In the diagram, what do the arcs with arrows represent?

In the diagram, what do the arcs with arrows represent? One is a straight arrow, another is an arrow indicating radians, and there’s also an air vent. I’d appreciate it if you could help me understand this, thank you

Solenoid valve, air flow direction when excited and not excited

Can they be matched one by one? Does the straight arrow indicate excitation or no excitation? What do the arrowheads in radians indicate? What does an air defense vent refer to?

When I-01 is at logic ‘0’, the pneumatic signal passes directly to the control valve diaphragm ; When I-01 is at logic ‘1’, the compressed air in the control valve diaphragm head is vented through the vent path.

The VENT arrow indicates that the port associated with the solenoid valve is the vent port; the arc-shaped arrow shows that the air is discharged through this vent port via the actuator’s nozzle. That is, during interlock, the actuator die gas is vented through a solenoid valve, and the control valve closes as part of the interlock mechanism.

It’s better to teach someone how to fish than to give them fish. Let’s learn together and make progress together. HG_T20505-2014: Functional symbols of process measurement and control instruments.pdf. Thank you, Zeyewangluo2010. Price: 1 wealth point
