4.Working Principle

●Set:When the pressure inside the central pipe is higher than that of the tubing casing annulus pressure, the glue tube swell and be in contact with the inner diameter of the casing, seal the tubing casing annulus.

●Release: When the pressure inside the central pipe is lower than that of the tubing casing annulus pressure, the seal is released.

5.Product Feature

●The seal adopts the imported hydrogenated nitrile rubber material, can endure high temperature and pressure difference;

●The liquid inlet hole in the central tube uses slotted form, preventing sand and impurity enter the seal, ensure the normal recovery of the seal;

●It is designed with a limit ring, preventing packer of over expansion, ensure the normal recovery of the seal.
