Abstract

PURPOSE: A gasket for a flange pipe is provided to prevent an outflow of fluid running through a flange pipe by being transformed according to inner pressure of the flange pipe. CONSTITUTION: A gasket's circumference is established with plural bolt holes(12) for a bolt(6) connecting a flange pipe(5) to penetrate. A core(14) of a metallic material underlies in the inner side of the gasket(2) to prevent a transformation of the gasket(2). The core(14) comprising a ring-shaped disc like the gasket forms plural bolt holes(13) around a skirt and produces the gasket burying the core(14) by injecting a material of rubber quality into the core(14). Plural folds of protrusions(16) sticking to the end portion of the flange pipe(5) with pressure are formed around the circumferences of the high and lower side of the gasket(2). The protrusions(16) are annularly protruded on the circumference of the gasket(2) to be concentric with the gasket(2). After the gasket(2) is fixed on a connection part of the flange pipe, the flange pipe(5) is tied with a bolt(6). The end side of the flange pipe(5) presses the front and rear sides of the gasket(2) so that the protrusions(16) formed on the front and rear sides are pressed and transformed and attached to the end portion of the flange pipe(5). Therefore, the flange pipe(5) is mutually and tightly connected.

Description

플랜지관용 가스켓{gasket for flange}Gasket for flanges

본 발명은 플랜지관용 가스켓에 관한 것으로서, 보다 상세하게는 플랜지관 내부의 압력에 의해 변형되어 누수나 누출이 발생되는 것을 방지할 수 있도록 된 새로운 구조의 플랜지관용 가스켓에 관한 것이다.The present invention relates to a gasket for a flange pipe, and more particularly, to a flange pipe gasket having a new structure that can be prevented from leaking or leaking by being deformed by the pressure inside the flange pipe.

일반적으로, 상호 연결되는 플랜지관의 사이에는 플랜지관을 기밀하게 연결할 수 있도록 하는 가스켓이 구비된다. 이러한 플랜지관용 가스켓은 도 1에 도시한 바와 같이, 중앙에 통공(4)이 형성된 얇은 링형상의 디스크로 구성되는데, 그 표면에 작용되는 압력에 의해 탄성변형될 수 있는 고무재질로 구성되며, 그 표면은 별도의 돌출부가 형성되지 않고 평탄하게 구성된다.In general, a gasket is provided between the flange pipes to be connected to each other so that the flange pipe can be hermetically connected. This flange tube gasket is composed of a thin ring-shaped disk having a through-hole 4 in the center, as shown in Figure 1, consisting of a rubber material that can be elastically deformed by the pressure applied to its surface. The surface is flat without any separate protrusions.

따라서, 플랜지관(5)의 사이에 이 가스켓(2)을 배치하고, 플랜지관(5)을 볼트(6)로 상호 고정한 후, 상기 볼트(6)를 조이면, 플랜지관(5)이 가스켓(2)의 양면을 압착하여 가스켓(2)이 변형되면서, 플랜지관(5) 사이의 틈새를 막아 플랜지관(5)을 기밀하게 연결하게 된다.Therefore, when this gasket 2 is arrange | positioned between the flange pipes 5, the flange pipe 5 is mutually fixed with the bolt 6, and the said bolt 6 is tightened, the flange pipe 5 will be a gasket ( As the gasket 2 is deformed by compressing both sides of 2), the gap between the flange tubes 5 is prevented, thereby tightly connecting the flange tubes 5.

그런데, 이러한 플랜지관용 가스켓(2)은 비교적 변형이 자유로운 고무재질로 구성되므로, 플랜지관(5)의 내부에 높은 압력이 작용될 경우, 압력에 의해 가스켓(2)의 지름이 확대되면서, 그 외측이 플랜지관(5)의 연결부 외부로 밀려나가게 되며, 이에따라, 플랜지관(5)과 가스켓(2)사이에 틈이 발생되어, 플랜지관(5) 내부를 흐르는 유체가 이러한 틈을 통해 외부로 유출될 수 있는 문제점이 있었다.However, since the flange gasket 2 is made of a rubber material relatively free of deformation, when a high pressure is applied to the inside of the flange tube 5, the diameter of the gasket 2 is enlarged by the pressure, and the outside thereof. This is pushed out of the connecting portion of the flange pipe (5), accordingly, a gap is generated between the flange pipe (5) and the gasket (2), the fluid flowing inside the flange pipe (5) flows out through the gap There was a problem that could be.

