铁路罐车用进风抽液装置连体法兰盖结构
摘要：
本发明提出一种铁路罐车用进风抽液装置连体法兰盖结构，进风抽液装置包括进风管、抽液管；进风管、抽液管的上端设置连体法兰；连体法兰盖上设置连通通道封盖，连体法兰盖设置两端分别与进风管和抽液管连接的连通通道，连通通道是底面为斜形面的通道；连通通道封盖与连体法兰盖焊接。本发明铁路罐车用进风抽液装置法兰盖结构，进风与抽液在封盖上加工连通通道，在法兰上面通道加工成“脊”型，有利于介质回流罐体。
摘要（英）：

The invention provides an integral blind flange structure of an air intake and liquid suction device for a railway tank car. The air intake and liquid suction device comprises an air intake pipe and a liquid suction pipe, wherein an integral flange is arranged at the upper ends of the air intake pipe and the liquid suction pipe; a communicating channel sealing cover is arranged on an integral blind flange; the integral blind flange is provided with a communicating channel, of which the two ends are connected with the air intake pipe and the liquid suction pipe respectively; the communicating channel is a channel with an inclined bottom surface; and the communicating channel sealing cover is welded with the integral blind flange. According to the integral blind flange structure of the air intake and liquid suction device for the railway tank car, the communicating channel for air intake and liquid suction is processed in the integral blind flange, and a channel in the upper surface of the integral blind flange is processed in a ridge shape so as to help a medium flow back into a tank body.
