In this embodiment, the sealing plate 5 at the bottom end of the first elastic component 4 can allow liquid to enter the interior through one end of the high-toughness check valve body 1, and exert a certain pressure on the sealing plate 5, so that the first elastic component 4 is squeezed and contracted, and the sealing plate 5 moves upward, so that the liquid passes through the high-toughness check valve body 1 and is discharged from the other end. When the liquid returns, the sealing plate 5 exerts downward pressure, so that the sealing plate 5 blocks the interior of the high-toughness check valve body 1, so that the high-toughness check valve body 1 prevents the liquid from flowing back. When the circulation of liquids with different pressures is met, the adjusting shaft 7 on the rotating bearing seat 6 is driven by the adjusting shaft 7 to rotate the rectangular column 9 through the rectangular groove, and the rectangular column 9 drives the sealing block 3 to rotate. The sealing groove is threadedly connected to the sealing block 3, and the sealing block 3 rotates and moves in the sealing groove, thereby adjusting the distance between the sealing block 3 and the sealing plate 5, thereby adjusting the elastic support strength of the first elastic component 4, and realizing the adjustment of the downward pressure of the sealing plate 5.
