Problems solved by technology

However, the existing fire dampers are mainly opened and closed by electric control. In high temperature environment, the circuit of the electric control part is easy to be damaged, which leads to the failure of the fire damper to open and close normally and affects the normal operation of the smoke prevention device.

Embodiment Construction

[0038] A preferred embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0039] refer to figure 1 and figure 2 , is a fire extinguishing system for fire engineering disclosed by the present invention, which includes a heat conducting mounting plate 1 , an automatic sprinkler device 2 and a smoke prevention device 3 . The thermally conductive mounting plate 1 is made of high thermally conductive materials such as metal, and the thermally conductive mounting plate 1 is installed on ceilings and other positions.

[0040] The sprinkler 2 includes a water delivery pipeline 21 and a sprinkler head 22 arranged at the outlet end of the water delivery pipeline 21 . The water delivery pipeline 21 is located above the heat conduction mounting plate 1 , and the water delivery pipeline 21 communicates with the municipal water supply pipeline to obtain water from the municipal water supply pipeline. The shower head 22 includ...

Abstract

The invention relates to a fire extinguishing system and a construction method for fire protection engineering and relates to the technical field of fire protection engineering. The fire extinguishingsystem comprises an automatic water-spray fire extinguishing device and a smoke prevention and exhaust device. The smoke prevention and exhaust device comprises a smoke exhaust pipeline and a fire damper; a smoke passage and a valve are formed in a valve frame of the fire damper; and a driving part for driving the valve to rotate is installed on the valve frame. The driving part comprises a driving rod and a weight-adjusting water tank; a water guide pipe is installed on the weight-adjusting water tank; and an opening and closing valve controlled to be opened and closed by a slid-proof thermal expansion glass body is installed on the water pipe. Water enters the weight-adjusting water tank so that the weight-adjusting water tank slides down to drive the driving rod to rotate; the valve rotates along with the driving rod to close the smoke passage, thus a temperature fuse and a smoke sensor are replaced by the skid-proof thermal expansion glass body, so that the opening and closing ofthe fire damper can be implemented by a mechanical structure instead of an electric control structure, thereby preventing possible failure of an electric control part under a high-temperature condition, and thus the fire extinguishing system provided by the invention has the advantage of mechanically controlling the opening and closing so as to prevent failure of the fire damper.

Description

technical field [0001] The invention relates to the technical field of fire engineering, in particular to a fire extinguishing system for fire engineering and a construction method thereof. Background technique [0002] "Fire" is to eliminate hidden dangers and prevent disasters, and fire engineering is mainly used for fire extinguishing and fire prevention construction of buildings. Existing fire-fighting engineering fire extinguishing system mainly consists of two parts, smoke prevention device and fire extinguishing device, which are mainly installed on heat conduction mounting boards such as ceilings. Among them, the smoke prevention and exhaust devices are composed of air supply and exhaust pipes, pipe wells, fire dampers, door switch equipment, air supply and exhaust fans and other equipment. [0003] The fire damper is a normally closed valve, which is opened by the control center through 24V DC or manually. It will automatically close at 280°C and must be reset manu...
