    • A diaphragm seal (101) for a cable gland (Figure 1) has concentric inner (103) and outer (105) cylindrical seal walls connected at one end by a diaphragm (107) to define a cavity (121). The cavity (121) contains a plurality of support webs (125) that extend between the inner (103) and outer (105) seal walls. The webs (125) are provided on an exit side of the seal (101) and deform to assist insertion of the cable through the seal (101) from an entry side of the seal (101). The webs (12) resist inversion of the seal (101) when the pressure on the exit side is higher than the pressure on the entry side to create a pressure differential across the diaphragm (107).
    • 用于电缆密封套(图1)的隔膜密封件(101)具有同心的内部(103)和外部(105)的圆柱形密封壁,其一端通过隔膜(107)连接以限定空腔(121)。 空腔(121)包含在内(103)和外(105)密封壁之间延伸的多个支撑腹板(125)。 腹板(125)设置在密封件(101)的出口侧并且变形以帮助电缆从密封件(101)的入口侧穿过密封件(101)插入。 当出口侧的压力高于入口侧的压力以在横跨隔膜(107)上产生压力差时,腹板(12)抵抗密封件(101)的反转。
