The invention discloses a pressure compensation device which comprises a connecting cavity and air bag shells installed at the left end and the right end of the connecting cavity, an inflation pressure regulating valve is arranged on the connecting cavity, sealing air bags are arranged in the air bag shells, and one ends of the air bag shells are sealed with the connecting cavity through sealing faces on the edges of the sealing air bags. A pore plate is mounted at an opening in one end, and the maximum volume of the single-side sealing air bag in a static state is larger than the sum of the volume of the connecting cavity and the volume of the air bag shell; the pressure compensation device is used for pressure compensation of deep sea electromechanical equipment, and compared with a traditional pressure compensation device, the pressure compensation device has the advantages of being adjustable in compensation size, simple in structure, high in reliability, wide in application range and the like.

    本发明公开了一种压力补偿装置,包括连接腔体以及安装在连接腔体左右两端的气囊外壳,连接腔体上设置有充气调压阀,气囊外壳内均设置有密封气囊,气囊外壳一端通过密封气囊边缘的密封面实现与连接腔体之间的密封,一端的开口处安装有孔板,静止状态下单侧密封气囊的最大容积大于连接腔体容积与气囊外壳的容积之和;本发明用于深海机电设备的压力补偿,与传统的压力补偿装置相比,除了具有补偿体积可调的特点,还具有结构简单、可靠性高、适用范围广等特点。
