本標準規(guī)定了鑄石耐磨閘閥的術語和定義、型號命名方法、材料、要求、試驗方法、檢驗規(guī)則以及標志、包裝、運輸和貯存。本標準適用于公稱壓力不大于PN63、公稱尺寸DN50~DN800、使用介質溫度在-29℃~120℃的鑄石耐磨閘閥(以下簡稱閘閥)。
This European Standard specifies the requirements for cast iron gate valves with flanged ends, socket ends or spigot ends. This European Standard is applicable to cast iron gate valves mainly used for industrial and general-purpose applications. However, they can be used for other applications provided the requirements of the relevant performance standards are met. The range of nominal sizes covered is: DN 40; DN 50; DN 65; DN 80; DN 100; DN 125; DN 150; DN 200; DN 250; DN 300; DN 350; DN 400; DN 450; DN 500; DN 600; DN 700; DN 800; DN 900; DN 1000. The range of pressure designations covered is:- isobaric PN 6; PN 10; PN 16; PN 25; - isomorphic, PS 10 bar to PS 1 bar at room temperature.
