A docking fixture for removal of a valve core from a valve fitting of a pressurized system includes a main body defining a hollow main channel that receives a gripping probe to remove the core of a charging valve that is part of a pressurized HVAC system. The docking fixture has a proximal end that can be connected to the HVAC fitting that houses the valve core that is to be removed and replaced. The docking fixture has a side port integrated with a slide valve that can be closed to isolate and protect a sensitive vacuum pressure gauge that might be connected to the free end the fixture's side port. The slide valve includes a sleeve and a tactile feedback mechanism that is configured to provide tactile sensation when the sleeve is positioned in one of the open position and the closed position of the slide valve.

A sprinkler configured for engagement with a coupling, the sprinkler includes a raised lip end, the sprinkler defining a raised lip at the raised lip end; and a deflector end disposed opposite from the raised lip end, the sprinkler defining a groove between the raised lip and the deflector end.

A pressure relief ball valve to prevent excessive pressure buildup due to freezing liquid includes a ball that is rotatably housed within a valve body. A fluid conduit traverses through the ball, wherein rotation of the ball via a lever handle either aligns or disjoints the fluid conduit with an inlet and an outlet of the valve body. Meanwhile, a drain hole traverses into the ball and intersects the fluid conduit. When the ball is toggled to an open position, the drain hole is positioned adjacent to a side wall of the valve body, such that the drain hole is capped off. When the ball is toggled to a closed position, the drain hole is positioned adjacent to the outlet, wherein residual liquid is expelled from the fluid conduit. The removal of residual liquid prevents excessive pressure buildup due to freezing liquid within the valve body.

A multi-fitting rotatable fluid connection apparatus comprising a fluid entry fitting and first and second fluid discharge fittings. The fluid entry fitting comprises a first end connector threaded for attachment to a fluid source, and first and second distribution connectors. The first fluid discharge fitting has a first intake connector which receives fluid from the first distribution connector. A first rotation member is coupled between the first intake connector and the first distribution connector such that the first fluid discharge fitting is rotatable about a first axis of rotation. The second fluid discharge fitting has a second intake connector which receives fluid from the second distribution connector. A second rotation member is coupled between the second intake connector and the second distribution connector such that the second fluid discharge fitting is rotatable about a second axis of rotation.

A pipe fitting having a base configured to engage with a pipe, the base having a mounting seat configured to engage directly with the pipe, a base ring configured to engage with the mounting seat, and a base flange configured to engage with the base ring, a top hat configured to engage with the base, the top hat having a top cap, a top hat ring configured to engage with the top cap, and a top hat flange configured to engage with the top hat ring, wherein the top hat flange is further configured to engage with the base flange to form a fitting cavity. A pipe flow controller may be in fluid communication with the internal pipe volume through a threaded nipple, while also being securely housed within the fitting cavity, thus protecting the pipe flow controller from corrosion, impacts and other forms of damage to prevent leakage.

An intermediate bulk container, valve and connector system is provided that includes a split nut connector. The split nut connector is rotatably mounted on a valve adapter plate which connects with the valve, and is internally threaded for engagement with external threads on the intermediate bulk container outlet. An O-ring seal is aligned and positioned between the adaptor plate inlet and intermediate bulk container outlet by positioning surfaces to provide compression and sealing between the component engaging surfaces, and sealing contact is provided between corresponding surfaces of the components.

A trunnion ball valve provides a reliable seal when closed, while minimizing or eliminating frictional resistance during rotation of the ball. A pressurization chamber behind the upstream valve seat can be interconnected by one or more pressurization valves with either the upstream or the downstream process fluid. The interconnection can be via a single 3-way valve. When the valve is closed and the ball is fixed in orientation, the pressurization chamber is automatically connected to the upstream process fluid, thereby pressing the seat against the ball and ensuring a reliable seal. While the ball is being rotated, the pressurization chamber is automatically connected to the downstream process fluid, thereby substantially eliminating valve seat friction. Connection to the downstream process fluid can include connection to a small space in front of the upstream seat. An electronic controller can control both valve stem rotation and the pressurization valves.

An apparatus for handling fluid within an at least partially electrically driven vehicle, with a valve device including a valve housing. The valve housing includes at least three two radially arranged port openings and at least one axially arranged port opening for the inflow and/or outflow of fluid, and a valve body which is arranged inside the valve housing and is configured to be rotatable about an axial axis of rotation R. The valve body includes a first connecting channel of arcuate shape for connecting two radially arranged port openings and a second connecting channel of arcuate shape for connecting a radially arranged port opening with an axially arranged port opening. The at least two radially arranged port openings define a base plane B, which is configured orthogonally to the axial axis of rotation R, and the first arcuate connecting channel defines a first connecting channel plane V.

A multi-fuel switching device, including a gas part, is provided. The gas part includes a switching valve. The switching valve includes a housing having an air inlet and an air outlet. An internal rotation of the housing is provided with a valve core located between the air inlet and the air outlet. The valve core is provided with a first airway and a second airway. Cross-sectional sizes of the first airway and the second airway are different. The first airway or the second airway is selected through rotating the valve core to connect the air inlet and the air outlet. The solution solves the issue that a fuel switching device in the prior art cannot adapt to three or more fuels, which causes an internal combustion engine to be unable to maintain the optimal working state.

Illustrative embodiments of a meter box and couplings, either separately or in combination, are provided. An illustrative embodiment provides a valve coupling that is disposed through a wall of the meter box such that a first portion of the valve coupling extends exterior of the meter box and a second portion of the valve coupling extends interior of the meter box. An outlet coupling is disposed through the wall of the meter box such that a first portion of the outlet coupling extends exterior of the meter box and a second portion of the outlet coupling extends interior of the meter box. A telescoping tube is located in the meter box, extended into and movable relative to, and in fluid communication with, at least one of the second portion of the valve coupling and/or the second portion of the outlet coupling. The telescoping tube varies a distance between the valve coupling and the outlet coupling within the meter box.
