Description
Technical field
The utility model relates to flue gas exhaust pipeline, particularly a kind ofly prevents the house kitchen of each layer recirculation structure, the sizing pipeline of washroom flue gas exhaust pipeline.
Background technology
In the market, cement hand work flue, cement mechanism flue, composite plate assembled flue generality is a kind of empty flue gas exhaust pipeline, backflow proof is not had to construct, counterflow unit is not had yet, the tobacco tar levels of floor smoke discharging pipe is gone here and there back and forth, causes and pour in down a chimney and alter cigarette and alter the serious potential safety hazard such as taste.
Utility model content
For above-mentioned situation, for overcoming the defect of prior art, the object of the utility model is just to provide a kind of house kitchen, the anti-backflow in washroom, pours in down a chimney, alters the flue gas exhaust pipeline that cigarette alters taste, according to hydromechanical general principle, carry out devising the function of symmetrical variable-pressure plate ZDA guiding device structure, fire-preventing check valve, to make in flue gas exhaust pipeline soot gas through transformation, form jet, function is extricated oneself in drainage.Each floor smoke backflow can be prevented.Solve the retardance of soot gas eddy current, air curtain in pipeline and flue gas to pour in down a chimney and alter cigarette and alter the problems such as taste, meet the demand of dwelling construction engineering.
The technical solution of the utility model is, comprise the flue be arranged on multi-storey building, the front end of every one deck flue all has air inlet, the flue inside wall symmetry of air inlet both sides is equipped with the backflow proof variable-pressure plate of the triangular in shape or arc of vertical cross-section, the convex stupefied limit of backflow proof variable-pressure plate is staggered relatively, the ZDA guiding device be fixed on flue is provided with between two backflow proof variable-pressure plates, on air inlet, fire-preventing check valve is equipped with in sealing, and the outlet flue of fire-preventing check valve is connected to entering on mouth of ZDA guiding device.
The performance of a kind of house kitchen of the present utility model, washroom flue gas exhaust pipeline is, when range hood works, oil smoke enters ZDA guiding device through fire-preventing check valve and flows in main pipeline.Gas in pipeline defines the jet of gas through the transformation of symmetrical variable-pressure plate, the drainage that the gas under the effect of jet in guiding device defines.With hydrodynamics venturi principle Functional Design, pipeline air current of smoke removal can be made to flow into upper strata smoothly.Avoid flue gas retardance curtain and vortex phenomenon.Reach and prevent each layer smoke backflow, pour in down a chimney, alter cigarette, alter taste performance.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
As shown in Figure 1 to Figure 3, the utility model comprises the flue 1 be arranged on multi-storey building, the front end of every one deck flue 1 all has air inlet 2, the flue 1 inside wall symmetry of air inlet 2 both sides is equipped with the backflow proof variable-pressure plate 3 of the triangular in shape or arc of vertical cross-section, the convex stupefied limit of backflow proof variable-pressure plate 3 is staggered relatively, the ZDA guiding device 4 be fixed on flue 1 is provided with between two backflow proof variable-pressure plates 3, on air inlet 2, fire-preventing check valve 5 is equipped with in sealing, and the outlet flue of fire-preventing check valve 5 is connected to entering on mouth of ZDA guiding device 4.
The vertical cross-section of described backflow proof variable-pressure plate 3 is isosceles triangle, and the face at its place, isosceles triangle base is fixed on flue 1.
The flue 1 of described every one deck is built with the transformation stiffener 6 be placed in below ZDA guiding device 4, and described transformation stiffener 6 is vertically fixed on the centre position of flue 1 front and back sides.
Front-rear side walls centre position in flue 1 between described ZDA guiding device 4 and transformation stiffener 6 is fixed with vertical directed variable-pressure plate 7.
Described flue 1 is spliced to form by four vertical glass fibre and magnesium cement boards, described glass fibre and magnesium cement board is towards the one-sided smooth in pipeline, a plucking dorsad in pipeline, the one side of light is flue 1 inwall, avoids greasy the accumulation on wall body of the cigarette ash in flue 1 to affect the unobstructed of air-flow.Special scored surface is used for the outer wall of pipeline, is convenient to the associativity of rendering layer cement mortar.Alkali-resistant glass fibre guipure 8 is used to process the globality that assembled seam reaches pipeline.Solidity is added with galvanized sheet iron 9 cornerite pipeline.
A kind of house kitchen of the present utility model, washroom flue gas exhaust pipeline, arrange symmetrical backflow proof variable-pressure plate 3, air-flow in flue 1 can be made under the effect of backflow proof variable-pressure plate 3 to form gas jet in flue 1.And define gas in air inlet port place ZDA guiding device 4 when gas jet and form drainage and outflow of extricating oneself.Fire-preventing check valve 5 is opened freely in ZDA guiding device 4, not by the impact of other air-flows.Serve the flue gas that upper strata flue gas flows into lower floor's pipeline and pipeline never and can not flow into function in guiding device.
Described backflow proof variable-pressure plate 3 and ZDA guiding device 4, all can manufacture at cement products and the assembled goods of composite plate.
Fire-preventing check valve 5 forms fire-preventing check valve 5 valve opening freely at backflow proof variable-pressure plate 3 under the effect of guiding device, situation in making smooth in exhaust static pressure stable.Vertical variable-pressure plate meets can not form eddy current and inversion of direct current and effect of increasing for isolating two strands of air-flows.As Fig. 2: shown duct length unit is with (㎜) calculate, length that story height equals pipeline deducts 6 ㎜, general length is 2700 ㎜-3200 ㎜; Backflow proof variable-pressure plate is length 600 ㎜; In air inlet port, distance pipeline top is 300 ㎜; ZDA guiding device is length 600 ㎜; Kitchen air inlet diameter 160 ㎜; Washroom air inlet diameter is 120 ㎜.As shown in Figure 3; (1) pipeline wall thickness is 15 ㎜.(2) backflow proof structure transformation camber be lower in upper 9,5,3(㎜).(3) ZDA guiding device opening is 8 ㎜, and wide is 220 ㎜.(4) interior chamfering is 30X30 (㎜).(1) pipeline.(2) temporary fixed 438U type gas steel nail.(3) combinated seam sealing alkali-proof glass guipure 4X60(㎜).(4) strong zinc-plated band iron cornerite 0.6X30X100(㎜).
Described pipeline is by Code for design of dwelling houses GB50096-2011 type design.According to national industry JG/T194-2006 standard.Fire endurance reaches 1.0/H, vertical bearing capacity reaches more than 90KN, and anti-soft impulse 10 ㎏ sandbags, are highly freely fallen by 1m, and same position impacts 5 times and do not ftracture.
