  • Patent number: 8794595
    Abstract: Diaphragm valve with internal leak detection and improved external leak sealing performance. In diaphragm valves comprising diaphragms that have shields and backings, a rigid seal plate interposed between the shield and backing prevents peripheral regions of the shield from cold-flowing into the backing, despite the compression forces produced by tightening the fasteners that secure the diaphragm to the valve's bonnet assembly and body. An access port passing through the seal plate provides an interface between a void located between the shield and the backing and a breach detector. The breach detector is configured to detect pressure, volume, moisture or mass deviations in fluid disposed in the void, and the deviations indicate whether there's a rupture in the shield or the backing. The breach detector can be connected to an alarming device or signaling system to provide warnings and alerts to valve operators, process control panels or data communication networks.

  • Patent number: 8561453
    Abstract: A method and system for automatically calibrating all pressure sensors in a hydrogen storage system for a fuel cell vehicle. A pressure regulator in the hydrogen storage system, which has much greater accuracy at low pressures, is used to calibrate the high-range pressure sensors used in the hydrogen storage system. This calibration can only be done when the pressure regulator is in a fully open position. In such a condition, the pressure sensors can be calibrated to the regulation pressure value of the regulator, thus greatly improving the accuracy of the readings of the high-range sensors at the low end of their range. The calibration can be performed during fuel cell operation under certain circumstances, performed during a programmed shutdown sequence, or performed in a service procedure.

  • Patent number: 8474474
    Abstract: A method of diagnosing pressure boundary integrity of a control includes choosing a control valve having a valve body, determining a velocity profile within the control valve, choosing an area of the velocity profile, choosing a surface on an exterior of the valve body at or adjacent to the area, forming a pad on the exterior surface overlying the point, applying a testing device to the pad, and measuring a reference thickness of a wall of the valve body through the pad using the testing device. The method further includes applying the testing device to the pad at a time subsequent to measurement of the reference thickness, measuring a first thickness, and comparing the first thickness to the reference thickness. The comparison of the first thickness to the reference thickness can be used to calculate the amount of valve body wall lost during using and the remaining life of the control valve.

  • Publication number: 20120211097
    Abstract: A valve that can be actuated by a position controller via a drive, wherein the position controller has a housing and is fastened to the valve by the housing. A first temperature sensor and a second temperature sensor are attached on or in the housing. As a result of the position of both sensors, the temperature measured using the first temperature sensor is more readily influenced by the valve and the temperature registered by the second temperature sensor is more readily influenced by the environment. If a gas leak occurs in the valve, a temperature difference occurs that is evaluated for diagnosis of a leak. The diagnostic system is particularly easy to minor implement with minimal effort.
