Leafy pressure delivery outlet, air conditioning and ventilation FIG Lu Sheng, normally closed pressure delivery outlet

Purpose: outlet types: exhaust port Material: Aluminum Custom processing: Form: double purpose: outlet types: exhaust port Material: Aluminum Custom processing: Form: leafy double outlet: mounted on the side wall, usually was normally closed, when the fire broke out, the fire control center sends an electrical signal, the valve blade open, air. More for the elevator room, staircase, also called a front chamber outlet pressure. Multi-leaf smoke vents: mounted on the side wall, usually was normally closed, when the fire broke out, the fire control center when an electrical signal, the valve blade open beginning smoke, mostly installed in a corridor, product selection points 1. pressure outlet chosen as the primary control parameter specifications. 2. The selection of outlet pressure should pay attention to its features, such as automatic open and close, open and close manually, manual reset, signal output, remote control and other requirements. Second, the construction, installation points 1. Install the operating mechanism must be checked before the air is intact, the action is flexible and effective. Third, the implementation of the standard product standards JG / T14-1999 "ventilation and air conditioning vents" JG / T20-1999 "air distribution performance test methods" engineering standards GB50045-95 "fire protection design of tall buildings" GB50016-2006 "architectural design code for fire protection "GB50243-2002" Ventilation and Air Conditioning Engineering Construction Quality Acceptance "Fourth, the relevant standard atlas K103-1 ~ 3" building smoke control system design and equipment selection and installation of accessory "(bound volumes)
