고압 배관용 파이프의 이음쇠{A joint of high pressure piping}A joint of high pressure piping

본 발명은 배관용 파이프의 이음쇠에 관한 것이다.  The present invention relates to a fitting of a pipe for plumbing.

이를 보다 상세하게 설명하면, 본 발명은 상·하수관이나 스팀관 등의 각종 고압 배관용 파이프의 이음쇠로서 파이프의 이탈 방지 기능과 수밀 기능이 있는 것이다.  In more detail, this invention is a fitting of various high pressure piping pipes, such as a water and sewage pipe, a steam pipe, and the like, and has the function of preventing the escape | separation of a pipe, and a watertight function.

종래에도 고압용 배관 파이프의 이음쇠가 다수 공지된 바 있었으나, 이러한 것들은 대체로 배관용 파이프에 조임너트와 고무패킹, 와샤, 스냅링 등을 차례로 끼운 다음 상기의 파이프를 이음쇠에 끼워 밀착시킨 후 조임너트와 상기의 이음쇠를 나사조임하여 체결하는 방식으로서, 이는 이음쇠의 구조가 복잡하고 부품 수가 많아 제조비용이 많이 들뿐만 아니라 체결 작업시간이 늘어나는 등의 문제점이 있었다.  Conventionally, many fittings of high-pressure plumbing pipes have been known, but these are generally inserted into piping pipes with tightening nuts, rubber packings, washers, snap rings, etc., and then the pipes are fitted to the fittings, and then the tightening nuts and the As a method of fastening by screwing the fittings, this has a problem such that the structure of the fitting is complicated and the number of parts is large, manufacturing costs are high, and the fastening work time is increased.

본 발명은 상기의 문제점을 해결하고자 안출하는 것으로서,   The present invention is to solve the above problems,

이의 발명요지는 이음쇠 몸체의 양쪽단부에 절단홈과 통공을 각각 형성하고, 상기 절단홈의 양측 외주면에 볼트 체결용의 플렌지를 형성하고 양측 내주면에 협지턱과 패킹 끼움홈 등을 형성하여 이 패킹끼움홈에 고무패킹을 부착한 것으로 상기 플렌지에 볼트를 끼워 너트로 나사조임함으로서 배관용 파이프가 협지턱에 압착 고정되게 한 것이다.   SUMMARY OF THE INVENTION The present invention forms cutting grooves and through holes at both ends of the fitting body, respectively, forming flanges for fastening bolts on both outer circumferential surfaces of the cutting grooves, and forming gripping jaws and packing fitting grooves on both inner circumferential surfaces thereof. The rubber packing is attached to the groove, and the bolt is inserted into the flange and screwed with a nut so that the pipe for the pipe is pressed and fixed to the squeezing jaw.

이를 도면에 의거하여 상세하게 설명하면 다음과 같다.  This will be described in detail with reference to the drawings as follows.

도1에서와 같이 금속재질로 된 원통형상의 이음쇠 몸체(1)의 구조는 양쪽 끝단부에 길이방향으로 절단홈(2)을 상하측에 대칭방향으로 형성하고 이 절단홈(2)의 양측단에 볼트체결용의 플렌지(3)를 각각 형성하며 상기한 플렌지(3)의 후측부에 상하로 각 2개씩의 통공(4)을 형성하며 상기한 이음구 몸체(1)의 내주면 선단부에는 협지턱(5)을 단속형으로 다수 형성하고 이 협지턱(5)의 내측 중심에는 걸림턱(8)을 형성하고 이 걸림턱(8)을 중심으로 하여 좌우 양쪽에 일정한 간격을 두고 패킹 끼움홈(6)을 형성하여 이 패킹 끼움홈(6)에 실리콘 또는 고무재질로 된 패킹(7)을 끼우되 이 패킹(7)의 주면에는 다수의 날개(7a)가 돌출 형성된 구조이다.  As shown in Fig. 1, the structure of the cylindrical fitting body 1 made of metal is formed in both ends of the cutting grooves 2 in the longitudinal direction in the symmetrical direction on the upper and lower sides, and on both sides of the cutting grooves 2, respectively. The flanges 3 for bolting are formed, respectively, and two through holes 4 are formed in the rear side of the flanges 3, respectively, up and down, and the pinching jaw 5 is formed at the tip of the inner circumferential surface of the joint body 1 described above. ) A large number of intermittent types are formed, and the locking jaw 8 is formed at the inner center of the clamping jaw 5, and the packing fitting grooves 6 are formed at regular intervals on both sides of the locking jaw 8. Forming and inserting the packing (7) made of silicon or rubber material in the packing fitting groove (6), the main surface of the packing (7) is a structure in which a plurality of wings (7a) protruding.

상기와 같이 구성된 본 발명의 실시예는 다음과 같다.  Embodiments of the present invention configured as described above are as follows.

상기한 이음쇠 몸체(1)에 배관용 파이프를 삽입할 경우, 상기 파이프의 외경이 상기 몸체(1)의 내주면의 패킹(7)에 비하여 다소 큼에 따라 상기 몸체(1)내의 중심부의 걸림턱(8)까지 연결용 파이프가 모두 삽입된 후 상기한 몸체(1)의 플렌지(3)의 체결공(3a)으로 체결용 볼트(9)를 끼워 넣고 타측에서 와셔(9b)를 개재한 너트(9a)로 나사조임함으로서 연결용 파이프가 상기한 협지턱(5)에 의해 긴밀하게 압착 체결되어 25kg/㎠이상의 고압에서도 유체의 누수를 방지하고 배관의 충격과 진동을 완벽하게 흡수할 수 있게 되는 것이다. 그리고 본 발명은 직선형 배관뿐만 아니라 T형이나 엘보(elbow)형에도 적용할 수 있는 것이다.  When inserting the pipe for the pipe into the fitting body (1), as the outer diameter of the pipe is slightly larger than the packing (7) of the inner circumferential surface of the body (1) the locking jaw of the central portion in the body ( 8) After all the connecting pipes are inserted, the fastening bolt 9 is inserted into the fastening hole 3a of the flange 3 of the body 1, and the nut 9a through the washer 9b through the other side. By tightening the screw to the connection pipe is tightly pressed by the clamping jaw (5) to prevent the leakage of fluid even at high pressure of 25kg / ㎠ or more to completely absorb the shock and vibration of the pipe. And the present invention can be applied to not only straight pipes but also T-shaped or elbow (elbow).

상기한 바와 같이 본 발명은 고압배관용 파이프의 이음쇠인바 몸체(1)의 선단부에는 절단홈(2)과 체결공(3a)이 있는 플렌지(3)를 형성하여 이에 연결파이프를 끼운 후 체결용의 볼트(9)와 너트(9a)로 나사조임함으로서 상기의 파이프를 긴밀하게 체결하는 것으로, 이는 구조가 간단하고 부품수를 절감하여 가격경쟁력이 있으며 현장시공 시에도 작업시간을 현저히 단출할 뿐만 아니라 특히 직선용 배관뿐만 아니라 T형이나 엘보형 배관에도 사용할 수 있어 매우 경제적인 효과가 있는 것이다.  As described above, the present invention forms a flange (3) having a cutting groove (2) and a fastening hole (3a) at the distal end of the fitting bar body (1) of the pipe for high-pressure pipe, and the connection pipe is inserted therein for fastening. Tightening the above pipes by screwing with bolts 9 and nuts 9a, which is simple in structure and reduces the number of parts, is cost-competitive and significantly shortens working time even in the field construction. It can be used not only for straight pipe but also for T type or elbow type pipe, so it is very economical.
