[0026] The valve assembly 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0027] like Figure 1 As shown, the valve assembly component 100 according to an embodiment of the present invention includes a valve plate 1 and an exhaust valve plate 2.

[0028] Specifically, the valve assembly 100 is used in a compressor, such as Figure 1 and Figure 3 As shown, the valve plate 1 is provided with two exhaust holes 111, and the exhaust valve plate 2 is provided in the thickness direction of the valve plate 1 (as shown in FIG. Figure 1 On one side of the third direction (shown in FIG), the exhaust valve plate 2 includes an assembly portion 21 and two exhaust portions 22. The two exhaust portions 22 are respectively arranged opposite to the two exhaust holes 111 and are used to open or close the exhaust holes 111.

[0029] It can be understood that the exhaust valve plate 2 is a spring plate with a certain elastic force. The valve plate 1 and the exhaust valve plate 2 together define the exhaust valve. When the piston of the compressor moves upward, the exhaust part 22 opens the exhaust hole 111 to discharge the compressed high-temperature and high-pressure refrigerant out of the cylinder.

[0030] In addition, by providing two exhaust holes 111, the exhaust speed can be effectively accelerated and the exhaust efficiency can be improved. The exhaust valve plate 2 includes an assembly portion 21 and two exhaust portions 22. The two exhaust portions 22 are respectively arranged opposite the two exhaust holes 111, which slows down the flapping speed of the exhaust valve plate 2, prevents the exhaust portions 22 from continuously flapping against the valve plate 1 at a high frequency, avoids vibration of the exhaust valve plate 2, avoids the generation of aerodynamic noise, and prevents wear of the exhaust valve plate 2, thereby increasing the service life of the compressor.

[0031] The direction of the line connecting the center points of the two exhaust holes 111 is the first direction (eg Figure 1 As shown in the first direction, along the first direction, the assembly portion 21 is arranged between the two exhaust holes 111 and is fixedly connected to the valve plate 1, and the two exhaust portions 22 are arranged at both ends of the assembly portion 21 along the first direction and are connected to the assembly portion 21, so that the assembly process of the exhaust valve plate 2 and the valve plate 1 is relatively simple and convenient.

[0032] According to the valve assembly component 100 of the embodiment of the present invention, by setting two exhaust holes 111 on the valve plate 1, the exhaust speed can be effectively accelerated and the exhaust efficiency can be improved. The exhaust valve plate 2 includes an assembly portion 21 and two exhaust portions 22. The two exhaust portions 22 are respectively arranged opposite to the two exhaust holes 111, which slows down the flapping speed of the exhaust valve plate 2, avoids the exhaust portion 22 from continuously flapping the valve plate 1 at a high frequency, avoids damage to the exhaust valve plate 2, and improves the service life of the compressor. At the same time, the assembly portion 21 is arranged between the two exhaust holes 111 and is fixedly connected to the valve plate 1. The two exhaust portions 22 are arranged at both ends of the assembly portion 21 along the first direction and are connected to the assembly portion 21. The two exhaust portions 22 are respectively arranged opposite to the two exhaust holes 111, and are used to open or close the exhaust holes 111, so that the assembly process of the exhaust valve plate 2 and the valve plate 1 is relatively simple and convenient.

[0033] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, the assembly portion 21 and the two exhaust portions 22 are integrally formed. When the valve group component 100 is assembled, the exhaust valve sheet 2 and the valve plate 1 can be assembled by simply matching the assembly portion 21 with the valve plate 1, thereby simplifying the assembly process of the valve group component 100 and reducing the manufacturing cost of the valve group component 100.

[0034] In some embodiments of the present invention, Figure 1 and Figure 5As shown, the valve assembly component 100 also includes a lift limiter 3. The lift limiter 3 is arranged on the side of the exhaust valve plate 2 in the thickness direction away from the exhaust hole 111. When the compressor is working, the exhaust valve plate 2 will open quickly under the action of the airflow. The exhaust valve plate 2 may be over-opened due to inertia or airflow impact, exceeding the elastic limit of the exhaust valve plate 2, causing the exhaust valve plate 2 to deform or break. At the same time, it may prolong the return time of the exhaust valve plate 2 and delay the closing of the exhaust hole 111, affecting the compression efficiency of the compressor. By providing the lift limiter 3, the exhaust valve plate 2 can be limited when the exhaust portion 22 moves in the direction away from the exhaust hole 111, reducing the risk of the exhaust valve plate 2 breaking and deforming, and avoiding affecting the compression efficiency of the compressor.

