PNEUMATIC FIRE AND GAS DAMPER}

The present invention is installed in the ventilation duct of ship and building bulkheads and the vents of the outer wall to block each residential facility and the entire residential area early from a specific fire-producing area, delaying the speed of flame, and reducing the evacuation speed of fire and firefighting equipment. It relates to a pneumatic automatic gas and a flame breaker to secure time until the approach.

Although many types of flame breakers are known in the art, this is because it is configured to close the braid (2) by only one automatic operation structure in the event of a fire, a lot of inconvenience in use.

The present invention is to solve the problem as described above is to cut off the braid (2) by the power cut off of the solenoid valve (9-3) and the shut-off structure to automatically turn off the braid (2) by the temperature at the time of fire Provides a pneumatic gas and flame breaker of a building to operate the braid (2) by the above three structures by granting a shut-off control, a recovery structure and a manual block and recovery structure by the manual control valve (10) to close It is to be done.

As shown in Figs.

A plurality of braids 2 are bonded to the shaft 3 to the casing 1 fixing the side seal 4 and the braid stopper 5 to the electric shaft 3 and the linkage link 6 to the link 6 '. The electric shaft 3 or the link 6 'is connected to the compressed air actuator 9-7 in the control box 9 in which the junction box 8 is fixed.

Manual control valve 10, appliance pipe 9-1, pressure regulator 9-2, solenoid valve 9-3, plunger which fixed compressed air of air compressor 11 to both sides of partition 12 Flows into the valve (9-4), the quick exhaust valve (9-5), the compressed air actuator (9-7) to maintain the braid (2) in the opened state,

The compressed air by the operation of the compressed air actuator (9-7), solenoid valve (9-3) and manual control valve (10) is discharged to the outside through the quick exhaust valve (9-5) to close the braid (2). I would have to.

Referring to the operation of the present invention as described above is as follows.

When compressed air is supplied from the compressed air storage tank or the air compressor (11), the compressed air is supplied to the pressure regulator (9-2), solenoid valve (9-3), and plunger valve (9) through the machine pipe (9-1). -4), through the quick exhaust valve (9-5) and limit switch (9-6) to reach the compressed air actuator (9-7).

When the compressed air reaches the compressed air actuator (9-7), the compressed air actuator (9-7) is rotated 90 degrees, the rotational force is transmitted to the link (6 ') and the linkage link (6), as shown in Figure 2 (b) The braid (2) that was kept open as shown in FIG. 2 is closed as shown in FIG. 2 (a) in the event of a fire to block the gas and flames. The operation of the electric braid (2) is operated in three ways as follows. do.

◎ Explanation by car cutoff

Inside the trigger (7) fuse close to the braid (2), a glass bulb (CLASS BULB), a kind of glass fuse, is connected to the plunger valve (9-4) by a stainless shaft, and then fired. When the external surface temperature of the sea glass valve is exposed for about 20 seconds at 68 ° C,

At this time, the compressed air is discharged through the ESCAPE ROUTE of the plunger valve (9-4), and in this state, the compressed air actuator (9-7) operates in the reverse direction of 90 degrees, and this driving force is linked to the linkage link. (6), the link (6 ') and the shaft (3) to keep the braid (2) closed.

At this time, the side chambers 4 located at both ends of the braid 2 seal the gap between the braid 2 and the casing 1 to suppress the ingress of harmful gases to the human body as much as possible.

◎ Description of remote control blocking and recovery

A solenoid valve (9-3) is installed inside the control box (9) to shut off the supply power (or all supply power) for the solenoid valve (9-3) in the immediate area or in all areas of the building when a specific area fire is detected. Compressed air is discharged through the ESCAPE ROUTE of the solenoid valve 9-3,

In this state, the compressed air actuator 9-7 operates in the reverse direction of 90 degrees to maintain the braid 2 in the closed state through the link 6 ′, the interlock link 6, and the shaft 3. .

At this time, the side seals 4 located at both ends of the braid 2 seal the gap between the braid 2 and the casing 1 to suppress the ingress of harmful gases to the human body as much as possible.

In addition, if there is a part of the equipment that is not exposed to the flame after the fire suppression or during the test operation, the solenoid valve (9-3) can be easily restored from a long distance.

◎ Explanation of manual block and recovery

Before supplying the compressed air to the machine pipe 9-1 of the control box 9, the manual control valves 10 are installed on both partitions 12 in the installation area of the present application so that both persons can escape in case of fire. By operating one of the manual control valve (10) of the manual control valve (10) provided in (12) to block the spread of flame and gas to other areas early,

In operation, when the handle (HANDLE) of the manual control valve 10 is rotated 90 degrees, the compressed air is discharged through the ESCAPE ROUTE of the manual control valve 10, and in this state, the compressed air actuator (9-7) Is operated in the reverse direction of 90 degrees so that the driving force keeps the braid closed through the link 6 ', linkage link 6 and shaft 3.

At this time, the side seal 4 located at both ends of the braid (2) seals the gap between the braid (2) and the casing (1) to suppress the entry of gas harmful to the human body to the maximum.

In addition, if there is a part of the device that is not exposed to the flame after the fire suppression or during the test operation, the handle of the manual control valve 10 is rotated 90 degrees to be easily recovered from a long distance.

As an additional function, the manual control valve 10 is always equipped with an indicator to indicate whether it is open or closed.

If you want to selectively add the function to check the opening and closing in the central control room can be installed a limit switch (9-6) inside the control box (9).

This invention is required to close the braid (2) by the operation of the compressed air actuator (9-7), solenoid valve (9-3) and the manual control valve 10 to shut off the gas and flames According to this, there is an effect that the operation can be selectively and certainly conveniently performed.
