[

상기 슬라이딩 차단판(55)은 상부면 중앙에 형성된 너트부(56)가 슬라이딩 밸브 하우징(50)에 장착된 나선축(53)에 체결되어, 나선축(53)을 어느 한 방향으로 돌리면, 슬라이딩 차단판(55)이 슬라이딩 밸브 하우징(50)에서 인출되고, 나선축(53)을 반대 방향으로 돌리면, 슬라이딩 차단판(55)이 슬라이딩 밸브 하우징(50)으로 인입된다. A nut 56 formed at the center of the upper surface of the sliding barrier plate 55 is coupled to a spiral shaft 53 mounted on the sliding valve housing 50. When the spiral shaft 53 is rotated in one direction, The blocking plate 55 is drawn out of the sliding valve housing 50 and the spiral shaft 53 is turned in the opposite direction.

상기와 같이 구성된 본 발명에 따른 부단수 할정자관은, 도 2에 도시된 것처럼, 체크 밸브 하우징(30)에 슬라이딩 밸브 하우징(50)을 연결하고, 분기관(20)의 플랜지부(24)에 천공기(70)를 장착한다. 이후, 도 3에 도시된 것처럼, 천공기(70)의 커터(75)를 내려, 커터(75)로 상수도관(WP)을 천공하게 된다. 2, the sliding valve housing 50 is connected to the check valve housing 30 and the flange portion 24 of the branch pipe 20 is connected to the check valve housing 30, The perforator 70 is mounted. 3, the cutter 75 of the perforator 70 is lowered, and the water pipe WP is pierced with the cutter 75. Then, as shown in Fig.

이후, 보수 작업, 분기 작업 등과 같은 상수도관 작업이 완료되면, 도 4에 도시된 것처럼, 커터(75)를 천공기(70) 내의 원위치로 상승시킨 후, 슬라이딩 밸브 하우징(50)에서 슬라이딩 차단판(55)을 인출하여, 슬라이딩 차단판(55)으로 분기관(20)의 중공부(22)를 차단하게 된다. 여기서, 슬라이딩 차단판(55)이 슬라이딩 밸브 하우징(50)에서 인출될 때, 슬라이딩 차단판(55)이 체크 밸브 하우징(30)의 밸브 플레이트(40)를 밀게 되어, 슬라이딩 차단판(55)에 의해 밸브 플레이트(40)가 힌지핀(42)을 중심으로 도 4의 화살표(44) 방향으로 각회전됨으로써, 체크 밸브 하우징(30)의 외측 개구부(33)가 자동으로 개방되고, 슬라이딩 차단판(55)이 체크 밸브 하우징(30)의 외측 개구부(33), 밸브실(31) 및 내측 개구부(32)를 통해 분기관(20)의 중공부(22)를 차단하게 된다.4, after the cutter 75 is raised to the home position in the perforator 70, the sliding barrier plate 50 is slid in the sliding barrier plate 50 55 are drawn out and the hollow portion 22 of the branch pipe 20 is blocked by the sliding blocking plate 55. When the sliding blocking plate 55 is drawn out of the sliding valve housing 50, the sliding blocking plate 55 pushes the valve plate 40 of the check valve housing 30, The valve plate 40 is rotated about the hinge pin 42 in the direction of the arrow 44 in Figure 4 so that the outer opening 33 of the check valve housing 30 is automatically opened, 55 cut off the hollow portion 22 of the branch pipe 20 through the outer opening 33 of the check valve housing 30, the valve chamber 31 and the inner opening 32.

이후, 도 5에 도시된 것처럼, 슬라이딩 차단판(55)이 분기관(20)의 중공부(22)를 밀폐한 상태에서, 분기관(20)의 플랜지부(24)에서 천공기(70)를 분리하고, 분기관(20)의 플랜지부(24)에 마감뚜껑(80)을 수밀되게 결합한다.5, when the sliding block plate 55 seals the hollow portion 22 of the branch pipe 20, the perforator 70 is pulled out from the flange portion 24 of the branch pipe 20 And the finishing lid 80 is tightly coupled to the flange portion 24 of the branch pipe 20.

이와 같이, 본 발명은 천공 작업후, 마감뚜껑(80)을 분기관(20)의 플랜지부(24)에 수밀되게 장착할 수 있어, 천공 작업과 마감 작업 사이의 플러깅 작업을 생략할 수 있다. As described above, according to the present invention, after the drilling operation, the finishing lid 80 can be mounted to the flange portion 24 of the branch pipe 20 in a watertight manner, so that the plugging operation between the drilling operation and the finishing operation can be omitted.

