聯(lián)系我時(shí)，請(qǐng)告知來(lái)自 環(huán)保在線(xiàn)PPA自動(dòng)排氣閥用于自動(dòng)噴水滅火系統(tǒng)、給排水系統(tǒng)及輸水系統(tǒng)等流體為水的系統(tǒng)中，排出水中的空氣
PPA 自動(dòng)排氣閥用于自動(dòng)噴水滅火系統(tǒng)、給排水系統(tǒng)及輸水系統(tǒng)等流體為水的系統(tǒng)中，排出水中的空氣。
自動(dòng)排氣閥有普通，電控兩種形式。
自動(dòng)排氣閥主要用于濕式系統(tǒng)及給排水系統(tǒng)中．可以把管網(wǎng)加壓過(guò)程中，水流動(dòng)時(shí)由于改變壓力，流速而從水中析出的空氣排盡．從而減少管網(wǎng)中水錘現(xiàn)象。提高系統(tǒng)工作效率。
PPAD 電控自動(dòng)排氣閥通過(guò)電磁閥來(lái)控制，電磁閥打開(kāi)時(shí)排氣，關(guān)閉時(shí)，系統(tǒng)內(nèi)可以充氣，主要用于干式系統(tǒng)和預(yù)作用系統(tǒng)，電磁閥由總控室控制，有火情時(shí)．通過(guò)驅(qū)動(dòng)模塊打開(kāi)電磁閥，加速系統(tǒng)排氣，縮短了管網(wǎng)充水時(shí)間，提高滅火效率。
PPA automatic exhaust valve use for automatic sprinkler systems, water supply and drainage systems and water conveyance systems, and such water fluid systems, exhaust air from water.
Auto exhaust valve have two forms of common and electronic control.
Automatic exhaust valve is mainly used for wet systems and drainage systems. It could exhaust air which separates out from water during the forcing procedure on tube network, caused by the pressure and speed changes by water flow. Thereby reduce the water hammer appearance in the pipe network. Improve the system efficiency.
PPAD electronically controlled automatic exhaust valve is controlled by a solenoid valve, when the solenoid valve opens, the air exhaust, when closed, can be inflated within the system, mainly used for dry systems and pre-action system, the solenoid valve control by the master control room, when a fire, open the solenoid valve through drive module, speed up the exhaust and shorten the time of filling water
of pipe network, improve firefighting efficiency.
