摘要： 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.

摘要： The present invention provides for a device or feature that incorporates a technique or means for flow measurement in a fluid flow system. By way of example, a contoured insert may be specifically calibrated to the pipe line size to ensure the desired accuracy of the flow measurement, irrespective of pipe length between the device and other fluid system components that would negatively influence other flow rate measurement devices. This in turn reduces the total number of components needed in a system.

摘要： A suction diffuser or arrangement is provided featuring a main suction diffuser body and a flow conditioning arrangement. The main suction diffuser body is configured with an inlet to receive an incoming fluid flow, an interior cavity to receive the incoming fluid from the inlet, and an outlet to receive the incoming fluid from the interior cavity and provide an outgoing fluid. The flow conditioning arrangement is configured in relation to the inlet and also comprises a flow conditioning portion having at least one inwardly contoured surface, configured to extend into the interior cavity, diffuse the incoming fluid passing from the inlet into the interior cavity, and provide a flow conditioning that produces a uniform flow of the outgoing fluid by directing the incoming fluid towards the outlet, based at least partly on a contoured design corresponding to the at least one inwardly contoured surface.

摘要： A valve includes a body having an upstream port to measure upstream pressure and a downstream port to measure downstream pressure, both ports configured re a common axis, and includes a ball arranged in the body to rotate re the common axis between open and closed positions to allow for fluid flow/non-fluid flow. The ball has a calibrated member having a calibrated orifice to allow fluid flow and has a flow coefficient, an upstream pressure tap located upstream of the calibrated orifice and in fluidic communication with the upstream port to measure upstream pressure when in the open position, the upstream pressure tap angled re the common axis, and a downstream pressure tap located downstream of the calibrated orifice and in fluidic communication with the downstream port to measure downstream pressure when in the open position, the downstream pressure tap angled re the common axis, so conditions of fluid flow are determined based on a measured pressure differential between upstream and downstream pressure taps re the flow coefficient of the calibrated orifice when in the open position.

摘要： A balance or flow limiting valve features a valve body/member having a flow rate indicator/scale containing setting having printed flow rates calibrated in units of measure in volume per time increment between a minimum flow rate position (MIN) and a maximum flow rate position (MAX); and a knob/handle having a position indicator and being moveable to any continuous position on the flow rate indicator/scale between MIN and MAX in response to a user applied force, where the relationship between the flow rate indicator/scale and the position indicator is based on calibrated flow characteristics of the balance or flow limiting valve. The user can set an exact desired flow rate in one operation by moving the knob/handle to a desired position between MIN and MAX without consulting a printed flow curve or balance calculator to determine the desired exact flow rate.

摘要： A condition monitoring device for monitoring machinery includes a combination of on-board sensors and a condition monitoring module. The on-board sensors include modules for non-contact temperature, magnetic flux and 3-axis vibration sensing of the machinery. The condition monitoring module provides a condition monitoring signal containing information about an operating condition of the machinery, based upon a data synthesis condition monitoring technique that synthesizes non-contact temperature, magnetic flux and 3-axis vibration sensed data received from the combination of on-board sensors, determines a current operating condition of the machinery, and compares the current operating condition and the baseline operating condition of the machinery.

摘要： A pumping system featuring a pump, motor, a bearing assembly, integrated data acquisition system and combined programmable logic controller (PLC), data acquisition and modem. The pump couples to a pump shaft that responds to a pump shaft force to pump a liquid. The motor couples to the pump shaft, responds to VFD/VSD control signaling and provides the pump shaft force to drive the pump shaft. The bearing assembly includes a bearing with the pump shaft arranged therein and couples the pump and the motor. The variable frequency/speed drive (VFD/VSD) receives PLC control signaling and provides the VFD/VSD control signaling to drive the motor. The integrated data acquisition system responds to PLC data acquisition signaling, and provides integrated data acquisition system signaling containing information about an integrated set of pumping system parameters related to the pump, the bearing assembly, the motor and the VFD/VSD in the pump system. The combined programmable logic controller (PLC), data acquisition and modem provides the PLC data acquisition signaling and receive the integrated data acquisition signaling, provides PLC data acquisition modem signaling that exports performance data to the Internet to allow remote manual monitoring of the pump system, and provides the PLC control signaling to control the VFD/VSD and operate the pumping system as a controlled, closed loop system.

摘要： A contoured check valve disc features a pivot portion and a check valve portion. The check valve portion is attached to the pivot portion, and has two sides, a first side to respond to the fluid flow in a first direction and move the check valve portion away from a fluid opening to the one or more open positions depending on the fluid flow to allow the fluid to flow through the fluid opening, and a second and opposing side to respond to fluid flow in an opposite direction through the fluid opening and move the check valve portion towards the fluid opening to the closed position to seal the fluid opening and stop fluid flow. The check valve portion a near-sloped portion formed nearest to the pivot portion, having a near-sloped contoured surface curving away from the pivot point to a first point of inflection with a first curvature, and a far-sloped portion formed farthest from the pivot portion, having a far-sloped contoured surface curving away from the point of inflection towards a farthest point away from the pivot portion with a second curvature that is less curved or bent than the first curvature, the near-sloped portion and the far-sloped portion combining to form a combined surface having a contoured pressure/force distribution on the first side to respond to the fluid flow and move the check valve portion away from the fluid opening.
