Description

밀폐밀착력이 향상된 관체연결용 패킹{A Packing for Pipes Connection}[0001] A Packing for Pipes Connection [0002]

본 발명은 관체와 관체의 단부를 연결관의 내부에서 서로 연결시킬 때에 사용되는 밀폐밀착력이 향상된 관체연결용 패킹에 관한 것이다.The present invention relates to a tubular connection packing having improved sealing strength, which is used when connecting ends of a tubular body and a tubular body to each other inside a tubular connector.

이를 좀 더 상세히 설명하면, 사다리꼴의 형상으로 형성되는 수밀패킹본체의 외면에 외면수밀수평접속링을 일체로 형성하고, 상기 수밀패킹본체의 내부에는 중앙절개홈을 하측으로 개방되게 형성하되, 상기 외면수밀수평접속링의 외주면에서 양측 가장자리에는 수밀돌띠와 수밀돌부를 각각 형성하고 이들 사이에는 만곡수밀접속돌부를 하나 이상 형성하여 밀폐밀착수밀패킹을 형성하며, 본 발명의 밀폐밀착수밀패킹을 관체의 환상요홈에 결합하여 관체의 내부에 삽입시키면 외면수밀수평접속링의 외주면에서 양측 가장자리에 각각 형성된 수밀돌띠가 외향으로 절곡되면서 수밀돌부와 접속되어 이중으로 밀폐력을 갖도록 하고, 이들 사이에 형성된 만곡수밀접속돌부가 연결관의 내주면과 접촉되어 압착되면서 팽창 억류되어 연결관의 내부면에 강력하게 밀착 및 지지되면서 수밀효과도 강화시킬 수 있도록 된 밀폐밀착력이 향상된 관체연결용 패킹을 제공하려는 것이다.
The watertight packing connecting member is formed integrally with an outer surface watertight horizontal connecting ring on an outer surface of a watertight packing body formed in a trapezoidal shape and a central cutout groove is formed to open downward inside the watertight packing body, The watertight horizontal connection ring is formed with watertight ridges and watertight portions on both sides of the outer circumferential surface thereof and one or more curved watertight connection protrusions are formed therebetween to form a tightly packed watertight packing. The watertight stone formed on both side edges of the outer peripheral surface of the outer watertight horizontal connection ring is folded outward to be connected to the watertight portion so as to have a double sealing force, The projecting portion comes into contact with the inner circumferential surface of the connecting tube and is compressed and attached to the inner circumferential surface of the connecting tube, Adhered to and not as a hermetically sealed so as to also enhance tight adhesion effect is intended to provide a better seal for tube connection.

통상적으로, 유체(하수)를 유통시키기 위해 유로를 형성하는 하수관, 집수관, 배수관등은 폴리에틸렌(PE:polyethylene), 폴리염화비닐(PVC:Poly Vinyl Chloride) 등의 합성수지재로 성형하고, 내관과 요홈이 형성된 외관을 일체로 접합 하여 형성된 이중벽관을 주로 사용하게 된다.Generally, a sewer pipe, a collecting pipe and a drain pipe forming a flow path for circulating a fluid (sewage) is formed of a synthetic resin material such as polyethylene (PE) or polyvinyl chloride (PVC) A double-walled tube formed by integrally joining outer tubes formed with recesses is mainly used.

상기 이중벽관에는 소켓, 이음관, 연결관 등과 같은 관 연결부재를 통해서 축방향으로 연장되며, 이때 관 연결의 수밀성을 보장하기 위해 이중벽관과 연결부재 사이에 패킹이 사용된다.The double wall tube extends in the axial direction through a pipe connecting member such as a socket, a connecting pipe or a connecting pipe, and a packing is used between the double wall pipe and the connecting member to ensure watertightness of the pipe connecting.

