AI Technical Summary
In high-temperature environments, the sealing ring material is prone to melting, leading to sealing failure. Existing technologies require frequent replacement of the sealing ring, increasing costs and operation time, and cannot provide a long-lasting and stable seal in high-temperature environments.
A gas-filled sealing ring with a cooling function is designed. Low-temperature gas is introduced into the sealing ring through a gas circulation system and circulated to cool it down. Combined with multiple sets of gas valves and fixing mechanisms, the sealing ring can be stably cooled and installed in high-temperature environments, and can be adapted to sealing parts of different shapes.
It achieves continuous and stable cooling of the sealing ring in high-temperature environments, reduces the frequency of sealing ring replacement, lowers costs and operating time, and ensures the durability of the sealing effect.
