Technical Field
The utility model relates to a valve conversion adapter and a water purifier, and belongs to the technical field of water filtering devices.
Background
In order to extend the life of UF (Ultra Filtration) filters and to protect Filtration performance, POE (Point of entry) water purifiers installed at the inlet of building or residential pipelines require regular flushing of the UF filter element to forcibly remove impurities such as sludge, silt particles, and pipeline shedding from the filters.
The existing water purifier is provided with a multifunctional softening valve with a back flushing function, the existing multifunctional softening valve is only suitable for an internal pressure type UF filter, as shown in figure 9, when water is purified, raw water enters a hollow cavity of a hollow fiber ultrafiltration membrane wire 19 of the UF filter from a raw water inlet 901 of a valve 9, the hollow fiber ultrafiltration membrane has the function of selectively penetrating substances under the driving of pressure, substances with larger pore diameters than the ultrafiltration membrane are trapped in the hollow cavity of the membrane wire 19, and water filtered by the ultrafiltration membrane flows out from a purified water outlet through a central pipeline 20 of the filter, so that the effect of purifying the water is achieved; as shown in fig. 10, during back flushing, the switching valve 9 allows flushing liquid to enter the central pipeline 20 of the UF filter through the raw water inlet and enter the tank body, the flushing liquid enters the hollow cavity of the ultrafiltration membrane wires 19 under the action of pressure, and pollutants in the hollow cavity are discharged upwards along with the flushing liquid from the flushing liquid drain. For example, an energy-saving multifunctional softening valve disclosed in the chinese patent application No. 201020267651.4, a water treatment filter valve with a closing function disclosed in the chinese patent application No. 201720650460.8, and a soft water replenishing multifunctional soft water valve disclosed in the chinese patent application No. 201210086515.9, wherein the valves disclosed in the above patent documents are all suitable for use in an internal pressure UF filter.
Because harmful substances filtered by the internal pressure type ultrafiltration membrane remain in the membrane wires 19 of the ultrafiltration membrane, the membrane wires 19 are easy to block, unlike the internal pressure type ultrafiltration membrane, external pressure type inflow water permeates from outside to inside, so that pollutant substances in inflow water are trapped and adhered to the outer surface of the membrane wires 19 or the pipe wall, the membrane wires 19 cannot be blocked, the external pressure type ultrafiltration membrane has larger sewage containing capacity than the internal pressure type ultrafiltration membrane, and the cleaning period is relatively longer. However, the existing valve suitable for the external pressure type UF filter only has the function of softening water, but does not have the cleaning function, and the water inlet/outlet direction of the multifunctional softening valve with the cleaning function is not suitable for the external pressure type UF filter, if the multifunctional softening valve is directly structurally modified to be suitable for the external pressure type UF filter, a new mold needs to be manufactured, and the modification cost is high.
Therefore, there is a need for a valve switching adapter that can change the flow direction of raw water and purified water of an existing multi-function softening valve so that an external pressure type UF filter can be cleaned using the existing multi-function softening valve.
