Abstract

PURPOSE: A coupling(VCR fitting) for pipe connection is provided to stably perform the combination of a P type fitting with an N type fitting in the semiconductor assembly line. CONSTITUTION: A VCR fitting(10) is constituted of a P type fitting(30) and an N type fitting(20). One end of the P type fitting is connected to a pipe(60), and a male thread(32) is formed in the other end. One end of the N type fitting is connected to another pipe(50), and a female thread(22) is formed in the other. A gasket(40) is interposed between the P type fitting and the N type fitting. The combination of the VCR fitting is accomplished by the thread connection of the P type fitting with the N type fitting via a lobster adjustable wrench or a spanner. Combination degree of the P type fitting and the N type fitting is kept uniform by the scales(26,36) formed on the outer faces of the P type fitting and the N type fitting. Therefore, fluid leakage or separation of the P type fitting from the N type fitting due to abnormal combination of the P type fitting and the N type fitting is avoided.

배관 연결용 커플링{COUPLING FOR PIPE CONNECTION}Coupling for pipe connection {COUPLING FOR PIPE CONNECTION}

본 발명은 배관용 커플링에 관한 것으로, 좀 더 구체적으로는 반도체 제조 라인에서 주로 사용되는 VCR 피팅(fitting)과 같은 배관용 커플링에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to piping couplings and, more particularly, to piping couplings such as VCR fittings mainly used in semiconductor manufacturing lines.

반도체 제조 라인의 배관에는 다양한 형태의 커플링(coupling)들이 사용된다. 도 1에서 보인 커플링은 VCR 피팅(100)의 일례를 보여주는 도면이다.Various types of couplings are used for piping of semiconductor manufacturing lines. The coupling shown in FIG. 1 is a diagram illustrating an example of a VCR fitting 100.

도 1을 참조하면, 일반적으로 VCR 피팅(100)은 P형 피팅(130)과 N형 피팅(120)으로 이루어진다. P형 피팅(130)은 일단에 배관(160)이 연결되어 있고, 타단에는 수나사가 형성되어 있다. N형 피팅(120)은 일단에 배관(150)이 연결되어 있고, 타단에는 암나사가 형성되어 있다. P형 피팅(130)과 N형 피팅(120) 사이에는 가스켓(gasket)(140)이 삽입된다. 이와 같은 VCR 피팅(100)의 결합은 P형 피팅(130)과 N형 피팅(120) 사이에 가스켓(140)을 넣어 P형 피팅(130)과 N형 피팅(120)을 나사결합시키고, 몽키 렌치(lobster adustable wrench) 또는 스패너(spanner) 등의 공구를 사용하여 이루어진다.Referring to FIG. 1, a VCR fitting 100 generally includes a P-type fitting 130 and an N-type fitting 120. The P-type fitting 130 has a pipe 160 connected to one end thereof and a male screw formed at the other end thereof. The N-type fitting 120 has a pipe 150 connected to one end thereof and a female thread formed at the other end thereof. A gasket 140 is inserted between the P-type fitting 130 and the N-type fitting 120. The coupling of the VCR fitting 100 is to insert the gasket 140 between the P-type fitting 130 and the N-type fitting 120 to screw the P-type fitting 130 and the N-type fitting 120, monkey This is done using tools such as a wrench adustable wrench or spanner.

그러나, 이와 같은 VCR 피팅(100)의 결합은 작업자의 감각에 의해서 이루어 지므로, 각 작업자마다 서로 다른 형태로 P형 피팅(130)과 N형 피팅(120)을 조이게 된다. 따라서, P형 피팅(130)과 N형 피팅(120)의 결합이 정상적으로 이루어지지 않아서 배관을 흐르는 유체의 누수가 발생하거나, P형 피팅(130)과 N형 피팅(120)의 분리가 되지 않는 경우가 발생하게 된다.However, since the coupling of the VCR fitting 100 is made by the operator's senses, the P-type fitting 130 and the N-type fitting 120 are tightened in different forms for each operator. Therefore, the coupling between the P-type fitting 130 and the N-type fitting 120 does not occur normally, so that leakage of fluid flowing through the pipe may not occur, or the P-type fitting 130 and the N-type fitting 120 may not be separated. There is a case.

본 발명은 이와 같은 종래 문제점을 해결하기 위한 것으로, 그 목적은 배관용 커플링을 결합시킬 때 작업자가 용이하게 결합시킬 수 있도록 하고, 일정한 결합력을 갖도록 커플링을 결합시킬 수 있는 새로운 형태의 배관용 커플링을 제공하는데 있다. 특히, 본 발명은 P형 피팅과 N형 피팅의 결합을 안정적으로 수행할 수 있는 새로운 형태의 VCR 피팅을 제공하는데 있다.The present invention is to solve such a conventional problem, the object is to enable the operator to easily combine when coupling the coupling for the pipe, a new type of pipe that can be coupled to the coupling to have a constant coupling force To provide a coupling. In particular, the present invention provides a new type of VCR fitting that can stably perform a combination of a P-type fitting and an N-type fitting.

