Thermal high-level self-protecting valve
Thread Content
The air line was connected, the valve closed on its own; manually attempting to open it on site didn’t work. Once the air line was properly connected and automatic mode was activated, the air line was shut off, but the valve did not move – the control room continued to operate in automatic mode
Such valves should be divided into two parts: the valve body part and the valve actuator part that controls the operation of the valve. The actuator is divided into a pneumatic part and an electrical signal part. I guess your problem lies in not understanding the control principle of this type of valve. It is recommended to read the instruction manual more often, and to express issues in a relatively standardized manner. Instrument air supply, instrument air – the terms related to air lines seem too specialized. It’s better to check the manual/automatic operation settings; be sure to read the instructions thoroughly before making any decisions.
Is the valve position incorrect? Or the mechanism of action is incorrect.
Position maintenance means staying at the position before gas supply is cut off in the absence of gas supply. Valves come in two types: those that open when there is gas supply and those that close; the difference lies in whether they open or close depending on the gas supply status, and the appropriate type should be selected based on specific requirements
From the picture, only the air filter pressure reducing valve and solenoid valve are visible; could you take another photo of the air circuit from the side?
Is there control air behind the solenoid valve?
Stop making noise upstairs; be serious. What the heck is a wind line? That’s called an air supply pipeline. Closing and releasing are not the same. First of all, when you close something, you’re simply turning off the air supply valve; in that case, the pressure inside the cylinder remains unchanged, and of course the valve won’t move. Try turning off the air supply valve and then disconnecting the air supply tube at the back – you’ll see gas spraying out, and the valve will close as well.
Yes, using professional terminology is the universal language.
We usually also call it the wind line. . . . It seems we’re not very professional either. . . Strive to improve! ! !
According to the description, this valve is an air-operated valve; it will close when the air supply is cut off or the valve controlling the air line is closed. Once the air line is connected and the air supply valve is opened, switch the internal control instruments to manual mode, and the output valve position should then allow the valve to open.
Is it dual-intake with dual safety mechanisms? Is it a dual-cylinder design? Is there a balance valve?…
