[0041] Working principle: when in use, first, in the initial state, the low-pressure chambers and the booster chambers in the system have water left over from the last shutdown. The T port is connected to a water storage bottle, and there is no pressure. The reversing valve 1 works in the state shown in FIG. 1. Figure 18As shown in the valve position, after the system is powered on, pressurized water flows in from port P, passes through port A of the reversing valve, and enters low-pressure chamber A. Low-pressure chamber A is located above the large piston 4021. At this time, other pipelines are pressureless. The large piston 4021 is pushed by the pressurized water, driving the small piston 4022. Since the large piston 4021 has a larger area and the small piston 4022 has a smaller area, according to the principle of force balance, the output pressure of the booster chamber B located below the small piston 4022 is greater than the inlet water pressure, which is the area of ​​the large piston 4021 ÷ the area of ​​the small piston 4022 × the inlet water pressure. At this time, the low-pressure chamber B located below the large piston 4021 and the booster chamber A located above the small piston 4022 are approximately pressureless. When the large piston 4021 moves to the position represented by the dotted line, the pressurized water passes through the water path represented by the dotted line and pushes the reversing valve 1 to switch directions. The reversing valve 1 operates as follows: Figure 19 The waterway is shown, and then, according to Figure 19 As shown, pressurized water enters the low-pressure chamber B, located below the large piston 4021, from port P. High-pressure water is output from the booster chamber A, located above the small piston 4022. This high-pressure water, through the water path shown by the dotted line, pushes the reversing valve 1 to maintain its position until the small piston 4022 moves to... Figure 19 At the middle dashed line, Figure 19 The water circuits at the upper and lower dotted lines have no pressure, the steel ball 4032 in the one-way valve assembly 403 resets, and the directional valve 1 operates in... Figure 19 The valve position shown is used in this cycle to ensure that the outlet pressure (OUT) is higher than the inlet pressure. Finally, for locations where wiring is convenient, Figure 18 and Figure 19 The dotted line in the diagram controls the water path, which can be connected to an electromagnetic coil to provide thrust for the reversing valve 1 during reversal.
