Straight-through type water quality filtering guarantee system for secondary water supply

Abstract

The invention discloses a straight-through type water quality filtering guarantee system for secondary water supply, which comprises a shell connecting assembly, a filtering guarantee device, a water flow direction switching assembly, a back-washing assembly, a visual observation device and a control cabinet system device. The shell connecting assembly is provided with a shell cylinder, a water inlet flange and a water outlet flange, the water inlet flange is arranged at the water inlet end of the shell cylinder, a water outlet flange is installed at the water outlet end of the shell cylinder, the filtering guarantee device is installed in the shell cylinder, the water flow direction switching assembly is installed in the shell cylinder in a penetrating mode, the back-washing assembly and the visual observation device are both installed on the side face of the shell cylinder, and the visual observation device is installed on the outer side face of the shell cylinder and located on the lower portion of the filtering guarantee device. The back-washing assembly is connected with the control cabinet system device through a wire harness. Impurities in the filter can be directly observed, back-washing is carried out regularly to discharge the impurities, the maintenance difficulty of a common filter is reduced, the labor cost input is reduced, and the safety of secondary water supply equipment and water quality is ensured.

Description

technical field [0001] The invention relates to the field of a straight-through water quality filtering guarantee device system for secondary water supply, and specifically belongs to a straight-through water quality filtering guarantee system for secondary water supply. Background technique [0002] As the key core equipment for people's domestic water guarantee, secondary water supply equipment plays an important role in guaranteeing the "last mile" safe water for people's lives. However, when the tap water reaches the secondary water supply equipment through the municipal pipeline, it will often bring some impurities accumulated in the municipal pipeline to the secondary water supply equipment, and even pressurize it to the user through the water pump, which will affect the water quality of people's domestic water; at the same time When the water pump supporting the secondary water supply equipment operates in an environment with impurities, the service life of the water ...

AI Technical Summary

Problems solved by technology

And the common Y-type strainer that existing secondary water supply equipment system uses, although have certain filtering function, there are following problems in actual use: 1, use operator can't know the impurity situation accumulated inside common Y-type strainer , it is impossible to know when to clean the ordinary Y-type filter to remove impurities; 2. When the ordinary Y-type filter is actually cleaned and discharged, the filter needs to be removed and cleaned manually, which makes the overall maintenance difficult and the maintenance cost is high.
