Abstract
The utility model discloses a sealing valve for a fume exhauster, which comprises a housing, wherein the upper end of the housing is provided with a fume exhaust port, the bottom of the housing is provided with a circular hole on which a sealing pressure cover is arranged, and the middle part in the housing is provided with a cross beam, the middle part of which is provided with a positioning block. An upright post is arranged between the sealing pressure cover and the positioning block of the cross beam. When the fume exhauster works, the exhausted air current vertically blows the pressure cover to rise, and makes the pressure cover suspended above the circular hole. Because the air current is blocked when rising upwards, naturally the air current is exhausted from a gap between the pressure cover and a housing of an exhaust valve. When the fume exhauster does not work, the pressure cover naturally falls vertically on the circular hole, and the sealing pressure cover can effectively achieve the sealing effect and thoroughly prevent the external fume from intruding. The external fume force is bigger, the pressure applied on the pressure cover is bigger, the integrating degree between the pressure cover and an air inlet is better, and the sealing effect is better.
Description
Technical field
The utility model relates to a kind of kitchen flue seal arrangement, is specifically related to a kind of lampblack exhauster seal valve.
Background technique
Existing family, lampblack exhauster outlet valve for kitchen use adopt the folding paper sealing technique, and imprecision during hard plastic sheet folding sealing leaves big space.In case flue returns cigarette, oil smoke will pour indoor along the space, causes said at ordinary times " scurrying flavor " phenomenon, and the harm health of human body.
The model utility content
The purpose of this utility model is to provide a kind of simple in structure, lampblack exhauster seal valve that sealing effect is good.
Technical solutions of the utility model are: the utility model lampblack exhauster seal valve comprises housing, column, sealing gland and a crossbeam, the housing upper end is provided with smoke exhaust port, have a circular hole at the bottom of the shell, activity is provided with a sealing gland on the circular hole, the middle part is provided with crossbeam in the housing, the crossbeam middle part is provided with the guide-localization piece, a column bottom and gland Joint, and the upper end is movably arranged in the guide-localization piece hole.
The utility model lampblack exhauster seal valve, when lampblack exhauster was worked, institute's blast air vertically blew afloat gland, and gland is suspended on the circular hole, because air-flow upwards is obstructed, nature can be discharged from the space between gland and the outlet valve shell.When lampblack exhauster was not worked, gland hung on circular hole naturally, and column can guarantee that gland accurately falls on the circular hole, and sealing gland can reach the effect of sealing effectively, had prevented that up hill and dale external oil smoke from invading.External flue gas strength is big more, and the pressure that puts on the gland is big more, and the combination degree between gland and the suction port is good more, and sealing effect is good more.

Fig. 2 is the sectional view of the utility model Fig. 1 along the A-A direction.
Embodiment
The utility model lampblack exhauster seal valve comprises a housing 1, column 6, sealing gland 3 and crossbeam 4, the housing upper end is provided with smoke exhaust port 7 and is connected with flue by flexible pipe, have a circular hole 2 at the bottom of the shell, activity is provided with a sealing gland 3 on the circular hole, the middle part is provided with crossbeam 4 in the housing, the crossbeam middle part is provided with guide-localization piece 5, column 6 bottoms and sealing gland Joint, and the upper end is movably arranged in the guide-localization piece hole.
During use, earlier column is connected with gland, again column is inserted circular hole.Like this, when lampblack exhauster was worked, gland was blown afloat, because top is withstood by crossbeam, so gland can only be raised to certain altitude, neither can blow away, can not rise so high the air outlet of blocking outlet valve top again, and guarantee that the space between gland and outlet valve shell is utilized effectively.In addition, in order to guarantee the obturation effect between gland and the circular hole, the skin of gland is intended with latex class material, and this class material has softness, and the characteristics that affinity is good can seal effectively.
