DETAILED DESCRIPTION

[0048] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0049] like Figure 1-Figure 9 As shown, the compressor valve plate structure based on the 3D simulation model provided in this embodiment includes a compressor valve plate 1, an exhaust groove 101 is provided on one side of the compressor valve plate 1, an exhaust port 2 is provided inside the exhaust groove 101, a rubber sleeve 9 is fixedly arranged inside the exhaust port 2, an intake groove 102 is provided on the other side of the compressor valve plate 1, an intake port 3 is provided inside the intake groove 102, an exhaust groove 101 is provided at the port of the exhaust port 2, an intake groove 102 is provided at the port of the intake port 3, and the valve port shape of the air valve is reasonably designed. This design can significantly reduce the impact sound between the valve plate and the valve seat when the compressor is working, and a rubber sleeve 9 is used as a connecting material between the valve plate and the valve seat to reduce metal The exhaust valve plate 6 is fixedly arranged inside the exhaust sink 101, and the exhaust valve plate 6 is connected to the exhaust valve plate limiting plate 5 by the third fixing bolt 11. The exhaust valve plate limiting plate 5 is rotatably provided with a damping adjustment pin 7. The bottom of the damping adjustment pin 7 is against the upper side of the exhaust valve plate 6. The exhaust valve plate limiting plate 5 and the exhaust valve plate 6 are fixedly connected, and the exhaust valve plate limiting plate 5 has a certain limiting effect on the exhaust valve plate 6 to prevent the exhaust valve plate 6 from vibrating too much, thereby reducing the noise generated by the compressor valve plate 1. In addition, when the exhaust valve plate 6 vibrates, the vibration amplitude of the exhaust valve plate 6 can be adjusted by the damping adjustment pin 7, specifically:

[0050] The damping adjustment pin 7 includes an adjustment cylinder 701 and a spring 702 fixedly arranged at one end of the adjustment cylinder 701, and a rubber pad 703 is fixedly arranged on the spring 702. The rubber pad 703 abuts against the upper side of the exhaust valve plate 6, and the lower side of the exhaust valve plate 6 abuts against the rubber sleeve 9. The exhaust valve plate 6 is used to seal the exhaust port 2. Under the action of the upper spring 702, the exhaust valve plate 6 is squeezed to increase the strength of the exhaust valve plate 6 during the vibration process. By adjusting the adjustment cylinder 701 on the damping adjustment pin 7, the force on the exhaust valve plate 6 can be increased. The structure is simple and the adjustment is convenient and quick. The damping adjustment pin 7 is added to reduce vibration noise. This design can significantly reduce the impact sound between the valve plate and the valve seat when the compressor is working. The upper side of the exhaust valve plate 6 abuts against the rubber pad 703, and the lower side of the exhaust valve plate 6 abuts against the rubber sleeve 9.

At the same time, an air intake valve plate mechanism 8 is fixedly arranged inside the air intake port 3. The air intake valve plate limiting plate 802 limits the air intake valve plate 801 to prevent the vibration amplitude of the air intake valve plate 801 from being too large, resulting in excessive loudness. During the vibration of the air intake valve plate 801, a number of even The rubber rod fixing holes 301 are evenly distributed, and the rubber rods 807 are fixedly arranged inside the rubber rod fixing holes 301. The rubber rods 807 are evenly distributed around the air inlet 3. The air intake valve sheet 801 and the rubber rods 807 inside the rubber rod fixing holes 301 are against each other, so it can be used to reduce the collision between metals, thereby achieving the purpose of reducing noise. In order to avoid air leakage, a rubber ring 808 is fixedly arranged on one side of the air intake valve sheet 801, and the rubber ring 808 corresponds to the rubber rod 807. The rubber ring 808 is fixedly arranged on the air intake valve sheet 801, and the rubber ring 808 corresponds to the rubber rod 807, so it can not only effectively reduce the noise generated by the collision between metals, but also play a certain sealing role;

The air intake valve plate 801 is fixed inside the air intake sink 102 by the first fixing bolt 803, and the air intake valve plate limiting plate 802 is fixedly arranged inside the air intake sink 102 by the second fixing bolt 804, so as to improve the stability of the air intake valve plate 801 and the air intake valve plate limiting plate 802;

[0055] A pad guide column 704 is fixedly connected to the rubber pad 703, and the pad guide column 704 passes through the interior of the adjusting cylinder 701. When the exhaust valve plate 6 squeezes the spring 702 on the damping adjusting pin 7, in order to prevent the rubber pad 703 from deviating, a pad guide column 704 is fixedly arranged on the rubber pad 703. When the pad guide column 704 is squeezed, it can slide inside the adjusting cylinder 701, which plays a certain guiding and supporting role, thereby improving the stability of the movement of the rubber pad 703. Adjustment grooves 705 are provided on the adjusting cylinder 701 and the pad guide column 704. The damping adjusting pin 7 is adjusted by adjusting the adjustment grooves 705 on the pad guide column 704, thereby improving the convenience of use.
