What is the role of using flexible waterproofing casing rubber ring?

Flexible waterproof casing rubber waterproofing requirements are very strict. The pipeline is prone to vibration during operation, causing hidden dangers according to climate change. After the installation of flexible waterproof casing, flexible waterproof casing using rubber flexibility to effectively absorb the deformation and displacement of the pipeline vibration, fundamentally solve the hidden dangers of the pipeline.
 
Flexible waterproof casing sealing skeleton structure type is mainly divided into rubber sealing ring and rubber sealing ring, which is commonly used rubber sealing skeleton, the main structure of O-type rubber sealing skeleton, mainly for a variety of conventional occasions sealing T-shaped structure, mainly for a variety of waterproof requirements of high construction projects, to provide good sealing application effect for the pipeline system. Twisting refers to the twisting of the flexible casing rubber along the surrounding in the dynamic sealing state. If the flexible rubber casing is properly assembled and used under suitable conditions, it is not easy to roll or twist in the reciprocating motion state because the contact area of the internal working pipe is larger than the frictional contact area of the sliding surface, and the resistance of the rubber garden itself can prevent twisting.
 
Since static friction is greater than sliding friction, the roughness of the trench surface is generally less than that of the sliding surface, so the friction distribution also tends to keep the rubber garden stationary in the trench.
 
The gap between the flexible waterproof casing and the working tube is not uniform, and there are many reasons why the flexible waterproof casing causes distortion damage. The eccentricity is too large. Uneven diameter of the rubber ring section, due to the rubber ring a week more uneven friction, the rubber ring part of the friction is too large, twisted. Generally speaking, the smaller cross-sectional size of the rubber ring is prone to uneven friction. This is why the diameter of the twisted motion rubber ring is larger than the fixed rubber ring.
