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, an improved fire-proof tuyere with hydraulic adjustment is provided to solve the problem that most of the current positive-pressure air supply vents have simple structures, and most of them use external motors or manual control. The crank is used for control, the external driving mechanism is complex, and the driving method is single. It is only by adjusting the angle of the blades to control the temperature and fire spread, but it cannot cool down, isolate and eliminate the fire, resulting in a very single and limited way to prevent the fire from spreading. Problems with limited functionality

The invention relates to the technical field of ventilation and fire fighting, in particular to a hydraulic adjusting type fireproof tuyere which comprises a main frame body, an external water conveying pipe, an electric control adjusting valve, a temperature control switch and a fire fighting nozzle. According to the hydraulic adjusting type fireproof tuyere, the lateral overturning sealing plate is movably assembled in the tuyere, the lateral hydraulic supporting rod communicating with an external water conveying pipe is used for controlling the lateral overturning sealing plate to be overturned and closed through the water pressure of a fire fighting pipeline, an external driving unit does not need to be used, cost is lower, and popularization and promotion are facilitated; water in the fire-fighting pipeline is guided into the lateral hydraulic supporting rod through a heat conduction pipe of a snakelike structure, so that the temperature of the surface of the lateral overturning sealing plate can be quickly guided away, and the safety and isolation of the fireproof tuyere are improved; the temperature control switch is fixedly installed on the outer side of the closed limiting plate through the lateral frame, the temperature in the pipeline can be monitored more directly and accurately, the electric control adjusting valve is controlled synchronously, and the control mode is simpler and more convenient.
Description
technical field [0001] The invention relates to the technical field of ventilation and fire protection, in particular to a hydraulically adjustable fireproof tuyere. 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 280°C, there is no possibility of people esc...
