Embodiment example

[0042] When filtering, close the drain valve 6 at the end of the filter housing 5, turn the adjusting handle 1 to adjust the water outlet port 809 of the adjusting valve 8 to a position communicating with the water outlet port 306 of the water inlet and outlet support 3. The raw water to be filtered is from The water inlet channel 203 of the dual-channel valve 2 enters through the water inlet 208 and enters the inner cavity composed of the water tank one 206 and the water tank 305, then flows through the raw water inlet 311 and enters the filter housing 5 through the water inlet channel 811 of the regulating valve 8. Under the action of water pressure, the raw water is intercepted and filtered by the filter screen 72 of the filter 7 and enters the inner cavity of the filter cartridge frame 71. The dirt is intercepted and embedded in the mesh of the filter screen 72. The purified water after filtration is Under the action of water pressure, it flows upwards into the water passage...

Abstract

The invention discloses a universal multifunctional pre-filter, which comprises a regulating handle, a dual-channel valve, a water inlet and outlet support, an eccentric connecting nut, a filter housing, a blow-down valve, a filter and a regulating valve. The filter is loaded into the filter housing, the regulating valve is installed in the water inlet and outlet support, then the water inlet andoutlet support is connected to the filter housing, the regulating handle is in connection with the regulating valve 8 so as to be convenient for adjusting the working mode of the filter by an angle rotation mode, and the dual-channel valve is in connection with the water inlet and outlet support through the eccentric connecting nut. The universal multifunctional pre-filter provided by the invention can reach one of the filtering, backwashing and closing functions as long as rotating the angle position of the adjusting knob, also can achieve dismantling of the filter housing and the filter forcleaning under a closed state, and has the characteristics of large filter flow, simple operation, convenient application and simple maintenance process.

Description

Technical field [0001] The invention relates to the technical field of water impurity filtering devices, in particular to a universal multifunctional pre-filter. Background technique [0002] Industrial production and household applications, or raw water testing, need to use clean water for cooling, dilution, or domestic applications. However, conventional water contains impurities and needs to be filtered before being sent in. The traditional water filter's inlet and outlet methods are straight-in and straight-in. Out-type, there is a mesh filter device in the middle. After long-term use, the impurities in the filter device need to be cleaned. When cleaning, the filter device needs to be removed and cleaned before installation. The operation is troublesome and affects the production operation to a certain extent. Summary of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a universal multifunc...
