Description
본 발명은 금속으로 구성된 잠금부분 및 연결부분을 가지며, 열가소성 합성수지로 형성된 관형부재를 상기 연결부분에 삽입하고, 이 관형부재를 열가소성 합성수지로 형성된 파이프 라인의 대응하는 연결부분에 끼워넣도록 하고, 상기 관형부재를 상기 연결부분에 클램핑한 연경장치에 관한 것이다.The present invention is characterized in that a tubular member having a locking portion and a connecting portion made of metal and formed of a thermoplastic synthetic resin is inserted into the connecting portion and the tubular member is fitted into a corresponding connecting portion of a pipeline formed of a thermoplastic synthetic resin, And a tubular member is clamped to the connecting portion.
파이프 라인은 분기 라인을 설치하거나 차단 공기포키시에 장착하기 위해, 또는 측정 존데(sonde)에 장착하기 위해 태핑된다. 작업을 완료한 후에는 관로의 개구를 폐쇄하여야 하는데, 예를 들어 분기관의 설치를 위해 이용되는 탭 단자에는 폐쇄 캡이 장착된다.The pipeline is tapped to install a branch line or to mount in a blocking air enclosure, or to mount on a measurement sonde. After completing the operation, the opening of the pipeline must be closed. For example, a closing cap is mounted on the tap terminal used for installing the branch pipe.
전술한 종류의 연결장칭, 예컨대 관 조인트가 유럽특허 EP-A-0561733 호에 공지되어 있다. 이 공지된 장치에서, 관형부재는 고정링(anchoring ring)에 의해 연결부분에 클램핑되어 있다. 그러나, 이 3개 부재로 조립되는 관 조인트의 제조 방법은 비용이 드는 단점이 있다. 게다가 시일 부분이 상기 고정링의 영역에서 상기 용접시에 가열되므로 상기 연결의 완전한 밀봉성이 제공되지 않는다.A connection neck of the kind described above, for example a pipe joint, is known from EP-A-0561733. In this known device, the tubular member is clamped to the connecting portion by an anchoring ring. However, the manufacturing method of the pipe joint assembled with these three members is disadvantageous in cost. In addition, since the seal portion is heated at the welding in the region of the stationary ring, no complete sealing of the connection is provided.
이런 종래 기술의 단점을 감안하여, 본 발명의 목적은 저비용으로 제조될 수 있으며, 전기용접후에도 연결부의 밀봉성이 보장되는 전술한 유형의 연결장치를 제공하는데 있다.In view of such disadvantages of the prior art, it is an object of the present invention to provide a connection device of the above-mentioned type, which can be manufactured at low cost and ensures the sealing of the connection even after electric welding.

상기 목저은, 잠금부분에 환형 홈을 형성함으로써 플랜지형 측벽을 형성하고, 관형부재의 일단부를 상기 환형 홈에 기워넣어 클램핑함으로써 달성된다.This is accomplished by forming a flange-like side wall by forming an annular groove in the locking portion and clamping one end of the tubular member by inserting it into the annular groove.
본 발명의 구성에 따르면, 관형부재에 압착된 플랜지형 측벽에 의해 액상 또는 가스상 매체 또는 경우에 따라서는 압력하에 정지되어 있는 매체에 대해 열결부재의 완전한 밀봉성이 얻어진다.According to the configuration of the present invention, the flange-like sidewalls pressed onto the tubular member achieve the complete sealing property of the heat-transfer member with respect to the liquid or gaseous medium or, if necessary, the medium which is stationary under pressure.
상기 관형부재는 상기 연결부분의 함입부에 배치되어 상기 환형 홈의 맞은편에 있는 정지면에 밀착되는 것이 바람직하다.Preferably, the tubular member is disposed in the recessed portion of the connecting portion and is in close contact with the stop surface opposite to the annular groove.
상기 연결장치는 황동, 탄소강 또는 함금강으로 만들어진다. 상기 관형부재의 재료는 파이프 라인 부분, 예컨대 그의 수용 부분의 재료에 맞춰진다. 재료로는 폴리올레핀계, 예를 들어 폴리에틸렌이 바람직하다.The connecting device is made of brass, carbon steel or steel. The material of the tubular member is adapted to the material of the pipeline portion, e.g., the receiving portion thereof. The material is preferably a polyolefin-based material, for example, polyethylene.
바람직한 제조 방법에 있어서, 상기 연결장치를 회전절삭가공에 의해 제조하고, 관형부재를 상기 연결부분 및 환형 홈 안에 삽입한다. 상기 연결장치의 원통형 부분의 선단주위에 합성수지를 사출성형하여 설치할 수도 있다. 다음에, 상기 플랜지형 측벽을 공지의 방법으로 관형부재에 압착시켜 매체의 밀봉성을 갖게 한다.In a preferred manufacturing method, the connecting device is manufactured by rotary cutting, and a tubular member is inserted into the connecting portion and the annular groove. A synthetic resin may be injection-molded around the tip of the cylindrical portion of the connecting device. Next, the flange-shaped sidewall is pressed onto the tubular member by a known method so as to provide the sealability of the medium.
관형부내는 플랜지형 측벽의 압착수에 회전절삭에 의해 원하는 최종 직경으로 되거나 또는 관형부재가 정확한 크기로 사출 성형될 수 있다.The inside of the tubular portion can be brought to a desired final diameter by rotary cutting on the number of squeezing of the flange-like side wall, or the tubular member can be injection molded to the correct size.
