Description

이중 재질로 구성된 안전밸브{the safety valve which is composed of double quality of materials}The safety valve which is composed of double quality of materials}

본 고안은 내용적이 약 5L(리터) 이상이 되는 실린더 형상의 몸통 내부에 농약 및 영양제 등 농사용 분무액을 분사하기 위한 분무기 압력탱크에 압축 내용물을 고압으로 저장하기 위한 고압용기의 밸브장치에 관한 것이다.The present invention relates to a valve device of a high pressure vessel for storing compressed contents at a high pressure in a sprayer pressure tank for spraying agricultural spray liquids such as pesticides and nutrients into a cylindrical body having a volume of about 5 liter (liter) or more. .

일반적으로 농사용 분무기나 농약살포용 압축용기 혹은 고압을 발생하여 고압을 저장하는 저장용기나 소화 약제 등의 저장용기와 같이 기체 상태의 가스를 고압으로 저장시키기 위한 고압용기는 그 크기가 비교적 크게 되는 실린더 형상의 점보용기로 제조되며, 상기 고압용기의 상단 네크링(Neck-ring) 부분에는 용기의 내부에 저장된 고압가스를 필요에 따라 선택적으로 배출시키기 위한 밸브기구가 설치되어 있다.In general, high pressure containers for storing gaseous gases at high pressure, such as agricultural sprayers, compressed containers for pesticide spraying, or storage containers for generating high pressures or storage containers such as fire extinguishing agents, are cylinders of relatively large size. It is made of a jumbo container having a shape, and a valve mechanism for selectively discharging the high pressure gas stored inside the container is installed at the upper neck-ring portion of the high pressure container.

상기와 같이 고압용기에 설치되는 밸브기구의 대표적인 예로는, 고압용기의 내부공간과 연통 되는 가스 배출통로가 형성된 밸브 보디가 고압용기의 네크링 부분에 체결 식으로 고정 설치된 상태에서, 고압용기의 내부압력이 일정 수준 이상으로 상승하게 되면, 파열되거나 혹은 합성수지로 만든 고압용기인 경우에 합성수지재질의 팽창률과 다른 금속재질의 안전밸브를 삽입하였을 경우 재질에 따른 수축 및 팽창률로 인하여 용기의 압력이 발생 되었을 시 연결부분에서 압력공기가 새거나 내용물이 유출되는 사례가 빈번히 발생하였다. 또한, 충격을 받았을시 고압용기와 밸브의 이격 현상이 발생하여 미세한 균열 사이로 고압이 유출되는 사례가 발생하고 이로 인하여, 개폐 밸브의 수리나 유지보수 및 그 교체시 고압용기에 저장된 고압공기를 대부분 방출시킨 상태에서 해당 작업을 수행한 다음, 고압용기의 내부에 누출액을 다시 재충전시키는 방식이 주로 이루어짐에 따라, 개폐밸브의 수리나 유지보수 및 그 교체작업에 많은 시간과 비용이 소요되고, 가스방출에 따른 소음 및 안전사고의 위험성 또한 증가하게 될 뿐만 아니라, 고압용기의 사용에 따른 전체적인 경제성이 크게 저하되는 문제점이 있었다.As a representative example of the valve mechanism installed in the high-pressure container as described above, in the state in which the valve body formed with a gas discharge passage communicating with the internal space of the high-pressure container is fixedly installed on the necking portion of the high-pressure container, the inside of the high-pressure container When the pressure rises above a certain level, the pressure of the container may be generated due to the expansion rate of the resin material and the expansion and contraction rate of the other metal when the safety valve is inserted in the case of a high pressure container made of synthetic resin. Frequent cases of leaking pressure air or spilling of contents at the joints of the city occurred. In addition, when shock is received, high pressure vessels and valves are separated from each other and high pressure is leaked between the micro cracks. Therefore, most of the high pressure air stored in the high pressure vessels is released during repair, maintenance, and replacement of the valve. After the relevant work is performed in the above state, the method of refilling the leakage liquid inside the high pressure container is mainly performed. Therefore, it takes a lot of time and money to repair or maintain the valve and to replace the gas. In addition to increasing the risk of noise and safety accidents, there was a problem that the overall economic efficiency of the use of the high-pressure container is greatly reduced.

상기와 같은 구성으로 이루어진 본 고안의 작용으로 인하여 금속재질로 만들어진 안전밸브가 합성수지 고압용기에 설치되었을 시 재질에 따른 팽창과 수축률에 의하여 발생할 수 있는 압력유출에 대한 안전밸브로서의 문제점을 해소하여 충격이나 온도의 변화에도 본 고안의 제품을 설치하였을 시 압력유출이 없으면서 안전밸브의 역할을 다 할 수 있는 효과를 가진다.When the safety valve made of metal material is installed in the synthetic resin high pressure container due to the action of the present invention having the configuration as described above, to solve the problem as a safety valve for the pressure leakage caused by the expansion and contraction rate according to the material When the product of the present invention is installed even with the change of temperature, there is an effect that it can play the role of a safety valve without pressure leakage.
