Description

엘피지 용기용 밸브{VALVE FOR LPG CYLINDER}Valve for LPG container {VALVE FOR LPG CYLINDER}

본 발명은 조정기 또는 충전기가 체결되지 않은 상태일 때 가스통로를 밀폐하여 엘피지 용기에 저장된 가스가 유출되는 것을 방지하는 엘피지 용기용 밸브에 관한 것이다. The present invention relates to a valve for an LPG container to prevent leakage of gas stored in the LPG container by sealing a gas passage when a regulator or a charger is not fastened.

현재, 엘피지 용기에는 엘피지 용기에 저장된 가스의 출입 및 안정성을 부여하는 밸브 어셈블리가 장착된다. 밸브 어셈블리의 가스 통로에는 조정기 또는 충전기가 체결되지 않을 상태일 때 가스 통로를 밀폐하여 엘피지 용기에 저장된 가스가 유출되는 것을 방지하는 밸브가 장착된다. Currently, the LPG container is equipped with a valve assembly that provides stability and entry of gas stored in the LPG container. The gas passage of the valve assembly is equipped with a valve that seals the gas passage when the regulator or the charger is not fastened to prevent the gas stored in the LPG container from leaking out.

종래의 엘피지 용기용 밸브 조립체는 공개특허공보 10-2010-0068118(2010년06월22일)에 개시된 바와 같이, 밸브본체와, 밸브본체에 나사 결합되고 통공된 가이드 공이 형성되는 고정부재와, 고정부재에 형성된 가이드 공에 삽입되어 이동되고 가이드 돌부가 형성되는 유로개폐부와, 유로 개폐부의 안착홈에 삽입되는 밀폐 스프링으로 구성된다.Conventional valve assembly for an LPG container, as disclosed in Patent Publication 10-2010-0068118 (June 22, 2010), a valve body, a fixing member screwed to the valve body and formed with a through hole, and fixed It is composed of a flow path opening and closing portion inserted into the guide ball formed in the member and moved to form a guide protrusion, and a sealing spring inserted into the seating groove of the flow path opening and closing portion.

이와 같은 종래의 밸브 조립체는 유로 개폐부가 후퇴되어 유로가 개방될 때 밀폐 스프링이 압축되는데, 이때 유로 개폐부가 미는 힘에 의해 밀폐 스프링이 압축되고 유로 개폐부는 압축된 밀폐 스프링에 의해 지지된 상태이므로 밀폐 스프링에 부하가 증가되고 이에 따라 밀폐 스프링이 변형되는 문제가 있다.In such a conventional valve assembly, when the flow path is retracted and the flow path is opened, the sealing spring is compressed. At this time, the sealing spring is compressed by the pushing force of the flow path opening and closing part, and the flow path opening is in a state supported by the compressed sealing spring. There is a problem in that the load on the spring is increased and the sealing spring is deformed accordingly.

또한, 밀폐 스프링이 완전히 압축될 경우 가스가 밀폐 스프링의 틈새로 통과해야되는데, 밀폐 스프링이 완전히 압축되면 밀폐 스프링에 틈새가 없어 가스의 흐름이 원활하게 이루어지지 못하는 문제가 있다. In addition, when the sealing spring is completely compressed, gas has to pass through the gap of the sealing spring. When the sealing spring is completely compressed, there is a problem in that there is no gap in the sealing spring, so that the gas cannot flow smoothly.

The gas passage 12 is sealed to prevent the gas stored in the LPG container from leaking out.

이러한 상태에서 도 4에 도시된 바와 같이, 가스 조정기 또는 충전기(100)가 가스 출입구(14)에 삽입되면 밸브부재(34)가 후퇴되면서 가스통로(12)를 개방한다. 그리고 밸브부재(34)의 헤드부(62)가 스톱퍼(38)의 걸림 돌기부(72)에 접촉되어 밸브부재(34)가 안정적으로 후퇴된 상태가 지지되고, 스프링(36)은 최대로 압축되지 않아 스프링(36)이 변형되는 것을 방지함과 아울러 스프링(36) 사이에 틈새가 형성되어 이 틈새로 가스가 원활하게 통과하게 된다. 일예로, 가스 출입구(14)에 충전기(100)가 장착될 경우 가스는 충전기를 통해 밸브 하우징(32)의 챔버부(78)로 유입되고, 챔버부(78)로 유입된 가스는 스톱퍼(38)의 유로부(76)를 통과하고 스프링(36)의 틈새를 통과하여 밸브바디(10)의 가스통로(12)로 유입되고 LPG 용기로 공급된다. In this state, as shown in FIG. 4, when the gas regulator or charger 100 is inserted into the gas inlet 14, the valve member 34 is retracted and the gas passage 12 is opened. And the head portion 62 of the valve member 34 is in contact with the locking projection 72 of the stopper 38 to support the state in which the valve member 34 is stably retracted, and the spring 36 is not compressed to the maximum. This prevents the spring 36 from being deformed, and a gap is formed between the springs 36 so that the gas passes smoothly through the gap. For example, when the charger 100 is mounted at the gas inlet 14, gas is introduced into the chamber unit 78 of the valve housing 32 through the charger, and the gas introduced into the chamber unit 78 is a stopper 38 ) Passes through the flow path portion 76 of the spring 36, flows into the gas passage 12 of the valve body 10, and is supplied to the LPG container.
