본 고안은 수도관용 이음구에 관한 것으로서, 특히 수도관의 연결부를 씌워주는 이음구 본체와 수도관 사이에 밀봉부재를 삽입하고 상기 이음부 밀체와 나사결합하는 체결캡으로 구성된 수도관 이음구에 관한 것이다.The present invention relates to a water pipe fitting, and more particularly, to a water pipe fitting composed of a fastening cap inserting a sealing member between the water pipe main body and the water pipe covering the connection part of the water pipe and screwing the joint with the joint.
일반적으로 관의 이음구는 배관시 유체의 방향변화, 합수 또는 분기 지점이나 관의 연장을 위하여 관의 단부들을 서로 이어주는 연결수단으로 사용되는데, 그 이음구는 고압의 유압 및 물리적인 충격이 가해지는 반면에 경질의 합성수지재로 제조되기 때문에 쉽게 파손되는 문제점이 있었고, 특히 수도관은 용수의 지속적인 흐름에 의하여 끊임없는 맥동이 발생하여 이음부위에서 누수가 발생하거나 심한 경우에는 이음부위가 부분적으로 이완되는 문제점이 있었다.In general, the pipe joint is used as a connecting means connecting the ends of the pipe to change the direction of the fluid in the pipe, the joint or the branch point or the extension of the pipe, while the joint is subjected to high pressure hydraulic pressure and physical impact Because it is made of a hard synthetic resin material, there is a problem that it is easily broken. Especially, the water pipe has a problem of continuous pulsation caused by the continuous flow of water, causing leakage at the joint part or in case of severe loosening of the joint part. .
본 출원인은 상기의 문제점을 해결할 수 있는 내충격 수도관용 이음관을 창안하여 1994년 실용신안등록출원 제20311호로서 출원한 바 있다. 상기 고안은 제1도에 도시된 바와 같이, 이음구 본체(1)와 관(7)의 단부사이에 순차적으로 삽입되는 수팽창성고무(6)가 선단에 연결된 고무링(5), 내측스토퍼(4) 및 백스토퍼(3)와, 이음구 본체(1)에 나사결합되는 체결캡(2)으로 구성되어 있다.The present applicant has created a joint pipe for impact-resistant water pipes that can solve the above problems and filed in 1994 as Utility Model Registration Application No. 20311.

Next, when the fastening cap 2 is screwed into the fitting body 1, the inclined surface 2 ′ of the fastening cap 2 contacts the inclined surface 3 ′ of the back stopper 3 while the back stopper 3 is inward. The rubber ring 5, the inner stopper 4 and the back stopper 3 are pressed inward, and the rubber ring 5 is sealed between the tube 7 and the joint body 1 by the rubber ring 5, The protrusion 4a of the inner stopper 4 and the protrusion 3a of the back stopper 3 respectively penetrate to the outer circumferential surface of the synthetic resin pipe to some extent so as to exert the effect of preventing the pipe from being separated from the joint.
그러나, 상기 선출원 고안은 그 구조가 복잡할 뿐만 아니라 내측스토퍼 및 백스톱퍼가 탄성이 거의 없는 합성수지롤 제조되기 때문에 이음구 본체와 내측 스토퍼 및 백스톱퍼 사이의 밀봉이 완전히 이루어지지 않아 그 사이에서 누수가 발생하게 되는 문제점이 있었다.However, the design of the above-described application is not only complicated in structure, but also because the inner stopper and the back stopper are made of synthetic resin with little elasticity, the sealing between the joint body and the inner stopper and the back stopper is not completely made so that leakage occurs therebetween. There was a problem.
본 고안은 상기한 선출원 고안의 문제점을 해결하기 위하여 안출된 것으로서, 이음구 본체와 수도관 사이를 위치되는 고무링을 경도가 다른 재질로 길게 형성시켜 그 고무링의 일부에 스톱퍼가 접하도록 하여 밀봉효과를 향상시킴과 아울러 수도관 내의 유체의 흐름으로 인하여 발생하는 맥동을 흡수할 수 있는 수도관용 이음구를 제공하는데 그 목적이 있다.The present invention was devised to solve the problems of the above-mentioned prior application, the rubber ring located between the joint body and the water pipe formed of a material of different hardness to make the stopper contact the part of the rubber ring to the sealing effect The purpose of the present invention is to provide a water pipe fitting that can improve pulsation and absorb pulsations generated by the flow of fluid in the water pipe.

이하, 첨부도면을 참조하여 본 고안을 설명하면 다음과 같다.Hereinafter, the present invention with reference to the accompanying drawings.
본 고안은 수도관(10)의 연결부를 씌워주는 이음구 본체(11)와, 상기 이음부 본체(11)에 나사 결합되는 체결캡(40)과, 상기 이음구 본체(11)와 수도관(10) 사이에 위치되어 체결캡(40)이 조여짐에 따라 압착되는 고무링(20) 및 상기 고무링을 압착시키면서 수도관의 이완을 방지하는 스톱퍼(30)로 구성되어 있다.The present invention is a joint body 11 to cover the connection portion of the water pipe 10, the fastening cap 40 is screwed to the joint body 11, between the joint body 11 and the water pipe 10 Positioned is composed of a rubber ring 20 is pressed as the fastening cap 40 is tightened and a stopper 30 to compress the rubber ring while preventing the water pipe from being relaxed.
