Overview
1、 Product definition: Multi leaf smoke exhaust vents are generally installed in corridors or smoke proof front rooms, and are normally closed. In the event of a fire, the smoke detector will emit a fire alarm signal, and the control center will output a valve opening signal. The valve will quickly open, or it can be manually opened quickly for smoke exhaust
Product Details
1、 Product Definition
Multi leaf smoke exhaust outlets are generally installed in corridors or smoke proof front rooms, and are usually closed. In the event of a fire, the smoke detector will emit a fire alarm signal, which will be sent to the control centerOutput valve opening signal, the valve can be quickly opened, or manually opened for smoke exhaust.
The multi leaf smoke exhaust outlet consists of a smoke exhaust valve and an aluminum alloy air outlet, which is normally closed (embedded in the wall) and has a valve thickness of 270mm.
2、 Model Description
PYK PF - (W+250) xH (horizontal) PYK PF Wx (H+250) (vertical)
W-valve nominal width H-valve nominal height 250 actuator installation space
For example:
PYK-PF - (400+250) x400 represents the signal feedback power with manual opening, electrically controlled solenoid opening, and valve open positionCan.
3、 Product Features
① Low leakage rate and good air tightness performance;
② Strong anti-corrosion performance and long service life;
③ The valve opens and closes flexibly, and the position feedback signal is accurate.
4、 Performance parameters
① Nominal pressure: ≤ 300pa at ambient temperature;
② Applicable medium: air (smoke);
③ Leakage rate: a. At ambient temperature, the static pressure difference before and after the valve blade is 1000 ± 15pa,Leakage rate per unit area ≤ 700m3/(m2);
