본 고안은 건물의 수도 배관용 이음관을 합성수지(P.P)관으로 사용함에 있어서, 수도배관의 이음관에 매입하는 너트관의 누수방지 구조에 대한 것이다.The present invention relates to a leak-proof structure of a nut pipe embedded in a joint pipe of a water pipe in using a pipe for a water pipe of a building as a synthetic resin pipe.

종래의 너트관은 그 내단면에 패킹홈을 빙둘러 요입 형성하여 이에 합성수지 패킹링의 내단을 끼워 결착한 다음 너트관을 합성수지이음관의 일단부내에 매입되게 성형하였는데, 이 경우에는 비록 이음관의 사출성형 과정에서 합성수지 패킹링의 외단이 이음관의 재질인 합성수지와 융착되어 일체화되기는 하지만 합성수지제인 패킹링의 내단과 금속제인 너트관의 패킨홈과의 접촉면은 일체화가 되게 밀착이 되지 않기 때문에 이들의 접촉면 사이에 틈이 발생된다.Conventional nut pipes are formed with a recess in the inner end of the packing groove, and the inner end of the synthetic resin packing ring is attached thereto, and then the nut pipe is formed to be embedded in one end of the resin joint pipe. In the molding process, the outer end of the synthetic resin packing ring is fused and integrated with the synthetic resin, which is the material of the joint pipe. There is a gap in between.

또한, 이러한 현상은 너트관 외면과 이음관의 접촉면에서도 발생하게 되어 결국 사용식 패킹링과 패킹홈의 접촉면 사이를 통해 누수가 되고 누수된 물은 너트관의 외면과 이음관 사이의 접촉면 사이를 통해 외부로 누수되었으며, 이에 따라 건물이 훼손되는 등의 문제점들이 있었다.In addition, this phenomenon also occurs in the contact surface between the nut tube and the joint pipe, which eventually leaks through the contact surface between the used packing ring and the packing groove, and the leaked water passes between the contact surface between the nut pipe and the joint pipe. There was a problem such as leaking to the outside, resulting in damage to the building.

따라서, 종래에는 합성수지 이음관이 널리 사용되지 못하고 가격이 비싼 동관을 주로 사용하였기 때문에 비용 부담이 가중되는 등 비경제적인 문제점들도 있었다.Therefore, in the past, synthetic resin joints were not widely used, and expensive copper tubes were mainly used, and thus, there were also uneconomical problems such as increased cost burden.

본 고안은 이러한 점들을 해결하기 위해 고안한 것으로, 너트관의 패킹홈에 합성수지제 패킹링은 그 내단을 결합하고, 그 외면측으로는 실리콘 고무등으로 만든 패킹링을 패킹홈에 완전히 들어가게 결합한 다음 패킹홈의 외단주연부를 내측으로 가압하여 절곡시켜 주므로 패킹홈에 끼워진 패킹링들이 압착되면서 패킹홈 내면에 서로 완강히 밀착 결합되도록 하였기 때문에 누수가 효과적으로 방지되도록 한 것이다.The present invention was devised to solve these points, and the packing ring made of resin is combined with the inner end of the packing pipe of the nut tube, and the packing ring made of silicone rubber etc. is completely inserted into the packing groove on the outer side. Since the outer periphery of the groove is pressurized to the inside to bend, the packing rings fitted in the packing grooves are pressed tightly to each other and tightly coupled to the inner surface of the packing grooves, thereby preventing leakage effectively.

이하, 본 고안의 실시예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

제 1 도 및 제 2a 도는 본 고안의 제 1 실시예를 보인 것으로서, 외주면에 수개의 돌출부(11)와 요입부(12)가 형성되게 가공하는 너트관(1)의 내단면에는 패킹홈(13)을 빙둘러 형성하여 이에 합성수지제 패킹링(2)은 내단부를 이 패킹링보다 폭이 좁게 실리콘 고무등으로 성형하는 패킹링(3)은 패킹링(2)의 내단부 외측면에 위치하게 각각 결합시켜 준 다음 패킹홈(13)의 외단주연부(13')를 내측으로 절곡되게 빙둘러 가압하여 줌으로써 상기 패킹링(2)(3)들이 압착되게 하여 줌과 동시에 패킹링(3)은 완전히 매입되어 외부로 노출되지 않게 구성한 것이다.1 and 2a show a first embodiment of the present invention, and a packing groove 13 is formed on an inner end surface of a nut pipe 1 for processing several protrusions 11 and recesses 12 to be formed on an outer circumferential surface thereof. ), And the synthetic resin packing ring 2 is formed so that the inner end of the packing ring 3 is narrower than the packing ring, and the packing ring 3 is formed on the outer end of the inner end of the packing ring 2. After the coupling, the outer peripheral portion 13 'of the packing groove 13 is pressed inward to be bent inward so that the packing rings 2 and 3 are compressed so that the packing ring 3 is completely compressed. It is built so that it is purchased and not exposed to the outside.

