Description

  The present invention relates to a fire extinguishing apparatus.

  As an example of a fire extinguishing apparatus, a package fire extinguishing apparatus including a pressurizing gas cylinder, a fire extinguishing agent filling container, and a fire extinguishing hose is known (for example, see Patent Document 1).

  A pressure regulator is provided on the secondary side of the pressurizing gas cylinder to adjust the pressure of the pressurized gas discharged from the pressurizing gas cylinder (for example, 15 MPa) to a predetermined pressure value (for example, 1 MPa). A fire extinguisher filling container is connected to the secondary side of the regulator, and the fire extinguisher filling container is connected to a fire hose.

  In the event of a fire, the operator opens the start valve of the pressurized gas cylinder. Then, the pressurized gas released from the pressurizing gas cylinder is regulated by the pressure regulator and introduced into the extinguishing agent filling container, and the extinguishing agent is released from the extinguishing agent filling container. Since this extinguishing agent is introduced into the extinguishing hose and sprayed from the extinguishing nozzle provided at the tip, the operator can extinguish the fire.

  In addition, the package fire extinguishing device is designed to prevent the extinguishing agent from being released from the inside of the extinguishing agent filling container to the outside such as the extinguishing hose due to the pressure increase in the extinguishing agent filling container based on the influence of temperature fluctuations during normal times. A relief valve for preventing pressure increase is provided. The relief valve opens and closes a discharge hole as a valve opening at a pressure lower than the pressure adjusted by the pressure regulator (for example, 0.03 MPa), thereby preventing normal pressure increase and during a fire. The fire extinguisher can be injected from the fire extinguishing nozzle through the fire extinguishing hose while maintaining the pressure increase in the fire extinguisher filling container (when the extinguishing agent is discharged). This relief valve is normally provided at the extinguishing agent discharge port of the extinguishing agent filling container.

Embodiment 1
Hereinafter, an embodiment of the present invention will be described. A package-type fire extinguisher as an example of a fire extinguisher includes a box-shaped main body 1 having an opening 1a on the front surface and a double door opening / closing door 2 that covers the opening 1a of the main body 1 so as to be freely opened and closed.

  A pressurization gas cylinder 7, a pressure regulator 9, a fire extinguisher filling container 3, a fire hose 4 and a fire extinguishing nozzle 5 are provided in the housing.

  The pressurization gas cylinder 7 is a tank filled with a pressurization gas having a pressure value of, for example, 15 MPa, and the pressurization gas is released by opening a normally closed manual start valve 7a.

  The pressure regulator 9 is connected to the secondary side of the pressurization gas cylinder 7 and adjusts the pressure of the pressurization gas released from the pressurization gas cylinder 7 to a pressure of a first pressure value (for example, 1 MPa). Release from the secondary side.

  The extinguishing agent filling container 3 is a tank filled with a foam extinguishing agent as an extinguishing agent, and two tanks are provided in this embodiment. The extinguishing agent filling container 3 introduces the pressurized gas into the extinguishing agent filling container 3 through the pressurized gas introduction pipe 10, and the foam extinguishing agent is released into the discharge collecting pipe 11 by this pressurizing action.

  The fire-extinguishing hose 4 is a rubber hose having a shape retaining performance, for example, a cross section perpendicular to the length direction having a hollow circular shape. The extinguishing hose 4 is connected at its proximal end to the extinguishing agent filling container 3 through the discharge collecting pipe 11, and the extinguishing nozzle 5 is provided at the tip. The fire-extinguishing hose 4 introduces the foam fire-extinguishing agent released from each fire-extinguishing agent-filled container 3 into the fire-extinguishing hose 4 via the discharge collecting pipe 11.

  The fire-extinguishing hose 4 is lowered from the base end toward the lower part of the casing, and is then raised around the outer periphery of the casing toward the upper part of the casing. And is wound and stored along the inner wall of the hose storage portion 6.

  The fire-extinguishing nozzle 5 has a normally closed manual lever 5a that is operated to release fire-extinguishing foam (extinguishing liquid) generated by the foam fire-extinguishing agent from the fire-extinguishing nozzle 5. The fire-extinguishing nozzle 5 includes a low-foaming water discharge portion 5b that generates and discharges a low-foaming foam (low foaming) of 5 to 20, for example, and a relatively high foaming ratio of 20 to 80, for example. And a middle foaming water discharge part 5c that generates and discharges (medium foaming).

