Description

Technical Field

[0001] The utility model relates to an interlocking multi-disc air duct valve, belonging to the technical field of air duct valves. Background Art

[0002] In order to prevent overload when the fan of the quenching equipment starts, generally, a switch valve at the fan outlet needs to be closed first and then opened after the fan starts. Moreover, setting an air duct valve can also immediately close the air cooling when the quenching air cooling function stops. The traditional air duct valve adopts a single-disc structure. When the valve is closed, the disc is prone to force deformation under the action of wind pressure, and at the same time, the force will be transmitted to the rotary cylinder, causing damage to the rotary cylinder.

[0003] Therefore, how to provide an interlocking multi-disc air duct valve is the research purpose of the utility model. Content of the Utility Model

[0004] Aiming at the deficiencies of the above technologies, the utility model provides an interlocking multi-disc air duct valve. The connecting rod mechanism of the disc adopts an interlocking design, so that the cylinder will not be stressed under the action of wind pressure, and the disc is more stable and not easy to deform.

One ends of the first disc, the second disc, the third disc and the fourth disc are connected in series through a connecting rod mechanism. A rotary cylinder is connected to one end of the second disc away from the connecting rod mechanism. The connecting rod mechanism includes a first connecting rod, a second connecting rod and a third connecting rod. Both ends of the first connecting rod are respectively hinged to one end of the first disc and the third disc through rotating plates. Both ends of the second connecting rod are respectively hinged to one end of the first disc and the fourth disc through rotating plates. Both ends of the third connecting rod are respectively hinged to both ends of the second disc and the fourth disc through rotating plates.

[0007] Further, both ends of the first disc, the second disc, the third disc and the fourth disc are rotatably arranged inside the air duct body through bearing seats.

[0008] Further, the rotary cylinder is connected to one end of the first disc or the third disc or the fourth disc away from the connecting rod mechanism.

[0009] Further, the second connecting rod is arranged outside the first connecting rod, and the third connecting rod is arranged inside the first connecting rod.

[0010] The beneficial effects of the present utility model are as follows: The connecting rod mechanism of the butterfly plate adopts an interlocking design, so that the cylinder will not be stressed under the action of wind pressure, and the butterfly plate is more stable and not easily deformed.

Detailed Embodiment

[0016] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the following will be further analyzed in conjunction with the attached Figures 1-4 drawings of the present utility model.

[0017] As Figures 1-4 shown, an interlocking multi-butterfly plate air duct valve, characterized in that: it includes an air duct body 10, the inner side of the air duct body 10 is provided with a first butterfly plate 20, a second butterfly plate 30, a third butterfly plate 40 and a fourth butterfly plate 50, one ends of the first butterfly plate 20, the second butterfly plate 30, the third butterfly plate 40 and the fourth butterfly plate 50 are connected in series through a connecting rod mechanism 60, and the end of the second butterfly plate 30 away from the connecting rod mechanism 60 is connected with a rotary cylinder 70, and the second butterfly plate 30 is driven to rotate by the rotary cylinder 70, so as to drive the first butterfly plate 20, the third butterfly plate 40 and the fourth butterfly plate 50 to rotate, realizing the opening and closing of the butterfly plate, the connecting rod mechanism 60 includes a first connecting rod 601, a second connecting rod 602 and a third connecting rod 603, both ends of the first connecting rod 601 are respectively hinged to one end of the first butterfly plate 20 and the third butterfly plate 40 through a rotating plate, both ends of the second connecting rod 602 are respectively hinged to one end of the first butterfly plate 20 and the fourth butterfly plate 50 through a rotating plate, and both ends of the third connecting rod 603 are respectively hinged to both ends of the second butterfly plate 30 and the fourth butterfly plate 50 through a rotating plate.

[0018] In this embodiment, preferably, both ends of the first butterfly plate 20, the second butterfly plate 30, the third butterfly plate 40 and the fourth butterfly plate 50 are rotatably arranged on the inner side of the air duct body 10 through bearing seats.

[0019] In this embodiment, preferably, the rotary cylinder 70 is connected to one end of the first disc plate 20, the third disc plate 40, or the fourth disc plate 50 away from the link mechanism 60, that is, the rotary cylinder 60 can be connected to any one of the first disc plate 20, the second disc plate 30, the third disc plate 40, and the fourth disc plate 50.

[0021] The specific principle of the present utility model: The disc plate is driven to open or close by the rotary cylinder 70. When the disc plate is in the closed state, the wind pressure borne by any one of the first disc plate 20, the second disc plate 30, the third disc plate 40, and the fourth disc plate 50 will be mostly transmitted to the link mechanism 60 to bear, and is offset by the frictional force between the first link 601, the second link 602, and the third link 603, thereby greatly reducing the pressure transmitted to the rotary cylinder 70, and the butterfly plate is also more stable and not easily deformed.
