Abstract
The utility model relates to a high-efficiency suction valve plate of a refrigeration compressor. The suction valve plate comprises a valve plate body (1), wherein a tongue-shaped valve plate (2) and a mounting hole (3) fixed with a cylinder are arranged on the valve plate body (1); a first exhaust vent (4) communicated with a high pressure chamber of a cylinder base and a second exhaust vent (5) communicated with a resonant chamber of the cylinder base are further arranged on the valve plate body (1); the head of tongue-shaped valve plate (2) is an elliptical structure, a middle transitional portion of the tongue-shaped valve plate (2) is a wasp-waisted structure on which a third exhaust vent (6) is formed. According to the suction valve plate disclosed by the utility model, suction holes and exhaust vents on the tongue-shaped valve plate are designed on the same axial line, a waist portion of the tongue-shaped valve plate is made as the wasp-waisted structure, so that an opening area of the suction holes is effectively enlarged; meanwhile, a clearance between the tongue-shaped valve plate and the suction valve plate body is changed, by doing this, a refrigerating capacity of the compressor is effectively increased, fluid resistance loss of the refrigeration compressor is reduced, a coefficient of performance (COP) of the refrigeration compressor is increased by at least 4%; therefore, the suction valve plate has a wide market prospect.
Description
Technical field
The utility model relates to refrigeration compressor Component field, especially a kind of suction valve chip of high efficiency refrigeration compressor.
Background technique
The suction valve chip ligulate valve block of existing refrigeration compressor is all to have a certain degree (angle A is less than 90 degree) with axis as shown in Figure 1, although this has facilitated the distribution of the air-breathing and exhaust port of cylinder valve plate mechanism, but in the situation that cylinder diameter is certain, larger due to what intakeport cannot be done, the working efficiency of cylinder can not be improved.
Summary of the invention
The utility model mainly solves the not high technical problem of existing suction valve chip gettering efficiency, provide a kind of simple in structure, can effectively strengthen the area of the suction port of refrigeration compressor, improve refrigeration compressor gas transmission coefficient, promote the suction valve chip of the coefficient of performance of compressor.
For solving the problems of the technologies described above the technical solution of the utility model be: a kind of suction valve chip of high efficiency refrigeration compressor, comprise valve block body, on described valve block body, be provided with ligulate valve block and with the fixing mounting hole of cylinder, it is characterized in that: on described valve block body, be also provided with the exhaust port one that is communicated with cylinder seat hyperbaric chamber and the exhaust port two that is communicated with cylinder seat resonant cavity, described flap valve sheet head is oval structure, middle transition position is eel-like figure structure, and is provided with exhaust port three at eel-like figure position.
Described ligulate valve block is that vertical water horizontal line is arranged.
Described exhaust port three edges are 1-1.5mm from the distance at the eel-like figure edge of ligulate valve block.
Gap between described ligulate valve block and valve block body is 0.1mm.
The utlity model has following technique effect: by by the suction port on ligulate valve block, vent design on same axis, and its waist is made to eel-like figure structure, can effectively strengthen the open area of suction port, 0.1mm is accomplished to by existing 0.4mm in gap between ligulate valve block and suction valve chip body simultaneously, can effectively promote on the one hand the refrigerating capacity of compressor, unlatching that on the other hand can more convenient ligulate valve block, reduce refrigeration compressor fluid impedance losses, promote the coefficient of performance (COP) of refrigeration compressor more than 4%.
Brief description of the drawings
Fig. 1 is the structural representation of compressor air suction valve block in prior art;
Fig. 2 is the structural representation of the utility model compressor air suction valve block.
Specific embodiment
Below in conjunction with accompanying drawing 2 and embodiment, the utility model is described in further detail:
A kind of suction valve chip of high efficiency refrigeration compressor, comprise valve block body 1, on described valve block body 1, be provided with ligulate valve block 2 and with the fixing mounting hole 3 of cylinder, it is characterized in that: on described valve block body 1, be also provided with the exhaust port 1 that is communicated with cylinder seat hyperbaric chamber and the exhaust port 25 that is communicated with cylinder seat resonant cavity, described ligulate valve block 2 heads are oval structure, middle transition position is eel-like figure structure, and is provided with exhaust port 36 at eel-like figure position.
Described ligulate valve block 2 is vertical water horizontal line layout.
Described exhaust port 36 edges are 1.2mm from the distance at the eel-like figure edge of ligulate valve block 2.
Gap between described ligulate valve block 2 and valve block body 1 is 0.1mm.
The above; it is only preferably embodiment of the utility model; but the utility model protection domain is not limited to this, is equal to replacement or is changed according to the technical solution of the utility model and inventive concept thereof, within all should being encompassed in protection domain of the present utility model.
