二、進(jìn)口液氮截止閥產(chǎn)品簡介：

德國LOCKE洛克品牌-進(jìn)口液氮截止閥，也叫超低溫截止閥，液氮截止閥，液氮低溫截止閥，液氮不銹鋼截止閥，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)。

液氮（常寫為LN2），是氮?dú)庠诘蜏叵滦纬傻囊后w形態(tài)。氮的沸點(diǎn)為-196°C，在正常大氣壓下溫度如果在這以下就會形成液氮；在工業(yè)中，液態(tài)氮是由空氣分餾而得。先將空氣凈化后，在加壓、冷卻的環(huán)境下液化，借由空氣中各組分之沸點(diǎn)不同加以分離。氦氣最先泄出(且未被液化)，接著就是占空氣中78.09%的氮?dú)猓賮硎钦?/font>20.95%的氧氣，最后是占空氣中0.93%的氬氣。

German locklock brand imported liquid nitrogen stop valve, also known as ultra low temperature stop valve, liquid nitrogen stop valve, liquid nitrogen low temperature stop valve, liquid nitrogen stainless steel 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, 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.

Liquid nitrogen (usually written as LN2) is the liquid form of nitrogen formed at low temperature. The boiling point of nitrogen is - 196 ° C. under normal atmospheric pressure, if the temperature is below this, liquid nitrogen will be formed; in industry, liquid nitrogen is obtained by fractional distillation of air. The air is first purified and then liquefied in a pressurized and cooled environment, and separated by the different boiling points of each component in the air. Helium was first released (and not liquefied), followed by nitrogen (78.09%), oxygen (20.95%), and argon (0.93%).

三、進(jìn)口液氮截止閥產(chǎn)品特點(diǎn)：

1、在低溫介質(zhì)下具有長時(shí)間工作的能力;

2、直接與低溫介質(zhì)接觸的組合件具有防爆和防火結(jié)構(gòu);

3、在低溫工作的材料要保證其低溫性能,以防止摩擦件擦傷;

4、在低溫及無油潤滑的情況下，具有良好的耐摩性。

1. It can work for a long time in low temperature medium;

2. The assembly directly contacting with low temperature medium has explosion-proof and fireproof structure;

3. The material working at low temperature should ensure its low temperature performance to prevent abrasion of friction parts;

4. It has good friction resistance at low temperature and without oil lubrication.
