The Design of a Mechanical Temperature-driven Shut-off Valve

Abstract The structural design of a mechanical temperature-driven shut-off valve used in the water and steam sampling device power plant is designed using Iventor drawing software. A NiTi shape memory alloy with high temperature-sensitivity as driven spring to control opening closing valve. In addition structures common parts valve, calculation parameter-design are also carried out. unimpeded can take water-steam samples under normal state. When temperature exceeds 49 oC, will be shut off due extends intake stop. it necessary again, reset manually.
