Below embodiments of the invention being elaborated, the present embodiment is carried out under premised on technical solution of the present invention, gives detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
Embodiment 1
A kind of plane formula Snifter valve block of refrigerator compressor, including valve body 1 and tongue, valve body 1 is provided with tongue installing hole 2, it is characterized in that: valve body 1 and tongue are all in the form of sheets, tongue is arranged in tongue installing hole 2, and tongue includes spring plank 3 and spring tail 4, and spring tail 4 is in the banded structure of bending, one end of spring tail 4 connects spring plank 3, and the other end connects the inner edge of tongue installing hole 2. The tongue of existing Snifter valve block of refrigerator compressor is usually and is equivalent to cantilever beam structure, its in breathing process reed head tilt and tongue root also contacts with valve body 1, but require that when exhaust process tongue and valve plate want thorough seal, owing to tongue has warping phenomenon, thus can not be fully achieved seal request, this just makes cold-producing medium can produce leakage event, thus reducing the refrigerating efficiency of freezer compressor. Due to the restriction of tongue installing hole 2 size, the region that tongue provides deformation is limited, and so when reed head needs to upspring certain altitude, the degree of crook of deformed region is relatively big, thus causing the angle that reed head tilts big, affects sealing effectiveness. The present invention by being divided into spring plank 3 and spring tail 4 by tongue, and spring tail 4 is designed to the banded structure structure of bending, elongate the length of deformed region on tongue, when sustained height upspring by needs, the deformation extent of spring tail 4 is less, so that the angle that final spring plank 3 tilts diminishes, reduce the degree of its warpage, reach the effect that sealing promotes. The structure of banding can provide good elastic deformation space at above-below direction, certain rigidity can be kept in the horizontal direction, so ensure that spring plank 3 will not the skew in occurred level direction while moving up and down so that spring plank 3 can cover steam vent all the time, it is ensured that sealing.