[0035] The lift limiter 3 extends along a first direction and includes a mounting portion 31 and two limiting arms 32. The mounting portion 31 is disposed opposite the assembly portion 21 and fixedly connected to the valve plate 1. The two limiting arms 32 are disposed at both ends of the mounting portion 31 along the first direction and are connected to the mounting portion 31. The two limiting arms 32 are respectively disposed opposite the two exhaust holes 111, and the exhaust portions 22 are movably disposed between the valve plate 1 and the corresponding limiting arms 32. The two limiting arms 32 respectively limit the two exhaust portions 22, thereby reducing the risk of fracture and deformation of the two exhaust portions 22, thereby increasing the reliability of the compressor's compression efficiency.

[0036] In this embodiment, along the thickness direction of the valve plate 1, the gap between the limiting arm 32 and the exhaust hole 111 is larger than the gap between the mounting portion 31 and the exhaust hole 111, so that the limiting arm 32 reserves sufficient space for the movement of the exhaust portion 22, thereby avoiding smooth exhaust of the exhaust hole 111.

[0037] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, a limiting groove 11 is provided at one end of the valve plate 1 in the thickness direction, an exhaust hole 111 is provided on the bottom wall of the limiting groove 11 , and the exhaust valve plate 2 and the lift limiter 3 are both provided in the limiting groove 11 .

[0038] It can be understood that the compressor includes a cylinder and a cylinder head, and the valve group component 100 is arranged between the cylinder and the cylinder head. By setting a limit groove 11 in a section of the thickness direction of the valve plate 1, and the exhaust valve plate 2 and the lift limiter 3 are both arranged in the limit groove 11, the overall volume of the valve group component 100 can be reduced and the adaptability of the valve group component 100 can be increased.

[0039] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, a plurality of limiting protrusions 112 are provided on the bottom wall of the limiting groove 11. The plurality of limiting protrusions 112 are provided between the two exhaust holes 111. The plurality of limiting protrusions 112 include two groups of limiting protrusions 112. Figure 1In the second direction shown, two sets of limiting protrusions 112 are arranged opposite each other. Along the first direction, each set of limiting protrusions 112 includes two limiting protrusions 112 located on either side of the assembly portion 21. Along the first direction, the limiting protrusions 112 and the assembly portion 21 form an interference fit. The first and second directions are perpendicular to the thickness of the valve plate 1. In this manner, the limiting protrusions 112 can limit the assembly portion 21 in both the second and first directions, preventing undesirable displacement of the exhaust valve disc 2 during operation, thereby preventing exhaust failure of the compressor and increasing the reliability of the compressor.

[0040] In the present invention, there is no restriction on the shape of the limiting protrusion 112 . In the projection in the thickness direction of the valve plate 1 , the limiting protrusion 112 can be square, fan-shaped, or other shapes, as long as it does not interfere with the exhaust valve plate 2 .

[0041] In some embodiments of the present invention, Figure 1 and Figure 5 As shown, elastic arms 311 are provided at both ends of the mounting portion 31 along the second direction. Along the second direction, each group of limiting protrusions 112 and the limiting groove 11 jointly define a mounting groove. The elastic arms 311 provided on the same side of the mounting portion 31 along the second direction are interference fit with the side walls of the corresponding mounting groove. The assembly of the mounting portion 31 and the limiting groove 11 is relatively simple and reliable.

[0042] In this embodiment, limit blocks 312 are further provided at both ends of the mounting portion 31 along the second direction. The limit blocks 312 are arranged in the mounting groove. Elastic arms 311 are provided at both ends of the limit blocks 312 along the first direction. The elastic arms 311 and the limit blocks 312 jointly limit the mounting portion 31, so that the mounting portion 31 and the valve plate 1 fit more tightly.