이후, 도 6에 도시된 것처럼, 나선축(53)을 돌려 분기관(20)의 중공부(22)를 차단하고 있는 슬라이딩 차단판(55)을 슬라이딩 밸브 하우징(50)으로 인입하면, 밸브 플레이트(40)가 자중에 의해 힌지핀(42)을 중심으로 화살표(47)와 같은 반시계 방향으로 각회전됨으로써, 밸브 플레이트(40)가 체크 밸브 하우징(30)의 외측 개구부(33)를 차단하게 되어, 체크 밸브 하우징(30)에서 슬라이딩 밸브 하우징(50)을 분리하여도, 상수도관(WP)의 물이 체크 밸브 하우징(30)의 외측 개구부(33)를 통해 누수되는 것을 방지할 수 있게 된다. 이때, 상수도관(WP)에 작용하는 수압이 밸브 플레이트(40)에도 가해지게 됨으로써, 밸브 플레이트(40)가 체크 밸브 하우징(30)의 외측 개구부(33) 둘레에 강하게 압착된다.6, when the sliding block plate 55, which blocks the hollow portion 22 of the branch pipe 20 by turning the spiral shaft 53, is drawn into the sliding valve housing 50, The valve plate 40 rotates about the hinge pin 42 in the counterclockwise direction as indicated by the arrow 47 by its own weight so that the valve plate 40 blocks the outer opening 33 of the check valve housing 30 The water in the water pipe WP can be prevented from leaking through the outer opening 33 of the check valve housing 30 even if the sliding valve housing 50 is detached from the check valve housing 30 . At this time, the water pressure acting on the water supply pipe WP is also applied to the valve plate 40, so that the valve plate 40 is strongly pressed around the outer opening 33 of the check valve housing 30.

더 나아가, 도 6에 도시된 것처럼, 체크 밸브 하우징(30)에서 슬라이딩 밸브 하우징(50)을 분리하고, 체크 밸브 하우징(30)에 마감판(95)을 장착한 상태에서, 보조 가압수단(60)의 조절축 부재(62)를 이용하여 승하강 너트(64)를 가이드 홈(63)을 따라 내림으로써, 승하강 너트(64)가 밸브 플레이트(40)를 가압하게 되어, 밸브 플레이트(40)가 외측 개구부(33)의 둘레면에서 들뜨는 것을 보조적으로 방지하게 된다.6, in a state in which the sliding valve housing 50 is detached from the check valve housing 30 and the finishing plate 95 is mounted on the check valve housing 30, the auxiliary pressing means 60 The lifting nut 64 pushes the valve plate 40 and the valve plate 40 is moved downward along the guide groove 63 by using the adjusting shaft member 62 of the valve plate 40, Thereby preventing the outer opening 33 from being lifted from the peripheral surface.

이와 같이, 본 발명에 따른 부단수 할정자관은 상부 할정자관(10)의 분기관(20)에 체크 밸브 하우징(30)이 일체로 형성되고, 체크 밸브 하우징(30)의 밸브실(31)에 밸브 플레이트(40)가 배치되며, 밸브 플레이트(40)의 상단부가 힌지핀(42)에 의해 밸브실(31)에 장착됨으로써, 밸브 플레이트(40)에 의해 외측 개구부(33)가 자동으로 개폐될 수 있어, 체크 밸브 하우징(30)의 외측 개구부(33)를 개폐하는 구조가 매우 간단하고, 효율적이며, 생산 비용을 절감할 수 있고, 슬라이딩 차단판(55)에 의해 분기관(20)이 차단됨으로써, 상수도관 천공 작업후 분기관(20)의 플랜지부(24)에 마감뚜껑(90)을 수밀되게 장착할 수 있어, 상수도관 천공 작업에 따른 플러깅 작업을 생략할 수 있으며, 밸브 플레이트(40)에 의해 슬라이딩 차단판(55)을 포함하는 슬라이딩 밸브 하우징(50)을 분리할 수 있어, 시공 작업 비용을 절감할 수 있는 장점이 있다.
The check valve housing 30 is formed integrally with the branch pipe 20 of the upper purifier pipe 10 and is connected to the valve chamber 31 of the check valve housing 30 The valve plate 40 is disposed and the upper end of the valve plate 40 is attached to the valve chamber 31 by the hinge pin 42 so that the outer opening 33 is automatically opened and closed by the valve plate 40 The structure for opening and closing the outer opening 33 of the check valve housing 30 is very simple and efficient and the production cost can be reduced and the branch pipe 20 is blocked by the sliding blocking plate 55 It is possible to mount the finishing lid 90 in a watertight manner on the flange portion 24 of the branch pipe 20 after the water pipe drilling operation so that the plugging operation due to the drilling of the water pipe can be omitted, The sliding valve housing 50 including the sliding blocking plate 55 is removed So that the cost of construction work can be reduced.
