| 中文摘要: |
| 目的 研发一种关阀后液体不滴漏的灌装阀。方法 打破传统设计理念， 将灌装阀设计成复合腔， 即灌装腔和负吸腔， 负吸腔在灌装腔内部。灌装阀关闭瞬间， 负吸腔形成上腔和下腔， 下腔具有负压， 阀口周围残留的液体会自动顺着阀芯和负吸杆中间的毛细孔被吸入负吸下腔。结果 灌装阀关闭后没有残留液体滴漏， 避免了残留液体污染包装桶， 省去了传统的接料盘或复杂的负吸装置。结论带负吸功能的液体灌装阀成功地解决了灌装阀滴漏的难题， 而且结构紧凑、 成本低。 |
| 英文摘要: |
| This work aimed to invent a liquid filling valve that does not drip after closing. Breaking the traditional design concept, the filling valve was designed to be composed of two cavities, the filling cavity and the negative suction cavity, and the negative suction cavity was within the filling cavity. At the moment of closing the filling valve, upper cavity and lower cavity were formed in the negative suction cavity. The lower cavity had a negative pressure, which could automatically suck the residual liquid into the negative suction lower cavity along the valve-core and the slender hole in the middle of the negative suction valve-stem. The filling valve did not drip the liquid after closing, avoiding pollution of the packaging bottles by the residual liquid, and there was no need to install the traditional liquid collecting plate or the complicated negative suction device. Liquid filling valve with negative suction function was successful in solving the problem of filling valve dripping. In addition, the filling valve had compact structure and low manufacturing cost. |
