A circuit breaker for connecting two line segments of a facility for handling pressurized fluid, the circuit breaker comprising:
- a male element and a female element that are intended to fit in one another along a fitting axis, the male element including a male body defining a first inner pipe for circulating pressurized fluid and provided with
- at least one member for closing off a front end of the first inner pipe along the fitting axis,
- at least one first passage, radial with respect to the fitting axis and connecting the first inner pipe to the outside of the male body in an uncoupled configuration of the male element and the female element of the circuit breaker, and
- a locking notch arranged on the male body
- the male element provided with a valve, the valve of the male element movable in the first inner pipe relative to the male body,
- the female element including a female body defining a second inner pipe for the circulation of pressurized fluid and provided with
- at least one second passage, radial with respect to the fitting axis and connecting the second pipe to a volume receiving the male body in the female body, and
- several locking members movable transversely with respect to the fitting axis, in housings of the female body, between a first radial position, where the locking members are engaged in the locking notch, for the axial locking of the male body with the female body in a coupled configuration of the male element and the female element of the circuit breaker, and a second radial position, where the locking members free the passage of the male body in the female body,
- the female element provided with a valve, the valve of the female element movable in the second inner pipe relative to the female body,
- wherein, in the coupled configuration, the first and second radial passages are in communication, while a first sealing gasket and a second sealing gasket are arranged, along the fitting axis, on either side of the first and second radial passages and respectively cooperate radially with the male body and the female body,
- wherein a resilient return ring is mounted on the female body and surrounds the locking members, the resilient return ring configured to resiliently return the locking members toward the first radial position in the coupled configuration and to be deformed radially, and resiliently, by the locking members during movement thereof, from the first radial position toward the second radial position, and
- wherein the circuit breaker includes a rod for maneuvering a first valve from among the valve of the male element and the valve of the female element, the rod passing through a first body, formed by the male body or the female body and housing the first valve, with interposition of a third sealing gasket between the first body and the rod, the rod slidably mounted in the first body along a direction parallel to the fitting axis, and wherein a second body, from among the male body and the female body, defines a bearing surface of the rod, the bearing surface being stationary with respect to the second body and configured to push the rod toward a rear of the first body, during fitting of the male element and the female element, to move the first valve from a closed position to an open position of an inner pipe of the first body.
