Abstract
The utility model relates to an exhaust reed valve used in the 2FL5BA semi-closed refrigeration piston-shaped compressor, comprising a valve plate, positioning pins, valve pieces, a lifting process limiting device, a lock piece, and screws. A buffer piece and spring pieces of the homogeneous machines are not needed in the utility model. Because the dimensions of the valve pieces of the exhaust reed valve of the utility model are appropriate, the valve pieces have good law of movement with small flow resistance and big refrigerating capacity. Meanwhile, because the exhaust reed valve has simple structure and less parts, the utility model has low cost and good structure technology.
Description
Affiliated technical field, refrigeration technology
Air valve is one of vitals of Piston Refrigerant Compreessor, and its performance directly has influence on the refrigeration compressor Economy and the reliability in when running, if design unreasonablely, the undesired motion that can produce valve block reduces the refrigerating capacity of compressor, and the life-span descends.
2FL5BA type semi-hermetic piston-type refrigeration compressor is the new product that China is developing, and is one of emphasis of development to the exhaust Reed Valve of this compressor.
By U.S. Copeland company and in West Germany, the similar semi-hermetic piston-type refrigeration compressor that English gall nut company produces, its exhaust Reed Valve is made up of valve plate, positioning dowel, valve block, buffer substrate tablet, spring sheet, lift limiter, locking plate, screw.According to our research, prove this exhaust Reed Valve complete opening at low temperatures, thereby flow resistance big, influence refrigerating capacity.
In addition, because the exhaust Reed Valve part of Copeland company is more, and spring sheet, buffer substrate tablet also needs heat treatment, increases process complexity and cost.
Fig. 1 is an exhaust Reed Valve of the present utility model.(1) be that valve plate, (2) are positioning dowel for locking plate, (5) for screw, (6) for lift limiter, (4) for valve block, (3), this exhaust Reed Valve does not have buffer substrate tablet and spring sheet.Therefore, simple in structure.
The diameter of valve plate (1) upper air-vent (seeing A place among Fig. 1) is in 10 to 12 millimeters scopes, and valve plate (1) thickness is in 7 to 9 millimeters scopes, and valve block (2) width (seeing H among Fig. 3) is in 17 millimeters to 19 millimeters scopes; Valve block (2) thickness is in 0.32 millimeter to 0.45 millimeter scope.Lift limiter (3) makes height restriction (see figure 1) in 2 millimeters to 3 millimeters scopes of the lift h of valve block (2).Lift limiter (3) width and valve block (2) width equate or lift limiter (3) width is a bit larger tham 1 to 2 millimeter of valve block (2) width; Valve (2) material is Sweden's valve block steel, after heat treatment hardness be HV377 to HV620, the optimum value of a part of size is in the above-mentioned parameter: valve plate (1) upper air-vent A diameter is 11 millimeters; Valve block (2) thickness is 0.35 millimeter; Lift h is 2.5 millimeters.
Because exhaust Reed Valve of the present utility model has only a slice valve block, cancelled buffer substrate tablet and spring sheet, and the valve block size is suitable, makes valve block that the good characteristics of motion be arranged, flow resistance is little, and refrigerating capacity is big.Simultaneously, simple in structure because of this air valve, part is few, so cost is low, good manufacturability helps processing.
One of important indicator of weighing air valve performance quality is the characteristics of motion of valve block.Fig. 2 is the valve plate movement law curve that the utility model exhaust Reed Valve records.Show that valve block moves well in opening process.
Another important indicator of weighing air valve performance quality is the Ke value that is used to judge the refrigerant compression engine efficiency.Through actual measurement, behind the utility model exhaust Reed Valve, the Ke value has surpassed 7% of Copeland company like product under standard condition.
