensures a tight fit between the ring and the sealing surface. This tight fit effectively prevents the leakage of a medium such as a gas or liquid.
At the same time, auxiliary sealing elements (such as filling rings or retainers) play a further role in improving sealing efficiency. The auxiliary sealing element prevents the O-ring from being squeezed out under high pressure, thereby maintaining the integrity of the seal. In addition, the auxiliary sealing element can also compensate for changes in the sealing clearance caused by temperature changes or mechanical vibration, ensuring the stability of the sealing effect.
In short, the sealing principle of the Glei ring is through the compression deformation of the O-type sealing ring and the use of auxiliary sealing elements to achieve the effective isolation of the medium in the sealing gap and prevent leakage. This sealing structure has excellent sealing performance and reliability, and is widely used in various hydraulic, pneumatic and sealing systems.
