Abstract
The invention discloses an air suction valve sheet structure for a refrigeration compressor. The structure comprises a valve sheet body, an external reed, an exhaust hole, an installation hole, a throttle hole and an internal reed, wherein the external reed has a two-arm reed structure; the internal reed is arranged on the inner side of the external reed; and the exhaust hole is formed on the internal reed. In the air suction valve sheet structure for the refrigeration compressor, the maximum width size of a sealing area of the larger external reed can be selected on the premise of not increasing motion energy consumption so as to improve the effective circulation area of an air suction valve and contribute to improving the efficiency of the compressor.
Description
Technical field
The present invention relates to a kind of absorption valve plate structure of refrigeration compressor.
Background technique
The absorption valve plate structure of existing refrigeration compressor as shown in Figure 1, is provided with reed 1, exhaust port 2, mounting hole 3 and throttle orifice 4.Reed 1 adopts single armed reed structure, and have the function of sealing and bending motion, the greatest width dimension of sealing area is D, and the minimum width dimension of bending area is d.Absorption valve plate structure as shown in Figure 1, increases the valid circulation area that dimension D is conducive to improving Aspirating valves, thus improves gettering efficiency; And the selectable magnitude range of size d is less, because integrity problem when the too little meeting of size d causes reed 1 bending motion, and size d too conference cause the energy consumption of reed 1 bending motion needs to increase, decrease in efficiency.Thus, the shortcoming that existing absorption valve plate structure shown in Fig. 1 exists is: because the selectable magnitude range of minimum width dimension d of reed 1 bending area is less, the greatest width dimension D that can not increase reed 1 sealing area can be caused, because the Billy factor D/d of dimension D and size d can not be too large, otherwise reed 1 is unstable when bending motion, gettering efficiency declines.
Summary of the invention
Technical problem to be solved by this invention is to propose a kind of greatest width dimension that can increase reed sealing area, to improve the gettering efficiency of compressor; Can ensure that again reed bending motion is in stable condition, and not increase the air suction valve sheet structure for refrigeration compressor of sports energy consumption.
For solving the problems of the technologies described above, air suction valve sheet structure for refrigeration compressor of the present invention comprises valve block body, outer reed, exhaust port, mounting hole, throttle orifice and interior reed, described outer reed adopts both arms reed structure, the inner side of described outer reed is located at by described interior reed, and described exhaust port is located on described interior reed.
Above-mentioned air suction valve sheet structure for refrigeration compressor, the greatest width dimension of the sealing area of described outer reed is greater than its height dimension.
Because air suction valve sheet structure for refrigeration compressor of the present invention have employed such scheme, when increasing the minimum width dimension d of outer reed bending area, as long as control minimum dimension K1 and the K2 of left and right both arms, the energy consumption of outer reed bending motion also can not increase.Therefore, when needing the greatest width dimension D of the sealing area increasing outer reed according to design, the minimum width dimension d of the bending area of the outer reed of corresponding increase, the Billy factor D/d needed for acquisition, just can ensure that outer reed bending motion is in stable condition.Because air suction valve sheet structure for refrigeration compressor of the present invention under the prerequisite not increasing sports energy consumption, can be chosen the greatest width dimension D of larger outer reed sealing area, thus can improve the valid circulation area of Aspirating valves, be conducive to compressor and raise the efficiency.

Fig. 1 is the structural representation of existing refrigeration compressor suction valve chip;
Fig. 2 is the structural representation of refrigeration compressor suction valve chip of the present invention;
Fig. 3 is the axonometric drawing relative to Fig. 2.
Embodiment
As shown in Figures 2 and 3, air suction valve sheet structure for refrigeration compressor of the present invention comprises valve block body 6, outer reed 5, exhaust port 2, mounting hole 3, throttle orifice 4 and interior reed 9, and outer reed 5 adopts 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 both arms is respectively K1 and K2.Exhaust port 2 is located on interior reed 9, and interior reed 9 does not have the function of sealing and bending motion.When needs increase size d, as long as control minimum dimension K1 and the K2 of left and right both arms, the energy consumption of outer reed 5 bending motion also can not increase.Therefore, when needing to increase dimension D according to design, corresponding increase size d, the Billy factor D/d needed for acquisition, just can ensure that outer reed 5 bending motion is in stable condition.Due to larger dimension D can be chosen, thus, air suction valve sheet structure for refrigeration compressor of the present invention, under the prerequisite not increasing sports energy consumption, can improve the valid circulation area of Aspirating valves, is conducive to compressor and raises the efficiency.
