Abstract
The utility model relates to an automatic fire closing valve used in smoke exhausting duct, aiming at solving the current problem that the fire hazard caused by the lightening of the oil dirt in the exhaust duct which can not be extinguished timely. The utility model is composed of a connecting flange, a valve seat, a valve body, a valve arranged in the valve body and a closing spring and an automatic closing control component arranged on the valve. In case of the fire happened in the exhausting duct, the utility model can be activated to cut off the airflow in the exhausting duct to make the fire extinguish automatically due to lack of fresh air. The utility model has the advantages of easy production, low cost and reliable functions and can be used in new or improved smoke exhausting duct.
Description
Technical field
The utility model relates to a kind of valve of exhaust duct, particularly relates to the automatic isolating valve of a kind of exhaust duct fire.
Background technique
Present a lot of dwelling houses all are provided with the oil smoke exhaust duct, some restaurants especially, and the have dinner kitchen in place of the supply public such as dining room also all is provided with the oil smoke exhaust duct.These oil smoke exhaust ducts are for the environment that purifies the kitchen, the conditions of discharge of optimizing oil smoke gas has played very important effect, but, after using a period of time, the inwall of these oil smoke exhaust ducts will gather a little greases, because grease is the inwall that amasss at airduct, be difficult for being it is found that and out in the cold, tend to because of entering of Mars or high-temperature flue gas these greases that ignite.In case grease is in the exhaust duct internal combustion, and exhaust duct hoists often and discharges, so concerning the grease of burning, exhaust duct plays the wind-drawing effect of chimney, makes grease burn more prosperous and more prosperous, very easily leads to fire.
Summary of the invention
The utility model provides a kind of easy to manufacture, with low cost, reliable, can in time prevent interior fire spreading of the oil smoke exhaust duct that catches fire and then the automatic isolating valve of oil smoke exhaust duct fire that stamps out a fire in order to overcome deficiency of the prior art.
The technological scheme that its technical problem that solves the utility model adopts is that the utility model comprises adpting flange, valve seat, valve body, and valve is housed in valve body, is equipped with on the valve to close spring and close automatic control member.
Described valve is two semicircular galvanized steel plain sheets; The material of described adpting flange is an angle steel; The material of described valve seat is an angle steel; The material of described valve body is a galvanized steel plain sheet; Described to close automatic control member be the nylon rope that is hung between valve and valve body, preferably closes automatic control member and be the nylon rope that is hung between valve and valve body and the assembly parts of low-melting alloy ring.
The beneficial effects of the utility model are: reduce the possibility because of the initiation fire that catches fire in the oil smoke exhaust duct greatly.
Description of drawings
Fig. 1: be cross-sectional view of the present utility model.
Fig. 2: for the A of Fig. 1 to view.
Among the figure: 1. adpting flange, 2. valve seat, 3. valve body, 4. valve is 5. closed spring, 6. closes automatic control member.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
During installation, the utility model is connected with the oil smoke exhaust duct with adpting flange 1, and the diameter of valve body 3 should be identical with the oil smoke exhaust duct, in order to avoid increase the smoke evacuation resistance.At ordinary times, valve 4 is opening state, closes spring 5 pretensions, closes automatic control member 6 and holds valve 4.In case the phenomenon of catching fire in the oil smoke exhaust duct takes place, because close the material of automatic control member 6 is that nylon rope and low-melting alloy ring are formed, so be blown immediately, valve 4 in effect ShiShimonoseki of closing spring 5 to valve seat 2, whole piece oil smoke exhaust duct is the partition state, stoped air-flow, made point of ignition because of there not being the additional of new air from horizontal blanking.Mounting point of the present utility model should be preferable near the oil suction mouth, and effect also can be more remarkable.The utility model is applicable to the oil smoke exhaust duct of new clothes or transformation.