상술한 바와 같은 목적을 달성하기 위한 본 발명에 따르면, 본 발명은 제 1 커플링과 제 2 커플링을 갖고, 두 배관을 연결하는 배관용 커플링을 제공한다. 이 배관용 커플링에서 제 1 커플링은 제 1 외부면을 갖는다. 제 2 커플링은 제 1 커플링에 결합되고, 제 1 외부면과 대응되는 제 2 외부면을 갖는다. 제 1 커플링의제 1 외부면과 제 2 커플링의 제 2 외부면에는 서로 대응되는 눈금이 형성된다. 따라서, 제 1 커플링과 제 2 커플링을 결합시킬 때 작업자는 제 1 외부면과 제 2 외부면에 형성된 눈금을 확인하여 제 1 커플링과 제 2 커플링의 결합량을 조절할 수 있다.According to the present invention for achieving the object as described above, the present invention provides a pipe coupling having a first coupling and a second coupling, connecting the two pipes. In this piping coupling the first coupling has a first outer surface. The second coupling is coupled to the first coupling and has a second outer surface corresponding to the first outer surface. Scales corresponding to each other are formed on the first outer surface of the first coupling and the second outer surface of the second coupling. Therefore, when coupling the first coupling and the second coupling, the operator can check the scales formed on the first outer surface and the second outer surface to adjust the coupling amount of the first coupling and the second coupling.

이와 같은 본 발명의 배관용 커플링에서 상기 제 1 커플링은 수나사가 형성된 P형 피팅이고, 상기 제 2 커플링은 상기 P형 피팅의 수나사가 결합되는 암나사가 형성된 N형 피팅일 수 있다.In the pipe coupling of the present invention, the first coupling may be a P-type fitting with a male thread, and the second coupling may be an N-type fitting with a female thread to which the male thread of the P-type fitting is coupled.

이하, 도 2를 참조하면서 본 발명의 바람직한 실시예에 따른 배관용 커플링을 상세히 설명한다.Hereinafter, the piping coupling according to a preferred embodiment of the present invention with reference to Figure 2 will be described in detail.

도 2를 참조하면, 본 발명의 바람직한 실시예에 따른 VCR 피팅(10)은 P형 피팅(30)과 N형 피팅(20)으로 이루어진다. P형 피팅(30)은 일단에 배관(60)이 연결되어 있고, 타단에는 수나사(32)가 형성되어 있다. N형 피팅(20)은 일단에 배관(50)이 연결되어 있고, 타단에는 암나사(22)가 형성되어 있다. P형 피팅(30)과 N형 피팅(20) 사이에는 가스켓(gasket)(40)이 삽입된다. 이와 같은 VCR 피팅(10)의 결합은 P형 피팅(30)과 N형 피팅(20) 사이에 가스켓(40)을 넣어 P형 피팅(30)과 N형 피팅(20)을 나사결합시키고, 몽키 렌치(lobster adustable wrench) 또는 스패너(spanner) 등의 공구를 사용하여 이루어진다.2, the VCR fitting 10 according to the preferred embodiment of the present invention consists of a P-type fitting 30 and the N-type fitting 20. The P-type fitting 30 has a pipe 60 connected to one end thereof and a male screw 32 formed at the other end thereof. The N-type fitting 20 has a pipe 50 connected to one end and a female screw 22 formed on the other end thereof. A gasket 40 is inserted between the P-type fitting 30 and the N-type fitting 20. The coupling of the VCR fitting 10, the gasket 40 is inserted between the P-type fitting 30 and the N-type fitting 20 to screw the P-type fitting 30 and the N-type fitting 20, and the monkey This is done using tools such as a wrench adustable wrench or spanner.

한편, P형 피팅(30)의 외부면(24)에는 눈금(26)이 형성되어 있으며, N형 피팅(20)의 외부면(34)에는 눈금(34)이 형성되어 있다. 이와 같이 P형 피팅(30)과 N형 피팅(20)에 서로 대응되도록 형성된 눈금(26,36)을 사용하므로써 작업자는 P형피팅(30)과 N형 피팅(20)의 결합량을 항상 일정한 수준으로 유지할 수 있는 것이다.On the other hand, a scale 26 is formed on the outer surface 24 of the P-type fitting 30, and a scale 34 is formed on the outer surface 34 of the N-type fitting 20. By using the graduations 26 and 36 formed to correspond to each other in the P-type fitting 30 and the N-type fitting 20 as described above, the operator always maintains a constant coupling amount between the P-type fitting 30 and the N-type fitting 20. It can be maintained at the level.

따라서, 상기 VCR 피팅(10)에서 P형 피팅(30)과 N형 피팅(20)의 결합량은 항상 일정하게 관리할 수 있으므로, P형 피팅(30)과 N형 피팅(20)의 결합이 정상적으로 이루어지지 않아서 배관을 흐르는 유체의 누수가 발생하거나, P형 피팅(30)과 N형 피팅(20)의 분리가 되지 않는 경우가 발생하게 되는 것을 방지할 수 있다.Therefore, since the coupling amount of the P-type fitting 30 and the N-type fitting 20 in the VCR fitting 10 can always be constantly managed, the combination of the P-type fitting 30 and the N-type fitting 20 is It may be prevented that the leakage of the fluid flowing through the pipe does not occur normally, or the case where the P-type fitting 30 and the N-type fitting 20 are not separated.

이와 같은 본 발명에 의하면, 배관용 커플링을 결합시킬 때 결합력을 항상 일정한 수준으로 작업자가 용이하게 결합시킬 수 있다. 특히, P형 피팅과 N형 피팅을 안정된 결합량으로 고정할 수 있으므로, 작업자의 잘못된 결합으로 인하여 유체가 누출되는 문제점을 극복할 수 있다.According to the present invention as described above, the operator can be easily coupled to a certain level of coupling force at all times when coupling the pipe coupling. In particular, since the P-type fittings and the N-type fittings can be fixed at a stable coupling amount, it is possible to overcome the problem of fluid leakage due to incorrect coupling of the operator.
