Design of Quick Connect-Disconnect Hydraulic Coupling
International Journal of Recent Advances in Mechanical Engineering (IJMECH) ISSN: 2200-5854 http://wireilla.com/engg/ijmech/index.html ABSTRACT Quick Connect-Disconnect Couplings (QCDCs) provide a means of rapidly disconnecting a fluid line without loss of hydraulic fluid or entrance of air into the system. They are most commonly used for hydraulic systems in aerospace applications like space stations, launch vehicles, etc. Information regarding the design of QCDCs is not available in open literature. This paper details the preliminary design and optimization of QCDCs for indigenization of the technology, and the general configuration arrived at. AQCDC consists of two halves – a male half and a female half. The sealing action is achieved by using poppet valve in the male half and a moveable sleeve in the female half. O-rings are used to ensure that the design is leak-proof. Changes in pressure and velocity of the fluid flowing through the QCDC have been kept to a mini...
