Zusammenfassung:	The utility model belongs to the technical field of pipeline valves, and particularly relates to a safety valve which comprises a mounting plate, two connecting blocks are fixedly mounted at the top of the mounting plate, an air inlet pipe is fixedly mounted at the top ends of the two connecting blocks, and connecting holes are formed between the two connecting blocks and the air inlet pipe. A mounting plate is fixedly mounted at the top of the air inlet pipe, a mounting cavity is formed in the mounting plate, two through holes communicating with the mounting cavity are formed between the mounting plate and the air inlet pipe, vertical rods are movably mounted in the two through holes, valve blocks matched with the connecting holes are fixedly mounted at the bottom ends of the two vertical rods, and balls are rotationally mounted at the top ends of the two vertical rods; a sliding groove is formed in the inner wall of the top of the mounting cavity in the horizontal direction, and the same worm is rotationall
