This is for the movable member 40 to prevent the movable member 40 from being lifted from the valve body 20 by the hydraulic pressure, so that water leaks into the hollow portion 21 of the valve body 20.

이와 같이 본 발명에 따른 수도관 동파 방지장치가 수전(100)에 설치되면, 수도관(110)에 연결된 수전(100)에서 텐션조절부재(70)의 중공부(71), 마개(50)의 중공부(52) 그리고 가동부재(40)의 물공급구멍(44)을 통해 원통형 하우징(10)과 밸브 바디(20) 사이에 형성된 공간(30)으로 물이 공급되어, 상기 공간(30)에 물이 채워지게 된다. When the water pipe freeze protection device according to the present invention is installed in the faucet 100, the hollow portion 71 of the tension control member 70, the hollow portion of the stopper 50 in the faucet 100 connected to the water pipe 110 Water is supplied to the space 30 formed between the cylindrical housing 10 and the valve body 20 through the water supply hole 44 of the movable member 40, and water is supplied to the space 30. Will be filled.

그리고, 원통형 하우징(10)과 밸브 바디(20) 사이에 형성된 공간(30)의 부피가 작아, 동절기에 수도관(110)에 채워진 물 보다 상기 공간(30)에 채워진 물의 양이 적기 때문에 수도관(110) 보다 공간(30)에 채워진 물이 먼저 얼게 된다. In addition, since the volume of the space 30 formed between the cylindrical housing 10 and the valve body 20 is small, the amount of water filled in the space 30 is less than that of the water pipe 110 in winter, so that the water pipe 110 ), The water filled in the space 30 is frozen first.

상기 공간(30)에 채워진 물이 얼게 되면, 얼음의 부피가 물의 부피보다 크기 때문에 얼음이 밸브 바디(20)의 결합구멍(25)에 끼워진 가동부재(40)의 결합돌기(43)를 밀어 올림으로써, 가동부재(40)가 위로 상승하게 되어, 밸브 바디(20)의 중공부(21)를 막고 있던 가동부재(40)의 개폐돌기(42)가 위로 상승되어, 가동부재(40)의 개폐돌기(42)와 밸브 바디(20)의 중공부(21) 사이에 틈새가 발생하게 된다. When the water filled in the space 30 is frozen, the ice pushes up the engaging projection 43 of the movable member 40 fitted into the engaging hole 25 of the valve body 20 because the ice volume is larger than the volume of water. As a result, the movable member 40 is raised upward, the opening / closing protrusion 42 of the movable member 40 which is blocking the hollow portion 21 of the valve body 20 is raised upward, thereby opening and closing the movable member 40. A gap is generated between the protrusion 42 and the hollow portion 21 of the valve body 20.

이것에 의해, 텐션조절부재(70)의 중공부(71), 마개(50)의 중공부(52) 그리고 가동부재(40)의 절취홈(45)을 통과한 물이 가동부재(40)의 개폐돌기(42)와 밸브 바디(20)의 중공부(21) 사이에 틈새를 통해 밸브 바디(20)의 중공부(21)로 배출됨으로써, 수도관(110)의 물이 흐르게 되어 동절기에 수도관(110)이 동파되는 것을 방지할 수 있게 된다.
As a result, the water passing through the hollow portion 71 of the tension control member 70, the hollow portion 52 of the stopper 50, and the cutout groove 45 of the movable member 40 is transferred to the movable member 40. By discharging to the hollow portion 21 of the valve body 20 through a gap between the opening and closing protrusion 42 and the hollow portion 21 of the valve body 20, the water of the water pipe 110 flows to the water pipe (in winter) 110 can be prevented from freezing.
