A valve assembly includes a body, a spring, a spacer, an interfacing member, a connecting rod, and a plunger. The body includes a first section defining a first opening, a second section defining a chamber, a second opening, and a pressure port, and a third section defining a third opening and a release port. The second section is between the first section and the third section. The spring is positioned within the third opening. The spacer is positioned within the third opening and coupled with the spring. The interfacing member is positioned partially within the third opening and coupled with the spacer. The connecting rod is positioned partially within the second opening and the chamber and coupled with the interfacing member. The plunger is positioned within the chamber and coupled with the connecting rod.

Automatic fluid control assemblies and methods for fire protection include an arrangement of electrically operated control points, a valve body and a controller to operate the fluid control assembly. The automatic fluid control assembly has an inlet, an outlet and a valve body to control flow between the inlet and the outlet. An electric latch includes a first electrically operated control point and a second electrically operated control point in fluid communication with a control line to control the flow of fluid from the inlet to the valve body and outlet. The methods of fluid control include controlling a plurality of electrically operated control points to perform any one of: a leak test, a trip test, a flow test, a water delivery test, and a validation test of a non-trip condition and a trip condition.

Fluid control assemblies for sprinkler systems

Systems, apparatuses, and methods of assembly of a dry pipe manifold assembly. The dry pipe manifold assembly including a lower plate and an upper plate fixed to the lower plate creating a water passage with a series of ports. The assembly further including a dry pipe actuator, manual reset actuator sub-assembly, manual trip valve, and alarm test sub-assembly fixed to the upper plate. The assembly allowing for fluid flow between the dry pipe actuator, manual reset actuator sub-assembly, and manual trip valve through the water passage.

A manual reset actuator includes a main drain, a diaphragm release aperture fluidly coupled to a flow control valve, an upper chamber, a control port, a control orifice, an upper chamber supply orifice, and a sealing assembly, which includes a button, and a plunger. A pressure in the upper chamber exerts a downward force on the plunger. A spring exerts an upward force on the plunger. The fluid in the upper chamber is released via the control orifice, which lowers the pressure in the upper chamber, decreasing the downward force exerted on the plunger. When the downward force is less than the upward force, the spring forces the plunger upwards into an open configuration, which unseals the diaphragm release aperture. When the upward force is less than the downward force, the plunger remains in a closed configuration, which keeps the diaphragm release aperture sealed.

A sprinkler accelerator system includes an accelerator and at least one orifice. The accelerator is coupled with at least one pipe coupled with at least one sprinkler, and vents gas from the at least one pipe when the at least one sprinkler opens. The at least one orifice controls a rate of change of pressure in the at least one pipe to control operation of a flow control valve coupled with the accelerator.

A fluid control valve includes a cover portion and a body portion. Inner surfaces of the cover and the body portion define a chamber that includes an inlet and an outlet in communication with the chamber. The cover portion includes a central section and an inversion inhibitor circumscribing the central section. The inversion inhibitor projects into the chamber toward a central axis of the chamber. The fluid control valve also includes a diaphragm disposed between the cover portion and the body portion. The diaphragm has a flexible member that is disposed within the chamber for controlling communication between the inlet and the outlet. The inversion inhibitor prevents the flexible member from reaching its natural-inverted position and creates a force within the flexible member that urges the flexible member to a seated position. In the partially inverted position, the upper surface of the flexible member conforms to at least a portion of the inner surface of the cover portion to define a passageway that permits communication between the inlet and the outlet.

A system and method for notifying drivers of an emergency condition along a highway includes mounting a plurality of speed control assemblies in a ground surface beneath the highway, each identifier including a geographic component. This method includes selectively moving a speedbump portion between retracted and raised configurations a predetermined distance above the highway. Alert data including an alert location may be communicated from a traffic control agency to the traffic control assemblies. Using the plurality of identifiers, this method includes identifying respective speed control assemblies that are located within a predetermined distance upstream of the alert location and incrementally actuating the identified speed control assemblies to the raised configurations, respectively. Each incrementally raised configuration causes an increased impact with an associated sound and vibrational sensation to an automobile traveling upon the highway upstream of the alert location.

Examples of a leak detection system are disclosed. In one example according to aspects of the present disclosure, a leak detection system includes a housing defining an interior, the housing connected to a component of a water distribution system. The leak detection system also includes a leak detection sensor contained within the interior of the housing and configured to detect a leak within the water distribution system. Additionally, the leak detection system includes a digital signal processing circuit in communication with the leak detection sensor.

A nozzle cap assembly includes a nozzle cap defining a bore, the bore defining internal threading configured to mount the nozzle cap on a nozzle of a fire hydrant; an enclosure attached to the nozzle cap; a vibration sensor positioned within the enclosure; a circuit board positioned within the enclosure, the circuit board connected in electrical communication with the vibration sensor, the circuit board configured to process an electrical current transmitted by the vibration sensor; and an antenna connected in electrical communication with the circuit board, the antenna configured to transmit a signal received from the circuit board.

Systems and methods of an integrated fluid control valve and valve actuator assembly are provided. The assembly includes a pressure operated fluid control valve for controlling the flow of liquid from a liquid supply piping system into a sprinkler piping system of a fire protection system when transitioning the fire protection system from a stand-by state to an actuated state. The control valve defines a valve chamber for holding a pressurized fluid to prevent the flow of fluid through the control valve. A valve actuator is coupled to the fluid control valve housing for setting of the fluid control valve in an unactuated ready state and for operating the fluid control valve automatically and/or manually. The assembly has a common supply port to supply fluid to the control valve and the actuator and a common discharge port connected to multiple devices that can place the system in an actuated state.

A manual reset actuator is disclosed, which includes a main drain, a diaphragm release aperture fluidly coupled to a flow control valve, an upper chamber, a control port, a control orifice, an upper chamber supply orifice, and a sealing assembly, which includes a button, and a plunger. A pressure in the upper chamber exerts a downward force on the plunger. A spring exerts an upward force on the plunger. The fluid in the upper chamber is released via the control orifice, which lowers the pressure in the upper chamber, decreasing the downward force exerted on the plunger. When the downward force is less than the upward force, the spring forces the plunger upwards into an open configuration, which unseals the diaphragm release aperture. When the upward force is less than the downward force, the plunger remains in a closed configuration, which keeps the diaphragm release aperture sealed.
