How solenoid valves control flow
Thread Content
As shown in the figure below, the valve opening is controlled in the file using pipes with different inner diameters along with solenoid valves. I would like to know how this control is achieved – are five pipes of different sizes connected, or something else? I have a basic understanding of the principle behind solenoid valves, but not a thorough one. I hope someone experienced can explain it in simple terms. Thank you very much!
Could some kind-hearted expert please explain this to me? I’m in a hurry{:2_33:}
What is this used for? Is it one tube or multiple tubes going into the container? I’m not quite sure. The solenoid valve has no degree of opening control – it is either fully open or fully closed. If the diameters of the inlet pipes differ, then multiple pipes are used to regulate the flow rate
To control the gas flow into the vacuum tank and facilitate subsequent experimental procedures, there should be a tube leading into the container. I just know that solenoid valves cannot control the degree of opening; I’m not aware of the method for using multiple pipes together. There is a pipe on each side of the valve – I wonder if it’s possible to achieve what’s desired in this situation
It is possible to control the valve opening with a solenoid valve, and pulse control can be used. It can also be controlled by multiple pipelines and multiple solenoid valves, not through pulse control; since the flow coefficients of each solenoid valve are different, precise control can be achieved
Proportional valve for single tube, digital valve for multiple tubes
Thank you; the engineering team has reconsidered the approach and now plans to use multiple pipelines along with multiple solenoid valves for control. By the way, I’d like to learn about pulse control; could you explain it in detail if you have time? {:1_90:}
Thank you. I have a question regarding digital valves – I haven’t worked with them in previous projects, and I was unable to find the manufacturer when I encountered them last time. Does it require a control system, and is the output signal digital?
