空气呼吸器气瓶充装安全保护装置
摘要：
一种空气呼吸器气瓶充装安全保护装置，包括充装软管、充装阀门、气瓶连通管、空气呼吸器气瓶、锁盖、锁栓、筒体，气瓶连通管与空气呼吸器气瓶连接，气瓶连通管外端安装充装阀门，充装软管与充装阀门连接，空气呼吸器气瓶放置在筒体内，筒体上部开有出口，气瓶连通管从出口穿出，筒体上端口由顶盖封盖，顶盖由销轴连接在筒体上，筒体可以绕销轴旋转，顶盖被锁栓锁定在筒体上，空气呼吸器气瓶在充装过程中发生爆炸时，钢制筒体可以防止爆炸产生的冲击波不会扩散到筒体外，爆炸产生的碎片也不会飞溅，可以保证操作人员和充气泵的安全。因此，本实用新型能达到设计目的，保证空气呼吸器气瓶爆炸时不会造成重大财产损失和人员伤亡事故。
摘要（英）：

A safety protection device of gas cylinder filling of an air breathing apparatus comprises a filling hose, a filling valve, an air cylinder communicating tube, an air breathing apparatus air cylinder, a locking cover, a locking bolt and a tube body. The air cylinder communicating tube is connected with an air breathing apparatus, the filling valve is mounted at the external end of the air cylinder communicating tube, the filling hose is connected with the filling valve, and the air breathing apparatus air cylinder is placed in the tube body. An outlet is formed in the upper portion of the tube body, the air cylinder communicating tube penetrates out from the outlet, an upper end opening of the tube body is capped by a top cap which is connected to the tube body through a pin roll, the tube body can rotate around the pin roll, and the top cover is locked on the tube body by the locking bolt. When the air breathing apparatus explodes in the filling process, the steel tube body can prevent shock waves generated by explosion from spreading to the outside of the tube body, fragments generated in the explosion can not be spattered, and the safety of operating personnel and the safety of an air filling pump are guaranteed. Thus, the safety protection device of gas cylinder filling of the air breathing apparatus can achieve the purpose of design and guarantee the fact that serious property loss and casualty accidents can not happen.
