Preferably, the efficient valve block of a kind of refrigerator compressor, described exhaust valve plate comprises front portion, middle part and end, described front portion is circular, be covered on the valve line place of valve plate, the end of described exhaust valve plate is provided with elastic lug, is provided with lug activity space between described elastic lug and exhaust valve plate.
Preferably, described exhaust valve plate width A is 3.35 ~ 3.50mm.
Preferably, the afterbody middle, end of described exhaust valve plate is provided with opening, and described opening is connected with lug activity space.
Preferably, described lug activity space is arc-shaped through-hole.
Preferably, the radian of described lug activity space is consistent with the linear radian in the bottom of end.
Preferably, described lug activity space is crescent shape through hole.
Preferably, described exhaust valve plate material is Hiflex steel.
Preferably, described exhaust valve plate material is Martensitic Stain Less Steel 7C27Mo2.
The beneficial effects of the utility model: by arranging elastic lug on exhaust valve plate, due to exhaust valve plate width A 0.03mm ~ 0.11mm more about than existing valve block size, easy to exhaust valve block is fixed in valve plate, and fix exhaust valve plate by elastic lug and lug activity space to have and assemble effect more closely, exhaust valve plate is made to be unlikely to upper and lower displacement in valve plate valve block groove excessive, and cause the stressed change of valve block to make the fatigue damages such as exhaust valve plate fractures, Main Function is: uniform force after (1) exhaust valve plate position is fixing, good airproof performance, noise is low; (2) exhaust valve plate operationally has high temperature, high pressure, and under having the environment of refrigeration agent, refrigerator oil, greatly can be improved the reliability of valve block, greatly reduce the situation losing efficacy and broke and occur, reduce valve block noise by the design of this structure and material.

Embodiment
In order to deepen understanding of the present utility model, below in conjunction with embodiment, the utility model is described in further detail, and this embodiment, only for explaining the utility model, does not form the restriction to the utility model protection domain.
Embodiment 1:
As shown in Figure 3 and Figure 4, present embodiments provide the efficient valve block of a kind of refrigerator compressor, the efficient valve block of a kind of refrigerator compressor, comprise valve plate 1 and exhaust valve plate 2, exhaust valve plate 2 comprises anterior 201, middle part 202 and end 203, this front portion 201 is designed to circle, be covered on the valve place of valve plate 1, the end of exhaust valve plate 2 is provided with elastic lug 3, and be provided with lug activity space 4 between elastic lug 3 and exhaust valve plate 2, valve block width same in prior art 0.03 ~ 0.11mm fewer than the wide A of the utility model valve block, utilize wider than prior art, when valve block is arranged in valve plate 1 groove, because B is wide, extruded by elastic lug 3 pairs of lug activity spaces 4, the resilience of lug activity space 4 energy, serve the effect of fixation valve block.
