[0002] The compressor valve is an important component in the compressor used to control the timely intake and discharge of gas into and out of the cylinder.

[0003] The spring in the air valve enables it to open and close automatically. However, when used with large air intake, the existing device only has a one-way buffer support effect, which leads to poor buffering effect when facing high pressure and inability to reset the seal in time. In addition, the existing device generally uses a single buffer spring, which easily leads to large limitations on its support performance and is unable to provide corresponding buffer support for large air intake, affecting the stability and accuracy of the device when used.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0026] Example 1: A multi-buffer structure air valve suitable for large air intake compressors, such as Figure 1-Figure 5 As shown, it includes a supporting valve seat 1 and a bottom supporting cylinder 3 installed on the lower end surface of the supporting valve seat 1. A plurality of flow holes 2 are provided through the upper end of the supporting valve seat 1, and a plurality of connecting grooves 4 are opened inside the bottom supporting cylinder 3. A sealing valve head 5 for sealing and supporting the flow holes 2 is provided inside the connecting groove 4. A guide column 6 is installed at the lower end of the sealing valve head 5, and a vertical spring 7 is installed at the lower end of the guide column 6. An extrusion cone 8 is installed on the upper half of the outer side of the guide column 6, and two symmetrically distributed arc-shaped guide cones 9 are provided on the outer side of the extrusion cone 8. At least two connecting rods 10 are installed on the end of the arc-shaped guide cone 9 away from the extrusion cone 8, and a transverse spring 11 is installed on the end of the connecting rod 10 away from the arc-shaped guide cone 9.

[0027] When the device is in use, the air flow flows through the flow hole 2 to the inside of the support valve seat 1. When the air flow pressure gradually increases, the sealing valve head 5 is pressed downward, causing the guide column 6 and the extrusion cone 8 to move downward at the same time. As the extrusion cone 8 gradually contacts the arc-shaped guide cone 9, based on the guidance of the connecting rod 10, the lateral springs 11 on both sides are compressed. At the same time, under the guidance of the guide column 6, the vertical spring 7 is compressed. With the combined use of the vertical spring 7 below and the lateral springs 11 on both sides, as well as the elastic support of the vertical spring 7 and the lateral spring 11 themselves, buffer support is provided for the device from both the horizontal and vertical directions, thereby improving the stability of the elastic support of the device when used with large air intake, and effectively preventing the device from being unable to automatically reset the support in time due to excessive air intake.

[0028] like Figure 1-Figure 5 As shown, the side of the arc-shaped guide cone 9 adjacent to the extrusion cone 8 presents a conical structure adapted to the outer side of the extrusion cone 8, and one extrusion cone 8 and two arc-shaped guide cones 9 operate as a group.

[0029] With the support of the conical surfaces of the arc-shaped guide cones 9 on both sides, the extrusion cone 8 gradually contacts the arc-shaped guide cone 9, and the transverse spring 11 on one side of the arc-shaped guide cone 9 is gradually compressed, providing gradually increasing buffer support for the downward movement of the sealing valve head 5 above the extrusion cone 8, ensuring that when the air intake of the device increases, its support performance will automatically and gradually improve, ensuring the stability and efficiency of the device during use.

[0030] like Figure 1-Figure 5 As shown, the arc-shaped guide cone 9 is slidably arranged on the inner wall of the connecting groove 4 through the guide rod 12. The inner wall of the connecting groove 4 is provided with two symmetrically distributed support grooves, the transverse spring 11 is installed inside the support groove, and the connecting rod 10 is slidably installed inside the support groove.

[0031] Under the guidance and support of the supporting groove inside the connecting groove 4, the accuracy of the angle of the transverse spring 11 during elastic operation and the sliding of the connecting rod 10 is ensured, and with the guidance assistance of the guide rod 12, its stability and efficiency during use are further guaranteed. At the same time, based on the contact limit of the arc-shaped guide cone 9 and the extrusion cone 8, the distance between the connecting rod 10 and the transverse spring 11 during expansion is guaranteed to be stable, thereby improving the safety and stability of the use of the transverse spring 11.

[0032] Example 2: A multi-buffer structure air valve suitable for large air intake compressors, such as Figure 1-Figure 5 As shown, at least two connecting holes 13 are opened inside the connecting groove 4, and the connecting holes 13 pass through to the lower end of the bottom support tube 3.

[0033] The circulation hole 2, the communication groove 4 and the connection hole 13 are internally communicated.

[0034] A flow space is formed between the support valve seat 1 and adjacent two sides of the bottom support cylinder 3 , and the sealing valve head 5 is located inside the flow space.

[0035] With the mutual connection support of the circulation hole 2, the connecting groove 4, and the connecting hole 13, the stability and accuracy of the device when used to support the airflow are guaranteed. At the same time, with the limiting support of the supporting valve seat 1 and the bottom supporting tube 3, the moving distance of the sealing valve head 5 is guaranteed to be stable and reliable, thereby improving the stability and accuracy of its sealing of the circulation hole 2.

[0036] like Figure 1-Figure 5 As shown, the support valve seat 1 and the bottom support tube 3 are both threadedly connected with a fastening bolt 14, and the fastening bolt 14 extends from the upper end of the support valve seat 1 and the lower end of the bottom support tube 3, and nuts are threadedly connected at both opposite ends of the fastening bolt 14.

[0037] Under the connection of the fastening bolt 14, the stability between the supporting valve seat 1 and the bottom supporting cylinder 3 when connected for use is further guaranteed, thereby ensuring the reliability and stability of the device when in use.

[0038] Working principle: When the device is used in the face of a large air intake, the airflow flows through the flow hole 2 to the inside of the support valve seat 1, causing the sealing valve head 5 to be pressed down, causing the guide column 6 and the extrusion cone 8 to move downward at the same time, causing the transverse springs 11 on both sides to be compressed, and the vertical spring 7 to be compressed. Under the combined use of the vertical spring 7 below and the transverse springs 11 on both sides, as well as the elastic support of the vertical spring 7 and the transverse spring 11 themselves, buffer support is provided for the device from both the transverse and longitudinal directions, thereby improving the stability of the elastic support of the device when used in the face of a large air intake.

[0039] 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.
