An anti-freezing system for a pipeline is provided to use the valve in a long time by returning a valve to the original state after discharging the fluid of a pipeline if temperature falls down less than the freezing temperature. An anti-freezing system(100) for a pipeline is composed of a valve connector(111) which is combined with an outlet(211) formed in a pipeline port(210) of a movable pipeline(200), an opening-and-closing pressure controller connector(112) which is formed to the opposite side of the valve connector, an opening-and-closing piston fixture connector(113) which is formed vertically about the valve connector and the opening-and-closing pressure controller connector, a valve body having piston supporter(114) formed within the valve connector side, an opening-and-closing piston(120) having a packing member(121) for preventing water leakage of the movable pipeline, a pressure control elastic member(130) whose one side is combined to a position fixture(122) of the piston and the other side is supported by the opening-and-closing pressure controller, an opening-and-closing pressure controller(140) which is combined to the opening-and-closing pressure controller connector and supports the one side of the pressure control elastic member, and a fixture fixing and moving the opening-and-closing piston. |
