Title:
弁アクチュエータ
Document Type and Number:
Japanese Patent JP5820876
Kind Code:
B2
Abstract:
The valve actuator (1) includes a housing (2), a motor (4) coupled to the valve, wherein rotation of the motor (4) changes the position of the valve from a first position in which fluid flow may occur along at least one path and a second position in which fluid flow is either blocked or may occur along at least one second path, said motor (4) being normally supplied with electrical power from a main source of electrical power, at least one sensor (24,132) configured to detect the position of the valve and/or the valve speed, a switch (16) controlling the delivery of electrical power to the motor (4), and a power circuitry (19) connected to the switch (16). The valve actuator further includes a controller (20) connected to the at least one sensor (24,132) and to the power circuitry (19), said controller (20) collecting in real time data relative to the position and/or the speed of the valve and data relative to the power setting, calculating the position and/or speed correction in pro rata to errors between the collected data relative to the position and/or the speed of the valve and collected data relative to the power setting, and sending a new power setting to the power circuitry (19), wherein the power circuitry (19) amplifies the controller signal.
