도 1은 본 발명의 실시예에 따른, 무연공식 실리구조의 사시도이고, 도 2는 도 1의 조립단면도이다.1 is a perspective view of a lead-free silice structure according to an embodiment of the present invention, Figure 2 is an assembled cross-sectional view of FIG.

도면부호 20은 실리콘 패킹이다.Reference numeral 20 is a silicone packing.

상기 실리콘 패킹(20)은, 내주면에 원형의 주름을 형성하고 있고, 이 주름은 일정한 피치를 가지고 있다. 실리콘 패킹(20)은, 그 외주면에 양단부로부터 중앙으로 점증되는 일정한 기울기를 가지고 있다.The silicon packing 20 forms a circular wrinkle on the inner circumferential surface, and the wrinkle has a constant pitch. The silicon packing 20 has a constant inclination that increases from both ends to the center on its outer peripheral surface.

따라서 실리콘 패킹(20)은, 양단부로부터 중앙으로 증가되는 단면형태를 갖는 볼록한 원통형으로 구성된다.The silicon packing 20 is thus composed of a convex cylindrical shape having a cross-sectional shape that increases from both ends to the center.

상기 실리콘 패킹(20)의 양단부 내면에는 양측으로 알루미늄 보호관(11,12)의 단부가 밀착 조립되어 있다.End portions of the aluminum protective tubes 11 and 12 are closely assembled to both inner surfaces of both ends of the silicon packing 20.

상기 알루미늄 보호관(11,12)의 각각에는 제 1플랜지(30)와 제2플랜지(40)가조립되어 있고, 제1플랜지(30)와 제2플랜지(40)는 다수의 스터드볼트(34)로 연결되어 있다. 상기 스터드볼트(34)의 일단은 제1플랜지(30)에 고정되어 있고 그의 타단은 제2플랜지(40)를 삽통하여 너트(35)로 나사결합되어 있다.Each of the aluminum protective pipes 11 and 12 is assembled with a first flange 30 and a second flange 40, and the first flange 30 and the second flange 40 are connected to a plurality of stud bolts 34. It is connected. One end of the stud bolt 34 is fixed to the first flange 30 and the other end thereof is screwed with a nut 35 through the second flange 40.

상기 제1플랜지(30)는 상기 실리콘 패킹(20)의 일측 단부를 원형으로 감싸는 원통부(31)와, 실리콘 패킹(20)의 일측 단면을 지지하기 위한 압입환형턱(32)이 구비되어 있다.The first flange 30 is provided with a cylindrical portion 31 surrounding one end of the silicon packing 20 in a circular shape, and a press-fit annular jaw 32 for supporting one end surface of the silicon packing 20. .

상기 제2플랜지(40)는 상기 실리콘 패킹(20)의 타측 단부를 원형으로 감싸는 원통부(41)와, 실리콘 패킹(20)의 타측 단면을 지지하기 위한 압입환형턱(42)이 구비되어 있다. 또 제2플랜지(40)에는 상기 제1플랜지(30)와 스터드볼트(34)를 매개로 연결되기 위해 스터드볼트(34)의 나사부가 삽통하는 체결공(45)이 스터드볼트 (34)와 동수로 형성되어 있다.The second flange 40 is provided with a cylindrical portion 41 surrounding the other end of the silicon packing 20 in a circular shape, and a press-fit annular jaw 42 for supporting the other end surface of the silicon packing 20. . In addition, the fastening hole 45 through which the screw portion of the stud bolt 34 is inserted in the second flange 40 is connected to the first flange 30 and the stud bolt 34 by the same number as the stud bolt 34. It is formed.

따라서 도 1과 같이 상기 스터드볼트(34)의 나사부에 너트(35)를 조임방향으로 회전시키면, 너트(35)가 스터드볼트(34)에 체결되는 나사량이 증가되면서 제1플랜지(30)와 제2플랜지(40)의 대향 간격을 좁힐 수 있게 되어 있다.Accordingly, as shown in FIG. 1, when the nut 35 is rotated in the tightening direction of the threaded portion of the stud bolt 34, the amount of screw fastened to the stud bolt 34 increases with the first flange 30 and the first flange 30. It is possible to narrow the gap between the two flanges 40.

이와 같이 구성된 본 발명의 실링구조는, 일측의 알루미늄 보호관(11) 단부에 제1플랜지(30)를 삽입시켜 놓고, 타측의 알루미늄 보호관(12) 단부에 제2플랜지 (40)를 삽입시켜 놓고, 실리콘 패킹(20)의 양단부를 알루미늄 보호관(11,12)의 대향하는 단부에 끼워넣는다. 이때 제1플랜지(30)측 스터드볼트(34)의 나사부가 제2플랜지(40)의 체결공(45)에 삽통되어 있다.In the sealing structure of the present invention configured as described above, the first flange 30 is inserted into the end of the aluminum protective tube 11 on one side, and the second flange 40 is inserted into the end of the aluminum protective tube 12 on the other side. Both ends of the silicon packing 20 are inserted into opposite ends of the aluminum protective tubes 11 and 12. At this time, the threaded portion of the stud bolt 34 on the first flange 30 is inserted into the fastening hole 45 of the second flange 40.

이 상태에서 너트(35)를 스터드볼트(34)의 나사부에 체결시켜 조이게 되면,대향하는 양측 압입환형턱(32,42)이 실리콘 패킹(20)의 양단부를 중앙으로 압입시키게 되고, 결국 실리콘 패킹(20)의 단부가 탄력적으로 수축을 받아 알루미늄 보호관(11,12)의 외경과 실리콘 패킹(20)의 내면이 밀착하여 실링이 이루어진다.In this state, when the nut 35 is fastened by tightening the screw part of the stud bolt 34, opposing opposing press-fit ring jaws 32 and 42 press the both ends of the silicon packing 20 to the center, and eventually silicon packing. The end of the 20 is elastically contracted so that the outer diameters of the aluminum protective pipes 11 and 12 and the inner surface of the silicon packing 20 are in close contact with each other to seal.

즉, 본 발명은 상기 실리콘 패킹(20)의 양단부에 제 1플랜지(30)와 제2플랜지(40)를 조립함과 동시에 제1플랜지(30)측에 구비된 스터드볼트(34)를 제2플랜지 (40)에 삽입시켜 너트(35)로 가체결 한 후 상기 너트(35)의 체결량을 조절하여 상기 실리콘 패킹(20)의 내주면이 물리적 탄성력에 의해 상기 알루미늄보호관(11,12)의 결합부 외주면과 강제적으로 밀착되어 실링이 이루어진다.That is, the present invention assembles the first flange 30 and the second flange 40 at both ends of the silicon packing 20 and at the same time the second stud bolt 34 provided on the side of the first flange 30. After inserting into the flange 40 and pretightening with the nut 35, the coupling amount of the nut 35 is adjusted so that the inner circumferential surface of the silicon packing 20 is coupled to the aluminum protective tubes 11 and 12 by physical elastic force. It is in close contact with the outer circumferential surface and seal is made.

상술한 바와 같이 본 발명은, 종래의 연공작업에 대체하여 작업시간의 단축을 가져올 수 있고, 조립식 작업이므로 작업성이 용이하다. 또한 작업자의 건강에 해로움을 줄 수 있는 납을 사용하지 않으므로 부품의 재사용이 가능하고, 시험비용의 절감효과가 있다.As described above, the present invention can bring about shortening of working time in place of the conventional senior work, and is easy to work because it is a prefabricated work. In addition, since lead is not used, which may harm worker's health, parts can be reused and test cost can be reduced.
