③ when not in use, the fire door 3 is in an open state;
the angle of the fireproof door is adjusted through the adjustable screw 6, and when the angle of the fireproof door is smaller than 90 degrees, the fireproof door 3 is always in an open state and is ventilated for 24 hours;
④ when fire occurs, the fire door 3 is automatically closed;
when a fire breaks out, the fuse link 16 is automatically disconnected (for example, 150 ℃) when meeting high temperature, the buckling and pressing plate bar 13 is pushed by the buckling and pressing plate spring 15 to rotate along the buckling and pressing plate shaft 14, the buckling and pressing plate bar 13 pushes the fireproof door 3 to turn over and buckle on the air outlet 18 of the auxiliary flow guide pipe and the air outlet 19 of the main flow guide pipe, and flame and smoke are prevented from entering;
⑤ closing the fire door manually;
if can not self-closing prevents fire door when taking place the conflagration, perhaps when needing manual closing to prevent fire door, direct manual adjustment adjustable screw 6 promotes through adjustable screw 6 and prevents fire door and force to close.
The invention is designed according to aerodynamic principles. In the embodiment, the air inlet interface 1 (with the diameter of 170 mm) of the main draft tube is connected with a pipeline of the range hood, a jet injection function is generated between the secondary draft tube 20 and the main draft tube 21, the amount of exhaust smoke is more than 1.5 times of that of the prior art, but the electric quantity is not increased. The air inlet interface 2 of the auxiliary guide pipe is connected with an exhaust fan through a hose (capable of bending by 90 degrees), and actively discharges smoke (the lower the main guide pipe is, the higher the auxiliary guide pipe is, the stronger jet injection is, and the larger the smoke discharge amount is). The fireproof door 3 is blown open when the smoke exhaust ventilator is opened, and the smoke exhaust ventilator is closed automatically by self weight after stopping. Prevent that fire door passes through adjustable screw 6 angle regulation, prevents that anti-return chamfer 7 on preventing fire door meets the backward flow, prevents that fire door also can close by oneself. The adjustable screw rod penetrates through the spring 8 and then penetrates through a fire-proof valve shell screw hole 10 of the fire-proof valve shell 9 and then is screwed on. The nut 11 is clamped in the clamping groove 12 to prevent the nut from rotating, when the fuse link 16 is disconnected when the temperature is high at 150 ℃, the buckling plate spring 15 on the buckling plate shaft 14 drives the buckling plate 13 to press the back of the fireproof door, so that the fireproof door is forcibly closed, and flame is prevented from being sprayed out and entering; in case of failure, the fire door can be forced closed.
The invention is characterized in that: the installation is reliable; if a fire disaster happens, the fire door can be directly and forcibly closed manually under the condition that all action elements fail, so that the fire door is simple and convenient; the oil fume can be discharged in 24 hours, so that accidents caused by leakage of liquefied gas can be avoided in a kitchen, and a fire disaster is avoided. If the householder is on fire for other reasons, the auxiliary draft tube can help the auxiliary draft tube to discharge smoke by opening the exhaust fan for other householders on the upper layer and the lower layer. The energy-saving discharge capacity is large; according to the invention, when the range hood is opened and the electricity consumption is the same, the smoke exhaust amount is larger than the smoke exhaust amount of all the smoke exhaust fire valves in the market. Standard requirements kitchen > 300m3H/household, toilet > 80m3The invention can reach the lowest kitchen more than 380m3Per/household, toilet > 160m3The smoke exhaust amount per household is not increased, the auxiliary guide pipe can ventilate for 24 hours, and can be connected with an exhaust fan to forcibly exhaust air, and the smoke exhaust ventilator and the exhaust fan exhaust oil smoke simultaneously.
