From the perspective of fluid mechanics, a pressure reducing valve is a throttling element with variable local resistance. That is, by changing the throttling area, the flow rate and the kinetic energy of the fluid are changed, resulting in different pressure losses, thereby achieving the purpose of pressure reduction.

At the same time, the stability of its pressure reducing control is limited, and it is also prone to leakage, affecting the safety and reliability of use. Therefore, its applicability and practicality are limited. Summary of the Invention

In this embodiment, the connecting pipe is a conventional structure of the prior art and is simply applied.

[0026] In actual use, the switch valve structure includes a valve body 21, a connecting channel 22 disposed in the middle of the side of the valve body, a control switch 23 disposed at the bottom of the valve body, and a pressure-stabilizing adjustment structure 24 disposed at the top of the valve body. During assembly, the pressure-stabilizing adjustment structure is located directly above the control switch. The pressure-stabilizing adjustment structure presses and changes the flow rate between the connecting channel and the control switch. Furthermore, in this embodiment, the pressure-stabilizing adjustment structure includes an adjustment seat 241, an adjustment head 242, a spring 243, and a regulating valve head 244.

The pressure-stabilizing regulating structure is mainly used to press and cooperate with the control switch to achieve flow regulation control. The pressure-stabilizing regulating structure is mainly connected and reset by a spring. When the regulating head is pressed downward, the regulating head will drive the regulating valve head downward and upward through the spring, thereby adjusting the size of the flow channel and cooperating with the control switch to achieve flow control.
