用途及特点 Purpose and features 本蝶阀是在引进国外产品的基础上在性能上经过改进和完善的产品。它能按预定程序实现泵阀联动；开启和关闭远距离自动控制、自动保压不掉锤，蝶板不抖动，流阻小；具有可调快、慢关两个阶段，特别是当突然停电或事故停泵时，永存的重锤势能，将自动按预先调节的快慢关两个阶段关阀，防止水锤危害，保护水泵及管网系统安全。 本阀广泛用于水厂、电厂、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. 采用标准 With a standard 主要技术参数 Main technical parameters 1、阀体 2、蝶板 3、液控系统 4、电控箱 5、摆动油缸 6、重锤 1.
