| 摘 要： | 本文针对水下机器人在作业工具自动换接过程中的油路快速换接问题，提出了一种压差式快速自封接头，利用它可以在水中实现两液路的快速对接。这种接头具有自封闭功能，在两油路分离后可以防止外部的海水进入管路，也可以防止管路内的液体流出，连接后，在流体压差的作用下，两液路接通。本文介绍了该接头的结构和工作原理，并建立了对接头的开启压差及压力损失的数学模型。

| Abstract: | A kind of self-closed joint used for two oil citcuit connections of underwater robot is introduced in the paper. The joint is composed of two members which are mounted in the tool and the wrist. After they are disconnected, the joint with the self-closed function can prevent the outward seawater entering, and prevent the inner hydraulic oil drainning. After they are connected, the fluid circuit is opened by the pressure of the fluid. In the paper, the structure and the principle of the joint are presented, and the mathematical model of the pressure loss is founded. |
