본 고안은 강관과 합성수지관의 접속용으로 특히 적합한 관접속용 링패킹에 관한 것이다. 이 분야에 관련된 선행기술로서는 일본국 실개 소57-80783호, 동 60-67489호가 있다. 전자의 선행기술은 포켓부만으로 된 링패킹이고, 후자는 반원형 단면을 가진 링패킹을 적용하고 있다. 그러나 전자의 링패킹은 접속단 부근에 관계수의 걸림돌기가 끼어 걸리는 환상오목홈을 가진 강관과 강관과의 접속용으로는 유효하지만 그러한 강관과 접속단 부근에 환상오목홈을 부여하기 곤란한 합성수지관과의 접속용으로는 부적합하다. 한쪽을 강관에 끼우면 나머지 한쪽은 합성수지관을 끼워야 하는데, 합성수지관을 끼우는 부분의 내주면이 좁은 폭을 갖고 있어서 합성수지관을 수밀적으로 붙잡아주는 힘이 약한데다 강관과 합성수지관의 팽창계수가 달라 합성수지관에 수축변화가 왔을 때 링패킹이 그 수축변화에 능동적으로 따라 가지 못함으로써 틈이 벌어지고 이 틈으로 누압, 누수현상이 발생할 가능성이 농후하기 때문이다. 후자의 링패킹은 관의 접속단이 서로 겹친 경우에 적용하는 것이지 관계수와 관 접속용 수밀재로는 부적합하다. 따라서, 본 고안의 목적은 합성수지관의 외주면쪽으로 가해지는 관계수의 압박에 따른 밀착성이 우수하여 강관과 합성수지관과의 접속에서 큰 효과가 나타나는 관접속용 링패킹을 제공하는 것이다. 포켓부로 된 통상의 링패킹에 있어서, 본 고안은 링패킹의 한쪽 측면에서 외측으로 역테이퍼진 확개부를 연장 형성하여 합성수지관에 접촉면적을 넓힘과 동시에 압박력을 강화한 관접속용 링패킹을 제공한다.The present invention relates to a ring seal for pipe connection, which is particularly suitable for the connection of steel pipes and synthetic resin pipes. Prior arts related to this field include Japanese Patent Application Laid-Open No. 57-80783 and 60-67489. The former prior art is ring packing with only pockets, and the latter applies to ring packing with a semicircular cross section. However, the former ring packing is effective for connecting steel pipes with annular concave grooves in which the relative number of projections are caught near the connecting end, and synthetic resin pipes which are difficult to provide annular concave grooves near such steel pipes and connecting ends. It is not suitable for the connection of. When one side is inserted into the steel pipe, the other side has to insert the synthetic resin pipe. The inner circumferential surface of the portion in which the synthetic resin pipe is fitted has a narrow width, so that the force holding the synthetic resin pipe tightly is weak and the expansion coefficient between the steel pipe and the synthetic resin pipe is different. This is because ring packing does not actively follow the shrinkage change when a shrinkage change occurs, and there is a high possibility that a pressure leak or leakage phenomenon occurs due to the gap. The latter ring packing is applied when the connection ends of pipes overlap each other, and is not suitable for the relational coefficient and watertight material for pipe connection. Accordingly, an object of the present invention is to provide a ring packing for pipe connection which is excellent in adhesiveness due to the pressure of the relative water applied to the outer circumferential surface of the synthetic resin pipe and has a great effect in the connection between the steel pipe and the synthetic resin pipe. In the conventional ring packing of the pocket part, the present invention extends the reverse tapered extension from one side of the ring packing to provide the ring packing for the pipe which expands the contact area and strengthens the pressing force at the same time.
이하, 바람직한 실시예를 토대로 작성한 첨부도면에 따라 구체적으로 본 고안을 설명한다.Hereinafter, the present invention will be described in detail according to the accompanying drawings prepared based on the preferred embodiment.
