Embodiment 1

[0075] refer to figure 1 with figure 2 , the fire damper includes a valve body 1, a valve core 2 and a limit mechanism 3, a rectangular ventilation channel 11 is formed on the valve body 1, several valve cores 2 are arranged along the height of the valve body 1, and each The spools 2 of each piece are all arranged in the ventilation channel 11, and the limit mechanism 3 is installed on one side of the valve body 1. The limit mechanism 3 is used to drive the spools 2 of each piece to rotate; wherein, when the spools 2 of each piece are in the When in the vertical state, each spool 2 is on the same vertical plane and completely closes the ventilation passage 11. When each spool 2 is in the horizontal state, the spools 2 of each stage are parallel to each other and the ventilation passage 11 can be conducted.

[0076] refer to figure 1 with image 3 , the valve body 1 is made of heat-conducting metal, which mainly includes a ventilation part 12 and a mounting part 13, the ven...

Embodiment 2

[0095] refer to Figure 10 The difference between this embodiment and Embodiment 1 is that a rack portion 545 is provided on the side of the limiting member 54 close to the rotating shaft 22, and a gear 221 is installed on the part of the rotating shaft 22 located in the installation cavity 131. When the molten metal piece 52 is in a complete state, the rack provided on the limiter 54 can mesh with the gear 221, so that when the limiter 54 is driven upward by the heat conduction box 4, the gear 221 can drive the rotating shaft 22 to rotate.

[0096] Compared with Embodiment 1, this embodiment can make the connection between the limiting member 54 and the rotating shaft 22 more stable, and ensure the reset effect of the rotating shaft 22 .

Embodiment 3

[0098] refer to Figure 11 The difference between this embodiment and Embodiment 1 is that the end of the rotating shaft 22 penetrating into the installation cavity 131 is provided with a beveled surface 222 , and the plane where the beveled surface 222 is located is parallel to the axis of the rotating shaft 22 .

[0099] When each spool 2 is in a vertical state, the plane where the beveled surface 222 is located is basically horizontally arranged, and the beveled surface 222 is located on the lower side of the rotating shaft 22, and the limiter 54 can be moved upwards against the edge of the beveled surface 222, thereby The effect of driving the rotating shaft 22 to rotate is achieved.

[0100] When the spools 2 are separated from each other, the plane where the beveled surface 222 is located is inclined, and the part where the upper side of the beveled surface 222 is in contact with the outer wall of the rotating shaft 22 is in contact with the side of the stopper 54 protru...

Abstract

The fireproof valve convenient to reuse relates to the technical field of fire fighting equipment, and comprises a valve body, valve elements and a limiting mechanism, a rectangular ventilation channel is formed in the valve body, a plurality of valve elements are arranged in the height direction of the valve body, all the valve elements are arranged in the ventilation channel, the limiting mechanism is installed on one side of the valve body, and the limiting mechanism is installed on the other side of the valve body. The limiting mechanism is used for driving all the valve elements to rotate. When all the valve elements are in the vertical state, all the valve elements are located on the same vertical face and completely seal the ventilation channel, and when all the valve elements are in the horizontal state, all the valve elements are parallel to one another, and the ventilation channel can be communicated. The device has the effect of being convenient to reuse.

Description

technical field [0001] This application relates to the technical field of firefighting equipment, in particular to a fire damper and smoke prevention system that are easy to reuse. Background technique [0002] The fire damper is a normally closed valve, which is opened by the control center through 24V DC or manually, and it will automatically close at 280 ° C, and the reset must be done manually. Its function is: when the temperature of the flue gas reaches 280°C, the evacuation of the people has been basically completed, and the smoke exhaust has no practical significance. At this time, the flue gas is already on fire, and the valve is automatically closed to avoid the spread of the fire. The smoke exhaust outlet of the system can also use a normally closed fire-proof smoke exhaust outlet, and the smoke exhaust fire damper on the branch pipe is cancelled. In the event of a fire, the air outlet is opened by the control center through 24V DC or opened manually. When the sm...
