Abstract
The utility model relates to a domicile exhaust structure, in particular to an external fireproof valve installation structure of a transformation exhaust device. The exhaust structure comprises a torsional spring (93), a fusible link (91) or a valve (9) controlled by a melting flake hanging pin and a venturi transformation type exhaust assembly (2). The domicile exhaust structure is characterized in that the fireproof valve is connected between an air outlet of the indoor exhaust device and an air inlet (22) of the venturi transformation type exhaust assembly (2) in series, or the valve (9) is arranged in an air inlet (22) which is arranged outside a main exhaust flue (5). The fireproof valve of the exhaust structure is arranged outside the exhaust flue, and once the fusible link is burnt out, the fusible link can be replaced very conveniently.
Description
Technical field
The utility model relates to the dwelling house exhaust structure, and floor gap is by the fire resisting damper device of exhaust duct propagation of flame about especially a kind of the preventing.
Background technology
Kitchen, the toilet of present all kinds of floor houses all have the shared main exhaust flue that the both sides inwall is installed Venturi relatively, each layer resident family enters indoor cigarette, gas flue collector, concentrates from the exit on roof and discharge by the air inlet on the flue collector, can prevent floor gap by the mutual gas blowby of shared flue collector, scurry cigarette.Because the wind pipe and the main exhaust flue of range hood device accumulate tobacco tar easily, the naked light in case certain layer of wind pipe scurried out enters other floors by shared flue collector easily.The measure that prior art addresses this problem is to be positioned at the fire resisting damper device of the installed inside of each air inlet position by torsion spring and fusible link or the control of fuse piece extension bolt at the main exhaust flue, when the intensity of a fire or temperature surpass 70 ℃, fire-protection valve in time closes down, avoid the intensity of a fire to enter venturi transformation pipe, enter public flue again, cause flue to catch fire or expand to explode and bring disaster upon and other floors because of high hot pressing.Because fire-protection valve is installed in the main exhaust flue, if hanging bolt, fusible link or fuse piece fused, change quite trouble of operation.
The utility model content
The purpose of this utility model is to provide a kind of external fire resisting damper mounting structure of changing fusible link or the simple transformation exhaust apparatus of fuse piece extension bolt.
The technical scheme that the utility model adopted is: a kind of external fire resisting damper mounting structure of transformation exhaust apparatus, comprise valve and venturi pressure swing type exhaust assembly by torsion spring and fusible link or the control of fuse piece extension bolt, it is characterized in that fire resisting damper is serially connected with between the air inlet of the air outlet of indoor exhaust device and venturi pressure swing type exhaust assembly, or valve is loaded in the venturi pressure swing type exhaust assembly air inlet, this air inlet is positioned at outside the main exhaust flue.
Described fire resisting damper is made individual components, having cross section is rectangle or circular tubular valve body, the valve body inner roof wall is provided with round bar, be with fire-protection valve on the round bar by torsion spring control, fire-protection valve is connected by fusible link with the inner roof wall of valve body fits both, torsion spring is in pre-application of force state, and two ends of valve body interlocks with air inlet and check valve tail end respectively.
Also valve body and venturi pressure swing type exhaust assembly air inlet can be made one, inner roof wall at venturi pressure swing type exhaust assembly air inlet is installed with round bar, be with fire-protection valve on the round bar by torsion spring control, torsion spring is in pre-application of force state, and fire-protection valve is connected by fusible link with the inner roof wall of venturi pressure swing type exhaust assembly air inlet fits both.
Because the utility model fire-protection valve is arranged on outside the exhaust uptake, in case fusible link blows, the fusible link that changes the outfit is very convenient.
Description of drawings
Fig. 1 is the mounting structure schematic diagram of the utility model fire resisting damper;
Fig. 2 is the mounting structure schematic diagram of another embodiment fire resisting damper of the utility model;
The specific embodiment
Describe concrete structure of the present utility model in detail below in conjunction with drawings and the specific embodiments:
Referring to Fig. 1, in the naked light inlet chamber that prevents under unexpected situation to produce in the exhaust uptake 5, or indoor naked light enters exhaust uptake 5 and brings disaster to other floors, and fire resisting damper need be set.Present embodiment is made individual components with fire resisting damper, has rectangular tubular valve body 95, the valve body inner roof wall is provided with round bar 92, be with fire-protection valve 9 on the round bar by torsion spring 93 controls, fire-protection valve 9 is connected by fusible link 91 with the inner roof wall of valve body 95 fits both, torsion spring 93 is in pre-application of force state, and the two ends of valve body 95 interlock with exhaust uptake 5 venturi pressure swing type exhaust assembly air inlet 22 and check valve 8 tail ends outward respectively.Valve 9 also can be arranged on valve body 95 left and right, under arbitrary wall in.
As another embodiment shown in Figure 2, valve body 95 and venturi pressure swing type exhaust assembly air inlet 22 are made one, inner roof wall at air inlet 22 is installed with round bar 92, be with fire-protection valve 9 on the round bar by torsion spring 93 controls, torsion spring 93 is in pre-application of force state, and the inner roof wall of fire-protection valve 9 and venturi pressure swing type exhaust assembly air inlet 22 is connected by fusible link 91 to be fitted both and keep passage unimpeded.Equally, valve 9 also can be arranged on air inlet 22 left and right, under arbitrary wall in.
If naked light occurs in the exhaust uptake 5, fusible link 91 is blown, fire-protection valve 9 under torsion spring 93 effects with pathway closure.Valve body 95 inner bottom surfaces are provided with block or blend stop 94, the location when being used for valve 9 and closing.Because fusible link 91 is positioned at the indoor location of the venturi pressure swing type exhaust assembly air inlet 22 outside the exhaust uptake 5, it is more convenient to change fusible link 91.
Mark 83 is the valve of check valve 8 among the figure, and mark 84 connects for the pipe that is connected with the discharge pipe of range hood, and mark 81 is the check valve valve body, and mark 21 is the air outlet of venturi pressure swing type exhaust assembly 2.
