低温液体储运罐

自增压液氮罐 1. Self-pressurized Liquid Nitrogen Tank
概述：Overview:
自增压液氮罐是利用罐内少量液氮汽化产生压力，使容器能自动排放液氮，从而为其他容器进行液氮的补充。主要用于运输和贮存液体介质（液氮、液氧、液氩），亦可作为其它制冷装置的冷源。目前广泛应用于工模具行业、畜牧业、医药、半导体、食品、低温化工、航空**、军事等行业和领域。
Self-pressurized liquid nitrogen tank produces pressure by evaporation of little liquid nitrogen so that liquid nitrogen will exhaust itself and complement other containers. It finds its application in the transportation and storage of liquid medium (liquid nitrogen, liquid oxygen and liquid argon) and cold source of other refrigeration equipments. It is now widely used in tool and die industry, animal husbandry, medicine, semi-conductor, food, cryogenic chemical industry, aerospace, military and other industries and areas.

3. 气体采集瓶3. Gas Sampling Bottle
不锈钢采样瓶选用**不锈钢材质，针型不锈钢瓶阀。具有耐腐蚀，耐高压，无渗漏特点。广泛应用于石油化工，电子半导体，科研环保等领域的气、液样品采样和保存。采样前**把采样瓶干燥,抽真空。干燥温度80℃~100℃，干燥时间不少于30分钟。如采样精度高，应用拟充装介质置换。
Sampling bottle of stainless steel is made of stainless steel of fine quality and has a needle-shaped stainless steel bottle valve. It is corrosion-resistant, pressure-resistant, and leakage-free. It finds its wide application in sampling and preservation of gas or liquid samples in petrochemical industry, electronic semi-conductor, scientific research, environmental protection, etc. Before sampling, the sampling bottle must be dry and full of vacuum. Dry temperature is between 80℃ to 100℃, and the drying time is no less than 30 minutes. If sampling precision is high, the optional medium that fills the bottle can be used to substitute.

操作指南：Operation Guide: 
1, 瓶阀开关操作应均衡适当用力，不当操作会损坏阀门。
1.	One should open or close the bottle valve with equal and proper strength; otherwise, valve will be damaged.
2, 液态气体采样介质饱和蒸气压应小于采样瓶工作压力，充装量应根据充装系数确定。
2.	Saturated vapor pressure of liquid gas sampling medium should be lower than working pressure of sampling gas. Filling quantity is determined by filling ratio. 
3, 气态采样充装严禁**压。
3. Overpressure is forbidden for gaseous sampling filling.
