Description

氩气常压置换系统
技术领域
本发明涉及环境舱室的氩气常压置换系统。
背景技术
钛具有密度小、强度高、韧性好、耐腐蚀等优良性能，在航空、船舶等领域具有广泛的应用。钛是一种高活性金属，在高温下会与氧、氮等气体发生反应，在钛合金焊接中广泛存在氧、氮、氢和碳等元素引起的脆化问题，导致焊接零件塑性和韧性下降。因此在钛合金热处理、机加工和焊接等过程中应严格控制有害杂质含量，特别是氢、氧、氮、碳等元素的含量。
为解决上述问题，在实际工程应用中，对于小型的钛合金零件加工，采用局部气体保护或小型真空焊接箱等措施来保证其焊接加工质量。而对于大型复杂的钛合金零件，如船体、潜器大型构件、飞行器大型构件等进行良好的气体保护非常困难。通常将零件置于一个较大密闭舱中，然后对其进行抽真空和充氩气，实现舱内气体的置换，使舱内充满氩气，实现焊接材料与有害杂质气体的隔离。然而，对于有人操作的舱室，受身体条件的限制，无法实现有人工况下的抽真空作业。
发明内容
针对上述问题，为实现气体的有效置换，又不对操作人员身体产生伤害，本发明提出了一种在有人环境下的氩气常压置换系统。
为了解决上述问题，本发明采用如下方案：
一种氩气常压置换系统，包括为作业舱提供气源的氩气供给系统，所述氩气供给系统包括依次相连的液氩储罐、汽化器、调压装置、流量监测装置、加热装置，所述液氩储罐与汽化器之间的连接管道上安装有截止阀，所述汽化器与调压装置之间的连接管道上安装有排气阀，经加热后的氩气通过输出管道与所述作业舱连接，所述输出管道上安装有温度检测装置及进气截止阀；
所述作业舱设置有舱门和观察窗，作业舱的底部设有一与所述输出管道连接的进气口，进气口与出气分布装置连接，氩气通过出气分布装置将氩气均匀的输入至作业舱底部；在作业舱内、出气分布装置上端安装有作业平板，作业平板上设有通气口；作业舱顶部有排气口和排气阀，侧面设置压力检测装置、安全阀和温度检测装置。
作为上述技术方案的进一步改进：
所述出气分布装置为一环形管道结构，管道上布置多个出气口，该出气分布装置可使管道内气体均匀从各出气口排出。
本发明的技术效果在于：
本发明为一种有人环境下的氩气常压置换系统，该系统可有效保证作业舱内氩气浓度符合钛合金材料的焊接要求，同时解决了在有人环境下无法实现气体置换的问题，系统结构简单、可靠。
