Further, for the sacculus in being horizontally disposed with, balloon interior is provided with support bar in the arrangement of comb dentation.Sacculus has
Certain elastic reaction, support bar play support effect, and the two plays resilient support effect within the specific limits, is advantageous to improve
The elastic performance of packed layer.
Further, the double layer sector structure that the cushion pad is upper cushion and lower cushion clamping is formed, upper buffering
It is raised that zigzag buffering is staggeredly equipped with pad and the interface of lower cushion.The special construction of cushion pad increases packed layer
Elastic anti-compression properties, in use, cushioning effect is played, can effective compensation thermal shock (thermal cycle), pressure oscillation etc.
Sealing Stress caused by factor lacks, and also ensures sealing ring from overloading conquassation.
Further, the upper cushion is arranged to the sector structure that several layers of arc form without asbestos laying.With groove
Coordinate tight ness rating high, reduce the space inside sealing ring, reduce parts for maintenance, the workload safeguarded, while favorable sealing property.
Further, the lower cushion is arranged to " V " font compression spring.Elasticity is with the obvious advantage, plays shock resistance, delays
Punching acts on so that cushion pad has stronger sealing screen resilience.
The beneficial effects of the utility model are：
The inner ring of sealing ring can effectively improve the heat resistance of sealing ring；Reliably closely it can be combined with connector；Filling
Layer compressive resistance is stronger, and sacculus and cushion pad have high resilience, can effective compensation it is tight caused by thermal shock and pressure oscillation
The generations such as fixing bolt strain and caused by Sealing Stress lose；Metal outer shroud plays the role of positioning when sealing gasket is installed, and improves close
The intensity of seal ring and pressure-resistant performance.Therefore, sealing ring of the present utility model can meet the seal request of HTHP, and and can exists
Ensure that Sealing Stress is constant, ensures the safe and reliable of sealing under alternate load.
