Description

삽입식 이중수밀 이음관{Insertting type double contacting joint}Insertion type double contacting joint

본 발명은 상수도관이나 가스관 등의 관(pipe) 연결시에 사용되는 삽입식 이중수밀 이음관에 관한 것이다.The present invention relates to an insert-type double watertight joint pipe used for connecting pipes such as water pipes and gas pipes.

수도관이나 가스관 등을 본 발명의 삽입식 이중수밀 이음관의 내부중앙턱까지 삽입하면 패킹 내경부의 물갈퀴(리플)들에 의해 상기한 삽입관이 본체와 긴밀한 1차 수밀구조가 되고, 다시 너트로 나사 조임하면 와샤가 오링을 압착하여 오링과 관이 다시 2차 수밀 구조가 되며, 와샤가 본체와 밀접하게 될수록 스토퍼와 너트 경사면의 슬라이딩에 의해 스토퍼가 내측으로 조여지면서 관을 압착하여 고압상태에서도 관의 이탈을 방지하게 되는 것이다.When the water pipe or the gas pipe is inserted into the inner middle jaw of the insert double watertight joint pipe of the present invention, the insertion pipe becomes a primary watertight structure in close contact with the main body by the water webs (ripples) of the inner diameter of the packing. When the screw is tightened, the washer presses the O-ring, and the O-ring and the tube become the second watertight structure.The closer the washer is to the main body, the more the stopper is tightened inward by the sliding of the stopper and nut slope, and the tube is crimped. This will prevent the departure of.

종래의 이음관들은 크게 두 종류로 나눌 수 있는데, 그 하나는 스토퍼와 와샤 가까이에 압착형 패킹이 위치한 기계식 이음관으로서, 이는 너트의 조임으로 패킹을 축방향으로 강하게 압착하여 수밀상태를 이루고 또한 스토퍼가 관을 압착하는 방식이나, 이는 패킹을 압착하는 과정에서 스토퍼내경이 먼저 줄어들면서 관을 잡 고 패킹 방향으로 강하게 끌고 들어가는 폐단이 있는 것으로 이는 배관의 길이방향 치수의 변화를 야기할 뿐만 아니라 양단부가 구속된 시공 상황에서는 어느 한쪽도 끌고 들어오지 못하므로 패킹을 누를 수 없어 수밀상태에 치명적인 결함이 있으며, 두 번째는 이음관에 관을 삽입하고 이음관의 외경을 강력한 압착기로 축관하는 프래스식 이음쇠로서, 이는 프레스 장비의 문제로 인해 정량 압착이 되지 않아 누수되는 문제와 숙련공이 아니면 장비사용이 어려워 패킹부 원주를 수직으로 정확히 압착하지 못하며, 하자 발생시 해체가 불가능함으로서 이음부의 양단을 절단하고 다시 2개소의 이음부를 형성하여야 하는 등의 문제점이 있었다.Conventional joint tubes can be classified into two types, one of which is a mechanical joint tube in which a crimping packing is located near the stopper and the washer, which is tightly axially pressed by the nut to form a watertight state and also a stopper. In the process of compressing the packing, there is a closed end in which the stopper inner diameter is reduced first and the tube is pulled strongly in the packing direction while the packing is pressed, which not only causes a change in the longitudinal dimension of the pipe, There is a fatal defect in the watertight state because the packing cannot be pressed because no one can drag in the constrained construction situation. The second is a plastic fitting that inserts the pipe into the pipe and condenses the outer diameter of the pipe with a strong press. This is a problem of leaking due to the problem of press equipment, If it is not a drill hole, it is difficult to use the equipment, and the circumference of the packing part cannot be exactly pressed vertically, and when a defect occurs, it is impossible to disassemble it, so that both ends of the joint part must be cut and two joint parts must be formed again.

본 발명은 상기의 문제점을 해결하고자 안출한 것으로서 이를 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been made to solve the above problems will be described in detail based on the drawings as follows.

