  • Patent number: 11035106
    Abstract: A fully serviceable frost proof mixing hydrant for supplying water at various temperatures to the exterior of a building. The mixing hydrant includes hot and cold water inlets and a chamber in which the water is mixed based on the position of a cammed wheel acting on a pair of poppets. These poppets act as temperature regulators and check valves to prevent cross-flow leakage and/or contamination. The mixing hydrant includes an inside tube or flow sleeve for delivery of water to an outside body tube in communication with a spout on the head of the hydrant. The flow from the inside tube to the outside body tube reduces turbulence and provides a better outlet flow from the spout. Flow control and temperature control are independent allowing the user to set the flow as desired then adjust the temperature as desired without affecting the flow.

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: 8997789
    Abstract: An apparatus for preventing backflow and contamination, and detecting by-pass leaks in a flow control arrangement is disclosed. The apparatus includes a vent line connecting a sweep gas source and a vent. Constant process-inert gas flows from the source through the vent line into the vent. The vent line is connected with the flow control arrangement. Any leakage in the flow control arrangement is channeled to the vent line and swept into the vent along with the sweep gas. As a result, pressure in the flow control arrangement cannot build up and leakage backflow is prevented. A flow switch may be disposed on the vent line for detecting leakage. The sweep gas flow rate is controlled at a constant level that is inadequate to actuate the flow switch and keeps the flow switch ready to actuate by any superimposed leakage. The flow switch detects a leakage when it actuates.
