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(dāng)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(dāng)消防停止用水時壓力減少，閥門自動恢復(fù)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 |