도1에서와 같이 이음관 본체(1)의 내주면 중간에는 걸림턱(2)이 형성되고, 상기 몸체(1)의 양쪽단부는 다소 두께가 두껍게 형성하되 이의 내주면에는 요입형으로 된 패킹홈(3)을 안쪽에 형성하고 이 내주면의 바깥쪽에 오링(5)을 삽입하는 오링삽입부(1a)를 형성하며, 양쪽단부의 외주면에 돌출부(4)를 형성하되 이 돌출부(4)의 바깥쪽에는 너트(8)를 삽입할 수 있는 나사산부(1b)를 형성하고 상기한 돌출부(4)와 나사산부(1b) 사이에는 인디케이터(9)를 삽입할 수 있는 공간을 형성한 구조이다. A locking jaw 2 is formed in the middle of the inner circumferential surface of the fitting pipe main body 1 as shown in FIG. 1, and both ends of the body 1 are formed to have a somewhat thicker thickness. ) And an O-ring inserting portion (1a) for inserting the O-ring (5) on the outer side of the inner circumferential surface, and forming protrusions (4) on the outer circumferential surface of both ends, but the nut on the outside of the protrusion (4) The threaded portion 1b into which the 8 can be inserted is formed, and a space for inserting the indicator 9 is formed between the protrusion 4 and the threaded portion 1b.

그리고 상기한 본체(1)의 내측선단부에 형성된 오링(5)과 오링삽입부(1a) 및 와샤(6)를 제거한 형태로 된 별도의 이음관본체(20)를 구성할 수도 있다.In addition, the O-ring 5 and the O-ring inserting portion 1a and the washer 6 formed on the inner end portion of the main body 1 may be configured with a separate joint tube body 20.

본 발명은 패킹과 스토퍼를 분리시켜 수밀능력을 일정하게 하며 패킹은 이중구조로 되어 수밀성이 향상됨으로서 외부공기나 오염물질의 침투를 방지하고 스토퍼의 잇빨을 중앙부에 집중시켜 관의 이탈을 방지할 뿐만 아니라 본 발명은 내진설계를 함으로서 지진이나 천재지변시에도 이탈되지 않고 고압의 수밀성을 유지하며, 본체 나사부와 너트사이에 조임상태를 나타내는 유색으로 된 인디케이터(indicator)를 설치하여 현장 작업시에 시공성을 향상시키며 또한 본 발명은 일체형 구조로 되어 있어 시공이 간편하며, 특히 기존제품보다 얇고 크기가 작아 생산가를 낮출 수 있으므로 매우 실용적이고 경제적인 효과가 있는 것이다.The present invention separates the packing and the stopper to make the watertight capacity constant and the packing has a double structure to improve the watertightness, thereby preventing the penetration of external air or pollutants and concentrating the stopper's teeth in the center to prevent the tube from falling out. However, the present invention maintains the high-pressure watertightness without being separated from earthquake or natural disaster by earthquake-resistant design, and installability during field work by installing colored indicators indicating the tightening state between the main thread and the nut. In addition, since the present invention has an integrated structure, the construction is simple, and in particular, it is thinner and smaller in size than the existing product, so that the production cost can be lowered.

