Abstract:
1. A safety valve of a low-pressure gas pipe installed in a waste gas pipeline to discharge condensate, comprising: a first pipeline connected to a bottom surface of the waste gas pipeline and having a waste gas outlet on an inner wall thereof at one side thereof; a second pipeline extending from the first pipeline to be bent and extending in a direction parallel to the first pipeline; and an opening/closing unit for opening or closing the waste gas outlet, wherein the opening/closing unit includes: an opening/closing member hingedly coupled to the inner wall of the first pipeline at one side of the first pipeline to block the waste gas outlet; a connecting member connected to the opening/closing member; and a float connected to the connecting member to be moved in a direction in which the connecting member opens the waste gas outlet along the first pipeline by a pressure and return to an initial position by a buoyant force of the condensate in the first pipeline.
