Custom Size Inflatable Silicone Rubber Seal for Sealing Chemical Processing Equipment

Inflatable O ring gaskets mainly used in big machine equipment hatch door gap, Due to the influence of processing and assembly accuracy, or the thermal expansion and contraction deformation caused by the change of environmental temperature, the gap that needs to be sealed is also inconsistent or changed. The range of change is generally more than 3-5mm, sometimes even up to Above 10mm, it is difficult to achieve the ideal sealing effect with ordinary sealing strips. In this case, Inflatable sealing ring is made to meet it.

normal situation The retractable part is contracted in the concave groove. When the air bag of the sealing ring is inflated through the inlet and exhaust nozzles, the air bag of the sealing ring is deformed due to the internal pressure, and the middle recessed part expands outwards, thus playing a sealing role.
