Abstract
The utility model discloses a fire prevention valve outside, including the shell, the shell lateral wall is provided with the shell cotter way, and the shell lateral wall is installed and is hung the handle, and hangs and be connected through the bearing between handle and the shell, hangs the handle lateral wall and is provided with and hangs the handle cotter way, shell cotter way and hang the handle cotter way and pass through fixed pin fixed connection. The utility model discloses an inferior mould pressing forms, and trilateral all have a mould pressing outside, increases the intensity of valve, and non -deformable and bending are played the conflagration control action, can set up the electric signal of output, and the valve was closed when the temperature surpassed preset temperature value, and the linkage forced draught blower cuts out, and the valve leans on the temperature fuse of fusible metal to move and self -closing cuts off the air current, prevents fire spreading.
Description
Technical field
This utility model relates to a kind of fire resisting damper, is specially outside a kind of fire resisting damper, belongs to fire fighting equipment field.
Background technology
Development along with society; prevent fires more and more important; fire prevention can be effectively protected the life security of property and people; fire can produce substantial amounts of smog and high temperature when of generation; smoke-and fire-preventing valve is mainly used on the airduct of ventilation, air conditioning system; it is in " normally opened " state at ordinary times, when air themperature reaches 70 DEG C, is automatically switched off by fuse action in valve.Exhaust opening, exhaust smoke valve are mainly disposed on the pipeline of smoke evacuation system, or are arranged at the suction inlet of smoke exhaust fan, are closed at ordinary times, during breaking out of fire, by linkage, automatically turn on smoke evacuation.Fire resisting damper is arranged at the fans entrance of smoke evacuation system and ventilation and air conditioning system dual-purpose, is in " normally opened " state at ordinary times, can ventilate, when in pipeline, gas flow temperature reaches 280 DEG C, valve is automatically switched off by the temperature fuse action of fusible metal, cuts off air-flow, prevents fire spread.In place of the design of existing fire resisting damper comes with some shortcomings, the corner of fire resisting damper can not carry out one time punching molded, three limits are not provided with outside mold pressing, the intensity making valve is relatively low, it is easy to yielding and bending, there is certain potential safety hazard, therefore for the problems referred to above, it is proposed that outside a kind of fire resisting damper.
Utility model content
This utility model provides outside a kind of fire resisting damper, formed by one-step mould, three limits have outside mold pressing, increase the intensity of valve, it is unlikely to deform and bends, play fire control effect, output electric signal can be set, the valve closing when that temperature exceeding predetermined temperature value, linkage pressure fan closedown, the corner solving fire resisting damper can not carry out one time punching molded, three limits are not provided with outside mold pressing, the intensity making valve is relatively low, it is easy to yielding and bending occurs, there is the problems such as certain potential safety hazard.
In order to solve above-mentioned technical problem, this utility model provides following technical scheme:
This utility model provides outside a kind of fire resisting damper, including shell, the sidewall of described shell is provided with left plate, and the opposite side of described side wall of outer shell is provided with right plate, the top of described left plate is respectively provided with and the bottom of horizontal side plate with the top of described right plate, and described horizontal side plate is positioned at the sidewall of described shell.
As a kind of optimal technical scheme of the present utility model, the sidewall of described shell is provided with door-plate.
As a kind of optimal technical scheme of the present utility model, the top of described shell is provided with valve.
As a kind of optimal technical scheme of the present utility model, the top of described shell is provided with side plate.
This utility model is reached to provide the benefit that:
This utility model is mainly used on the airduct of ventilation, air conditioning system, is in " normally opened " state at ordinary times, when air themperature reaches 70 DEG C, is automatically switched off by fuse action in valve.Exhaust opening, exhaust smoke valve are mainly disposed on the pipeline of smoke evacuation system, or are arranged at the suction inlet of smoke exhaust fan, are closed at ordinary times, during breaking out of fire, by linkage, automatically turn on smoke evacuation.Fire resisting damper is arranged at the fans entrance of smoke evacuation system and ventilation and air conditioning system dual-purpose, is in " normally opened " state at ordinary times, can ventilate, when in pipeline, gas flow temperature reaches 280 DEG C, valve is automatically switched off by the temperature fuse action of fusible metal, cuts off air-flow, prevents fire spread.One-step mould forms, and three limits have outside mold pressing, increases the intensity of valve, is unlikely to deform and bends, play fire control effect, can arrange output electric signal, the valve closing when that temperature exceeding predetermined temperature value, and linkage pressure fan is closed.
Accompanying drawing explanation
Accompanying drawing is used for providing being further appreciated by of the present utility model, and constitutes a part for description, is used for explaining this utility model, is not intended that restriction of the present utility model together with embodiment of the present utility model.

Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is illustrated, it will be appreciated that preferred embodiment described herein is merely to illustrate and explains this utility model, be not used to limit this utility model.
Embodiment: as shown in Figure 1, this utility model provides outside a kind of fire resisting damper, including shell 3, the sidewall of shell 3 is provided with left plate 4, and the opposite side of shell 3 sidewall is provided with right plate 7, the top of the top of left plate 4 and right plate 7 may be contained within the bottom of horizontal side plate 5, and horizontal side plate 5 is positioned at the sidewall of shell 3.
The sidewall of shell 3 is provided with door-plate 6, and door-plate can play the effect intercepting flue gas, thus reaches fireproof function.
The top of shell 3 is provided with valve 1, and valve has the effect controlling door-plate.
The top of shell 3 is provided with side plate 2, and side plate is easy to fixing and installs shell.
This utility model is in use, three limit one-step moulds form, three limits have outside mold pressing, increase the intensity of valve, it is unlikely to deform and bends, play fire control effect, output electric signal can be set, the valve closing when that temperature exceeding predetermined temperature value, linkage pressure fan is closed, general fire resisting damper is arranged in passage of central air conditioner system, operation principle is that the temperature utilizing the pole fusible alloy installed on valve controls, utilize the effect of action of gravity and spring mechanism, when fire occurs, flame invasion air channel, high temperature makes the fusible alloy on valve melt, or make memorial alloy generation deformation make valve be automatically switched off, the occasion run through with fire compartment for air channel.
This utility model is reached to provide the benefit that:
