FIELD: machine building.
SUBSTANCE: thermal shutoff valve contains housing with inlet and outlet pipes, shutoff member, seat and stock. Shutoff member is designed as spherical segment made from alloy with shape memory effect. Valve housing from the side opposite to inlet pipe is provided with screw mechanism. It consists of spool and stock with flywheel. Stock is in threaded connection with hex-shaped spool with spherical head. Spool is installed with possibility of translational displacement and deformation of spherical segment upon flywheel rotation.
EFFECT: simplifying the design providing reliable actuation for prompt shutoff of valve under preset temperature and return to initial state with dimensions of shutoff member being unlimited.