  Between the pressure regulator 9 and the extinguishing agent filling container 3 (pressurized gas introduction pipe 10), a gate valve 20, a pressure increase preventing relief valve 30, and a purge valve 40 are provided. A gate valve 20 is connected to the proximal end of the pressurized gas introduction pipe 10, a relief valve 30 is connected to the primary side of the gate valve 20, a purge valve 40 is connected to the primary side of the relief valve 30, and the primary of the purge valve 40. The secondary side of the pressure regulator 9 is connected to the side. Note that the relief valve 30 and the purge valve 40 may have their arrangement positions reversed.

  The gate valve 20 is a manually operated ball valve, for example, which is normally open and does not block the flow path from the pressure regulator 9 to the fire extinguisher filling container 3 via the pressurized gas introduction pipe 10. The pressurized gas from the pressure regulator 9 is introduced into the fire extinguisher filling container 3. On the other hand, it is closed during inspection, shuts off the flow path between the pressure regulator 9 and the extinguishing agent filling container 3, and pressurizes from the pressure regulator 9 via the pressurized gas introduction pipe 10. The gas is not introduced into the extinguishing agent filling container 3.

  The relief valve 30 has a piping part 31 as a T-shaped pipe and a main body 33. The piping part 31 is provided with a branch pipe 31b having an opening 31a orthogonal to the passage path of the pressurized gas, and a main body 33 is screwed to the branch pipe 31b via an O-ring 32.

  The main body 33 is continuously provided with a ball storage portion 34, a spring storage portion 35, and a discharge hole 36 so as to penetrate the inside. These inner diameters are smaller in the order of the ball storage portion 34, the spring storage portion 35, and the discharge hole 36.

  The ball storage portion 34 stores a ball 37 slidably therein. The outer diameter of the ball 37 is smaller than the inner diameter of the ball storage portion 34 and larger than the inner diameter of the spring storage portion 35. The ball storage portion 34 is closed at one end facing the opening 31a by a ball press plate 38 having a plurality of communication holes 38a, and a packing 39 having an inner diameter substantially the same as that of the spring storage portion 35 is provided at the other end. It is done.

  The spring storage portion 35 stores, for example, a coiled spring 35a having substantially the same diameter as the spring storage portion 35. The spring 35 a abuts on the ball 37 and urges the ball 37 toward the ball pressing plate 38.

  The ball 37 is always in contact with the ball pressing plate 38 by the urging force of the spring 35a. In this state, since the outer diameter of the ball 37 is smaller than the inner diameter of the ball storage portion 34, the fluid such as the pressurized gas in the piping portion 31 is free from the opening 31 a, the communication hole 38 a, the ball 37 and the ball storage portion. 34 is discharged to the outside through the discharge hole 36 via the gap 34 and the spring storage portion 35.

  On the other hand, for example, when a reaction force of 0.03 MPa or more as the second pressure value is generated in the ball 37, the spring 35 a contracts and the ball 37 contacts the packing 39. In this state, fluid such as pressurized gas in the pipe portion 31 is not discharged to the outside through the discharge hole 36 because the ball 37 closes the communication between the ball storage portion 34 and the spring storage portion 35.

  With the above configuration, the relief valve 30 is opened at a pressure lower than the first pressure value (for example, 1 MPa) and lower than the second pressure value (for example, 0.03 MPa), so that the inside of the fire extinguisher-filled container 3 is opened. The normal pressure increase is prevented, and the pressure of the extinguishing agent filling container 3 is increased by the pressurized gas introduced from the pressure regulator 9 by closing at a pressure equal to or higher than the second pressure value (for example, 0.03 MPa). Can be held.

  Next, the purge valve 40 includes a piping part 41 and a cap 42. The piping part 41 is provided with a branch part 41b having an opening part 41a orthogonal to the passage path of the pressurized gas, and a cap 42 is screwed to the branch part 41b.

  The cap 42 is provided with a pressing hole 43, and a push button 44 is disposed in the pressing hole 43. A spring 45 is provided between the opening 41a and the push button 44 to urge the push button 44 toward the push hole 43 side.

  The push button 44 is always in contact with the pressing hole 43 by the biasing force of the spring 45. In this state, fluid such as pressurized gas in the piping part 41 is not discharged from the pressing hole 43 to the outside.

  On the other hand, when the operator pushes the push button 44, the spring 45 contracts and a gap is formed between the push button 44 and the push hole 43, so that fluid such as pressurized gas in the pipe portion 41 is opened. It is discharged from the pressing hole 43 to the outside through a gap between the portion 41 a, the push button 44 and the pressing hole 43.

