    • A safety valve for battery has a valve body (1) and a valve core (2). The valve body (1) is fixed on a cover plate (4) of a battery and covers a discharging hole (9) in the cover plate (4) of the battery. The valve body (1) is formed with an exhaust opening (3) which is communicated with an internal space of the valve body (1). The valve core (2) is elastically held between a top cover (11) of the valve body (1) and the cover plate (4) of the battery. A plurality of columns (6) are arranged at intervals along a circumference of a gap between a side wall of the valve core (2) and an inner wall of the valve body (1). A cavity defined by every two adjacent columns (6), the side wall of the valve core (2) and the inner wall of the valve body (1) forms as a side exhaust slot (7) which is communicated with the exhaust opening (3) in the valve body (1).
    • 电池用安全阀具有阀体(1)和阀芯(2)。 阀体(1)固定在电池的盖板(4)上并且覆盖电池的盖板(4)中的排出孔(9)。 阀体(1)形成有与阀体(1)的内部空间连通的排气口(3)。 阀芯(2)弹性地保持在阀体(1)的顶盖(11)和电池的盖板(4)之间。 多个柱(6)沿着阀芯(2)的侧壁和阀体(1)的内壁之间的间隙的圆周间隔设置。 由两个相邻的柱(6),阀芯(2)的侧壁和阀体(1)的内壁限定的空腔形成为与排气口(7)连通的侧排气狭槽(7) 3)在阀体(1)中。
