Description
Technical field
The utility model relates to compressor field, particularly a kind of hermetically sealed compressor valve plate.
Background technique
Totally-enclosed compressor valve plate design mainly contains two kinds of flat valve plate and concave valve plates, in energy consumption, require more and more high today, compressor design is also considered exploitation efficient, energy-conserving product more, the compressor of originally common efficiency adopts the design of flat valve plate conventionally, and outlet valve is formed by riveted joint by exhaust valve plate, locating stud, outlet valve reed and exhaust limiting board; And the basic design that adopts concave valve plate of compressor valve design now partly forms an installation groove at outlet valve, reduce the thickness of exhaust port part to reduce the clearance volume of compressor.The design of concave valve plate outlet valve is generally comprised of exhaust valve plate, outlet valve reed and exhaust limiting board, different from flat valve plate, and spill air valve is without riveted joint, and it is fitted, compressed by valve plate face and cylinder head surface.Above-mentioned concave valve plate outlet valve is in assembly process, when placement exhaust valve plate enters mounting groove, may there is the problem of exhaust valve plate She Xingfa center and valve plate exhaust port decentraction, cause the sealing defective tightness of outlet valve to exhaust port, thereby affect the compression efficiency of compressor, reduced the performance of compressor.

Summary of the invention
For solving defect and the problem of conventional compressor valve board in prior art, the utility model provides a kind of compressor valve board reasonable in design, simple in structure, easy to use.
For solving the problems of the technologies described above the technical solution of the utility model, be: a kind of hermetically sealed compressor valve plate, comprise valve plate body, it is characterized in that: on described valve plate body, be provided with mounting hole, special-shaped mounting groove, exhaust port one, exhaust port two, baffler positioning hole, resonance lumen pore, suction port, described special-shaped mounting groove tail end is provided with restraining groove, the bottom of described special-shaped mounting groove afterbody is provided with valve seat planes, and described valve seat planes is extended and is provided with square platform in exhaust port one direction.
The degree of depth of described special-shaped mounting groove is 1/3～1/2 of valve plate body thickness.
The width of described restraining groove is that 0.5mm, length are 4.2mm.
Described valve seat planes is higher than special-shaped mounting groove base plane 0.15mm.
The length of described valve seat planes is 1/4 of special-shaped mounting groove length.
