그리고, 후술할 너트부재(300)의 가압부(320)와 마주치는 지지부(230)의 일면 및 원추부(210)와 지지부(230) 사이의 외측면에는 오링(251)을 삽입하기 위한 오링삽입홈(250)이 형성된다. 따라서, 너트부재(300)와 페럴(200) 사이의 누설이 차단될 뿐만 아니라 결합몸체(100)와 페럴(200) 사이의 누설이 차단된다.
In addition, an O-ring insert for inserting an O-ring 251 into one surface of the support portion 230 and the outer surface between the cone portion 210 and the support portion 230 facing the pressing portion 320 of the nut member 300 to be described later. Groove 250 is formed. Therefore, not only the leakage between the nut member 300 and the ferrule 200 is blocked, but also the leakage between the coupling body 100 and the ferrule 200 is blocked.

상기 너트부재(300)는 너트몸체(310)와, 상기 너트몸체(310)의 끝단에 일체로 형성된 가압부(320)로 구성된다.The nut member 300 is composed of a nut body 310 and the pressing portion 320 formed integrally with the end of the nut body 310.

산업용배관(P)이 끼움된 페럴(200)이 결합몸체(100)의 경사부(121)에 삽입된 상태에서 너트부재(300)를 회전시킨다. 즉, 너트부재(300)의 너트몸체(310)를 결합몸체(100)의 제1나선부(112)에 결합시키기 위하여 일방향으로 회전시키면 너트부재(300)의 가압부(320)가 상기 페럴(200)의 지지부(230)를 가압하게 된다.The ferrule 200 in which the industrial pipe P is fitted is rotated in the nut member 300 in a state in which the ferrule 200 is inserted into the inclined portion 121 of the coupling body 100. That is, when the nut body 310 of the nut member 300 is rotated in one direction to be coupled to the first spiral portion 112 of the coupling body 100, the pressing unit 320 of the nut member 300 is connected to the ferrule ( The support 230 of the 200 is pressed.

이렇게 너트부재(300)의 가압부(320)가 페럴(200)의 지지부(230)를 가압하면 페럴(200)의 원추부(210)와 말단부(220)가 경사부(121)에 더욱 깊이 삽입된다. 동시에 페럴(200)의 말단부(220)가 경사부(121)에 눌려 오그라들게 됨으로써 상기 산업용배관(P)의 외측면을 가압한다.When the pressing portion 320 of the nut member 300 presses the support portion 230 of the ferrule 200, the cone portion 210 and the distal portion 220 of the ferrule 200 are inserted deeper into the inclined portion 121. do. At the same time, the distal end portion 220 of the ferrule 200 is pressed by the inclined portion 121 to pressurize the outer surface of the industrial pipe P.

좀 더 자세히 설명하면, 상기 페럴(200)의 원추부(210) 끝부분 외경과 여기에 연결되는 말단부(220)의 외경이 상기 경사부(121) 끝부분의 내경보다 크게 형성되기 때문에 페럴(200)이 결합몸체(100)의 경사부(121) 안쪽으로 점점 더 깊게 삽입되면 경사부(121)를 이루는 측면에 의하여 페럴(200)의 원추부(210)와 말단부(220)가 안쪽으로 강하게 압력을 받아서 오그라들게 되고, 이렇게 오그라들면 원추부(210)의 끝단과 말단부(220)의 내경이 작아져서 산업용배관(P)을 강하게 압박하게 된다. 바로 이러한 메커니즘으로 페럴(200)이 산업용배관(P)의 외측면에 견고하고 빈틈없이 고정되는 것이다.In more detail, the outer diameter of the end portion 220 of the cone portion 210 connected to the ferrule 200 and the outer diameter of the distal end portion 220 connected thereto are formed larger than the inner diameter of the end portion of the inclined portion 121. ) Is inserted deeper and deeper into the inclined portion 121 of the coupling body 100 by the side forming the inclined portion 121, the cone portion 210 and the distal end 220 of the ferrule 200 is strongly pressed inwards. Receiving is shrunk, and thus shrunk the inner diameter of the end and the distal end 220 of the cone portion 210 is to press the industrial pipe (P) strongly. It is this mechanism that the ferrule 200 is firmly and tightly fixed to the outer surface of the industrial pipe (P).

한편, 앞서 언급한 대로 상기 페럴(200)의 원추부(210)와 말단부(220) 사이에는 요홈부(240)가 형성될 수 있기 때문에, 만약 원추부(210)와 말단부(220) 사이에 요홈부(240)가 형성된 상태에서 너트부재(300)를 결합몸체(100)의 제1나선부(112) 외측면에서 회전시키면 너트부재(300)의 가압력에 의하여 요홈부(240) 부분이 안쪽으로 오그라들면서 산업용배관(P)의 외측면을 견고하게 파지하게 된다.
On the other hand, because the groove portion 240 may be formed between the cone portion 210 and the distal end portion 220 of the ferrule 200, as described above, if the yaw between the cone portion 210 and the distal end portion 220; When the nut member 300 is rotated on the outer side of the first spiral portion 112 of the coupling body 100 in the state where the groove portion 240 is formed, the recess portion 240 is moved inward due to the pressing force of the nut member 300. While gripping, the outer surface of the industrial pipe (P) is firmly gripped.
