Abstract
The utility model discloses a fireproof valve, which comprises a valve body and a group of blades arranged in the valve body, wherein an executing mechanism for driving the blades to turn is also arranged on the valve body, the adjacent blades are connected through a connecting rod mechanism, and a temperature sensor and a controller for controlling the work of the executing mechanism are also arranged on the valve body. In order to enhance the blade intensity and reduce the noise generated by the blades, bulges are respectively arranged at both sides of the blades. The fireproof valve has the advantages that the structure is simple, the sealing and plugging speed is high, in addition, the blade intensity is high, and the noise is low when the air quantity is great.
Description
Technical field
The utility model relates to a kind of fire protection equipment parts, especially relates to a kind of fire-closing valve.
Background technique
At present, how all to be provided with the fire-fighting ventiduct system in the building, in pipeline, to be provided with fire-closing valve, generally be installed in airduct passing fire wall place, play fire shutoff effect.But existing fire-closing valve is for guaranteeing plugging effect, and the valve blade diameter of installing in the fire-closing valve is how identical with the diameter of ventilation duct, and its valve blade middle part has a rotating shaft.Because the diameter of valve blade is bigger, complex structure, weight is big, makes its shutoff speed slower.And when ventilation volume was big, blade strength was not enough, and blade makes a noise greatly.
The model utility content
The purpose of this utility model provides a kind of fire-closing valve, solves the existing slow-footed problem of the many shutoff of fire-closing valve.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of fire-closing valve comprises valve body and is arranged on one group of blade in the valve body; Also be provided with the actuator that orders about the blade upset on the described valve body, connect by linkage mechanism between the described adjacent blades.
Further, also be provided with the controller of temperature sensor and control executing mechanism work on the described valve body.
For the noise of reinforced blade intensity and the generation of reduction blade, described blade both sides are provided with projection.
The beneficial effects of the utility model: because described valve body is provided with the actuator that orders about the blade upset, connect by linkage mechanism between the adjacent blades, described blade both sides are provided with projection.This fire-proof valve structure is simple, and shutoff speed is fast, and its blade strength height, and noise was little when air quantity was big.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is the organigram of the utility model fire-closing valve.
Fig. 2 is the sectional view of Fig. 1.
Among the figure: 1. valve body, 2. temperature sensor, 3. actuator, 4. linkage mechanism, 5. blade, 6. projection.
Embodiment
In the utility model, because described valve body is provided with the actuator that orders about the blade upset, connect by linkage mechanism between the adjacent blades, described blade both sides are provided with projection.Therefore this fire-proof valve structure is simple, and shutoff speed is fast, and its blade strength height, and noise was little when air quantity was big.
Claims (3)
1. a fire-closing valve comprises valve body and is arranged on one group of blade in the valve body; It is characterized in that: also be provided with the actuator that orders about the blade upset on the described valve body, connect by linkage mechanism between the described adjacent blades.
2. fire-closing valve as claimed in claim 1 is characterized in that: the controller that also is provided with temperature sensor and control executing mechanism work on the described valve body.
3. fire-closing valve as claimed in claim 1 or 2 is characterized in that: described blade both sides are provided with projection.
