COMBINATION ISOLATION VALVE AND CHECK VALVE WITH INTEGRAL FLOW RATE, PRESSURE, AND/OR TEMPERATURE MEASUREMENT

摘要

A combination valve includes an isolation shutoff valve to prevent a fluid flow; a check valve to prevent backflow and gravity circulation of fluid flow; a pressure sensor to sense a pressure measurement of fluid flow and determine pressure sensor signaling containing information about a sensed pressure measurement; a temperature sensor to sense a temperature measurement of fluid flow and determine temperature sensor signaling containing information about a sensed temperature measurement; and a flow measurement sensor to sense a flow measurement of fluid flow and determine flow measurement signaling containing information about a sensed flow measurement. The pressure sensor, temperature sensor and flow measurement sensor are all embedded and preassembled in the combination valve with the isolation shutoff valve and the check valve as part of one integral composite unit or component, so as to form a combination isolation valve and check valve with integral flow rate, pressure and/or temperature measurement.
