Description

파열형 햇치(Hatch)Ruptured Hatch

제1도는 본 고안의 실시예를 표시하는 평면도.1 is a plan view showing an embodiment of the present invention.

제2도는 제1도의 (A)-(A)선 단면도.2 is a cross-sectional view taken along the line (A)-(A) of FIG.

제3도는 제1도의 (B)-(B)선 단면도.3 is a cross-sectional view taken along the line (B)-(B) of FIG.

본 고안은 연료탱크내의 압력이 불규칙하게 높아질 때에 안전목적을 위하여 그 탱크내에 발생된 높은 압력을 급속히 해제시키기 위한 파열형 햇치에 관한 것이다.The present invention relates to a bursting hat for rapidly releasing the high pressure generated in the tank for safety purposes when the pressure in the fuel tank becomes irregularly high.

종래에 있어 탱크의 내부 압력이 급격하게 상승되어 위험 수준에 도달하기 전에 급속히 덮개가 비산되도록 하여 위험을 면하도록 한 파열형 햇치로서는, 구면형 경판(鏡板)의 볼록부를 하향하게 해서 그 경판의 외주부를 햇치 주연부의 내주면에 연속적으로 전둘레를 용접하는 것에 의해 내부 압력 상승에 의하여 경판의 볼록부가 상향되도록 역전되었을 때 주연부의 용접부가 파열되어서 경판이 파손비산되도록 한 것이었다.Conventionally, as a bursting hatch in which the inner pressure of the tank rises rapidly and the cover is rapidly scattered before reaching the danger level, thereby avoiding the danger, the convex part of the spherical hard plate is lowered and the outer peripheral part of the hard plate is lowered. By welding the entire circumference to the inner circumferential surface of the hat periphery continuously, when the convex portion of the hard plate was reversed by the internal pressure rise, the welded part of the periphery ruptured, causing the hard plate to break apart.

그 일예로 일본국 실용신안출원 소화 53-147271호에 개시된 파열형 햇치는 원통형의 주연부의 내표면에 전체의 외주부가 용접되며 하향으로 볼록하게 된 볼록부를 보유하는 얇은 구면형 경판으로 이루어져 있으며, 이러한 구조의 경판이 높은 압력을 받으면 처음에 하향의 볼록부가 상향으로 볼록하게 되는 것에 의해서 그 경판과 주연부 사이를 용접한 용접부가 변형되어져서 결국에는 파열되어 진다.For example, the bursting hat disclosed in Japanese Utility Model Application No. 53-147271 consists of a thin spherical hard plate having a convex portion that is welded to the outer periphery of the entire outer periphery and has a convex portion that is downwardly convex. When the hard plate of the structure is subjected to high pressure, the downwardly convex portion is first convex upward, thereby deforming the weld welded between the light plate and the periphery and eventually rupturing.

그 결과 구면형 경판은 압력을 방출키 위하여 주연부로부터 떨어지는 것이다.The result is that the spherical hardboard falls off the periphery to release the pressure.

그러나, 상기한 인용문헌에 개시된 파열형 햇치에 있어서는 굽힘 응력이 연속적으로 전체가 용접된 용접부의 전길이에 걸쳐서 균일하게 작용되므로 만약 얇은 구면형 경판이 높은 압력을 받아서 그 경판의 중앙부분이 상향으로 볼록하게 되더라도 용접부와 그 판의 외주부는 처음 용접상태로 그대로 남아있게 되는바, 높은 압력으로부터의 위험을 면할길이 없는 것이다.However, in the bursting hatch disclosed in the above cited reference, the bending stress acts uniformly over the entire length of the welded welded portion continuously, so that if the thin spherical plate is subjected to high pressure, the central portion of the plate is upward. Even if it is convex, the weld and the outer periphery of the plate remain in the initial welding state, there is no way to escape the danger from high pressure.

즉, 상기한 바와 같은 구조로서는 경판의 두께가 얇기 때문에 볼록부를 포함하는 중심부만이 역전되더라도 용접된 주면은 굽힘응력이 균등하게 작용되기 때문에 용이하게 역전되어서 파손되지 않게 된다고 하는 폐단점이 있는 것이다.That is, as the above-described structure, since the thickness of the hard plate is thin, even if only the center portion including the convex portion is reversed, the welded main surface is easily reversed and is not damaged because the bending stress is applied equally.

본 고안은 상기한 바와 같은 종래에 있어서, 폐단점을 해소키 위하여 안출한 것으로, 경판전체가 확실하게 역전 파열되어서 비산되도록 한 파열형 햇치를 제공하려는 것이다.The present invention has been made in order to solve the closed point in the prior art as described above, and is intended to provide a burst hatch in which the entire hard plate is reliably reversed and scattered.

