  • sma actuator for gas combi boiler Diverting Valve
    Sensors and Actuators A-physical, 2006
    Co-Authors: Guglielmo Magri, Manuel Romagnoli, Costanzo Di Perna
    Abstract:

    Abstract This article deals with a three way Diverting Valve for heating boilers using a shape memory alloy material to move its actuator. This project was realized by the Research & Development Department of MTS (Merloni Termosanitari) together with the Energy Department of the University of Ancona; this device is protected by a European patent. As is well known, the three way Diverting Valve inside a heating boiler has the function to shift hot water flow coming from the primary heat exchanger either towards the sanitary circuit or the domestic heating system, depending on the demand. The idea of a shape memory alloy to realize the actuator movement of the three way Valve represents a good alternative to traditional actuator moving systems using a electric motor. A shape memory alloy is characterised by the ability to recover a pre-macroscopic deformation during a phase change caused by heating; moreover the deformation recovery brings to a increase to the mechanical properties of a shape memory alloy. In this article, we will present in detail the Valve functionality, the equations we used for the dimensioning, and the description of the most important tests on the device to verify its efficacy and reliabililty.

  • ELECTROMAGNETICALLY ACTUATED GAS Diverting Valve USING LTCC TAPE NSF Summer Undergraduate Fellowships in Sensor Technology
    2011
    Co-Authors: Advisors D, J. J. Santiago-aviles, P. Espinoza
    Abstract:

    This research attempted to fabricate a gas-Diverting Valve using LTCC technology for the emerging field of meso-scale devices. A photolithographic process for patterning Low Temperature Co-Fired Ceramic (LTCC) tapes utilizing DuPont Green Tape ™ tape coupled with DuPont Riston ® 9015, a dry photoresist, is described in detail. Based on the device design, calculations determining the theoretical resistance and magnetic flux were made. These numbers will determine the voltage necessary to run the device once built. Although the device was not constructed since the resolution of the dry photoresist system was being pushed led to difficulty in etching the tape, lamination and development techniques of the Riston ® were perfected, and insights into the composition of the tape prior to and after etching were made. Suggestions for improvements in the process are given, as well as thoughts on what should be the next step in this research. 1
