Examples
The present embodiment provides a valve plate assembly.
Referring to fig. 1-7, the valve plate assembly includes a valve plate 100, a suction valve plate 200, a discharge valve plate 300, a suction valve member 400, and a discharge valve member 500.
Wherein the valve plate 100 has an intake port 110 and an exhaust port 120. The suction valve plate 200 and the discharge valve plate 300 are respectively provided on the front and rear surfaces of the valve plate 100 in correspondence with the covers. The suction valve member 400 and the exhaust valve member 500 are made of nonmetallic materials, and the suction valve member 400 and the exhaust valve member 500 are respectively embedded in the suction valve port 110 and the exhaust valve port 120.
In this way, since the suction valve member 400 and the discharge valve member 500 are made of non-metal materials and are respectively embedded in the suction valve port 110 and the discharge valve port 120 of the valve plate 100, the impact can be effectively relieved when the suction valve member 400 and the discharge valve member 300 are contacted with the discharge valve member 500 in the operation process of the compressor, and the noise is reduced.
In order to achieve a tight and reliable fitting of the suction valve member 400 and the discharge valve member 500, it may be performed by riveting, vulcanizing, or bonding.
In addition, compared with the prior art in which the suction valve line and the exhaust valve line are directly worn on the valve plate 100, the suction valve member 400 and the exhaust valve member 500 in the embodiment of the present invention can be understood as components independent of the valve plate 100, in other words, the suction valve member 400 and the exhaust valve member 500 can be made of nonmetallic materials by separate processing, which can certainly reduce the processing difficulty compared with the way of carrying out the wear on the powder metallurgy castings.
In order to ensure that the valve plate assembly can perform a good function during the refrigeration process during the operation of the valve plate assembly, the connection between the suction valve member 400 and the discharge valve member 500 and the valve plate 100 should be tight and reliable.
In contrast, referring to fig. 2-3, in the embodiment of the present invention, the inner wall of the exhaust valve port 120 extends to the inside of the exhaust valve port 120 to form a flange 121, the flange 121 encloses an exhaust port 1211, the flange 121 is located at the middle position of the exhaust valve port 120 in the thickness direction, and the flange 121 and the exhaust valve port 120 enclose a first receiving platform 122 located at the front surface of the valve plate 100 and a second receiving platform 123 located at the back surface of the valve plate 100.
Correspondingly, referring to fig. 4-5, the exhaust valve 500 includes a large-area plate 510, a small-area plate 520, and an invaginated plate 530 connected between the large-area plate 510 and the small-area plate 520, wherein the large-area plate 510, the small-area plate 520, and the invaginated plate 530 are correspondingly adapted to the second receiving platform 123, the first receiving platform 122, and the flange 121, respectively.
In this way, the flange 121, the first receiving platform 122, the second receiving platform 123, the large-area plate 510, the small-area plate 520 and the recessed plate 530 are arranged, so that the connection between the exhaust valve port 120 and the valve plate 100 becomes more complex, and the exhaust valve 500 and the valve plate 1000 can be tightly and reliably connected together after the exhaust valve 500 is mounted on the exhaust valve port 120.
Specifically, after the exhaust valve member 500 is mounted on the exhaust valve port 120 of the valve plate 100, the flange 121 is engaged with the outer periphery of the recess plate 530, the large-area plate 510 is embedded in the second receiving platform 123, the outer periphery of the large-area plate 510 abuts against the inner wall of the second receiving platform 123, the small-area plate 520 is embedded in the first receiving platform 122, and the outer periphery of the small-area plate 520 abuts against the inner wall of the first receiving platform 122, so that the tight and reliable connection between the exhaust valve member 500 and the valve plate 100 is ensured.
Further, the coverage area of the second receiving platform 123 is larger than that of the first receiving platform 122.
Thus, the exhaust valve member 500 can be installed at the exhaust valve port 120 up and down when the exhaust valve member 500 is actually installed, simplifying installation.
Specifically, since the external dimension of the small-area plate 520 is smaller than the external dimension of the large-area plate 510, in actual arrangement, the small-area plate 520 may be sized to be slightly larger than the inner diameter of the exhaust port 1211 surrounded by the flange 121, so that the small-area plate 520 may be inserted into the first receiving platform 122 through the exhaust port 1211.
