用于干粉灭火器灌装充气装置的灌装头
本技术涉及干粉灭火器灌装
,尤其是涉及一种用于干粉灭火器灌装充气装置的灌装头。
技术介绍
灭火器通常在负压抽真空条件下进行干粉灌装。如图1所示,现有真空灌装头包括盖合在灭火器瓶口周围并与瓶体密封连接的真空抽气腔1',设置在真空抽气腔1'顶部的灌粉通道包括外部壳体2'和内部软管3',软管3'两端与壳体2'密封相连,软管3'外壁和壳体2'内壁形成充气腔室4'。灌粉时,通过与真空抽气腔1'相连的负压装置对瓶体内进行抽真空操作,然后干粉通过软管3'向瓶体内灌注,一段时间后,向充气腔室4'充压,软管3'闭合(如图2所示),结束灌粉。由于软管3'变形频繁,非常容易损坏,检修及更换成本较高;其次,灌粉操作不能即时停止,灌装精度不高,超标后需要返工,工作量较大;再次,瓶口边沿处容易出现积粉,不仅浪费,而且影响后续操作,当粉料洒落在现场时,还容易造成环境污染;最后,由于灌装后负压不能快速解除,灌装头不易与瓶体脱离,延长了操作时间。
