Description

Technical Field

[0001] The present application relates to the technical field of compressors, and particularly relates to an exhaust valve assembly, a compressor and an air conditioner. Background Art

[0002] The exhaust assembly of a rotary compressor usually consists of a baffle plate, a valve plate, rivets, an exhaust valve seat, etc. Both the valve plate and the valve seat are made of metal materials. When the compressor is operating, after the high-pressure gas reaches the condensation pressure, it pushes open the valve plate through the exhaust port and discharges the gas outward. After the exhaust is completed, the valve plate swings downward quickly to close the exhaust port. At this time, the valve plate hitting the valve seat is likely to generate a large impact force, thus forming a large mechanical noise, resulting in the noise of the compressor exceeding the test standard and the sound quality being poor.

[0003] In the related art, an exhaust structure of a rotary compressor is disclosed. By providing a seat ring made of non-metallic material on the valve seat, the valve plate directly hits the seat ring for buffering and vibration reduction, and the seal between the seat ring and the valve plate changes from a rigid seal to a soft seal, with a better sealing effect, which can improve the service life of the valve plate and reduce the noise during the operation of the compressor. However, this exhaust structure only provides an annular seat ring on the valve seat around the exhaust port. When the valve plate hits the valve seat, the impact energy that the annular seat ring can consume is limited, so the vibration reduction effect is poor. Summary of the Invention

[0011] Preferably, an annular groove is provided on the periphery of the refrigerant flow hole of the exhaust valve gasket, and the damping ring is installed in the annular groove.

[0012] Preferably, the structural strength of the exhaust valve gasket is greater than that of the damping ring.

[0013] Preferably, a vibration damping groove is provided on the periphery of the refrigerant flow hole on the side of the exhaust valve gasket facing the valve plate, and a preset interval is provided between the vibration damping groove and the refrigerant flow hole.

[0014] Preferably, circumferentially extending holes and radially extending holes are provided on the periphery of the refrigerant flow hole of the exhaust valve gasket, and the circumferentially extending holes and the radially extending holes are arranged alternately and spaced along the circumferential direction.

[0018] According to another aspect of the present application, an air conditioner is provided, including an exhaust valve assembly, and the exhaust valve assembly is the above-mentioned exhaust valve assembly.

[0019] The exhaust valve assembly, flange and exhaust assembly provided by this application. The flange is provided with a valve seat, the valve seat is provided with an exhaust groove, the bottom of the exhaust groove is provided with an exhaust port, the exhaust assembly is arranged on the valve seat, the exhaust assembly includes a valve piece capable of closing the exhaust port, an exhaust valve gasket is arranged in the exhaust groove, the exhaust valve gasket is made of a damping material, the structure of the exhaust valve gasket is adapted to the exhaust groove, a refrigerant flow hole is arranged on the exhaust valve gasket corresponding to the exhaust port, and the height of the exhaust valve gasket is flush with or higher than the height of the installation surface where the valve piece is arranged.

[0037] Referring to Figures 1 to 15 As shown, according to the embodiment of the present application, the exhaust valve assembly includes a flange 1 and an exhaust assembly. The flange 1 is provided with a valve seat 2. The valve seat 2 is provided with an exhaust groove 6. The bottom of the exhaust groove 6 is provided with an exhaust port 3. The exhaust assembly is arranged on the valve seat 2. The exhaust assembly includes a valve plate 4 capable of closing the exhaust port 3. An exhaust valve gasket 7 is arranged in the exhaust groove 6. The exhaust valve gasket 7 is made of a damping material. The structure of the exhaust valve gasket 7 is adapted to the exhaust groove 6. A refrigerant flow hole 5 corresponding to the exhaust port 3 is arranged on the exhaust valve gasket 7. The height of the exhaust valve gasket 7 is flush with or higher than the height of the mounting surface where the valve plate 4 is arranged.

