[0043] Reference below Figure 1-Figure 10 A discharge valve assembly 30 for a compressor according to an embodiment of the present invention is described.

[0044] like Figure 1As shown, an exhaust valve assembly 30 for a compressor according to an embodiment of the present invention includes a valve seat 20, a valve plate 10 and a limiter 12, the valve seat 20 is configured with a receiving groove, the receiving groove has an exhaust hole 23, the valve plate 10 has a stopper 10c and the valve plate 10 is installed in the receiving groove, the stopper 10c is used to open and close the exhaust hole 23, the limiter 12 has a limiter 12c and the limiter 12 is installed in the receiving groove, the limiter 12 is arranged on the side of the valve plate 10 away from the valve seat 20 to limit the stroke of the valve plate 10, wherein the valve plate 10 and the limiter 12 are an integral part.

[0045] Specifically, during the assembly of the exhaust valve assembly 30, the valve disc 10 and the stopper 12 are first fixedly connected to form an integral part, and then the valve disc 10 and the stopper 12 are installed on the valve seat 20 together. The valve disc 10 is located in the receiving groove and can reciprocate between the stopper 12 and the valve seat 20 through its own deformation. When the valve disc 10 fits the exhaust hole 23, the stopper 10c closes the exhaust hole 23. When the valve disc 10 fits the stopper 12, the stopper 10c opens the exhaust hole 23 and the stopper 10c reaches the maximum stroke relative to the exhaust hole 23. It is worth noting that the concentricity of the stopper 10c and the exhaust hole 23 will affect the service life of the valve disc 10 to a certain extent, so during the assembly process, the center of the stopper 10c is made to fit the center of the exhaust hole 23 as much as possible.

[0046] like Figure 6 As shown, Figure 6 The (L) graph and Figure 6 The concentricity between the stopper 10 c and the exhaust hole 23 in the (R) figure is poor. During the reciprocating motion of the exhaust valve, the stress on the stopper 10 c is concentrated at the X position, so the stopper 10 c is more likely to be damaged. Figure 6 In the figure (M), the concentricity between the stopper 10 c and the exhaust hole 23 is relatively high, and the stress distribution on the stopper 10 c is relatively uniform, thereby reducing the probability of damage to the stopper 10 c.

[0047] According to the exhaust valve assembly 30 for a compressor of the embodiment of the present invention, the stopper 12 and the valve plate 10 are fixedly connected to form an integral structure, and then the stopper 12 and the valve plate 10 are installed on the valve seat 20 together. Compared with the exhaust valve assembly in the related art, which requires the stopper and the valve plate to be assembled with the valve seat respectively, and the valve plate and the stopper need to be adjusted separately, the concentricity is low and the assembly is more complicated, the exhaust valve assembly 30 of the embodiment of the present invention only needs to adjust the integral structure of the stopper 12 and the valve plate 10 once, which is more convenient to assemble and can reduce The error generated during the assembly process between the small stopper 10c and the exhaust hole 23, the concentricity of the stopper 10c and the exhaust hole 23 is relatively high, and it is easy to achieve the concentric setting of the stopper 10c and the exhaust hole 23. Since the valve plate 10 is in a high-frequency motion state during operation, the impact force with the valve seat 20 is relatively large. Therefore, improving the concentricity of the stopper 10c and the exhaust hole 23 is beneficial to uniformly distribute the stress on the stopper 10c, thereby reducing the probability of damage to the stopper 10c, extending the service life of the valve plate 10, and ensuring the long-term operation of the exhaust valve assembly 30.

[0048] Therefore, the exhaust valve assembly 30 according to the embodiment of the present invention has the advantages of high assembly accuracy, convenient installation, long service life, etc.

[0049] In some embodiments of the present invention, the valve plate 10 and the stopper 12 are connected together by spot welding. Specifically, the valve plate 10 and the stopper 12 can be fixedly connected by resistance spot welding or laser spot welding. Preferably, resistance spot welding is used for fixed connection, which is convenient to manufacture and has low cost.

[0050] Alternatively, if Figure 4 As shown, the stopper 10c is concentrically arranged with the limiting portion 12c and the diameter of the stopper 10c is less than or equal to the diameter of the limiting portion 12c. Specifically, the stopper 10c and the limiting portion 12c are both circular and concentrically arranged, so that the concentricity of the valve disc 10 and the limiter 12 is relatively high. After being assembled on the valve seat 20, the concentricity of the valve disc 10 and the receiving groove can be adjusted by adjusting the concentricity of the limiter 12 and the receiving groove, and the core adjustment is relatively convenient. Furthermore, the diameter of the limiting portion 12c is greater than or equal to the diameter of the stopper 10c. When the stopper 10c and the limiting portion 12c collide, the stress on the stopper 10c is relatively uniform, thereby playing a role in protecting the stopper 10c.

