Abstract
The invention discloses a liquid sealed fume extractor check valve. The check valve comprises a valve body, wherein a fume exhaust hole is formed in the center of the valve body; the check valve is characterized in that: the upper part of the valve body at the periphery of the fume exhaust hole is provided with an annular liquid storage tank for filling sealing liquid; a circular valve cover is inserted into the valve body and covers the upper hole of the fume exhaust hole, and the outer wall of the valve cover is inserted into the lower part of the annular liquid storage tank; a guide cylinder is arranged in the valve cover and is inserted into the fume exhaust hole; and the wall of the guide cylinder is uniformly provided with fume exhaust ports. The check valve has the advantages that: liquid sealing can be realized by pouring the sealing liquid into the annular liquid storage tank, so that a basic fume exhaust function can be realized, and the fume exhausted by other residents is prevented from flowing into a fume extractor through a public flue; the check valve has a good sealing effect, does not inflow the fume or return flavor and effectively keeps air quality of an indoor kitchen; and the check valve has a simple structure, is convenient to mount, is maintenance-free in long-term use, has long service life and cannot be easily damaged.
Description
Technical field
The present invention be more particularly directed to a kind of liquid-seal type cigarette machine check valve.
Background technique
The check valve of existing range hood mostly is the mechanical shutter formula, and its structure is to constitute by being hinged on one of cigarette machine outlet port or two turnover panels.Cigarette machine turnover panel when work is blown afloat, and makes oil smoke enter public flue discharge by the gap of turnover panel both sides through discharge flue.This mechanical shutter formula check valve is because machining error, meeting generation closure was not tight after particularly long-term use was stained with greasy dirt, causing anti-flavor to lose efficacy, causing oil smoke that resident family downstairs discharges when using the cigarette machine in public flue enters the kitchen of resident family upstairs, not only to impair one's health but also influence daily life.
Summary of the invention
Technical problem to be solved by this invention provides a kind of good sealing effect, do not go here and there oil smoke, do not return the liquid-seal type cigarette machine check valve of flavor.
The present invention is achieved in that it has a valve body, be provided with smoke vent at the valve body center, its special way is: the outer periphery that is positioned at smoke vent on valve body top is useful on the annular liquid storage tank of dress sealing fluid, on valve body, be fitted with circular valve gap, described valve gap covers that suitable for reading and outer wall is inserted into annular liquid storage tank bottom at smoke vent, be provided with guide cylinder in valve gap, guide cylinder is inserted in the smoke vent, is evenly equipped with smoke exhaust port on the guiding barrel.
Above-mentioned liquid-seal type cigarette machine check valve, outer rim is connected with stop collar in the lower end of guide cylinder, to realize spacing to the valve gap lift.
Above-mentioned liquid-seal type cigarette machine check valve is provided with damping pad in annular liquid storage tank, to reduce vibration, avoid sealing fluid to spill because of vibration.
Above-mentioned liquid-seal type cigarette machine check valve, described smoke vent are that the bottom is that macropore, top are the stepped bore of aperture.
Above-mentioned liquid-seal type cigarette machine check valve, the bottom surface of annular liquid storage tank are that the ladder place of smoke vent is conical, are beneficial to discharge oil smoke.
Above-mentioned liquid-seal type cigarette machine check valve is provided with plinth in valve body lower end, is arranged with the bar shaped mounting hole on plinth.
Above-mentioned liquid-seal type cigarette machine check valve is provided with seal groove in the valve body bottom surface, is provided with Stamping Steel Ribbon in seal groove.
Advantage of the present invention is: can realize liquid seal by pour sealing fluid in annular liquid storage tank, can realize basic cooking-fume discharging function, the oil smoke that can avoid other resident families to discharge again seals in through public flue, good sealing effect, do not go here and there oil smoke, do not return flavor, effectively the air quality in kitchen in the holding chamber prevents to have a negative impact with daily life to resident family is healthy; Simple in structure, easy for installation, use Maintenance free for a long time, long service life, not fragile.
Description of drawings
Fig. 1 is the structural representation of invention;
Fig. 2 is the A-A sectional view of Fig. 1.
Among the figure: valve body 1, smoke vent 101, annular liquid storage tank 102, plinth 103, bar shaped mounting hole 104, valve gap 2, damping pad 3, Stamping Steel Ribbon 4, guide cylinder 5, smoke exhaust port 501, stop collar 6, sealing fluid 7.
Embodiment
As shown in the figure, it is columniform valve body 1 that this liquid-seal type cigarette machine check valve has a main body, is provided with it in valve body 1 lower end to be the plinth 103 of one, is arranged with bar shaped mounting hole 104 on plinth 103, be provided with the rectangular seal groove in valve body 1 bottom surface, in seal groove, be provided with Stamping Steel Ribbon 4.Be provided with smoke vent 101 at valve body 1 center, described smoke vent 101 is that macropore, top are the stepped bore of aperture for the bottom, the outer periphery that is positioned at smoke vent 101 on valve body 1 top is useful on the annular liquid storage tank 102 of dress sealing fluid, the bottom surface of annular liquid storage tank 102 is that the ladder place of smoke vent 101 is conical, is beneficial to discharge oil smoke.In annular liquid storage tank 102, be stained with the damping pad of making by cotton or foam 3,, avoid sealing fluid to spill because of vibration to reduce vibration.On valve body 1, be fitted with circular valve gap 2, described valve gap 2 covers that suitable for reading and outer wall is inserted into bottom in the annular liquid storage tank 102 at smoke vent 101, in valve gap 2, be provided with it and be the guide cylinder 5 of one, guide cylinder 5 is inserted in the smoke vent 101 and runs through valve body 1, on guide cylinder 5 walls, be evenly equipped with rectangle smoke exhaust port 501, to realize guiding to valve gap 2 liftings.Outer rim is connected with stop collar 6 in the lower end of guide cylinder 5, to realize spacing to valve gap 2 lifts.
During installation, with valve body 1 by suitable for reading at range hood of bar shaped mounting hole 104 and screw, inject sealing fluid 7 in annular liquid storage tank 102, sealing fluid 7 can make water or salad oil or glycerine water solution etc., and the discharge flue and valve body 1 sealing that are communicated with public flue are pegged graft.During the work of cigarette machine, wind-force is with valve gap 2 jack-up, and the oil smoke that the cigarette machine absorbs is discharged by the gap between smoke exhaust port 501 and valve gap 2 and the valve body 1.When the cigarette machine quit work, valve gap 2 fell automatically under action of gravity and is inserted in the sealing fluid 7, can effectively stop the oil smoke that is gone out by public flue string by sealing fluid 7.
