[0013] As a further solution of the present invention: a high-temperature resistant layer is fixedly connected to the surface of the first exhaust valve plate and the second exhaust valve plate, and the surface of the high-temperature resistant layer is plated with an anti-corrosion layer.

[0014] Compared with the prior art, the present invention provides a reciprocating compressor metal exhaust valve plate with multiple protection functions, which has the following beneficial effects:

[0025] Embodiment: A reciprocating compressor metal exhaust valve plate with multiple protection functions, such as Figure 1 - Figure 4 As shown, it includes a rotating mechanism, which includes a first exhaust valve disc 1, a second exhaust valve disc 2 and a rotating rod 8. The second exhaust valve disc 2 is located inside the first exhaust valve disc 1, and the rotating rod 8 passes through the first exhaust valve disc 1 and the second exhaust valve disc 2. The first exhaust valve disc 1 is rotatably connected to the rotating rod 8, and the second exhaust valve disc 2 is fixedly connected to the rotating rod 8. By arranging that the second exhaust valve disc 2 is located inside the first exhaust valve disc 1, and the rotating rod 8 passes through the first exhaust valve disc 1 and the second exhaust valve disc 2, when the staff rotates the rotating rod 8, the second exhaust valve disc 2 is driven to rotate together, thereby The dust and particles attached to the second exhaust valve disc 2 are rotated and shaken off. By providing an elastic device on the rotating rod 8, when the staff rotates the rotating rod 8 and lets go, the rotating rod 8 is quickly reset by the elastic device. Multiple operations allow the rotating rod 8 to shake off the dust particles attached to the first exhaust valve disc 1, thereby ensuring that the dust and particles attached to the first exhaust valve disc 1 and the second exhaust valve disc 2 are cleaned, avoiding dust particles from clogging the first exhaust valve disc 1 and the second exhaust valve disc 2, resulting in a reduction in their service life.

[0026] like Figure 1 - Figure 4As shown, at least two connecting rods 9 are rotatably connected to the rotating rod 8, and the first exhaust valve plate 1 is rotatably connected to the rotating rod 8 through the connecting rod 9. The rotating rod 8 is provided with two return springs 10, and the two ends of the return spring 10 are fixedly connected to the inner wall of the rotating rod 8 and one side of the connecting rod 9 respectively. By arranging two return springs 10 on the rotating rod 8, and the two ends of the return spring 10 are fixedly connected to the inner wall of the rotating rod 8 and one side of the connecting rod 9 respectively, the first exhaust valve plate 1 is fixedly connected to the connecting rod 9, and the rotating rod 8 is rotatably connected to the connecting rod 9, so that when the staff rotates the rotating rod 8, the return spring 10 inside it is driven to rotate, so that when the staff releases the rotating rotating rod 8, the return spring 10 drives the rotating rod 8 to quickly reset. Multiple operations allow the rotating rod 8 to shake off the dust particles attached to the first exhaust valve plate 1, thereby ensuring that the dust and particles attached to the first exhaust valve plate 1 are cleaned.

[0027] like Figure 1 - Figure 4 As shown, the diameter of the second exhaust valve disc 2 is slightly smaller than that of the first exhaust valve disc 1, and the second exhaust valve disc 2 is in contact with the first exhaust valve disc 1. The first exhaust valve disc 1 and the second exhaust valve disc 2 are both provided with a first annular groove 4, a second annular groove 5, a third annular groove 6 and a fourth annular groove 7 for air to pass through. By providing the first exhaust valve disc 1 and the second exhaust valve disc 2 with the first annular groove 4, the second annular groove 5, the third annular groove 6 and the fourth annular groove 7 for air circulation, the air can circulate more quickly during use.

[0028] like Figure 1 - Figure 4 As shown, the first annular groove 4, the second annular groove 5, the third annular groove 6 and the fourth annular groove 7 are arranged from the center outward on the first exhaust valve disc 1 and the second exhaust valve disc 2. The surfaces of the first exhaust valve disc 1 and the second exhaust valve disc 2 are fixedly connected with a high-temperature resistant layer 11, and the surface of the high-temperature resistant layer 11 is plated with an anti-corrosion layer 12. At the same time, the surfaces of the first exhaust valve disc 1 and the second exhaust valve disc 2 are fixedly connected with a high-temperature resistant layer 11, and the surface of the high-temperature resistant layer 11 is plated with an anti-corrosion layer 12. At the same time, the material of the high-temperature resistant layer 11 is composed of ordinary pure zinc plating. The high-temperature resistant layer 11 can improve the high-temperature tolerance of the first exhaust valve disc 1 and the second exhaust valve disc 2, and the corrosion-resistant layer 12 is composed of aluminum powder, which can effectively prevent the corrosive substances carried in the gas from corroding the first exhaust valve disc 1 and the second exhaust valve disc 2.

[0029] Working principle: The staff rotates the rotating rod 8, driving the second exhaust valve disc 2 to rotate together, and then the dust and particulate matter attached to the second exhaust valve disc 2 are rotated and shaken off. When the staff releases the rotating rotating rod 8, the reset spring 10 drives the rotating rod 8 to quickly reset. Multiple operations enable the rotating rod 8 to shake off the dust particles attached to the first exhaust valve disc 1, thereby ensuring that the dust and particulate matter attached to the first exhaust valve disc 1 and the second exhaust valve disc 2 are cleaned.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
