Problems solved by technology

[0004] The purpose of the present invention is to provide a convenient and durable refrigerator compressor valve plate, which is used to fix the valve plate by installing elastic lugs at the root of the valve plate, and uses Hiflex steel to make the valve plate to prevent the valve plate from being too large due to misalignment Causes the valve plate to break, which solves the problems that the valve plate is easy to break, the valve plate is not well sealed and the noise is too loud

Embodiment 1

[0027] like image 3 and Figure 4 As shown, this embodiment provides a high-efficiency valve plate of a refrigerator compressor, a high-efficiency valve plate of a refrigerator compressor, including a valve plate 1 and an exhaust valve plate 2, and the exhaust valve plate 2 includes a front part 201, a middle part 202 and end 203, the front part 201 is designed as a circle, covering the valve of the valve plate 1, the end of the exhaust valve plate 2 is provided with an elastic lug 3, and the elastic lug 3 and the exhaust valve plate 2 is provided with a protruding activity space 4, the width of the same valve plate in the prior art is 0.03~0.11mm less than the width A of the valve plate of the present invention, and the utilization is wider than the prior art, when the valve plate is installed in the groove of the valve plate 1 Inside, due to the width of B, the elastic lug 3 squeezes the lug movable space 4, and the lug movable space 4 can rebound, which plays the role of ...

Embodiment 2

[0031] like Image 6 and Figure 7 As shown, the rest are the same as in Embodiment 1, the difference is that the front of the end is the first straight line segment 2031, the first arc line segment 2032, the connecting direct line segment 2033, the connecting arc line segment 2034, and the second straight line segment 2035, the second arc line segment 2036, the third straight line segment 2037, and the third arc line segment 2038. This plane view is also a closed geometric shape, and the third arc line segment 2038 is connected to the first straight line segment 2031, wherein the first straight line segment 2031 and the second straight line 2035 are horizontal, the connecting straight line 2033 and the third straight line 2037 are vertical, and the activity space 4 of the lug is still linearly consistent with the bottom of the end, and the exhaust valve piece 2 is made of martensitic stainless steel 7C27Mo2 .

Embodiment 3

[0033] like Figure 8 As shown, the rest is the same as that of Embodiment 1, the difference is that an opening 5 is provided in the middle of the end 203 tail of the exhaust valve plate 2, and the opening 5 communicates with the tab movable space 4, which not only saves exhaust gas The material of the valve plate 2 simultaneously acts as a double assembly and fixing function through the structural combination of the elastic lug 3 and the opening 5 .

Abstract

The invention relates to the field of refrigerator or freezer compressors and provides a high-efficiency valve block for the refrigerator or freezer compressor. The high-efficiency valve block comprises a valve plate and an exhaust valve block, wherein the exhaust valve block comprises a front part, a middle part and an end part; the front part is circular and covers a valve line of the valve plate; an elastic lug is arranged at the end part of the exhaust valve block; a lug moving space is arranged between the elastic lug and the exhaust valve block. The elastic lug is arranged on the exhaust valve block, so that the exhaust valve plate is conveniently fixed in the valve plate; in addition, the exhaust valve block is fixed by the elastic lug and the lug moving space, so the more tight assembly effect is realized, and the phenomenon that the exhaust valve block is broken and generates other fatigue loss and noises due to the fact that the stress of the exhaust valve block is changed caused by overlarge vertical displacement of the exhaust valve block in a valve block groove of the valve plate is avoided.

Description

technical field [0001] The invention relates to the field of refrigerator compressors, in particular to a refrigerator and freezer compressor valve plate with high reliability and good sealing performance. Background technique [0002] The valve plate on the refrigerator freezer compressor is one of the very important components. An exhaust valve is installed on the valve plate, and the exhaust valve seals the exhaust hole. When the pressure in the cylinder hole of the compressor cylinder seat is greater than the pressure on the side where the exhaust valve is installed, the exhaust valve is opened, and the refrigerant is pumped by the piston. After being compressed, it passes through the exhaust hole of the valve plate and then goes through the two-stage muffler to the condenser of the refrigeration system. Because the exhaust valve plate needs to be opened, closed and reset at least 2920 times per minute, the existing valve plate is in the installation process due to the ...
