Embodiment Construction

[0014] like figure 1 As shown, the present invention discloses a fire damper, comprising a rectangular valve frame surrounded by two parallel horizontal frame rods 1 and two parallel mullion rods 2 and a valve frame rotatably connected between the two mullion rods 2 Several valve slices 3 connected to the rotating rod 5 through the fixed piece 6, and the actuator 4 fixed on the valve frame control the rotation of the rotating rod 5 through the actuator 4, thereby controlling the opening and closing of the valve slice 3 to To realize the opening and closing of the fire damper, to sum up, it is basically consistent with the structure of the existing common fire damper.

[0015] like figure 2 As shown, the fire damper of the present invention is mainly innovative in that the transverse frame rod 1 includes a long and narrow main rod body 11, and the two long sides of the main rod body 11 have anti-bending reinforcement sheets 12 respectively. The two short sides of the main ro...

Abstract

The invention discloses a fireproof valve. The fireproof valve comprises a rectangular valve frame defined by two parallel transverse frame rods and two parallel vertical frame rods and a plurality of valve pieces which are rotatably connected between the two vertical frame rods and are connected to rotating rods through fixing pieces; each transverse frame rod comprises a long and narrow main rod body, two long sides of each main rod body are each provided with a folding-resisting reinforcing piece, and connecting pieces are arranged on the two short sides of each main rod body; the middles of the fixing pieces are provided with protruding semicircular rod cavities, and anti-rotation buckles are arranged at one ends of the rod cavities and are matched with anti-rotation grooves in the rotating rods. The transverse frame rods and the vertical frame rods of the valve frame are made through a steel plate side bending method, the good folding resistance and bending resistance strength is achieved, meanwhile, the rods are folded into the connecting sides, and compared with a traditional welding manner, the fireproof valve has the beneficial effects that the production efficiency is improved, the material utilization rate is improved, and the weight of the fireproof valve is greatly reduced. Meanwhile, the fixing pieces are arranged, the valve pieces and the rotating rods cannot be relatively rotate.

Description

technical field [0001] The invention relates to a fire damper, in particular to a fire damper with high production efficiency, high material utilization rate and good sealing performance. Background technique [0002] The existing fire damper, its basic structure includes a rectangular frame and a valve disc that is rotatably connected to the frame, and a fire damper with a relatively large opening width will also be provided with one or more columns in the middle of the frame; the existing fire damper The frame is basically made of channel steel welding, the material cost is relatively high, the production quality is relatively rough, and the weight is relatively large, so it is not easy to carry. Contents of the invention [0003] In order to overcome the above defects, the present invention aims to provide a fire damper that adopts the hemming technology to make the frame and the column, so that it has the characteristics of small weight, good airtightness, and convenie...
