본 고안은 통상의 가스용기 밸브의 내부에 가스의 방지장치를 설치하는 것으로서, 특히, 가스용기에 가스를 재충진할 때 과유출방지장치가 없을때와 같이 원활하고 신속하게 할수 있는 가스재충진장치와 가스의 과유출로, 자동밸브가 가스의 흐름을 차단하였을 때 이를 떼어주는 별도의 장치를 설치하지 않고도 간단히 떼어줄수 있는 구조의 자동 밸브를 갖는 가스용기의 개폐장치에 관한 것이다.The present invention is to install a gas prevention device inside the gas container valve, in particular, gas refilling device that can be smoothly and quickly, such as when there is no overflow prevention device when refilling gas in the gas container With the overflow of the gas, the automatic valve relates to the opening and closing device of the gas container having an automatic valve of the structure that can be easily removed without installing a separate device for removing the flow of gas when it shuts off.

현재 가스의 수요가 급증하고 있으나 가스용기에 가스의과 유출방지를 위한 안전장치가 없어, 용기의 취급부주의 또는 자재 결함등으로 가스용기의 폭발사고가 빈번히 발생하고 있는바, 그 대책이 시급한 실정이다.The demand for gas is increasing rapidly, but there is no safety device to prevent the outflow of gas in the gas container, and the explosion of the gas container is frequently caused by inadvertent handling of the container or material defects, so the countermeasures are urgently needed.

가스용기의 폭발사고를 방지하기 위해서는 가스용기 밸브의 내부에 과유출방지장치를 설치하는 것이 가장 바람직한 방안이나, 용기밸브의 내부에 과유출방지장치를 설치할 경우, 가스용기에 가스를 재충진할때 과유출방지 장치가 장애가 되어 시간이 많이 걸리는 결함이 있고, 과유출현상이 발생하여 자동밸브가 가스의 흐름을 차단했을 때, 이를 밀어떼어주는 장치를 별도로 설치하여야 하는 문제점이 있어 실용화 되지 못하고 있는 실정이다.In order to prevent the explosion of the gas container, it is most preferable to install an overflow prevention device inside the gas container valve.However, when the overflow prevention device is installed inside the container valve, Overflow prevention device is a problem that takes a long time due to obstacles, and when the automatic valve shuts off the flow of gas due to the overflow phenomenon, there is a problem that it is necessary to install a separate device to push it apart. to be.

본 고안은 이와 같은 문제점을 완벽하게 해결하여 가스용기의 폭발사고를 예방토록 한 것으로 이하 첨부 도면에 따라 상세히 설명하면 다음과 같다.The present invention is to solve the problem completely to prevent the explosion accident of the gas container as described in detail below in accordance with the accompanying drawings.

제1도와 같이 내부가 관통되게 통공과 공실을 천공하여 가스유입구(2)와 가스배출구(3)를 형성하고, 상측에 개폐핸들(1)과 개폐밸브(4)를 연설유삽하고, 중간측방에 안전변(5)을 설치하여서된 공지의 가스용기밸브에 있어서, 가스용기 밸브 내부, 즉 가스유입구(2) 상측에, 내부가 관통되게 통공을 천공하고, 상측내부에 0링(7)을 유삽하고, 상부측방에 가스일정양통과공(8)을 천공하며, 하부측방에 가스재충진공(10)을 천공하고, 내부에 스프링(11)과 자동밸브(9)를 수용한 원통(6)을 나삽 하였다.As shown in FIG. 1, the gas inlet 2 and the gas outlet 3 are formed by drilling the through-hole and the vacancy through the inside, and opening / closing the opening / closing handle 1 and the valve 4 in the upper side. In the well-known gas container valve provided with the safety valve (5), a through hole is drilled through the inside of the gas container valve, that is, above the gas inlet (2), and an 0 ring (7) is inserted into the upper side. , The gas constant through hole (8) in the upper side, the gas refilling hole (10) in the lower side, and the cylinder (6) containing the spring (11) and the automatic valve (9) inside It was.

이와 같이 구성된 본 고안의 작용효과는 다음과 같다.Effects of the present invention configured as described above are as follows.

