Abstract

The present invention relates to a poly tetra fluoro ethylene (P.T.F.E) jacket gasket with a detachable outer ring which can be securely fixated to a gap between flanges, and can replace the jacket gasket without disassembling the flanges.

Description

착탈식 외륜을 가진 P.T.F.E 자켓가스켓 { P.T.F.E JACKET GASKET WITH DETACHABLE OUTER RING } P.T.F.E jacket gasket with detachable outer ring {P.T.F.E JACKET GASKET WITH DETACHABLE OUTER RING}

본 발명은 플랜지 사이에 삽입되는 P.T.F.E 자켓가스켓(이하 '자켓카스켓'이라 한다)에 관한 것이다.The present invention relates to a PTFE jacketed gasket (hereinafter referred to as a jacket casket) inserted between flanges.

본 발명에서 P.T.F.E의 범위는 P.T.F.E(POLY TETRA FLUORO ETHYLENE), NEW P.T.F.E(NEW POLY TETRA FLUORO ETHYLENE), PFA(PER FLUORO ALKOXY) 성분의 불소수지를 포함한다.In the present invention, the scope of P.T.F.E includes fluororesin of P.T.F.E (POLY TETRA FLUORO ETHYLENE), NEW P.T.F.E. (NEW POLY TETRA FLUORO ETHYLENE) and PFA (PER FLUORO ALKOXY).

관과 관, 관과 다른 기계 부분을 연결할 때 쓰이는 부품을 플랜지(Flange)라고 한다. 플랜지는 금속 면을 맞대고 결합되는데 플랜지 사이에 가스켓을 끼워서 결합하면 내부로 흐르는 유체가 결합 부위의 틈으로 새어 나오는 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 bonded to the metal surface. When the gasket is inserted between the flanges, the fluid that flows into the flange can be lowered to the gap of the joint portion, which is called a sealing effect.

가스켓은 플랜지 사이에 끼워져 강한 압력을 받고 강산·강알카리성 유체와 접촉하게 되는데, 복원력이 우수한 비금속으로 된 가스켓에 P.T.F.E 자켓을 씌워서 외부 힘에 의한 변형을 막고 외부물질에 의한 부식을 방지한 것을 P.T.F.E 자켓가스켓이라고 한다. 기존의 자켓가스켓은 FLAT RING TYPE이나 FULL FACE TYPE으로 된 일체형의 자켓가스켓으로 이루어져 플랜지에 장착된 자켓가스켓을 교체시 FULL FACE TYPE일 경우 폐기해야 하지만 본 발명은 내부의 FLAT RING TYPE의 자켓가스켓을 교체하여 외부에 결합된 가스켓은 재사용이 가능하다.The gasket is sandwiched between the flanges and is subjected to strong pressure and comes into contact with strong acid and strong alkaline fluid. PTFE jacket is covered with a nonmetallic gasket with good resilience to prevent deformation by external force and prevent corrosion by external substances. PTFE jacket It is called a gasket. The existing jacket gasket is composed of integral jacket gasket made of FLAT RING TYPE or FULL FACE TYPE. When replacing the jacket gasket mounted on the flange, it is necessary to dispose of the gasket when it is a FULL FACE TYPE. So that the gasket coupled to the outside is reusable.

본 발명이 이루고자 하는 기술적 과제는 플랜지 사이에 끼워져 있는 자켓가스켓의 씰링부분을 교체할 수 있는 착탈식 외륜을 가진 자켓 가스켓을 제공하는 것이다.SUMMARY OF THE INVENTION It is an object of the present invention to provide a jacket gasket having a detachable outer ring capable of replacing a sealing portion of a jacket gasket sandwiched between flanges.

상기 기술적 과제를 달성하기 위하여, 본 발명의 일 형태에 따른 착탈식 외륜을 가진 자켓가스켓은 도너츠 형태의 자켓가스켓; 및 자켓가스켓의 바깥 부분과 탈부착이 가능한 외륜;을 포함한다.According to an aspect of the present invention, there is provided a jacket gasket having a detachable outer ring according to an aspect of the present invention includes: a donut-shaped jacket gasket; And an outer ring capable of being attached to and detached from the outer portion of the jacket gasket.

상기 자켓가스켓은 플랜지 사이에 끼워져서 유체가 결합 부위의 틈으로 새어나가는 것을 방지하는 가스켓의 외부에 P.T.F.E 자켓을 씌운 것이다.The jacket gasket is a P.T.F.E jacket on the outside of the gasket which is sandwiched between the flanges to prevent the fluid from escaping into the gap of the joint.

상기 자켓가스켓의 바깥 부분은 홈에 끼워질 수 있도록 바깥으로 갈 수로 두께가 얇아진다.The outer portion of the jacket gasket is thinned to the outside so as to be fitted in the groove.

상기 외륜은 상기 자켓가스켓의 바깥 부분과 탈부착이 가능하도록 안쪽으로 홈이 파져있다.The outer ring is grooved inwardly so as to be detachable from the outer portion of the jacket gasket.

상기 외륜에는 플랜지에 고정되기 위한 구멍이 일정 간격으로 뚫려 있다.The outer ring is provided with holes for fixing to the flange at regular intervals.

본 발명의 실시례에 따르면 관을 통해 흐르는 유체의 종류가 변경되거나 사용기간이 오래되어 새로운 자켓가스켓으로 교체할 필요성이 있을 경우, 내부의 자켓가스켓은 새로운 자케가스켓으로 손쉽게 교체하면서도 플랜지와의 고정을 위한 외부의 외륜은 재사용 함으로써 원자재 절감 등 비용을 줄일 수 있다.According to the embodiment of the present invention, when the type of fluid flowing through the pipe is changed or the use period is long and it is necessary to replace with a new jacket gasket, the inner jacket gasket can be easily replaced with a new jacket gasket, The outer paddle for reuse can reduce the cost of raw materials and the like.

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 도3에서 도시한 바와 같이 도너츠 형태의 자켓가스켓(100)과 자켓가스켓(100)의 바깥 부분과 결합되는 외륜(200);을 포함한다.The present invention includes a donut-shaped jacket gasket 100 and an outer ring 200 coupled with an outer portion of the jacket gasket 100 as shown in FIG.

자켓가스켓(100)은 도1에서 도시한 바와 같이 바깥 부분이 홈에 끼워질 수 있도록 바깥부분의 두께가 얇다.As shown in FIG. 1, the outer portion of the jacket gasket 100 is thin so that the outer portion can be inserted into the groove.

외륜(200)은 도2에서 도시한 바와 같이 일정 간격으로 4개의 구멍이 뚫려 있고 이를 통해 플랜지에 고정되는데, 본 발명의 보호범위가 4개라는 개수에 한정되는 것으로 이해되어서는 안된다.As shown in FIG. 2, the outer ring 200 has four holes at regular intervals and is fixed to the flange through the holes. It should not be understood that the scope of protection of the present invention is limited to four.
