Title: 수도관 동파방지기
Inventor: LEE JONG HUN
Filed: 2001-10-05
Abstract: 본 발명은 수도관로 결빙에 따른 수도관의 동파를 방지할 수 있도록 할 목적을 갖는 것으로서, 심봉(9)상에 제1스프링(8), 심봉(9)하에 제2스프링(10)(일반스프링), 개폐공(6)이 순차적으로 삽입하여 개폐공이 심봉과 일체로 결합되어 고정되고, 제1스프링 및 제2스프링의 압력차이에 의해 심봉 및 그와 결합된 개폐공이 유동이 이루어지도록 구성되며 수도관로와 결합되는 구조의 본체(b)로 이루어지고, 제1스프링 또는 제2스프링 중 제1스프링은 2℃이하에서 탄발력의 변화를 갖는 형상기억합금소재의 스프링으로 구성함으로서 2℃ 이하의 온도에서 개폐공이 밀어 배수구가 열릴 수 있게 결합하는 구성을 특징으로 하는 수도관 동파 방지기를 제시한다. 
     도면2 개폐공(4)이 원수를 막으면 , 통수구(7)(7-1)를 통하여 물은 본체(b)로 간다. 도면3과 같이 표준온도일 때 제1스프링이 강화되므로 제2스프링과 심봉(9) 및 개폐공이 배수구를 막아주고 도면4와 같이 온도가 2℃ 정도가 되면 그림과 같이 제1스프링은 압축되므로 제2스프링과 심봉(9) 및 개폐공(4)이 위로 상승하게 되므로 모래층 배수구를 통하여 수도관의 물이 빠짐으로 동파가 방지된다.
