Problems solved by technology

[0005] The technical problem to be solved by the present invention is: in order to solve the problems existing in the above-mentioned background technology, provide an improved fire-proof tuyere with temperature-adjusting and active fire-fighting functions, and solve the problem that most of the current positive-pressure air-supply vents are simple in structure, only by simply adjusting the blades To control the temperature and the spread of fire from the angle of the fire, but it can't cool down and eliminate the fire, which leads to the problem that the way to prevent the spread is very single and limited, and the functionality is relatively limited

Embodiment 2

[0046] Embodiment 2: It is also possible to change the hand-operated external rotary control valve into an electronic steering valve regulated by a temperature control switch according to the needs, and use the daily external power supply and the backup power supply together, and it can be started by using the backup power supply in special cases. At the same time, a solenoid valve controlled by a temperature control switch can also be installed at the connection end with the indoor fire water pipe 2, which can be automatically closed after the temperature drops and the fire is extinguished, so as to avoid waste of water resources.

Embodiment 3

[0047] Embodiment 3: The hand-operated external rotary control valve can be changed to a hydraulic steering valve controlled by the temperature control switch, and the external pipeline is connected to the indoor fire water pipe 2, and a three-way valve is installed at the connection end of the indoor fire water pipe 2 , and then use water pressure to control the turning of the internal turning blade 8. The working principle is that when encountering high temperature, the temperature control switch controls the three-way valve to supply liquid to the hydraulic steering valve, and controls the turning of the inner turning blade 8. When the pressure continues to increase, it indicates The inner turning blade 8 turns over to the maximum angle, and at this time, the control three-way valve starts to supply liquid to the inside of the outer heat pipe 24 .

Abstract

The invention relates to the technical field of fireproof air ports, in particular to a fireproof air port with temperature adjusting and active fire fighting functions, which comprises an air port outer frame used for being connected with an indoor ventilation pipeline and an indoor fire fighting water pipe internally provided with high-pressure fire fighting water. According to the fireproof tuyere with the temperature adjusting and active fire fighting functions, the interior of the tuyere opening outer frame is divided into the external control cavity, the first internal adjusting cavity, the second internal adjusting cavity and the internal control cavity through the internal partition plates, and the multi-cavity design is adopted, so that the safety of the control end can be effectively improved; smoke overflow at the control end is avoided, heat insulation can be carried out, and the durability of equipment at the control end is improved; the temperature adjusting and fire extinguishing mechanism matched with the indoor fire fighting water pipe is fixedly connected to the internal overturning blade, a heat dissipation flow channel which is connected in series can be formed when the internal overturning blade is overturned and closed, the temperature on the internal overturning blade can be rapidly discharged, and therefore the temperature of the air opening is reduced at the initial stage of a fire.

Description

technical field [0001] The invention relates to the technical field of fire prevention tuyere, in particular to a fire prevention tuyere with the functions of temperature regulation and active fire protection. Background technique [0002] A tuyere is a type of air distributor. In air conditioning engineering, various types of air supply outlets and air return outlets are generally referred to as air distributors. Common air outlets include: single-layer louver air outlet, double-layer louver air outlet, side wall grille air outlet, slit grille air outlet and positive pressure air supply outlet, etc. Among them, the positive pressure air supply port is used to pressurize the air supply in the event of a fire. The positive pressure air supply port will continuously supply air to the front room to maintain the positive pressure in the front room and ensure that the smoke will not spread in this area. Gives people room to escape. [0003] When the temperature is higher than ...
