Overview
1、 The product is defined as a valve installed on the supply and return air ducts of ventilation and air conditioning control systems. It is usually in an open state and closes when the temperature of the smoke in the duct reaches 70 ℃ during a fire. It can meet the requirements of smoke leakage and fire resistance integrity within a certain period of time, and plays a role in smoke isolation and fire resistance
Product Details
1、 Product Definition
Installed on the supply and return air ducts of ventilation and air conditioning systems, it is usually in an open state. In the event of a fire, when the temperature of the smoke inside the ducts reachesA valve that closes at 70 ℃ and can meet the requirements of smoke leakage and fire resistance integrity within a certain period of time, serving as a smoke and fire barrier.The fire damper version consists of components such as valve body, blades, actuator, and temperature sensor.
2、 Model Description
FHF①_②_ Ax BA-valve nominal width B-valve nominal height
① -- Product control method:
W: Temperature sensor controls automatic shutdown
S: Manually control to close
DC: Electric control electromagnet closed
DJ: Electric motor turned off
DQ: Electric control pneumatic mechanism closed
② Product Function Code:
F: Equipped with air volume adjustment function
Y: Equipped with remote reset function
K: Equipped with position signal feedback function after valve opening and closing in place
For example:
FHF-WSDC-K 630x400 indicates automatic closing with temperature sensor (70 ℃), manual closing, electrically controlled solenoid closing, and valveThe signal feedback function after being fully turned off.
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 Good fire resistance integrity.
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 300 ± 15paLeakage per unit area ≤ 500m3/(m2);
b. Within the specified fire resistance time (GB/T15930), the static pressure before and after the valve blade is 300 ± 15pa,Leakage rate per unit area ≤ 700m3/(m2);