본 발명은 상기의 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 플랜지관(5) 내부의 압력에 의해 변형되어, 플랜지관(5)을 따라 흐르는 유체가 외부로 유출되는 것을 방지할 수 있도록 된 새로운 구조의 플랜지관용 가스켓을 제공하는 것이다.The present invention is to solve the above problems, the object of the present invention is to be deformed by the pressure inside the flange tube 5, it is possible to prevent the fluid flowing along the flange tube 5 to flow out to the outside It is to provide a flange gasket of a new structure.

본 발명에 따르면, 중간부에 통공(4)이 형성된 링형상의 디스크로 구성되며, 상호 연결되는 플랜지관(5)의 사이에 설치되어, 플랜지관(5)을 상호 기밀하게 연결할 수 있도록 된 플랜지관용 가스켓에 있어서, 상기 가스켓(2)의 내부에는 링형상의 디스크로 구성된 금속재의 코어(14)가 매입설치되어, 압력에 의한 변형을 방지함과 동시에, 이 가스켓(2)의 표면에는 환형의 돌출턱(16)이 가스켓(2)과 대략 동심을 이루도록 돌출성형되어, 돌출턱(16)이 플랜지관(5)의 단부면에 가압밀착되어 플랜지관(5) 내부의 유체가 외부로 유출되는 것을 방지할 수 있도록 된 것을 특징으로 하는 플랜지관용 가스켓이 제공된다.According to the present invention, a flange is formed of a ring-shaped disk formed with a through hole 4 in the middle portion, and is installed between flange pipes 5 to be interconnected, so that the flange pipes 5 can be mutually hermetically connected to each other. In the conventional gasket, a core 14 made of a metal material composed of a ring-shaped disk is embedded in the gasket 2 to prevent deformation due to pressure and at the same time the surface of the gasket 2 has an annular shape. The protruding jaw 16 is protruded to be substantially concentric with the gasket 2, so that the protruding jaw 16 is pressed against the end face of the flange tube 5 so that the fluid inside the flange tube 5 flows outward. There is provided a gasket for a flange pipe, characterized in that it can be prevented.

이하, 본 발명의 바람직한 실시예를 첨부한 도면에 의거하여 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

도 2 및 도 3은 본 발명에 따른 플랜지관용 가스켓을 도시한 것으로, 중앙부에 통공(4)이 형성된 링형상의 디스크로 구성되며, 상호 연결되는 플랜지관(5)의 사이에 설치되어, 플랜지관(5)을 상호 기밀하게 연결할 수 있도록 된 것은 종래의 플랜지용 가스켓과 동일하다. 이때, 이 가스켓(2)에는 상기 플랜지관(5)을 상호 연결하는 볼트(6)가 관통할 수 있도록 그 둘레를 따라 다수개의 볼트공(12)이 형성된다.2 and 3 illustrate a gasket for a flange tube according to the present invention, which is composed of a ring-shaped disk having a through hole 4 formed in a central portion thereof, and is installed between the flange tubes 5 interconnected to each other. It is the same as that of the conventional flange gasket that it became possible to connect (5) mutually hermetically. In this case, a plurality of bolt holes 12 are formed in the gasket 2 along the circumference thereof so that the bolts 6 connecting the flange pipes 5 can pass therethrough.

