Abstract

The present invention relates to a spiral gasket which is wound in many layers while alternating a metal thin plate and a soft filler with a thickness ratio of 2:1. The present invention provides a gasket with an unchanged form even for strong fastening force of a flange. The spiral gasket according to the present invention is fitted to a flange for connecting a pipe to a pipe and connecting a pipe and another mechanical portion to improve sealing of the flange. The spiral gasket is made by alternately winding a thin metal plate and a soft filler with a thickness ratio of 2:1 in many layers.

Description

고온·고압용 나선형 가스켓 {SPIRAL WOUND GASKET FOR HIGH TEMPERATURE AND HIGH PRESSURE FLUID}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a spiral gasket for high temperature and high pressure,

본 발명은 플랜지 사이에 삽입되는 가스켓에 관한 것이다.The present invention relates to a gasket inserted between flanges.

관과 관, 관과 다른 기계 부분을 연결할 때 쓰이는 부품을 플랜지(Flange)라고 한다. 플랜지는 금속 면을 맞대고 볼트와 너트로 결합되는데 플랜지 사이에 가스켓을 끼워서 결합하면 내부로 흐르는 유체나 기체가 결합 부위의 틈으로 새어나오는 정도를 낮출 수 있고 이를 실링(Sealing) 효과라고 한다.Parts used to connect pipes, pipes, and other parts of machinery are called flanges. The flange is connected to the metal surface by bolts and nuts. When the gasket is inserted between the flanges, the fluid or gas flowing into the flange can be lowered to the gap of the joint, which is called a sealing effect.

가스켓은 관을 통해 흐르는 유체나 기체의 특성에 따라 그 종류도 다양한데, 고온·고압의 유체나 기체가 흐를 경우 금속 재질의 가스켓을 사용하여 플랜지의 볼트와 너트를 한층 강하게 조여주는 것이 보통이다. 볼트와 너트의 강한 조임으로 가스켓에 무리한 힘이 가해지면 가스켓의 형태가 변형되어 그 기능을 다하지 못할 수 있다. 이에 대하여 금속박판을 나선형으로 감아 외부 힘에 강인한 형태를 만들면서 금속박판이 감긴 면에 소프트필러(예: 흑연, PTFE, 세라믹 등)를 감아서 탄성력과 복원력을 높이는 것이 하나의 해결책이 될 수 있다. 더불어, 금속박판을 얼마의 두께가 되도록 감는 것이 최적인지 알아보는 것은 의미있는 일이다.Gaskets are also available in a variety of types depending on the characteristics of the fluid or gas flowing through the pipe. When high-temperature, high-pressure fluid or gas flows, it is common to tighten the flange bolts and nuts more strongly using metal gaskets. If excessive force is applied to the gasket by strong tightening of the bolt and nut, the shape of the gasket may be deformed and the function may not be performed. On the other hand, a solution is to increase the elasticity and the restoring force by winding soft foil (eg, graphite, PTFE, ceramic, etc.) on the surface of the thin metal foil while making a strong form against the external force by spirally winding the thin metal foil . In addition, it is meaningful to find out how thin the metal sheet is best to wind.

본 발명이 이루고자 하는 기술적 과제는 플랜지의 강한 체결력에도 형태가 변하지 않는 가스켓을 제공하는 것이다.SUMMARY OF THE INVENTION It is an object of the present invention to provide a gasket in which the shape of the flange does not change even with a strong clamping force.

상기 기술적 과제를 달성하기 위하여, 본 발명의 일 형태에 따른 가스켓은 금속박판; 및 소프트필러;를 포함한다.According to an aspect of the present invention, there is provided a gasket comprising: a metal thin plate; And a soft filler.

상기 금속박판은 스테인리스(Stainless steel)를 대표적으로 이용한다.The metal thin plate is typically made of stainless steel.

상기 금속박판은 "V" 형태의 단면을 가지고 나선형으로 겹겹이 감을 수 있다.The metal foil may have a "V" shaped cross section and may be spirally wound in layers.

상기 소프트필러는 흑연, PTFE, 세라믹, 무기질 재질 중의 하나로 이루어진다.The soft filler may be one of graphite, PTFE, ceramics, and an inorganic material.

상기 금속박판과 상기 소프트필러는 서로 번갈아 가면서 겹겹이 감긴다.The metal foil and the soft pillar are alternately wound in layers.

상기 금속박판과 상기 소프트필러의 두께 비율은 2:1을 유지한다.The thickness ratio of the metal foil to the soft pillar is maintained at 2: 1.

본 발명의 실시례에 따르면 외부 힘에 대한 금속박판의 내구성과 소프트필러재의 복원력이 물리적으로 조화되어 플랜지의 볼트와 너트를 강하게 조이더라도 가스켓의 형태를 유지시킬 수 있다.According to the embodiment of the present invention, the durability of the thin metal plate against the external force and the restoring force of the soft pillar material are physically matched, so that the shape of the gasket can be maintained even if the bolt and nut of the flange are strongly tightened.

도 1은 본 발명의 실시례에 따른 가스켓의 사시도이다.
도 2는 본 발명의 실시례에 따른 가스켓의 부분 단면도이다.1 is a perspective view of a gasket according to an embodiment of the present invention.

이하에서 본 발명의 실시례를 첨부된 도면을 참고로 설명한다.Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

본 발명은 도 1에 도시한 바와 같이 금속박판(100)이 나선형으로 감긴 외형을 가진다.As shown in FIG. 1, the present invention has an outer shape in which the thin metal plate 100 is spirally wound.

본 발명은 도 2에 도시한 바와 같이 "V" 형태의 단면을 가진 금속박판(100); 및 금속박판(100)과 번갈아 가면서 감기는 소프트필러(200);를 포함한다.The present invention relates to a thin metal plate (100) having a cross section of the "V" shape as shown in Fig. And a soft pillar 200 wound alternately with the thin metal plate 100.

본 발명은 도 2에 도시한 바와 같이 금속박판(100)과 소프트필러(200)의 두께 비율을 2:1로 유지한다(예: 1mm 두께의 금속박판과 0.5mm 두께의 소프트필러).2, the thickness ratio of the metal foil 100 to the soft pillar 200 is maintained at 2: 1 as shown in Fig. 2 (for example, a thin metal plate with a thickness of 1 mm and a soft pillar with a thickness of 0.5 mm).
