Preferably, the other end of described valve block snaps in the clamping part of restraining groove side.
Preferably, described clamping part part restraining groove that is protruding by the screens be arranged in restraining groove and the protruding right-hand member of screens forms.
Preferably, described limiting board press against the first shell fragment by the projection that its underpart is arranged.
Preferably, described first shell fragment snaps in the clamping part of restraining groove side.
Preferably, described spring sheet also has the 3rd shell fragment, and the 3rd shell fragment and the symmetrical inclination of the first shell fragment are connected to the other end of the second shell fragment, and the 3rd shell fragment is tilted to down relative to the second shell fragment.
Preferably, be provided with arc boss in described restraining groove, the 3rd shell fragment is pressed on arc boss; Described limiting board press against the seamed edge that the second shell fragment is connected with the 3rd shell fragment.
The beneficial effects of the utility model are:
Valve block structure in this practical property refrigeration compressor mechanical part, by valve block structure and the supporting combination of compressor, valve block structure is novel, adopt the supporting combination of valve block, spring sheet and limiting board to the limit method of valve seat, valve block, spring sheet and limiting board are arranged in spacing hole, retain certain interval between restraining groove lower end surface and valve block, ensure to assemble flexibly simultaneously, carry out spacing fully to the non-opening and closing direction of valve block, when to valve block, spring sheet, when limiting board and valve seat are assembled, elastic conjunction between restraining groove and limiting board, ensure that tension force when limiting board is assembled, limiting board carries out elastic compression to spring sheet simultaneously, spring sheet compresses valve block, when the rising thrust being subject to gas in valve opening makes valve block self open or closes, valve block upper end contacts with spring sheet, valve block by the stress dispersion that is subject to gas in valve opening to reed and valve block everywhere, avoid the phenomenon of the concentrated stress occurred when existing valve block directly contacts with limiting board, also the situation that limiting board damages just is decreased, this valve block, the usage mode of spring sheet and the supporting combination of limiting board for valve group reliability and the lifting in working life more obvious.
