A self-locking inflation valve works by having an extension inflation tube adapted to an aerator to execute locking in fashion of rotation and insertion to enable the inflation valve of the object to be inflated self-locking and secured type of opening for the object to achieve dual efficacies of inflation or air suction/drain; a mortise being provided in relation to the extension inflation tube on the inner edge of the end of an inflation valve assembly to enable self-locking when the tube being coupled into the mortise to force the inner valve to retreat thus to open up the inflation valve gate; and the inflation valve gate being automatically shut off through a built-in coil once the extension tube clears away from the mortise.
