Water supply and drainage system with pneumatic valve inspection and testing

each pneumatic valve products must be inspected before they go out, and some pneumatic valve type testing, to verify whether all of its performance or function to meet the requirements of the standard or use. Second, pneumatic valve manufacturing and inspection test standard of water supply and drainage system of pneumatic valve manufacturing and inspection standard to see the table below. Pneumatic valve manufacturing and inspection standard, standard name related domestic standards GB/T. A, an overview of the pneumatic valve products are used in the pipeline fluid control components, a diversion, river closure, regulate, prevent backflow and shunt effect. Water supply and drainage system with the pneumatic valve and function classification according to the use, there are mainly truncation pneumatic valve class ( Is mainly used for blocking or through medium, such as pneumatic valve gate, globe pneumatic valve, butterfly valve, pneumatic ball valves and cocks pneumatic valve and so on, adjust the pneumatic valve, pneumatic valve check ( Used to prevent backflow of medium, such as a variety of structure check pneumatic valve and exhaust valve class ( Used for automatic discharge air in the pipeline, such as stand-up exhaust pneumatic valve and dual exhaust pneumatic valve etc. Each pneumatic valve products must be inspected before they go out, and some pneumatic valve type testing, to verify whether all of its performance or function to meet the requirements of the standard or use. Second, pneumatic valve manufacturing and inspection test standard of water supply and drainage system of pneumatic valve manufacturing and inspection standard to see the table below. 气动阀门制造和检验标准标准号标准名称国内相关标准GB/T通用气动阀门标志GB/T法兰连接金属气动阀门结构长度GB/T多回转气动阀门驱动装置的连接GB/T通用气动阀门铜合金铸件技术条件GB/T通用气动阀门灰铸铁件技术条件GB/T通用气动阀门球墨铸铁件技术条件GB/T通用气动阀门碳素钢铸件技术条件GB/T通用气动阀门奥氏体钢铸件技术条件GB/T通用气动阀门法兰连接铁制闸气动阀GB/T通用气动阀门铁制截止气动阀与升降式止回气动阀GB/T通用气动阀门法兰和对焊连接钢制闸气动阀GB/T通用气动阀门法兰连接钢制截止气动阀和升降式止回气动阀GB/T通用气动阀门钢制旋启式止回气动阀GB/T通用气动阀门法兰和对焊连接钢制球气动阀GB/T通用气动阀门法兰和对夹连接蝶气动阀GB/T弹簧直接载荷安全气动阀GB/T减压气动阀一般要求GB/T通用气动阀门铁制旋启式止回气动阀GB/T平板钢闸门技术条件GB/T铁制和铜制球气动阀GB/T水暖用内螺纹连接气动阀门JB气动阀门型号编制方法JB/T液控止回蝶气动阀JB/T气动阀门铸钢件外观质量要求JB/T通用气动阀门供货要求JB/T金属密封蝶气动阀JB/T普通型气动阀门电动装置技术条件JB/T气动阀门手动装置技术条件JB/T对夹式刀形闸气动阀GB/T通用气动阀门压力试验JB/T通用气动阀门流量系数和流阻系数的试验方法国外相关标准ISO工业用气动阀门标记ISO铁制闸气动阀ISO主要靠扳手操作的地下用铁制闸气动阀ISO工业用气动阀门— — Pneumatic valve pressure test of ISO general purpose of metal butterfly pneumatic valve BS general-purpose cast iron wedge single or double ram disc brake pneumatic valve BS general-purpose pneumatic parallel slide gate valves BS general-purpose cast iron by pneumatic valve and stop check valve pneumatic valve BS BS general-purpose cast iron check general use of copper alloy by the pneumatic valve, globe check pneumatic pneumatic valve, check valve, gate valve BS general-purpose cast iron and carbon steel butterfly pneumatic valve BS general-purpose cast iron and carbon steel ball pneumatic valve BS general-purpose steel by the pneumatic valve, globe check pneumatic valve, pneumatic valve lift check. http://www pneumatic pneumatic valve manufacturer. /。
