Embodiment Construction

[0021] The purpose of the present invention is to provide a one-way dry filter, which can meet the flow rate requirement on the premise of exerting the best filtering capacity.

[0022] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Please refer to figure 2 , figure 2 It is a structural schematic diagram of a specific embodiment of the one-way drying filter provided by the present invention.

[0024] The one-way dry filter provided by the present invention includes a cylindrical body 8, which has an inlet and an outlet connected to the refrigerant inlet pipe and outlet pipe respectively, and the inlet and outlet can pass through the inlet end cover 1 and the outlet end cover 12 respectively. Sealing; Molecular sieve 7 is set in cylinder body 8, Molecular sieve 7 p...

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. [0004] Filt...
