TECHNICAL FIELD

[0001] The utility model relates to fire -fighting equipment technical field, concretely is a durable fire damper structure. BACKGROUND

[0002] The fire damper is a valve form that temperature control of memory alloy is closed by using the action of gravity and spring mechanism. In the new product, there is also the valve that is closed by using the deformation of memory alloy. Its function is that when the smoke temperature reaches 70 DEG C or 280 DEG C, people have basically evacuated, and there is no practical significance to exhaust smoke, but the smoke has fire at this time, and the valve is automatically closed to avoid the spread of fire.

[0003] The existing fire damper is in a high-temperature environment for a long time, and the steel structure often deforms to a certain extent, including the frame body and the blade. The deformation can cause the sealing property of the fire damper to be low, and can cause the fire damper to be unable to work normally in a serious case. SUMMARY

[0005] To achieve the above object, the utility model provides the following technical scheme: a durable fire damper structure, comprising: valve frame, electric actuator, pivot, blade piece, connecting seat, connecting rod,

[0006] The valve frame is the main frame structure of the fire damper, and the inside of the valve frame is a square mounting port,

[0007] The electric actuator is fixedly connected to the top of the valve frame,

[0008] The two ends of the pivot are movably connected to the inside of the valve frame through shaft sleeves, and the pivot is parallel and uniformly provided with at least two groups, one of which is fixedly connected to the rotating end of the electric actuator,

[0009] The blade piece is fixedly connected to the pivot, and the blade pieces are matched with each other,

[0010] The connecting seat is provided with one on the back of each blade piece,

[0011] The connecting rod is movably connected to each connecting seat through a pin,

[0012] The valve frame and the blade piece are sprayed with indoor intumescent steel structure fireproof paint on the surface.

[0013] Further, the two sides of the blade piece are separated to form matching connecting notches.

[0014] Compared with the prior art, the utility model has the advantages of:

[0015] 1. The durable fireproof valve structure of the utility model, through being sprayed with indoor expansion type steel structure fireproof paint on the valve body frame and the blade piece surface, can effectively prevent the valve body frame and the blade piece from deforming in long-term high temperature environment, guarantee the sealing property and service life of equipment.

[0016] 2. The durable fireproof valve structure of the utility model, through being separated into the mutually matched connecting notches on both sides of the blade piece, makes the blade piece connect closely with each other when closing, guarantees the sealing property and improves the use effect.

[0017] The utility model has the advantages of simple structure, safe and effective, good use effect and the like. ACCURACY OF DRAWINGS
