본 고안은 삽입식 관 이음쇠에 관한 것으로서, 본인의 선 실용신안등록출원 제86-7559호의 개량고안이다.The present invention relates to an insertion pipe fitting, which is an improvement plan of the prior utility model registration application No. 86-7559.
본 고안에서 관 이음쇠라 함은 이음관내의 수밀패킹에서 내향하여 돌출된 밀착부의 상면으로 관 내부의 수압이 가해져서 패킹의 밀착부와 관끝의 수밀시트가 압접되게 구성된 삽입식 관 이음쇠를 말하며, 이러한 관 이음쇠의 접속방법을 보면 관의 끝부분이 이음쇠내 수밀패킹의 밀착부를 확장하면서 삽입시키는 것인데, 이와 같은 종래관 이음쇠의 이점은 수밀을 유지한 상태에서 온도변화에 따른 관 길이의 팽창 수축운동을 허용할 수 있는 점이고, 결점으로는 관이 이음쇠로부터 이탈될 우려가 있으므로 관의 고정수단을 별도로 구성해야 하는 외에 관을 접속할때 내부의 패킹이 쭈그러지는 등 본래의 자세가 변형되는 것이다.In the present invention, the pipe fitting refers to an insert-type pipe fitting configured to press the watertight sheet of the packing and the watertight sheet at the end of the pipe by applying water pressure inside the pipe to the upper surface of the tight fitting portion projecting inward from the watertight packing in the fitting pipe. In the connection method of the pipe fitting, the end of the pipe is inserted while expanding the tight contact portion of the watertight seal in the fitting. The advantage of the conventional pipe fitting is that the expansion and contraction movement of the tube length according to the temperature change while maintaining the watertight This is an allowable point, and the drawback is that the tube may be separated from the fitting, so the fixing means of the tube must be separately configured, and the original posture is deformed when the tube is connected.
따라서 본인의 선출원 제86-7559호에서는 이와 같은 점들을 해결하기 위해 요철면, 레이퍼 등의 형성된 고정부재를 조임밴드로서 조여지기 구성하고, 수필패킹을 이음관내 고정턱에 끼워지게 구성하여 관이 이음쇠에서 이탈되지 않게 하면서 관의 신축운동을 허용하게 된 것이고, 관의 삽입시에는 내부의 수밀패킹이 쭈그러지지 않게 하였으나, 조임밴드를 조여주기 위한 별도의 수단을 필요로 하게 되고, 이때문에 이음관 내외를 개통하는 구멍을 갖게 되며 또, 이를 폐쇄하기 위한 캡이 필요하게 되는 등의 불편이 지적된다. 본 고안은 이러한 불편을 해소하기 위해 안출한 것으로써, 이를 첨부도면에 의거 상세히 설명하면 다음과 같다.Therefore, in my application No. 86-7559, in order to solve these points, the fixing member formed by the uneven surface, the raper, etc. is tightened as a tightening band, and the essay packing is configured to be fitted to the fixing jaw in the joint pipe. The expansion and contraction of the tube was allowed while the fitting was not detached, and the watertight packing of the tube was not crushed when the tube was inserted. However, a separate means for tightening the tightening band is required. The inconvenience of having a hole for opening the inside and outside of the tube, and the need for a cap to close it is pointed out. The present invention has been devised to solve this inconvenience, it will be described in detail based on the accompanying drawings as follows.
내향돌출된 밀착부(1)를 갖는 수밀패킹(2) 두개를 원통형 이음관(3) 좌우에 나누어 내장되고 이러한 수밀패킹(2)이 이음관 내부 두개의 턱(4)사이에 끼워지는 관 이음쇠에 있어서, 이음관내에 고리모양의 고정부재(12)를 내장하되, 고정부재에는 관(A)의 주벽에 접속되는 내면의 요철면(13), 이음관 외단의 내향가압턱(14)에 대응된 외측의 테이퍼(15), 외면의 종돌조(16) 및 이중돌조의 접속되며 이음관 내벽면의 탄성체 충진부재(17)의 내면에 접속되는 강판대(18) 및 고정부재 주벽면의 홈(19)을 형성하고, 수밀패킹(2)의 몸체 내주벽면(2')에는 통수공(20)을 갖는 고리모양의 판상부재(21)를 부착시킨 구성이다.Two watertight packings (2) having inwardly contacted contact portions (1) are built into the cylindrical joint pipe (3) left and right, and the watertight packing (2) is fitted between two jaws (4) inside the pipe. In the fitting pipe, a ring-shaped fixing member 12 is incorporated in the fitting pipe, and the fixing member corresponds to the uneven surface 13 of the inner surface connected to the main wall of the pipe A, and the inward pressing jaw 14 of the outer pipe. Grooves of the steel plate stand 18 and the fixed member main wall surface, which are connected to the inner surface of the elastic filling member 17 of the inner wall of the joint pipe, 19), and the annular plate-like member 21 having a water hole 20 is attached to the inner circumferential wall surface 2 'of the watertight packing 2.
