Description

上記目的を達成するため、本発明のガス系消火設備用の消音機能を有する噴射ヘッドは、消火剤ガスを使用するガス系消火設備において消火対象区画に消火剤ガスを放出するために設置される消音手段を備えた噴射ヘッドであって、前記消音手段を、消火剤ガスが供給される配管に螺合して接続された噴射ヘッドの内部にオリフィスを形成するとともに、オリフィスの出口部に消火剤ガスが流通可能な３次元の網目状組織からなる円筒又は円柱形状の金属多孔性の気流の乱れをなくす材料を、前記オリフィスの出口部の反対側の金属多孔性の材料の外面のすべてが面状に大気に露出、開放されてなるように配設して構成したり、該材料を、前記オリフィスの出口部の反対側の金属多孔性の材料の外面が１つの開口部を介して面状に大気に露出、開放されてなるように配設して構成したことを特徴とする。 In order to achieve the above object, a jet head having a sound extinguishing function for a gas fire extinguishing facility according to the present invention is installed to discharge a fire extinguishing agent gas to a fire extinguishing target section in a gas fire extinguishing facility using a fire extinguishing agent gas. An ejection head provided with a silencer, wherein the silencer is screwed into a pipe to which a fire extinguishing agent gas is supplied, and an orifice is formed inside the ejection head, and the extinguishing agent is provided at the outlet of the orifice. A cylindrical or columnar metal porous airflow turbulent material made of a three-dimensional network structure through which gas can flow is used for all the outer surfaces of the metal porous material on the opposite side of the orifice outlet. The material is arranged so that it is exposed to the atmosphere and opened to the atmosphere, or the material has a planar shape with the outer surface of the metal porous material on the opposite side of the outlet portion of the orifice through one opening. Exposed to the atmosphere Characterized by being configured by arranging so been opened.
