Abstract
Description
Technical Field
[0001] This application relates to the field of compressor technology, and in particular to a limiter for a compressor. Background Technology
[0002] During compressor operation, the exhaust valve plate performs a high-frequency snapping motion driven by high-pressure airflow. To constrain the maximum lift of the exhaust valve plate and prevent breakage, a fixed limiter is usually installed on the outside of the exhaust valve plate.
[0003] The rigid passive constraint mechanism of the limiter means that the exhaust valve plate will directly and rigidly collide with the limiter every time it opens. This continuous rigid collision is not only a major source of noise, but the impact stress it generates also affects the long-term service life of the exhaust valve plate. Utility Model Content
[0004] In order to reduce the noise generated by the exhaust valve plate and improve the service life of the exhaust valve plate, this application provides a limiter for a compressor.
[0005] The limiter for a compressor provided in this application adopts the following technical solution:
[0006] A limiter for a compressor includes a limit plate disposed in a valve plate mounting groove. The surface of the limit plate protrudes along its own length to form a limit platform. One end of the limit platform in the length direction protrudes to form a boss. The boss presses against one end of an exhaust valve plate. The limit platform gradually tilts in an arc shape away from the boss and away from the exhaust valve plate. An elastic buffer is disposed on the limit platform.
[0007] By adopting the above technical solution, when the exhaust valve plate opens, it impacts the elastic buffer of the limiting platform. The elastic buffer buffer cushions the impact of the exhaust valve plate, reducing the impact force of the exhaust valve plate on the limiter, thereby reducing the noise generated by the exhaust valve plate and improving the service life of the exhaust valve plate.
[0008] Preferably, the elastic buffer includes an elastic buffer ring and two elastic buffer strips. The elastic buffer ring is disposed on the side of the limiting platform surface away from the boss, and the two elastic buffer strips are disposed on the side of the limiting platform surface on the side of the elastic buffer ring close to the boss.
[0009] By adopting the above technical solution, when the exhaust valve plate is opened to the maximum angle, it impacts the elastic buffer ring and the elastic buffer strip. The elastic buffer ring buffers the far end of the exhaust valve plate, and the elastic buffer strip buffers the middle part of the exhaust valve plate, thereby making the elastic buffer component have a better buffering effect on the exhaust valve plate.
[0010] Preferably, the limiting platform includes a circular portion and a rectangular portion, the boss is disposed at one end of the rectangular portion along its length, the circular portion is located at the end of the rectangular portion away from the boss, the elastic buffer strip is disposed on the rectangular portion, the elastic buffer ring is disposed on the circular portion, and the diameter of the elastic buffer ring is greater than the distance between the two elastic buffer strips.
[0011] By adopting the above technical solution, when the exhaust valve plate is opened, the opening speed at its far end is the greatest, and the impact force when the far end opens is also the greatest. The circular part is used to support the elastic buffer ring, so that the diameter of the elastic buffer ring can be increased, thereby improving the buffering effect of the elastic buffer component on the far end of the exhaust valve plate.
[0012] Preferably, both the elastic buffer ring and the elastic buffer strip are detachably mounted on the limiting platform.
[0013] By adopting the above technical solution, the elastic buffer can be disassembled and replaced after long-term use, thereby ensuring the buffering effect of the elastic buffer.
[0014] Preferably, the elastic buffer ring is fixedly connected to two elastic buffer strips, and both the elastic buffer ring and the elastic buffer strips are embedded in the limiting platform. The end of the limiting platform away from the boss has a disassembly port for connecting with the elastic buffer ring.
[0015] By adopting the above technical solution, when it is necessary to disassemble the elastic buffer, a tool is inserted into the disassembly port to knock out the elastic buffer ring. The elastic buffer ring can then drive the two elastic buffer strips to fall off the limiting platform, thereby facilitating the quick disassembly of the elastic buffer.
[0016] Preferably, the height of the elastic buffer strip protruding from the limiting platform gradually increases from the platform toward the elastic buffer ring.
[0017] By adopting the above technical solution, the protrusion height of the elastic buffer strip towards the elastic buffer ring gradually increases, so that the end of the elastic buffer strip away from the elastic buffer ring will not interfere with the opening of the exhaust valve plate.
