The utility model discloses the accuracy is fixed a position with the exhaust piece to the piece of breathing in in the structure, and the volume is less, and the assembly is simple and easy, has not only reduced manufacturing cost, has improved assembly efficiency moreover.
Description
Technical field
The utility model relates to the cylinder head valve lens of compressor for refrigerator, specifically a kind of suction, outlet valve plate structure being assemblied in the compressor for refrigeration of cylinder head.
Background technique
Compressor for refrigeration generally adopts reciprocating piston structure, motor is moved reciprocatingly in cylinder by connecting rod driven plunger, thus make gas in cylinder form the thermodynamic cycle of air-breathing, compression, exhaust and expansion, and by the suction system in cylinder head valve lens and vent systems, while reciprocating motion of the pistons, realize the effect of air-breathing and exhaust respectively.In air-breathing and exhaust process, the assembly of most critical is exactly by the assembly of inspiration piece, exhaust sheet and valve plate matched together.When compressor moves reciprocatingly by inhaling, exhaust sheet in turn opening and closing to realize the thermodynamic cycle of air-breathing, compression, exhaust and expansion.Shown in Fig. 1 is existing suction, the structure being vented valve plate, comprises the groove valve plate 1 with suction port and exhaust port, and respectively there are inspiration piece 2 and exhaust sheet 3 in the two sides of groove valve plate 1, is cut out the shape of specifying profile valve block by clicking technique.Usually exhaust sheet 3 is cut into the structure only having exhaust events sheet, then exhaust sheet 3 is arranged in valve plate groove 1, then fixes with the snubber be arranged in groove.But because inspiration piece 2 is monolithic structure, cost compare is high; And it is many to be vented part comparison when sheet 3 is installed, installation requirement is higher.
Summary of the invention
Technical problem to be solved in the utility model is to propose a kind of inspiration piece and exhaust sheet area is little, it is simple and easy to assemble, the air inlet-exhaust valve plate structure of the compressor for refrigeration of accurate positioning.
For solving the problems of the technologies described above, the air inlet-exhaust valve plate structure of a kind of compressor for refrigeration of the utility model comprises valve plate, inspiration piece and exhaust sheet, described valve plate is provided with suction port and exhaust port, the suction side of described valve plate and exhaust side are respectively equipped with for fixing described inspiration piece and two counterbores being vented sheet, the fixed end of described inspiration piece is provided with two positioning through hole, pin is through after two positioning through hole of described inspiration piece, insert in the described counterbore of described valve plate suction side, and form interference fit with the described counterbore in described valve plate suction side, described inspiration piece is fixedly connected on described valve plate, the fixed end of described exhaust sheet is provided with two location through holes, pin is through after two location through holes of described exhaust sheet, insert in the described counterbore of described valve plate exhaust side, and form interference fit with the described counterbore on described valve plate exhaust side, described exhaust sheet is fixedly connected on described valve plate.
The air inlet-exhaust valve plate structure of above-mentioned a kind of compressor for refrigeration, described exhaust sheet is L shape, and one end of its shortwall is its fixed end.
The air inlet-exhaust valve plate structure of above-mentioned a kind of compressor for refrigeration, on described valve plate, the diameter of set counterbore is less than the diameter of described pin, and on described valve plate, the degree of depth of set counterbore is greater than the length of described pin straightway.
The air inlet-exhaust valve plate structure of above-mentioned a kind of compressor for refrigeration, on described inspiration piece, on set positioning through hole and described exhaust sheet, the diameter of set location through hole is greater than the diameter of set counterbore on the diameter of described pin straightway and described valve plate respectively.
The utility model is owing to have employed technique scheme, and inspiration piece and exhaust sheet can accurately be located, and realize the opening and closing action in compressor function, and volume are little, can reduce cost of material.Meanwhile, the assembling of exhaust sheet does not need by snubber, improves efficiency of assembling, reduces cost of production.The utility model can be widely used in the valve board assembly in refrigerator compression.
Accompanying drawing explanation
Fig. 1 is the assembly structure schematic diagram of existing inspiration piece, exhaust sheet and valve plate;
Fig. 2 is the structural representation being provided with inspiration piece side in the utility model air inlet-exhaust valve plate structure;
Fig. 3 is the structural representation being provided with exhaust sheet side in the utility model air inlet-exhaust valve plate structure.
Embodiment
As shown in Figures 2 and 3, the air inlet-exhaust valve plate structure of the utility model compressor for refrigeration comprises valve plate 1, inspiration piece 2 and exhaust sheet 3.Valve plate 1 is provided with suction port and exhaust port, and inspiration piece 2 is fitted in the suction port side of valve plate 1, and exhaust sheet 3 is fitted in the exhaust port side of valve plate 1.The suction port side of valve plate 1 and exhaust port side are respectively equipped with for fixing inspiration piece 2 and two counterbores being vented sheet 3.
As shown in Figure 2, one end of inspiration piece 2 is its fixed end, which is provided with two positioning through hole, pin 4 is through after these two positioning through hole, insert in the counterbore set by valve plate 1 suction side, and with set counterbore interference fit in valve plate 1 suction side, inspiration piece 2 is fixedly connected on valve plate 1.In valve plate 1 suction side, the diameter of counterbore is less than the diameter of pin 4, and the counterbore degree of depth is greater than the length of pin 4 straightway.The diameter of two positioning through hole is greater than the diameter of counterbore in the diameter of pin 4 straightway and valve plate 1 suction side.
As shown in Figure 3, exhaust sheet 3 is L shape, one end of its shortwall is its fixed end, which is provided with two location through holes, pin 4 is through these two location through holes, insert in the counterbore set by valve plate 1 exhaust side, and with set counterbore interference fit on valve plate 1 exhaust side, exhaust sheet 3 is fixedly connected on valve plate 1.On valve plate 1 exhaust side, the diameter of counterbore is less than the diameter of pin 4, and the counterbore degree of depth is greater than the length of pin 4 straightway.The diameter of two location through holes is greater than the diameter of counterbore on the diameter of pin 4 straightway and valve plate 1 exhaust side.
