Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment is as follows:
referring to fig. 1-3, a dual-switch dual-filter includes two filter cartridges 3, the two filter cartridges 3 are respectively connected through a ball valve assembly, a filter element 2 is disposed inside the filter cartridge 3, an upper cover 1 and a bottom cover 4 are respectively disposed at the top end and the bottom end of the filter cartridge 3, the filter cartridge 3 is connected with the bottom cover 4 through a first bolt 7 and a first nut 8, and a first gasket 9 is disposed at the joint of the first bolt 7 and the first nut 8.
In this embodiment, the ball valve assembly is provided with two and respectively connected with two filter cartridges 3. Guarantee switch and filterable effective control, control one or two cartridge filters 3 simultaneous workings, or the part work, maintenance can be saved a large amount of time cost by one work.
In this embodiment, the ball valve assembly comprises a three-way ball valve 5, and the three-way ball valve 5 is connected with two filter cartridges 3 through a second bolt 11 and a second nut 12. The disassembly and the assembly of the device are convenient.
In this embodiment, a sealing gasket 14 is disposed between the filter cartridge 3 and the three-way ball valve 5. So that the connection between the filter cartridge 3 and the three-way ball valve 5 is firmer and the sealing performance is better.