상기 종래의 패킹은 이중벽관의 요홈에 삽입되는 링형상의 패킹본체부와, 상기 패킹본체부의 외측단에서 이중벽관과 연결부재 사이에 위치되도록 직각되게 연장형성되며 내측면 또는 외측면에 둘레부를 따라 돌기가 돌출형성된 수밀연장부로 이루어져 있다.The conventional packing has a ring-shaped packing body portion inserted into a groove of a double walled pipe, and a pair of pipe-shaped body portions extending perpendicularly from the outer end of the packing body portion to be positioned between the double walled pipe and the connecting member, And a watertight extension portion in which a projection is protruded.

그러나 종래의 이중벽관들은 이중벽관의 요홈 간격이 패킹본체부의 폭보다 크게 되면 밀폐력이 떨어져 틈새로 하수가 누수되기 쉽고, 이중벽관의 요홈간격이 패킹본체부의 폭보다 작게 되면 패킹본체부를 삽입하는 데 어려움이 있다.However, in the conventional double wall pipes, if the spacing of the double wall pipes is larger than the width of the packing body portion, the sealing force tends to be leaked due to the sealing force, and if the spacing of the double wall pipe is smaller than the width of the packing body portion, .

보편적으로 관체를 접속할 때에는 패킹을 개입시켜 지지력과 밀폐력을 유지시키게 되는데, 종래의 패킹부재로서는 국내의 공개특허 공개번호 제10-1998-3129호(관체수밀접속용 패킹부재)와 등록실용신안 제20-205378호(관체수밀접속용 탄성고무링)와가 알려져 있다. 전자는 단면으로 보아 삼각형 형성된 각 삼각본체의 뿔에 브레이브를 형성하고, 후자는 평판형으로 된 본체의 외면 양단에 돌부를 각각 형성하여서 된 것으로서, 이들은 관체와 관체사이에 끼움하여 사용되므로 지지력과 밀폐력이 현저히 떨어지게 된다. Conventionally, as a conventional packing member, there have been proposed a packing member of Japanese Patent Application Laid-Open No. 10-1998-3129 (packing member for watertight connection of a pipe body) and a novelty 20 -205378 (elastic rubber ring for watertight connection to a pipe body) are known. The former is formed by forming a brave on the horn of each triangular body formed in a triangular shape and the latter is formed by forming a projection on both ends of the outer surface of the body of a flat plate type. Since these are used to be sandwiched between the body and the tube, Is greatly reduced.

또, 다른 종래의 이음관으로는 1999년 등록실용신안 제20-157456호가 알려져 있다.Another conventional coupling tube is known from 1999 Utility Model No. 20-157456.

이는 삽입되는 관을 협지할 수 있도록 관 삽입구를 절개하고 이 절개부를 가압하여 결합시킬 수 있도록 된 이음관을 제공하고, 단순 나사결합에 의한 가압접속구조에 의거 조립 시공이 용이하고, 교체 및 유지 보수가 용이한 이음관을 제공하고자, 관체를 내삽입할 수 있도록 적의의 직경을 갖으며 기밀 유지용 패킹을 갖는 이음관의 단부에 절개단부를 형성하여 이 절개단부를 가압하는 것에 의하여 관을 분기하거나 이을 수 있도록 된 이음관에 관한 구성이 개시되어 있다.This makes it possible to provide a joint pipe that can cut the tube insertion hole so as to hold the tube to be inserted and press the tube to join the tube, and it is easy to assemble the tube by the simple structure of the screw connection, It is necessary to form a cut end at the end of the joint pipe having an enemy diameter so as to insert the tube into the tube and to seal the tightening tube so that the tube is branched by pressing the cut end A structure related to the joint pipe is disclosed.

그러나, 상기 종래 기술에 따른 이음관은 이음관에 어떠한 가변구조가 구성되어 있지 않으므로 관 연결 시공 후 사후적으로 발생하는 연약지반에서의 부등침하, 열팽창에 의한 신축, 사하중 및 활하중에 의한 상재하중 등이 작용하는 경우 그 충격을 흡수할 수 없으므로 이음부분의 강성보다 큰 하중이 작용하는 경우 이음관 또는 관 부분에 파손이 발생하는 문제가 있다.However, since the joint pipe according to the related art has no variable structure in the joint pipe, it is possible to prevent uneven settlement in the soft ground, expansion and contraction due to thermal expansion, overload caused by dead load and live load, etc. The impact can not be absorbed. Therefore, when a load greater than the rigidity of the joint portion acts, there is a problem that breakage occurs in the joint pipe or the pipe portion.

