Description

Sectional type high-flatness valve group

Technical Field

The utility model relates to a compressor field especially relates to a sectional type high plane degree valves.

Background

The refrigerator compressor compresses gas in the cylinder, and the gas interaction is carried out outside the valve bank and the cylinder, so that a high-pressure cavity and a low-pressure cavity are formed inside and outside the cylinder, the two cavities are separated by a valve plate, and the on-off is controlled by a valve plate.

At present, the valve plate side of inhaling in the domestic refrigerator compressor valves mostly is a whole big plane and the laminating of suction valve piece, and suction valve piece reed just in time covers the valve plate induction port, and only when the compressor is breathed in, suction valve piece reed upwarps, and inside gaseous getting into the cylinder by the induction port, because reed opposite side laminating valve plate, the reed blocks the circulation of gas of induction port during the exhaust, and high-pressure gas is discharged by the gas vent. Under the normal condition, the joint condition of the air suction valve plate and the valve plate can directly influence the air suction and exhaust of the compressor, if impurities exist between the air suction valve plate and the valve plate, the air suction valve plate cannot be completely jointed with the valve plate, gas leakage can occur in the gas interaction process, the refrigerating capacity is reduced, and the working efficiency of the compressor is directly influenced; on the other hand, the valve plate of batch production can't guarantee that the big plane in suction side is complete flat in the course of working, and the plane is bigger, can't guarantee best plane degree more when grinding the plane, and to the valve plate that the plane degree is relatively poor, suction valve block also can't laminate with the valve plate betterly, still can cause gas leakage.
