Universal multifunctional pre-filter

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...

Problems solved by technology

[0002] In industrial production and household applications, or in raw water testing, clean water is required for cooling, dilution or domestic applications, but conventional water contains impurities, which need to be filtered before being sent in. The traditional way of entering and exiting water filters is straight in and out. Out-type, with 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, cleaned and then installed. The operation is troublesome and affects production operations to a certain extent.
