Abstract

The invention discloses a unidirectional drying filter which comprises a barrel (8), wherein the barrel (8) is provided with an inlet and an outlet, a molecular sieve (7) is arranged in the barrel (8), a first filter disc (9) is arranged between the molecular sieve (7) and the outlet, and a spring (4) and a second filter disc (5) are sequentially arranged between the inlet and the molecular sieve (7). The unidirectional drying filter is characterized in that at least one third filter disc (3) is also arranged in the spring (4). The third filter disc is arranged in the spring of the unidirectional drying filter provided by the invention, a bigger flow space is still left after refrigerant enters through the inlet, the flow requirement can be ensured, and meanwhile, the third filter disc is combined with the first and second filter discs, so that the filter capability can be exerted to the maximum extent.

Description

technical field

[0001] The invention relates to the technical field of filters, in particular to a one-way dry filter. Background technique

[0002] During the operation of the refrigeration device, since the refrigerant and refrigerating oil will produce solid powder, dirt and other impurities, it is easy to block the throttling parts. In addition, the trace moisture contained in the refrigerant is more harmful to the refrigeration system. Therefore, it is necessary to treat the refrigerant or Freeze the oil for drying and filtering.

[0003] The one-way drying filter is usually installed between the condenser and the expansion valve. It is mainly used for one-way flow of refrigeration pipelines. It has a component for drying and filtering inside, which can dry and filter the refrigerant, so that Effectively prevent filtrate or soluble matter from entering the key components of the refrigeration system, so as to ensure that the system is running at its best.
