The utility model discloses a use method as follows:

when the water pressure is normal, water flow enters the connector 3 from the water inlet connector 2 through the spherical opening and closing piece 4, then the water flow sequentially passes through the first water through hole 9, the second water through hole 18, the third water through hole 19 and the inner hole of the limiting ring 12 and flows out of the water outlet connector 7 for use, the repulsive force between the left magnet plate 16 and the right magnet plate 13 is balanced with the water pressure, and the left magnet plate 16 and the limiting block 15 are kept in a mutually attached state.

When the water pressure is too high, the water pressure of the water flow is greater than the repulsive force between the left magnet plate 16 and the right magnet plate 13, when the water flow flows through the second through hole 24 on the left magnet plate 16, a part of the water flow impacts on the left side wall of the left magnet plate 16 and pushes the left magnet plate 16 rightwards, at the moment, the left magnet plate 16 moves rightwards along the track of the plastic rod 14 and gradually approaches the right magnet plate 13, because the right magnetic pole of the left magnet plate 16 and the left magnetic pole of the right magnet plate 13 repel each other, the smaller the distance between the two is, the larger the generated repulsive force is, the gradually-increased repulsive force can buffer the water flow impacting on the left magnet plate 16 through the left magnet plate 16, a part of the water pressure is eliminated, and the pressure reduction effect is effectively achieved.

When the repulsion force that increases gradually between left magnet board 16 and right magnet board 13 still can't make rivers water pressure resume normal often, under the high pressure effect, some rivers then can directly enter into auxiliary hole 22 through perforation 24 when the plastic sheath 11 flows through, and be full of a plurality of elastic balls 23 in the auxiliary hole 22, along with follow-up rivers constantly rush into auxiliary hole 22, the rivers that get into in the auxiliary hole 22 then can extrude elastic balls 23, elastic balls 23 then can produce elasticity and further cushion rivers water pressure this moment, further reduce water pressure.

In conclusion, the utility model discloses can know, the utility model discloses repulsion force and the supplementary pressure relief device between 16 and the right magnet board 13 of accessible left side magnet board can form the multichannel buffering, when rivers water pressure is too big, the very first time is automatic to water pressure buffering step-down, make originally too high water pressure resume to normal water pressure, effectively avoid too high water pressure to strike the condition that leads to becoming flexible leaking to the position of being connected between water connectors 7 and the pipeline, effectively avoid too high water pressure to strike the condition that leads to the inside part to damage to 1 inside part of valve body.