[0043] In some embodiments of the present invention, along the thickness direction of the valve plate 1, the end surface of the limiting arm 32 away from the exhaust hole 111 does not exceed the end surface of the valve plate 1 at one end where the limiting groove 11 is provided, which can further reduce the overall volume of the valve group component 100 and increase the adaptability of the valve group component 100.

[0044] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the valve group component 100 also includes an intake valve plate 4, which is arranged at the end of the valve plate 1 in the thickness direction away from the exhaust valve plate 2. The valve plate 1 is provided with an intake hole 12. The intake valve plate 4 includes a valve plate body 41 and a valve tongue 42. The valve tongue 42 is used to open or close the intake hole 12.

[0045] It can be understood that the intake valve plate 4 is a spring plate with a certain elastic force. The valve plate 1 and the intake valve plate 4 jointly define the intake valve. When the piston of the compressor moves downward, the valve tongue 42 of the intake valve plate 4 automatically opens the intake hole 12 under the action of the pressure difference between the inside and outside of the cylinder, allowing low-temperature and low-pressure gaseous refrigerant to enter the cylinder.

[0046] The valve plate body 41 is provided with a first mounting hole 46, the valve tongue 42 is arranged in the first mounting hole 46 and one end of the valve tongue 42 in the longitudinal direction is connected to the hole wall of the first mounting hole 46, and a valve gap 421 is provided between the remaining part of the valve tongue 42 and the hole wall of the first mounting hole 46 to facilitate the movement of the valve tongue 42 and to facilitate the valve tongue 42 to switch between opening and closing the suction hole 12.

[0047] Two exhaust holes 44 are provided on the valve body 41 . The two exhaust holes 44 are respectively arranged opposite to the two exhaust holes 111 to prevent the valve body 41 from affecting the exhaust of the compressor.

[0048] In this embodiment, Figure 1-Figure 3 As shown, a first assembly hole 13 is provided on the valve plate 1, and a second assembly hole 45 is provided on the intake valve plate 4. The fastener passes through the second assembly hole 45 and the first assembly hole 13 and is fastened to the cylinder head to realize the assembly of the valve group component 100 and the cylinder head.

[0049] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the exhaust hole 44 is connected to the valve gap 421, which can reduce the clearance during the compressor exhaust process, thereby effectively increasing the exhaust volume. At the same time, it is convenient to process the holes and gaps on the intake valve plate 4 at one time.

[0050] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the intake valve plate 4 also includes a fixing portion 43, and the valve tongue 42 is provided with a second mounting hole 47. The fixing portion 43 is arranged in the second mounting hole 47 and one end of the fixing portion 43 in the length direction is connected to the hole wall of the second mounting hole 47. There is a gap between the fixing portion 43 and the hole wall of the first mounting hole 46, so that the connection area between the valve tongue 42 and the valve plate body 41 is smaller, so that the resistance of the valve tongue 42 during movement is smaller, thereby increasing the efficiency of the valve tongue 42 in opening or closing the intake hole 12.

[0051] In the projection of the valve plate 1 in the thickness direction, the fixing portion 43 is spaced apart from the air intake hole 12 to prevent the fixing portion 43 from affecting the exhaust of the compressor.

[0052] In addition, under the test conditions of refrigerant R600a, compressor speed of 50 Hz, suction pressure of 0.0511 MPa, suction temperature of 45°C, exhaust pressure of 0.5038 MPa, and exhaust temperature of 95.16°C, the simulation results of the prior art and the present invention are shown in Table 1: Table 1 Comparison of simulation results between the prior art and this embodiment

[0053] It can be seen that, compared with the prior art, the cooling capacity of this embodiment is increased by 1.53W, and the COP (Coefficient of Performance) is increased by 0.01, which effectively improves the energy efficiency of the compressor.

[0054] At the same time, under the above working conditions, the maximum bending stress of the exhaust valve plate 2 decreased by 58.12 MPa, and the exhaust velocity decreased by 2.13 m / s.

