Description

파이프 밀폐용 마개Pipe closure stopper
본 발명은 파이프 밀폐용 마개에 관한 것으로, 더욱 구체적으로는 파이프의 끝단에 간편하고 신속하게 마개 결합이 되면서 마개가 내벽에 긴밀하게 밀착 지지되어 강한 유체압력이나 진동에도 밀림이나 이탈이 되지 않을 뿐만 아니라 부품수를 줄여 제조단가를 낮출 수 있는 파이프 밀폐용 마개에 관한 것이다.The present invention relates to a pipe closure stopper, and more specifically, the stopper is coupled to the end of the pipe easily and quickly, and the stopper is tightly supported on the inner wall so as not to be pushed or separated from strong fluid pressure or vibration. It relates to a pipe closure stopper that can reduce the manufacturing cost by reducing the number of parts.
일반적으로 파이프의 끝단에 마개를 설치하는 경우는, 파이프의 내부에 이물질 등이 유입되는 것을 차단하도록 하는 것뿐만 아니라 모든 동력 장치나 액체, 기체와 같은 유체의 수송, 이동에 필요한 배관을 설치하면서 파이프의 일부분에서는 유체의 흐름을 차단하기 위해 파이프의 끝단부에 마개를 결합시켜 밀폐시키게 된다.In general, when installing a stopper at the end of a pipe, not only to prevent foreign matters from entering the inside of the pipe, but also to install and install pipes for transporting and moving all power devices, fluids such as liquids and gases, etc. In part of the seal, a stopper is coupled to the end of the pipe to block the flow of fluid.
종래의 파이프의 끝단에 마개를 설치하는 수단으로는 쐐기 형태의 마개를 헤머 등의 도구로 타격하여 억지로 끼워넣어 고정하는 수단, 파이프 마개와 파이프를 용접하여 고정하는 마개의 용접수단, 파이프 마개의 일부에 수나사부를 형성시키고 파이프의 끝부분 내측에 암나사부를 형성시켜 나사체결하여 고정하는 마개의 나사결합수단 등을 사용하고 있다.As a means for installing a stopper at the end of a conventional pipe, a means for forcing a wedge-shaped stopper with a tool such as a hammer and forcing it to be fixed, a welding means for welding a pipe stopper and a pipe, and a part of a pipe stopper A screw thread means for forming a male thread in the male thread, a female thread in the inner end of the pipe, and screwing and fixing the screw is used.
상기에서 쐐기 형태의 마개를 강제 끼움으로 고정하는 수단은, 파이프의 끝단부에 쐐기가 밀려 들어가면서 고정되고 파이프의 내벽과 쐐기의 측벽면 사이의 밀착 지지력이 떨어져서 강한 유체압력에 외측으로 밀려나거나 이탈될 우려가 많기 때문에 유체압력 차단을 위한 마개로는 적합하지 않고 주로 파이프의 내부에 이물질이 차단되는 것을 방지하는 용도 등에 사용이 된다.The means for fixing the wedge-shaped stopper by force fitting is fixed as the wedge is pushed into the end of the pipe, and the close supporting force between the inner wall of the pipe and the side wall surface of the wedge may be pushed out or separated by strong fluid pressure. Since there are many concerns, it is not suitable as a stopper for blocking fluid pressure and is mainly used for preventing foreign matters from being blocked inside the pipe.
그리고 파이프 내부에 강한 유체압력이 가해지는 파이프의 끝단을 차단하기 위해 사용되는 마개로는, 상기 마개의 용접수단 또는 마개의 나사결합수단이 사용되고 있다.As the stopper used to block the end of the pipe to which a strong fluid pressure is applied inside the pipe, the welding means of the stopper or the screwing means of the stopper is used.
