The invention provides expansion valve components, a one-way expansion valve and a two-way circulation expansion valve, belonging to the technical field of refrigeration of variable frequency air conditioners. The invention solves the problem that the service life of a valve is shortened due to frequent abrasion of the conventional valve cores and the conventional vale bases. The two-way circulation expansion valve comprises a valve block which is provided with two parallel channels, wherein each channel is provided with an inlet end and an outlet end; an expansion valve component which is provided with a damping structure is connected to each outlet end; a bypass hole for communicating an outlet of the expansion valve component on one channel with the inlet end of the other channel is formed in the valve block; and a protection cover for preventing a medium from being leaked when flowing through the bypass hole and the outlet is welded at each outlet end. The two expansion valve components are arranged in parallel to ensure that a function of two-way circulation is realized; and the movement of a valve core is reduced by the damping structures, so that the service life of the expansion valve components is prolonged and the energy efficiency ratio of the expansion valve components is improved, thereby being of great significance for energy conservation and emission reduction.
