Quick exhaust valve
Thread Content
It’s a valve for rapid exhaust, similar to a solenoid valve. What is its working principle? One end of it is connected directly to the air duct, while the other end is connected to the outlet of the solenoid valve; it’s used to accelerate exhaust. What is its working principle?
It functions like a large-diameter exhaust port; during exhaust, it acts in a manner similar to the exhaust port of a solenoid valve. Under normal conditions, the pressure for exhaust is provided by the output side of the solenoid valve. When the solenoid valve loses air supply, rapid exhaust occurs, with the gas from the cylinder passing directly through the rapid exhaust mechanism without going through the solenoid valve’s exhaust port.
It seems there is a line that connects directly from the gas source to the quick exhaust valve. What is its purpose? Thank you for your answer
I’m sorry, I’ve really never seen this before. If the gas supply is connected directly, it’s not possible to cut off the gas flow, and thus the quick exhaust system cannot function either. It might simply be a connection method designed to protect the production equipment or processes in case of a gas supply failure. I haven’t encountered it yet.
This is a signal from the positioner, used to adjust the pressure of the starting accelerator
No diagram was provided, but I guess it works like this: The air supply is connected to the quick-release valve, providing air for the cylinder’s operation, while the air coming out of the solenoid valve is used to switch the air path of the quick-release valve. For example, if the solenoid valve loses power, there will be no air pressure at its outlet; in that case, the quick exhaust valve takes over to exhaust the air (the air stored in the cylinder), and at this point the air supply is \"cut off\" by the quick exhaust valve. When the solenoid valve is powered on, the quick-release port becomes “closed”, and air from the air supply enters the cylinder again. @jiaguoyun
What does that mean? Are you referring to quick sort or an amplifier?
Under normal conditions, the starting pressure is provided by the output terminal of the solenoid valve; when the solenoid valve loses air pressure, a rapid exhaust action occurs, and the gas in the cylinder is discharged directly through the rapid exhaust valve, without passing through the solenoid valve’s exhaust port
