Description

一种用于低温生物罐的充装设备及使用方法
技术领域
本发明涉及低温液体充装领域,特别适用于高压液体储罐对低温生物罐的充装。
背景技术
低温生物罐通常是一种常压容器,用于存储低温液体(如:液氮)。在生产过程中主要利用是低温生物罐储存介质中所产生的超低温环境,能够对于食品、生物细胞等的冷冻存储。低温生物罐在食品、生物医学领、科研、美容等多行业领域中广泛应用。
鉴于低温生物罐通常是常压容器,在对低温生物罐充装时,需要尽可能降低充装源的压力(接近于大气压),这样可以避免低温液体喷溅,以免造成对人体伤害。因此当储罐压力较高时,就需要将储罐压力进行泄放,泄压过程中会产生大量噪音及排放大量气体。一旦生产工艺要求充装源的压力必须保持较高压力时,此时为了避免低温液体喷溅只能通过阀门节流的方式进行充装低温生物罐,这种情况下充装效率又特别低下。
故市场需要一种能使高压液源直接对低温生物罐进行充装且价格低廉、安装便捷、安全可靠的充装设备。
