Description

플랜지 접속형 상수도관 이음 장치{APPARATUS FOR CONNECTING FLANGE TYPE WATER SUPPLY PIPE}Flanged Connection Water Pipe Fittings {APPARATUS FOR CONNECTING FLANGE TYPE WATER SUPPLY PIPE}

본 발명은 상수도관 이음 장치에 관한 것으로, 더욱 상세하게는 상수도관 사이의 수밀성을 확보하여 상수의 누출과 지하수의 침투를 효과적으로 차단할 수 있는 플랜지 접속형 상수도관 이음 장치에 관한 것이다.
The present invention relates to a water pipe fittings, and more particularly to a flange-connected water pipe fittings that can effectively prevent leakage of water and penetration of groundwater by securing watertightness between the water pipes.

일반적으로 가정 등에 상수를 공급하기 위한 상수관로는 다수의 상수도관이 이음되어 이루어진다.Generally, a plurality of water pipes are jointed with water pipes for supplying water to homes.

종래 상수도관의 연결구조로 등록특허번호 제0770167호가 있다.There is a connection structure of the conventional water pipe No. 0770167.

종래 상수도관의 연결구조는 관이 열융착되는 아답터와 연결되는 플랜지의 외측으로 돌출부와 홈부를 형성하고, 돌출부에서는 볼트와 너트를 서로 체결하는 연결구조를 제공하며 플랜지의 밀착면에 형성된 결합공면을 안쪽으로 경사지게 구성하여, 이 후 결합수단을 통해 결합공을 압박하면 결속력으로 경사진 결합공면이 상호 밀착되어 보다 안정적으로 플랜지를 고정할 수 있도록 하는 것이다.The connection structure of the conventional water pipe forms a protrusion and a groove on the outside of the flange which is connected to the adapter to which the pipe is heat-sealed, and the protrusion provides a connection structure for fastening the bolt and the nut to each other. It is configured to be inclined inward, and then press the coupling hole through the coupling means is to be in close contact with the inclined coupling surface by the binding force to be able to secure the flange more stably.

그러나 이러한 종래의 관 연결구조는 일정한 간격으로 다수개의 볼트를 결합하여 체결력을 전달하게 되므로, 볼트가 설치된 주변에서는 정상적으로 조임력이 전달되지만, 볼트의 사이에 있는 공간에서는 조임력이 정상적으로 전달되지 못하게 되므로 볼트가 설치되지 않은 사이의 공간에서는 조임력이 약해지는 결점이 발생하게 되므로 전체적으로 균일한 조임력을 제공할 수 없는 단점이 발생하게 된다.However, in the conventional pipe connection structure, a plurality of bolts are coupled at regular intervals to transmit a clamping force, and thus a tightening force is normally transmitted in the vicinity of the bolt, but a bolt is not normally transmitted in a space between the bolts. In the space between the installation does not have the disadvantage that the tightening force is weakened, the overall disadvantage that can not provide a uniform tightening force occurs.

그리고 조임력이 발생하지 않는 부분은 홈부로 형성되므로 취약한 결점이 발생하며, 플랜지의 사이에 삽입되거나 상수도관의 사이에 설치되는 고무링은 링 형태를 제공하게 되므로 링 형태의 면에서 강한 밀착력을 제공하는 것이 한계가 있어서 수밀을 유지하는 것이 불안정한 결점이 발생하게 된다.In addition, since the portion where the tightening force does not occur is formed as a groove, a weak defect occurs, and the rubber ring inserted between the flanges or installed between the water supply pipes provides a ring shape, thereby providing a strong adhesion in terms of the ring shape. There is a limit to this, which results in an unstable defect in maintaining watertightness.

또한, 볼트를 이용하여 너트를 회전시켜 조임력을 전달함에 있어서, 인력을 이용하여 조임력을 가하게 되므로 작업자에 따라서 조임력이 각기 다르게 제공되므로 균일한 조임력을 제공하는 것이 어렵고, 플랜지가 정상적으로 원주방향에서 균일하게 체결되었는지를 확인하는 것이 불가능하여 체결 여부를 정확하게 알 수 없는 결점이 있었다.In addition, in the transmission of the tightening force by rotating the nut using a bolt, the tightening force is applied by the manpower, so it is difficult to provide a uniform tightening force because the tightening force is provided differently according to the operator, the flange is normally uniform in the circumferential direction There was a flaw in which it was impossible to know exactly whether or not it was concluded.

