Abstract
The utility model relates to a coupling type fume-crossing prevention exhausting valve for residence shared exhausting channels. The coupling type fume-crossing prevention exhausting valve is provided with a straight-way type valve box (2), the tail end of the valve box (2) is provided with a gas exhausting coupling interface (3), and a vertical valve plate (4) is fixed in the straight-way type valve box (2). The utility model has the advantages of straight line flow of fume in the valve, small frictional resistance, clear gas exhaust, easy detachment or installation of a valve body, and convenient maintenance and cleaning. Oil on the valve plate and a valve seat can flow out the valve body automatically, and the valve plate can not be stuck on the valve seat, so that the open is easy.
Description
The utility model relates to a kind of anti-smoke blowing air bleeding valve, particularly with the anti-smoke blowing air bleeding valve of the matching used coupling type of coupling type guiding device of the shared exhaust duct of dwelling house.
At present, developed the anti-smoke blowing air bleeding valve (check (non-return) valve) of multiple version, for example: the patent No. is the pressure swing type check (non-return) valve of ZL95243308.7 and the dual check (non-return) valve of damp type that the patent No. is ZL96219620.7, and they have played certain effect for the return air taint of odour problem that solves the shared exhaust duct of dwelling house.But the clack box of these two kinds of check (non-return) valves is structure in a zigzag, and flue gas must be through just entering the guiding device (air guide elbow) of shared exhaust duct in clack box behind two 90 ° of zig zags, and frictional resistance is big, and exhaust is not smooth, influences indoor hygienic conditions; Check (non-return) valve is connected as a whole with air guide bend pipe, be fixed on the shared exhaust duct by screw, when resident family carries out indoor facing, often these fixed screws is covered in the finish coat, makes that check (non-return) valve is difficult to remove, and causes and safeguards and the cleaning difficulty; All use horizontal type valve plate (blinds) in the clack box, the greasy dirt on the valve plate and the contact surface of valve seat is difficult to remove voluntarily, and greasy dirt causes valve plate to be bonded on the valve seat, is difficult to open.
The purpose of this utility model provides the anti-smoke blowing air bleeding valve of coupling type of the shared exhaust duct of a kind of dwelling house, flue gas streamlined flow in the valve, frictional resistance is little, exhaust is smooth and easy, valve body is easy to pull down or load onto, and is convenient to maintenance and cleaning, and the oil on valve plate and the valve seat can flow out valve body voluntarily, valve plate can not be bonded on the valve seat, is easy to open.
Technical solution of the present utility model is that the anti-smoke blowing air bleeding valve of coupling type has a through type clack box, and the clack box end has exhaust coupling interface, and the internal fixation of through type clack box vertical valve plate.
The above through type clack box inlet end has an air inlet cover interface tube.
The cross sectional shape of the utility model air inlet cover interface tube, through type clack box and exhaust coupling interface is circular or square and other polygons.
Above the utility model air inlet cover interface tube and through type clack box and exhaust coupling interface are positioned on same the center line.
The sectional area of the utility model exhaust coupling interface is not less than the sectional area of air inlet cover interface tube.
The internal fixation of above the utility model through type clack box be can only unidirectional unlatching vertical valve plate.
The bottom of the utility model through type clack box is connected with the catchment cup that communicates with it.
The anti-smoke blowing air bleeding valve of the coupling type of the shared exhaust duct of dwelling house of the present utility model adopts the through type clack box, the front end of clack box has air inlet cover interface tube, the end of clack box has exhaust coupling interface, the three is positioned on same the center line, make air-flow streamlined flow in whole valve body, do not have above-mentioned turning phenomenon, frictional resistance is little, and exhaust is freely suitable.The air inlet of clack box front end cover interface tube can be matched with the blast pipe of resident family exhaust equipment; The exhaust coupling interface of clack box end can be matched with the coupling type guiding device of shared exhaust duct.Therefore, the anti-smoke blowing air bleeding valve of coupling type of the present utility model can be installed and dismantle easily, is easy to safeguard and clean.The internal fixation of clack box vertical valve plate, can in time the greasy dirt on the valve plate and the contact surface of valve seat be entered in the catchment cup of clack box bottom voluntarily.
The utility model advantage is the anti-smoke blowing air bleeding valve of coupling type, and flue gas streamlined flow frictional resistance is little in valve, and exhaust is smooth and easy, valve body is easy to pull down or load onto, and is convenient to safeguard and clean the oil on valve plate and the valve seat, also can flow out valve body voluntarily, valve plate can not be bonded on the valve seat, is easy to open.
Below in conjunction with accompanying drawing embodiment of the present utility model is described:
Fig. 1 organigram of the present utility model;
Fig. 2 user mode schematic diagram of the present utility model.
According to illustrated in figures 1 and 2, the anti-smoke blowing air bleeding valve of coupling type of the present utility model is the auxiliary products of the shared exhaust duct of dwelling house, between the blast pipe of guiding device and resident family's exhaust equipment, is fixed on the guiding device by the coupling connected mode.The utility model has a through type clack box 2, and clack box 2 ends have exhaust coupling interface 3, the internal fixation of through type clack box 2 can only unidirectional unlatching vertical valve plate 4.Through type clack box 2 inlet ends have an air inlet cover interface tube 1, and the cross sectional shape of air inlet cover interface tube 1, through type clack box 2 and exhaust coupling interface 3 is that through type clack box 2 is the inequilateral octagon, and air inlet cover interface tube 1 is that circle and exhaust coupling interface are squares.Air inlet cover interface tube 1 is positioned on same the center line with through type clack box 2 and exhaust coupling interface 3.The sectional area of exhaust coupling interface 3 is greater than the sectional area of air inlet socket 1.The bottom of through type clack box 2 is connected with the catchment cup 5 that communicates with it.
Installation method of the present utility model is: by the exhaust coupling interface of valve body end, the anti-smoke blowing air bleeding valve of coupling type of the present utility model is fixed on the coupling type guiding device 7 of shared exhaust duct 6; On the air inlet cover interface tube of valve body front end, connect the blast pipe 8 of resident family's exhaust equipment.When the exhaust equipment (smoke exhaust or exhaust fan) of resident family moves, the blast pipe that air communication is crossed exhaust equipment enters the anti-smoke blowing air bleeding valve of coupling type, after pushing the vertical valve plate in the clack box open, enter guiding device, import shared exhaust duct then through exhaust coupling interface.
