Abstract

本发明是一种阀门装置，通过流体从阀芯侧进，阀芯头出方式，并以阀芯与阀体的活塞结构实现阀的开关及流体回吸，实现在点胶及喷涂因结构问题而产生的残液(不滴液不拉丝)，以及阀体动力不受流体压力影响可小型型化及快速响应。本发明所需动力可以不受流体压力影响，并有极为显的回吸动作。对实现点胶及喷涂不滴液不拉丝有明显效果。结构简单，易维护，成本低，重要是环保，节能。

Description

低阻力过芯型分段式截止回吸阀
本发明是一种阀门装置，尤其适用于气液体及松散物料等流体的开闭机构。
技术背景：
当前市面上的点胶机所用开关阀头采用正反向关断方式，受流体压力不可小型化，开关响应延迟，并会有残胶溢出。喷涂所用阀也同样会有滴液问题。溢出液体会造成产品、设备及环境污染，并增加人工及处理成本。
发明内容：
为解决在点胶及喷涂因结构问题而产生的残液，以及阀体动力不受流体压力影响。本发明提供一种阀体可以大步改进关关延迟；对出口残液产生大行程回吸而不滴液不拉丝；出液量与时间极度接近正比，且结构简单，易维护清理。
技术方案：
本发明采用通过在阀体内液体从阀芯侧进，阀芯头出方式，并以阀芯与阀体的活塞结构实现阀的开关及出液的大行程回吸。
有益效果：
本发明所用动力可以不受液体压力影响，并有极为显的回吸动作。对涂液或胶液不滴不拉丝。结构简单，易维护，成本低，重要是环保，节能。
附图说明：
附图1为结构示意图
图中1与2均是锁紧螺母组合，3气缸后盖，4密封圈；5气缸阀芯一体杆；6气缸前盖；7气缸阀体倒胶溢出隔块；8阀密封件；9阀体；10阀头；11针孔出液头；12 air A气缸后气口；13air气缸前气口；14 A1倒流胶出口(防胶液进入气缸)；15YA进液口；16YB出液口
具体实施：
当5气缸阀芯一体杆从拉回到底的阀体关闭状态到顶出过程中，10阀头内容积先减少，当5气缸阀芯侧与8阀密封件达到错位时，阀体通路，出液，当5气缸阀芯侧执行回拉动作时，阀芯先关断通路后扩大10阀头内容积，产生回吸果。
