Optimal Design and Test of Hydraulic Couplings in Docking Plate of Subsea Control System

ZHANG Pengju;MSP/DRILEX (Shanghai) Co.,Ltd.;  
The article introduces a kind of hydraulic couplings by optimizing design. The coupling uses 4-lines of seat gate which can be sealed ensemble. It can connect 4 hydraulic ways at the same time. Meanwhile the design also has the advantages of high performance of sealing, high reliability and actuating efficiency. By theoretical analysis of mechanical stress strength and sliding resistance for 4-lines coupling, and by performance tests, the product is firmly tested to fulfill the reliability under different circumstances.
