Description
Technical field
This utility model relates to a kind of smoke exhaust fire damper.
Background technology
Fire-protection valve is installed on the pipeline of ventilation, the sending of air conditioning system, return air or mechanical smoke extraction system.At ordinary times in opening, close when gas in pipelines temperature reaches 70 DEG C or 280 DEG C during fire, leakage smoke and fire integrity demands can be met within a certain period of time, play the effect every cigarette back-fire relief.At present, general smoke-exhaust fire valve is all to be welded by after processing and forming by Q235 iron plate.During production, in addition to existing and requiring the problem that after processing and forming, the flatness of iron plate is good in technique, there is also the problem being easily generated thermal deformation because of welding processing, thus bring the biggest difficulty of processing to the workman making product.Existing smoke exhaust fire damper often because of after processing the flatness of iron plate do not reach technological requirement, cause the inleakage of smoke-exhaust fire valve can not be up to state standards the requirement of regulation.During breaking out of fire, scene of a fire high temperature can make into plane metal blade and be deformed, and occurs that larger gap especially easily leaks cigarette in the mutual abutting portion of each blade, and inleakage does not reaches requirement.Therefore can not effectively stop spreading of flame and high temperature, bigger disaster can be caused.In view of this, a kind of smoke exhaust fire damper of invention is needed to solve the problems referred to above.
Utility model content
nullThe technical problems to be solved in the utility model，It is to provide a kind of smoke exhaust fire damper，Including valve body，Described valve body is provided with blade、Sharf、Connecting rod mechanism、Temperature inductor and actuator，Described temperature inductor is connected with actuator，Described connecting rod mechanism connects actuator，Described blade has three to be arranged into string，And be arranged in valve body by support，The most hinged sharf in the middle part of each blade，Each blade is all connected with connecting rod mechanism，Described actuator drives connecting rod mechanism rotate and then drive each blade to rotate around respective sharf，Each two adjacent blade rotation processes realize mutually abut and separate，The abutting portion that described each two adjacent blades mutually abut is provided with protection diving board，Described protection diving board is the arc mechanism of inner hollow，Described protection diving board outer surface has fireproof asbestos cloth；Wherein near two blades of valve interior wall, the one end each connected with valve body is also provided with the protection diving board with fireproof asbestos cloth, the position that described valve interior wall correspondence the two blade connects is equipped with abutting plate, and the bearing surface that the two abutting plate abuts against with corresponding blade is also with fireproof asbestos cloth.
Further, described actuator is provided with spring, and is connected with connecting rod mechanism by this spring.
Further, described temperature inductor is the temperature fuse of 280 DEG C.
Further, each blade is equipped with fire prevention fin.
Further, described actuator is provided with handle.
This utility model is by arranging the close blade of cooperation, each blade abutting portion is provided with the surface protection diving board with fireproof asbestos cloth, these protection diving boards utilize the hollow structure of self to have elasticity, when valve body is closed, the position mutually abutted is resilient contact, and elastic deformation, so contact closed seamless gap occur, inleakage greatly reduces, and effectively stops spreading of flame and high temperature.
Accompanying drawing explanation
This utility model is further described the most in conjunction with the embodiments.
Fig. 1 is overall structure schematic diagram of the present utility model；
Fig. 2 is the cross-sectional view of A-A in Fig. 1.
Detailed description of the invention
nullRefer to Fig. 1 and 2，It it is a kind of smoke exhaust fire damper as most preferred embodiment of the present utility model，Including valve body 1，Described valve body 1 is provided with blade 2、Sharf 4、Connecting rod mechanism 7、Temperature inductor 6 and actuator 5，Described temperature inductor 6 is connected with actuator 5，Described connecting rod mechanism 7 connects actuator 5，Described blade 2 has three to be arranged into string，And be arranged in valve body 1 by support 8，The most hinged sharf 4 in the middle part of each blade 2，Each blade 2 is all connected with connecting rod mechanism 7，Described actuator 5 drives connecting rod mechanism 7 to rotate and then drives each blade 2 to rotate around respective sharf 4，Each two adjacent blade 2 rotation processes realize mutually abut and separate，The abutting portion that described each two adjacent blades 2 mutually abut is provided with protection diving board 9，Described protection diving board 9 is the arc mechanism of inner hollow，Described protection diving board 9 outer surface has fireproof asbestos cloth；Wherein near two blades 2 of valve body 1 inwall, the one end each connected with valve body 1 is also provided with the protection diving board 9 with fireproof asbestos cloth, the position that described valve body 1 inwall correspondence the two blade 2 connects is equipped with abutting plate 3, and the bearing surface that the two abutting plate 3 abuts against with corresponding blade 2 is also with fireproof asbestos cloth.
Described temperature inductor 6 is the temperature fuse of 280 DEG C.Described actuator 5 is provided with spring, and be connected with connecting rod mechanism 7 by this spring, the elastic force of spring pulls connecting rod mechanism 7 (i.e. during temperature fuse fracture) reaching actuator 5 valve body 1 and require when, thus band moving vane 2 is closed.It is equipped with fire prevention fin 10 on each blade, slows down heat conduction rate, effectively slow down rate of rise in temperature, improve high temperature resistant grade.Described actuator is provided with handle, can be used for manual-lock fire resisting damper.
In sum, this utility model is by arranging the close blade of cooperation, each blade abutting portion is provided with the surface protection diving board with fireproof asbestos cloth, these protection diving boards utilize the hollow structure of self to have elasticity, and when valve body is closed, the position mutually abutted is resilient contact, there is elastic deformation, so contact closed seamless gap, inleakage greatly reduces, and effectively stops spreading of flame and high temperature.
Above in conjunction with accompanying drawing, this utility model is exemplarily described; obviously this utility model implements and is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model design is carried out with technical scheme; or the most improved design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