본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention is as follows.
관(A)는 이음관(3)의 한쪽입구에서 밀어 끼운다.The pipe A is pushed in at one inlet of the joint pipe 3.
이때 관(A)는 고정부재(12)를 강제로 벌리면서 통과하고 수밀패킹(2)의 밀착부(1)를 팽창시키면서 삽입되므로 수밀패킹(2)과 관(A)은 밀접상태로 접속된다.At this time, the tube A is inserted while forcibly opening the fixing member 12 and inflating the contact portion 1 of the watertight packing 2 so that the watertight packing 2 and the pipe A are closely connected. .
판상부재(21) 는 상기한 접속공정에서 수밀패킹 (2) 이 구겨져 형태변경되는 것을 방지하며 접속된 후 밀착부(1)는 상부에 수압이 가해져서 관(A)상부에 압접되며, 수밀패킹(2)의 몸체 내주벽면(2')도 통수공(20)을 통하여 가해지는 수압으로 이음관 내벽에 압접된다.The plate member 21 prevents the watertight packing 2 from being crumpled and changed in shape in the above connection process. After the plate member 21 is connected, the close contact part 1 is pressed against the upper portion of the pipe A by applying water pressure to the upper part. The body inner circumferential wall surface 2 'of (2) is also press-contacted to the inner wall of the fitting pipe by the hydraulic pressure applied through the water passage 20.
관(A)의 이음관(3)에 접속되면 요철면(13)을 갖는 고정부재(12)는 충진부재(17)의 탄성가압력 강판대 (18)의가압력에 의하여 관(A)외 주벽에 고정된다.When it is connected to the joint pipe 3 of the pipe A, the fixing member 12 having the uneven surface 13 is connected to the outer wall of the pipe A by the pressing force of the elastic pressure steel plate 18 of the filling member 17. It is fixed.
그러나 관(A) 이 신축되면 수밀을 유지한채로 관(A)과 수밀패킹(2) 및 고정부재 외벽면의 종돌조(16)와 강판대(18)사이에는 동시에 미끄럼이 발생되어 관의 길이 방향 신축운동을 허용하게 되며 관(A)을 이음관(3)외부에서 당기면 이때에는 고정부재(12)의 테이퍼(15)가 가압턱(14)에 가압됨에 따라 고정부재(12)와 관(A)의 밀착력은 증대되고 이때 고정부재(12)가 가압턱(14)에 걸려 관(A)의 이탈이 방지되는 것이다.However, when the tube (A) is stretched, sliding is simultaneously generated between the tube (A), the watertight packing (2), and the longitudinal projection (16) and the steel plate (18) of the outer wall surface of the fixing member while maintaining the watertightness. When the tube (A) is pulled out of the joint pipe (3), the taper (15) of the fixing member 12 is pressed against the pressing jaw (14). ), The adhesion is increased and the fixing member 12 is caught by the pressure jaw 14 to prevent the separation of the pipe (A).
또 홈(19)은 고정부재(12)를 이음관 내에 조립할때 쉽게 굽혀지는 작용을 하기 위한 것이다.In addition, the groove 19 is to bend easily when the fixing member 12 in the fitting pipe.
상기한 바와 같이 본 고안은 관길이의 신축운동을 허용하면서 관이 이음관에서 이탈됨이 방지되고 접속시에 수밀패킹이 구겨짐을 방지함과 동시에 별도의 조임수단 및 폐쇄수단이 필요치 않게 된 효과가 있다.As described above, the present invention has the effect of preventing the pipe from being separated from the joint pipe while allowing the expansion and contraction movement of the pipe length, preventing the watertight packing from being wrinkled at the time of connection, and eliminating the need for a separate tightening means and a closing means. have.