또한, 볼트 머리부분과 너트를 통하여 조임력이 가해질 때 합성수지로 이루어진 부분에서 강도에 취약하므로 조임력으로 파손되는 결점이 발생하게 된다.In addition, when the tightening force is applied through the bolt head and the nut, the part made of synthetic resin is vulnerable to strength, so that a defect occurs due to the tightening force.

한편, 볼트와 너트를 결합하여 연결하는 플랜지를 상수도관의 외경에 결합하여 용접 연결하여 일체형으로 조립하게 되므로 생산된 상수도관과 플랜지를 용접 연결하기 위한 용접 연결작업을 별도로 수행해야 하는 것이어서 생산과정이 복잡해지는 결점이 발생하며, 상수도관의 외경보다 더 큰 외경을 갖는 플랜지가 돌출된 상태에서 보관 및 이동과 설치작업을 수행해야 하는 것이어서 이러한 과정에서 얇게 노출된 플랜지가 충격으로 쉽게 변형되거나 손상되어 사용이 어려운 결점과 함께, 상수도관의 생산 길이 양쪽에 플랜지를 연결하여 작업을 수행하지만, 상수도관의 일부분을 절단하여 연결작업을 수행해야 하는 경우에는 플랜지가 없어서 연결 작업을 수행하는 것이 매우 어려운 단점이 있었다.
On the other hand, since the flange connecting the bolt and nut by connecting to the outer diameter of the water supply pipe is welded and assembled together, it is necessary to separately perform the welding connection work for welding the produced water pipe and the flange. Complicated defects occur, and storage, movement, and installation work must be carried out while the flange having an outer diameter larger than the outer diameter of the water supply pipe is protruded. In this process, the thinly exposed flange is easily deformed or damaged by impact. With this difficult drawback, flanges are connected on both sides of the production line of the water supply line, but when it is necessary to cut a part of the water supply line to make the connection, it is very difficult to connect because there is no flange. there was.

제1,2상수도관(1,2)의 관이음측 단부에는 각각 제1,2외향 플랜지(1a,2a)가 형성되며, 제1,2외향 플랜지(1a,2a)에는 원주방향을 따라 일정 간격을 두고 다수의 체결공(1b,2b)이 형성된다.First and second outward flanges 1a and 2a are formed at end portions of the first and second water supply pipes 1 and 2, respectively, and the first and second outward flanges 1a and 2a are fixed along the circumferential direction. A plurality of fastening holes 1b and 2b are formed at intervals.

본 발명은 제1,2상수도관(1,2)의 제1,2플랜지(1a,2a)의 접속을 통해 제1,2상수도관(1,2)을 이음하는 것으로, 제1,2상수도관(1,2)을 따라 흐르는 상수가 제1,2플랜지(1a,2a)의 사이를 통해 누수되지 않고 반대로 지하수가 제1,2상수도관(1,2) 안으로 침투하지 않도록 패킹(10)과 덮개(20)가 갖추어진다.The present invention connects the first and second water conduits (1,2) by connecting the first and second flanges (1a, 2a) of the first and second water conduits (1,2). Packing 10 so that the constant flowing along the pipes 1 and 2 does not leak between the first and second flanges 1a and 2a and conversely the groundwater does not penetrate into the first and second water pipes 1 and 2. And cover 20 is provided.

패킹(10)은 제1,2상수도관(1,2)의 내주면에 밀착되어 제1,2플랜지(1a,2a) 사이를 패킹하는 제1패킹부(11), 제1,2플랜지(1a,2a)의 사이에 개재되는 제2패킹부(12) 및 제1,2플랜지(1a,2a)의 둘레부를 감싸는 한 쌍의 제3패킹부(13)로 구성되며, 천연고무, 합성고무 등을 재질로 한다.The packing 10 is in close contact with the inner circumferential surface of the first and second water conduits 1 and 2, and includes a first packing part 11 and a first and second flange 1a that seal between the first and second flanges 1a and 2a.