또한, 상기 마개의 나사결합수단은, 파이프 마개의 일부에 수나사부를 형성시키고 파이프의 끝부분 내측에 암나사부를 형성시켜 나사체결하여 고정하는 수단을 사용하고 있는바 이는 파이프와 마개에 나사탭을 형성하는 공정을 필요로 할 뿐만 아니라 현장에서 파이프를 절단한 다음 곧바로 나사탭이 없는 파이프에는 마개를 결합할 수 없는 등 작업성이 크게 떨어지게 되고, 나사결합만으로는 완전 밀폐가 되지 않으므로 패킹을 사용해야 되고, 제조단가도 많이 들게 되었으며, 특히 자동차 배관과 같이 진동이 발생하는 곳에 파이프 마개를 나사결합하여 사용하는 경우에는 자동차로부터 전달되는 진동에 의해 파이프 마개의 나사결합부분이 풀리거나 유체압력에 의해 밀려 빠져나가는 문제점이 있다.In addition, the screwing means of the stopper, a male threaded portion is formed in a portion of the pipe stopper and a female threaded portion is formed inside the end of the pipe by means of screw fastening, which is used to form a screw tab on the pipe and the stopper. Not only does it require a process, but after cutting the pipe in the field, workability is greatly reduced, such as a plug not being attached to a pipe without a thread tap, and a packing must be used since it is not completely sealed by screwing alone. In particular, when the pipe plug is screwed to a place where vibration occurs, such as an automobile pipe, the screw coupling part of the pipe plug is loosened or pushed out by the fluid pressure. have.
상기와 같은 마개의 나사결합수단을 문제점을 감안하여 선행기술로서 실용신안등록 제20-0461502호의 '파이프 마개'에서는 제1 몸체부와, 상기 제1 몸체부의 일측으로 연장되고 내면에 암나사부가 형성되는 제2 몸체부를 구비하는 너트형 본체; 상기 너트형 본체의 암나사부에 나사 결합되도록 외면에 수나사부가 형성되는 샤프트와, 상기 샤프트의 단부에서 상기 샤프트의 직경보다 크게 형성되는 헤드를 구비하는 볼트부재; 상기 너트형 본체와 상기 볼트부재 사이에 배치되되 상기 샤프트가 통과되는 절개형 통공 및 상기 절개형 통공 외곽으로 연장 형성되는 링부를 포함하며, 상기 링부는 경사배치되며, 내측면보다 외측면이 상대적으로 길게 형성되어 상기 헤드의 가압 시 파이프의 내벽에 탄성적으로 기밀 지지되는 스냅링 와셔; 상기 너트형 본체와 상기 스냅링 와셔 사이에 배치되어 상기 볼트부재의 가압력을 상기 파이프 내측으로 전달하면서, 스냅링 와셔의 탄성을 유지시키는 가압부재; 및 상기 너트형 본체와 상기 가압부재 사이에는 개재 되는 오링(O-Ring)을 포함하는 구성으로 파이프 마개의 볼트 풀림 또는 파이프 마개의 밀림이나 이탈 현상을 예방할 수 있도록 하였다.In view of the problems of the screw coupling means of the plug as described above in the 'pipe stopper' of the Utility Model Registration No. 20-0461502 as a prior art extends to the first body portion, one side of the first body portion and the internal thread is formed on the inner surface A nut-shaped body having a second body portion; A bolt member having a shaft having a male screw portion formed on an outer surface thereof so as to be screwed to a female screw portion of the nut-shaped body, and a head formed larger than a diameter of the shaft at an end of the shaft; It is disposed between the nut-like body and the bolt member, and includes a ring portion extending to the outside of the cut through hole and the cut through hole through which the shaft passes, the ring portion is inclined, the outer surface is relatively than the inner surface A snap ring washer formed to be long and elastically hermetically supported on an inner wall of the pipe when the head is pressed; A pressing member disposed between the nut-shaped body and the snap ring washer to transmit the pressing force of the bolt member to the inside of the pipe and to maintain elasticity of the snap ring washer; And an O-ring interposed between the nut-shaped body and the pressing member to prevent bolt loosening of the pipe stopper or push or detachment of the pipe stopper.
