Abstract: An automatic fire hydrant water supplying system provides hydrant supply water to a fire truck having a water pump; a water pump master intake valve; a water-supply fire hose, a pressure sensor upstream of the master-intake-valve, and a water-pump control system. The automatic fire hydrant water supplying system has a remotely-controllable hydrant discharge valve connectable to the hydrant and to the fire-hose. A remotely-controllable air bleed valve is in fluid communication with the master-intake-valve and the fire-hose. The water-pump control system determines whether a pressurized volume in the fire hose upstream of the master-intake-valve input port is air or water based on a difference in density between air and water as sensed by the pressure sensor and if the pressurized volume is air causes the air to be vented to atmosphere through the air-bleed-valve before opening the master-intake-valve to provide hydrant supply water to the water pump.

Abstract: A system and method for conveying a tool to a target sub within a tubular string having a number of subs. Each sub may include at least one ledge or shoulder in or on its interior surface that can be used as a latch stopper or stopper, for receiving and engagement with a latch. The subs may also have a latch deflector or deflector. In one embodiment, the latch deflector is a latch-deflection shoulder protruding into the internal diameter (ID) of the string for deflecting a latch, to be subsequently introduced, out of or into the latch-stopping shoulder. The distance between the latch stopper and the latch deflector, referred to as the “deflection radius,” may be used as an address that uniquely identifies each sub, and can vary from sub to sub.

Abstract: A hydrant drainage boot is installed around a water supply line and a frost-free hydrant to prevent dirt and debris from blocking the drainage port, and ensures unobstructed drainage of the hydrant. The frost-free hydrant has a linear riser pipe having a pipe top end and a pipe bottom end, a pivoting operating lever having a spigot a valve having a drain port, and a pipe connector. The hollow boot body has a first housing and a second housing attached to form a boot body with a boot cavity, base drainage slots, side drainage slots, water drainage louvers, raised louvers, and input and output ports. The hydrant drainage boot is enclosed around at least the valve, the pipe connector, a water supply line and a portion of the riser pipe of the frost-free hydrant.

Abstract: A device for flushing a hydrant includes a stem connected to a fluid valve of the hydrant and an actuation system including a biased translational system coupled to the stem, a compressed gas, and a normally-open gas discharge valve. An actuation system for flushing a hydrant includes a fluid, a piston assembly movable by the fluid, a manual bleed valve in communication with the fluid, and a biasing element at least indirectly biasing the piston assembly towards a stop position.

Abstract: 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.

Abstract: The aim of the invention is to block the water outflow from a light liquid separator comprising an outflow ascending pipe (1) with a lower inlet (3), and a horizontal output pipe (2). To this end, a blocking element (4) displaced by a float (9) is provided. The float (9) and the blocking element (4) are displaceably guided on a fixing element (11) that can be detachably associated with the water outlet (1).

Abstract: An improved outdoor hydrant-type water faucet comprised of a water control connector at the top section of a hydrant-type standpipe equipped with a water control connector adjustment fixture and a downwardly extending coupling rod at the bottom section of the hydrant-type standpipe, and a water input valve that opens and closes to vary flow volume. The feature of the present invention is that the hydrant-type standpipe bottom section consists of a wide-mouth sleeve section that provides for the installation therein of a higher specification water input valve having a greater flow volume rating, thereby achieving an increase in water output volume and a reduction in blockage, effectively relieving ice formation and consequent water obstruction due to low temperature outdoors.

Abstract: A system for providing access to a fire hydrant. The system includes an actuator extension having a first end and a second end spaced from the first end. The first end is configured to be mounted on an exterior location on the fire hydrant, so that the first end is operatively engaged with a valve actuator of the fire hydrant, the valve actuator being selectively rotatable to cause a valve of the fire hydrant to open and close. The second end is spaced from the first end and is configured to facilitate application of an externally-applied force and transmission of such force to the first end of the actuator extension.

Abstract: A irrigation hydrant particularly adapted for attaching to an above ground valve assembly. Comprised of a cylindrical body with an internally threaded centrally located hub and a gasket, mounted coaxially on a vertical stand pipe, having a valve plate with a coaxially rotatable screw and a handle assembly centrally located and attached to the valve plate for opening and closing the valve. The irrigation hydrant comprised of a of a cylindrical body assembly with one or more tubular pipe couplers. Including two or more mechanisms for releasably attaching to an standard above ground irrigation valve and a coaxially rotatable and slidable handle and yoke assembly for opening and closing the valve while hydrant is clamped to the valve.

Abstract: The present invention relates to an improved ball valve assembly which is adapted to be fitted into a water delivery device such as a spigot or fire hydrant. More specifically, the ball valve assembly is specifically installed and adapted for remote control. Such remote control enables the ball valve to be positioned at a location within the water delivery device to avoid damage. Thus, the remote control enables the ball valve to be resistant to cold weather or physical damage to the delivery device. The various components of the present invention, and the manner in which they interrelate, will be described in greater detail hereinafter.

Abstract: A control means for ground hydrants is disclosed for use in combination with a conventional freezeless ground hydrant having an elongated vertical housing with a valve means at the lower end thereof to control the inflow of pressurized water. The valve means includes an elongated control rod that extends upwardly through the housing. A fluid passageway extends through the housing and terminates in an exit port. The control rod for the valve means is spring loaded in a downward or closed position by a tension-adjustable spring secured thereto. A solenoid means is mounted upwardly of the rod and is operatively secured thereto. An electrical timer is connected in series with the solenoid. When the solenoid is electrically actuated, the solenoid will pull the rod upwardly to open the valve in the bottom of the housing. When the electrical timer de-energizes the solenoid, the spring adjacent the rod will cause the valve to close.

Abstract: An apparatus for attaching a fire hose to a fire hydrant and for facilitating remote operation of the hydrant actuator stem. A water supply module containing a length of conduit is coupled between a hydrant port and a fire hose. An articulated boom supports an upper motor assembly coupled to the actuator stem of the hydrant. A remote transmitter can be used to broadcast control signals to the water supply module to operate the motor assembly. The motor assembly rotates the actuator stem of the hydrant between fully closed and fully open positions. The apparatus frees a fire fighter normally stationed at the hydrant, permitting the fire fighter to engage in the initial fire fighting activities at the scene of a fire.
