3 Terms and definitions
GB 15930-2007 established and the following terms and definitions apply to this standard.
3.1
Installed in the kitchen exhaust hood or bathroom exhaust fan back to the end of a common fire-rated exhaust pipe inlet, the fan was working
Open state (exhaust emissions), the fan does not work in a natural off state (to prevent the exhaust gas backflow), indoor or shared duct temperature reached regulation
Set value can be automatically shut down, and within a specified time to meet the fire resistance requirements, play the role of smoke valve fire.
3.2
Check valve in the open state, when the temperature sensing element to the state when the valve is closed.
3.3
Check valve in the exhaust fan to stop working, the valve will naturally fall off and closed state.
3.4
Check valve in the non-return state, when the temperature sensing element to the state when the valve is closed. In this state of the valve, without reset, will be
Can not be opened by fan power.
3.5
In the check valve inlet pressure higher than the outlet pressure, the difference between import and export pressure.
