Description

Description:

The 110VAC AST solenoid valve AM-501-1-0148 belongs to the ETS actuator and is a solenoid valve installed on the integrated block. It is mainly used to execute signals sent by superiors and receive hydraulic flow from the daily solenoid valve system. The 110VAC AST solenoid valve AM-501-1-0148 is used for the emergency trip control block of the power plant ETS system. ETS is a protective device for the emergency trip system of the steam turbine, which receives alarm or shutdown signals from the TSI system or other systems of the steam turbine generator set, performs logical processing, and outputs indicator light alarm signals.

Working principle of hydraulic 110VAC AST solenoid valve AM-501-1-0148: There is a closed chamber inside the hydraulic solenoid valve, with through holes opened at different positions. Each hole is connected to a different oil pipe, and hydraulic oil enters a different drain pipe. Then the piston of the oil cylinder will be pushed by the pressure of the oil, and the piston will drive the piston rod. The piston rod will drive the mechanical device, thereby controlling the mechanical movement by controlling the current of the electromagnet.
