Description
Technical field
It the utility model is related to kitchen and bath's exhaust duct, the flow-guiding non-return used in specifically a kind of kitchen and bath's exhaust duct
Valve.
Background technology
Cooking fume in kitchen and bath drains into the cooking fume passage of check-valves by range hood or ventilating fan, passes through air draft
Wind-force, open valve block, it is public that the pernicious gas of lampblack absorber or ventilating fan discharge from the air outlet of check-valves drains into residential building
In longitudinal exhaust duct, discharge oil smoke and pernicious gas are concentrated from roof by public longitudinal flue.
The check-valves used in existing kitchen and bath's exhaust duct：When flue gas is discharged by the air outlet of valve body, based on valve block
Closing to air outlet, flue gas outwards jack up valve block and spread first, and because the both sides of valve block are not kept out the wind, flue gas is jacking up valve
Not only diffuse up after piece, can also be spread to the left and right sides of valve block, it is serious, cigarette can be caused back；On the other hand, arranging
When flue gas stream in air flue is excessive, valve block there is also because opening angle is excessive can not automatically reset phenomenon.
Based on this, a kind of flow-guiding non-return valve is designed, does not keep out the wind and is difficult to automatic to solve the left and right sides of existing valve block
The problem of reset.
The content of the invention
Technical assignment of the present utility model is that solve the deficiencies in the prior art, there is provided a kind of flow-guiding non-return valve.
Technical scheme is used by the utility model solves its technical problem：
A kind of flow-guiding non-return valve, its structure include valve body and valve block, and valve inner has a cooking fume passage, and the two of valve body
The relative air inlet port and air outlet for offering connection cooking fume passage in end.The axial cross section of valve body is trapezoidal, air outlet
It is opened in the inclined-plane of valve body；Valve block is articulated and connected with valve body, resetting structure is provided between valve block and valve body, and valve block is having gas
Stream opens air outlet when entering valve body, and valve block enters in airless fashionable closes air outlet by resetting structure；Valve block it is interior
Surface both sides are relatively fixed the fin of guide functions, and fin follows valve block to be synchronously turned on and off to expose to valve body or hidden
It is hidden in valve inner.
On the basis of said structure, involved valve block is plane or globoidal structure.
On the basis of said structure, involved resetting structure is at least one of spring, balance weight, latch plate.
On the basis of said structure, the involved fin mode connects for screw or it is welded to connect in valve block.
On the basis of said structure, involved valve block is when opening air outlet in the presence of air-flow, valve block and valve body
The angle of axis is no more than 120 degree.
On the basis of said structure, there is gap between involved fin and valve body.
Caused beneficial effect is a kind of flow-guiding non-return valve of the present utility model compared with prior art：
The utility model is simple in construction, reasonable in design, and fin is set up by the inner surface both sides in valve block, to flowing out valve body
The air-flow of cooking fume passage carries out water conservancy diversion, makes air-flow up, and avoids air-flow from being spread to valve block both sides；Meanwhile excellent axial direction is selected to cut
The trapezoidal valve body in face, and resetting structure is set between valve block and valve body, to realize the self-return of valve block.
Brief description of the drawings
Accompanying drawing 1 is structural perspective of the present utility model；
Accompanying drawing 2 is the structural front view that the utility model is in opening；
Accompanying drawing 3 is the structural front view that the utility model is closed.
Each label represents in figure：
1st, valve body, 2, valve block, 3, air inlet port, 4, air outlet, 5, fin；
Arrow in accompanying drawing 1 and accompanying drawing 2 represents air flow direction.
Embodiment
Below in conjunction with the accompanying drawings 1,2,3, a kind of flow-guiding non-return valve of the present utility model is described in detail below.
As shown in Figure 1, a kind of flow-guiding non-return valve of the present utility model, its structure include valve body 1 and valve block 2, valve body 1
Inside has cooking fume passage, the relative air inlet port 3 and air outlet 4 for offering connection cooking fume passage in both ends of valve body 1.
The axial cross section of valve body 1 is trapezoidal, and air outlet 4 is opened in the inclined-plane of valve body 1.
Valve block 2 is plane or globoidal structure, and bottom and the valve body 1 of valve block 2 are articulated and connected, the inner surface of valve block 2 and valve body 1 it
Between be provided with resetting structure, and valve block 2 opens air outlet 4 when there is air-flow to enter valve body 1, and valve block 2 enters fashionable in airless
Air outlet 4 is closed by resetting structure.
The inner surface both sides of valve block 2 have been fixed with the fin 5 of guide functions with respect to screw, and fin 5 follows valve block 2 synchronously to open
Open to expose from valve body 1, fin 5 follows the close synchronously of valve block 2 and is hidden in inside valve body 1.
During utility model works, on the basis of accompanying drawing 1, refer to the attached drawing 2,3, arrow represents air flow direction in accompanying drawing 2.
Air-flow enters cooking fume passage by the air inlet port 3 of valve body 1, and valve block 2 opens the air outlet 4 of valve body 1 in the presence of air-flow,
Bottom based on valve block 2 is articulated and connected is relatively fixed fin 5, air-flow exits valve body 1 in valve body 1, the inner surface both sides of valve block 2
Air outlet 4 after, air-flow is up under the water conservancy diversion of valve block 2 and fin 5, directly avoids air-flow and expands to the both sides of valve block 2
Scattered phenomenon.
In actual use, it can be appreciated that resetting structure can be selected in spring, balance weight, latch plate at least
It is a kind of.
It should be noted is that valve block 2 is when opening air outlet 4 in the presence of air-flow, valve block 2 and the axis of valve body 1
Angle be no more than 120 degree.
Also need to explanation is a little to have gap between fin 5 and valve body 1, is following valve block 2 same to reduce fin 5
Friction when step acts between the inwall of valve body 1.Certainly, bent tab 5 is relatively distant from the edge of valve block 2 or increased at the edge
Limit bit architecture, on the basis of resetting structure, further to limit the opening angle of valve block 2, and those skilled in the art
A kind of practicable techniques scheme that can be taken according to being actually needed.
Also need to explanation is a little that for fin 5 when following 2 close synchronously of valve block, fin 5 can also be coated on valve body 1
Outer surface.
Finally it should be noted that above content is only illustrating the technical solution of the utility model, rather than to this practicality
The limitation of novel protected scope, although the specific embodiment part explains to the utility model, this area
It is to be appreciated by one skilled in the art that being modified to the technical solution of the utility model or equivalent substitution, this is not still departed from
The spirit and scope of utility model technical scheme.
