Abstract
The invention discloses a smoke exhaust fireproof valve which comprises a valve frame; a valve assembly and a performer are arranged in the valve frame; the valve assembly comprises a connecting rod, a plurality of fireproof blades and blade shafts which correspond to the fireproof blades in number; the blade shafts are rotatably connected into upper and lower bottom plates of the valve frame; one fireproof blade is fixedly arranged on each blade shaft; the connecting rod is parallel to the valve frame; coupling rods arranged on the connecting rod are separately connected with the blade shafts; a vertical shaft is fixedly connected on the connecting rod; the performer comprises a performing mechanism used for keeping the valve assembly to normally open and a temperature fuse; the performing mechanism is arranged on the top of the valve frame; and the temperature fuse is arranged on the front surface of the valve frame, and is in circuit connection with the performing mechanism. The smoke exhaust fireproof valve disclosed by the invention has the beneficial effects that the valve assembly is in a normally-open state, so that ventilating effect at ordinary times is guaranteed; when a fire disaster happens, the valve assembly can be timely closed to avoid fire propagation and exhaust gas passing; and meanwhile, the adjacent fireproof blades have superposed parts, so that sealing effect during closing can be guaranteed.
Description
Technical field
The present invention relates to valve field, particularly relate to a kind of smoke exhaust fire damper.
Background technology
In smoke exhaust fire damper is generally used for having the air conditioning and smoke exhaust system air channel of fire protection requirement or the porch of smoke exhaust fan, flat
Time for being opened for ventilation state, after flue-gas temperature reaches described in 280, temperature fuse fuse, valve closing, block flue gas
Diffusion.
Existing smoke exhaust fire damper fire prevention blade design is unreasonable, it is impossible to completely enclose exhaust gases passes high temperature when,
Be easily caused fire spreads the diffusion with flue gas, it is therefore desirable to the smoke exhaust fire damper of a kind of invention.
Summary of the invention
In order to overcome drawbacks described above, the present invention provides a kind of smoke exhaust fire damper.
To achieve these goals, the technical scheme is that a kind of smoke exhaust fire damper, including valve frame, described valve
Being provided with valve member, executor in door frame, described valve member includes connecting rod, some fire prevention blades and the fire prevention corresponding number of blade
The sharf of amount, described sharf is rotationally connected with in valve frame upper and lower bottom plate, and each sharf is fixed with a fire prevention
Blade；Described connecting rod flap valve door frame is arranged, and connecting rod is provided with connecting rod and is connected with each sharf respectively；On described connecting rod admittedly
Determining connection has vertical axes, described valve frame base to be provided with projection, and projection is connected by extension spring with bottom vertical axes, described execution
Device includes that described actuator is arranged on valve frame top for keeping the normally opened actuator of valve member and temperature fuse
Portion, temperature fuse be arranged on valve frame front and with actuator connection.
Further, the fusing-off temperature of described temperature fuse is 280 DEG C.
Further, adjacent sharf is provided with intersection along connecting rod opening direction.
Further, the support body of described valve frame both sides is provided with the platform that the fire prevention blade with correspondence position coincides.
Further, described actuator is provided with manual controller.
The invention has the beneficial effects as follows: valve member is normally open, it is ensured that ventilation effect at ordinary times；During breaking out of fire,
In time valve member can be closed, it is to avoid fire spread and flue gas pass through, the most adjacent fire prevention blade mutual coincidence position, can
To ensure sealing effectiveness when closing.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the A-A view of Fig. 1.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described further.
As shown in Fig. 1 Fig. 2, a kind of smoke exhaust fire damper, including valve frame 1, it is provided with valve member in described valve frame 1, holds
Row device, described valve member includes connecting rod 4, some fire prevention blades 2 and the sharf 3 of fire prevention blade 2 respective amount, described leaf
Bobbin 3 is rotationally connected with in valve frame upper and lower bottom plate, and each sharf 3 is fixed with a fire prevention blade 2；Described connecting rod 4
Flap valve door frame 1 is arranged, and connecting rod 4 is provided with connecting rod 5 and is connected with each sharf 3 respectively；It is fixedly connected with on described connecting rod 4
Vertical axes 6, described valve frame 1 base is provided with protruding 7, protruding 7 and is connected by extension spring 8 with bottom vertical axes 6, described executor
Including for keeping the normally opened actuator 9 of valve member and temperature fuse 10, described actuator 9 is arranged on valve frame 1
Top, temperature fuse 10 be arranged on valve frame 1 front and with actuator 9 connection.The fusing of temperature fuse 10
Temperature is 280 DEG C.
In order to strengthen sealing effect when valve member is closed, adjacent sharf 3 is provided with coincidence along connecting rod 4 opening direction
Part.
As the improvement of above-mentioned technology, the fire prevention blade 2 that the support body of valve frame 1 both sides is provided with correspondence position coincides
Platform.
Non-follow control for convenience, actuator 9 is provided with manual controller 11, can pass through hand control valve member
Guan Bi and open.
Valve member is normally open, it is ensured that ventilation effect at ordinary times；During breaking out of fire, flue-gas temperature reaches 280 DEG C, temperature
Degree fuse 10 fuses, and valve member can be closed by actuator 9 in time, it is to avoid fire spread and flue gas pass through, same to phase
Adjacent fire prevention blade 2 mutual coincidence position, it is ensured that sealing effectiveness during closedown.
Technical scheme is not limited to the restriction of above-mentioned specific embodiment, every does according to technical scheme
The technology deformation gone out, within each falling within protection scope of the present invention.