[0051] Furthermore, if Figure 3 As shown, the valve plate 10 is constructed as a symmetrical structure in its width direction, and the stopper 12 is constructed as a symmetrical structure in its width direction. The center line of the valve plate 10 is arranged to coincide with the center line of the stopper 12, that is, Figure 3The position of the center line XX. In this way, the concentricity between the valve plate 10 and the stopper 12 can be further improved, thereby improving the concentricity between the valve plate 10 and the exhaust hole 23.

[0052] According to some embodiments of the present invention, Figure 2 and Figure 3 As shown, the valve disc 10 is provided with a first mounting hole 13, the stopper 12 is provided with a second mounting hole, the first mounting hole 13 and the second mounting hole are arranged to overlap, and the valve disc 10 and the stopper 12 are installed on the valve seat 20 through the first mounting hole 13 and the second mounting hole. Specifically, one end of the valve disc 10 is provided with the first mounting hole 13, one end of the stopper 12 is provided with the second mounting hole, the bottom wall 22 of the receiving groove is provided with an assembly hole 27, and the fastener 28 passes through the first mounting hole 13 and the second mounting hole and cooperates with the assembly hole 27 to fix the valve disc 10 and the stopper 12 to the valve seat 20. In some examples of the present invention, the fastener 28 can be a rivet or a screw.

[0053] Furthermore, the storage groove includes a circular groove 25 and a rectangular groove 26 , the circular groove 25 is used to accommodate the stopper portion 10 c , and the rectangular groove 26 is used to accommodate the wide portion 10 a and the narrow portion 10 b , wherein the exhaust hole 23 is provided on the bottom wall of the circular groove 25 .

[0054] Alternatively, if Figure 2 As shown, the valve plate 10 includes a wide portion 10a and a narrow portion 10b, the first mounting hole 13 is provided in the wide portion 10a, one end of the narrow portion 10b is connected to the wide portion 10a and the other end is connected to the stop portion 10c, and the width of the narrow portion 10b is smaller than the width of the wide portion 10a.

[0055] Specifically, in Figure 2 In the illustrated embodiment, the length of the wide portion 10a is A, the length of the narrow portion 10b is B, and the length of the stop portion 10c is C. The wide portion 10a is fixed between the limiter 12 and the valve seat 20. During the operation of the exhaust valve assembly 30, the narrow portion 10b and the stop portion 10c reciprocate relative to the wide portion 10a through their own deformation to open and close the exhaust hole 23. Since the width W2 of the wide portion 10a is significantly larger than the width of the narrow portion 10b, the narrow portion 10b has better deformation ability, so that the narrow portion 10b will not easily break under high-frequency movement. Furthermore, the width of the wide portion 10a is larger, and the contact area between the wide portion 10a and the limiter 12 and the wide portion 10a and the valve seat 20 is larger, so that the stress distribution on the wide portion 10a is more uniform and the force condition is better.

[0056] Further, continue to refer to Figure 2In the embodiment shown, the connection between the wide portion 10a and the narrow portion 10b and the connection between the narrow portion 10b and the stopper 10c are arc transitions. Specifically, the connection between the wide portion 10a and the narrow portion 10b is rounded after tumbling, and the radius of the rounded corner is r2; the connection between the narrow portion 10b and the stopper 10c is rounded after tumbling, and the radius of the rounded corner is r1. In this way, the stress concentration at the connection between the wide portion 10a and the narrow portion 10b and the connection between the narrow portion 10b and the stopper 10c can be reduced, thereby reducing the risk of the valve plate 10 breaking.

[0057] According to some embodiments of the present invention, Figure 3 As shown, the stopper 12 includes a fixed portion 12a and an inclined portion 12b, the wide portion 10a is attached to the fixed portion 12a, the second mounting hole is provided in the fixed portion 12a and the lower surface of the fixed portion 12a is attached to the bottom wall 22 of the storage groove, one end of the inclined portion 12b is connected to the fixed portion 12a, and the other end of the inclined portion 12b is connected to the limit portion 12c. Specifically, as Figure 3 As shown, the length of the fixed portion 12a is A, the length of the inclined portion 12b and the limiting portion 12c is D, the fixed portion 12a is fixedly connected to the wide portion 10a by spot welding, and then installed on the valve seat 20 through the first mounting hole 13 and the second mounting hole, as shown in FIG. Figure 5 As shown, the inclined portion 12b and the limiting portion 12c are inclined relative to the fixed portion 12a to limit the travel of the valve plate 10. Preferably, the limiter 12 is made of a steel plate with a thickness of 2.6-3.0 mm, which is processed by stamping and then rolling.