이와 같은 문제를 해소하기 위하여 제안된 것으로는 특허등록 제10-0915524호(이중벽관이음관)가 알려져 있다.In order to solve this problem, Patent Registration No. 10-0915524 (a double-walled tubular sound tube) is known.

이는 관체와 접속관과의 사이에 이탈방지링이 구비되는 미끄럼방지링과 별도의 패킹을 구비하여서 된 것으로서, 상기 미끄럼방지링과 패킹은 본체링(또는 링관)의 내부면에 돌편을 형성하여 돌편이 관체의 외주에서 돌기와 돌기 사이에 형성된 홈에 유입되도록 된 것이다.This is because the anti-slip ring and the packing are provided with a protrusion on the inner surface of the main ring (or ring tube) And the slits are introduced into the grooves formed between the projections and the projections on the outer periphery of the tubular body.

그러나, 이는 미끄럼방지링과 패킹에 형성된 돌편을 형성하여 돌편이 관체의 외주에 형성된 홈에 유입되어 밀폐시키도록 되어 있으므로 밀폐능력이 현저히 떨어지고, 서로 접속되는 관체를 견실하게 구속시키지도 못하였다.However, this is because the slip-resistant ring and the protrusions formed on the packing are formed so that the protruding pieces are introduced into the grooves formed on the outer periphery of the tubular body to seal the tubular body, so that the sealing ability is significantly lowered and the tubular bodies connected to each other are not firmly restrained.

관체를 연결시키는 또 다른 종래의 것으로는 등록실용신안 제20-0416913호(관체연결용 패킹)가 알려져 있다. Another conventionally known method for connecting the tubular body is disclosed in Korean Utility Model Registration No. 20-0416913 (tubular connecting packing).

이(패킹)는 수직의 링형상으로 유지되는 패킹본체부의 외주에 수평으로 유지되는 수밀연장부를 수평으로 형성하되 패킹본체부의 내부 중앙에는 하측으로 개방된 절개홈을 형성하고 내면에는 날개편을 형성하며, 수평으로 유지되는 수밀연장부의 외면에 다수의 돌기를 형성한 것으로서, 패킹본체부가 관체의 외주에 형성된 외주돌테링 사이의 요홈에 결합되고, 수밀연장부의 외면에 형성된 돌기들이 연결관의 내부에 접촉되도록 된 것이다.The packing has a watertight extension portion horizontally held on the outer periphery of a packing body portion held in a vertical ring shape, a cutout groove opened to the lower side is formed at an inner center of the packing body portion, And a plurality of protrusions formed on the outer surface of the watertight extension portion held horizontally, wherein the protruding portions formed on the outer surface of the watertight extension portion are in contact with the inside of the connection tube .

그러나, 이는 패킹본체부의 내면에 형성된 날개편이 관체를 형성하는 외주돌테링과 접속되고, 수밀연장부의 외면에 형성된 돌기들이 연결관의 내부에 접속되도록 된 것이나, 이 역시 시간이 경과할수록 이동하는 유체의 충격에 의해 지지력과 밀폐력 및 밀착력이 떨어질 염려가 있다.
However, this is because the wing element formed on the inner surface of the packing body portion is connected to the outer circumferential surface ring forming the tube body, and the protrusions formed on the outer surface of the watertight extension portion are connected to the inside of the connector tube. However, There is a possibility that the supporting force, the sealing force and the adhesion force may be deteriorated by the impact.

본 발명은 상기와 같은 종래의 문제들을 해소할 수 있도록 개선된 밀폐밀착력이 향상된 관체연결용 패킹을 제공하려는 것이다.SUMMARY OF THE INVENTION It is an object of the present invention to provide a tubular connection packing improved in sealing adhesion so as to overcome the above-mentioned conventional problems.
