Description

[Detailed description of the invention] This invention relates to a filling device for filling fire extinguishing liquid into the container of a liquid fire extinguisher, and is capable of easily and reliably supplying a fixed amount of fire extinguishing liquid into the container. We aim to provide the following.

A liquid fire extinguisher has a container 1 filled with extinguishing liquid 2 as shown in Figure 1.
When in use, open the valve with the lever 3 and use the pre-filled pressure gas, or open a small high-pressure gas cylinder (not shown) to release high-pressure gas and push out the extinguishing liquid through the siphon pipe 4 and hose 5 to extinguish the fire. It erupts towards the scene.

In such a liquid fire extinguisher, a fixed amount of extinguishing liquid 2 must be injected into the container 1, and a space 6 of sufficient volume must be left in the upper part of the container 1.

That is, if the amount of extinguishing liquid 2 injected into the container 1 is too small, the fire cannot be extinguished sufficiently, and conversely, if it is too large, the volume of the space 6 becomes small, and in the case of a pressure-accumulating fire extinguisher, the extinguishing liquid 2 is forced out. The amount of pressurized gas is insufficient for extinguishing, resulting in incomplete extrusion of extinguishing liquid.

In addition, in the case of a type of fire extinguisher that uses a separate pressure gas cylinder, if there is no space 6 above the extinguishing liquid, the pressure gas ejected from the cylinder will impact the container 1 and the lid 7 of the container. Very dangerous.

For this reason, conventionally, an indicator 8 was provided on the inner surface of the container 1, and the extinguishing liquid was poured into the container 1 using a funnel while the top surface of the extinguishing liquid was aligned with the indicator 8, or a pre-measured amount of extinguishing liquid was poured into the container 1. They were also injecting it into the body.

However, these operations are troublesome, and in some cases there is a risk of injecting too much fire extinguishing fluid.

The liquid fire extinguisher filling device of the present invention eliminates the above-mentioned inconveniences and enables even an inexperienced person to reliably and easily inject a fixed amount of fire extinguishing liquid into the container 1.

Hereinafter, the present invention will be explained with reference to drawings showing embodiments.

FIG. 2 is a side view showing a state in which fire extinguishing liquid is injected into the container 1 using the filling tool of the present invention, and FIG. 3 is a longitudinal side view showing the filling tool attached to the container 1.

The filling tool consists of a lid 9 that airtightly fits into the mouth 1a of the container 1, and two pipes 10 and 11 that hermetically pass through the lid 9. The upper end of one of the pipes 10 is connected to a hose 12. The pipe 11 communicates with a supply tank 13 for extinguishing liquid, and a float-type liquid control valve 14 is provided at the upper end of the other pipe 11 .

To explain in more detail, there is a 0-IJ song 5 on the lower outer peripheral surface.
Two pipes 10 hermetically penetrate the lid 9 which can be fitted to the mouth 1a of the container 1 airtightly and quickly.
, 11, the lower end of the pipe 10 with the hose 12 connected to the upper end has a length that reaches near the bottom of the container 1, and the lower end of the pipe 11 with the liquid stop valve 14 provided at the upper end is at the top of the container 1. It opens at a portion located slightly below the liquid level of the fire extinguishing liquid 2 that has been injected in a fixed amount.

The liquid stop valve 14 has a valve box 17 with a through hole 16 formed in the center thereof consisting of a large diameter part 16a in the lower half and a small diameter part 16b in the upper half. A spherical float 18 that floats on the liquid 2 is fitted loosely.

On the other hand, the upper end of a hose 12, one end of which is connected to the upper end of a pipe 10 whose lower end opens at the bottom of the container 1, is connected to a cock 19 at the bottom of a supply tank 13 provided at a position slightly higher than the container 1. .

Next, a procedure for injecting a fixed amount of fire extinguishing liquid into a container using the liquid fire extinguisher filling device of the present invention configured as described above will be described.

First, as shown in FIGS. 2 and 3, the lid 9 is attached to the opening 1 of the container 1.
a, open cock 19 and connect hose 12 and pipe 1.
0, the extinguishing liquid in the supply tank 13 is injected into the container 1.

A sufficient amount of fire extinguishing liquid is kept in the supply tank 13.

The amount of extinguishing liquid injected into the container 1 increases, and the liquid level in the container 1 rises, and the air in the container is pushed out through the pipe 11 and the through hole 16 of the valve box 17.

When the extinguishing liquid 2 reaches the lower end of the pipe 11, the air in the space 6 is no longer pushed out, and as the extinguishing liquid is injected, the pressure in the space 6 increases and the extinguishing liquid 2 flows into the pipe 11.
The float 18 of the liquid stop valve 14 floats up.

The flow t-18 floats inside the large diameter part 16a and flows into the small diameter part 16.
When b is closed, the flow of the extinguishing liquid 2 in the pipe 11 is stopped, and the injection force of the extinguishing liquid 2 into the container 1 through the pipe 10 is stopped phase-wise while leaving the space 6 in the upper part of the container.

In this state, a certain amount of extinguishing liquid is injected into the container 1, which is determined by the opening position of the flat end of the pipe 11.
Next, the cock 19 is closed, the lid 9 is removed from the container mouth 1a, and the pipes 10 and 11 are taken out from the container 1.

Since the liquid fire extinguisher filling device of the present invention is configured and used as described above, it is possible to easily and reliably fill the container 1 with a fixed amount of fire extinguishing liquid.

The supply tank 13 is installed so that at least the liquid level in the tank 13 is higher than the lower end opening of the pipe 11.

Preferably, if the liquid level of the supply tank 13 is installed at a position approximately 30 to 50 mm higher than the lower end of the pipe 11, stable quantitative supply of the extinguishing liquid can be performed at a low supply pressure.

In addition, the reason why the pipe 10 is inserted to the bottom of the container 1 is to prevent the fire extinguishing liquid injected into the container 1 through the pipe 10 from foaming in the container 1.
The pipe 10 may be short as long as this bubbling is prevented by, for example, opening the lower end of the pipe 10 toward the inner surface of the container 1 and allowing the fire extinguishing liquid to flow down along the inner surface.

Furthermore, the amount of extinguishing liquid injected into the container 1 can be adjusted using the pipe 1.
This can be easily done by adjusting the lower end opening position of No. 1.

Therefore, in the illustrated embodiment, the pipe 11 is
It is inserted into the lid body 9 through the 0-IJ song 0 in an airtight manner and its position can be adjusted in the vertical direction.
