三、進口低溫截止閥應用：

進口低溫截止閥是應用于低溫工況下的截止設備，一般工況溫度在-100℃以下.低溫工業(yè)在工業(yè)領域中占有重要的地位，以天然氣為例，為了使天然氣更加方便運輸，工業(yè)上一般用降溫和壓縮的方法將氣化天然氣轉化為液化天然氣（LNG），在標準大氣壓下的沸點是-162℃，氣化后體積為液態(tài)時的600倍［1］。超低溫截止閥作為低溫工業(yè)用的一種主要閥門與重要截止設備，對其密封結構的設計與研究具有重大的意義。

The imported low-temperature stop valve is a kind of cut-off equipment used in low-temperature conditions, and the temperature is below - 100 ℃. The low-temperature industry plays an important role in the industrial field. Taking natural gas as an example, in order to make the natural gas more convenient for transportation, the gasification natural gas is generally converted into liquefied natural gas (LNG) by cooling and compressing. The boiling point under standard atmospheric pressure is - 162 After gasification, the volume is 600 times that of liquid state. As a main valve and important cut-off equipment used in low-temperature industry, the design and research of its sealing structure is of great significance.