제1도에 있어서, 금속제 엘보오(1)의 접속단에는 환상 오목홈(2)이 형성되어 있고, 합성수지관(3)의 접속단은 평관상태 그대로이다. 관계수(4)의 내주면 일측단에는 내향 지지턱(5)이 형성되어 있고, 타측단에는 짧은 받침턱(6)이 형성되어 있다. 내향 지지턱(5)은 엘보오(1)의 접속단 부근에 주어진 환상오목홈(2)을 걸어서 접속 및 역접속방향으로 다가서거나 물러날 수 없게 가두는 동시에 링패킹(7)의 포켓부(8)쪽 단면을 저지하여 엘로오(1)쪽으로 밀리지 않도록 지지하는 것이고, 받침턱(6)은 링패킹(7)의 확개부(9) 외측면을 저지하여 물러나지 못하게 하는 것이다. 내향 지지턱(5)의 안쪽 내주면은 확개단부(9)에 비해 외경이 큰 링패킹(7)의 포켓부(8)를 수용하기 알맞게 내경을 넓히고 그 외의 나머지 부분은 내경을 작게 형성한다. 이로써 관계수(4)의 내주면 단면은 2단이 된다. 제2도에 나타난 바와 같이, 링패킹(7)은 포켓부(8)의 일측에는 축방향으로 연장하여 확개부(9)로 한다. 확개단부(9)는 포켓부(8)에서 볼 때 역테이퍼져 있으며, 그 외경은 여기에 씌워지는 관계수 부위의 내경보다도 크게 형성하여 접속시 억압당하게 함으로써 합성수지관에 대한 접촉성을 강화하고, 길이도 그 부위에 해당하는 관계수와 함께 길게 형성하여 접촉면적으로 넓힌다. 접속은 다음과 같은 요령으로 실시한다.In FIG. 1, the annular recessed groove 2 is formed in the connection end of the metal elbow 1, and the connection end of the synthetic resin pipe 3 is a flat tube state. An inward support jaw 5 is formed at one end of the inner circumferential surface of the relational tree 4, and a short support jaw 6 is formed at the other end thereof. The inward support jaw (5) hangs the annular concave groove (2) given near the connection end of the elbow (1) and locks it so that it cannot be approached or retracted in the connecting and reverse connection directions, and at the same time the pocket portion of the ring packing 7 ( 8) is to prevent the end of the cross-section to be pushed toward the Elo (1), the supporting jaw (6) is to block the expansion of the outer side (9) of the ring packing (7) to prevent retreat. The inner inner circumferential surface of the inwardly supporting jaw 5 widens the inner diameter so as to accommodate the pocket portion 8 of the ring packing 7 having a larger outer diameter than the enlarged end portion 9, and the rest of the other portion forms a small inner diameter. As a result, the cross section of the inner circumferential surface of the relational coefficient 4 becomes two stages. As shown in FIG. 2, the ring packing 7 extends in the axial direction on one side of the pocket portion 8 to be an extension 9. The extended end 9 is reverse tapered when viewed from the pocket 8, and the outer diameter thereof is larger than the inner diameter of the relational part to be covered therein so as to be suppressed at the time of connection, thereby enhancing contact with the synthetic resin tube, The length is also formed long with the relational number corresponding to the part, and the contact area is widened. The connection is carried out as follows.
제1도에서, 엘보오(1)의 접속단에는 포켓부(8)를 씌우고 확개부(9)에는 합성수지관(3)의 접속단을 끼운다. 이 상태에서, 반쪽씩으로 나뉜 관계수(4)는 내향 지지턱(5)을 엘보오(1)의 환상오목홈(2)에 둘러 건다. 그리고는 양쪽 관계수(4)의 플랜지끼리 보울트-너트로 조인다. 관계수(4)가 조여들 때 확개부(9)는 탄력적으로 죄어들어 합성수지관(3)의 접속단 외주면에 강력한 힘으로 밀착된다. 확개부(9)의 내주면에 축방향으로 나란한 환상의 활지돌기를 부여하면 더욱 큰 밀착력을 얻을 수 있다. 이상 설명한 바와 같은 본 고안은 접속단 부근에 오목홈의 부여가 가능한 엘보오 등의 강관과 환상오목홈을 부여하기 곤란한 합성수지관을 수밀적으로 완성도 높게 튼튼히 접속할 수가 있다.In FIG. 1, the connection end of the elbow 1 is fitted with a pocket 8 and the extension 9 is fitted with a connection end of the synthetic resin tube 3. In this state, the relational number 4 divided into halves surrounds the inward support jaw 5 in the annular recess 2 of the elbow 1. Then, the flanges of both relational coefficients 4 are tightened with bolt-nuts. When the relational tree 4 is tightened, the extension portion 9 is tightened elastically and closely adhered to the outer circumferential surface of the connection end of the synthetic resin tube 3 with a strong force. If the inner peripheral surface of the extension part 9 is provided with the annular sliding protrusion parallel to the axial direction, a larger adhesive force can be obtained. As described above, the present invention can securely connect steel pipes such as elbows and the like that are difficult to provide annular concave grooves to provide a concave groove close to the connection end in a watertight and high degree of perfection.
