The invention relates to a suction and exhaust valve, a heat pump reverse rotor type compression device and an air conditioning system. The suction and exhaust valve comprises a valve seat, a valve element assembly and at least one elastic piece, wherein the valve seat is provided with a high-pressure gas storage groove and a valve element mounting hole; the valve element assembly is mounted at the valve element mounting hole; and the elastic piece is connected with the valve seat and used for deforming when gas with preset pressure intensity is introduced into the high-pressure gas storage groove, and then the valve seat is driven to move. High-pressure gas exhausted by a compressor acts on the high-pressure gas storage groove of the suction and exhaust valve in a corresponding suction and exhaust port to enable the elastic piece to deform, the valve seat is driven to move till a valve element of the suction and exhaust valve seals the corresponding suction and exhaust port, the valveseat can be matched with the corresponding suction and exhaust port through the high-pressure gas storage groove of the valve seat to form a high-pressure gas sealing cavity, the high-pressure gas flows into the high-pressure gas sealing cavity and does not leak, then the pressure can be rapidly increased to the pressure capable of effectively driving the elastic piece to deform, and the valve element can completely seal the suction and exhaust port.
Description
technical field [0001] The invention relates to the technical field of refrigeration, in particular to a suction and discharge valve, a heat pump reverse rotor type compression device and an air conditioning system. Background technique [0002] Rotary compressors are widely used in air conditioning systems due to their low noise, no need for suction and discharge valves, high efficiency, small size and light weight. At present, in order to realize the conversion between cooling in summer and heating in winter, and without installing a four-way valve on the air conditioning system, the rotary compressor is generally set as a reverse rotary compressor, that is, the compressor can perform forward and reverse rotation. To realize the conversion of cooling and heating. Among them, the reverse rotor compressor is equipped with suction and exhaust valves at the two suction and exhaust ports of its own cylinder, and the spool of the suction and discharge valve can be pushed up und...
