Apparatus for drain vent and water filling for wet type sprinkler systems and Method for drain vent and water filling of wet type sprinkler systems

摘要

The present invention can prevent the air from remaining or being formed in the water supply pipe and the branch pipe by sequentially applying the drainage process, the exhaust process, and the filling process to the water pipe and the branch pipe, which are fire extinguishing pipes, so that the high dissolved oxygen concentration and the local dissolved Drainage, exhaust and impregnation apparatuses for wet sprinklers capable of preventing corrosion of metal pipes that can suppress corrosion of water pipes and branch pipes due to differences in oxygen concentration, and a method of drainage, exhaustion, and apposition of wet sprinkler apparatuses using the same A drain pipe, an exhaust pipe, and an apposition device for a wet sprinkler according to the present invention are provided with a common pipe selectively detachable from a water pipe of a secondary side of a wet type sprinkler device into which digestion water is introduced; A high-pressure gas supply device for injecting high-pressure gas into the secondary-side water supply pipe through the common pipe, thereby forcibly draining the secondary water supply pipe and the remaining water in the branch pipe; A vacuum evacuating device for discharging and discharging water and water for fire extinguishing that remain in the secondary water supply pipe and the branch pipe of the wet sprinkler device through the common pipe; And an apparati to supply water to the secondary water supply pipe and the branch pipe through the common pipe.
