Abstract
The invention provides an automatic valve deck water-seal smoke check valve, and discloses a device which prevents outdoor oil smoke and cold air from entering a house through an exhaust duct. A lower brim of a solid valve deck and water in a water tank surrounding an air inlet are mainly used as sealing media. At the time of operation, the valve deck is automatically separated from the water surface in the water tank along a hinge and is opened upwards under the action of the wind force of the air inlet, so that the air inlet is communicated with an air outlet, and smoke is discharged normally. When the automatic valve deck water-seal smoke check valve stops operating, the valve deck automatically falls back by self gravity to cover the air inlet, the lower brim of the valve deck is immersed in the water to form a completely airtight sealing structure, external smoke, cold air, mosquitoes and other insects are prevented from entering the automatic valve deck water-seal smoke check valve, and the problem that harmful gas flows backward is completely solved.
Description
Technical field
The present invention relates to a kind ofly prevent outdoor flue gas by the device in the exhaust duct inlet chamber, divide the essential portion of human lives that belongs to according to international CPI.
Background technique
The check valve that known anti-flue gas pours in down a chimney mainly contains two kinds: a kind of is the valve cover formula, connects valve cover and exhaust outlet by hinge, by valve cover make valve cover block exhaust outlet from gravity or magnetic force, electric power, to stop in outside flue gas goes into.Its shortcoming is the check valve with motor, though sealing effect is better than by the check valve from gravity and magnetic force the high waste of cost electric energy, and all solve the problem that influences hinge function and seal point of contact bad sealing behind the oil stain of hanging.Planting in addition is cloth tube soaking type such as the patent No.: 201020522098.4 spirit profit water-stop check valve for flue.This mode is by the cloth tube on the exhaust outlet, and nozzle is immersed in the water to intercept pouring in down a chimney of flue gas, and effect is better than common valve cover formula.But its deficiency is, cloth tube oil stain more easy to hang after the cloth float buoyancy of hanging oil increases, influence the immersion of cloth tube and causes ventilatively under water, and cloth tube itself has certain Air permenbility again, so can not block the pressure that flue gas is poured in down a chimney in the outside fully.Open in addition water tank ingress of air area is excessive, adds that the cloth tube all will bring out a part of water at every turn, causes the evaporation rate of water too fast, must be frequent in the use add water and change the clean cloth tube, so very inconvenient.
Summary of the invention
At problems of the prior art, it is raw materials that the present invention selects high temperature resistant soluble in water and not oily material again such as perfluoroethylene-propylene for use, be sealing medium with solids valve door closure and water, fundamentally solved in the indoor air-changing purging system outside oil smoke cold air mosquito etc. by the problem in the pipeline inlet chamber.Namely solved valve cover formula flue gas check valve in the prior art, influence hinge folding function after hanging oil stain, the problem of seal point of contact bad sealing has overcome cloth tube soaking type check valve oil stain easy to hang, the G﹠W too fast awkward problem of volatilizing thoroughly again.

Embodiment
Valve cover (8) eaves is put into down on the tank (10) of valve body, with hinge (7) valve cover is fixed on interior bottom of gullet.Select the position in air port as required, if select exhaust outlet (1) for use, just sealing cover (9) is installed in side air-out mouth (11), if select the side air-out mouth for use, just sealing cover is installed in exhaust outlet (1).With screw or sealer etc., valve body (2) horizontal fixed on the wall or other local (preferably with the direct integrated design of check valve on the smoke evacuation air regenerating device) easily.After fixing valve body, intake grill, exhaust outlet are connected (pipe diameter does not become head with pipeline simultaneously) respectively with smoke exhaust equipment, outside flue.
According to the sign topped up with water of the transparent water level window of external flume (3) (13), the water of external flume flows into interior tank (10) by the water channel hole (6) of inside and outside bottom of gullet.
Water tank mouth (14) is the position topped up with water up, blocks the mouth of a river with finger again, tank port is turned down is placed on the external flume (3), extracts finger when tank port rapidly out during near the external flume water surface, allows the water seal of tank live tank port.
Valve cover during work (8) breaks away from interior tank (10) water surface automatically along hinge (7) and upwardly opens under the effect of intake grill (4) wind-force, and intake grill is communicated with exhaust outlet, and flue gas is normally discharged.When quitting work, valve cover is by falling back to covering intake grill again automatically from gravity, under the valve cover in the eaves immersion water, intercepts entering of outside flue gas cold air mosquito etc. fully, thoroughly solved the problem of pouring in down a chimney.
Water in tank volatilizees naturally, and when water level was lower than tank port (14), under the effect of barometric pressure principle, water tank (5) replenished from the trend tank at any time, so need not often to add water in using.
Narrow interior tank designs, and only can hold the following eaves of valve cover, reduces the area of contact of water and air as far as possible, has reduced the evaporation rate of water to greatest extent.
The design of valve cover hinge under the seal protection of water, can not influence the flexibility of its function at interior bottom of gullet because of the infringement of oil stain.
The design of two exhaust outlets can be installed in check valve any position between smoke evacuation air regenerating device and the outside flue easily, and does not take the area of external pipe, and windage is little.
Selecting the material of greasy dirt not easy to hang such as perfluoroethylene-propylene and water for use is raw material, not only need not often clean, and valve cover can be as cloth cartridge type check valve when opening, and the cloth tube will adsorb a lot of moisture during unlatching, is blown soon by wind one to vapor away.
Claims (4)
1. one kind falls into the flue gas check valve of tank by valve cover from gravity, constituted by valve cover, valve body, intake grill, two exhaust outlets and water tank, it is characterized in that non-return valve gap covers intake grill, eaves constitutes sealing configuration with the water in the tank around the intake grill again under the valve gap.
2. according to claim 1 described check valve, it is characterized in that there is independently water tank the valve body outside, by the water outlet of water tank bottom, automatically to the external flume water filling, interior tank external flume bottom is communicated with by the water hole according to the barometric pressure principle.
3. according to claim 1 described check valve, it is characterized in that the hinge of valve gap is immersed in interior bottom of gullet.
4. according to the described check valve of claim 1, it is characterized in that respectively there is an exhaust outlet above the check valve and side.
