초록 ▼

A solenoid actuator for a fluid flow valve comprises a closure member (64) adapted to engage a fluid flow orifice (16), and includes a magnetic plunger (46) under the control of a solenoid, for moving the closure member (64) into or out of engagement with the orifice (16). To assist the opening of the valve, a diaphragm spring (66) aids the downward force upon plunger (46) at changeover, being deflected during the upward stroke of plunger (46) and held deflected until changeover. The solenoid plunger (46) is stable at either end of its travel to maintain the selected state of the valve, change of state to open or close orifice (16) being by means of an magnetic pulse generated by solenoid coil (43), the plunger (46) being latched at closure by permanent magnets (32,34). The diaphragm spring (66) may form part of an assembly (62) including a membrane switch (70), responsive to the state of the valve, the assembly (62) fitting into the body of the closure member (64). Alternatively a reed switch responsive to magnetic flux may provide valve status indication. The use of a diaphragm spring to assist in valve opening, enables provision of an axially more compact, and electromagnetically more efficient actuator, able with appropriate intrinsic safety protection, to be enclosed within a gas meter housing to control an incoming gas supply under control of electronic switching circuits.

대표청구항 ▼

Solenoid actuator for a fluid flow valve, the solenoid actuator comprising: a closure member adapted to engage a fluid flow aperture external to the solenoid actuator; solenoid means having a movable plunger adapted to move the closure member into engagement with the fluid flow aperture; the closure member comprising a sealing surface to contact the fluid flow aperture and a diaphragm spring, within the closure member, to which the plunger is attached; the diaphragm spring being adapted to deform in the direction of travel of the solenoid plunger when the sealing surface has contacted the fluid flow aperture, to convey to the sealing surface, and to limit, the force exerted upon the sealing surface by the solenoid means, and to provide a force acting to displace the closure member from the fluid flow aperture when the force due to the solenoid means is removed. A solenoid actuator in accordance with claim 1 including a switch, the operative state of which indicates the position of the closure member relative to the fluid flow aperture. A solenoid actuator in accordance with claim 3 in which the switch is a membrane switch incorporated within the closure member.
