SAFETY VALVE FOR A LOW PRESSURE GAS PIPE

摘要

The present description relates to a safety valve for a low pressure gas pipe, which can be installed in a large pipeline along which waste gas generated by a large plant such as steelworks or the like flows, and which can reduce maintenance costs. The safety valve for a low pressure gas pipe of the present description is provided in a waste gas pipeline in order to discharge condensed water, and comprises: a first pipeline which is connected to the bottom surface of the waste gas pipeline, and which in turn has a waste gas pipeline provided on the inner wall of one side thereof; a second pipeline extending from the first pipeline, and which is bent and extends in the direction parallel to that of the first pipeline; and an opening/shutting device for opening or shutting a waste gas outlet port.
