(3) when the pressure is released, the coil 27 is energized to generate a magnetic field, the moving magnet 29 overcomes the elastic force of the thrust elastic element 292 under the action of the magnetic field to move the moving magnet 29 toward the direction away from the fluid pressure release end 23, the sealing valve core 291 is separated from the opening of the fluid pressure release end 23 to open the fluid pressure release end 233, at this time, the fluid in the storage element flows back into the fluid pressure release end 23 through the fluid discharge end 22, and is finally discharged to the outside from the fluid pressure release end 23, so that the pressure release of the storage element is realized.
