[0026] During the implementation process, the pressure regulating device is fixed to the pump body of the three-cylinder plunger pump. During the pressure regulation process, the distance between the hand wheel and the pressure regulating tube is adjusted by turning the hand wheel. The spring 6 has different compression elastic forces at different distances, thereby generating different pressures on the valve stem 3 to achieve the pressure regulation effect.
[0027] During the pressure regulation process, the generated backflow flows out from the water return through hole. If all water return is required, the hand wheel 5 is completely screwed out to achieve complete connection between the water return through hole and the pressure regulation through hole.

[0029] Preferably, the number of the sealing rings 20 is three.
[0030] Multiple sealing rings can improve the sealing effect and prevent problems such as water leakage in the gap when the valve stem slides in the pressure regulating pipe.
[0031] Preferably, a limiting protrusion 30 is formed on the top of the valve stem 3, and the bottom of the spring 6 is sleeved on the outer wall of the limiting protrusion 30, so as to facilitate the fixing of the bottom of the spring 6.
[0032] Preferably, the outer wall of the pressure regulating pipe 2 is formed with a limiting convex ring 21, and the lower end surface of the limiting convex ring 21 abuts against the upper end surface of the water return seat 1, so as to facilitate the installation of the pressure regulating pipe.
[0033] Preferably, the bottom of the valve stem 3 is formed with an upwardly extending vortex groove 31, and the valve ball 4 is embedded in the center of the vortex groove 31. In the above structure, the vortex groove 31 can conveniently fix the valve ball 4 to prevent deviation when sealing the top of the pressure regulating through hole.
