Valve, reaching prevents the purpose of fire spreading.
To achieve the above object, the utility model provides following technical scheme：
A kind of dead-weight fire resisting damper, it is characterised in that：A kind of described dead-weight fire resisting damper, including valve body 1；Described valve
Connecting rod 4, support 5 and fuse sheet 6 are configured with body 1；The support 5 is fixedly connected fire prevention sharf 3；The fire prevention leaf
Fire prevention blade 2 is configured with bobbin 3；One end away from fire prevention sharf 3 is configured with twist mechanism 7 on the fire prevention blade 2；Its
In, the connecting rod 4 is connected to fuse sheet 6 and fire prevention blade 2 by twist mechanism 7.
Further illustrated as to a kind of dead-weight fire resisting damper described in the utility model, it is preferable that the dead-weight
Material used in fire resisting damper is metal.
Further illustrated as to a kind of dead-weight fire resisting damper described in the utility model, it is preferable that the fuse sheet 6
Fusing be 280 degrees Celsius.
Further illustrated as to a kind of dead-weight fire resisting damper described in the utility model, it is preferable that the fire prevention leaf
The number of piece 2 be 2 and more than.
Further illustrated as to a kind of dead-weight fire resisting damper described in the utility model, it is preferable that the fire prevention leaf
Have on piece 2 and the only one fire prevention sharf 3.
It can be seen from above-mentioned technical scheme that, a kind of described dead-weight fire resisting damper, including valve body 1；In the valve body 1
It is configured with connecting rod 4, support 5 and fuse sheet 6；The support 5 is fixedly connected fire prevention sharf 3；The fire prevention sharf 3
On be configured with fire prevention blade 2；One end away from fire prevention sharf 3 is configured with twist mechanism 7 on the fire prevention blade 2；Wherein, institute
State connecting rod 4 and fuse sheet 6 and fire prevention blade 2 are connected to by twist mechanism 7.The utility model is normally opened shape at normal temperatures
State, when the environment temperature around fire resisting damper reaches more than 280 degrees Celsius, fuse sheet 6 fuses automatically, and fire prevention blade 2 is in gravity
In the presence of, connecting rod 4 can be driven to be rotated along fire prevention sharf 3, so as to close the dead-weight fire resisting damper, reaching prevents fire
The purpose that gesture spreads.
