Background technology
In important building,, generally be equipped with automatic fire alarm and treatment system for security needs, and on the corresponding site of air conditioner, flue gas exhaust pipeline, be provided with check fire valve, fire resisting damper is often opened at ordinary times, and when fire alarm occurring, the smog that burning produces is discharged by smoke discharging pipe; Air-flow reaches controlled temperature in pipeline, and temperature controller promotes valve and is latched in valve-off under the spring action, stops the intensity of a fire further to spread.The existing check fire valve pair turnover panel structures that adopt more, as Chinese utility model patent check fire valve, the patent No. is 200820125324, comprise the fire prevention base, be installed in the PLASTIC LAMINATED on the fire prevention base, be installed in the fuse link of fire prevention base inboard, be used to connect the bindiny mechanism of PLASTIC LAMINATED and fuse link, lampblack absorber interface pedestal and the retaining board that is installed on the lampblack absorber interface pedestal, bindiny mechanism comprises the support that is fixed on fire prevention base inboard, the torsion spring that is located at described support lower end be used to be connected PLASTIC LAMINATED, the connecting rod of torsion spring and fuse link, one end and the PLASTIC LAMINATED of connecting rod are rotationally connected, the other end of connecting rod is connected with fuse link, and the middle-end and the torsion spring of described connecting rod are rotationally connected.This utility model uses the torsion spring structure to connect PLASTIC LAMINATED and fuse link, but there is defective tightness in two turnover panel structure, and volume is bigger, and the problem of inconvenience is installed in pipeline.For this reason, those skilled in the art have done some improvement, China's utility model patent flue gas check fire valve, the patent No. is 200720114979.0, the valve body that comprises tubular, be hinged with the unidirectional turnover panel of covering at body cavity near the gas approach place, be provided with heat detector at valve outer wall, the hook upper end that is hinged in the valve body is linked with heat detector, in valve body, hide place, unidirectional turnover panel top and also be hinged with the ballast rod, the free end of this ballast rod matches with hook lower end hook portion, constitutes temperature induction type ballast closing organ, and the unidirectional turnover panel of this utility model can carry out the unidirectional non-return discharging of smog, when temperature is too high, heat detector can make the ballast rod fall to being pressed on the turnover panel, and the turnover panel sealing can't be stirred, and prevents propagation of flame, only need a heavy valve body and a turnover panel, compact conformation, volume is little, but whole when mounted valve can only be beaten on draught tube walls with setscrew, because it is very thin on the draught tube walls, often need draught tube walls is broken, and relatively more difficult when burrowing installation, install inconvenient.
The utility model content
The purpose of this utility model provides a kind of check fire valve that is used for the shared flue gas exhaust pipeline of high-rise building, solves the problem that existing apparatus exists.
For achieving the above object, the utility model is taked following technical scheme:
The check fire valve that is used for the shared flue gas exhaust pipeline of high-rise building, the valve body that comprises tubular, the ventilation duct that is communicated with valve body, on the ventilation duct outer wall, be provided with heat detector, in valve body, be provided with an also shaft coupling door bolt with a plurality of retaining teeth, and shaft coupling fastens an end with a bolt or latch and passes and be connected with heat detector from valve body wall, is provided with the unidirectional turnover panel of a plurality of coverings at body cavity gas approach place, and each hides unidirectional turnover panel and retaining tooth corresponding and the shaft coupling door bolt cooperates.
The unidirectional turnover panel of described covering is fixed on body cavity gas approach place by fixed axis or articulated joint.
Described valve body and ventilation duct vertical connection.
Unidirectional turnover panel of the present utility model can carry out the unidirectional non-return discharging of flue gas, if the fume emission pipe temperature continues to rise, heat detector can be controlled and the shaft coupling door bolt moves down, make the retaining tooth top on unidirectional turnover panel, make turnover panel sealing and can't overturn, prevent propagation of flame, the utility model only needs a heavy valve body and a turnover panel, compact conformation is easy to install.A plurality of unidirectional turnover panels are convenient to ventilate, and turnover panel is when turning over backward, and institute occupies little, can prevent that the foreign material that drop in the fume emission pipeline from blocking turnover panel, hinders circulation of air, install simple and convenient, firm and durable during use.
