Due to the inherent structure andspecialThe sealing method is increasingly being applied in various industries. Below we will provide a comprehensive introduction to inflatable seals, allowing you to have a deeper understanding of inflatable seals.

外形和性能Inflatable sealing ring is a hollow sealing ring made of rubber, with a valve installed on the ring body, connected to a gas source, and used for pressurization and pressure relief. After inflation, the ring expands elastically; After deflation, the ring body shrinks back to its original shape. This working method can provide greater interference to achieve sealing, which is its biggest feature. There are various cross-sectional shapes of inflatable sealing rings, which can be designed according to specific needs. The shape can be made into circles, square circles, and linear capsules.

working principleThe construction of inflatable sealing rings relies on inflation to exert sealing effect. Due to the flexibility of rubber, the rubber hollow ring after inflation and expansion has plasticity. After the expansion surface comes into contact with the sealing surface, a flexible curve deformation occurs, which can seal the gap in a straight or curved shape around the perimeter (several meters to several hundred meters). After venting, the sealing ring instantly returns to its original shape, and the equipment gap reappears. It can quickly and efficiently achieve sealing and unsealing, and can be used up to 1 million times for frequent inflation and deflation. In working condition, due to the gas pressure inside the ring, the sealing strength is high, resulting in high airtightness and good sealing effect.
