Abstract
Disclosed is a safety valve of a low-pressure gas pipe which can be installed in a large-scale pipeline through which waste gases generated in a large-scale factory such as a steel mill flow and can reduce maintenance/management costs. The safety valve of a low-pressure gas pipe installed in a waste gas pipeline to discharge condensate includes: 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.
Claims4
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.