그리고, 상기 가스켓(2)의 내부에는 가스켓(2)의 변형을 방지할 수 있도록 된 금속재의 코어(14)가 매입설치된다. 이 코어(14)는 가스켓(2)과 동일하게 링형상의 디스크로 구성되며, 그 둘레를 따라 다수개의 볼트공(13)이 형성된 것으로, 이 코어(14)에 고무재질을 인서트사출하므로써, 코어(14)가 매입된 가스켓(2)을 생산할 수 있다. 이때, 상기 코어(14)는 압축강도가 높고 연성이 있는 철이나 알루미늄 등으로 구성하는 것이 바람직하다. 또한, 이 가스켓(2)의 상하면 둘레부에는 상기 플랜지관(5)의 단부면에 가압밀착되는 여러겹의 돌출턱(16)이 형성된다. 이 돌출턱(16)은 상기 가스켓(2)과 상호 동심을 이루도록 가스켓(2)의 둘레를 따라 환형으로 돌출형성된다.In addition, a core 14 made of a metal material which is capable of preventing deformation of the gasket 2 is embedded in the gasket 2. The core 14 is composed of a ring-shaped disk similarly to the gasket 2, and a plurality of bolt holes 13 are formed along the circumference thereof, and the core 14 is inserted into the core 14 by inserting a rubber material. It is possible to produce a gasket 2 in which 14 is embedded. At this time, the core 14 is preferably made of iron or aluminum having high compressive strength and ductility. In addition, on the upper and lower circumferential portions of the gasket 2, a plurality of protruding jaws 16 press-contacted to the end face of the flange tube 5 is formed. The protruding jaw 16 protrudes in an annular shape along the circumference of the gasket 2 so as to be concentric with the gasket 2.

따라서, 이와같이 구성된 가스켓(2)을 플랜지관(5)의 연결부위에 설치하고, 볼트(6)를 이용하여 상기 플랜지관(5)을 조이면, 플랜지관(5)의 단부가 가스켓(2)의 전후면을 가압하여, 가스켓(2)의 전후면에 형성된 돌출턱(16)이 가압, 변형되면서 플랜지관(5)의 단부에 밀착되어, 플랜지관(5)을 상호 기밀하게 연결한다.Therefore, when the gasket 2 thus constructed is installed at the connection portion of the flange tube 5 and the flange tube 5 is tightened using the bolt 6, the end of the flange tube 5 is connected to the gasket 2. The front and rear surfaces are pressurized, and the protruding jaws 16 formed on the front and rear surfaces of the gasket 2 are pressed and deformed to be in close contact with the ends of the flange tubes 5, thereby connecting the flange tubes 5 to each other in an airtight manner.

이와같이 구성된 가스켓(2)은 그 내부에 금속재의 코어(14)가 매입설치되므로, 그 양측면을 가압하는 플랜지관(5)의 압력에 의해 변형되어, 플랜지관(5)의 연결부 외부로 밀려나가는 것을 방지할 수 있다. 따라서, 플랜지관(5)의 단부와 가스켓(2) 사이에 간격이 발생되어, 플랜지관(5)을 따라 흐르는 유체가 외부로 유출되는 것을 방지할 수 있다. 또한, 상기 돌출턱(16)이 압력에 의해 변형되면서, 플랜지관(5)의 단부에 밀착가압되어, 유체가 외부로 유출되는 것을 방지하는 격벽의 역할을 하므로, 플랜지관(5) 내부를 흐르는 유체가 플랜지관(5)의 단부와 가스켓(2) 사이의 틈을 통해 외부로 유출되는 것을 방지할 수 있는 장점이 있다.Since the gasket 2 constructed as described above is embedded with a metal core 14 embedded therein, the gasket 2 is deformed by the pressure of the flange tube 5 which presses both sides thereof, and is pushed out of the connecting portion of the flange tube 5. You can prevent it. Therefore, a gap is generated between the end of the flange pipe 5 and the gasket 2, so that the fluid flowing along the flange pipe 5 can be prevented from flowing out. In addition, the projection jaw (16) is deformed by the pressure, it is pressed close to the end of the flange pipe 5, and serves as a partition wall to prevent the fluid outflow, flows inside the flange pipe (5) There is an advantage that the fluid can be prevented from leaking out through the gap between the end of the flange pipe (5) and the gasket (2).

이상에서와 같이 본 발명에 의하면, 가스켓(2) 내부에 금속재의 코어(14)를 매입설치하고, 그 표면에 여러겹의 돌출턱(16)을 형성하므로써, 플랜지관(5) 내부의 압력에 의해 변형되어, 플랜지관(5)을 따라 흐르는 유체가 외부로 유출되는 것을 방지할 수 있도록 된 새로운 구조의 플랜지관용 가스켓을 제공할 수 있다.As described above, according to the present invention, the core 14 made of metal is embedded in the gasket 2, and a plurality of protruding jaws 16 are formed on the surface thereof, so that the pressure inside the flange pipe 5 is reduced. It is possible to provide a gasket for a flange tube of a new structure which is deformed by this, to prevent the fluid flowing along the flange tube 5 from leaking out.
