Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, the utility model lampblack-preventing check fire valve is made up of non-return valve gap 1, non-return valve body 2, connection pedestal 3, fire prevention valve gap 4 and fire prevention valve body 5, it is inner that non-return valve gap 1 is connected in non-return valve body 2, non-return valve gap 1 and non-return valve body 2 are made up of flame retardant material or are provided with fire resistant coating, have good fire performance.Non-return valve body 2 adopts hasp, buckle or screw attachment in being connected pedestal 3 both sides with fire prevention valve body 5, connect in the middle of pedestal 3 bottom and be provided with axial oil guide slot, the exhaust outlet of fire prevention valve body 5 is articulated with on the downside of fire prevention valve gap 4, be arranged with the sealing strip bent to the inside outside fire prevention valve gap 4, and be provided with magnetic material and elastic flame seal ring at the exhaust outlet edge of fire prevention valve body 5.The spring-like made by two-way shape memory alloy on the upside of fire prevention valve gap 4 or sheet band shape top draw piece are connected with fire prevention valve body 5.Fire prevention valve body 5 adopts stainless steel or alfer by welding, riveted joint or screw spicing forming type, fire prevention valve gap 4 adopt stainless steel or alfer one time punching molded, be convenient to manufacture and structure and fireproof performance are stablized.
When installing the utility model lampblack-preventing check fire valve, first tapping sample plate perforate on flue, get a wide 22cm, the rectangular of high 23cm, next connects between pedestal 3 reverse side and body of wall stamps silicon sealant, metope is inserted in the extension of pedestal 3 reverse side, make tightness between the two best, be screwed, again non-return valve body 2 is connected with smoke pipe, first be screwed, seal with aluminum foil and adhesive tape afterwards, finally non-return valve body 2 is connected by buckle with pedestal, pin stainless steel hasp lock, connect with screw again and fix fire prevention valve body 4 and be connected pedestal 3, namely installation is completed.When needs clean non-return valve body 2 and non-return valve gap 1, only need open hasp lock, just easily can take out non-return valve body 2 and non-return valve gap 1.
When not breaking out of fire, top draw piece keeps normality in normal temperature, supports fire prevention valve gap 1 and opens.During normal use range hood, the gas that range hood is arranged outward makes the non-return valve gap 1 in the non-return valve body of the utility model lampblack-preventing check fire valve 2 open, and oil smoke is discharged to common duct.When not using range hood, non-return valve gap 1 falls under gravity naturally, completely closed in non-return valve body 2 inside, prevents scurrying into of oil smoke.The oil stain that valve body 5 inwall of preventing fires accumulates effectively can be collected with the radial oil trap that the axial oil guide slot being connected pedestal 3 is connected in fire prevention valve body 5 bottom, prevents it from directly pouring in down a chimney into non-return valve body 2, if desired, fire prevention valve body 5 and non-return valve body 2 can be pulled down cleaning.
In the event of a fire, the spring-like that high temperature makes two-way shape memory alloy make or the top draw piece temperature distortion of sheet band shape, drop-down fire prevention valve gap 4, fire prevention valve gap 4 is fallen after rise, fire prevention valve body 5 exhaust outlet being provided with magnetic material and elastic flame seal ring with edge is fitted closed completely under the effect of pulling force, gravity, magnetic force and vacuum adsorption force, prevents fire spread.After fire, the top draw piece under normal temperature returns to normal, upper top and support fire prevention valve gap 4 open, normal cooking-fume discharging function can be recovered.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, without departing from the concept of the premise utility; can also make some improvements and modifications, these improvements and modifications also should be considered as in the utility model protection domain.
