본 발명은 각종 합성수지제 유체이송관, 즉 외주면에 돌출부와 요입부를 나선형으로 형성한 나선파형관(Corrugated pipe)이나 외주면이 평활한 일반 관체(pipe)의 연결접속부 누수방지 구조에 관한 것으로서, 연결접속되는 유체이송관과 이를 체결시키는 접속구 사이에 생기는 틈새를 확실하게 밀폐하여 완벽한 누수방지가 이루어지도록 구성한 것이다.The present invention relates to a fluid transfer pipe made of various synthetic resins, that is, a corrugated pipe in which a protrusion and a concave part are formed spirally on an outer circumferential surface, or a connection connecting part of a general pipe having a smooth outer circumferential surface. The gap between the pipe and the connection port for fastening it is sealed to ensure perfect leak prevention.
유체이송관 중에서 나선 돌출부와 요입부가 형성된 나선파형관의 경우, 이들을 접속 연결하기 위한 종래의 연결구조로는 외주면과 거의 동일한 형상 및 크기의 나선파형을 내주면에 형성시킨 원통형 나선 접합구나 소켓, 반원형 접합구 등으로 접속하여 왔으며, 이중 반원형 접속구는 비교적 그 사용이 간편할 뿐만 아니라 확실하게 체결된다는 점에서 선호하여 왔던 것이다.In the case of a spiral wave tube having a spiral protrusion and a recessed portion among the fluid transfer tubes, a conventional connection structure for connecting and connecting them is a cylindrical spiral splice, a socket, a semicircular splice, etc., in which a spiral wave having a shape and size almost the same as the outer circumferential surface is formed on the inner circumferential surface. The double semicircular connector is preferred because it is relatively easy to use and securely fastened.
그러나, 본인의 특허출원 제 95-36707호 및 제 95-36708호의 반원형 접합구를 사용한 접속구조를 지내력이 약하거나 부동침하가 생길 수 있는 장소에 매설하여 사용해 본 경험에 의하면, 체결된 접속구조 부위의 인장력이 약하여 부동침하 등의 외압에 의해 양 접속관의 이음새가 벌어져서 누수방지 기능을 지속적으로 유지할 수 없게 되는 것이다.However, according to the experience of using the semi-circular splices of the patent application Nos. 95-36707 and 95-36708, buried in a place where the bearing capacity is weak or floating may occur, Due to the weak tensile force, the joints of both connecting pipes are opened due to external pressure such as floating settlement, so that the leakage preventing function cannot be maintained continuously.
특히, 철판보강재를 매입하여 돌출부와 요입부를 나선형으로 형성한 나선파형관은 그 내압강도가 우수하여 근자에 수요가 급증하고 있으나, 일정압력 이상의 내압력이 가해지는 경우에는 상기한 바와 같은 종래의 접속수단으로서는 누수를 방지할 수 없다는 것을 당 업계는 물론, 수요자간에 너무나 잘 알려져 있어 나선파형관의 사용에 많은 문제를 제기하고 있으므로 그 사용을 확대 보급시키기 위해서는 확실하게 누수를 방지할 수 있는 접속부 누수방지 구조의 제안이 요구되는 것이었다.In particular, spiral wave pipes having a protruding portion and a recessed portion formed spirally by embedding a steel sheet reinforcing material have excellent pressure resistance and are rapidly increasing in demand. However, when a pressure higher than a certain pressure is applied, the conventional connecting means as described above. It is too well known in the industry and among consumers that it is not possible to prevent leaks. Therefore, in order to expand and spread the use of the spiral wave tube, it is necessary to provide a leak prevention structure that can reliably prevent leakage. Proposals were required.
따라서, 접속되는 양측 나선파형관의 접속단부에 해당하는 요입부에 물막이용 고무돌편이 각각 끼워지고, 돌출부에는 감합대를 돌려감은 다음 그 위에 고무시트를 넓게 덮어 씌운 후 상하 접속구를 마주보게 체결함으로써 접속부위의 수밀을 기하도록 한 것이 제안되기도 하였으나, 이것도 완벽한 수밀효과를 얻을 수는 없었던 것이다.Therefore, the rubber stone pieces for the water barrier are respectively inserted into the recesses corresponding to the connection ends of the two spiral wave pipes to be connected, and the protrusions are rotated by fitting the fitting table, and then the rubber sheet is widely covered thereon, and then the upper and lower connection ports face each other. Although it was suggested that the area be watertight, this also could not achieve a perfect watertight effect.
