Among the present domestic compressor, reduce the noise between discharge valve piece and the lift stopper through the mode that sets up damping portion and spacing post on the cylinder head, because spacing post passes through detachable construction with the cylinder head and is connected for required part is many, and the structure is complicated, and the height of lifting up of discharge valve piece is limited, and then has reduced the compressor displacement, and discharge valve piece and spacing post contact force are big, and the noise reduction effect is not obvious. The invention creatively provides a cylinder cover assembly, which comprises an exhaust valve plate and a cover body; a lift limiter is formed on the cover body and provided with a magnetic part, and the magnetic part and the head of the exhaust valve plate have homopolar magnetism; when the cylinder cover assembly exhausts, the magnetic component and the exhaust valve plate are mutually exclusive, and when the exhaust valve plate is closer to the lift limiter, the lifting speed of the exhaust valve plate is smaller, so that the impact force of the exhaust valve plate on the lift limiter is reduced, and the noise generated when the exhaust valve plate collides with the lift limiter is further reduced; the service life of the exhaust valve plate and the lift limiter is prolonged, the number of required parts is small, the structure is simple, and the noise reduction effect is obvious.
As shown in fig. 1, 2a, 2b and 3, the present embodiment provides a cylinder head assembly including a discharge valve sheet 3 and a cover body 1; a lift limiter 11 is formed on the cover body 1; the lift limiter 11 is provided with a magnetic component 2, and the magnetic component 2 and the head of the exhaust valve plate 3 have homopolar magnetism; specifically, the cover body 1 is a key part of the compressor, can isolate the gas in a high-pressure area and a low-pressure area, smoothly completes the air suction and exhaust processes, the lift limiter 11 is positioned in the high-pressure exhaust area and mainly used for limiting the lifting height of the exhaust valve plate 3 in the exhaust process and avoiding delay when the exhaust is finished, and the cover body 1 and the lift limiter 11 are integrally formed; the magnetic part 2 is a permanent magnet, and when the magnetic part 2 is an N pole, the exhaust valve plate 3 is also an N pole; when the magnetic component 2 is S pole, the air release valve plate 3 is also S pole, so that when the air release valve plate 3 is close to the magnetic component 2, repulsive force is formed between the air release valve plate 3 and the magnetic component 2;
when the cylinder cover assembly exhausts, the magnetic part 2 and the exhaust valve sheet 3 repel each other, so that when the exhaust valve sheet 3 is closer to the lift limiter 11, the lifting speed of the exhaust valve sheet 3 is smaller, the impact force of the exhaust valve sheet 3 on the lift limiter 11 is reduced, the noise generated when the exhaust valve sheet 3 contacts with the lift limiter 11 is reduced, the stress conditions of the exhaust valve sheet 3 and the lift limiter 11 are improved, and the service lives of the exhaust valve sheet 3 and the lift limiter 11 are prolonged.
In order to ensure that the magnetic component 2 is reliably connected with the lift limiter 11, one end, facing the exhaust valve plate 3, of the lift limiter 11 is provided with a mounting position, and the mounting position is provided with a structure matched with the magnetic component 2; the magnetic member 2 is fitted to the mounting site, and the magnetic member 2 is mounted to the mounting site.
Preferably, as shown in fig. 2a, 2b and 3, the mounting position is formed by a limit groove 111 where one end surface of the lift limiter 11 is recessed toward the other end surface of the lift limiter 11, and the depth of the limit groove 111 is greater than the thickness of the magnetic member 2; when the magnetic component 2 is embedded in the limiting groove 111, one end face of the lift limiter 11 protrudes out of the end face of the magnetic component 2, the magnetic component 2 does not influence the lifting height of the exhaust valve plate 3, and the exhaust volume of the compressor is not changed; specifically, the side surface of the limiting groove 111 and the side surface of the magnetic part 2 have a matched structure, the outer contour size of the magnetic part 2 is smaller than the contour size of the limiting groove 111, when the magnetic part 2 is embedded in the limiting groove 111, the limiting groove 111 plays a good limiting role on the magnetic part 2, and a certain gap is formed between the magnetic part 2 and the limiting groove 111, so that the magnetic part 2 is convenient to mount and dismount; the design of the limit groove 111 reduces the contact surface between the exhaust valve plate 3 and the lift limiter 11, and when the exhaust valve plate 3 is separated from the lift limiter 11, the viscous force of lubricating oil between the exhaust valve plate 3 and the lift limiter 11 is reduced, and the response speed of the exhaust valve plate 3 is improved.
In order to enable the exhaust valve plate 3 to be stressed uniformly when the cylinder cover assembly exhausts, the end face, facing the exhaust valve plate 3, of the lift limiter 11 is arranged in an inclined mode, and correspondingly, the end face, facing the exhaust valve plate 3, of the magnetic component 2 is parallel to the end face, facing the exhaust valve plate 3, of the lift limiter 11; when the cylinder cover component exhausts, the gas in the gap between the magnetic component 2 and the exhaust valve plate 3 uniformly acts on the exhaust valve plate 3, and the stress condition of the exhaust valve plate 3 is improved.