이와 같이 되는 본 고안은 내측으로 절곡되는 외단주연부(13')에 의해 패킹링(2)의 내단부와, 패킹링(3)이 패킹홈(13)의 내주면 내에서 완강히 압착이 되어 이들의 결합면 사이에 틈새가 발생되지 않게 됨과 동시에 제 3 도에서 보는 바와 같이 이음관(4)을 합성수지로 성형할 때 그 일단부에 너트관(1)이 매입되게 성형하면 노출된 패킹링(2)의 외단부는 이음관(4)과 동일 재질이므로 성형시 이들이 서로 융착이 되게 일체화되기 때문에 전혀 누수가 되지 않게 되는 것이다.The present invention as described above is the inner end portion of the packing ring (2) and the packing ring (3) by the outer peripheral edge portion 13 'bent inwardly firmly pressed in the inner peripheral surface of the packing groove (13) There is no gap between the mating surfaces, and at the same time, as shown in FIG. 3, when the joint pipe 4 is molded from synthetic resin, the nut pipe 1 is embedded at one end thereof to expose the packing ring 2 Since the outer end of the joint pipe (4) is the same material so that when they are integrated to be fused to each other will not leak at all.

한편, 제 2b 도는 종래 제품을 보인 것인데 이는 너트관(10)의 패킹홈에 합성수지제 패킹링(30)의 내단만을 결합시킨 것이므로 이 경우에는 패킹링(30)의 내단부가 상기 패킹홈 내면과 완강히 밀착되지 못하게 되어 이들의 결합면 사이에 틈새가 발생되며 이에 따라 사용시 누수현상이 발생되는 것이다.On the other hand, Figure 2b shows a conventional product, which is coupled only the inner end of the synthetic resin packing ring 30 to the packing groove of the nut pipe 10, in this case, the inner end of the packing ring 30 is firmly with the inner surface of the packing groove There is no close contact between the mating surface between them is generated and accordingly leak occurs when used.

또한, 제 4 도는 본 고안의 제 2 실시예를 보인 것으로서, 이는 너트관(1)의 패킹홈(13)내에 패킹링(2)(3)들을 끼운 다음 외단주연부(13')가 절곡시킨 것 이외에 너트관(1)의 외주면측에 별도의 패킹홈(13a)을 부설하고, 이에 실리콘 고무등으로 성형한 또다른 패킹링(3')이 내입되게 결합토록 한 것으로 이 경우에는 상기 패킹링(2)(3)이외에 패킹링(3')에 의해서도 누수가 차단되도록 하여 주므로 더욱 누수방지효과가 향상되게 한 것이다.In addition, Figure 4 shows a second embodiment of the present invention, which is inserted into the packing ring (2) (3) in the packing groove (13) of the nut pipe (1) and then bent by the outer peripheral portion (13 ') In addition, a separate packing groove 13a is provided on the outer circumferential surface side of the nut pipe 1, and another packing ring 3 'formed of silicon rubber or the like is inserted therein, in which case the packing ring In addition to (2) and (3), the leak is also blocked by the packing ring (3 '), thereby improving the leakage preventing effect.

이와같이 본 고안은 합성수지제 패킹링과 실리콘 고무등으로 성형하는 패킹링을 각각 패킹홈에 끼워준 다음이 패킹홈의 외단주연부를 내측으로 빙둘러 절곡되게 가압하여 이 외단주연부가 상기 패킹링을 가압시켜 압착되게 하여 주기 때문에 상기 패킹홈과 패킹링들의 접촉면 사이에 틈새가 발생되지 않고 밀착이 되게 하여주므로 사용시 전혀 누수가 되지 않게되는 장점이 있으며, 이에 따라 배관시 고가의 동관을 사용할 필요가 없어 비용도 대폭 절감되는 등 매우 유용한 고안이다.As such, the present invention inserts a packing ring made of a synthetic resin and a silicone rubber into the packing groove, respectively, and then presses the outer peripheral edge of the packing groove to bend inwardly, and the outer peripheral pressure presses the packing ring. Since there is a gap between the packing groove and the contact surface of the packing ring does not occur, there is an advantage that it does not leak at all when using, there is no need to use expensive copper pipe when piping, so the cost is also significantly It is very useful design such as saving.
