Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings:
Seeing Fig. 1, a kind of lampblack-preventing pours in down a chimney check-valves, including valve seat 1, valve body 2 and non-return valve block 3, institute
State valve body 2 and be provided with valve opening 21, in described non-return valve block 3 is rotatably located at described valve body 2 and for controlling
The folding condition of described valve opening 21, wherein, the most described non-return valve block 3 is by the mode such as rotating shaft or hinge
It is rotatably connected with described valve body 2.When aerofluxus, resident family's oil smoke is through valve opening and can automatically blow described stopping
Return valve block 3 to rotate and realize opening valve opening 21, but when not aerofluxus, described non-return valve block 3 is by gravity
Effect, can rotate reset close valve orifice 21 automatically, and in such flue collector, the oil smoke of other resident families will not seal in.
Wherein, be provided with kuppe 4 at the exhaust opening of described valve body 2 or/and described valve body 2 outer wall be provided with to
The step installed surface 22 being connected with two kinds of various sizes of lampblack absorber exhaustors less, due at described valve body
It is provided with kuppe 4 at the exhaust opening of 2, can quickly the oil smoke that its lampblack absorber is extracted out quickly be got rid of through kuppe 4,
After installing, kuppe 4 steam vent is for upwards to offer simultaneously, the oil smoke therefore downstairs come up in flue collector, no
Can enter in described valve body 2 by kuppe 4, more described non-return valve block 3 will not be closed and affect oil smoke
Efficient eliminating.And during breaking out of fire, it is possible to effectively prevent from pouring in down a chimney entrance.Wherein, outside described valve body 2
Step installed surface 22 on wall, specifically can be correspondingly arranged according to the standard pipe size for lampblack absorber exhaustor, one
As 2-4 step is set can meet existing common model, so by arranging step installed surface 22, can
Meet the lampblack absorber exhaustor different from least two to be connected, make this utility model product more applicable, peace
Dress is convenient, diverse in function, can meet different customer demand.
Further, the flue installed surface of described valve seat 1 is provided with the first sealing frame or the first sealing ring 5.
Owing to described valve seat 1 is arranged on flue collector or flue, there is burr in its contact surface, rough surface, therefore
By the first sealing frame or the first sealing ring 5, can realize sealing and install, leakage cigarette can be reduced and oil smoke overflows.
Further, between described valve body 2 and described non-return valve block 3 and along near described valve opening 21
It is circumferentially with the second sealing frame or/and the second sealing ring 6.Owing to being provided with the second sealing frame or/and the second sealing ring
6, when non-return valve block 3 closure state, it is ensured that non-return valve block 3 and the circumference of valve opening 21 are the most airtight
Lid envelope, therefore can prevent non-return valve block 3 burr that may be present with valve body 2 or deformation thus have influence on
This check-valves sealing effectiveness when normal switching-off so that cooking fume pours in down a chimney to become may not, it is ensured that leakage
Air quantity is zero, really plays the effect of dual elimination smoke blowing taint of odour.Therefore can effectively prevent oil smoke from flowing backwards, can
Solve oil smoke to pour in down a chimney, return the problem such as return of smoke and smell and smoke safe.
As preferably, described second sealing frame is or/and the second sealing ring is installed in described valve body 2 or/and institute
State on non-return valve block 3.Can install described in described valve body 2 and described non-return valve block 3 in arbitrary single side face
Second sealing frame is or/and the second sealing ring；Also can be in described valve body 2 both sides relative with described non-return valve block 3
Described second sealing frame is installed the most simultaneously or/and the second sealing ring on face.
As preferably, described first sealing ring 5 is or/and the second sealing ring 6 uses silica gel sealing ring.
Further, heat fusing or the heat-sensitive sheet 7 of deformation, described check-valves it are provided with in described valve body 2
Being arranged with torsion spring 8 in sheet 3 rotating shaft, this torsion spring 8 is provided with the reset tabletting 9 back to described non-return valve block 3,
This reset tabletting 9 one end card or snap onto on described heat-sensitive sheet 7.When a fire, high temperature causes temperature-sensitive
Sheet 7 fuses or deforms, and after described reset tabletting 9 departs from described heat-sensitive sheet 7 and through lower turn of torsion spring 8 effect
Dynamic resetting, the most described reset tabletting 9 resets non-return valve block 3 described in back pressure and makes it remain off,
Fire hazard aerosol fog can be avoided to pass through valve opening 21 and to enter resident family indoor, play the effect of automatic safe protective.
As preferably, described non-return valve block 3, valve body 2 and valve seat 1 all can use stainless steel material.Cause
This can reduce it and get rusty and cause impact to be installed and sealing effectiveness, in service life, reduces and safeguards and cost of upkeep,
Improve service life of the present utility model.
Preferred embodiment of the present utility model described in detail above.Should be appreciated that the common of this area
Technical staff just can make many modifications and variations according to design of the present utility model without creative work.
Therefore, all technical staff in the art pass through on the basis of existing technology according to design of the present utility model
The available technical scheme of logical analysis, reasoning, or a limited experiment, all should be by claims institute
In the protection domain determined.
