Fluid self-circulation system
By designing a self-regulating fluid circulation system with a check/stop and reversal device and a return conduit, the problem of low circulation efficiency of gaseous and liquid fluids is solved by utilizing the Brownian motion and gravitational potential energy of gaseous fluids. This achieves self-regulating circulation of gaseous fluids and continuous circulation of liquid fluids, thereby improving the system's resource utilization rate.

AI Technical Summary
In existing fluid circulation systems, the circulation efficiency of gaseous and liquid fluids is low, and it is difficult to effectively utilize the pressure of gaseous fluids for self-circulation, resulting in resource waste.
A self-regulating fluid circulation system was designed, which utilizes the Brownian motion and gravitational potential energy of the gaseous fluid. Through a check-and-go device and a return conduit, the gaseous fluid maintains its own pressure within the pressure chamber. The circulation of the liquid fluid is controlled by a return inlet and a switching valve, ensuring that the gaseous fluid does not flow backward and that the liquid fluid circulates smoothly.
It achieves long-term pressure maintenance of gaseous fluids within the pressure chamber and continuous circulation of liquid fluids, improving the efficiency and resource utilization of the fluid circulation system and reducing the possibility of backflow.