[0055] The following describes a valve assembly component 100 according to a specific embodiment of the present invention with reference to the accompanying drawings. It should be understood that the following description is merely exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0056] like Figure 1 As shown, the valve assembly component 100 according to an embodiment of the present invention includes a valve plate 1, an exhaust valve plate 2, a lift limiter 3 and an intake valve plate 4.

[0057] Specifically, the valve assembly component 100 is used in a compressor. The valve plate 1 is provided with two exhaust holes 111. The exhaust valve disc 2 is provided on one side of the valve plate 1 in the thickness direction. The exhaust valve disc 2 includes an assembly portion 21 and two exhaust portions 22. The two exhaust portions 22 are respectively arranged opposite the two exhaust holes 111 and are used to open or close the exhaust holes 111. The exhaust valve disc 2 is a spring plate with a certain elastic force. The valve plate 1 and the exhaust valve disc 2 together define an exhaust valve. When the piston of the compressor moves upward, the exhaust portion 22 opens the exhaust holes 111 and discharges the compressed high-temperature and high-pressure refrigerant from the cylinder. The direction of the line connecting the center points of the two exhaust holes 111 is a first direction. Along the first direction, the assembly portion 21 is provided between the two exhaust holes 111 and is fixedly connected to the valve plate 1. The two exhaust portions 22 are provided at both ends of the assembly portion 21 along the first direction and are connected to the assembly portion 21, making the assembly process of the exhaust valve disc 2 and the valve plate 1 relatively simple and convenient. A limiting groove 11 is provided at one end of the valve plate 1 in the thickness direction. The exhaust hole 111 is provided on the bottom wall of the limiting groove 11 . The exhaust valve plate 2 and the lift limiter 3 are both provided in the limiting groove 11 .

[0058] The assembly portion 21 and the two exhaust portions 22 are integrally formed. When the valve assembly component 100 is assembled, the exhaust valve sheet 2 and the valve plate 1 can be assembled by simply matching the assembly portion 21 with the valve plate 1, thereby simplifying the assembly process of the valve assembly component 100 and reducing the manufacturing cost of the valve assembly component 100.

[0059] The lift limiter 3 is arranged on the side of the exhaust valve plate 2 in the thickness direction away from the exhaust hole 111. It can limit the exhaust valve plate 2 when the exhaust part 22 moves in the direction away from the exhaust hole 111, reducing the risk of breakage and deformation of the exhaust valve plate 2 and avoiding affecting the compression efficiency of the compressor.

[0060] The lift limiter 3 extends along a first direction and includes a mounting portion 31 and two limiting arms 32. The mounting portion 31 is disposed opposite the assembly portion 21 and fixedly connected to the valve plate 1. The two limiting arms 32 are disposed at both ends of the mounting portion 31 along the first direction and are connected to the mounting portion 31. The two limiting arms 32 are disposed opposite the two exhaust holes 111, respectively. The exhaust portion 22 is movably disposed between the valve plate 1 and the corresponding limiting arms 32. Along the thickness direction of the valve plate 1, the gap between the limiting arms 32 and the exhaust hole 111 is greater than the gap between the mounting portion 31 and the exhaust hole 111. This allows the limiting arms 32 to reserve sufficient space for the movement of the exhaust portion 22, preventing unsmooth exhaust from the exhaust hole 111. The two limiting arms 32 respectively limit the two exhaust portions 22, reducing the risk of fracture or deformation of both exhaust portions 22, thereby increasing the reliability of the compressor's compression efficiency.

[0061] The bottom wall of the limiting groove 11 is provided with a plurality of fan-shaped limiting protrusions 112. The limiting protrusions 112 include two groups of limiting protrusions 112. Along the second direction, the two groups of limiting protrusions 112 are arranged opposite each other. Along the first direction, each group of limiting protrusions 112 includes two limiting protrusions 112 provided on either side of the assembly portion 21. Along the first direction, the limiting protrusions 112 and the assembly portion 21 have an interference fit. The first direction, the second direction, and the thickness direction of the valve plate 1 are perpendicular to each other. In this case, the limiting protrusions 112 can limit the assembly portion 21 in both the second direction and the first direction, preventing the exhaust valve plate 2 from moving unnecessarily during operation, thus preventing exhaust failure of the compressor and increasing the reliability of the compressor.

