본 고안은 외부온도나 화학적 분해등에 의하여 기화팽창되는 물질(예컨데 휘발성액체, 연축전지의 전해액 황산등)을 담아 보관하거나 운반하는 밀폐용기내의 팽창압력을 소정치로 일정하게 유지시켜주는 안전밸브장치의 개량에 관한 것이다. 주지된 바와같이 외부의 온도나 화학적분해등에 의해 기화 팽창되는 물질을 담아 보관하거나 운반하는 밀폐용기에는 필히 그 안전장치로서 안전밸브를 장착하여 소정압력 이상으로 기화팽창되는 산무가스를 신속히 외부로 배출토록 하므로 과포화에 의한 용기의 파손과 폭발을 미연에 방지하였던 것은 널리 알려진 사실이었다.The present invention provides a safety valve device that maintains a constant expansion pressure in a sealed container that contains or evaporates materials (e.g. volatile liquid, sulfuric acid electrolyte of lead acid battery) by external temperature or chemical decomposition. It is about improvement. As is well known, a sealed container that stores or transports a substance which is vaporized and expanded by external temperature or chemical decomposition must be equipped with a safety valve as a safety device so as to quickly discharge the fugitive gas vaporized and expanded above a predetermined pressure to the outside. Therefore, it was well known that the vessel was prevented from being damaged or exploded by supersaturation.
그런데 상기한 안전밸브장치는 주로 비교적 복잡한 구조로 되어있어 생산가가 높아짐에 따라 대형용량의 용기등에는 적합하나 소형용기에는 경제적인 이유등에 의하여 실제 무시되어 왔었다. 이에 본출원인은 제1도와 같이 비교적 간단한 구조의 안전밸브를 개발하여 현재까지 사용하여 왔으나 이러한 종래 안전밸브에는 사용중 여러가지 결점이 발견되어 불가피 이를 보완개발하기에 이른 것으로 먼저 제1도의 종래 안전밸브를 첨부도면에 의거 설명하면 다음과 같다.By the way, the safety valve device has a relatively complex structure is mainly suitable for large-capacity containers, etc. as the production price increases, but has been practically ignored for economic reasons for small containers. Therefore, the present applicant has developed a safety valve with a relatively simple structure as shown in FIG. 1, and has been using it until now. However, the conventional safety valve has been found to have various defects in use. Referring to the drawings as follows.
즉 밸브체(1)의 주벽에 평면상의 배기공(2)을 천공하고 그 배기공(2)상면이 덮어지도록 탄성이 양호하고 비교적 넓은폭의 원통형 고무밴드(3)를 복착하여서 된것인데, 이는 배기공(2)의 외연이 평면상으로 되어있기 때문에 밸브체(1)의 외주면이 매끈하고 원통형 고무밴드(3)의 탄성이 양호할 때는 비교적 용기내의 팽창압력에 의한 작동이 원활하나 원통형 고무밴드(3)가 노화되어 약간이라도 느슨하여지거나 제작시 밸브체(1)의 외주면이 매끈하지 못할때에는 그 밀폐성이 양호치 못하여 밀폐용기내의 소정압력 이하에서도 쉽게 고무밴드(3)와 밸브체(1)의 주벽간극 사이로 산무가스가 누설되어 용기내의 소정압력을 유지치 못할뿐 아니라 용기내의 수장된 기화물질의 과다배출로 인한 손실 또한 막대하였고 특히 이를 방지키 위하여 자주 원통형 고무밴드(3)를 교체해야하는 번거로움과 밸브체(1)의외 주면을 매끈하게 하기위한 제조상의 문제 및 이로인한 제품의 불량이 많아짐에 따라 생산가가 높아지는 등의 비경제적인 요인을 배제할 수가 있었다. 본 고안은 상기한 종래의 제반문제점을 감안하여 극히 간단한 구조로서 높은 성능의 안전밸브 장치를 제공코저 안출된 것으로 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.That is, it is made by drilling a planar exhaust hole 2 on the circumferential wall of the valve body 1 and attaching a cylindrical rubber band 3 of relatively wide elasticity so that the upper surface of the exhaust hole 2 is covered. Since the outer edge of the exhaust hole 2 is planar, when the outer circumferential surface of the valve body 1 is smooth and the elasticity of the cylindrical rubber band 3 is good, the operation is relatively smooth due to the expansion pressure in the container. When (3) ages and becomes slightly loose or the outer peripheral surface of the valve body 1 is not smooth at the time of manufacture, its sealing property is not good, and the rubber band 3 and the valve body 1 can be easily carried out even below the predetermined pressure in the sealed container. In addition to the leakage of acid fumes between the gaps between the main walls of the vessels, it was not possible to maintain the pressure in the vessel, as well as the loss due to the excessive discharge of stored vaporized substances in the vessel. 3) It was possible to eliminate the trouble of having to replace and manufacturing problems for smoothing the outer main surface of the valve body (1), and the uneconomic factors such as the increase in the production price due to the increase of the defective products. The present invention has been devised to provide a safety valve device having a high performance as an extremely simple structure in view of the above-mentioned conventional problems, which will be described in detail with reference to the accompanying drawings.
