A valve for preventing water hammer includes a speed reduction device for reducing a speed at which the valve may be closed. A method of preventing water hammer includes closing a valve at a fire hydrant after extracting water from the fire hydrant, in which the valve comprising a speed reduction device that increases an amount of time needed for closing the valve, and operating the valve to close the valve comprises operating the speed reduction device.

A tank container for bulk storage of liquid materials is provided with with remote operated valves. The tank container comprises a storage vessel for bulk storage of liquid materials and having a height of about eight feet. The storage vessel includes an outlet valve proximate a bottom of the vessel, a fill valve at a top of the vessel, and a vent valve at the top of the vessel. A parallelepiped frame surrounds and is secured to the storage vessel for stacking and transporting of the tank container. A fill line includes an outlet connected to the fill valve and extending downwardly within the frame and an inlet proximate the bottom of the frame. A fill valve actuator is mounted proximate the bottom of the storage vessel mechanically linked with the fill valve for operating the fill valve remote from the top of the storage vessel. A vent valve actuator is mounted proximate the bottom of the storage vessel mechanically linked with the vent valve for operating the vent valve remote from the top of the storage vessel.

A handle assembly for an outlet valve for a tank, where the outlet valve has a stem that is actuated to open and close the outlet valve, is provided. The handle assembly includes a handle. A shaft is attached to the handle, and an adapter attached to the shaft. A bracket is adapted to mount the shaft to the tank so that the shaft is pivotally mounted with respect to the tank and movable with respect to the outlet valve between an engaged position, where the adapter is connected to the stem, and a disengaged position, where the adapter is disconnected from the stem.

A valve for use in a tank vessel that includes a valve housing configured to fit into a threaded vent opening of the tank vessel and a sleeve weldment coupled to the valve housing. The sleeve weldment includes a first end configured to protrude into an interior volume of the tank vessel, and the first end is thermally balanced with the interior volume of the tank vessel. The valve also includes a valve plunger configured to be installed within the sleeve weldment. The valve plunger includes a valve bottom configured to seal an opening between the valve bottom and an interior opening of the sleeve weldment. The valve also may include a cam configured to force the valve plunger into the interior of the tank vessel to break the seal between the valve bottom and the interior opening of the sleeve weldment.

A valve assembly for controlling the release or delivery of a fire suppression medium from a vessel, the assembly comprising an inlet connectable to a pressurised vessel, an outlet connectable to a delivery device, a valve operable to selectively open or close fluid communication between the inlet and the outlet, an opening device for moving the valve from a closed condition to an open condition, first and second actuators and an environmental triggering device, wherein the opening device is operable, in use, remotely by the first actuator or manually by the second actuator or automatically by the environmental triggering device. A fire suppression system employing the above-described valve and a vehicle including the fire suppression system also form a part of this invention.

A number of variations may include a product comprising: a linkage system comprising: a first and second lever; a first interconnecting component and second interconnecting component operably connected to the first and second levers; a link bar having a first end with a first opening for receiving the first or second interconnecting component, and providing a clearance between the first opening and the first or second interconnecting component and; a second end with a second opening for receiving the first or second interconnecting component and providing a clearance between the second opening and the first or second interconnecting component; and a biasing device having a first and second end for engagement with the first and second interconnecting components and at least one section to allow for increasing or decreasing its length, wherein when the first or second end of the biasing device is engaged with one of the first or second interconnecting component and an external force is applied to one of the first or second ends of the biasing device to cause the biasing device to either increase or decrease in length to allow engagement with one of the first or second interconnecting component and to store energy, and wherein when the external force is removed from the biasing device, the stored energy of the biasing device provide a force that causes the first and second interconnecting components to move in a direction that overcomes the clearances between the first and second interconnecting components and the first and second openings of the link bar and provides contact between the first and second interconnecting components and the first and second openings of the link bar and wherein the contact is maintained by the force provided by the stored energy.

A wedge-shaped gate valve with a branching part formed to be open in a direction orthogonal to an inner flow path of a valve box having a coupling part on both sides, and a valve disk ascends and descends from the branching part via a valve stem to open and close an annular valve seat surface. At a boundary between the coupling part and the branching part, a reinforcing thickened part having a cylindrical, cone, or truncated cone shape with a diameter gradually reducing from the branching part toward the coupling part side is provided, and the thickened part is formed by taking, as an outer shape, a cylinder, a cone, or a truncated cone with an axis P2 that is eccentric from a center line P1 of the flow path to the branching part side and is parallel to or crossing the center line P1 as a rotation axis.

A plumbing fixture fluid diversion assembly minimizes dripping from an outlet conduit of a spout body by restricting passage of accumulated fluid through the outlet conduit. The assembly comprises a hollow spout body having an inlet conduit that carries fluid to a diversion chamber. The diversion chamber is in communication with the inlet conduit and the outlet conduit. A routing notch helps control the flow of the fluid towards a chamber opening that is disposed between the diversion chamber and the outlet conduit. The chamber opening enables passage of fluid to the outlet conduit. A flap selectively covers and uncovers the chamber opening to control dripping from the outlet conduit. The assembly generates an initial force to at least partially urge the flap towards the chamber opening for covering by pulling a cable, displacing magnet proximal to the flap, or creating a vacuum to displace the flap.