그러나 상기 문헌에 개시된 종래기술의 경우에도, 구조적인 한계로 인해 많은 부품사용으로 전체적인 단가가 높아질 뿐만 아니라 파이프 내벽에 스냅링 와셔만으로 기밀 지지되게 한 것이어서 강한 유체압력에 스냅링 와셔가 변형되거나 파손되어 강한 지탱력을 발휘할 수 없는 문제점이 있다.However, even in the prior art disclosed in the above document, due to structural limitations, the overall cost is increased due to the use of many parts, and the inner wall of the pipe is hermetically supported only by the snap ring washer, so that the snap ring washer is deformed or broken under strong fluid pressure, and thus it is strongly supported. There is a problem that can not exert power.
본 발명은 이러한 문제점을 해결하기 위하여 안출한 것으로, 단일 몸체에 파이프의 끝단에 끼워지는 밀착지지부와, 상기 밀착지지부의 상부 중앙에 돌출된 가압돌부와, 상기 가압돌부가 분리 타격될 수 있도록 하는 절개부로 된 마개가 구비되어 있는 간단한 구조의 파이프 밀폐용 마개를 제공함에 있다.The present invention has been made in order to solve the above problems, a close support that is fitted to the end of the pipe in a single body, the pressing protrusion protruding in the upper center of the close support portion, the incision so that the pressing protrusion can be separated blow It is to provide a pipe closure stopper of a simple structure provided with a negative stopper.

또한, 본 발명의 마개(100)가 결합되는 파이프(200)는 강관 등으로 된 금속제뿐만 아니라 합성수지관에도 적용될 수 있다.In addition, the pipe 200 to which the stopper 100 of the present invention is coupled may be applied to a synthetic resin pipe as well as a metal made of a steel pipe or the like.
이와 같이 된 본 발명은 도 2 및 도 3과 같이 단일 몸체에 파이프(200)의 끝단에 끼워지는 밀착지지부(110)와, 상기 밀착지지부(110)의 상부 중앙에 돌출된 가압돌부(120)와, 상기 가압돌부(120)가 분리 타격될 수 있도록 하는 절개부(130)가 각각 구비되어 있는 마개(100)를 이용하여 파이프(200)의 끝단에 간편하고 신속하게 결합하는 수단으로 강한 유체압력이나 진동에도 밀림이나 이탈이 되지 않고 항구적으로 밀폐시킬 수 있게 된다.As described above, the present invention has a close support 110 that is fitted to the end of the pipe 200 in a single body, as shown in Figure 2 and 3, and the pressing protrusion 120 protruding in the upper center of the close support 110 By means of the stopper 100, which is provided with each of the cutouts 130 so that the pressing protrusions 120 can be separated and blown, the fluid can be easily and quickly coupled to the end of the pipe 200. It can be sealed permanently without being pushed or separated by vibration.
이는 도 4와 같이 파이프(200)의 끝단에 별도의 나사성형 등을 하지 않고 밀착지지부(110)를 곧바로 끼워 플랜지(116)로 끼움 상태를 유지시킨 다음 해머 등의 타격부재를 이용하여 가압돌부(120)의 상면을 타격하게 되면 타격압력에 의해 절개부(130)가 절개됨과 동시에 가압돌부(120)가 절개부(130)에서 분리되면서 가압돌부(120)의 하부 경사면(124)이 밀착지지부(110)의 중공부(112)로 진입이 이루어진다.This is to insert the close support 110 directly to the end of the pipe (200) as shown in Figure 4 without the additional screw molding and maintain the fitted state by the flange 116 and then using a pressing member such as a hammer protrusion ( When hitting the upper surface of the 120, the incision 130 is cut by the impact pressure and at the same time the pressing protrusion 120 is separated from the incision 130, the lower inclined surface 124 of the pressing protrusion 120 is in close contact with the support ( Entry into the hollow portion 112 of the 110 is made.