첨부도면중 제2도 내지 제4도에 있어서, 제1도와 동일한 구조는 동일부호가 부여하였다.2 to 4 in the accompanying drawings, the same reference numerals are given to the same structures as those in FIG.
즉 밸브체(1)의 외주면에 천공된 배기공(2)외주연에 비교적 선단이 뾰족하도록형의환턱(4)를 용출시키고, 그형의 환턱(4)에 의하여 팽팽하게 당겨지도록 원통형 고무밴드(3)를 복착시켜서 된 것이다.That is, the tip is relatively sharp at the outer circumference of the exhaust hole 2 perforated on the outer circumferential surface of the valve body 1. Eluting the round jaw (4) Cylindrical rubber band 3 is piled up so that it may be pulled tightly by round mold 4 of mold.
도면중 미설명부호 5는 밀폐용기이다.Reference numeral 5 in the drawings is a sealed container.
이와같이 구성된 본 고안은 밸브체(1)외주면의 배기공(2)외 주연에 비교적 선단이 뾰족하도록형의 환턱(4)이 용출되어 있어 제2도 및 제4도와 같이 그 상면에 복착된 원통형 고무밴드(3)가 상기환턱(4)에 팽팽하게 밀착되게 된다.The present invention configured as described above has a relatively sharp tip at the outer periphery of the exhaust hole (2) on the outer peripheral surface of the valve body (1). The mold round jaw 4 is eluted so that the cylindrical rubber band 3, which is coated on its upper surface as shown in FIGS. 2 and 4, is tightly attached to the round jaw 4.
이때 밀폐용기(5)내에 수용된 수용물질의 기화팽창 계수 및 밀폐용기(5)의 내구성에 따라형환턱(4)의 높이와 원통형 고무밴드(3)의 두께 및 그 탄성계수를 조절하여 설치하여야만 그 효율이 높아지게 되는 것이다.At this time, according to the vapor expansion coefficient of the receiving material contained in the sealed container (5) and the durability of the sealed container (5) The efficiency is increased only by installing the height of the ring jaw (4) and the thickness of the cylindrical rubber band (3) and its elastic modulus.
따라서 원통 형고무밴드(3)에서 배기공(2) 외주연의형 환턱(4)부위측이 매우 팽팽하게 밀착되어 있으므로 밀폐용기(5)내의 압력이 소정치 이하에서는 배기되는 일이 거의없고, 정확히 소정압력 이상에서만 배출되게 하여 항상 일정압력을 유지시킬 수 있으며 사용중 원통형 고무밴드(3)가 약간 노화되었거나 밸브체(1) 외주면이 매끈하지 않더라도 밀폐성을 긴밀히 유지하여 주기때문에 원통형 고무밴드(3)의 수명을 연장시킬 수 있고 제작시 밸브체(1)의 외주면에 대한 큰 정밀성은 요구하지 않으므로 생산가를 대폭인하시킬 수 있음과 동시에 밀폐용기(5)내의 불필요한 산무가스의 배출로 인한 경제적인 손실을 억제할 수 있는 것으로 특히 연축전지의 전조에 간편히 설치하여 사용하면 밀폐용기(5)내의 압력을 정확하게 조정치로 유지시켜 주므로 축전지의 성능을 크게 높히고 그 수명역시 길게 연장할 수 있는 다각적인 효과도 얻을 수 있다.Therefore, the outer periphery of the exhaust hole (2) in the cylindrical rubber band (3) Since the part of the annular jaw (4) is in close contact with each other very tightly, the pressure in the airtight container (5) is hardly exhausted at a predetermined value or less, and it can be discharged only at a predetermined pressure or more to maintain a constant pressure at all times. Even if the cylindrical rubber band 3 is slightly aged or the outer circumferential surface of the valve body 1 is not smooth, the sealing property is maintained closely so that the life of the cylindrical rubber band 3 can be extended and the outer circumferential surface of the valve body 1 can be Since it does not require large precision, it can significantly reduce the production cost and at the same time suppress economic losses due to the discharge of unnecessary fumes in the airtight container (5). By keeping the pressure in the container 5 accurately adjusted, the performance of the battery can be greatly improved and its life can be extended for a long time. There are also multiple effects.
