三、進(jìn)口低溫截止閥應(yīng)用：

進(jìn)口低溫截止閥是應(yīng)用于低溫工況下的截止設(shè)備，一般工況溫度在-100℃以下.低溫工業(yè)在工業(yè)領(lǐng)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(yùn)輸，工業(yè)上一般用降溫和壓縮的方法將氣化天然氣轉(zhuǎn)化為液化天然氣（LNG），在標(biāo)準(zhǔn)大氣壓下的沸點(diǎn)是-162℃，氣化后體積為液態(tài)時(shí)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(mén)與重要截止設(shè)備，對(duì)其密封結(jié)構(gòu)的設(shè)計(jì)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.

四、進(jìn)口低溫截止閥產(chǎn)品簡(jiǎn)介：

德國(guó)LOCKE洛克進(jìn)口低溫截止閥，也叫LNG截止閥，液氮截止閥，液氧截止閥，液氬截止閥，液化天然氣截止閥，是指用于低溫液體（主要包括液氧、液氮、液氬、液態(tài)烴和液化天然氣等LO2、LN2、LAR、LNG等）貯運(yùn)設(shè)備的管理系統(tǒng)的截止閥，具有開(kāi)關(guān)靈活、密封可靠的特點(diǎn)，也可用于其他低溫和深冷介質(zhì)的管理系統(tǒng)。

The low temperature stop valve imported from Germany Locke, also known as LNG stop valve, liquid nitrogen stop valve, liquid oxygen stop valve, liquid argon stop valve and liquefied natural gas stop valve, refers to the stop valve used in the management system of low-temperature liquid (mainly including LO2, LN2, LAR, LNG, etc.) storage and transportation equipment of low-temperature liquid (mainly including liquid oxygen, liquid nitrogen, liquid argon, liquid hydrocarbon and liquefied natural gas, etc.), with the characteristics of flexible switch and reliable sealing Point, can also be used for other low temperature and cryogenic medium management system.
