  • Patent number: 8578959
    Abstract: The apparatus and method of the invention provides for a rinse valve for controlling the flow of rinse fluid to a vacuum waste receptacle. The rinse valve comprises a primary rinse fluid flow path and a poppet assembly intersecting the primary rinse fluid flow path. The rinse valve also comprises a solenoid-driven fluid control device having a solenoid armature movable between an inactive state in which the armature engages the poppet assembly to block flow of the rinse fluid through a poppet channel and an active state in which the solenoid armature is disengaged from the poppet assembly to allow flow of the rinse fluid through the poppet channel to raise the poppet assembly, permitting the flow of the rinse fluid through the primary rinse fluid flow path and out of the valve, the armature being located at all times out of the primary flow path of the rinse fluid.

  • Publication number: 20100195991
    Abstract: An on demand tankless water heater system that is capable of quickly delivering water within a desired temperature range. The tankless water heater provides a hybrid heating method that contains a primary heating system and a secondary heating system disposed in a buffer tank that cooperate to facilitate control of output water temperature during water usage. A pressure differential switch detects low flow demand and allows the secondary heating system to provide immediate heating to the water. This secondary heating system provides a faster temperature response and fine tuning of output water temperature.

  • Patent number: 7654280
    Abstract: An anti-freezing hydrant is provided with a hollow valve rod of which a back end is provided with a lump formed with an oblique cone where a water leakage hole is formed communicating with the valve rod. A one-way valve is provided in a inner water inlet in a valve chamber of a valve and comprises a rubber cushion being made of a soft rubber and thus elastically suppressing the inner water inlet. The bore of a back pressure stopper in a back pressure is a complement of an inner inclined cone with the oblique cone. Thus, the rubber cushion may enhance the capability of sealing of the valve. Further, the back pressure stopper may also be a good sealant for the inclined cone.

  • Patent number: 6883534
    Abstract: A freezeless wall hydrant has a normally horizontal fluid inlet tube with an interior end and exterior end. A hollow valve fitting is rigidly secured to the interior end of the inlet tube for a connection to a source of pressurized fluid. A valve seat is located on an interior end of the valve fitting. A valve body is longitudinally movably mounted in the inlet tube adjacent to the valve fitting. A pressure relief valve is mounted on the inlet tube between the interior and exterior ends thereof so that if residual water within and adjacent the exterior end of the inlet tube freezes and exerts pressure on residual fluid within the inlet tube adjacent the interior end thereof, the pressure relief valve will actuate to purge some of the high pressure fluid to decrease the pressure being exerted by such fluid to the interior of the inlet tube.

  • Patent number: 6857442
    Abstract: A freezeless wall hydrant has a normally horizontal fluid inlet tube with an interior end and exterior end. A hollow valve fitting is rigidly secured to the interior end of the inlet tube for a connection to a source of pressurized fluid. A movable ball is located with a fluid conduit that extends from the interior of the inlet tube to the location of the potable water source. When the water pressure inside the inlet tube increases because of the presence of ice, the high pressure of such water moves the ball to open fluid flow of the high pressure fluid to the source of potable water which will be at a lower pressure, thus reducing the fluid pressure within the inlet tube and saving it from rupture.

  • Patent number: 6830063
    Abstract: A freezeless wall hydrant is provided that has an elongated inlet pipe comprised of a hollow tube. The tube is connected to a valve and fitting assembly on its inner end for connection to a source of water under pressure. On the outer end, the tube is connected to an adjusting element with an outlet port that is associated with the valve and fitting assembly to open or close the tube to fluid flow and allow for fluid flow out of the tube when the valve is in the open position. The tube is comprised of a flexible material that enlarges in diameter in an area along its length when it is subjected to trapped fluid therein under high pressure so that the tube will not rupture. The tube returns to its normal diameter after the high fluid pressure therein is abated.

  • Patent number: 6363960
    Abstract: This invention relates to a frost protection device for preventing sections of water pipes which are in danger of being affected by frost from freezing up. Said frost protection device consists essentially of a pressure control valve with a piston-type valve body which moves axially in a cylindrical housing. The pressure control valve also interacts with a valve seat which is connected to the section of pipe being monitored. According to the invention, the valve seat is located outside of the flow path defined by the section of pipe, in a branch which constantly communicates with said section of pipe.

  • Patent number: 5785073
    Abstract: According to the present invention, water regulation assemblies disposed in the water supply path of conventional fixtures are modified to include a pressure relief assembly which permits release of water under elevated pressures. A normal shut-off seal included in the water regulation assembly may be modified to release water in response to elevated pressure even when the seal is placed in a shut-off position. In particular, mating components included in the seal assembly are modified to separate at the elevated pressure. The seal may also be by-passed by a pressure relief water path which opens in response to elevated pressures. These features permit relief of elevated pressure in water supply lines which might otherwise produce a burst event within the water supply lines. In sliding plate type faucets where a seal is created by pressing of two plates together, pressure relief according to the present invention is obtained by permitting separation of the plates under elevated pressure.

  • Patent number: 5715855
    Abstract: A temperature-actuated valve includes an elongated housing having anterior and posterior segments, the anterior segment being connected to an outdoor water supply. A valve within the anterior segment opens in response to freezing temperatures, defining a fluid path that allows water from the outdoor water supply to flow through one or more discharge ports; and which closes when the temperature rises above freezing. The valve generally includes a piston movable within the housing and having a valve head, and a valve seat formed in the anterior housing segment; seating of the valve head against the valve seat closes the discharge port(s). The device also includes means for conducting water from the anterior housing segment to the posterior housing segment, the latter comprising an expansion reservoir for freezing water. When water freezes, its expansion moves the piston so as to unseat the valve head and thereby allow water to be discharged through the discharge port(s).

When installed in a water supply line for a building structure that is subject to freezing and thawing conditions, the valve shuts off the supply of water to the building structure during the freeze and prevents further supply of water to the building after the thaw occurs so that the interior of the building is not damaged by flooding.
