Inner core assembly

Abstract

The invention discloses an inner core assembly. The inner core assembly is composed of a filter element end cover, a flow guide pipe, an RO filter, seal rubber rings, a purified water outlet and a concentrated water outlet; the filter element end cover is arranged at the top of an inner core assembly body and is provided with the purified water outlet and the concentrated water outlet, the purified water outlet is formed in the middle of the filter element end cover, and the concentrated water outlet is formed in the left side of the purified water outlet; the RO filter is connected with the inside of the filter element end cover in an inserting mode and internally provided with a center pipe; raw water enters from the lower end face, and the passing raw water is purified; the flow guide pipe is installed on the top of the center of the RO filter, and the connection portion of the flow guide pipe and the center pipe of the RO filter and the connection portion of the flow guide pipe and the purified water outlet of the filter element end cover are provided with the seal rubber rings. Through simple components, such as the filter element end cover, the flow guide pipe, the seal rubber rings and water seal adhesive tape, and unique design of waterways, the raw water, the purified water and the concentrated water are separated in a limited mode, and the reliable sealing and effective filtration functions are achieved.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to an inner core assembly. Background technique [0002] The filter is an indispensable device on the conveying medium pipeline. It is usually installed at the inlet end of the pressure reducing valve, pressure relief valve, fixed water level valve, and other equipment of the Fanggong filter; the filter has a filter cartridge of a certain size Finally, the impurities are blocked. When cleaning is required, just take out the detachable filter cartridge and reinstall it after treatment. Therefore, the use and maintenance are extremely convenient. [0003] Generally, the RO filter (reverse osmosis membrane filter) is composed of an RO membrane filter element and several auxiliary waterway elements in the inner core. However, most of the auxiliary waterway elements used in the RO filter core on the market currently have structures Complexity, many parts, and unreliable sealing performa...