본 발명자는 상기한 바와 같이, 각종 유체이송관의 접합에 있어 비교적 그 체결이 간편한 반원형 접속구를 사용하는 여러 종류의 누수방지 수단을 시험하여 본 결과, 보다 완벽한 수밀효과를 얻기 위하여 다음과 같은 접속부 누수방지 구조를 제안하게 된 것이다.As described above, the present inventors have tested various types of leak prevention means using semi-circular connectors that are relatively easy to fasten when joining various fluid transfer pipes, and as a result, in order to obtain a more perfect watertight effect, the following connection leakage prevention is The structure was proposed.
즉, 합성수지 관체를 연결하는 방법에 있어서 가장 바람직한 것은 접합면을 용접하는 것이기는 하나, 합성수지 재질은 연결부위가 취약하므로 일정한 접속구로 이를 보강해야 할 필요가 있음은 주지의 사실이다.In other words, the most preferable method for connecting the synthetic resin pipe is to weld the joint surface, but the synthetic resin material is a weak connection part, it is well known that it is necessary to reinforce it with a constant connection.
따라서, 나선파형관을 연결접속하는 경우에는 그 접속단부인 요입부에 끼워지는 물막이용 고무 돌편이 일체로 연설된 물막이용 감합대를 나선파형관의 돌출부에 돌려감은 상태로 끼우고, 상기의 양 감합대 및 고무돌편 표면을 한쌍의 반원형 접속구로 눌러 체결시킬 때 접속단부 틈새를 통해 누출된 유체가 반원형 접속구의 양측 체결부 틈새로 누수되지 않도록 접속단부와 양측 체결부 틈새를 막아주는 별도의 패킹을 요입부에 끼워주는 것만으로 나선 파형관의 접속부위가 밀봉되도록 하고, 일반 관체를 접속하는 경우에는 양 관체의 접속부위 단부에 패킹 링을 각각 끼우고, 상기 패킹 링을 한쌍의 반원형 접속구로 눌러 체결시킬 때 접속단부 틈새를 통한 누출유체가 반원형 접속구의 양측 체결부 틈새로 누수되지 않도록 접속단부와 양측 체결부 틈새를 막아주는 별도의 패킹을 양 관체의 패킹 링 사이에 끼워주므로서 관체의 접속부위가 밀봉되도록 하는 것이다.Therefore, in the case of connecting and connecting the spiral wave tube, the fitting portion for the water cladding in which the rubber diaphragm inserted into the concave portion as the connection end is integrally inserted is inserted in the state of being wound around the protrusion of the spiral wave tube. And a separate packing that closes the gap between the connection end and the both ends so that the fluid leaked through the gap between the connection ends is not leaked into the gap between the both ends of the semicircular connection when pressing the surface of the rubber piece with a pair of semi-circular connectors. When connecting the common pipe, the packing ring is inserted into the end of the connecting part of both pipes, and the packing ring is pressed by a pair of semi-circular connectors. Connection end and both ends to prevent leakage fluid from leaking through the gap between the ends of the semicircular connector To ensure that a separate seal for preventing the new because sandwiched between the packing rings of the two standing tube sealing the joint portion of the pipe body.
본 발명은 상기한 바와 같이 나선파형관이나 일반 관체의 접속단부 틈새를 통해 누출되는 유체가 파형관의 경우에는 물막이용 감합대 및 고무 돌편의 표면을 반원형 접속구가 눌러 체결됨으로 해서 생기는 요입부(접속단부의 틈새가 형성된 부분)내에 들어차게 되며, 일반 관체의 경우는 접속단부의 양측 패킹 링 사이에 들어차게 되면서 상하 반원형 접속구의 체결부위 틈새를 통해 외부로 누수케 되는데, 이때 체결부 틈새를 막아주는 패킹을 상하 반원형 접속구의 체결부 내면에 절반씩 물리는 상태로 양측 접속단부에 끼워주므로서 접속부위의 누수를 방지토록 한 누수방지 구조의 제공을 목적으로 하는 것이다.As described above, in the case of the corrugated pipe, the fluid leaked through the gap between the connection end of the spiral wave tube or the general pipe is a concave part formed by pressing the semi-circular connection port on the surface of the water fitting fitting and the rubber protrusion. In the case of a general pipe, it enters between the packing rings on both sides of the connection end, and leaks to the outside through the gap between the fastening parts of the upper and lower semi-circular splices. It is an object of the present invention to provide a leakage preventing structure that prevents leakage of a connection part by being inserted into both connection ends while being half bitten on the inner surface of the coupling part of the upper and lower semi-circular connection ports.
