SOLENOID VALVE OPERATION INDICATOR

摘要

A solenoid valve operation indicator is provided to allow an operator to easily confirm the opening/closing state of a valve by rotating a needle by the magnetic force generated in the solenoid valve. A solenoid valve operation indicator includes a housing(21), a needle(22), a magnetic body(30), and a spring(40). The housing is fixed to the body of the solenoid valve. The needle is rotated by a hinge shaft of the housing. The magnetic body is fixed to one end of the needle of the hinge shaft. One end of the spring is fixed to the housing and the other end thereof is fixed to one end of the needle. The needle is rotated by generation and diminishment of a magnetic force according to whether a power source is applied to the solenoid valve.
