Product details
Reinforced fabric inflatable seal exhibit significant advantages in airtightness. These advantages stem from their unique design, material selection, and manufacturing process, enabling them to meet the stringent airtightness requirements of various applications. The following is a detailed description of their airtightness characteristics:
I. Structural Design Features
* Seamless Integrated Structure: The integral molding process ensures that the seal is a single piece, without seams or joints, fundamentally eliminating potential channels for gas leakage. This structure avoids airtightness problems caused by poor splicing or assembly errors in traditional seals.
Inflation-Induced Self-Adaptive Sealing: The seal features an internal inflation chamber. After inflation, its surface can tightly conform to the minute irregularities and shapes of the sealing surface, forming a continuous airtight barrier. This self-adaptive capability allows it to maintain a highly efficient seal even on complex sealing surfaces.
Multi-Lip or Corrugated Design: Some seals employ a multi-lip or corrugated structure, forming multiple sealing lines after inflation, further enhancing airtightness. Even if a minor leak occurs at one sealing line due to external force or wear, the other sealing lines can still maintain their sealing effect.
II. Material Selection Characteristics
**High-Elasticity, Aging-Resistant Materials:** Utilizing highly elastic materials such as silicone rubber and fluororubber, these materials rapidly return to their original shape after inflation and are resistant to permanent deformation or hardening over long-term use, thus maintaining stable airtightness.
**Low Gas Permeability Materials:** The materials themselves have extremely low permeability to gases (such as oxygen and nitrogen), effectively preventing gas penetration through the material body and further enhancing overall airtightness.
**Chemical Corrosion Resistant Materials:** In chemical or special gas environments, Inflatable seal materials must resist chemical corrosion to prevent airtightness degradation. For example, fluororubber exhibits excellent resistance to various chemical media.
III. Manufacturing Process Characteristics
**Precision Molding:** The molding process ensures high dimensional accuracy and a smooth surface finish, reducing the risk of gas leakage due to surface defects or dimensional deviations.
**Uniform Inflation Chamber Design:** The optimized structural design of the inflation chamber ensures uniform pressure distribution after inflation, avoiding localized stress concentration or insufficient expansion, thereby maintaining overall airtightness.
Strict Quality Inspection
Inflation Pressure Test: During the manufacturing process, the seals undergo an inflation pressure test to verify their airtightness at the design pressure.
Helium Leak Detection: Using helium as a tracer gas, minute leaks are detected by high-sensitivity leak detection equipment to ensure that products meet airtightness standards before leaving the factory.
IV. Airtightness Performance
Long-Term Stability: During long-term use, the seals maintain airtightness and are not easily leaked due to environmental factors (such as temperature changes, vibration) or mechanical stress.
Wide Pressure Range Adaptability: By adjusting the inflation pressure, Rubber Inflatable seals can maintain airtightness under different pressure conditions (such as vacuum or high-pressure environments) to meet diverse application requirements.
Resistant to Dynamic Sealing: During equipment operation, the seals automatically adjust to minute movements or deformations of the sealing surface, maintaining a dynamic sealing effect, suitable for vibration or reciprocating motion scenarios.