At this point, it will be appreciated that the non-metallic material used to make the exhaust valve member 500 may be a soft material, such as rubber, so that the exhaust valve member 500 may be directly pressed from bottom to top into the exhaust port 120 when installed in accordance with the above-described procedure.
Referring to fig. 2-3 and fig. 6-7, suction valve port 110 has a third receiving platform 111 recessed from the front surface of valve plate 100, and suction port 1111 is provided on third receiving platform 111.
The suction port 1111 is formed in a communication path with the discharge port 1211, so as to function in the cooling operation of the compressor.
In order to ensure the tight and reliable connection between the suction valve 400 and the valve plate 100, a fastening hole 1112 penetrating the third receiving platform 111 is provided on the third receiving platform 111, the suction valve 400 includes a plate body 410 and a fastening post 420 extending downward from the lower surface of the plate body 410, the plate body 410 is adapted to be fitted on the third receiving platform 111, and the fastening post 420 penetrates through the fastening hole 1112 to fix the plate body 410 on the third receiving platform 111.
Similar to the foregoing, the plate body 410 and the fastening post 420 may be made of rubber or a non-metallic material similar to rubber, so that the mounting of the suction valve member 400 can be directly accomplished by pressing.
Further, the outer diameter of the fastening post 420 may be slightly larger than the inner diameter of the fastening hole 1112, so that after the installation, the fastening post 420 can be accommodated in the fastening hole 1112 in a contracted state, so as to further improve the connection tightness between the suction valve 400 and the valve plate 100.
In the embodiment of the present invention, the plurality of fastening ports 1112 are uniformly arranged on the third receiving platform 111, for example, in the example shown in fig. 2 to 3, four fastening ports 1112 are provided, and the four fastening ports 1112 are arranged in pairs at both ends in the length direction and the width direction of the third receiving platform 111.
Of course, in other embodiments, more fastening ports 1112 may be provided, and the arrangement of the fastening ports 1112 may be changed. For example, five fastening ports 1112 may be arranged, four of which are circumferentially arranged at the outer edge of the third receiving platform 111, and the other one at a central position of the third receiving platform 111.
In some embodiments, to prevent the suction valve 400 from being separated from the fastening hole 1112, a chuck 430 may be further disposed at the lower end of the fastening post 420, and the chuck 430 has a larger external dimension than the fastening post 420.
Thus, by the provision of the clip 430, the clip 430 can form a stopper structure with the plate body 410, which can restrict the position of the suction valve element 400 in the thickness direction, thereby preventing the suction valve element 400 from being detached from the fastening port 1112.
To secure the external appearance, the lower end of the fastening port 1112 is circumferentially expanded into a receiving portion 1113, and the chuck 430 is embedded in the receiving portion 1113.
Specifically, referring to fig. 7, the accommodating portion 1113 is located at the lower end of the fastening hole 1112, the accommodating portion 1113 is matched with the shape and size of the chuck 430, and the height of the accommodating portion 1113 is the same as the height of the chuck 430, so that when the chuck 430 is located in the accommodating portion 1113, the chuck 430 is flush with the back surface of the valve plate 100.
It should be noted that, the aforementioned exhaust valve element 500 should at least protrude from a portion of the exhaust valve port 120, and the suction valve element 400 should also at least protrude from a portion of the suction valve port 110, so that the exhaust valve element 300 can contact the exhaust valve element 500 and the suction valve element 200 can contact the suction valve element 400 when the valve plate assembly is in operation, thereby achieving the effect of reducing noise.
In particular to the exhaust valve member 500, the large-area plate 510 of the exhaust valve member 500 should protrude from the exhaust valve port 120, and the exhaust valve member 500 may be in contact with the exhaust valve sheet 300 at the back of the valve plate 100 through the large-area plate 510.
In particular to the suction valve member 400, the plate 410 of the suction valve member 400 should protrude from the suction valve port 110, and at this time, the suction valve member 400 may contact with the suction valve plate 200 located on the front surface of the valve plate 100 through the plate 410.

The compressor is provided with the valve plate assembly, so that noise can be effectively reduced when the compressor works.
The embodiment also provides a refrigerator, which comprises the compressor.