상기 고무링(20)은 전반부가 연질고무층(21)으로 형성되고 후반부는 경질고무층(22)으로 형성되어 있으며, 그 경질고무층(22)의 내주면은 확개부(23)가 형성되어 있다. 상기 스톱퍼(30)는 경질고무층(22)의 확개부(23)에 수용되는 몸체부(31)와 그 후단에 플랜지부(32)가 형성되어 있으며, 그 몸체부(31)에 금속제의 돌기(33)가 형성되어 있다. 또한, 상기의 체결캡(40)은 내향벽체(40a)가 형성되어 상기 스톱퍼(30)의 플랜지부와 접하도록 구성되어 있다.The rubber ring 20 has a first half formed of a soft rubber layer 21 and a second half formed of a hard rubber layer 22, and an inner circumferential surface of the hard rubber layer 22 has an expanded portion 23. The stopper 30 has a body portion 31 accommodated in the extension portion 23 of the hard rubber layer 22 and a flange portion 32 formed at the rear end thereof, and a metal protrusion (3) on the body portion 31. 33) is formed. In addition, the fastening cap 40 is configured such that the inward wall (40a) is formed in contact with the flange portion of the stopper (30).
이하, 본 고안의 작용효과를 설명하면 다음과 같다.Hereinafter, the operational effects of the present invention will be described.
본 고안의 이음구를 사용하여 수도관을 연결시키고자 하는 경우에는, 수도관(10)의 연결부위에 이음구 본체(11)를 씌우고 그 이음구 본체(11)와 수도관(10) 사이에 고무링(20)과 스톱퍼(30)를 위치시킨 다음 체결캡(40)을 이음구 본체(11)에 나사결합시켜 조여주면 체결캡(40)의 내향벽체(40a)가 스톱퍼(30)의 플랜지부(32)와 접하면서 스톱퍼(30)를 이음구 본체(11) 내부로 압박하여 고무링(20)이 압착되기 때문에 수도관과 이음구 본체 사이가 밀봉된다.When the water pipe is to be connected using the joint of the present invention, the fitting portion main body 11 is put on the connection portion of the water pipe 10, and the rubber ring 20 and the water pipe between the body 11 and the water pipe 10 Positioning the stopper 30 and then screwing the fastening cap 40 to the fitting body 11 to tighten the inward wall 40a of the fastening cap 40 while contacting the flange 32 of the stopper 30. Since the rubber ring 20 is compressed by pressing the stopper 30 into the fitting body 11, the water pipe and the fitting body are sealed.
이때, 고무링(20)은 이음구 본체(11)의 내측에 위치되는 전반부가 유연한 재질의 연질고무층(21)으로 형성되어 있기 때문에 연질고무층(21)이 수도관(10)과 이음구 본체(11) 사이에서 압착되어 탄성과 복원력에 의해 수밀성을 증대되므로 누수를 전면 차단하게 되고, 고무링(20)의 후반부는 비교적 단단한 재질의 경질고무층(22)으로 형성되어 있기 때문에 연질고무층(21)을 강하게 압착시킴과 아울러 그 경질고무층(22)의 확개부(23)에 스톱퍼(30)의 몸체부(31)가 수용되므로 경질고무층(22)이 스톱퍼(30)를 감싸주면서 외부면으로 압착되어 스톱퍼(30), 연질고무층(22) 및 이음구 본체(11)의 경계면이 밀착되어 수밀성이 더욱 증대되고 고무링(20)이 수도관내의 맥동을 흡수하여 진동을 방지하는 효과를 발생하게 된다.At this time, since the rubber ring 20 is formed of a flexible rubber layer 21 made of a flexible material, the first half of the rubber ring 20 is positioned between the water pipe 10 and the fitting body 11. The watertightness is increased by the elasticity and the restoring force, so that the leak is blocked entirely, and the second half of the rubber ring 20 is formed of the hard rubber layer 22 of a relatively hard material, thereby strongly compressing the soft rubber layer 21. In addition, since the body portion 31 of the stopper 30 is accommodated in the extension portion 23 of the hard rubber layer 22, the hard rubber layer 22 is pressed onto the outer surface while wrapping the stopper 30 to stop the stopper 30. In addition, the soft rubber layer 22 and the interface between the joint body 11 is in close contact with the watertightness is further increased, the rubber ring 20 absorbs the pulsation in the water pipe to produce an effect of preventing vibration.
또한, 스톱퍼(30)의 금속제 돌기(33)는 수도관(10)의 외주면을 파고들어 수도관의 이탈을 방지하는 기능을 수행하게 된다.In addition, the metal projection 33 of the stopper 30 is to penetrate the outer peripheral surface of the water pipe 10 to perform the function of preventing the separation of the water pipe.
이와 같이 본 고안은 수도관 연결부의 수밀성을 향상시키고 진동을 자체 흡수할 수 있는 잇점이 있다.As such, the present invention has an advantage of improving watertightness of the water pipe connection portion and absorbing vibration by itself.
