관 연결용 체결부재의 슬리브{Sleeve of the pipe connection for Members}Sleeve of the pipe connection member for members

본 고안은 관 연결용 체결부재의 슬리브에 관한 것으로, 좀더 상세하게는 가스관, 수관 등의 관을 밸브에 결합하거나 양쪽 관을 결합할 때 다중의 압착기능으로 실링 및 결합성을 향상시키도록 하는 관 연결용 체결부재의 슬리브에 관한 것이다.
The present invention relates to a sleeve of a fastening member for pipe connection, and more particularly, to a sleeve for connecting a pipe such as a gas pipe or a water pipe to a valve or both pipes, To a sleeve of a coupling member for coupling.

일반적으로 가스밸브, 에어콘 냉매관 등에 관을 연결하는 암수 체결부재에는 시일부재를 내입시키어 관 연결부분이 결합되도록 하고 있고 시일기능 및 결합을 높이도록 다양한 구조의 관 연결 체결부재가 제시되고 있다. 2. Description of the Related Art [0002] Generally, a male and female coupling members for connecting pipes to a gas valve, an air-refrigerant pipe, and the like are provided with pipe connecting members by inserting a sealing member.

그 일례로 선행기술로 실용신안등록출원 제20-2003-0033096호 "고압용 관연결구의 슬리브"가 제안된바 그 구조를 살펴보면,For example, in the prior art, a utility model registration application No. 20-2003-0033096 entitled " Sleeve for high-pressure pipe connector "has been proposed.

도 1에서와 같이, 압착너트(2)에 끼워지는 관(3)에 슬리브(4)를 끼운 상태에서 바디(1)에 나사결합으로 조여주면 슬리브(4)를 밀어주면서 압착되도록 하여 관(3)이 체결부재에 압착되도록 결합된 구조이다.1, when the sleeve 4 is inserted into the tube 3 fitted to the compression nut 2, the sleeve 4 is screwed to the body 1, ) Is coupled to the fastening member so as to be pressed.

그러나 압착너트(2)를 바디(1)의 외면에 나사결합이 되어 관(3)과 압착너트(2)의 접촉면적이 협소할 뿐만 아니라 압착너트(2)와 바디(1)의 사이에 슬리브(4)에 의해서만 결합되도록 하고 있어 슬리브(4)가 극히 미미한 일부라도 바디(1)와 압착너트(2) 및 관(3)에 확실하게 밀착되지 못할 경우 누출의 우려가 있고 더욱이 고압의 가스나 유체에 적용할 경우 더욱 위험성을 갖는 것이어서 충분한 안전성을 확보할 수 없는 문제점이 있다.
However, since the compression nut 2 is screwed to the outer surface of the body 1, the contact area between the tube 3 and the compression nut 2 is narrow, and the sleeve 2 is inserted between the compression nut 2 and the body 1, There is a risk of leakage if the sleeve 4 can not be surely brought into close contact with the body 1, the compression nut 2 and the tube 3 even if a part of the sleeve 4 is extremely small. Further, There is a problem that sufficient safety can not be ensured because it is more dangerous when applied to fluids.

본 고안은 상기한 종래의 문제점을 해결하기 위하여 제안된 것으로, 체결부재에 관을 결합할 때 슬리브의 전방은 경사부에 의한 압착과 동시에 후방은 패킹의 압착으로 밀폐되도록 하는 다중의 압착기능으로 실링 및 결합성을 향상시키도록 하는 관 연결용 체결부재의 슬리브를 제공함에 그 목적이 있다.

본 고안에 의한 체결부재(C)의 구성을 보면,In the configuration of the fastening member C according to the present invention,

한 측부에 결합홈(11)을 형성하는 바디(10)와, 상기 결합홈(11)에 내입되어 압착되는 슬리브(20)와, 상기 결합홈(11)에 연결관(40)이 끼워진 상태로 나사결합으로 체결하는 압착너트(30)를 포함하여 구성한다. A body 10 forming a coupling groove 11 on one side of the coupling groove 11 and a sleeve 20 inserted into the coupling groove 11 to be compressed and inserted into the coupling groove 11, And a compression nut (30) for fastening by screwing.

상기 슬리브(20)는, The sleeve (20)

전방부의 외면에 경사부(21)를 형성하여 바디(10)의 결합홈(11) 내측에 형성되는 경사면(12)에 경사부(21)가 접촉으로 압착너트(30)가 조여주면 경사부(21)가 내측으로 구부러져 연결관(40)에 압착되도록 한다. The inclined portion 21 is formed on the outer surface of the front portion so that the inclined portion 21 formed on the inner side of the engaging groove 11 of the body 10 is in contact with the pressing nut 30, 21 are bent inward to be compressed and attached to the connection pipe 40.

