The invention relates to a large-diameter eduction valve and a dejectas collecting system for a train and provided with the eduction valve. The large-diameter eduction valve comprises a valve body, avalve plate and a driving device, wherein the valve body is provided with a vertical through circulation channel used for circulation of a medium, a sliding cavity is formed in the valve body, one endof the valve plate is connected with the driving device, the driving device drives the valve plate to slide to the tail portion in the sliding cavity and completely retract into the sliding cavity inone side of the circulation channel so as to open the circulation channel, or extend forwards out of the front end of the sliding cavity so as to close the circulation channel, and a detachable end cap is mounted at one end of the valve body. By means of the large-diameter eduction valve, the length of the valve plate and the length of the valve body are reduced, the structure of the eduction valve is simplified, the size of the valve body is reduced, and disassembly, assembly and maintenance are facilitated.

    本发明涉及一种大口径排泄阀及安装有该排泄阀的列车用集便系统,包括阀体、阀板和驱动装置,在所述阀体上设置有用于介质流通的上下贯通的流通通道,在所述阀体的内部具有滑动腔,所述阀板的一端与所述驱动装置连接,所述驱动装置带动所述阀板在所述滑动腔内向尾部滑动并全部缩进所述流通通道一侧的滑动腔内以将流通通道打开,或向前伸出至所述滑动腔的前端部以将流通通道断开,在所述阀体的一端安装有可拆卸的端盖。本发明不但减少了阀板和阀体的长度,简化了排泄阀的结构,减少了阀体的体积,而且方便拆装维护。
