Problem of multiple paths along a route and mutual influence of traffic flows
Thread Content
Now, it is necessary to divide a single stream of PCW water into multiple streams, with the flow rate of each stream being adjustable independently without affecting one another. How should this system be designed to achieve this?
A set of automatic adjustment system can be installed for each circuit to achieve this.
As long as the pressure in front is high, especially when the pressure at the back is low enough, controlling the shunt should be quite simple.
How exactly should it be controlled? Could you introduce it?
Currently, only two of these channels require automatic adjustment, while the other 6 channels need to be adjusted manually. If that’s the case, how should it be solved?
If that’s the case, then there are obviously no problems with automatic adjustment; for manual adjustment, it relies on humans to open and close the valves. However, it is possible to consider first maintaining a constant total pressure in order to reduce the impact of pressure fluctuations on branch adjustment, which also makes manual adjustment easier.
1. If the fluctuation in total pressure is small, is it feasible to use throttle valves to regulate the flow rate in each branch now? Additionally, the current total water supply pressure is 4 Bar; are there any throttle valves that can operate at pressures lower than this value? 2. If check valves are installed at the branching points of each branch as well as at the turn points (that is, by connecting the check valves in parallel with each branch), can this achieve stabilization of the pressure difference in the main pipe?
Throttle valve? I haven’t used it, so I’m not entirely sure, but to achieve stable manual adjustment, it is first necessary to ensure stability at the front end, with minimal fluctuations in load.
The problem now is that the traffic regulation in the other channels affects each other; how can this issue be resolved?
For the two circuits with strict requirements, control valves can be added; for the remaining manual valves, leave a margin to account for pressure drop.
If the adjustments affect each other, it indicates that the total pressure is insufficient, and a constant pressure cannot be maintained...