[0062] Elastic arms 311 and limit blocks 312 are provided at both ends of the mounting portion 31 along the second direction. Along the second direction, each group of limit protrusions 112 and the limit groove 11 jointly define a mounting groove. The elastic arms 311 provided on the same side of the mounting portion 31 along the second direction are interference fit with the side walls of the corresponding mounting grooves. The limit blocks 312 are provided in the mounting grooves. Elastic arms 311 are provided at both ends of the limit blocks 312 along the first direction. The elastic arms 311 and the limit blocks 312 jointly limit the mounting portion 31, so that the mounting portion 31 and the valve plate 1 fit more tightly.

[0063] The end surface of the limiting arm 32 away from the exhaust hole 111 does not exceed the end surface of the valve plate 1 provided with the limiting groove 11, which can further reduce the overall volume of the valve assembly component 100 and increase the adaptability of the valve assembly component 100.

[0064] The valve assembly 100 also includes an intake valve disc 4, which is positioned at the end of the valve plate 1 in the thickness direction, facing away from the exhaust valve disc 2. The valve plate 1 is provided with an intake hole 12. The intake valve disc 4 includes a valve disc body 41 and a valve tongue 42, which is used to open or close the intake hole 12. The valve disc body 41 has a first mounting hole 46. The valve tongue 42 is positioned within the first mounting hole 46, with one end of the valve tongue 42 connected to the wall of the first mounting hole 46. A valve gap 421 is defined between the remaining portion of the valve tongue 42 and the wall of the first mounting hole 46 to facilitate movement of the valve tongue 42 and switch between opening and closing the intake hole 12. The valve disc body 41 has two exhaust holes 44, which are positioned opposite the two exhaust holes 111, respectively, to prevent the valve disc body 41 from interfering with the compressor exhaust. The exhaust holes 44 communicate with the valve gap 421, reducing clearance during the compressor exhaust process, thereby effectively increasing exhaust volume. At the same time, it is convenient to process the holes and gaps on the intake valve plate 4 at one time.

[0065] The intake valve disc 4 also includes a fixing portion 43. The valve tongue 42 is provided with a second mounting hole 47. The fixing portion 43 is disposed within the second mounting hole 47, and one end of the fixing portion 43 in the longitudinal direction is connected to the hole wall of the second mounting hole 47. A gap exists between the fixing portion 43 and the hole wall of the first mounting hole 46. This reduces the connection area between the valve tongue 42 and the valve disc body 41, resulting in less resistance to the movement of the valve tongue 42 and increasing the efficiency of the valve tongue 42 in opening or closing the intake hole 12. In the projection of the thickness direction of the valve plate 1, the fixing portion 43 is spaced apart from the intake hole 12 to prevent the fixing portion 43 from affecting the compressor exhaust.

[0066] The compressor according to the embodiment of the present invention includes the valve assembly 100 described above.

[0067] According to the compressor of the embodiment of the present invention, by arranging two exhaust holes 111 on the valve plate 1, the exhaust speed can be effectively accelerated and the exhaust efficiency can be improved. The exhaust valve plate 2 includes an assembly portion 21 and two exhaust portions 22. The two exhaust portions 22 are respectively arranged opposite to the two exhaust holes 111, which slows down the flapping speed of the exhaust valve plate 2, avoids the exhaust portion 22 from continuously flapping the valve plate 1 at a high frequency, avoids damage to the exhaust valve plate 2, and improves the service life of the compressor. At the same time, the assembly portion 21 is arranged between the two exhaust holes 111 and is fixedly connected to the valve plate 1. The two exhaust portions 22 are arranged at both ends of the assembly portion 21 along the first direction and are connected to the assembly portion 21. The two exhaust portions 22 are respectively arranged opposite to the two exhaust holes 111, and are used to open or close the exhaust holes 111, so that the assembly process of the exhaust valve plate 2 and the valve plate 1 is relatively simple and convenient.
