Description

Technical Field

[0001] The utility model relates to the technical field of fire valves, in particular to a louver type electric actuated fire valve. Background Art

[0002] A smoke exhaust fire damper is a fire protection component, generally installed on the pipeline of a mechanical smoke exhaust system. It is normally in an open state. When a fire occurs, it opens for smoke exhaust. When the smoke temperature in the smoke exhaust pipeline reaches 280 degrees, it closes and meets the requirements of smoke leakage and fire resistance integrity within a certain time, playing a role in isolating smoke and blocking fire.

[0003] There is a switch safety fire and smoke exhaust valve with the publication number of CN205190784U. In this patent, a switch protective cover is installed on the upper part of the valve body, positioned by a limit protrusion, and fixedly connected to the upper part of the valve body through a slot protrusion and a slot, playing a role in protecting the fire protection manual trigger. There is a handle on the upper part of the switch protective cover, which is used to open the switch protective cover. By rotating the fire protection manual trigger, the first connecting rod moves, then drives the movement of the second connecting rod, and then makes the blade support rod generate a rotation. The rotation of the blade support rod makes the blade rotate, completing the opening and closing of the ventilation duct. It can protect the switch of the fire and smoke exhaust valve with a metal box, making the switch in a safer state.

[0004] The inventor found in daily work that the above-mentioned fire and smoke exhaust valve needs to use a manual trigger to control the opening and closing of the blade. However, this manual component needs to be manually operated, resulting in certain safety hazards if it cannot be operated in time when a fire occurs. Summary of the Utility Model

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0013] 1. In the present utility model, by providing an auxiliary device, when the device needs to be used, first, when a fire occurs, the temperature sensor detects the high temperature and transmits the high-temperature signal to the control panel. When the control panel detects a high-temperature signal exceeding the preset value, it will control the motor to start. The motor starts to drive the first threaded rod to rotate. The first threaded rod rotates to drive the moving plate to move inside the chute. The moving plate moves inside the chute to drive the rack to move. The rack moves and meshes with the gear, thereby causing the gear to rotate. The gear rotates to drive the rotating shaft to rotate. The rotating shaft rotates to drive the louver to rotate.

[0021] To better understand the above-mentioned objects, features, and advantages of the present utility model, the following further describes the present utility model in conjunction with the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution: a louvered electric actuated fireproof valve, including a valve body 1, and connecting pipes 2 are fixedly installed on the outer wall surfaces on both sides of the valve body 1.

[0024] The following specifically describes the specific settings and functions of its auxiliary device 3 and adjustment device 4.

[0025] In this embodiment: an auxiliary device 3 is provided between the inner walls at the upper and lower ends of the valve body 1. The auxiliary device 3 includes two rotating shafts 301, and the two rotating shafts 301 are rotatably connected between the inner walls at the upper and lower ends of the valve body 1. Louver blades 302 are fixedly installed on the outer wall surfaces of the two rotating shafts 301.

[0026] In this embodiment: the setting of the rotating shaft 301 enables the louver blade 302 to rotate.

[0027] Specifically, two fixing plates 303 are fixedly installed on the top surface of the valve body 1. A first threaded rod 304 is rotatably connected between the two fixing plates 303. A motor 305 is fixedly installed on the surface of one of the fixing plates 303, and the output end of the motor 305 is fixedly connected to the first threaded rod 304.

[0028] In this embodiment: the setting of the motor 305 drives the first threaded rod 304 to rotate.

[0029] Specifically, a chute 306 is opened on the top surface of the valve body 1. A moving plate 307 is threadedly connected to the surface of the first threaded rod 304. A rack 308 is fixedly installed on the surface of the moving plate 307. Gears 309 are fixedly installed on the outer wall surfaces of the two rotating shafts 301. The rack 308 and the gears 309 are meshed with each other. A temperature sensor 310 and a control panel 311 are fixedly installed on one side surface of the valve body 1. The temperature sensor 310 and the control panel 311 are electrically connected, and the control panel 311 and the motor 305 are electrically connected. The setting of the rack 308 drives the gear 309 to rotate, and the setting of the gear 309 drives the rotating shaft 301 to rotate.

