본 고안은 합성수지 파이프를 연결하는 관 연결장치에 관한 것이다. 종래 합성수지 파이프의 연결은 파이프의 연결 단부를 상대관의 외경에 맞도록 팽경시킴과 동시 그 팽경부에 또 다시 패킹링 삽입용 요홈을 확대 팽경시켜 그 패킹홈내에 패킹링을 삽입 개재하여 상대관의 접속단부를 팽경부내로 끼워넣어 연결되게하는 것이 일반적이었다. 전술의 종래 관연결장치는 연결단부가 관본체로부터 2단으로 확대 팽경되므로 연결부 주벽의 강도가 본체에 비해 상대적으로 약화되는 데다가 패킹삽입홈이 외부로 돌출되어 있게되어 파손되기 쉽고 패킹과 삽입홈이 비교적 단순하게 결합되어있기 때문에 수압에 의해 패킹링이 밀려나거나 밀착부위에서 변형이 생겨 누수가 발생하는 결점이 있었다.The present invention relates to a pipe connecting device for connecting a plastic pipe. Conventionally, the connection of a synthetic resin pipe is made to swell the connecting end of the pipe to match the outer diameter of the mating pipe, and at the same time, to expand and squeeze the packing ring inserting recess into the plunging part again and insert the packing ring into the packing groove. It was common to insert a connection end into a bulge part and to connect it. In the conventional pipe connecting apparatus, the connecting end is expanded and expanded in two stages from the tube body, so that the strength of the connection wall is relatively weaker than that of the main body, and the packing insertion groove is protruded to the outside, and the packing and the insertion groove are easily damaged. Due to the relatively simple coupling, the packing ring was pushed out due to hydraulic pressure, or deformation occurred at the contact part, causing a leak.
본 고안의 목적은 전술의 종래 결점을 개선하여 관연결부위의 강도를 저하시킴이 없이 수밀효과가 확실한 관연결장치를 제공하기 위한 것이며, 전술의 본 고안의 목적은 관연결단부에 일체로 부착 성형하고 내향 절곡 가능하게 형성한 패킹링과 팽경부내주면에 형성한 경사면 및 패킹자체의 유기적인 단면 구성에 의하여 달성될 수 있는 것인데, 이하 본 고안을 도면과 함께 설명하면 다음과 같다.The object of the present invention is to provide a pipe connection device with a watertight effect without reducing the strength of the pipe connection portion by improving the above-mentioned conventional drawbacks, the object of the present invention described above is integrally attached to the pipe end And it can be achieved by the organic cross-sectional configuration of the inclined surface and the packing itself formed on the packing ring and the bulge inner peripheral surface formed to be inward bent, when the present invention is described with reference to the drawings.
합성수지파이프(1)의 팽경된 연결부(2)의 내주면에 패킹링(3)을 개재하여 상대 파이프(1)를 접속하는 것에 있어서, 패킹링(3)을 중간에 절곡부(4)를 두고서 그 내단부측의 내외주면에 쐐기형의 돌조(5)(5')와 요홈(6) 및 경사면(7)과 요홈(8)을 갖도록 형성함과 함께 외단부측의 내외주면에 경사면(9)과 내면부(10)를 갖도록 형성하여 그 패킹링(3)의 내단부에 형성된 쐐기형의 돌조(5)(5')와 요홈(6)이 연결부(2)의 육조속에 매설되게 패킹링(3)을 일체로 연결부(2)에 부착함과 동시 연결부(2)내주면에 경사면(11)을 형성하여 관연결시 연결부(2)내주면에 일체로 부착된 패킹링(3)의 외단부를 내향절곡하여 사용하도록 구성한 것으로, 패킹링(3)과 연결부(2)의 일체 부착성형은 도면 제4도에서 보는 바와 같은 경사면(13)과 돌출부(14)를 갖는 성형만드렐(12)을 이용하여 성형하는바, 패킹링(3)의 내주면 요홈(8)에 만드렐(12)의 돌출부(14)를 끼운 것을 가열 연화상태로 있는 연결부(2)내에 삽입 성형하므로서 쐐기형 돌조(5)(5')와 요홈(6)주위로 육부가 충전 고착되게 하여 패킹링(3)의 내단부와 연결부(2)가 일체로 부착되게 성형할 수 있는 것이다.In connecting the mating pipe 1 to the inner circumferential surface of the inflated connection portion 2 of the synthetic resin pipe 1 via the packing ring 3, the packing ring 3 is provided with the bent portion 4 in the middle thereof. The inclined surface 9 is formed on the inner and outer circumferential surface of the outer end side while being formed to have the wedge-shaped protrusions 5, 5 ', the recess 6 and the inclined surface 7 and the recess 8 on the inner and outer circumferential surfaces of the inner end side. And an inner surface portion 10 so as to have a wedge-shaped protrusion (5) (5 ') and a recess (6) formed at the inner end of the packing ring (3) so as to be embedded in the inner tank of the connecting portion (2). 