이하 첨부된 도면에 의거 본 고안을 구체적으로 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 고안은, 구면형상의 경판(4)의 볼록부를 하향토록하여서 그 외주를 원통형 햇치(2)의 주연부(3)의 내주에 용접하여 이루어진 파열형 햇치에 있어서, 상기한 경판(4)의 외주를 원통형 햇치(2)의 주연부(3)의 내주면에 대하여서 원주방향으로 등간격마다 불연속으로 용접하고, 용접되지 않은 부분에 있어서 경판(4)과 햇치주연부(3)와의 사이를 밀봉제로서 밀봉하여 구성한 것이다.The invention devises a convex portion of the spherical hard plate 4 which is downwardly oriented so that its outer circumference is welded to the inner circumference of the periphery 3 of the cylindrical hatch 2. Is welded discontinuously at regular intervals in the circumferential direction with respect to the inner circumferential surface of the peripheral portion 3 of the cylindrical hatch 2, and seals between the hard plate 4 and the hatch peripheral portion 3 as a sealant in the unwelded portion. It is made up.

도면중 미설명부호인(1)은 석유탱크의 덱크(Deck)를, (5)는 주연부(3)와 경판(4)의 외주부를 용접한 용접부를 각각 표시하며, 이 용접부(5)의 총 길이는 경판(4)의 전체원주길이의 10%-25% 정도가 적당하고 또한 이 용접부(5)는 일정한 간격을 두고서 경판(4)에 작용하는 통상적인 변동압력(0.14-0.07kg/cm2)에 견딜 수 있는 정도로서 약하게 용접시켜 놓는다.In the drawing, reference numeral 1 denotes a deck of the oil tank, and 5 denotes a weld welded to the periphery 3 and the outer periphery of the hard plate 4, respectively. The length is preferably about 10% to 25% of the total circumference of the plate 4, and the welded portion 5 has a normal fluctuation pressure (0.14-0.07 kg / cm 2 ) acting on the plate 4 at regular intervals. Weak enough to withstand).

한편, 상기한 용접부(5)와 용접부(5)사이의 경판(4)과 햇치 주연부(3)와의 사이를 밀봉하는 밀봉제(6)로서는 내수성, 내후(耐候)성, 내 오존성 및 내열성등에 우수한 실리콘 고무등을 사용한다.On the other hand, the sealant 6 for sealing between the hard plate 4 between the welded portion 5 and the welded portion 5 and the hatch peripheral portion 3 is excellent in water resistance, weather resistance, ozone resistance and heat resistance. Silicone rubber is used.

본 고안은 이상과 같은 구성으로 인하여, 탱크 내부 압력이 상승하여 경판(4)을 역전시키도록 하는 소정의 압력에 도달하면 밀봉제(6)로서 밀봉된 밀봉부는 볼록부의 역전에 따라서 역전하려하므로, 용접부(5)에는 주위전체를 용접하였을 경우에 비하여 단위 길이당 큰 굽힘하중이 집중하여 작용하기 때문에 단번에 파열되어서 그 경판(4)은 비산되어 버린다.The present invention, due to the above configuration, when the pressure inside the tank rises to reach a predetermined pressure for reversing the hard plate 4, the sealing portion sealed with the sealant 6 tries to reverse according to the reversal of the convex portion, Since the large bending load per unit length concentrates on the welded part 5 compared with the case where the whole periphery is welded, it ruptures at once and the hard board 4 is scattered.

이처럼 본 고안의 파열형 햇치에 의하면 볼록부를 하향으로 해서 햇치의 주연 내부에 부착된 구면형의 경판은, 햇치 주연부와 원주방향으로 등간격으로서 봉연속으로 용접되어 있으므로, 탱크 내부압력 상승에 의하여, 경판의 볼록부가 역전되면 주변에 생기는 인장응력이, 그 용접부로 각각 집중하여 확실하게 파단되어서 경판이 비산되도록 하여 높은 압력으로부터의 위험을 미연에 방지할 수가 있는 것이다.Thus, according to the burst type hatch of the present invention, since the spherical hard plate attached to the inner periphery of the hat with the convex portion downward is welded at the rod periphery at equal intervals in the circumferential direction with the hat periphery, When the convex portion of the hard plate is reversed, the tensile stress generated in the periphery is concentrated and ruptured reliably, respectively, to the weld so that the hard plate can be scattered, thereby preventing the danger from high pressure.

또한, 구조도 간단할 뿐만 아니라, 밀봉제는 필요에 따라서 교환할 수가 있으므로 제작비가 싸며, 유지관리도 비교적 적게 소요된다는 우수한 효과를 보유하고 있는 것이다.In addition, the structure is simple, and since the sealant can be replaced as necessary, the manufacturing cost is low and the maintenance is also relatively low.
