Description

재충전용 부탄가스통 {A REFILLED TYPE BUTANE GAS CASK}Rechargeable Butane Gas Cylinder {A REFILLED TYPE BUTANE GAS CASK}

본 고안은 휴대용 가스 버너의 연료로서 많이 이용되는 재충전용 부탄가스통에 관한 것으로, 특히 가스의 방출과 충전시의 가스유통경로가 다르게 구성하여 충전시에는 오-링의 마모가 발생하지 않도록 함으로써 재충전용 부탄가스통의 사용연한을 연장시킬 수 있도록 한 것이다.The present invention relates to a rechargeable butane gas cylinder which is widely used as a fuel of a portable gas burner. In particular, the gas flow path at the time of discharge and filling of gas is configured differently so that the wear of the O-ring does not occur during charging. It is to extend the service life of butane gas cylinder.

우리가 일상 생활을 살아가면서 자원을 이용하여 생활에 필요한 물품을 생산하여 생활의 불편을 해소하고 있으나, 또 다른 이면에는 생산되어 사용한 물품들의 폐기에 따른 환경 오염과 그 처리 비용 및 자원의 고갈 현상이 발생하게 되므로서, 이를 해소할 수 있도록 다양한 형태의 재활용 기술이 제공되고 있다.In our daily lives, we use the resources to produce the necessary goods to solve the inconvenience of life, but on the other side, environmental pollution, disposal cost and resource depletion caused by the disposal of the produced and used goods are As it occurs, various forms of recycling technology are provided to solve this problem.

그러나, 아직 우리의 주변 환경에 있어 재활용 기술의 발전이 크게 선진화 되어 있지 않음에 따라 많은 자원과 그 처리 비용 및 시간이 소모되고 있다.However, as the development of recycling technology is not yet advanced in our surrounding environment, many resources, processing cost and time are consumed.

즉, 일례로 조작이 간편하여 누구나 쉽게 사용할 수 있도록 하는 등 그 사용상의 편의성을 제공하는 가열기구로서 야유회나 음식점 또는 가정집에서 많이 사용되는 휴대용 가스 버너의 주원료를 사용하도록 일정량의 부탄가스가 다 소모되면 가스통을 다시 재활용 하지 않고 바로 폐기 처분해야 했다.That is, for example, when a certain amount of butane gas is depleted to use the main raw material of a portable gas burner that is frequently used in a picnic, restaurant, or home, as a heating device that provides convenience for use, such as simple operation and easy use by anyone. The gas cylinders had to be disposed of immediately without being recycled again.

그러나, 상기와 같이 폐기 처분되는 가스통으로 인하여 환경오염이 발생되는 한편, 가스통의 제작에 따른 비용 부담과 더불어 가스통의 수거작업에 따른 처리 비용이 추가적으로 소모되는 등 효율적인 자원의 재활용 기회를 제공하지 못하는 불편함을 초래 하였다.However, due to the disposal of the gas cylinder as described above, environmental pollution occurs, while the inconvenience of not providing an efficient resource recycling opportunities, such as the cost burden of the production of the gas cylinder and the additional processing cost of the collection operation of the gas cylinder is consumed additionally. Caused.

이와 같은 문제점을 해소하기 위한 방안으로 근래에는 재충전이 가능한 휴대용 부탄가스통이 고안되어 사용되고 있는데, 종래의 재충전용 부탄가스통에 있어서는 가스방출용 밸브와 충전용 밸브를 가스용기의 몸체 상부와 하부에 각각 설치하거나 또는 가스용기 상부에 방출과 재충전이 동시에 가능한 가스밸브를 설치한 구조로 되어 있는바, 전자에 있어서는 부탄가스통의 구조가 복잡해지고 단가가 높아지게 되는 문제점이 있었고, 후자에 있어서는 가스의 방출과 재충전이 하나의 가스밸브에서 동일한 경로를 따라 이루어지게 됨으로써 가스밸브의 마모 특히, 주입노즐의 하부 외측에 형성된 오리피스를 막고 있는 오-링이 조기에 마모됨으로써 가스의 누출문제가 발생하거나, 이 오-링을 자주 교환해 주어야만 하는 문제점이 있었다.In order to solve such a problem, a portable butane gas cylinder which can be recharged has been devised and used in recent years. In the conventional butane gas butane gas cylinder, a gas discharge valve and a filling valve are installed on the upper and lower bodies of the gas container, respectively. In the former, there is a structure in which a gas valve capable of discharging and recharging at the top of the gas container is installed. However, the former has a problem that the structure of the butane gas cylinder becomes complicated and the unit price becomes high. By following the same path in one gas valve, wear of the gas valve may occur due to premature wear of the gas valve, in particular, the o-ring blocking the orifice formed on the lower outside of the injection nozzle, or the gas leak problem. There was a problem that must be exchanged frequently.