[0018] In summary, this application includes at least one of the following beneficial technical effects:
[0019] 1. By utilizing an elastic buffer, when the exhaust valve plate opens, it impacts the elastic buffer on the limit platform. The elastic buffer buffer cushions the impact of the exhaust valve plate, reducing the impact force of the exhaust valve plate on the limit device, thereby reducing the noise generated by the exhaust valve plate and improving the service life of the exhaust valve plate.
[0020] 2. With the help of elastic buffer rings and elastic buffer strips, when the exhaust valve plate is opened to the maximum angle, it impacts the elastic buffer rings and elastic buffer strips. The elastic buffer rings buffer the far end of the exhaust valve plate, and the elastic buffer strips buffer the middle part of the exhaust valve plate, thus making the elastic buffer components have a better buffering effect on the exhaust valve plate.
[0021] 3. When it is necessary to disassemble the elastic buffer component through the disassembly port, use a tool to insert into the disassembly port and knock out the elastic buffer ring. After the elastic buffer ring is knocked out, it can drive the two elastic buffer strips to fall off the limiting platform, thus facilitating the quick disassembly of the elastic buffer component.

[0025] The following is in conjunction with the appendix Figures 1-2 This application will be described in further detail.
[0026] This application discloses a limiter for a compressor.
[0027] Reference Figure 1 and Figure 2 A limiter for a compressor includes a limit plate 1. One end of the limit plate 1 along its length has a locking portion 6. The limit plate 1 is mounted in a mounting groove of a valve disc via the locking portion 6. A circular hole in the locking portion 6 is used to engage with a corresponding structure on the valve disc to improve the stability of the locking portion 6 during installation. A boss 3 protrudes from the end of the limit plate 1 along its length away from the locking portion 6, and the boss 3 presses against the proximal end of an exhaust valve plate 7.
[0028] The limiting plate 1 is bent into an arc shape from the boss 3 toward the snap-fit part 6 and gradually away from the exhaust valve piece 7. The limiting plate 1 has an arc-shaped limiting platform 2 protruding on its own arc surface. An elastic buffer 4 is detachably installed on the limiting platform 2.
[0029] The limiting platform 2 is composed of a circular portion 21 and a rectangular portion 22, the diameter of the circular portion 21 being larger than the width of the rectangular portion 22. The circular portion 21 is located on the side closer to the snap-fit portion 6, and the rectangular portion 22 is located on the side closer to the boss 3. The rectangular portion 22 is fixedly connected to the circular portion 21, and the boss 3 is located on the end of the rectangular portion 22 away from the circular portion 21.
[0030] The elastic buffer 4 consists of an elastic buffer ring 41 and two elastic buffer strips 42. The elastic buffer ring 41 is concentrically and detachably embedded in the circular portion 21, and the two elastic buffer strips 42 are detachably embedded in the rectangular portion 22. The elastic buffer strips 42 are installed along the length of the rectangular portion 22, and the two elastic buffer strips 42 are spaced apart along the width of the rectangular portion 22. The height of the elastic buffer strips 42 protruding from the rectangular portion 22 gradually increases from the boss 3 to the snap-fit portion 6, and the height of the end of the elastic buffer strip 42 away from the boss 3 is the same as the height of the elastic buffer ring 41.
[0031] The ends of the two elastic buffer strips 42 are fixedly connected to the elastic buffer ring 41, and the diameter of the elastic buffer ring 41 is larger than the distance between the two elastic buffer strips 42. In this application, both the elastic buffer strips 42 and the elastic buffer ring 41 can be made of rubber material. A disassembly port 5 is provided at the end of the circular portion 21 away from the rectangular portion 22, and the disassembly port 5 communicates with the insertion groove of the elastic buffer cavity on the circular portion 21.
[0032] The implementation principle of a limiter for a compressor according to an embodiment of this application is as follows: when the exhaust valve plate 7 reaches its maximum opening angle, the distal end of the exhaust valve plate 7 contacts the elastic buffer ring 41, and the middle part of the exhaust valve plate 7 contacts the elastic buffer strip 42, forming a buffer. The elastic buffer 4 can effectively absorb and mitigate the impact energy of the exhaust valve plate 7, thereby significantly suppressing noise and improving the service life of the exhaust valve plate 7. At the same time, during the disassembly process, by using a tool to act on the disassembly port 5, the elastic buffer ring 41 can be knocked out of the circular part 21, and at the same time, the elastic buffer ring 41 drives the two elastic buffer strips 42 to disengage from the rectangular part 22, realizing the efficient disassembly of the elastic buffer 4.
[0033] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
