[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. Through the arrangement of the convex plate and the arc-shaped plate, when the fluid rushes towards the butterfly valve plate, the arc-shaped plate will shunt the fluid, reducing the impact force of the fluid rushing towards the butterfly valve plate. At the same time, since the convex plate is an outwardly convex arc-shaped mechanism, the convex plate will disperse the impact force of the fluid, thereby greatly reducing the impact force of the fluid on the butterfly valve plate and improving the service life of the butterfly valve plate.

[0014] 2. Through the arrangement of the back support assembly, the back support assembly will support the butterfly valve plate and also strengthen the butterfly valve plate, thereby improving the impact resistance of the butterfly valve plate and further improving the service life of the butterfly valve plate.

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Refer to Figures 1-3A valve accessory with improved structure comprises a butterfly valve plate 5, a convex plate 1 is welded on one side of the butterfly valve plate 5, a back support assembly 6 for strengthening the butterfly valve plate 5 is arranged on the side of the butterfly valve plate 5 away from the convex plate 1, a plurality of fixing plates 3 are welded on one side of the convex plate 1, an arc plate 4 for diverting the fluid is welded between two fixing plates 3 opposed to each other up and down, a sealing ring 2 is bonded on the outer side of the butterfly valve plate 5, the thickness of the sealing ring 2 is greater than the thickness of the butterfly valve plate 5, so that the convex plate 1 and the back support assembly 6 are both located in the sealing ring 2, when the fluid rushes to the butterfly valve plate 5, the arc plate 4 will divert the fluid, and the convex plate 1 will disperse the impact force of the fluid, thereby greatly reducing the impact force of the fluid on the butterfly valve plate 5, and improving the service life of the butterfly valve plate 5.

[0021] In the utility model, the back support assembly 6 includes a fixing ring 11, the fixing ring 11 is welded on the side of the butterfly valve plate 5 away from the convex plate 1, the fixing ring 11 is welded with a concave plate 10, and the fixing ring 11 is welded with a plurality of first reinforcing ribs 8 and second reinforcing ribs 9 for reinforcing the fixing ring 11 and the concave plate 10.
