D743H,D741X重錘式液控蝶閥

液控蝶閥_執(zhí)行標(biāo)準(zhǔn)：
設(shè)計(jì)按GB12238的規(guī)定
法蘭按GB/T9113、GB/T17241.6的規(guī)定
結(jié)構(gòu)長度按GB12221的規(guī)定
壓力試驗(yàn)按GB/T13927、JB/T9092的規(guī)定

主要性能規(guī)范：

液控蝶閥結(jié)構(gòu)特點(diǎn)：

    1.本閥是新一代液動(dòng)蝶閥，它主要用于介質(zhì)為水的管路系統(tǒng)泵出口，蒹有截止和止回關(guān)閉功能可一閥代兩閥，該閥門止回關(guān)閉時(shí)，能夠?qū)崿F(xiàn)快、慢兩階段關(guān)閉，從而起到消除或減小水錘防止介質(zhì)倒流保護(hù)管路系統(tǒng)的作用。
    2.本閥門采用蓄能器取代了重錘式液動(dòng)碟閥的重錘，用液體的壓力蓄能替代重錘勢(shì)能，從而使該閥門具有設(shè)計(jì)合理、體積小、重量輕、維護(hù)方便等優(yōu)點(diǎn)。
    3.本閥門液壓站和電氣控制箱與閥門下部可整體式安裝也可分體式安裝，閥門不同工況下選擇。
    4.本閥門采用三偏心金屬密封結(jié)構(gòu)，啟閉輕松達(dá)到零泄漏。

液控蝶閥_產(chǎn)品用途：

     本蝶閥適用于介質(zhì)為水的泵出口管路上，用來避免和減少管路系統(tǒng)中介質(zhì)繁榮倒流及產(chǎn)生過大的水錘，以保護(hù)管路系統(tǒng)，其功能事以一閥代兩閥（傳統(tǒng)的管路設(shè)計(jì)中以閘閥配止回閥或以普通蝶閥配止回閥）
