PURPOSE: A heat reactive valve is provided to mechanically operate according to external temperature without a power source by preparing mechanism which is operated by heat energy due to external heat. CONSTITUTION: A heat reactive valve comprises a hollow case(10), a drive material(20), a rod(R), a movement prevention member, a slider(40), and an opening and shutting machine(50). The drive material provides drive force using heat energy transferred from the outside. The rod is formed inside the case and is pressed by the drive force of the drive material. The movement prevention member prevents the rod from being moved by the drive material. The slide glides along the rod by the reaction force generated by preventing the movement of the rod. The opening and shutting machine opens and shuts a valve seat(VS), moved by the slider. |