3) integrally attached to the connecting portion (2) and at the same time forming an inclined surface (11) on the inner peripheral surface of the connecting portion (2) inwardly the outer end of the packing ring (3) integrally attached to the inner peripheral surface of the connecting portion (2) It is configured to be bent and used, the integral attachment molding of the packing ring (3) and the connecting portion (2) by using a molding mandrel 12 having an inclined surface 13 and the protrusion 14 as shown in FIG. Molding The wedge-shaped protrusions 5 and 5 'are formed by inserting and inserting the projections 14 of the mandrel 12 into the inner peripheral surface recesses 8 of the packing ring 3 into the connecting portion 2 which is in a heat softened state. The inner part and the connecting part 2 of the packing ring 3 may be molded to be integrally attached by allowing the six parts to be filled and fixed around the groove 6.
이와 같은 본 고안은 평상시에는 파이프(1)의 연결부(2)에 일체로 부착되어 있는 패킹링(3)의 외단부가 연결부(2)의 단부에서 외측으로 노출되어 있게 되나 관연결시에 그 노출단부를 절곡부(4)를 중심으로 내향절곡하면 패킹링(3)의 외단부가 연결부(2)내측으로 뒤집히듯이 절곡되고 이때 연결부(2)내측으로 연결할 상대관의 연결단부(2')를 삽입하면 패킹링(3)의 내면부(10)가 경사면(7)과 연결부(2)의 내주 경사면(11)에 접촉하고, 패킹링(3)의 경사면(9)이 상대관 연결단부(2')외 주면에 밀착하게 되어 관의연결이 완료되는 바, 이렇게 연결된 관은연결부 사이에 개재된 패킹링(3)이 내면부(10)와 경사면(9)에 의해 경사면(7)과 경사면(11) 및 연결단부(2')외주면에 밀접된 쐐기의 형태를 구성하므로서 수압이 작용한다할지라도 패킹이 밀리거나 변형되는 일이 없게되어 누수를 방지할 수 있게 된다. 따라서 이와 같은 본 고안에 의하면 종래와 같이 패킹 삽입용홈을 무리하게 팽경시킬 필요가 없으므로 연결부 부분이 취약하게되거나 외부로 돌출되는 부분이 없게되어 연결부의 강도가 높아지게 되고 패킹링 자체도 밀리거나 변형되는 일이 없게되어 누수를 확실히 방지할 수 있는 개선된 효과를 나타내게 된다.The present invention is such that the outer end portion of the packing ring (3), which is normally attached to the connecting portion (2) of the pipe (1), is exposed to the outside at the end of the connecting portion (2), but the exposure at the time of pipe connection When the end is bent inward with respect to the bent portion 4, the outer end of the packing ring 3 is bent as if it is turned inside the connecting portion 2, and at this time, the connecting end 2 'of the mating tube to be connected inside the connecting portion 2 Inserting the inner surface portion 10 of the packing ring 3 in contact with the inclined surface 7 and the inner circumferential inclined surface 11 of the connecting portion 2, the inclined surface 9 of the packing ring 3 is the mating tube connecting end ( 2 ') the outer surface is in close contact with the connection of the tube is completed, the pipe connected in this way, the packing ring (3) interposed between the connecting portion between the inclined surface (7) and the inclined surface by the inner surface portion 10 and the inclined surface (9) (11) and the connecting end (2 ') by forming the shape of the wedge close to the outer peripheral surface, even if the hydraulic pressure acts so that the packing is not pushed or deformed A leak can be prevented. Therefore, according to the present invention, there is no need to forcibly squeeze the packing insertion groove as in the prior art, so that the connection part is not vulnerable or there is no protruding part, so the strength of the connection part is increased and the packing ring itself is pushed or deformed. This will result in an improved effect that will surely prevent leakage.