[0030] In this embodiment: Two adjusting devices 4 are provided on the top surface of the valve body 1. The two adjusting devices 4 include two grooves 41 which are opened on the top surface of the valve body 1. Two mounting plates 42 are slidably connected inside each groove 41, and mounting holes 43 are opened on the surface of each mounting plate 42. When it is necessary to adjust the positions of the two mounting plates 42 inside the grooves 41, first rotate the runner 46. The rotation of the runner 46 drives the rotation of the second threaded rod 45. Since the threads on the surface of the second threaded rod 45 are reverse threads centered on the runner 46, when the runner 46 drives the rotation of the second threaded rod 45, the two movable plates 48 threadedly connected to its surface will move away from or close to each other inside the strip-shaped groove 47. The movement of the two movable plates 48 away from or close to each other inside the strip-shaped groove 47 drives the two connecting rods 49 to move away from or close to each other. The movement of the two connecting rods 49 away from or close to each other drives the mounting plates 42 to move away from or close to each other inside the grooves 41. When the mounting plates 42 are moved to appropriate positions, the mounting operation of the device is carried out through the mounting holes 43 on the surfaces of the mounting plates 42. Through the cooperation of the above structures, the positions of the mounting plates 42 can be adjusted according to the actual installation environment, further improving the adaptability of the device during use.

[0031] Specifically, two support plates 44 are fixedly installed on both side surfaces of the valve body 1. A second threaded rod 45 is rotatably connected between every two support plates 44. A runner 46 is fixedly installed on the surface of the second threaded rod 45, and the threads on the surface of the second threaded rod 45 are reverse threads centered on the runner 46.

[0032] In this embodiment: The setting of the runner 46 plays an effect of driving the rotation of the second threaded rod 45.

[0033] Specifically, strip-shaped grooves 47 are opened on both side surfaces of the valve body 1. Two movable plates 48 are threadedly connected to the surface of the second threaded rod 45, and a connecting rod 49 is fixedly installed between the movable plate 48 and the mounting plate 42.

[0034] In this embodiment: The setting of the connecting rod 49 plays an effect of driving the mounting plate 42 to move inside the groove 41.

[0035] Working principle: By setting the auxiliary device 3, when the device needs to be used, first, when a fire occurs, the temperature sensor 310 detects the high temperature and conducts the high-temperature signal to the control panel 311. When the control panel 311 detects a high-temperature signal exceeding the preset value, it will control the motor 305 to start. The motor 305 drives the first threaded rod 304 to rotate. The rotation of the first threaded rod 304 drives the moving plate 307 to move inside the chute 306. The movement of the moving plate 307 inside the chute 306 drives the rack 308 to move. The rack 308 meshes with the gear 309, thereby causing the gear 309 to rotate. The rotation of the gear 309 drives the rotating shaft 301 to rotate. The rotation of the rotating shaft 301 drives the louver 302 to rotate. The rotation of the louver 302 completes the closing of the valve body 1. Through the cooperation of the above structures, the valve can be closed without manual operation when a fire occurs, reducing the probability of potential safety hazards. When it is necessary to adjust the positions of the two mounting plates 42 inside the groove 41, first rotate the rotating wheel 46. The rotation of the rotating wheel 46 drives the second threaded rod 45 to rotate. Since the threads on the surface of the second threaded rod 45 are reverse threads centered on the rotating wheel 46, when the rotating wheel 46 drives the second threaded rod 45 to rotate, the two movable plates 48 threadedly connected to its surface will move away from or close to each other inside the strip groove 47. The movement of the two movable plates 48 away from or close to each other inside the strip groove 47 drives the two connecting rods 49 to move away from or close to each other. The movement of the two connecting rods 49 away from or close to each other drives the mounting plate 42 to move away from or close to each other inside the groove 41. When the mounting plate 42 moves to a suitable position, the installation operation of the device is carried out through the mounting holes 43 on the surface of the mounting plate 42. Through the cooperation of the above structures, the position of the mounting plate 42 can be adjusted according to the actual installation environment, further improving the adaptability of the device during use.
