Embodiment 1

[0034] see Figure 1~5 , a fire and smoke exhaust valve, including a valve body 1, a valve blade 3, a driving shaft 4 and a valve blade rotating shaft 2 are installed on the valve body 1, the driving shaft 4 and the valve blade rotating shaft 2 are perpendicular to each other, and a driving shaft 4 is installed on the driving shaft 4. Bevel gear 9, driven bevel gear 10 is installed on the end of valve disc rotating shaft 2 towards driving shaft 4, driving bevel gear 9 and driven bevel gear 10 mesh with each other, valve blade 3 is installed on valve disc rotating shaft 2.

[0035] In the present invention, when the driving shaft 4 is rotated, the driving bevel gear 9 on the driving shaft 4 drives the driven bevel gear 10 meshed with it to rotate, thereby driving the valve disc rotating shaft 2 to rotate, and the valve blade 3 turns from a horizontal state to a vertical state. Close the outlet on the inner frame of the valve body 1 to achieve the purpose of closing. At the same...

Embodiment 2

[0037] see Figure 1~5 , a fire and smoke exhaust valve, including a valve body 1, a valve blade 3, a driving shaft 4 and a valve blade rotating shaft 2 are installed on the valve body 1, the driving shaft 4 and the valve blade rotating shaft 2 are perpendicular to each other, and a driving shaft 4 is installed on the driving shaft 4. Bevel gear 9, driven bevel gear 10 is installed on the end of valve disc rotating shaft 2 towards driving shaft 4, driving bevel gear 9 and driven bevel gear 10 mesh with each other, valve blade 3 is installed on valve disc rotating shaft 2.

[0038] The valve blade 3 includes a valve plate 3-1, and the valve plate 3-1 is provided with a rotating shaft hole 3-3 through which the valve rotating shaft 2 passes, and the valve plate 3-1 is socketed in the valve plate through the rotating shaft hole 3-3. On the valve disc rotating shaft 2, the valve disc plate 3-1 is fixedly installed on the valve disc rotating shaft 2 through its rotating shaft hole ...

Embodiment 3

[0041] see Figure 1~5 , a fire and smoke exhaust valve, including a valve body 1, a valve blade 3, a driving shaft 4 and a valve blade rotating shaft 2 are installed on the valve body 1, the driving shaft 4 and the valve blade rotating shaft 2 are perpendicular to each other, and a driving shaft 4 is installed on the driving shaft 4. Bevel gear 9, driven bevel gear 10 is installed on the end of valve disc rotating shaft 2 towards driving shaft 4, driving bevel gear 9 and driven bevel gear 10 mesh with each other, valve blade 3 is installed on valve disc rotating shaft 2.

[0042] The valve blade 3 also includes a matching platform 3-2, which is a long plate-shaped body, and its thickness is slightly smaller than that of the valve plate 3-1, and the matching platform 3-2 is installed on the valve plate 3-1. The upper and lower ends of the valve blade 3 are fitted with the fitting platform 3-2, so that the two valve blades 3 form a stepped sealing surface in contact, so as to e...

Abstract

The invention relates to the field of firefighting equipment, in particular to a fireproof smoke discharge valve. The fireproof smoke discharge valve comprises a valve body and valve blades; a drivingshaft and a valve plate rotating shaft are mounted on the valve body; the driving shaft is perpendicular to the valve plate rotating shaft; a driving bevel gear is mounted on the driving shaft; a driven bevel gear is mounted at the end, towards the driving shaft, of the valve plate rotating shaft; the driving bevel gear is engaged with the driven bevel gear; and the valve blades are mounted on the valve plate rotating shaft. The fireproof smoke discharge valve is opened by adopting a manner of rotating single rotating shaft without adopting traditional connecting rod and rocking rod mechanisms; and the rotating shaft is not easy to damage such as deformation and wear, so that products are stable and reliable in use and long in service life.

Description

technical field [0001] The invention relates to the field of fire fighting equipment, in particular to a fire and smoke exhaust valve. Background technique [0002] The fire and smoke exhaust valve is a fire-fighting component. It is generally installed on the pipe of the mechanical smoke exhaust system. It is usually open. When a fire occurs, it will open the smoke exhaust. It meets the requirements of smoke leakage and fire integrity within a certain period of time, and acts as a smoke and fire barrier. [0003] The test requirements of "Compulsory Certification of Fire Protection Products" require that after 50 times of switch tests, the fire and smoke exhaust valves have no obvious deformation, wear and other damages that affect their sealing performance, and the blades can still be closed flexibly and reliably from the open position. At present, the existing fire prevention and smoke exhaust valves all drive the swing rod through the connecting rod to make multiple val...
