Anti-burst safety valve for chemical engineering

The utility model discloses an anti-burst safety valve for chemical engineering. The anti-burst safety valve comprises an upper valve shell, a lower valve shell, a flow inlet, a first flange, a flow outlet, a second flange, a disc, a connecting rod, a guide sleeve, a straight rod, a piston plate, a rubber sleeve, a first spring, a transverse rod, an overflow port, a cover plate, a second spring, atransverse reinforcing rib, a vertical reinforcing rib and a rubber cushion. The safety valve is reasonable in structure, compared with a traditional safety valve, the outer wall of the safety valveis provided with the transverse reinforcing ribs and the vertical reinforcing ribs, the reinforcing effect is achieved, the overall strength is improved, a reinforcing supporting mechanism is furtherarranged in the safety valve and used for reinforcing the interior, and therefore the overall anti-burst capacity is greatly improved; compared with a traditional safety valve, the automatic sealing mechanism is additionally ar