따라서, 본 고안은 이와같은 문제점을 해결하기 위해 안출한 것으로서, 본 고안의 목적은 하나의 가스밸브에 의해 가스의 방출과 재충전이 이루어지도록 된 재충전용 부탄가스통에서 가스의 방출과 재충전시의 가스유통경로와 가스밸브의 작동이 별도로 이루어지도록 함으로써 소모부품인 오-링의 마모를 최소화 함으로써 재충전용 부탄가스통에서의 가스누출이 발생하지 않도록 함과 동시에 재충전용 부탄가스통의 사용연한을 연장시킬 수 있도록 하는데 있다.Therefore, the present invention has been devised to solve such a problem, and an object of the present invention is to discharge and recharge the gas in a rechargeable butane gas cylinder in which the gas is discharged and recharged by a single gas valve. By separately operating the path and the gas valve, the wear of the O-ring, which is a consumable part, is minimized, so that the gas leakage from the rechargeable butane gas cylinder does not occur and the service life of the rechargeable butane gas cylinder can be extended. have.

또, 상기 노즐캡(50)의 밸브설치부(54)외측에는 니들밸브(60)가 열린 경우 외부로부터 유입된 가스가 가스통내부로 충전되기 위한 충전구멍(56)이 형성되어 있다.In addition, when the needle valve 60 is opened, a filling hole 56 is formed outside the valve installation part 54 of the nozzle cap 50 to fill gas into the gas cylinder from the outside.

이와 같이 구성된 본 고안은 도 3에 도시한 바와 같이 가스의 방출시에는 주입노즐(30)이 눌려 오-링(39)에 의해 막혀있던 오리피스(34)가 열리면서 가스통(1) 내부의 가스가 외부로 방출되고, 가스의 재충전시에는 도 4에 도시된 바와 같이 도시생략된 충전장치에서 주입노즐(30)의 노즐구멍(32)에 가해지는 가스압력에 의해 주입노즐(30)하단의 노즐구멍(32)을 막고 있던 니들밸브(60)가 스프링(70)의 힘을 이기면서 개방되어 노즐캡(50)의 측부에 형성된 충전구멍(56)을 통해 가스통으로 충전되는 것이다.The present invention configured as described above has an orifice 34 which is blocked by the o-ring 39 by pressing the injection nozzle 30 when the gas is discharged as shown in FIG. When the gas is recharged, the nozzle hole at the bottom of the injection nozzle 30 is discharged by the gas pressure applied to the nozzle hole 32 of the injection nozzle 30 in the filling apparatus as shown in FIG. 4. The needle valve 60, which was blocking the 32, is opened while overcoming the force of the spring 70, and is filled with the gas cylinder through the filling hole 56 formed at the side of the nozzle cap 50.

이에 따라 본 고안의 재충전용 부탄가스통은 가스의 방출과 충전시 가스의 유통경로가 다르고 가스의 방출시에만 주입노즐이 눌리게 되므로 주입노즐의 오리피스를 막고 있는 오-링이 가스의 방출시에만 주입노즐과 슬라이드되면서 접촉하게 되므로 오-링의 마모가 최소화 되는 것이어서 가스의 재충전시에는 오-링이 마모되는 일이 없으므로 반복적인 가사의 방출과 충전시에도 오-링의 마모를 최소화 할 수 있으므로 재충전용 부탄가스통의 사용연하을 연장시킬 수 있게 되는 것이다.Accordingly, the rechargeable butane gas cylinder of the present invention has a different gas distribution path when the gas is discharged and charged, and the injection nozzle is pressed only when the gas is discharged. Therefore, the O-ring blocking the orifice of the injection nozzle is injected only when the gas is discharged. Since the contact with the nozzle slides to minimize the wear of the O-ring, and the refilling of the gas does not cause the O-ring to wear, so the wear of the O-ring can be minimized during repeated discharge and filling. It is possible to extend the service life of the molten butane gas cylinder.

이상 설명한 바와 같이 본 고안은 재충전이 가능한 부탄가스통의 가스밸브에서 가스의 충전시에는 니들밸브가 개방되어 충전이 이루어지고, 가스의 방출시에는 오-링에 의해 막혀 있던 오리피스가 개방되면서 가스의 방출이 이루어지도록 함 것으로, 본 고안에 의하면 그동안 자주 교환해주어야 했던 소모성부품인 오-링의 마모가 최소화 됨으로써 가스통의 사용연한을 최소 2배이상 연장시킬 수 있는 실용적인 효과를 갖는다.As described above, in the present invention, the needle valve is opened when the gas is filled in the gas valve of the rechargeable butane gas cylinder, and the gas is discharged while the orifice blocked by the O-ring is opened when the gas is discharged. In order to achieve this, the present invention has a practical effect of extending the service life of the gas cylinder by at least two times by minimizing the wear of the O-ring, which is a consumable part that has been frequently replaced.
