Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a small liquefied gas cylinder that is used by being connected to a burner device, a gas combustor, etc.

(Prior Art) A conventional liquefied gas cylinder of this type has a structure in which the cylinder body is filled with a porous liquefied gas absorbing material, and a mountain cap is provided with a valve device that also serves as a connecting member.

(Problems to be solved by the invention) In such a conventional structure, when the liquefied gas cylinder is used upside down, the liquefied gas impregnated in the liquefied gas absorber flows into the valve device as a liquid,
There was a risk that the amount supplied to the burner device or gas combustor would suddenly increase beyond the set amount, resulting in a large flame or incomplete combustion.

(Means for solving the problems) This invention was devised to solve the above-mentioned conventional problems, and its purpose was to solve some of the problems without changing the structure of the conventional liquefied gas cylinder. To provide a liquefied gas cylinder that can supply liquefied gas in gaseous form to a burner device or the like in any state by simply supplementing the gas.

This invention for the above purpose consists of connecting a gas conduit of the required length to the lower side of the valve device installed in the center of the mountain cap, and installing a gas conduit of the required length in the upper center of the porous liquefied gas absorbing material inside the cylinder body. A vertical hole is formed with a depth such that the open end of the gas conduit is located with a required space between it and the bottom surface, and the gas conduit is accommodated in the vertical hole with a space provided around it.

(Function) In the above structure, a space is always secured between the open end of the gas conduit that serves as the suction port of the valve device and the bottom of the vertical hole, and the liquefied gas impregnated in the liquefied gas absorbing material is in a gas state. into the conduit. Furthermore, the above space does not change even if the cylinder body is reversed, and liquefied gas does not directly flow into the gas pipe from the liquefied gas absorbing material, so the liquefied gas remains in gaseous form regardless of the condition of the cylinder body. It will be supplied to the valve device.

(Example) In the figure, 1 is a cylindrical cylinder body, the inside of which is filled with a liquefied gas absorbing material 2 such as maltprene or felt. Further, a valve device 4 which also serves as a connecting member is attached to the center of the mountain cap 3 that closes the opening of the cylinder body 1.

This valve device 4 has a closing member 5 and a spring member 6 inside a main body which is threaded around the periphery. A gas conduit 7 having a length of 100 mm is integrally connected.

Further, a vertical hole 8 for accommodating the gas conduit 7 is formed in the upper center of the liquefied gas absorbent material 2 .
The depth of this vertical hole 8 is at least such that the open end 7a of the gas conduit 7 is located with a required space between it and the bottom surface 8a of the vertical hole 8, and the gas conduit 7 is inserted into this vertical hole 8. It is housed with space around it.

In a liquefied gas cylinder with such a structure, most of the liquefied gas filled inside is impregnated with the liquefied gas absorbing material, so compared to the case where the same amount of liquefied gas is filled without the liquefied gas absorbing material 2. Therefore, even if the liquefied gas is filled to some extent excessively, the liquid level A will not become that high due to the water retention properties of the liquefied gas absorbing material 2. Even if liquefied gas seeps into the vertical hole 8 and accumulates in the space, the liquid level A of the liquefied gas will never reach the open end 7a of the gas conduit 7.

Furthermore, even when the cylinder body 1 is turned upside down, the liquefied gas in the vertical hole flows through the hole wall due to the inclination, so that the liquefied gas does not flow in from the opening end 7a, and the cylinder body 1 is turned upside down as shown in FIG. Then, the amount of water that cannot be retained by the lower liquefied gas absorbing material 2 leaks into the vertical hole 8 as excess liquefied gas, so the liquid level A is below the opening end 7a, and the liquid level A is below the opening end 7a.
is above the liquid level A in the vertical hole 8.

Therefore, the liquefied gas is in a liquid state at the opening end 7a.
It is more difficult for the gas to flow into the gas conduit 7, and the liquefied gas that flows into the open end 7a is always limited to gaseous gas.

(Effects of the invention) As mentioned above, this invention has a valve device 4 provided in the mountain cap 3 of the cylinder body 1.
A gas conduit 7 of a required length is connected to the lower side, and the open end 7a of the gas conduit 7 is connected to the bottom surface 8 at the center of the upper part of the liquefied gas absorbent 2 filled in the cylinder body 1.
A vertical hole 8 of a depth is formed between the liquefied gas cylinder and the liquefied gas cylinder. By making it possible to always supply liquefied gas in gaseous form, the supply of liquefied gas to burner devices and gas combustors is stabilized, and abnormal combustion or incomplete combustion due to excessive gas supply is prevented. be able to.

In addition, it is only necessary to connect a gas pipe to the valve device and provide a vertical hole in the liquefied gas absorbing material to accommodate the gas pipe, so the structure is simple, there are no failures, and no special operations are required during use. It has the following advantages.
