Background technique
Refrigeration compressor by suction and discharge Period Process alternately realize the supply of refrigerant to refrigeration system.Air-breathing and exhaust process is all the process of refrigerant one-way flow, and in the time that piston moves toward lower dead centre, volume of cylinder increases, gas expansion, and air pressure reduces, and in the time that pressure is brought down below pressure of inspiration(Pi), suction valve chip is opened, and the refrigerant of low voltage side enters cylinder; In the time that piston moves toward upper dead center, volume of cylinder reduces, and gas is compressed, and air pressure raises, and when pressure rise is when higher than exhaust pressure, exhaust valve plate is opened, and in cylinder, refrigerant is discharged.Thereby suction and the discharge characteristic of the performance of suction and discharge valve block to refrigerant plays a part very crucial.
Existing refrigeration compressor adopts Reed Valve structure as shown in Figure 1 mostly with suction valve chip, is made up of valve block supporting zone 1 and Reed Valve 2, and the tail end 21 of Reed Valve 2 is fixed end, and intermediate section 22 is high bending area, and front end 23 is circular arc region.As shown in Figure 2, a side of suction valve chip is connected with the cylinder 6 of compressor by pad 5, and opposite side is connected with valve plate 4, and the tail end 21 of Reed Valve 2 is compacted.When Reed Valve 2 is during in closed condition, circular arc region 23 covers the suction port 3 on valve plate 4, plays seal action.As shown in Figure 3, in the time that Reed Valve 2 is opened, its variant is similar to overhang.Arrive lift process from just starting to be opened into, the Lift of whole valve block presents the variation of continuous increase from fixed end 21 to circular arc region 23.Therefore, in whole opening process, less near the part Lift of fixed end 21, the circulation of refrigerant has been produced to larger flow resistance, waste part circulation area, reduce effective intake of refrigerant, reduce the gettering efficiency of refrigeration compressor.
Summary of the invention
Technical problem to be solved by this invention is to propose one can effectively increase refrigerant intake to promote refrigeration compressor performance, and by improving the stress distribution of valve block with the refrigeration compressor suction valve chip of raising valve block life and reliability.
For solving the problems of the technologies described above, a kind of refrigeration compressor of the present invention comprises valve block supporting zone and suction reed with suction valve chip, described valve block supporting zone is provided with exhaust port, described suction reed is connected with described valve block supporting zone by two or more arms that flexibly connect, described in to flexibly connect arm symmetrical or be distributed in equably described suction reed around.
Above-mentioned a kind of refrigeration compressor suction valve chip, it also includes clearance filler piece, and described clearance filler piece flexibly connects between arm and suction reed described in being located at respectively, and the root of described each clearance filler piece is connected with described valve block supporting zone.
Above-mentioned a kind of refrigeration compressor suction valve chip, described suction reed be shaped as circle.
Above-mentioned a kind of refrigeration compressor suction valve chip, the two ends of described suction reed flexibly connect arm and described integrated being connected of valve block supporting zone by one respectively, and described two flexibly connect arm and are symmetric about the geometrical center of described suction reed.
Above-mentioned a kind of refrigeration compressor suction valve chip, described clearance filler piece has two, described each clearance filler piece flexibly connects between arm and described suction reed described in being located at respectively one, the root of described each clearance filler piece is connected with described valve block supporting zone, and described two clearance filler pieces are symmetrical about the geometrical center of described suction reed.
Above-mentioned a kind of refrigeration compressor suction valve chip, described in flexibly connect arm and adopt rounding off, bandy curve shape.
Above-mentioned a kind of refrigeration compressor suction valve chip, described in flexibly connect arm and described valve block supporting zone joint adopt bandy shape.
The present invention is owing to having adopted above-mentioned technical pattern, it has improved linkage structure between suction reed and valve block supporting zone and the opening ways of suction reed, there is following significant beneficial effect: 1, flexibly connect arm and be symmetry or equal distribution about suction reed geometrical center, every link arm is made up of rounding off curve, in the time that valve block is opened, flexibly connecting arm is stretched, along the circumferential direction Lift is consistent to make suction reed, present translation opening ways, thereby can make full use of the space that valve block unlatching forms, reduce the resistance of refrigerant circulation, effectively increase the intake of refrigerant, promote gettering efficiency, and then the performance of lifting refrigeration compressor, 2, flexibly connecting arranging of arm can be for suction valve chip provides rational rigidity and frequency, thereby controls the opening and closing time of valve block, effectively avoids the backflow of refrigerant, 3, flexibly connecting arm and suction reed zone line is distributed with clearance filler piece, clearance filler piece, about suction reed geometrical center symmetry or equal distribution, ensureing that valve block meets under the prerequisite of rigidity requirement, can effectively reduce clearance volume, has improved exhaust rate, 4, flexibly connect arm and adopt outwardly-bent structure, reasonable in design, has improved the stress distribution of flexible arm root effectively, has promoted the life and reliability of valve block.
