德国《LOCKE》洛克进口氨用截止阀(Ammonia valve)经常要用到氧气、氮气、氢气、氩气等气体。这些气体一般都是贮存在专用的高压气体中。使用时通过氨用截止阀使气体压力降至实验所需范围,再经过其它控制阀门细调,使气体输入使用系统。常用的减压阀为氨用截止阀,简称氨用阀。 German "LOCKE" Locke imported ammonia globe valve (Ammonia valve) often uses oxygen, nitrogen, hydrogen, argon and other gases. These gases are generally stored in special high-pressure gases. When in use, the gas pressure is reduced to the required range by the ammonia cut-off valve, and then fine-tuned by other control valves to make the gas input into the use system. The commonly used relief valve is the ammonia globe valve, referred to as the ammonia valve.
