Abstract
The utility model relates to a combined-type backwashing drinking water filter, which is formed by that a multifunctional core tube, a fine filtering core 3, a coarse filtering core 2 and a casing 1 are arranged on the base of a flat plate circle on the upper surface of a valve body 8; the lower surface of the valve body 8 is provided with a raw water outlet 6, a purified water outlet 9 and a water draining outlet 11; a valve rod 12 at the middle part of the valve body 8 is provided with three arced grooves and an n-shaped water channel 7; a three-way water feeding valve 5 is connected with the inlet hole of a casing 1 and the inlet hole of the raw water outlet. The utility model can repeat multiple times of filtration with simultaneous and convenient backwashing, and has compact structure and easy manufacture.
Description
The utility model relates to a kind of drinking-water filter for installation, especially can backwash and compound drinking-water filter.
The drinking-water filter of being sold in the market, there is the multiple water treatment method to arrive aseptic, tasteless, the no objectionable impurities of drinking water with this, satisfy human sanitary standard to Drinking Water, no matter adopt active carbon filtration, or ion-exchange, or precipitation ... all exist single filter method, can not remove harmful substance fully, not possess backwash simultaneously, recover deficiencies such as drinking-water filter operate as normal.Disclose " a kind of domestic inorganic ultrafiltration water purification device " at number of patent application 94245393.X and still existed above-mentioned deficiency.
The purpose of this utility model provides a kind of drinking-water filter, it can not only repeat to water filtration and also can backwash filter core, make the drinking-water filter recover operate as normal.
The purpose of this utility model is achieved in that the pedestal in several holes on the plane that the garden is arranged above the valve body of its garden shape, former water out is arranged below the valve body, pure water inlet and drain outlet, in the middle of the valve body is valve rod, multi-functional core pipe is arranged on the pedestal of valve body, smart filter core, coarse filter element and porose housing, three arc grooves are arranged on valve rod, communicate with drain outlet respectively, multi-functional core pipe delivery port and pure water inlet communicate, Yuan Shui and former water out communicate, valve rod hollow between former water out and the pure water inlet is Jiong shape water channel, and the inlet opening of the water intaking valve of threeway and the inlet opening of shell and former water out joins.Move valve rod and make the D hole of pedestal and the F hole of drain outlet, and the M hole of the delivery port S hole of multi-functional core pipe and pure water inlet, all be not communicated with, when only connecting the N hole site of the H hole of former water and former water out, the threeway water intaking valve is removed to former water inflow H hole site, and the former water of running water pipe does not purify like this, by arc groove EE, to the N hole, flow out through former water out; Remove valve rod again and make the D hole of pedestal and the F hole of drain outlet, and the N hole of the H hole of former water and former water out, all be not communicated with, when only connecting the M hole of the delivery port S hole of multi-functional core pipe and pure water inlet, the threeway water intaking valve removed to the A hole that makes former water from housing enter coarse filter element, arrive smart filter core and multi-functional core pipe again through the water of infiltration, after the multiple times of filtration, purify waste water from multi-functional core pipe delivery port S hole to arc groove CC, through M hole and pure water inlet and flow out; Equally, during backwash, move valve rod and make S hole and M hole, the equal access failure in H hole and N hole is only connected D hole and F hole, the threeway water intaking valve moved to make former water by H hole and G hole, flow into the K hole and the S hole of water channel, rhetorical question flows into multi-functional core pipe, smart filter core of reverse osmosis and coarse filter element, make the cartridge surface foul with D hole and the arc groove F hole of former water, finally discharge through drain outlet by pedestal.
Owing to adopt such scheme, can repeat multiple times of filtration, backwash easily simultaneously, compact conformation is made easily.
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is a vertical section of the present utility model structural map.
Among the figure: the former water out 7-of the smart filter core 4-multi-functional core pipe 5-water intaking valve 6-of 1-housing 2-coarse filter element 3-water channel 8-valve body 9-pure water inlet 10-O shape cushion rubber 11-drain outlet 12-valve rod 13-porous loam cake
The dull and stereotyped pedestal that several holes of garden shape are arranged above the valve body 8 as shown in drawings.Go up and multi-functional core pipe 4, smart filter core 3, coarse filter element 2 is connected with porose housing 1, former water out 6 is arranged below the valve body 8, pure water inlet 9 and drain outlet 11, in the middle of the valve body 8 is valve rod 12, is Jiong shape water channel 7 what valve rod 12 had three arc grooves and hollow, and the A hole of threeway water intaking valve and shell and the H hole on the pedestal join.
Be the multi-functional core pipe 4 of garden cylindricality, there is porous loam cake 13 upper end, makes the water can be from top to bottom, or flows from bottom to top, and there is magnet ring the lower end, makes hydromagneticization, and there is mineralized material the centre.
For valve body 8 seals mutually with valve rod 12, a plurality of O-ring seals 10 are arranged on valve rod 12.
