Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] As shown in Figure 1, Figure 2, Figure 3, and Figure 4, the present invention is a fire damper remote actuator, which includes an actuator assembly and an accessory assembly.

[0019] The above-mentioned executive component is a product of a patent No. ZL200620106001.5 applied by the inventor of this patent in 2006, and the name is: remote smoke exhaust valve actuator. The fire damper remote actuator designed this time is based on the original remote smoke exhaust valve actuator, and the accessory components used in conjunction with it have been improved. Therefore, here is a preliminary explanation of the implementation components, and will not be described in detail. Referring to FIG. 4 , it is a top view of the accessory assembly described in this embodiment after the outer cover is opened.

[0020] The accessory assembly on the rem...

Abstract

The invention discloses a long-distance actuating mechanism of a fireproof valve, comprising an actuating mechanism and an accessory component, wherein the accessory component comprises a bottom plate (1) and a rocker arm (9) for driving a blade main shaft (11) of the valve to rotate synchronously; and the middle part of the rocker arm (9) is rotatably matched with the bottom plate (1) which is provided with a temperature control device. According to the standard regulations, blades of the fireproof valve can be automatically closed in time according to the temperature level. The long-distance actuating mechanism of the fireproof valve belongs to the field of mechanical equipment.

Description

technical field [0001] The invention relates to a remote actuator for a fire damper in a building ventilation duct. Background technique [0002] Fire dampers are installed in the fire prevention and ventilation systems of general high-rise buildings. The fire dampers are equipped with blades and blade spindles that control the swing of the blades. The opening and closing of the valve can be realized by rotating the blade spindles. Different installation places have different requirements for fire damper actions. Currently, an actuator that can realize remote manual reset to open the valve and remote manual close of the valve is called: remote smoke exhaust valve actuator, and the patent number is ZL200620106001.5, can realize the functions of smoke exhaust and fire prevention. The structure designed in this patent needs to be matched with an accessory assembly during use to facilitate the execution of the opening and closing function of the fire damper valve. The accessory...
