Overview
1、 The product is defined as a valve installed on the pipeline of the mechanical smoke exhaust system, which is usually in an open state. When the temperature of the smoke in the smoke exhaust pipeline reaches 280 ℃ during a fire, it is closed and meets the requirements of smoke leakage and fire resistance integrity for a certain period of time. It plays a role in smoke isolation and fire resistance
Product Details
1、 Product Definition
Installed on the pipeline of the mechanical smoke exhaust system, it is usually in an open state. In case of a fire, when the temperature of the smoke in the smoke exhaust pipeline reaches 280 ℃, it will be closedA valve that is closed and meets the requirements for smoke leakage and fire resistance integrity within a certain period of time, serving as a smoke and fire barrier.The smoke exhaust 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:
PFHF-WSDC-K 500x400 indicates automatic closing with temperature sensor (280 ℃), 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、 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 ± 15pa,Leakage 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);
④ Fire resistance time: ≥ 1.5h (GB/T15930).

Note: Can be made according to customer requirements (cannot exceed 125x800)
Combination valve is a valve combination that has obtained the fire 3C certificate, and the combined valve meets the ventilation area (interface requirements);
The thickness of the combination valve has been increased to 310mm, and a 300mm maintenance space should be reserved around the valve;
When placing an order for a combination valve, the installation method of the valve (pipe installation, wall tile or other) must be informed
