The invention discloses a pressure stabilizing gas bulkhead sealing device which comprises a sealing piece body, the sealing piece body is fixedly connected to a bulkhead wall through a connecting sealing plate, the sealing piece body and the connecting sealing plate are both of split type annular structures, a plurality of sealing ring gear rings are arranged in an inner hole of the sealing piece body in the axial direction, an expansion cavity is formed between every two adjacent sealing ring gear rings, and the expansion cavity is communicated with the sealing piece body. An air inlet connector and an air exhaust connector are arranged on the side wall of the sealing element body, the air inlet connector is communicated with the expansion cavity at one end, a sealing sleeve fixedly connected with a transmission shaft is arranged at the position of the sealing ring gear ring adjacent to the other end of the sealing element body, the sealing ring gear ring is embedded and inserted in a sealing ring groove in the periphery of the sealing sleeve, and the air exhaust connector is communicated with the other expansion cavities; the sealing piece body, the connecting sealing plate and the bulkhead of the bulkhead are connected in a sealed mode through sealant. By the adoption of the pressure-stabilizing gas compartment sealing device, abrasion of the sealing device can be avoided, and cleanliness in the gas inlet pressure-stabilizing compartment can be guaranteed.

    本发明公开了一种稳压气体隔舱密封装置,包括密封件本体,密封件本体通过连接封板安装固连在隔舱壁上,密封件本体和连接封板均为剖分式环状结构,在密封件本体内孔中沿轴向设有数个密封环齿圈,相邻密封环齿圈之间设有膨胀腔,在密封件本体的侧壁上设有进气接口和抽气接口,进气接口与一端膨胀腔通连,在与密封件本体的另一端相邻的密封环齿圈处设有与传动轴固连的密封套,该密封环齿圈嵌插于密封套外周的密封环槽中,抽气接口与其余各膨胀腔通连;密封件本体、连接封板及其与隔舱舱壁之间均通过密封胶密封连接。采用本发明的稳压气体隔舱密封装置不仅能避免密封装置的磨损,还能保证进气稳压舱室内的洁净。
