用途及特點(diǎn) Purpose and features 本蝶閥是在引進(jìn)國(guó)外產(chǎn)品的基礎(chǔ)上在性能上經(jīng)過改進(jìn)和完善的產(chǎn)品。它能按預(yù)定程序?qū)崿F(xiàn)泵閥聯(lián)動(dòng)；開啟和關(guān)閉遠(yuǎn)距離自動(dòng)控制、自動(dòng)保壓不掉錘，蝶板不抖動(dòng)，流阻小；具有可調(diào)快、慢關(guān)兩個(gè)階段，特別是當(dāng)突然停電或事故停泵時(shí)，永存的重錘勢(shì)能，將自動(dòng)按預(yù)先調(diào)節(jié)的快慢關(guān)兩個(gè)階段關(guān)閥，防止水錘危害，保護(hù)水泵及管網(wǎng)系統(tǒng)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(biāo)準(zhǔn) With a standard 主要技術(shù)參數(shù) Main technical parameters 1、閥體 2、蝶板 3、液控系統(tǒng) 4、電控箱 5、擺動(dòng)油缸 6、重錘 1.
