Embodiment 1

[0047] Such as Figure 1-Figure 4 As shown, the smoke and fire damper actuator provided by the embodiment of the present invention includes: a first elastic member 11, a second elastic member 12, a main shaft rotating rod 21, a secondary rotating rod 22, a limit assembly 30 and a locking arm 40; the main shaft The rotary rod 21 is used to connect with the main shaft 72 of the vane 71 of the valve; the limit assembly 30 can be engaged with or separated from the main shaft rotary rod 21 .

[0048] The auxiliary rotary rod 22 has a first hinge point for hinged with the valve. The first elastic member 11 and the second elastic member 12 have one end hinged with the auxiliary rotary rod 22 respectively. The first elastic member 11 and the second elastic member 12 are located at the second On the same side of a hinge point, and the first elastic member 11 and the second elastic member 12 extend in the same direction; for example, in a specific embodiment, the first elastic member 11...

Embodiment 2

[0072] Embodiment 2 of the present invention provides a smoke fire damper, which includes blades and the smoke fire damper actuator provided in Embodiment 1 above. The main shaft rotary rod in the smoke fire damper actuator is connected to the main shaft of the blade.

[0073] Specifically, as Figure 2-Figure 4As shown, the smoke fire damper includes a housing 73 and a blade 71 installed in the housing 73. The blade 71 is hinged to the housing 73 through a main shaft 72. The main shaft rotary rod 21 in the smoke fire damper actuator and the main shaft of the blade 71 72 to drive the blade 71 to rotate, thereby controlling the opening or closing of the smoke fire damper.

[0074] In the smoke fire damper actuator, the locking arm is hinged to the housing of the valve, one end of the second elastic member is hinged to the auxiliary rotary rod, and the other end is fixed to the housing.

[0075] A plurality of vanes can be installed in the casing, and the plurality of vanes can...

Abstract

The invention provides a performing mechanism for a smoke exhausting and fireproofing valve and the smoke exhausting and fireproofing valve, and relates to the technical field of smoke exhausting andfireproofing valves. The performing mechanism for the smoke exhausting and fireproofing valve and the smoke exhausting and fireproofing valve solve the problem that the tension force of an opening tension spring and the tension force of a closing tension spring are limited to each other, resulting in insufficient tension force. The mechanism comprises a first elastic part, a second elastic part, amain shaft rotating rod, a secondary rotating rod, a limiting assembly and a locking arm, wherein the limiting assembly can be clamped with or separated from the main shaft rotating rod; one end of each of the first elastic part and the second elastic part is hinged with the secondary rotating rod; the other end of the first elastic part is hinged with the main shaft rotating rod; the other end of the second elastic part is connected to a valve housing; and two sides of a second hinging point on the locking arm are correspondingly lapped with the secondary rotating rod and a fuse protector. According to the mechanism, the first elastic part and the second elastic part are correspondingly hinged with the secondary rotating rod and extend in the same direction, so that the first elastic part and the second elastic part are prevented from insufficient tension force due to mutual tension force limitation.

Description

technical field [0001] The invention relates to the technical field of a smoke exhaust fire damper, in particular to an actuator for a smoke exhaust fire damper and a smoke exhaust fire damper. Background technique [0002] Smoke fire dampers are usually installed in the smoke exhaust ducts of high-rise buildings and underground facilities. The smoke fire damper is usually closed. When a fire occurs, the fire control center supplies power to the actuator of the smoke fire damper. After the actuator is energized, the valve is controlled to open, and the smoke exhaust fan is started at the same time to exhaust the smoke to the building. Provide time for evacuation of personnel. When the exhaust gas temperature reaches 280°, the fuse on the valve will be closed to prevent the open flame from spreading from the pipeline to other non-fire areas. [0003] In the executive mechanism in the prior art, the main shaft rotating rod is connected with the main shaft of the blade of the...
