The outer diameter of the second pipe member 22 is 25mm, and the inner diameter is 20 mm; the water blocking piece 221 is arranged in the middle of the second pipe 22, the diameter of the first water through hole is 8mm, the number of the third water through holes 2211 is six, the water blocking pieces are arranged in an annular array, and the diameter of the third water through holes 2211 is 2 mm; the third pipe member 222 has an outer diameter of 10mm and an inner diameter of 8mm, and the fourth water passing holes 2221 have four diameters of 1 mm. The diameter of the water outlet hole of the pressure stabilizing tube 23 is 2mm, the diameter of the water inlet hole is 8mm, the outer diameter of the bulge is 13mm, and the length is 17 mm. The number of the second water passing holes 231 is four, and the second water passing holes are uniformly distributed along the circumferential direction of the side wall of the straight cylinder part and have a diameter of 1 mm. The spring has an inner diameter of 11mm and an outer diameter of 13 mm.

The working process of the water pressure regulator in the embodiment is as follows: in general, the pressure regulator is used under the condition that the water outlet hole of the pressure stabilizing tube 23 is placed upwards, when the water pressure is low, the pressure stabilizing tube 23 is not abutted against the second pipe fitting 222 under the action of the spring, water flow washes the pressure regulating ball 25, the pressure regulating ball 25 rolls up and down in the pressure stabilizing tube 23, and the water flow flows out from a gap between the pressure stabilizing tube 23 and the first pipe fitting 21, the four second water through holes 231 and the water outlet hole of the pressure stabilizing tube 23 and flows upwards; a part of the water flows into the third pipe member 222 and then into the second pipe member 22 from the four fourth water through holes 2221 and the end of the third pipe member 222 near the surge tank 23, and another part flows into the second pipe member 22 from the six third water through holes 2211.

When the water pressure is high, the impact force of water flow on the pressure regulating ball 25 is high, the pressure regulating ball 25 blocks the water outlet hole of the pressure stabilizing tube 23, and the water flow flows out from the gap between the pressure stabilizing tube 23 and the first pipe fitting 21 and the four second water through holes 231 and flows upwards; the surge tube 23 will abut against the third tube member 222 if the water pressure is high enough, thereby reducing the amount of water in the third tube member 222; when the water pressure is not high enough, the surge tank 23 does not abut against the third tube member 222. When the pressure stabilizing pipe 23 is not abutted against the third pipe member 222, a part of water flows into the third pipe member 222 from the four fourth water through holes 2221 and one end of the third pipe member 222 close to the pressure stabilizing pipe 23 and then flows into the second pipe member 22, and the other part of water flows into the second pipe member 22 from the six third water through holes 2211. When the pressure-maintaining pipe 23 abuts against the third pipe member 222 due to a large water pressure, a part of the water flows from the four fourth water through holes 2221 into the third pipe member 222 and then into the second pipe member 22, and another part of the water flows from the six third water through holes 2211 to the second pipe member 22.
