The sealing system of the insulating joint consists of a symmetrical U-shaped sealing ring with two sides. It is tightly assembled with the rigid insulating ring inside the insulating joint and is also squeezed firmly. In the pre-reserved space between the left and right flanges, in order to achieve the best sealing effect, this sealing system is specially designed for the production of insulated joints. It is also the patented technology of Nowakin Company. This insulation The sealing technology of the joint is usually called DSGS, double gasket system.
Advantages of the insulating joint double gasket system: No precise surface finishing or special mechanical tolerances are required. This system can act simultaneously between two symmetrical forging surfaces and metal insulating gaskets. Each component works together to complete the sealing work. Sealing components with larger cross-sectional areas can withstand a series of structural deformations caused by pressure. Due to the large cross-sectional area of ??the sealing ring, the liquid must pass through a considerable distance before side leakage. For this sealed system, all insulating pads are completely wrapped and will not deform when subjected to sudden pressure drops. As the pressure of the pipeline system increases, the sealing system will generate a balanced reverse force to ensure the force balance of the sealing system, and the pressure cycle will not affect the sealing system.
