Definitions

  • a known, though not necessarily commonly known, electric regulator is the Tecno regulator from Hoerbiger-Origa Corp of Illinois, USA. which is designed for applications such as ultrasonic welding or medical equipment.
  • This regulator operates by actuation of a piezo member which controls gas pressure in an actuating chamber continuously vented into the regulator casing.
  • the regulator includes a diaphragm exposed on one side thereof to the pressure in the actuating chamber and on the other side to atmosphere.
  • the piezo member in the Tecno regulator is energised to allow gas flow into the actuating chamber, thus increasing the gas pressure in the actuating chamber and opening the regulator valve.
  • When output pressure exceeds set point the piezo member closes off the gas entry to the actuating chamber, the pressure in that chamber falling due to the continuous venting.
  • the regulator valve closes.
  • a valve member 28 has a valve stem 30 carrying an end plate 32 which, when the valve is closed, seals against the valve seat to close off the orifice but is spaced away from the valve seat when the valve is open.
  • the valve member further includes an actuating diaphragm 34 exposed at one side to the gas pressure in the downstream region 18 and at its opposite side to gas pressure in a chamber 36.
  • the chamber has an electronically controlled gas inlet valve 38, such as a silicon microvalve, communicating with the upstream region of the regulator and a gas outlet 40, preferably also an electronically controlled valve but alternatively a bleed hole, leading to the downstream region.
  • the diaphragm 34 forms part of the inner wall of the chamber.

Abstract

L'invention concerne un régulateur d'alimentation de gaz domestique comprenant une vanne de régulation (28) actionnée par diaphragme (34), lequel fonctionne sous l'effet d'une pression correspondant à la zone de pression peu élevée (18) et d'une pression de point de consigne dans une chambre (36). Des vannes électroniques (38, 40) contrôlent la pression de gaz dans la chambre (36). Un microprocesseur (42) règle la pression de point de consigne dans la chambre (36). Selon une variante, la pression qui règne dans la chambre s'oppose aux forces exercées sur la vanne depuis la zone de pression élevée. L'activation du diaphragme assure une grande vitesse de réaction tandis que la pression régnant dans la chambre dépend de fluctuations à long terme.
