Detailed Description
Other objects and advantages of the present invention will become apparent from the following explanation of the preferred embodiments of the present application.
As shown in fig. 1 to 3, a remote-control normally-open fire damper includes a valve body 1 and a driving mechanism for opening or closing the valve body 1.
The driving mechanism comprises a driving sheet 2, a fusible rod 9 and a pull rope 11. The fusible rod 9 is fixed outside the outer frame 101 and is connected with the outer frame 101 in a heat transfer manner. When the temperature of the gas in the pipe is too high to exceed the melting point of the fusible rod 9, the fusible rod 9 fuses. One end of the pull rope 11 is connected with the remote controller 7, and the other end of the pull rope bypasses the fusible rod 9 to be connected with the driving sheet 2.
The driving plate 2 comprises a first end 201 and a second end 202 arranged opposite to each other. The pull cord 11 is connected to the first end 201 of the driving piece 2. The middle part 203 of the driving plate 2 between the first end part 201 and the second end part 202 is fixedly connected with the rotating shaft 3, and the driving plate 2 can drive the rotating shaft 3 to rotate so as to open/close the valve body 1. The driving mechanism further comprises a tension spring 6, one end of the tension spring 6 is connected with the outer frame 101, and the other end of the tension spring 6 is connected with the second end 202 of the driving sheet 2. As shown in fig. 1, when the temperature of the gas in the pipe is normal, the tension spring 6 is in a tensioned state.
As shown in fig. 4, the driving mechanism further includes a pulley 10, the pulley 10 is rotatably connected to the fusible link 9, the pull rope 11 passes around the pulley 10, and the pulley 10 can reduce the friction between the pull rope 11 and the fusible link 9 when the remote controller 7 can normally operate. A stopper ring 12 is provided at the upper end of the fusible rod 9 on the upper side of the pulley 10 to limit the pulley 10.
As shown in fig. 5, one end of the fusible rod 9 extends into the inside of the outer frame 101 through the wall of the outer frame 101, so that the temperature of the gas in the internal passage of the fire damper can be accurately transferred to the fusible rod 9.
In some embodiments, the remote-control normally-open fire prevention valve further comprises a temperature sensor, wherein the temperature sensor is connected with the valve body 1 and is used for detecting the temperature of gas in the valve body 1. As shown in fig. 6, the temperature sensor is connected to the remote controller 7, transmits the gas temperature detected by the temperature sensor to the remote controller 7, and when the gas temperature reaches a first threshold value, the remote controller 7 releases the pull cord 11.
As shown in fig. 7, when the remote controller 7 cannot normally operate, the fusible link 9 is fused when the gas temperature reaches a second threshold value, and the first threshold value is smaller than or equal to the second threshold value.
The utility model discloses a fire prevention valve is normally opened in remote control, if the too high situation of gas temperature in the pipeline, when remote controller 7 can normally work, remote controller 7 passes through 11 release driving lugs 2 of stay cord. The extension spring 6 pulls the driving plate 2 to rotate, the driving plate 2 further drives the rotating shaft 3 to rotate, automatic closing of the fire damper is achieved, and the limiting rod 8 is used for limiting the rotation limit position of the driving plate 2. When the remote controller 7 can not work normally, after the gas temperature in the pipeline reaches or exceeds the melting point of the fusible rod 9, the fusible rod 9 is fused, the tension spring 6 pulls the driving piece 2 to rotate, and the fire-proof valve is closed. Therefore, the utility model discloses a fire prevention valve is normally opened in remote-control also can self-closing when remote control 7 became invalid, has higher factor of safety and reliability.
The apparatus of the present application has been described in detail with reference to the preferred embodiments thereof, however, it should be noted that those skilled in the art can make modifications, alterations and adaptations based on the above disclosure without departing from the spirit of the present application.
