    摘要: A safety discharge valve, the structure whereof comprises a siphon-type open/close device (1), a valve cover assembly (2), a valve rod (3), a valve body (4), an extensible side-sealing top-pressing assembly (5), side rotary sealing plates (6), a tapered bottom valve plug (7) and a side water inlet emergency plug (10). The siphon-type open/close device (1) is connected to an open/close nut (8) of the valve cover assembly (2). The top of the valve rod (3) is slidably connected with the center of the valve cover assembly (2) and is sealed inside a sealed valve rod cavity (62), below the bottom of the piston (24) and above a sealing filler (55). The lower part of the valve rod (3) is arranged inside of the valve body (4). The side of the valve body (4) is provided with side water inlets (14) and the bottom of the valve body (4) is provided with a tapered bottom water outlet (16). The lower end of the valve rod (3) is connected with a tapered bottom valve plug (7). The lower tapered part of the tapered bottom valve plug (7) is matched with the tapered bottom water outlet (16). The extensible side-sealing top-pressing assembly (5) is arranged between the tapered bottom valve plug (7) and a holding piece (11). The two top ends of each side of the extensible side-sealing top-pressing assembly (5) press upon the smooth back surface of the side rotary sealing plates (6) in rolling-sliding contact therewith. The side rotary sealing plates (6) are rotatably connected with suspension brackets (12). The front sealing surfaces of the side rotary sealing plates (6) fittingly connect with the sealing surface of the side water inlets (14). The smooth back surface is inclined at an angle of five degrees relative to the central axis of the valve rod (3). The side water inlet emergency plug (10) is extractably-connected with an extractable cap (9) on the valve cover assembly (2).
