Water valve for freeze protection
In the present invention, disclosed is a water valve for freeze protection, in which a stem holder for selectively opening and closing a waterway in the water valve is configured to be automatically operated according to the water pressure, so that, when the water pressure is lowered before the water in the water valve freezes in winter, the stem holder is operated to partially open the waterway and water is discharged little by little, thereby preventing the water valve from freezing and bursting.
본 발명은 수도밸브 내에서 수로를 선택적으로 개폐하는 스템홀더가 수압에 따라 자동으로 작동되는 구조를 갖도록 하여 겨울철에 수도밸브 내의 물이 동결되기 전에 수압이 낮아지면 스템홀더가 작동하여 수로가 일부 개방되면서 물이 조금씩 배출됨으로 수도밸브가 동파되는 것을 방지하는 동파방지용 수도밸브를 개시한다.
