The invention belongs to the technical field of safety valves, and particularly relates to a screwed anti-blocking pressure-limiting safety valve. Comprising a valve seat, an exhaust hole is formed in the valve seat, a connecting thread is arranged on the lower portion of the valve seat, and a multi-head external thread part is arranged on the upper portion of the valve seat; the valve body is arranged on the valve seat, a multi-section hole is formed in the valve body, and a multi-head internal thread part is arranged on the lower side of the multi-section hole; wherein the valve body and the valve seat are connected through matching of the multi-head external thread part and the multi-head internal thread part. According to the safety valve, the valve element for blocking the exhaust hole and the pressure stabilizing spring abutting against the valve ball are arranged in the multi-section hole, good safety pressure limiting and pressure stabilizing functions are achieved through cooperation of the valve bal