[0038] An exhaust valve assembly lays an exhaust valve gasket 7 in the exhaust groove 6 of the valve seat 2, so that the entire surface of the exhaust groove 6 of the valve seat 2 is covered by the exhaust valve gasket 7. During the process of the valve plate 4 slapping the valve seat 2, the valve plate 4 cannot directly slap on the surface of the exhaust groove 6 and will directly slap on the exhaust valve gasket 7. Since the exhaust valve gasket 7 is made of a damping material, the damping characteristics of the exhaust valve gasket 7 can be used to absorb the energy of the valve plate 4 slapping the valve seat 2. Since the exhaust valve gasket 7 covers the entire exhaust groove 6 and has a larger contact area with the valve plate 4, the valve plate 4 basically completely slaps on the exhaust valve gasket 7. Therefore, the exhaust valve gasket 7 has a stronger ability to absorb the energy of the valve plate 4 slapping the valve seat 2, can more effectively reduce the acting force of the valve plate 4 when closing and slapping the valve seat 2, reduce the impact of the valve plate 4 on the valve seat 2, effectively protect both the valve plate 4 and the valve seat 2, improve the service life of the valve plate 4 and the reliability of the compressor, and reduce the noise of the compressor.

[0039] In one embodiment, the exhaust valve gasket 7 can be made of flexible valve plate materials such as PA, POM, Mn-Cu alloy, etc., which can have a better vibration damping effect.

[0040] The exhaust valve assembly of this embodiment can be applied to various compressors and air compressors, with good applicability and a wide application range.

[0041] This exhaust valve assembly is particularly suitable for sliding vane compressors and can also be applied to rotary compressors and scroll compressors.

[0042] In one embodiment, the refrigerant flow holes 5 are arranged in one-to-one correspondence with the exhaust ports 3, and the diameter of the refrigerant flow holes 5 is larger than the diameter of the corresponding exhaust ports 3. In this embodiment, the diameter of the refrigerant flow holes 5 being larger than the diameter of the exhaust ports 3 can ensure that the refrigerant flow holes 5 do not block the exhaust ports 3 and do not hinder the normal flow of the refrigerant. The cross-sectional shape of the refrigerant flow holes 5 can be circular, diamond-shaped, parallelogram-shaped or other shapes. No matter which shape it is, it is necessary to completely clear the exhaust ports 3, that is, in the plane perpendicular to the central axis of the exhaust ports 3, the projection of the exhaust ports 3 is completely located within the projection of the refrigerant flow holes 5.

[0043] In one embodiment, the exhaust valve gasket 7 is adhesively fixed in the exhaust groove 6. The exhaust valve gasket 7 can also be fixedly arranged in the exhaust groove 6 by screws or rivets, etc., which can prevent the exhaust valve gasket 7 from moving together with the valve plate 4 during the movement of the valve plate 4, thereby improving the vibration damping effect of the exhaust valve gasket 7.

[0044] The shape of the exhaust valve gasket 7 can be C-shaped or strip-shaped, and its shape should be consistent with the shape of the exhaust groove 6 to ensure that the exhaust valve gasket 7 can fill the entire exhaust groove 6, so that the slapping force of the valve plate 4 basically completely acts on the exhaust valve gasket 7 instead of acting on the valve seat 2.

[0045] For the exhaust valve assembly with a single exhaust port 3, the exhaust valve gasket 7 can have a uniform thickness. For the exhaust valve assembly with non-single exhaust ports 3, the exhaust valve gasket 7 can have a uniform thickness, preferably a non-uniform thickness, and the thickness of the exhaust valve gasket 7 should be adapted to the exhaust pressure of the exhaust port 3 where the exhaust valve gasket 7 is located. The greater the exhaust pressure, the greater the thickness of the exhaust valve gasket 7, so as to match the slapping action of the valve plate 4 and generate a better vibration damping force.

