1、簡(jiǎn)易防火閥問(wèn)題：狀態(tài)

1, simple fire valve problem: Status

簡(jiǎn)易防火閥平時(shí)處于開啟狀態(tài)，70攝氏度時(shí)溫度熔斷器觸發(fā)，閥門關(guān)閉；當(dāng)然也可以手動(dòng)關(guān)閉；手動(dòng)復(fù)位。

Simple fire valve is usually in the open state, 70 degrees Celsius, temperature fuse trigger, valve closed; of course, can also be manually closed; manual reset.

2、防火閥問(wèn)題：狀態(tài)

2. Fire valve problem: Status

防火閥：平時(shí)開啟，70°C時(shí)溫度熔斷器動(dòng)作，閥門關(guān)閉；也可手動(dòng)關(guān)閉，手動(dòng)復(fù)位。閥門關(guān)閉后可發(fā)出電信號(hào)消防控制中心。防火閥與普通百葉風(fēng)口組合，可構(gòu)成防火風(fēng)口。

Fire valve: usually open, 70 degrees C, temperature fuse action, valve closed; also can be manually closed, manual reset. After the valve is closed, electrical signals can be sent to the fire control center. The fireproof valve is combined with the common blind air inlet to form a fireproof tuyere.

3.防煙防火閥：平時(shí)開啟，70°C時(shí)溫度熔斷器動(dòng)作，閥門關(guān)閉；也可手動(dòng)關(guān)閉，手動(dòng)復(fù)位消防控制中心可根據(jù)煙感探頭發(fā)出的火警信號(hào)通過(guò)(DC24V)執(zhí)行機(jī)構(gòu)將閥門關(guān)閉；閥門關(guān)閉后可發(fā)出反饋電訊號(hào)消防中心。

3. smoke dampers: normally open, 70 ~ C temperature fuse action, the valve is closed; it can be manually closed, manual reset fire control center according to the smoke alarm signal from the probe through (DC24V) actuator to close the valve after the valve is closed; a feedback signal to the fire control center.

4.排煙閥：平時(shí)常閉，發(fā)生火災(zāi)時(shí)，煙感煙感探頭發(fā)出火警信號(hào)，控制中心通過(guò)(DC24V)執(zhí)行機(jī)構(gòu)將閥門打開排煙，也可手動(dòng)使閥門打開，手動(dòng)復(fù)位。閥門開啟后可發(fā)出電訊號(hào)消防控制中心。還可與其它設(shè)備聯(lián)動(dòng)。排煙閥與普通百葉風(fēng)口或板式風(fēng)口組合，可構(gòu)成排煙風(fēng)口。

4. smoke exhaust valve: usually closed, when a fire, smoke sense smoke detector hair fire signal, control center (DC24V) through the implementation of the valve to open the smoke, or manually open the valve, manual reset. When the valve is opened, signal may be sent to the fire control center. It can also be linked with other devices. The smoke exhaust valve is combined with an ordinary blind air outlet or a plate type air outlet to form a smoke exhaust air outlet.

5.排煙防火閥：平時(shí)常閉，發(fā)生火災(zāi)時(shí)，煙感煙感探頭發(fā)出火警信號(hào)，控制中心通過(guò)(DC24V)執(zhí)行機(jī)構(gòu)將閥門打開排煙，也可手動(dòng)使閥門打開，手動(dòng)復(fù)位。閥門開啟后可發(fā)出電訊號(hào)消防控制中心。還可與其它設(shè)備聯(lián)動(dòng)。當(dāng)煙道內(nèi)溫度達(dá)到280°C時(shí)，溫度熔斷器動(dòng)作，閥門自動(dòng)關(guān)閉。閥門開啟后可發(fā)出電訊號(hào)消防控制中心。

5. smoke fire valve: usually closed, when a fire, smoke sense smoke detector hair fire signal, control center (DC24V) through the implementation of the valve to open the smoke, but also manually open the valve, manual reset. When the valve is opened, signal may be sent to the fire control center. It can also be linked with other devices. When the temperature in the flue reaches 280 degrees C, the temperature fuse action, the valve automatically closed. When the valve is opened, signal may be sent to the fire control center.
