In order to ensure that the adjusting valve rod 62 is in sealing contact with the inner wall of the pressure reducing pipe 61 and has sufficient sealing performance, the water inlet sealing control ring 621 and the water outlet sealing control ring 622 are provided with elastic sealing rings 624 in the circumferential direction for sealing contact with the inner wall of the pressure reducing pipe 61.