[0046] In one embodiment, the exhaust valve assembly further includes a lift limiter 15 for limiting the upward lift stroke of the valve plate 4. When the valve plate 4 opens, the valve plate 4 warps upward around the lift limiter 15, and the lift limiter 15 plays a role in restricting the opening height of the valve plate 4, which can prevent the valve plate 4 from having too large an opening amplitude without opening limit, resulting in too short a fatigue life of the valve plate 4. The valve plate 4 and the lift limiter 15 are placed on the valve seat 2 in sequence from bottom to top and fixed to the valve seat 2 with rivets or screws.

[0047] In one embodiment, an annular protrusion 8 is provided on the periphery of the exhaust port 3, and the exhaust valve gasket 7 is supported on the annular protrusion 8 and forms a cavity with the bottom wall of the exhaust groove 6.

[0048] The exhaust valve gasket 7 is fixedly installed on the bottom wall of the exhaust groove 6 by screws or rivets. An annular protrusion 8 is provided on the periphery of the threaded hole of the exhaust groove 6, and the heights of the annular protrusions 8 are the same.

[0049] In this embodiment, two screw holes are added to the exhaust valve gasket 7, and corresponding screw holes are also added at the corresponding positions on the bottom of the exhaust groove 6. Screws can be used to fix the exhaust valve gasket 7 to the bottom wall of the exhaust groove 6. Annular protrusions 8 are provided on both the exhaust port 3 and the periphery of the screw holes, which can form a cavity between the exhaust valve gasket 7 and the bottom wall of the exhaust groove 6, thereby increasing the deformation amount of the exhaust valve gasket 7 and improving the vibration damping effect.

[0050] In one embodiment, a damping ring 9 is provided on the periphery of the refrigerant flow hole 5 on the side of the exhaust valve gasket 7 facing the valve plate 4, and the damping ratio of the damping ring 9 is greater than that of the exhaust valve gasket 7.

[0051] An annular groove 10 is provided on the periphery of the refrigerant flow hole 5 of the exhaust valve gasket 7, and the damping ring 9 is installed in the annular groove 10.

[0052] In this embodiment, a damping ring 9 is filled in the annular groove 10 of the exhaust valve gasket 7 for buffering. The damping ring 9 is made of PA, Mn-Cu alloy, thin steel sheet or other flexible materials, which has better vibration damping effect compared with other rigid materials. The damping ring 9 filled in the annular groove 10 can be filled with different materials according to the force condition of the slapping part. Flexible materials such as PA are used in the parts with greater force, and metal materials such as Mu-Cu alloy are used in the parts with smaller force. Specifically, from the center of the exhaust port 3 outwards, the force gradually decreases. PA material is used at the position where the inner ring is subject to greater force, and Mu-Cu alloy is used at the position where the outer ring is subject to smaller force.

[0053] In this embodiment, the damping ratio of the damping ring 9 is greater than that of the exhaust valve gasket 7, which can ensure that a damping material with a higher damping ratio is used at the position where the valve plate 4 has the greatest slapping effect on the periphery of the exhaust port 3, so as to more effectively absorb the slapping force of the valve plate 4 and play a better role in vibration damping and noise reduction.

[0054] In one embodiment, the structural strength of the exhaust valve gasket 7 is greater than that of the damping ring 9. In this embodiment, since the area of the exhaust valve gasket 7 is relatively large, in order to improve the durability of the exhaust valve gasket 7, the structural strength of the exhaust valve gasket 7 can be made greater than that of the damping ring 9, so as to balance the relationship between the area and the structural strength of the two.

[0055] In one embodiment, a damping groove 11 is provided on the periphery of the refrigerant flow hole 5 on the side of the exhaust valve gasket 7 facing the valve plate 4, and there is a preset interval between the damping groove 11 and the refrigerant flow hole 5. In this embodiment, a damping groove 11 is provided on the periphery of the refrigerant flow hole 5 of the exhaust valve gasket 7. The damping groove 11 is, for example, annular. When the valve plate 4 moves downward to slap the exhaust valve gasket 7, the damping groove 11 can form a certain air pressure, thus playing a role in buffering and vibration damping.

