用途及特點 Purpose and features 本蝶閥是在引進國外產品的基礎上在性能上經過改進和完善的產品。它能按預定程序實現泵閥聯動；開啟和關閉遠距離自動控制、自動保壓不掉錘，蝶板不抖動，流阻小；具有可調快、慢關兩個階段，特別是當突然停電或事故停泵時，永存的重錘勢能，將自動按預先調節的快慢關兩個階段關閥，防止水錘危害，保護水泵及管網系統安全。 本閥廣泛用于水廠、電廠、冶金、排灌等大中型工程管道泵站。 The butterfly valve is a product that has been improved and perfected on the basis of introducing foreign products.It can realize pump valve linkage according to the scheduled procedure;Open and close the remote automatic control, automatic protection pressure not drop hammer, butterfly plate not shake, flow resistance small;With adjustable fast and slow close two phases, especially when the pump is stopped when the sudden power failure or accident, eternal heavy hammer, the potential energy will automatically according to the regulation in advance how close two stages close valve, to prevent water hammer damage, protect the pumps and pipe network system security. This valve is widely used in water plant, power plant, metallurgy, drainage and other large and medium-sized engineering pipeline pump station. 采用標準 With a standard 主要技術參數 Main technical parameters 1、閥體 2、蝶板 3、液控系統 4、電控箱 5、擺動油缸 6、重錘 1.
