A groove is provided on the inner wall of the sealing collar 29, and a second spring 210 is fixedly connected inside the groove. The slider 211 is inserted inside the groove, and the top of the slider 211 is fixedly connected to one end of the second spring 210. By providing the second spring 210, when there is no flatulence inside the tank body 1, the second spring 210 can support the movable plate 24 is located at the bottom of the sealing ring 29; the top of the movable plate 24 is fixedly connected to a connecting rod 28, and the top of the connecting rod 28 is fixedly connected to a sealing cover plate 212, which is located inside the sealing ring 29, and the outer wall of the sealing cover plate 212 is provided with a sealing ring 23, and the sealing ring 23 is arranged between the sealing ring 29 and the sealing cover plate 212; this structure can ensure the sealing between the sealing ring 29 and the sealing cover plate 212 by arranging the sealing ring 23; the material of the breathable membrane 22 is a waterproof breathable membrane, and the breathable membrane 22 is located on the inner side of the baffle 27; this structure can ensure the smooth expansion of the tank body 1 by arranging the breathable membrane 22 The movable plate 24 is provided with a sealing cover plate 212 on the top, the sealing cover plate 212 and the movable plate 24 form a parallel structure, and the sealing cover plate 212 and the sealing collar 29 form a sliding connection; this structure can seal the top opening of the tank body 1 when there is no flatulence in the tank body 1 by setting the sealing cover plate 212; a through hole is provided on the outer wall of the cover body 21, a breathable membrane 22 is provided on one side of the through hole, and a baffle 27 is rotatably connected to the other side of the through hole; the device can automatically discharge the flatulence in the tank body 1, thereby improving the safety of using the tank body 1.

[0026] Working principle: When the liquid fertilizer dedicated static storage tank is used, when the tank body 1 is flatulent, the pressure inside the tank body 1 increases. Under the action of the pressure, the gas pushes the movable plate 24, so that the movable plate 24 slides upward inside the sealing ring 29 through the sliders 211 on both sides. During the sliding process, the movable plate 24 drives the sealing cover plate 212 to slide at the same time. During the sliding process, the slider 211 pushes the second spring 210 to slowly compress. When the sealing cover plate 212 separates from the sealing ring 29 during the sliding process, the gas is concentrated on the movable plate 24. The gas at 24 flows to both sides and is discharged from the exhaust hole of the slider 211, and then enters the cover body 21 from the gap between the sealing cover plate 212 and the sealing ring 29. Then the gas passes through the breathable membrane 22 to push the baffle 27, so that the baffle 27 rotates and opens, so that the gas can be discharged smoothly. When there is less inflation inside the tank body 1, the slider 211 and the movable plate 24 are located at the bottom of the sealing ring 29 under the support of the second spring 210. At this time, the sealing cover plate 212 seals the top of the sealing ring 29 without affecting the sealing effect of the tank body 1.
