結(jié)構(gòu)及用途 Structure and purpose
該閥是以電磁閥為導(dǎo)閥的水力操作閥門，用于管路系統(tǒng)中的自動(dòng)控制，根據(jù)電信號(hào)遙控開啟和關(guān)閉管路系統(tǒng)，實(shí)現(xiàn)遠(yuǎn)程操作控制反應(yīng)準(zhǔn)確快速，閥門關(guān)閉速度可調(diào)，關(guān)閉平穩(wěn)而不產(chǎn)生壓力波動(dòng)，電磁閥可采用交流電220V或直流電24V并可根據(jù)場合選用常開或常閉型。該閥體積小、重量輕、維修簡單、使用方便、安全可靠、使用壽命長？纱骈l閥和蝶閥用于大型電動(dòng)操作系統(tǒng)。
A hydraulic operated valve taking a solenoid valve as the pilot valve．used in a pipeline system for automatic control and to remotely control open-close of the system upon an electric signal，accurate and quick response in the execution of remote operation and control，adjustable valve close speed，stably closed without any pressure fluctuation．The solenoid valve can use either AC220V or DC24V power and is available with normal open or close type．This valve features a small volume，light weight，easy repair and use，safety and reliability，long duration and can replace both gate and butterfly valves for use in a large electric operation system.