이 연결장치는 상이한 종류의 파이프 라인에 삽입될 수 있다. 예를 들어, 탭의 출구, 차단 공기포킷의 고정구, T-조인트, 또는 슬리브 개구에 직접 끼워넣을 수 있다. 상기 연결장치와 파이프 라인의 확실한 결합은, 접착 또는 용접 슬리브에 의한 용접에 의해 행할 수 있다.This connector can be inserted into a different kind of pipeline. For example, it can be inserted directly into the outlet of the tap, the fixture of the blocking air pocket, the T-joint, or the sleeve opening. The reliable connection between the connecting device and the pipeline can be achieved by welding with an adhesive or welding sleeve.
이하 첨부도면을 참조하여 본 발명의 바람직한 실시예에 대해 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.
열가소성 합성 수지로 된 파이프 라인의 관형 수용 부재 안에 삽입하기 위한 연결장치(10)는 수나사(12) 및/또는 암나사(14)가 있는 잠금부분(16)을 구비한다. 수나사(12)에는, 예를 들어 폐쇄 캡 또는 다른 차단 기관, 예를 들어 볼형 콕이 나사결합된다. 상기 암나사(14)는 폐쇄 용기를 수용하는데 이용되거나 또는 다른 파이프 라인과 결합될 수 있다. 상기 잠금부분(16)에 본래의 연결부분(18)이 연결되고, 이 연결부분은 파이프 라인의 관형 수용부분에 끼워넣을 수 있다. 상기 연결부분(18)은 함입부(20)를 구비하며, 이 합입부안에 열가소성 합성 수지로 형성된 관형부재(26)가 삽입된다.The connecting device 10 for insertion into a tubular receiving member of a pipeline of thermoplastic synthetic resin has a locking portion 16 with a male screw 12 and / or a female screw 14. To the male screw 12, for example, a closing cap or other blocking orifice, for example a ball cock, is threaded. The female screw 14 may be used to receive a closed container or be coupled to another pipeline. An original connecting portion 18 is connected to the locking portion 16, and this connecting portion can be fitted in the tubular receiving portion of the pipeline. The connecting portion 18 has an embedding portion 20 into which a tubular member 26 made of a thermoplastic synthetic resin is inserted.
상기 잠금부분(16)에 환형 홈(24)을 형성함으로써 둘레방향으로 플랜지형 측벽(22)이 돌출형성된다. 관형부재(26)는 일단부에서 환형 홈(24)에 끼워넣어지고, 함입부(20)에 의해 형성되는 정지면(21)에 타단부가 밀착된다. 이 환형 홈(24)의 개구푹(a)은 삽입되는 관형부재(26)의 벽 두께에 상응한다.By forming the annular groove 24 in the locking portion 16, the flange side wall 22 is protruded in the circumferential direction. The tubular member 26 is fitted into the annular groove 24 at one end and the other end is brought into close contact with the stop surface 21 formed by the recessed portion 20. The opening bore (a) of the annular groove 24 corresponds to the wall thickness of the tubular member 26 into which it is inserted.
제2도는 플랜지형 측벽(22)이 관형부재(26)에 압착되어 있는 사용상태에 있는 연결장치(10)가 되시되어 있다. 상기 연결부분(18)이 외경(d)은 관형부재(26)를 회전절삭함으로써 조절할 수 있다.Figure 2 shows the connecting device 10 in use in which the flange-like side wall 22 is pressed against the tubular member 26. The outer diameter d of the connecting portion 18 can be adjusted by rotationally cutting the tubular member 26.
실제의 삽입시에는 연결장치를, 예를 들어 전기용접 슬리브 안으로 삽입하고, 이 전기용접 슬리브에 의해 다른 파이프 라인과 연결한다. 이 연결부분(18)은 플랜지형 측벽(22)이 맞닿을 때까지만 상기 전기 용접 슬리브 안으로 이동될 수 있기 때문에, 긴밀한 접합을 형성하는 클램핑 영역이 용접시에 가열되지 않고, 긴밀한 접합이 유지된다.Upon actual insertion, the connecting device is inserted into, for example, an electrical welding sleeve, which is connected to another pipeline by the electrical welding sleeve. This connecting portion 18 can be moved into the electric welding sleeve only until the flange side wall 22 abuts, so that the clamping region, which forms a tight junction, is not heated at the time of welding, and tight bonding is maintained.
제3도에는 관형부재(26)가 삽입된 잠금부분(16)이 도시되어 있다. 상기잠금부분(16)과 관형부재(26) 사이의 연결 및 위치결정에 의해 유지가 더한층 확실해진다. 가이드면(16a)에는 윤곽 홈(27)에 제공된다. 상이한 단면형상을 가질 수 있는 이 윤곽 홈(27)에는, 이 홈에 대응하는 윤곽으로 형성된 상기 관형부재(26)의 돌출부(28)가 결합된다.FIG. 3 shows the locking portion 16 into which the tubular member 26 is inserted. By the connection and positioning between the locking portion 16 and the tubular member 26, the maintenance is further confirmed. And is provided in the contour groove 27 on the guide surface 16a. In this contour groove 27, which may have a different cross-sectional shape, the projection 28 of the tubular member 26 formed with the contour corresponding to this groove is engaged.
본 발명에 따른 연결장치는 저렴한 비용으로 제조될 수 있으며, 연결의 밀봉성이 용접후에도 보장된다.The connecting device according to the invention can be manufactured at low cost and the sealing of the connection is ensured even after welding.
