[0024] The specific embodiments of the present application will be described in detail below with reference to the drawings.
[0025] AsFigures 1 to 4 As shown in the figure, a flat plate limiting type valve plate 1 assembly, the assembly includes valve plate 1, valve piece 2, flat plate limiting block 3 and screw 4. Among them, the valve piece 2 (using Swiss imported 7C material) and the flat plate limiting block 3 (using peek material) are sequentially arranged from bottom to top in the middle of the top surface of the valve plate 1, and are connected and fixed by the screw 4.
[0026] As shown in Figure 1 , Figure 2 and Figure 4 , the bottom surface of the flat plate limiting block 3 is provided with a lifting column 6 for ensuring the up-down movement of the valve piece 2. The lifting column 6 and the screw 4 are each provided with four groups, and the four groups of lifting columns 6 are respectively located on the four corners of the flat plate limiting block 3, and the four groups of screws 4 are respectively threaded through the four groups of lifting columns 6.
[0027] By providing the lifting column 6, it is ensured that the valve piece 2 can move up and down well during subsequent work, and the height of the lifting column 6 is 8-12mm. Four screws 4 are used to fix the valve piece 2 and the flat plate limiting block 3 to the valve plate 1, so that the valve piece 2 is always straight downward, and will not be tilted due to installation problems, and the valve piece 2 has a free and straight upward and downward movement space, and will not be deformed due to strong medium impact.
[0028] Among them, the valve piece 2 is provided with a through hole, in order to facilitate the screw 4 to directly pass through, and to ensure that the flat plate limiting block 3 and the screw 4 will not be deformed during installation.