상기와 같이 구성된 본 발명은 시공현장에서 사용하고자 할 경우에는, 먼저 상기 이음관 본체(1)의 양쪽단부의 내주에 형성된 패킹홈(3)에 패킹(7)을 삽입하되 상기 패킹(7)의 내주측에는 다수의 물갈퀴(7a)가 형성되되 이 물갈퀴(7a)가 상기 본체(1)의 중앙부를 향하도록 하여 패킹홈(3)에 삽입 장착하고, 본체(1) 외주면에는 인디케이터(9)를 삽입한 다음 본체(1)에 삽입되는 관(pipe)(미도시)의 선단부에는 오링(5), 와샤(6), 스토퍼(7) 및 너트(8)를 삽입한 후 이 관(미도시)을 상기 이음관 본체(1)의 좌우측에서 삽입하여 본체(1)의 내주면 걸림턱(2)까지 삽입하면 상기한 패킹(7)의 내주측에 형성된 다수의 물갈퀴(7a)에 의해 강력한 1차수밀구조가 되고, 이어서 상기한 너트(8)를 조이면 와샤(6)가 상기 오링(5)을 압착하여 오링(5)과 관(미도시)이 일체화되면서 2차 수밀을 하게 되며, 그리고 와샤(6)가 본 체(1)의 선단부와 접하게 되어 스토퍼(10)와 너트(8)의 경사면이 완만한 슬라이딩구조로 되어 너트(8)의 회전력에 이해 더욱 강력하게 관을 잡아주는 힘이 가해지며 특히 내경부관을 잡아주는 이빨부(8a)를 종래와 달리 중앙부에 집중적으로 배치함으로서 힘의 분산을 막고 상기의 집중된 이빨이 강력하게 조임으로서 관을 수밀하게 압착하며 상기 스토퍼(10)가 내경방향으로 조여지면서 관을 긴밀하게 압착함에 따라 고압상태에서도 상기 관의 이탈을 방지하게 되는 것이다.When the present invention configured as described above is intended to be used in a construction site, the packing (7) is inserted into the packing groove (3) formed on the inner circumference of both ends of the joint pipe body (1) of the packing (7) A plurality of webs 7a are formed on the inner circumferential side, and the webs 7a are inserted into the packing groove 3 so that the webs 7a are directed toward the center of the main body 1, and the indicator 9 is inserted into the outer peripheral surface of the main body 1. The O-ring (5), washer (6), stopper (7) and nut (8) are inserted into the front end of the pipe (not shown) inserted into the main body (1). Inserted from the left and right sides of the joint pipe main body 1 and inserted into the inner circumferential surface locking jaw 2 of the main body 1, a strong primary watertight structure by a plurality of webs 7a formed on the inner circumferential side of the packing 7 Then, when the nut 8 is tightened, the washer 6 compresses the O-ring 5 to integrate the O-ring 5 and a tube (not shown), thereby forming a second watertight seal. And the washer 6 comes into contact with the front end of the main body 1, so that the inclined surface of the stopper 10 and the nut 8 has a gentle sliding structure, so that the tube can be more powerfully understood by the rotational force of the nut 8. In particular, the tooth portion 8a, which holds the inner neck tube, is concentrated in the center, unlike the conventional one, to prevent the dispersion of the force, and the concentrated teeth are tightly tightened to tightly squeeze the tube and the stopper ( As 10) is tightened in the inner diameter direction, the tube is tightly pressed to prevent the tube from being separated even under high pressure.

그리고 현장 작업시에 상기의 인디케이터(9)를 너트(8) 앞쪽에 장착함으로서 너트(8)를 조울 때는 상기 인디케이터(9)가 보이지 않을 때 까지만 조이면 시공이 완료되게 하여 조임의 정도와 조임량을 규격화할 수 있으며 특히 종래의 이음관과 달리 본 발명은 구조가 간단하고 일체형으로 되어 있어 시공작업이 용이하다.In the field work, the indicator 9 is mounted on the front of the nut 8 so that when the nut 8 is tightened, it is only tightened until the indicator 9 is invisible so that the construction is completed. In particular, unlike the conventional joint pipe, the present invention has a simple structure and an integrated structure, thereby facilitating construction work.

그리고, 오링(5)과 와샤(6) 및 오링삽입부(1a)가 없는 구조의 별도 이음관 본체(20)는 품질상 차이가 없으며 시공작업이 더욱 편리할 뿐만 아니라 외부의 화학적부식분위기를 차단함으로서 패킹(7)의 노화를 방지할 경우 원가를 절감시킬 수 있는 것이다.And, the o-ring (5) and washer (6) and the separate joint pipe body 20 of the structure without the O-ring insert (1a) has no difference in quality and is more convenient in construction work, as well as blocking the external chemical corrosion atmosphere If you prevent the aging of the packing (7) will be able to reduce the cost.
