Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] Please refer to Figures 1-5 , the present utility model provides a technical solution: a diaphragm pad for a liquid feeding valve, including an outer layer 1, a second interlayer 2 is connected below the outer layer 1, a third interlayer 3 is connected below the second interlayer 2, an inner layer 4 is connected below the third interlayer 3, four fixed sleeves 5 are penetrated and arranged in the outer layer 1, an elastic layer 6 is connected to the outer layer 1, a cross-shaped reinforcing rib 7 is arranged in the elastic layer 6, four protective pads 8 are connected in the elastic layer 6, a pull-back spring 9 is connected in the protective pad 8, and a sealing pad 10 is connected below the inner layer 4.

[0033] By arranging the cross-shaped reinforcing ribs 7, the service life of the product is enhanced; it can withstand high temperature, high pressure and strong impact under high-frequency use, and the special design ensures the sealing performance.

[0034] Specifically, as Figures 1-3 shown, the fixed sleeve 5 is penetrated and connected in the inner layer 4, the protective pad 8 is connected outside the cross-shaped reinforcing rib 7, the pull-back spring 9 is connected in the elastic layer 6, and the sealing pad 10 corresponds to the position of the elastic layer 6.

[0035] By setting the pull-back spring 9, after the protective pad 8 is squeezed, the pull-back spring 9 exerts an elastic force on the protective pad 8 at this time. The elastic force drives the protective pad 8 to move, so that it can be quickly reset. When the material does not flow, the pull-back spring 9 exerts an elastic force on the protective pad 8 at this time to keep it stable.

[0036] Specifically, as Figures 3-5 shown, the outer layer 1 is polyurethane, the second interlayer 2 is polytetrafluoroethylene, the third interlayer 3 is silicone rubber, and the inner layer 4 is ethylene propylene diene monomer rubber.

[0037] By setting the outer layer 1, the second interlayer 2, the third interlayer 3, and the inner layer 4 as a diaphragm pad with a multi-layer composite structure of a polyurethane layer, a polytetrafluoroethylene layer, a silicone rubber layer, and an ethylene propylene diene monomer rubber layer respectively, it not only provides excellent wear resistance, chemical inertness, and heat resistance, but also ensures the safety and hygiene of the contact surface with the feed. The design of this multi-layer material effectively improves the overall performance and durability of the diaphragm pad.

[0038] Working principle, when in use: The diaphragm pad with a multi-layer composite structure of a polyurethane layer, a polytetrafluoroethylene layer, a silicone rubber layer, and an ethylene propylene diene monomer rubber layer not only provides excellent wear resistance, chemical inertness, and heat resistance, but also ensures the safety and hygiene of the contact surface with the feed. The design of this multi-layer material effectively improves the overall performance and durability of the diaphragm pad. In addition, the enhanced design of the cross-shaped reinforcing ribs 7 greatly improves the service life of the product. When the liquid material passes through, the material exerts a thrust on the protective pad 8 at this time. The thrust drives the protective pad 8 to move. The protective pad 8 exerts a squeezing force on the pull-back spring 9. The squeezing force drives the pull-back spring 9 to compress. Subsequently, the pull-back spring 9 exerts an elastic force on the protective pad 8. The elastic force drives the protective pad 8 to be quickly reset. Thus, the quality can be guaranteed when in use.

[0039] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