  With the above configuration, the purge valve 40 can be purged of the pressure in the flow path between the pressure regulator 9 and the gate valve 20 by being operated at the time of inspection or the like. In addition, an O-ring or the like can be provided between the push button 44 and the press hole 43 to improve the airtightness. Further, the purge valve 40 may have a structure in which a normally closed manual ball valve is screwed to the branch portion 41 b instead of the cap 42.

  Next, the operation of the package fire extinguisher of the present embodiment will be described. First, at the normal time, the lever 5a is closed, the start valve 7a is closed, and the gate valve 20 is opened. In this state, when a minute pressure increase (less than 0.03 MPa) occurs in the fire extinguisher filling container 3 based on the fluctuation of the environmental temperature, the discharge hole 36 of the relief valve 30 is not blocked by the ball 37. The pressure of the increased pressure is discharged to the outside through the pressurized gas introduction pipe 10 and from the discharge hole 36 of the relief valve 30, so that the inside of the fire extinguisher filling container 3 can be maintained at the normal atmospheric pressure. it can. Thereby, the foam extinguishing agent in the extinguishing agent filling container 3 is not released to the outside such as the extinguishing hose 4.

  When a fire occurs, the operator first opens the opening / closing door 2 and opens the start valve 7a. Then, the pressurized gas from the pressurizing gas cylinder 7 is adjusted to a pressure of a first pressure value (for example, 1 MPa) by the pressure regulator 9 and is put into each extinguisher filling container 3 through the pressurized gas introduction pipe 10. be introduced. Then, the foam extinguishing agent in each extinguishing agent filling container 3 is introduced into the extinguishing hose 4 through the discharge collecting pipe 11. At this time, since the ball 37 is seated on the packing 39 and the pressure leakage from the discharge hole 36 does not occur, the relief valve 30 maintains the pressure increase of the extinguisher filling container 3 by the pressurized gas introduced from the pressure regulator 9. can do. Next, the operator holds the fire-extinguishing nozzle 5 in his / her hand and pulls out the fire-extinguishing hose 4 from the hose storage portion 6 and approaches the fire occurrence place. Then, the operator operates the lever 5a from a location a little away from the beginning, and discharges the fire-extinguishing foam (low foaming) from the low foaming water discharge part 5b. When the fire is moderated to some extent, the fire is approached and the fire is extinguished by operating the lever 5a to release the fire-extinguishing foam (medium foam) from the middle foaming water discharge part 5c. After the fire is extinguished, the operator closes the start valve 7 a and the lever 5 a and stores the fire hose 4 in the hose storage 6.

  At the time of inspection, the operator first closes the normally open gate valve 20. Next, in order to check the function of the relief valve 30, the normally closed start valve 7a is opened only slightly, and a pressurized gas having a pressure value less than the second pressure value (for example, 0.03 MPa) is supplied. It is introduced into the route to the gate valve 20. At this time, if the relief valve 30 is normal, the discharge hole 36 of the relief valve 30 is not closed, and the pressurized gas leaks from the discharge hole 36. The operator confirms this discharged sound and determines that it is normal. Moreover, you may judge that it is normal by making soap water etc. adhere around the discharge hole 36, and foaming.

  Next, the starting valve 7 a is further opened, and a pressurized gas having a first pressure value (for example, 1 MPa) adjusted by the pressure regulator 9 is introduced into the path to the gate valve 20. At this time, if the relief valve 30 is normal, the discharge hole 36 of the relief valve 30 is closed, so that the pressurized gas does not leak from the discharge hole 36. The operator confirms that there is no discharge sound and determines that the sound is normal. Further, normality may be determined by adhering soap water or the like around the discharge hole 36 so as not to foam. If the relief valve 30 is abnormal, replace it. In this way, it can be confirmed whether the relief valve 30 for preventing pressure increase opens or closes at an appropriate pressure value.

  At this time, it is possible to confirm whether or not the first pressure value (for example, 1 MPa) adjusted by the pressure regulator 9 is an appropriate value by visually observing the secondary pressure gauge 9a of the pressure regulator 9. it can. If it is not an appropriate value, the first pressure value is set to an appropriate value by operating the pressure adjustment knob 9b while visually observing the secondary pressure gauge 9a. As described above, the function check of the fire extinguishing device can be performed without removing each of the pressure regulator 9 and the relief valve 30 from the device.

  After the function check is completed, the operator closes the start valve 20 and then presses the push button 44 of the purge valve 40 to purge the pressure in the flow path between the pressure regulator 9 and the gate valve 20. Finally, the device is returned to the normal state by opening the gate valve 20.
