Abstract

The invention provides a check valve, a scroll compressor and an air conditioner. The check valve comprises a valve seat, a valve plate, a baffle and a fastener. The valve seat is mounted in a compressor enthalpy increase and gas supplementation channel, and a valve hole is formed in the valve seat. The valve plate is arranged in the valve hole. The baffle is arranged on the side face, away from the valve hole, of the valve plate and is used for limiting the valve plate. The fastener fixes the baffle and the valve plate to the valve seat. The check valve is simple in structure, convenient to produce and machine, low in cost and small in size, can be conveniently arranged in an enthalpy increase channel of a fixed scroll plate of the scroll compressor and is close to a gas supplementation and enthalpy increase compression cavity, non-return responses are fast, the non-return effect is good, meanwhile, the clearance volume in a non-return passageway is small, thermal expansion of a high-pressure refrigerant in an enthalpy increase pipeline can be effectively reduced, and the energy efficiency of the compressor is improved.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to a check valve, a scroll compressor and an air conditioner. Background technique [0002] The vortex enthalpy increasing technology introduces the low-temperature and low-pressure refrigerant in the flasher or economizer directly into the compression chamber under compression. A one-way check valve is provided, but the existing check valve is complicated, and an additional structure needs to be added to the compressor structure, resulting in a complicated compressor structure, larger size and weight. Contents of the invention [0003] Therefore, the technical problem to be solved by the present invention is that the structure of the existing check structure is complex, and an additional structure needs to be added, resulting in a complex structure of the compressor, larger size and weight, thereby providing a check valve, scroll compressor machines and air condi...