상기와 같이 가압돌부(120)이 하부 경사면(124)에 의해 밀착지지부(110)의 계속적인 진입이 이루어지면, 도 5와 같이 상기 밀착지지부(110)의 내경보다 큰 직경의 외경으로 된 가압돌부(120)의 측부 압지면(122)은 밀착지지부(110)의 내벽에 가압 밀착되면서 진입이 됨과 동시에 밀착지지부(110)의 측부 밀착면(114)은 파이프(200)의 내벽에 가압 밀착이 된다.As described above, when the pressing protrusion 120 continuously enters the close support 110 by the lower inclined surface 124, the pressing protrusion 120 has an outer diameter of a diameter larger than the inner diameter of the close support 110. The side pressing surface 122 of 120 enters while being pressed in close contact with the inner wall of the close supporting part 110, and at the same time, the side closely contacting surface 114 of the close supporting part 110 is pressed in close contact with the inner wall of the pipe 200. .
즉, 가압돌부(120)의 측부 압지면(122)은 밀착지지부(110)의 내벽에 가압 밀착되는 측방압력으로 밀착지지부(110)의 측부 밀착면(114)은 파이프(200)의 내벽에 가압 밀착이 되어 긴밀한 밀착상태를 유지하게 되는 것으로서, 이는 가압돌부(120)와 밀착지지부(110)가 측방압력으로 조직이 치밀해지면서 강한 밀착력을 발휘하게 된다.That is, the side pressing surface 122 of the pressing protrusion 120 is pressurized to the inner wall of the tight support 110, and the side contact surface 114 of the tight support 110 is pressurized to the inner wall of the pipe 200. As it is in close contact to maintain a close contact state, which is a pressure protrusion 120 and the close support 110 is a close contact with the lateral pressure, the structure exhibits a strong adhesion.
이때 파이프(200)의 경도에 따라서는 파이프(200)의 끝단에 결합되는 밀착지지부(110)와 가압돌부(120)의 측방압력에 의해 마개(100)가 결합된 파이프(200)의 끝단이 외측으로 미세하게 벌어질 정도의 측방압력으로 긴밀한 밀착상태를 유지하게 된다.At this time, depending on the hardness of the pipe 200, the end of the pipe 200 coupled with the stopper 100 by the lateral pressure of the close support 110 and the pressure protrusion 120 coupled to the end of the pipe 200 is the outside By maintaining the close contact state with the lateral pressure of the microscopic opening.
이와 같이 본 발명은 이음매가 있는 용접강관으로 내경이 거친면으로 이루어진 파이프(200)에도 내경을 매끄럽게 하는 별도의 가공과정을 거치지 않도록 않더라도 본 발명에 의한 마개(100)를 이용하여 용이하게 결합할 수 있으며, 파이프(200)의 끝단에 마개(100)를 설치하여 밀폐하고자 할 때 현장에서 파이프(200)의 끝단을 절단한 다음 절단부위에 밀착지지부(110)를 끼우고 가압돌부(120)를 타격하여 끼움 결합하는 것만으로도 항구적으로 결합되게 하는 마개 결합작업을 간편하게 할 수 있게 되어 작업생산성도 높일 수 있게 된다.As described above, the present invention can be easily combined using the stopper 100 according to the present invention even if the pipe 200 made of a rough welded inner pipe is not subjected to a separate processing process for smoothing the inner diameter. In order to seal by installing the stopper 100 at the end of the pipe 200, the end of the pipe 200 is cut at the site, and then the close support part 110 is inserted into the cut part and the pressure protrusion 120 is hit. By simply plugging together, the stopper can be easily combined with the stopper to be permanently combined, thereby increasing work productivity.
이상에서 본 발명은 상기 실시예를 참고하여 설명하였지만 본 발명의 기술사상 범위 내에서 다양한 변형실시가 가능함은 물론이다.In the above, the present invention has been described with reference to the above embodiment, but various modifications can be made within the technical scope of the present invention.