[0058] Alternatively, if Figure 5 As shown, the exhaust hole 23 is provided on the bottom wall 22 of the receiving groove, and the periphery of the exhaust hole 23 has a matching edge 24 extending upward, and when the valve plate 10 closes the exhaust hole 23, the stopper 10c covers the matching edge 24. Specifically, the periphery of the exhaust hole 23 extends upward to form the matching edge 24, and when the valve plate 10 closes the exhaust hole 23, the stopper 10c covers the upper end of the matching edge 24, thereby, the stopper 10c has a better closing effect on the exhaust hole 23.

[0059] Furthermore, if Figure 4 As shown, the width of the fixed portion 12a is equal to the width of the wide portion 10a. Therefore, the center lines of the valve plate 10 and the stopper 12 can be made to coincide by aligning the fixed portion 12a and the wide portion 10a. After the valve plate 10 and the stopper 12 are installed on the valve seat 20, it is convenient to perform center alignment, and the concentricity of the stopper portion 10c and the exhaust hole 23 is relatively high.

[0060] According to some embodiments of the present invention, Figure 7 and Figure 8As shown in FIG. 3 (the reference numeral 35 is the exhaust valve assembly in the embodiment of the invention), the width of at least a portion of the inclined portion 12b is equal to the width of the receiving groove. Specifically, the portion of the inclined portion 12b adjacent to the limiting portion 12c is the embedded portion 12d, and the width of the embedded portion 12d is W1 and equal to the width of the receiving groove. After the stopper 12 is assembled on the valve seat 20, the portion 12d of the inclined portion 12b adjacent to the limiting portion 12c is embedded in the receiving groove and will not move relative to the receiving groove in the width direction. In this way, the positioning effect of the stopper 12 in the width direction is good, which is conducive to improving the concentricity of the stopper 10c and the exhaust hole 23.

[0061] Optionally, the ratio of the distance L between the second mounting hole and the embedded portion 12d to the width W1 of the embedded portion 12d is greater than or equal to 3. In this way, the distance L between the second mounting hole and the embedded portion 12d is longer than the width W1 of the embedded portion 12d, which is beneficial to improving the concentricity of the stopper 12 and the valve plate 10 relative to the receiving groove, and the alignment is more convenient.

[0062] In some examples of the present invention, continue to refer to Figure 7 and Figure 8 In the embodiment shown, the connection between the fixed portion 12a and the wide portion 10a is formed as a connection area 32, the connection area 32 is circular and is arranged adjacent to the first mounting hole 13 or the second mounting hole, and the connection area 32 is located between the first mounting hole 13 and the stopper 10c or between the second mounting hole and the limiting portion 12c. Specifically, the connection area 32 is a spot welding area of ​​the fixed portion 12a and the wide portion 10a, the connection area 32 is circular and is arranged adjacent to the first mounting hole 13 or the second mounting hole, the center of the connection area 32 is located on the center line of the valve plate 10 and the center line of the limiter 12, and the connection area 32 is located on the side of the first mounting hole 13 or the second mounting hole adjacent to the stopper 10c.

[0063] In other examples of the present invention, Fig. 9 As shown, the connection between the fixing portion 12a and the wide portion 10a is formed as a connection area 32, and the connection area 32 is in the shape of a ring surrounding the first mounting hole 13 or the second mounting hole. In this way, the connection area 32 can be located directly below the head of the fastener 28 that matches the first mounting hole 13 and the second mounting hole. The downward pressure of the head of the fastener 28 on the stopper 12 can further improve the fixing effect of the valve plate 10 and the stopper 12. Furthermore, during the spot welding process, the positive electrode and the negative electrode of the electric welder are suitable for extending into the first mounting hole 13 and the second mounting hole for welding, thereby reducing the difficulty of spot welding.

[0064] Optionally, continue to refer to Fig. 9In the embodiment shown, a notch 11 is provided at one end of the valve plate 10 away from the stopper 10c. The notch 11 is a bevel formed when the valve plate 10 is punched and cut, and the notch 11 generates fewer burrs during punching and cutting. The upper and lower surfaces of the valve plate 10 can be identified through the notch 11, so as to facilitate the assembly of the valve plate 10 and the stopper 12.
