[0009] In the above-mentioned air compressor valve plate, a first threaded hole is provided in the middle of the first groove, and a first bolt is fixed in the first threaded hole.

[0010] In the aforementioned air compressor valve plate, a second threaded hole is provided in the middle of the second groove, and a second bolt is fixed in the second threaded hole.

[0011] In the aforementioned air compressor valve plate, a cylinder connection groove is provided on the lower end face of the valve plate body.

[0012] Compared with the prior art, the air compressor valve plate provided by this utility model has the following advantages: 1. By opening a first connecting groove in the first groove and setting a pad connecting foot below the pad, the valve plate body and the pad are fixed together by the first connecting groove and the pad connecting foot. The pad fixes the outlet valve plate. This structure is stable and easy to install automatically, without the need for manual operation of fixing the pad with bolts; 2. By opening a second connecting groove in the second groove and setting a limiting piece, the intake valve plate can be fixed to the valve plate body. The limiting piece structure is stable and easy to install automatically. Attached Figure Description

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figures 1 to 5 As shown, this embodiment includes a valve plate body 1, a pad 2, an intake valve plate 3, and an exhaust valve plate 4. A first groove 11 is provided on the upper surface of the valve plate body 1. The first groove 11 is roughly annular and connected at both ends. An exhaust hole 13 is provided on the valve plate body 1 at the middle of the first groove 11. Two first connecting grooves 111 are provided inside the first groove 11. The first connecting grooves 111 are located in the middle of the first groove 11 and are symmetrically arranged. The depth of the first connecting grooves 111 is greater than the depth of the first groove 11. Two pad connecting feet 21 are integrally formed below the pad 2. The pad connecting feet 21 match the first connecting grooves 111 and can be fixedly connected. An exhaust valve plate 4 is fixedly installed below the pad 2. The exhaust valve plate 4 is located outside the exhaust hole 13. A first threaded hole 112 is provided in the middle of the first groove 11. A first bolt 6 is fixed in the first threaded hole 112. The first bolt 6 passes through the pad 2 and the exhaust valve plate 4 and connects and fixes the pad 2 and the exhaust valve plate 4 to the valve plate body 1.

[0021] like Figures 1 to 5 As shown, a second groove 12 is formed on the lower end face of the valve plate body 1. The second groove 12 has the same shape as the first groove 11. An air inlet 14 is formed in the inner ring of the second groove 12. Two second connecting grooves 121 are formed inside the second groove 12. The second connecting grooves 121 are located in the middle of the second groove 12 and are symmetrically arranged. The depth of the second connecting grooves 121 is greater than the depth of the second groove 12.
