The design of Haifeng fire shutter generally adopts the characteristics of flat and beautiful drum interior, novel shape, strong rigidity and reasonable and compact structure. Fire shutter is a kind of fire-proof and heat insulation device which is suitable for large openings in buildings. It can effectively prevent the spread of fire and protect the safety of life and property. It is an indispensable fire prevention facility in modern architecture.Fire shutter not only has the function of ordinary door, but also has some special functions, such as fire prevention, smoke isolation, suppression of fire spread, protection of personnel evacuation and so on. It is widely used in high-rise buildings, large shopping malls and other crowded places.Fire shutter is mainly used in large supermarkets, large shopping malls, large professional material markets, large exhibition halls, workshops, warehouses and other public places with fire protection requirements. If there is no firewall between the two fire areas, in addition to the firewall, fire shutter should also be set. It is generally located in the following parts.1) The corridor and the lobby will be closed with the elevator.2) Inspection doors for vertical tube wells such as cable well, tube well, smoke exhaust pipe, garbage passage, etc.3) Divide the fire compartment, control the area of building partition, and set fire wall and door on the wall of fire compartment. When it is difficult to install firewall or fire door in the building, fire shutter should be used instead and water curtain should be used for protection.4) Code (such as code for fire protection design of high rise civil buildings GB 50045-95) or partition doors with special requirements for fire prevention and smoke prevention.When there is a fire, under the control of the central fire control system, the fire shutter will be automatically lowered according to the preset program, so as to prevent the fire from spreading to other areas, and strive for precious time to extinguish the fire.Generally speaking, large buildings are equipped with central fire control system according to the national fire regulations. When there is a fire, the smoke sensor installed on the roof (referred to as "smoke detector") first receives the smoke signal and alarms to the central control system at the same time. After identification, the central fire control system is connected to the power supply of the fire board in the fire area, so that the fire board in the fire area drops at a certain speed. When the rolling shutter is lowered to about 1.5 meters above the ground, it will stop descending to facilitate personnel evacuation. After staying in the middle for a period of time, the fire shutter continues to drop until it is closed. The downstream speed and the median residence time of the fire shutter can be adjusted during installation.Steel fire shutter is an important fire prevention facility for fire compartment and partition in public places. For fire-fighting products with comprehensive mechanical and electrical performance, the installed fire-proof rolling shutter should always be in normal state. In the process of using steel fire shutter, special personnel should use and keep special equipment, and have certain electrical and mechanical basic knowledge.In the process of operation and use, operators shall not leave the workplace without authorization, and shall pay close attention to the opening and closing conditions and execution conditions. No one shall stand or walk under the rolling shutter door when it is opened or closed. In order to prevent travel switch failure, roller shutter stuck, motor blockage and other accidents. Steel fire shutter for fire compartment and partition is not commonly used. In case of fire in this area, rolling shutters should be used effectively. Automatic control fire shutter with linkage control and central control must be centrally controlled according to a set of control instruction program.