또한 후단부의 외측 모서리부에 외측곡면부(22)를 형성하면서 후단부의 내측으로 패킹 내입홈(23)을 형성하여 바디(10)에 체결되는 압착너트(30)에 의해 후단부가 눌러져 패킹 내입홈(23)에 끼워진 패킹(24)이 압착되어 연결관(40)에 밀착되도록 한 것이다.The outer side curved portion 22 is formed in the outer edge portion of the rear end portion and the packing inner groove 23 is formed inside the rear end portion so that the rear end portion is pressed by the compression nut 30 fastened to the body 10, 23 are pressed and adhered to the connection pipe 40.

상기 패킹 내입홈(23)의 후단부의 두께는 소정 두께로 형성하여 압착너트(30)의 조임시 내측으로 밀려 구부러질 수 있도록 형성하는 것이 바람직하다.It is preferable that the thickness of the rear end of the packing inner groove 23 is formed to be a predetermined thickness so that it can be bent and pushed inward when the compression nut 30 is tightened.

상기 압착너트(30)의 전단 외측부에 슬리브(20)에 형성한 외측곡면부(22)와 밀착되도록 동일 형상의 내측곡면부(31)를 형성하는 것이 바람직하다. It is preferable to form the inner curved surface portion 31 having the same shape so as to be in close contact with the outer curved surface portion 22 formed on the sleeve 20 at the front end outer side of the compression nut 30. [

상기 슬리브(20)의 중간부에 단턱부(25)를 형성하여 바디(10)의 내측 단턱부에 내입되는 패킹(50)을 압착하도록 하여 밀폐기능을 수행하도록 한 것이다.
A step portion 25 is formed at an intermediate portion of the sleeve 20 to press the packing 50 inserted into the inner step portion of the body 10 to perform a sealing function.

이와 같이 구성하는 본 고안에 대한 상호 작동상태를 설명하면 다음과 같다.The mutual operation state of the present invention will be described as follows.

바디(10)의 결합홈(11) 내측 단턱에 패킹(50)이 내입된 상태에서 압착너트(30)에 연결관(40)을 끼운 후 연결관(40)의 전방부에 슬리브(20)를 끼운 상태에서 연결관을 바디(10)에 삽입될 때까지 끼운 다음 압착너트(30)를 바디의 결합홈에 나사결합의 체결로 조임하면 압착너트(30)가 전진하면서 그 전방에 위치하는 슬리브(20)를 밀어주게 된다.The coupling tube 40 is inserted into the compression nut 30 in the state where the packing 50 is inserted into the inner edge of the coupling groove 11 of the body 10 and then the sleeve 20 is inserted into the front portion of the coupling tube 40 The coupling nut is inserted into the body 10 until the coupling nut is inserted into the body 10 and then the compression nut 30 is fastened to the coupling groove of the body by screw fastening so that the compression nut 30 advances and the sleeve 20).

이렇게 슬리브(20)가 전방으로 이동하게 되면 바디(10)의 결합홈(11) 내측에 형성되는 경사면(12)에 의해 슬리브(20)의 경사부(21)가 압착되면서 내측으로 구부러져 연결관(40)에 압착되어 물리는 1차적인 록킹 및 실링기능을 수행하고 압착너트(30)의 조임이 더 할수록 압착력은 높아지게 되는 것이며, When the sleeve 20 is moved forward, the inclined portion 21 of the sleeve 20 is compressed by the inclined surface 12 formed inside the coupling groove 11 of the body 10, 40 to perform a primary locking and sealing function, and the more the tightening of the compression nut 30 is, the higher the compression force is,

동시에 압착너트(30)가 조임으로 전진할 때 슬리브(20)의 후단부가 눌러져 구부러지면 패킹 내입홈(23)에 끼워진 패킹(24)이 전후방향으로 압착되어 연결관(40)에 압착되는 2차적인 실링기능을 수행하게 되는 것이다.At the same time, when the rear end of the sleeve 20 is pressed and bent when the compression nut 30 advances by tightening, the packing 24, which is fitted in the packing inner groove 23, is compressed in the forward and backward direction, Thereby performing a sealing function.

또한 압착너트(30)의 조임으로 바디(10)의 내측에 내입되는 패킹(50)을 압착하게 되므로 또 다른 밀폐기능을 수행하게 되는 것이다. Further, since the packing 50 which is inserted into the inside of the body 10 is squeezed by the tightening of the compression nut 30, another sealing function is performed.

이상과 같이, 본 고안은 압착되는 슬리브(20)에 의하여 다중의 압착기능으로 록킹 및 실링기능을 대폭적으로 향상시키어 신뢰성을 높일 수 있는 것이다.As described above, according to the present invention, the locking and sealing function can be greatly improved by the multiple pressing function by the sleeve 20 to be pressed, thereby enhancing the reliability.
