휴대용 가스용기의 안전밸브{Safety relief valve for portable gas container}Safety relief valve for portable gas container

본 발명은 휴대용 가스용기의 안전밸브에 관한 것으로, 보다 상세하게는, 부탄가스 캔과 같은 휴대용 가스용기에 외부의 온도상승으로 인해 가스용기 내의 압력이 과도하게 높아지는 경우 밸브스템과 별도로 설치한 안전밸브를 통해 가스용기 내의 과압가스를 외부로 분출시켜 가스용기가 폭발하는 것을 방지하도록 한 휴대용 가스용기의 안전밸브에 관한 것이다.
The present invention relates to a safety valve for a portable gas container, and more particularly, a safety valve provided separately from the valve stem when the pressure in the gas container becomes excessively high due to an external temperature rise in the portable gas container such as a butane gas can. It relates to a safety valve of a portable gas container to eject the overpressure gas in the gas container to the outside through to prevent the gas container from exploding.

일반적으로 휴대용 가스용기는 액화 석유가스 중 부탄가스를 주원료로 한 부탄가스 혼합물을 충전하여 휴대용 가스렌지에 사용되는 휴대용 부탄가스 용기와, 액화 석유가스 등을 추진제로 사용하는 헤어스프레이, 살충제, 락카스프레이 등 에어로졸 용기를 들 수 있으며, 이러한 휴대용 가스용기는 용기 내의 가스압을 이용하여 내용물을 외부로 분출시키는 것으로, 내용물이 충전되어 있을 경우에는 용기 내에 일정 이상의 압력이 항상 작용하고 있다.
In general, portable gas containers are filled with a butane gas mixture composed mainly of butane gas from liquefied petroleum gas. And aerosol containers. Such a portable gas container ejects the contents to the outside by using the gas pressure in the container. When the contents are filled, a predetermined pressure or more is always acting in the container.

부탄가스 용기는 유통과정이나 사용 중에 주위에서 높은 열을 받게 되면 부탄가스 용기 내부에 들어 있는 액화가스의 압력이 상승하여 폭발하게 되는데, 특히 휴대용 가스렌지에 사용되는 부탄가스 용기의 경우 사용중 안전수칙을 지키지 않고 변칙적으로 사용하거나 고온 또는 일정 이상의 압력이 작용하여 내부 압력이 높아지게 되면 용기가 변형되거나 파손되고 심할 경우 폭발할 수 있다. 그러므로 휴대용 가스용기(캔)가 견딜 수 있는 압력과 변형 및 파열되는 압력에 대하여 법으로 규정하고 있다.
Butane gas can be exploded due to the increased pressure of the liquefied gas inside the butane gas container. If the internal pressure is increased due to anomalous use or high temperature or a certain pressure is applied, the container may deform or break and may explode if severe. Therefore, the law stipulates the pressure that the portable gas container (can) can withstand and the pressure at which deformation and bursting occur.

이와 같은 휴대용 가스용기의 안전을 위하여 일정 이상의 압력에서 작동하여 용기내 과압가스를 배출시키는 안전밸브에 대하여 몇 가지 기술이 출현하였는데, 그 중에서 본 발명의 출원인이 개발하여 등록받은 특허 제914620호 "휴대용 가스용기의 안전밸브"인데, 도 1을 참조하여 간략히 설명하면, 마운팅컵(1) 중앙에 위치하는 밸브스템하우징(2)의 측면에 고압가스 배출홀(4)이 형성된 부위에 별도의 안전밸브하우징(3)을 설치하고, 안전밸브하우징 내에 단면(斷面)이 T자 형상이고 수평부가 고압가스 배출홀의 상부에 위치하며, 수직부가 고압가스 배출홀을 관통하여 가스용기 내에 위치하게 되는 샤프트(5)와, 샤프트의 수평부와 고압가스 배출홀이 형성된 마운팅컵의 상부 사이에 끼워지는 가스켓(6)와, 샤프트의 수직부 하단(下端)에 결합되는 받침부재(7)와, 샤프트에 끼워져서 받침부재의 상부와 고압가스 배출홀이 형성된 마운팅컵의 하부 사이에 위치하게 되는 스프링(8)을 구비하여 구성되는 휴대용 가스용기의 안전밸브이다.
For the safety of such a portable gas container several technologies have appeared for the safety valve to operate at a certain pressure or more to discharge the overpressure gas in the container, among which patent No. 914620 "Portable" developed and registered by the applicant of the present invention Safety valve of the gas container ", briefly described with reference to FIG. 1, a separate safety valve in a portion where the high-pressure gas discharge hole (4) is formed on the side of the valve stem housing (2) located in the center of the mounting cup (1) A shaft having a housing (3), having a T-shaped cross section in the safety valve housing, a horizontal portion positioned above the high pressure gas discharge hole, and a vertical portion penetrating the high pressure gas discharge hole and positioned in the gas container ( 5), a gasket 6 fitted between the horizontal portion of the shaft and the upper portion of the mounting cup where the high-pressure gas discharge hole is formed, and a support member coupled to the lower end of the vertical portion of the shaft ( 7) and a spring (8) fitted to the shaft and positioned between the upper portion of the support member and the lower portion of the mounting cup where the high-pressure gas discharge hole is formed.
