The embodiment is as follows: referring to fig. 1-3, the clean biological diaphragm valve includes a clamp type valve seat 1, a diaphragm sheet 3 is disposed inside the clamp type valve seat 1, and a valve seat support 5 is mounted at the top end of the clamp type valve seat 1;

four cover-shaped nuts 14 are arranged at the top end of the valve seat support 5, spring washers 15 are arranged below the cover-shaped nuts 14, four second screws 16 are arranged below the clamp-type valve seat 1, and the top ends of the outer walls of the second screws 16 are in threaded fit with the cover-shaped nuts 14;

a stainless steel hand wheel 9 is rotatably arranged at the top end of the outer wall of the valve seat bracket 5, and a screw rod 6 is arranged on the inner wall of the stainless steel hand wheel 9;

a gland 11 is arranged at the top end of the stainless steel hand wheel 9, a first screw 10 penetrates through the gland 11, and the bottom end of the outer wall of the first screw 10 is in threaded fit with the inner wall of the top end of the screw rod 6;

the top end of the first screw 10 is provided with a groove, and the shape of the groove is of an inner hexagonal shape;

specifically, as shown in fig. 1 and 2, the screw 6 can be rotated by rotating the stainless steel hand wheel 9, so that the screw 6 is fed in the vertical direction by the cooperation of the screw 6 and the valve seat support 5.

The bottom end of the limiting ring 8 is provided with a wear-resistant pad 12, the outer walls of the limiting ring 8 and the wear-resistant pad 12 are provided with a valve clack 4, the inner wall of the valve clack 4 is fixed with a connecting screw 13, the top end of the outer wall of the diaphragm 3 is in threaded fit with the inner wall of the connecting screw 13, and a buffer cushion 2 is arranged between the diaphragm 3 and one end of the valve clack 4;
