An exhaust pipe system for conducting exhaust gas from a combustion device to an exhaust system includes a first exhaust pipe with an inlet end and an outlet end, and a second exhaust pipe having a first line end and a second line end, wherein the inlet end of the first exhaust pipe is connectable to the first line end of the second exhaust pipe via a detachable coupling connection. A locking member is arranged to be movable between a closed position closing a passage and an open position opening the passage inside the first exhaust pipe. When the coupling connection is released, the locking member is automatically arranged in the closed position, and the second exhaust pipe has an actuating member which, when the coupling connection is established, urges the locking member into the open position.

A connector for the reciprocal connection of an end member of a water supply or of a sprayer with a flexible hose includes a tubular main body defining an axis and having a first end portion for coupling with the end member and a second end portion that includes an elongated spigot, on which an end of the flexible hose may be fitted, and further includes an abutment wall, from which the elongated spigot extends. The connector also includes a substantially tubular shaped ring nut placed peripherally to the spigot and reciprocally screwable with the main body, and an annular pressure element interposed coaxially between the ring nut and the spigot.

Example implementations relate to a magnetic fluid connector. For example, a magnetic fluid connector can include a magnet, an internal fluid path defined by a first portion and a second portion when the first portion and the second portion are coupled together, and a movable member that is movable to seal the internal fluid path, where the magnet provides at least a portion of a force sufficient to seal the internal fluid path.

An adapter for connecting components in a fluid system has an adapter body defining a cylindrical space and lock buttons which are biased into a locked position to secure the adapter to another component. The adapter body has a circular collar defining an inlet into the cylindrical space, a channel defining an outlet out of the cylindrical space, a support wall and a support flange defining one or more cutouts in an outer cylindrical side wall of the adapter body, and a slot defined between the collar and the support wall connecting the one or more cutouts to the cylindrical space. The lock buttons have a contact element positioned in one of the cutouts and an arm projecting positioned in the slot. The arms are partially in the cylindrical space in the locked position and are movable into an unlocked position when the contact elements are moved toward each other.

A system includes a flow control assembly having a first portion configured to be positioned within and coupled to a first passageway formed in a wellhead component and a second portion configured to be coupled to a second passageway formed in a body that is configured to be coupled to the wellhead component. An actuator of the second portion is configured to drive a valve member of the first portion into an open position to enable fluid flow across the flow control assembly.

A deflation apparatus includes a cylindrical deflation main body including a socket portion and an exhausting portion. The socket portion includes an opening for receiving a spool of a valve and the opening is connected to an inner space, being through the socket portion and the exhausting portion, and an outer wall of the exhausting portion includes a plurality of exhausting holes connected the inner space. An exhausting direction of the exhausting holes is vertical to the longitudinal axis of the deflation main body. A flat stream leading portion, in the inner space, is configured to separate the inner space to form at least two exhausting channels. Each of the exhausting channels is connected to at least one of the air exhausting holes. An abut side of the flat stream leading portion, extended toward the opening, is abutted the spool of the valve.