As shown in fig. 2a, 2b and 3, in order to reliably fix the magnetic member 2 in the limiting groove 111, the limiting groove 111 is formed with a first limiting post 112 extending toward the exhaust valve plate 3, and correspondingly, the magnetic member 2 is formed with a first limiting hole 21; specifically, a first limiting hole 21 is formed at the bottom of the magnetic component 2, one end of the first limiting hole 21 is open, and the other end is closed; when the magnetic component 2 is embedded in the limit groove 111, the first limit column 112 is clamped in the first limit hole 21, and the first limit column 112 and the first limit hole 21 are in interference fit, so that the magnetic component 2 is fixedly connected with the lift limiter 11.
In other embodiments, the limiting groove 111 is formed with a second limiting hole extending in a direction away from the exhaust valve plate 3, and correspondingly, the magnetic component 2 is formed with a second limiting post; specifically, a second limit column is formed at the bottom of the magnetic component 2, and extends towards the lift limiter 11; when the magnetic component 2 is embedded in the limiting groove 111, the second limiting column is clamped in the second limiting hole, and the second limiting column and the second limiting hole are in interference fit, so that the magnetic component 2 is fixedly connected with the lift limiter 11.
Specifically, the limiting groove 111 is a cylindrical groove, and the outer diameter R1 satisfies the following conditions: r1 is more than or equal to 5mm and less than or equal to 7mm, and the depth H satisfies the following conditions: h is more than or equal to 2mm and less than or equal to 4 mm; the magnetic component 2 is of a cylindrical structure, and the outer diameter R2 meets the following requirements: r2 < R1.
The cylinder cover component also comprises a valve plate 4, and a vent hole 41 is formed on the valve plate 4 corresponding to the position of the vent valve plate 3; the exhaust valve plate 3 is arranged on one side of the valve plate 4 and used for opening or closing the exhaust hole 41; when the cylinder cover component exhausts, the higher exhaust pressure pushes the exhaust valve plate 3 open after passing through the exhaust hole 41; in a conventional cylinder head assembly, the exhaust valve plate 3 directly impacts the end surface of the lift limiter 11 to generate larger impact force, and larger noise is generated due to a discontinuous exhaust process; in addition, too large an impact force also causes fatigue of the discharge valve sheet 3, thereby lowering reliability.
In this embodiment, when the cylinder head assembly is about to start exhausting, the exhaust hole 41 is in a closed state, because a certain lift distance is provided between the exhaust valve plate 3 and the magnetic part 2, the repulsive force between the two is small, and resistance is not generated to the lifting of the exhaust valve plate 3; when the cylinder cover assembly exhausts, the exhaust valve plate 3 is pushed open by a larger exhaust pressure F1, the distance between the exhaust valve plate 3 and the magnetic part 2 is reduced along with the increase of the lifting height of the exhaust valve plate 3, the repulsive force F2 between the exhaust valve plate 3 and the magnetic part 2 is gradually increased, and when F2 is larger than F1, the exhaust valve plate 3 reaches the maximum limit height, so that the collision contact force between the exhaust valve plate 3 and the lift limiter 11 is greatly reduced; when the exhaust of the cylinder cover component is finished, the exhaust valve plate 3 gradually approaches the exhaust hole 41, and the repulsive force F2 between the exhaust valve plate 3 and the magnetic component 2 enables the exhaust valve plate 3 to respond quickly, so that the condition of refrigerant flow loss of the compressor caused by delayed closing of the exhaust hole 41 can be avoided, and the compressor is ensured to have better effect in high-frequency operation.
Preferably, when the exhaust pressure F1 and the repulsive force F2 between the exhaust valve plate 3 and the magnetic member 2 are almost equal, the exhaust valve plate 3 does not reach the maximum limit height, and the exhaust valve plate 3 is about to contact the lift limiter 11, so that the collision probability of the exhaust valve plate 3 and the lift limiter 11 is reduced, the noise of the compressor is greatly improved, and the reliability of the exhaust valve plate 3 is ensured.
It should be noted that the repulsive force between the air vent valve plate 3 and the magnetic member 2 can be designed according to actual needs; by reasonably designing the repulsive force, the noise between the exhaust valve plate 3 and the lift limiter 11 is favorably reduced, and the timely response of the exhaust valve plate 3 is favorably realized.
In other embodiments, the installation position is formed by the outer peripheral surface of the lift limiter 11, the magnetic component 2 is arranged on the outer peripheral surface of the lift limiter 11, the end surface of the lift limiter 11 protrudes out of the end surface of the magnetic component 2, the magnetic component 2 does not influence the lifting height of the exhaust valve plate 3, and the exhaust amount of the compressor is not changed; the magnetic component 2 can be one or more, and can be arranged according to actual needs.
Further, the magnetic component 2 is of an annular structure and is sleeved on the outer peripheral surface of the lift limiter 11, the inner peripheral surface of the magnetic component 2 and the outer peripheral surface of the lift limiter 11 are of matched structures, and the two are in interference fit; when the magnetic component 2 is sleeved on the outer periphery of the lift limiter 11, the magnetic component 2 is reliably connected with the lift limiter 11.
