摘要：【中文】本申请提供了一种用于飞机通气与增压系统的浮子活门，所述浮子活门包括：浮子；呈弯曲形状的摇臂，所述摇臂具有与所述浮子连接的第一端和与浮子活门阀门组件连接的第二端，自所述第一端向所述第二端延伸形成第一端与第二端垂直的弯曲形状；以及浮子活门阀门组件，所述浮子活门阀门组件包括用于与管路连接的第一壳体和用于与所述摇臂连接的第二壳体，第一壳体与第二壳体可转动的连接，以使设置在第二壳体上的盖板能够可控的实现对管路进行开关操作。本申请的浮子活门运动灵活、性能可靠，活门打开后可满足规定的通气流量，保证油箱通气，活门关闭后，密封性好，泄漏量较少，具有可靠性高，安装、拆卸简单，有寿件维修方便等优点。 【EN】The application provides a float valve for aircraft ventilation and pressurization system, the float valve includes: a float; a curved rocker arm having a first end coupled to the float and a second end coupled to a float valve assembly, the rocker arm extending from the first end to the second end forming a curved shape with the first end perpendicular to the second end; and the float valve assembly comprises a first shell and a second shell, the first shell is used for being connected with the pipeline, the second shell is used for being connected with the rocker arm, and the first shell is rotatably connected with the second shell so that the cover plate arranged on the second shell can be controlled to realize the on-off operation of the pipeline. The float valve has the advantages of flexible movement, reliable performance, capability of meeting the specified ventilation flow after the valve is opened, capability of ensuring the ventilation of the oil tank, good sealing property after the valve is closed, less leakage, high reliability, simplicity in installation and disassembly, convenience in maintenance of a long-life part and the like.

摘要：【中文】本发明涉及锂离子电池技术领域，尤其涉及一种电池循环过程原位观测工装，包括左夹块、右夹块、紧固螺栓以及玻璃上盖；所述左夹块和右夹块的上部用于夹紧电池，玻璃上盖通过树脂与所述电池的上部连接，在左夹块和右夹块的中部设有用于调整电池的调整区域，所述紧固螺栓与所述左夹块和右夹块螺纹连接将二者固定。本发明解决了断面处由于负极没有超出正极，多次充放电后出现的析锂现象。 【EN】The invention relates to the technical field of lithium ion batteries, in particular to an in-situ observation tool for a battery cycle process, which comprises a left clamping block, a right clamping block, a fastening bolt and a glass upper cover, wherein the left clamping block is arranged on the left side of the glass upper cover; the upper portions of the left clamping block and the right clamping block are used for clamping a battery, the upper glass cover is connected with the upper portion of the battery through resin, an adjusting area for adjusting the battery is arranged in the middle of the left clamping block and the right clamping block, and the fastening bolt is in threaded connection with the left clamping block and the right clamping block to fix the left clamping block and the right clamping block. The invention solves the problem that the lithium is separated after charging and discharging for many times because the negative electrode does not exceed the positive electrode at the section.
