    詳細信息

    一、結(jié)構(gòu)及用途 Structure and purpose

    該閥用于生活供水和消防供水并聯(lián)供水系統(tǒng)中,正常情況供生活用水,當火災(zāi)發(fā)生時消防用水時,閥門自動關(guān)閉生活用水,確保足夠的消防用水。當消防停止用水時壓力減少,閥門自動恢復生活用水,該閥使系統(tǒng)無須另設(shè)專門的消防單獨供水管網(wǎng),大大地節(jié)省了工程建設(shè)成本和日常的用水量。該閥控制靈敏、安全可靠、調(diào)試簡單、使用壽命長。

    Used in the living and fire-fighting merged water supply system It supplies living water at normal condition and.in case of a fire,automatically close the living water and open the fire-fighting one to make it surely enough,and then when fire-fighting water stops and the pressure is reduced,resets the living wa-ter automatically.Thus making the system no need to set an individual fire-fighting water supply pipe network and both engineering construction cost and daily water used quantity greatly saved.It features sensitive control,safety,reliability,simple debugging and long duration