[0056] In one embodiment, a circumferentially extending hole 12 and a radially extending hole 13 are provided on the periphery of the refrigerant flow hole 5 of the exhaust valve gasket 7. The circumferentially extending hole 12 and the radially extending hole 13 are arranged alternately and at intervals in the circumferential direction, so as to form a flexible vibration damping structure around the exhaust port 3, which can further increase the deformation amount of the exhaust valve gasket 7, so as to better absorb the slapping energy of the valve plate 4.

[0057] In one embodiment, at least one side surface of the exhaust valve gasket 7 is coated with a damping coating 14. In this embodiment, the damping coating 14 is, for example, graphite, PTFE, etc., so as to further enhance the vibration damping ability of the exhaust valve gasket 7 and reduce the slapping force of the valve plate 4.

[0058] In one embodiment, there are at least two exhaust ports 3, which are arranged at intervals in sequence along the rotation direction of the crankshaft. The exhaust valve gasket 7 has a stepped structure, and each exhaust port 3 corresponds to a stepped height. Along the rotation direction of the crankshaft, the stepped height of the exhaust valve gasket 7 increases.

[0059] In this embodiment, taking the example that there are three exhaust ports 3 arranged at the bottom of the exhaust groove 6, the exhaust valve gasket 7 adopts a stepped unequal-thickness structure with three steps. Along the rotation direction of the crankshaft, the heights of the three steps are H1, H2, and H3 respectively. Since the refrigerant flow rates of the three exhaust ports 3 are different, the speeds at which the valve plate 4 strikes the exhaust valve gasket 7 are different. Therefore, in order to make the vibration damping ability of the exhaust valve gasket 7 match the speed at which the valve plate 4 strikes the exhaust valve gasket 7, thin materials can be used at positions with less force, and thick materials can be used at positions with greater force, so that H1 > H2 > H3, thereby achieving a better vibration damping effect by using an exhaust valve gasket 7 with unequal thicknesses.

[0060] Combined with reference to Figure 15 As shown, after adopting the exhaust valve assembly of the embodiment of the present application, the compressor can reduce the noise of the compressor within the range of 25 - 50 Hz, and has a significant noise reduction effect within the range of 35 - 45 Hz.

[0061] In this embodiment, taking a sliding vane compressor as an example, the compressor pump body is composed of an exhaust valve assembly, an upper flange, rollers, a crankshaft, sliding vanes, a cylinder, and a lower flange, which jointly complete the suction, compression, and exhaust work of the compressor. A closed cavity is formed between the upper flange, the cylinder, and the lower flange. The rotation of the crankshaft drives the sliding vanes to reciprocate in the cylinder to change the volume of the cavity to achieve the purpose of compressing gas. When the refrigerant is compressed to a certain pressure, the high-pressure gas will push open the valve plate 4 in the exhaust assembly through the exhaust port 3 for exhaust. When the exhaust is completed, the valve plate 4 moves downward under the action of the pressure difference and its own elastic deformation force to close the exhaust port 3, thereby completing the entire compression and exhaust work.

[0062] During the operation of the compressor, the valve plate 4 will perform a periodic opening and closing movement. When the valve plate 4 closes, the head of the valve plate 4 moves downward and strikes on the exhaust valve gasket 7. Since the exhaust valve gasket 7 uses a flexible damping material, the exhaust valve gasket 7 will produce varying degrees of deformation under the action of the striking force, and can play an effective role in buffering and vibration damping.

[0063] According to an embodiment of the present application, the compressor includes an exhaust valve assembly, and this exhaust valve assembly is the above-mentioned exhaust valve assembly.

[0064] According to an embodiment of the present application, the air conditioner includes an exhaust valve assembly, and this exhaust valve assembly is the above-mentioned exhaust valve assembly.

[0066] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application. The above is only the preferred implementation manner of the present application. It should be noted that for those of ordinary skill in the art, several improvements and modifications can be made without departing from the technical principle of the present application, and these improvements and modifications should also be regarded as the protection scope of the present application.
