Abstract: An anti-freezing apparatus comprises: a main block including an accommodation space and a water inlet at one side thereof to communicate with the accommodation space; a temperature sensitive member provided in the accommodation space and having one end for opening and closing the water inlet, the length of the temperature sensitive member variable due to expansion or contraction according to changes in temperature; an elastic member installed between the temperature sensitive member and the main block; a connecting rod connected to the other end of the temperature sensitive member; a locking part having opposite ends locked in a locking protrusion formed in the accommodation space and having a through-hole through which water passes; and an adjustment part coupled to the tip end of the connecting rod and rotatably screw-coupled to the locking part. The elastic member applies an elastic force to the temperature sensitive member to close the water inlet.

Abstract: A discharge device includes a dielectric, a first electrode and a second electrode arranged with the dielectric interposed therebetween, and a circuit unit to which the first electrode and the second electrode are electrically connected for generating a high voltage to be applied to the first electrode and to the second electrode. The dielectric is formed in a tube shape or a pipe shape having therein the circuit unit.

Abstract: The temperature-responsive fluid flow control apparatus of the present invention comprises: a housing installed between the inlet and the outlet of a fluid pipe in which a fluid flows; a valve block installed inside the housing to allow inflow of the flowing fluid in the housing and to discharge a portion of the flowing fluid to the outside according to the change in the internal pressure; and a temperature-responsive device for generating a pressure difference in the valve block according to the temperature change of the temperature-responsive fluid filled therein. The temperature-responsive fluid flow control apparatus prevents the fluid flowing pipe from freezing by discharging a portion of the fluid flowing in the housing to the outside, when the temperature of the temperature-responsive fluid reaches a preset temperature as the external temperature drops.