가스용기에 가스호스를 연결하여 가스를 사용할때는 제2도와 같이 가스일정양통과통(8)과, 원통(6)과 자동밸브(9)의 틈새로 흐르는 가스를 사용하게되는데, 이때 자동밸브(9)는 가스일정량통과공(8)과 가스재충진공(10)의 사이에 위치한 채로 움직이지 않는다. 그러나 허용유량, 즉 가스일정양통과공(8)과, 원통(6)과 자동밸브(9)의 틈색로 흐르는 가스의 양보다 많은 양이 흐를 때는 제2도와 같이 원통(6)의 밑구멍과 가스재충진공(10)을 통하여 원통(6) 내부로 가스가 흐르게 되어, 자동밸브(9)를 밀어 올리게 되어 자동밸브(9)가 0링(7)에 닿아 가스의 흐름을 차단하게 된다. 가스누설부분을 수리한후, 다스 가스를 사용할때는 개폐핸들(1)을 돌려 용기밸브를 잠겨주면 개폐밸브(4)의 밑변이 자동밸브(9)의 상측돌출부를 눌러주어 0링(7)에서 떼어주게 되는데, 다시 개폐핸들(1)을 서서히 돌려 용기밸브를 열어주면 가스호스에 가스가 없는 상태임의로, 순간적으로 많은 가스가 흐르게 되는데, 가스일정양통과공(8)과 가스재충진공(10) 및 원통(6) 밑구멍을 통하여 원통(6)내부로 가스가 흐르게 됨으로 가종밸브(9)는 다시 위로 밀려 올라가게 된다.When the gas is connected to the gas container and the gas is used, the gas flowing through the gap between the gas constant passage (8), the cylinder (6) and the automatic valve (9) is used as shown in FIG. 9) does not move while being located between the gas constant passing hole (8) and the gas refilling hole (10). However, when the flow rate is larger than the allowable flow rate, that is, the amount of gas flowing through the gas constant through hole 8 and the gap between the cylinder 6 and the automatic valve 9, the bottom hole and the gas of the cylinder 6 as shown in FIG. Gas flows into the cylinder 6 through the refilling cavity 10 and pushes up the automatic valve 9 so that the automatic valve 9 contacts the 0 ring 7 to block the flow of gas. After repairing the gas leakage part, turn the opening and closing handle (1) to lock the container valve when using gas, and the lower side of the opening / closing valve (4) presses the upper projection of the automatic valve (9), When you open the container valve by slowly turning the opening / closing handle (1) again, a lot of gas flows instantaneously because there is no gas in the gas hose. And the gas flows into the cylinder 6 through the bottom hole of the cylinder 6, and the seed valve 9 is pushed upward again.

그러나, 개폐핸들(1)을 완전히 연 상태가 아니므로 자동밸브(9)의 상측돌출부가 개폐밸브(4)의 밑변에 닿아 0링(7)에 달라붙지 못하여 가스의 흐름을 차단하지 못하며, 가스는 자동밸브(9)와 원통(6)의 틈새로 흘러들어가 순식간에 가스호스에 충만하게 되며, 아울러 가스의 흐름이 정지되어 가스압이 않음으로 자동밸브(9)는 자중에 의하여 밑으로 떨려져 정상시와 같이 위치하게 된다.However, since the opening / closing handle 1 is not completely open, the upper protrusion of the automatic valve 9 does not touch the bottom ring of the opening / closing valve 4 so that it does not stick to the 0 ring 7 and does not block the flow of gas. Flows into the gap between the automatic valve (9) and the cylinder (6) and fills the gas hose in an instant. Furthermore, since the flow of gas stops, the automatic valve (9) drops downward due to its own weight. It is located like a poem.

가스용기에 가스를 재충진할때는 제2도와 같이 강한 가스압으로 저동밸브(9)가 가스재충진공(10)밑으로 밀려 내려가게 되어 과유출방지장치가 없을대와 같이 신속하게 가스를 충진할 수 있게 되며, 가스충진 후에는 스프링(11)에 의하여 자동밸브(9)는 정상위치로 복귀되는 것이다.When gas is refilled into the gas container, the low-pressure valve 9 is pushed down under the gas refilling cavity 10 by the strong gas pressure as shown in FIG. 2 so that the gas can be filled quickly as there is no overflow prevention device. After the gas filling, the automatic valve 9 is returned to the normal position by the spring 11.

특히, 0링(7)에 달라붙은 자동밸브(9)를 밀어떼어주는 장치를 개폐밸브(4)의 밑변등에 설치할 경우 과유출방지장치 이후의 가스통로의 넓이를 좁아지게 하는 결과가 초래되는 데 이렇게 될 경우, 자동차단 성능에 영향을 줄 뿐아니라 잔 가스회수 및 가스재충진시에 장애가 되는 것이다.In particular, when the device for pushing off the automatic valve 9 attached to the 0 ring 7 is installed on the bottom side of the on-off valve 4, the result is that the width of the gas passage after the overflow prevention device is narrowed. This will not only affect the shut-off performance, but will also hinder the gas recovery and gas refill.

따라서 고안은 가스용기밸브의 내부에 과유출방지장치를 설치하여 가스사고를 예방하는데 지대한 효과를 제공케되는 실용적인 고안인 것이다.Therefore, the invention is a practical design that provides a great effect in preventing gas accident by installing an overflow prevention device inside the gas container valve.
