The invention provides an intelligent safety valve for an elevator. The intelligent safety valve for the elevator is used for being installed on bilateral walls of an elevator doorway. A safety valve cover plate is arranged on a safety valve baseplate. A lateral wall of the safety valve baseplate is provided with a safety valve upper and lower arms driving component. The safety valve upper and lower arms driving component drives a safety valve upper arm and a safety valve lower arm to rotate. One side of the safety valve upper arm and one side of the safety valve lower arm are both provided with a locking mechanism. The other lateral wall of the safety valve baseplate is provided with an emergency handrail driving component. The emergency handrail driving component drives an emergency handrail to rotate. The emergency handrail is installed on one side of the lateral wall of the safety valve baseplate; the other side is provided with a light curtain. A central information processor and a stabilized power source are arranged inside the safety valve baseplate. The intelligent safety valve for the elevator has the advantages of simple structure, scientific and reasonable design, simple and convenient installation, low cost, and strong safety valve strength; when the elevator abnormally ascends or descends in a failure, the movable body of the high-strength safety valve can press against the elevator carriage, thereby preventing people from being injured.
