Description
Technical field
The utility model belongs to valve, specifically, being related to a kind of fire resisting damper.
Background technology
Fire resisting damper is a kind of temperature control of pole fusible alloy, the valve closed using the effect of gravity and spring mechanism
Door form.Also have in novel product makes valve close using memorial alloy generation deformation.
Its effect is：When flue-gas temperature reaches 280 DEG C, evacuation finishes people substantially, discharges fume without practical significance, and
Band is fiery at this time in flue gas, and valve is automatically closed, to avoid fire spreading.
Existing fireproof valve blade is mostly single layer, and intensity is low, and flatness is low, and seal is poor, is unusable in high-pressure system.
In view of this special to propose the utility model.
Invention content
The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a kind of fire resisting damper,
In order to solve the above technical problems, the utility model is using the basic conception of technical solution：
A kind of fire resisting damper, including valve body, valve deck, handle and twi-tier blade, the valve inner are provided with twi-tier blade, institute
It states twi-tier blade end to connect with handle, the handle is connected in valve deck, and the valve deck is located at the top of valve body, the bilayer
Blade is divided into upper layer blade and lower leave, and the upper layer blade is identical with the shape of lower leave, and the upper layer blade is under
Layer blade is distributed in mirror image, there is the cavity that upper layer blade and lower leave are formed in the twi-tier blade.
In the utility model, the number of the cavity is at least three.
In the utility model, the section position multistage broken line of the upper layer blade and lower leave.
In the utility model, together with the upper layer blade is fitted closely with lower leave.
In the utility model, the upper layer blade and lower leave are wavy.
After adopting the above technical scheme, the utility model has the advantages that compared with prior art.
The utility model bilayer reinforced fireproof valve blade, intensity is high, and flatness is high, and good leak tightness can be used in high pressure system
System.
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
