Combination isolation valve and check valve with integral flow rate, pressure, and/or temperature measurement with wireless power

Abstract

A wirelessly powered system includes a wirelessly powered combination isolation valve and a check valve for a hydronic system, having a positive shut-off isolation valve configured in the hydronic system to prevent fluid flow, including to allow for maintenance of the hydronic system, a check valve configured in the hydronic system to prevent backflow and gravity circulation which can harm the hydronic system, and a combination of one or more sensors configured to sense a corresponding combination of one or more pressure, temperature or flow measurements of the fluid flow in the hydronic system and provide sensor signaling containing information about the corresponding combination of the one or more pressure, temperature or flow measurements sensed of the fluid flow in the hydronic system;and an onboard wireless power receiver configured to receive wireless power signaling, and provide power to energize the combination of the one or more sensors.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Provisional Application Serial No. 62 / 217,355 (Agency Docket No. F-B&G-X0023 / / 911-19.23-1), filed September 11, 2015, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a valve; more particularly, the present invention relates to a combination valve for a hydronic heating, ventilation and air conditioning (HVAC) system. Background technique [0004] Today's hydronic HVAC systems increasingly utilize variable frequency drives and variable speed pumps. Most of such known systems require shut-off and check valves, and flow measurement equipment installed permanently, or temporarily, to verify system flow rates. When permanently installed in a hydronic HVAC system, these known flow measurement devices take up additional space and increase system head loss. A significant amount of additional pipe length may be...

Problems solved by technology

Electrical wiring from a hard-wired power supply to a combination of one or more sensors may cause or contribute to associated electrical wiring confusion

The associated electrical wiring confusion for connecting to such a hardwired power source can cause and create electrical and mechanical safety hazards throughout the HVAC system (eg, especially over time)

[0008] By way of further example, since the sensor needs to be coupled or connected to electrical wiring, such electrical coupling or connection used may often be prone to failure, unreliable in the long run, and can easily be attributed, for example, to moisture, dirt , ambient atmospheric conditions and motion (including vibrations associated with certain HVAC applications and / or environments) and self-damage over time

Furthermore, such sensors, especially if not sealed (e.g. hermetically), may also damage themselves over time, e.g. due to exposure to moisture, dirt and ambient air conditions

In addition, such sensors themselves may also deteriorate over time due to accidental and undesired movement from electrical wiring, such as by being disturbed, pulled and ripped / broken in any such HVAC application and / or environment. damaged
