The invention discloses an automatic drainage structure of an air cylinder, which relates to the technical field of drainage structures, and comprises a venturi connector and a drainage valve, the venturi connector is a three-way joint, extension pipes at the large end and the small end of a taper hole of the venturi connector are respectively communicated with an exhaust pipe of the air cylinder in parallel, and a vertical opening is communicated with one end of the drainage valve through a pipeline. The drainage valve is communicated with the bottom of the air cylinder, a valve element and a drainage hole are arranged in the drainage valve in a sliding mode, air pressure changes in the venturi connector can enable the valve element to slide, and sliding of the valve element can enable the drainage hole to be opened and closed. The working principle of a venturi connector and a venturi tube is utilized, a power source generated by gas flow is adopted to drive the water drain valve to start the water drain function, automatic water drain of the air cylinder is achieved while pneumatic brake operation is conducted, and the problems that manual water drain is needed and operation is difficult at the present stage are solved.

    本发明公开了一种储气筒自动放水结构,涉及放水结构的技术领域,包括文氏连接头和排水阀,文氏连接头为一三通接头,文氏连接头的锥孔大端和小端的延伸管分别与储气筒的排气管并联连通、垂直口通过管路与排水阀的一端连通,排水阀与储气筒的底部连通,排水阀内滑动设置有阀芯和排水孔,文氏连接头内的气压变化能够使阀芯滑动,阀芯的滑动能够使排水孔启闭。本发明利用文氏连接头文丘里管工作原理,采用气体流动产生的动力源从而驱动放水阀开启放水功能,进而在气动刹车操作的同时实现储气筒的自动放水,解决了现阶段需要人工放水的难题和操作困难的问题。
