    Abstract: A thermally actuated valve employs a plunger and bore valve configuration. A thermally expansible wax actuator has an axial length that changes in response to the temperature in a cavity of the valve. At temperatures above a predetermined set point, the actuator produces axial force sufficient to extend the length of the actuator against a return bias and project the plunger and seal into the bore, closing the valve. The plunger defines a pressure relief fluid flow path from the valve cavity to the valve outlet. A pressure relief valve is arranged in the plunger and is responsive to pressure in the valve. The pressure relief valve opens to relieve pressure above a pre-determined level. The thermally actuated valve and the pressure relief valve are coaxial and employ a common outlet.

Each water storage tank has its own microprocessor that controls the operation of the storage tank so that each storage tank can operate either as a stand-alone storage tank or can be integrated into a series or a daisy chain of storage tanks. Each individual storage tank monitors its water level, its temperature, and its flow rate. When a risk of freezing exists, based on time and temperature, the storage tank can dump water. When the water in the storage tank is approaching stagnation, based on flow rate and time, the storage tank can dump water. When a storage tank is part of a daisy chain of storage tanks, each individual tank monitors not only its own water level but also the water level of the next downstream storage tank and pumps water to the downstream storage tank as required.

    Abstract: The present invention provides a flow control apparatus and method. In accordance with the present invention, the flow control apparatus comprises a thermostat that automatically actuates valve to enable water to flow through the valve when the temperature of the air or water is at or near the freezing temperature of water (32° F.). When the temperature of the air or water rises above freezing, the thermostat causes the valve to close, thereby preventing water from flowing through the valve. Therefore, when the apparatus is coupled to an end of a water conduit, such as a water spigot or hose, water is allowed to flow through the conduit when the air or water temperature is at or near freezing to prevent the conduit from bursting due to water freezing and expanding within the conduit.

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.

  • Publication number: 20040200524
    Abstract: The present invention provides a flow control apparatus and method. In accordance with the present invention, the flow control apparatus comprises a thermostat that automatically actuates valve to enable water to flow through the valve when the temperature of the air or water is at or near the freezing temperature of water (32° F.). When the temperature of the air or water rises above freezing, the thermostat causes the valve to close, thereby preventing water from flowing through the valve. Therefore, when the apparatus is coupled to an end of a water conduit, such as a water spigot or hose, water is allowed to flow through the conduit when the air or water temperature is at or near freezing to prevent the conduit from bursting due to water freezing and expanding within the conduit.

    Abstract: A freezeless wall hydrant has a fluid inlet end connected to a source of pressurized water, and a fluid outlet end. A check valve is placed in the bore of the valve body and is spring loaded to open only when extreme water pressure within the inlet valve lifts a spring loaded piston element to permit the highly pressurized water to move through the bore in the valve body and be relieved as it escapes rearwardly into the original source of pressurized water.

  • Patent number: 6439260
    Abstract: Electrical control circuitry is provided for normally maintaining an electrically controlled water supply valve in an open condition and an electrically controlled water drain valve in a closed condition when a home is occupied and for arming the system by shutting off the water supply valve and for maintaining the water drain valve in an open condition. This action prevents pipe bursting and flooding, particularly during the winter, when a single manually operated conspicuously located switch is opened to arm the system upon departure from the home for an extended period. Should the home owner forget to arm the system, an electrical power interruption, which often can disable heating systems, causing pipe bursting and flooding, will automatically arm the system upon a power failure and the supply valve remains shut and the drain valve remains open until the homeowner returns and resets the system with a pushbutton switch.

  • Patent number: 6427712
    Abstract: A novel shape memory alloy (SMA) actuator which responds to changes in ambient temperature. The actuator is capable of operating bidirectionally over a smaller temperature range than conventional SMA actuators by taking advantage of the R-phase characteristics of the SMA material. A coiled SMA spring 14 is provided with an enabled R-phase by limiting recoverable strain in the SMA material to less than about 1 percent. The force of the SMA spring 14 is counteracted by a non-SMA spring 15. The stronger of the two springs 14, 15 controls the position of an actuating element 13, with SMA spring 14 being the stronger spring while in its austenitic phase and being the weaker spring while in its R-phase. Triggering the actuator with entry into the R-phase rather than the martensitic phase during cooling reduces the hysteresis normally associated with an SMA actuator, allowing the actuator to react bidirectionally to smaller changes in ambient temperature.

  • 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.
