Abstract
The utility model discloses a suction valve plate structure used for a refrigeration compressor. The suction valve plate structure comprises a valve plate body, an outer spring plate, an air discharge hole, an installation hole, a throttling hole and an inner spring plate; the outer spring plate adopts a dual-arm spring plate structure; the inner spring plate is arranged inside the outer spring plate; and the air discharge hole is reserved on the inner spring plate. In the suction valve plate structure used for the refrigeration compressor, the maximal width size of a larger outer spring plate sealing area can be selected on the premise of not increasing motion energy consumption, so the effective flow area of a suction valve can be increased; and the improvement of the efficiency of the compressor is benefited.
Description
Technical field
The utility model relates to a kind of suction valve chip structure of refrigeration compressor.
Background technique
The suction valve chip structure of existing refrigeration compressor is provided with reed 1, exhaust port 2, mounting hole 3 and throttle orifice 4 as shown in Figure 1.Reed 1 adopts the single armed reed structure, has the function of sealing and bending motion, and the greatest width dimension of sealing area is D, and the minimum width dimension of bending area is d.Suction valve chip structure as shown in Figure 1 increases the valid circulation area that dimension D helps improving Aspirating valves, thereby improves gettering efficiency; And the selectable magnitude range of size d is less because the integrity problem of the too little meeting of size d when causing reed 1 bending motion, and size d too conference cause the energy consumption of reed 1 bending motion needs to increase, decrease in efficiency.Thereby, the shortcoming that existing suction valve chip structure shown in Figure 1 exists is: because the selectable magnitude range of minimum width dimension d of reed 1 bending area is less, can cause to increase the greatest width dimension D of reed 1 sealing area, because Billy factor D/d of dimension D and size d can not be too big, otherwise reed 1 is instability when bending motion, and gettering efficiency descends.
Summary of the invention
Technical problem to be solved in the utility model is to propose a kind of greatest width dimension that can increase the reed sealing area, to improve the gettering efficiency of compressor; Can guarantee that again the reed bending motion is in stable condition, and not increase the refrigeration compressor suction valve chip structure of sports energy consumption.
For solving the problems of the technologies described above, the utility model refrigeration compressor comprises valve block body, outer reed, exhaust port, mounting hole, throttle orifice and interior reed with the suction valve chip structure, described outer reed adopts the both arms reed structure, reed is located at the inboard of described outer reed in described, and described exhaust port is located on the described interior reed.
Above-mentioned refrigeration compressor suction valve chip structure, the greatest width dimension of the sealing area of described outer reed is greater than its height dimension.
Because the utility model refrigeration compressor adopted such scheme with the suction valve chip structure, when increasing the minimum width dimension d of outer reed bending area, need only the minimum dimension K1 and the K2 that control left and right sides both arms, the energy consumption of outer reed bending motion can not increase yet.Therefore, when the greatest width dimension D of the sealing area that increases outer reed according to the design needs, the minimum width dimension d of the bending area of the outer reed of corresponding increase obtains required Billy factor D/d, just can guarantee that outer reed bending motion is in stable condition.Because the utility model refrigeration compressor can be under the prerequisite that does not increase sports energy consumption with the suction valve chip structure, choose the greatest width dimension D of bigger outer reed sealing area, thereby can improve the valid circulation area of Aspirating valves, help compressor and raise the efficiency.
Description of drawings
Fig. 1 is the structural representation of existing refrigeration compressor with suction valve chip;
Fig. 2 is the structural representation of the utility model refrigeration compressor with suction valve chip;
Fig. 3 is the axonometric drawing with respect to Fig. 2.
Embodiment
As shown in Figures 2 and 3, the utility model refrigeration compressor comprises valve block body 6, outer reed 5, exhaust port 2, mounting hole 3, throttle orifice 4 and interior reed 9 with the suction valve chip structure, and outer reed 5 adopts the both arms reed structure, has the function of sealing and bending motion.The greatest width dimension of its sealing area is D, and height dimension is H, and dimension D is greater than size H; The minimum width dimension of bending area is d, and the minimum dimension of left and right sides both arms is respectively K1 and K2.On the reed 9, interior reed 9 did not have the function of sealing and bending motion in exhaust port 2 was located at.
When needs increased size d, as long as the minimum dimension K1 and the K2 of control left and right sides both arms, the energy consumption of outer reed 5 bending motions can not increase yet.Therefore, when increasing dimension D according to the design needs, corresponding increase size d obtains required Billy factor D/d, just can guarantee that outer reed 5 bending motions are in stable condition.Owing to can choose bigger dimension D, thereby the utility model refrigeration compressor under the prerequisite that does not increase sports energy consumption, can improve the valid circulation area of Aspirating valves with the suction valve chip structure, helps compressor and raises the efficiency.
