  • Patent number: 11458655
    Abstract: A method of finding a target conveying capacity of a pumping includes a temperature-control flow through a temperature-control channel carried out according to a control variable by using a throttle as an actuating element such that a temperature-control volume flow remains substantially constant. A conveying flow of the pumping system is measured, and a pump starting from a starting conveying capacity independent of the control of the temperature-control volume flow is driven such that a conveying capacity of the pumping system is reduced to a reduced conveying capacity. Then, a check is made to find whether the conveying flow remains substantially constant and, if this is the case, the reduced conveying capacity is determined to be the target conveying capacity. If this is not the case despite the control of the temperature-control volume flow, the starting conveying capacity is determined to be the target conveying capacity.

  • Patent number: 10626585
    Abstract: The Sewer Back-flow Preventer Monitor is a device designed to be an add-on to a sewer back-flow preventer valve, otherwise known as a backwater valve. It offers a higher level of protection against flood than that which is offered by a sewer backwater valve without any such device. It uses digital and/or analog electrical sensors, magnetically linked to the flapper, to determine the precise flapper position of a backwater valve and will warn a user of a municipal sewer backup and or back-flow. As well, it will provide an alert when a cleaning is necessary and informs users when a sewer backwater valve has successfully closed during an event. It is a cost effective solution.

  • Patent number: 10502455
    Abstract: A system to reduce standby losses in a hot water heater is presented. The system utilizes a dual safety relay valve between the combination gas controller and the burner. The dual safety relay valve bypasses gas to a rotary damper actuator valve to position a damper flapper valve located over/inside the flue pipe. Once the flapper valve has opened to ensure combustion, the gas is allowed to flow back to the dual safety relay valve. Some of the bypass gas may be diverted to boost the pilot or to supply a booster. The dual safety relay valve is then opened to allow the gas supply to the burner. Once the burner is turned off, bypass gas bleeds out of the rotary damper actuator valve to close the damper flapper valve to reduce standby losses through the flue pipe, and to allow the dual safety relay valve to close tightly.

  • Patent number: 10443880
    Abstract: The present invention allows for a combination valve in a hydronic HVAC system that functions as an isolation valve; a check valve; and as a device for measuring fluid parameters, such as flow rate, pressure, and/or temperature, and also allows for the isolation valve to be configured in the field to be mounted either in a straight 180° or an angled 90° orientation, as well as at an intermediate angle. The new combination of isolation valve, check valve, with embedded sensors for flow rate, pressure, and/or temperature measurement provides a more compact product envelope that achieves space savings, e.g., by eliminating the need for separate components in an HVAC system, such as separate isolation valves, check valves, flow meters, pressure gages, and/or thermometers.

  • Patent number: 10145574
    Abstract: The vent port employs a pair of mated housing parts that define a space for two flap valves. Each flap valve is formed of an aluminum bracket with an aperture for the passage of air and a silicone flap that closes over the aperture. The flap valves are oriented so that gravity enhances the closing of the flaps. Resistors are mounted on the brackets to heat the brackets at a low wattage. In one embodiment, the flap valves are vertically arranged over each other. In another embodiment, the flap valves are horizontally disposed in criss-crossing relation.
