A safety valve of a lubricator according to the present invention comprises: a discharge housing connected to a lubricator nozzle; an injection housing which is connected to a fuel hose from the lubricator and inserted in and coupled to the discharge housing, which has a fuel passage formed therein, and which blocks the fuel passage when the discharge housing is separated therefrom; and a main C ring provided between the injection housing and the discharge housing to separate the discharge housing from the injection housing when fixed tensile force or greater force is applied to the discharge housing. The safety valve of the lubricator is provided with the main C ring between the injection housing and the discharge housing to separate the discharge housing from the injection housing when fixed tensile force or greater force is applied to the discharge housing, and with an assembly groove of a discharge housing and a structure of the main C ring so that the separation load of the discharge housing for the injection housing is 100-350 pounds. The safety valve of the lubricator is provided to properly function as a safety valve and to prevent damage to the main C ring and the assembly groove even though the discharge housing is separated from the injection housing, thereby being recycled and reducing maintenance costs. |
