英国 BAJ Vickers 有限公司已设计出一种供纯空气焦耳—汤姆逊低温冷却装置用的控制阀。用它作为高压气体贮存装置部件,为军事人员将气体贮存容器与热反应装置快速装卸提供方法。此阀可直接装入压力源。该阀非常适合于军用标准需要,可应用于所有陆、海、空各军种用容器的焦耳—汤姆逊冷却装置上。该阀主要特点是它本身独特的密封结构。在其工作温度和系统压力范围内可达到非常低的漏泄。该阀结构坚固,适于战地人员使用。其最大的工作压力为6000磅/英寸~2;被证实的工作温度范围为-32℃～+55℃;能经得起25g,6ms 冲击,在标准温度和压力下,最大漏泄量为0.21厘米~3/时。
BAJ Vickers, UK, has designed a control valve for a pure air Joule-Thomson cryogenic cooling unit. Use it as part of a high pressure gas storage device to provide a method for military personnel to quickly load and unload gas storage containers and thermal reaction devices. This valve can be directly inserted into the pressure source. The valve is ideally suited for military standards and can be used on all Joule-Thomson cooling units for all types of military, marine, naval vessels. The main feature of the valve is its own unique sealing structure. Very low leakage can be achieved over its operating temperature and system pressure. The valve is robust and suitable for use by field personnel. Its maximum operating pressure is 6000 psi. The proven operating temperature range is -32 ° C to + 55 ° C. It is capable of withstanding 25g shocks up to 6ms and has a maximum leakage of 0.21 cm at standard temperature and pressure ~ 3 / hour.
