The urgent separable coupling null Drive with zero spill duplex ball valves

摘要

(57) Abstract In order it is the urgent separable fluid coupling assembly body in order the coupling to do two fluid conveying components to which each one has internalized the ball valve, as for the particular assembly body, for each one to have the open destal (12 and 14), as for the particular destal (12 and 14) to be able to join mutually closely, the component (16 and 18) is applied for 1st and 2nd fluid conveyance which, said being the 1st and 2nd rotary ball valve (20 and 22) which is respectively accepted to the open destal (12 and 14) of the component for 1st and 2nd fluid conveyance, each oneThe said ball valve (20 and 22) with open position and closed position in order to be able to turn, the 1st and 2nd rotary ball valve which is formed, said containment the component (16 and 18) for 1st and 2nd fluid conveyance mutually in engagement state, at the same time said the concatenated component (98, 100, 102 and 104) in order to prevent the fact that the component (16 and 18) for 1st and 2nd fluid conveyance choice, is separated from mutual engagement state, said the component for 1st and 2nd fluid conveyance (16,18), when said each one of the 1st and 2nd ball valve (20 and 22) is a closure position only, separable means (62 and 109) in order to try to be able to separate choice, with the urgent separable fluid coupling assembly body which features that it consists of.
