Embodiment 1

[0039] like Figure 1-Figure 4 As shown, the valve linkage device provided by the embodiment of the present invention includes: an electric actuator 10, a linkage rope 20 and a valve linkage mechanism, wherein:

[0040] The valve linkage mechanism includes a first linkage mechanism 30 and a second linkage mechanism 40 .

[0041] The electric actuator 10 is used to drive the first main shaft rotary rod 31 in the first linkage mechanism 30 to rotate.

[0042]The first linkage mechanism 30 is connected to the second linkage mechanism 40 through the linkage rope 20 , and the first linkage mechanism 30 drives the second spindle rotating rod 41 in the second linkage mechanism 40 to rotate through the linkage rope 20 .

[0043] The valve linkage device provided in this embodiment can be applied to valves, especially large smoke and fire dampers. Specifically, the first main shaft rotating rod in the first linkage mechanism and the second main shaft rotating rod in the second linkag...

Embodiment 2

[0069] like Figure 5-Figure 7 As shown, Embodiment 2 of the present invention proposes a smoke and fire damper, including several groups of valves, and the valve linkage device provided in Embodiment 1 above. The main shafts in each group of valves are respectively connected with the first linkage mechanism 30 Or the second linkage mechanism 40 is connected.

[0070] Specifically, in a specific implementation manner, each group of valves may be connected to the first linkage mechanism or the second linkage mechanism.

[0071] or, as in Figure 6 As shown, several valves are divided into multiple groups, each group includes a plurality of valves, and the valve plates 90 of the multiple valves in each group are connected by transmission, and each group has a valve plate 90 of a valve and the first linkage The mechanism 30 or the second linkage mechanism 40 are connected.

[0072] read on Figure 6 , preferably, the valve group also includes a transmission plate 91 and a tra...

Abstract

The invention provides a valve linkage device and a smoke-proof and fire-proof valve, and relates to the technical field of fire-proof valves. The technical problems that a large valve requires a plurality of electric actuating mechanisms and a driving current is strong existing in the prior art are solved to a certain degree. The valve linkage device comprises an electric actuating mechanism, a linkage rope and a valve linkage mechanism, the valve linkage mechanism comprises a first linkage mechanism and a second linkage mechanism, wherein the electric actuating mechanism is used for drivinga first main shaft rotating rod in the first linkage mechanism to be unlocked to rotate; the first linkage mechanism is connected with the second linkage mechanism through the linkage rope; and the first linkage mechanism drives the second linkage mechanism to be unlocked through the linkage rope to enable a second main shaft rotating rod to rotate. According to the valve linkage device, only thefirst linkage mechanism is started electrically, the second linkage mechanism is connected with the first linkage mechanism through the linkage rope, so the starting current required for the whole valve is smaller.

Description

technical field [0001] The invention relates to the technical field of fire dampers, in particular to a valve linkage device applied to a large-scale smoke and fire damper combined with multiple sets of valves and a smoke and fire damper using the valve linkage device. Background technique [0002] A smoke and fire damper is usually installed in the ventilation duct of the central air conditioner. The smoke and fire damper is normally open. When a fire occurs, the control center supplies power to the actuator of the smoke and fire damper, and the actuator releases the locking device to close the valve, preventing delay and fire spread. [0003] When the valve includes a large number of valve slices, it is necessary to divide the large valve into multiple small valves and combine them together, and each small valve must be equipped with an electric actuator to control the valve slices. It is necessary to control the rotation of the valve plate by multiple actuators, so as t...
