  • Patent number: 9353878
    Abstract: A dual plate backflow and breakaway check valve that features a warning system to alert individuals when fire hydrants are dislocated. The dual plate check valve comprises an upper surge protection valve assembly and a lower backflow protection valve assembly. When fire hydrant or pipes conveying fluids are damaged, the locking mechanism enables a plurality of upper witness stream holes to generate at least one plume of fluid to indicate and readily visualize location of damage and allows an upper barrel assembly to operate in a closure mode. In this mode, a high pressure spray of fluid emits from the upper valve barrel and an optimum inclination of the lower portion of the upper valve barrel enables the upper witness stream holes to collide with an inner side wall of the upper valve barrel which causes the plurality of upper witness stream holes to disperse into a warning signaling mist.

  • Publication number: 20140305516
    Abstract: An embodiment wall hydrant includes a reservoir, conduits containing an operating rod assembly and a service rod assembly, and a fluid outlet with a hose connector. The service rod assembly allows water supply to the hydrant to be shut-off from the front of the hydrant which allows servicing of the hydrant without requiring water shut-off to all or a portion of the water supply to the building. Embodiments include a vacuum relief dual check valve assembly at the fluid outlet which prevents backflow of water into the hydrant. Embodiments include a box which protects the hydrant controls.

  • Publication number: 20140137949
    Abstract: An insertable backflow preventer is presented. The backflow preventer is provided with a cylindrical housing. The housing has a flow transition zone, a proximal orifice/ball seat, a ball with a specific weight that equals or is close to the specific weight of the surrounding fluid, and a distal retaining screen. The housing can have a flange provided on the outside of the housing at one end to facilitate securing the valve in a pipe. The valve is self-cleaning, can be placed in any orientation in a pipe and has low hydraulic head-loss. The valve's unique cost-effective design provides for easy and relative quick installation, eliminates the need to reconfigure existing plumbing, and can be performance tested remotely. Properly installed, it can dramatically improve the security of, for example, potable water sources in a building or other context, and inasmuch as when installed it is not visible, it is tamper proof.

  • Patent number: 7156119
    Abstract: A hydrant knock-off combination flow stop valve and backflow check valve, mountable between water system riser and a wet-type hydrant having a breakaway flange ring. The vertical valve has a bulbous, cylindrical outer wall having an upper flange connecting to a wet-type hydrant by a break ring and a lower flange connecting to a system riser pipe. One embodiment has radial vertical vanes defining a central cylinder coaxial with the valve and acting as guides for a movable valve element to travel vertically up and down. The lower flange a seat, acting as a check valve with the valve element. The valve has a restraining cage keeping the valve element from engaging an upper seat.

  • Patent number: 5218987
    Abstract: A method and apparatus are disclosed for protecting a water distribution system from water surge damage which otherwise might result if one of its valves is suddenly opened or closed. The outlet of the shut-off valve and the inlet of the hydrant valve of one outlet of the system are excavated, and a specially designed tap including an airtight reservoir is inserted between and connected to them. When the tap is installed, the reservoir is preferably oriented to extend perpendicularly upward, so it normally will be at least partially filled with air in use. Preferably, no further joints separate the shut-off valve and the hydrant valve. Finally, the shut-off valve, the hydrant valve, and the tap are preferably buried to a depth beneath the frost line, if the hydrant is exposed to a climate where the ground is subject to freezing. A water distribution system having the previously described elements at each outlet is also disclosed.

  • Patent number: 4393891
    Abstract: The present invention relates to a device for periodically rinsing a water cock countersunk in the ground. A drainpipe is connected between the water cock and a closing member of an extension piece. The drainpipe includes a valve body which is opened by the water pressure prevailing in the extension pipe when the water cock is initially opened. After a predetermined period of time the valve body is closed. Thus, the present invention ensures that after the water cock is opened dirt is flushed away through the drainpipe which is subsequently automatically closed after a predetermined time. After the drainpipe is closed, a valve member connected to the extension pipe can be opened and only pure water will be supplied.
