Description
The utility model relates to a kind of water purification machine for preparing pure water, particularly relates to a kind of reverse osmosis water purification machine.
Along with the quickening of the raising of people's living standard and rhythm of life and owing to worry factor such as water pollution, existing increasing people begins purified drinking water, and the domestic water purifying machine that therefore is used to prepare pure water also arises at the historic moment.At present, the reverse osmosis water purification machine of selling on the domestic market is assembled into the master with imported product or import loose mail.In this water purification machine, adopt topping-up pump to increase line pressure mostly, and use topping-up pump to need electricity consumption, therefore improved use cost.This water purification machine also adopts the air pressure type water storing tank, and a water completely back jar internal pressure extrudes pure water.In addition, the pre-filtering parts of this water purification machine, water storing tank, rising pipe etc. are the dispersive parts and are installed separately, thus inconvenience is installed, and increased the volume of water purification machine.
The purpose of this utility model is to overcome the deficiency of existing reverse osmosis water purification machine and a kind of compact construction is provided, and volume is little, and it is fast convenient to clean, and installs and uses and easy to maintenance, need not electricity consumption, safe and reliable reverse osmosis water purification machine.
The purpose of this utility model realizes by following technical solution:
The utility model comprises water intaking valve 1, prefilter 2, reverse osmosis filter 3, cistern 4, outlet valve 5, flow-limiting valve 6 and pipeline 7, its main points are also to be provided with reverse osmosis membrane flushing pipeline 8, described flow-limiting valve 6 is by valve body 61, be fixed in the end cap 62 at valve body both ends and be adhered to the intravital microporous fibre 63 of valve and constitute, described cistern 4 is wall-hanging box-shaped cistern, and described each parts are installed on cistern 4 outer walls 41.
Described reverse osmosis membrane flushing pipeline 8 is that flush valve 81 is linked to each other with the exit end of reverse osmosis filter 3 by pipeline 82, on the pipeline between flush valve and the reverse osmosis filter, be connected with threeway 83, then be connected with flow-limiting valve 6 on the pipeline between threeway 83 and the water draining tee 84, the two ends of water draining tee link to each other with flow-limiting valve with flush valve respectively.
Described prefilter 2 is fixed on the prefilter support 21, the prefilter support then is screwed on the cistern 1, described reverse osmosis filter 3 fixes by steel card and the cistern 1 that links to each other with housing 31, and described flush valve 81 is fixed on the cistern 1 by its permanent seat 811.
Principle of work of the present utility model as shown in Figure 1.Tap water is through water inlet pipe 71, water supply connector 24 enters prefilter 2, coarse filtration layer 231 through filter core 23, behind activated carbon filter layer 232 and filter bed of essence 233 pre-flocks, flow out by the water out adapter on the prefilter base 21 25, and enter the water-in of reverse osmosis filter, after in reverse osmosis membrane 31, filtering through pipeline 7, pure water flows out from water outlet 34, and enters water storage tank 4 through pipeline.Dense water is discharged from the dense water out 35 of reverse osmosis filter bottom, leads to flow-limiting valve 6 and flush valve 81 respectively through being connected in ducted threeway 82.The water of flow-limiting valve of flowing through is discharged through delivery pipe 72.Flow-limiting valve adopts the micropore flow restriction, can improve pressure in the pipeline, makes the reverse osmosis membrane water outlet.Flush valve 81 is closed when the system pure water.Open flush valve, water is directly broken through from reverse osmosis membrane 31, and through flush valve and water draining tee 83 that is attached thereto and delivery pipe 72 discharges, the dirt in the reverse osmosis membrane is gone out with water.After pure water is expired in the water storage tank 4, can from upflow tube 42, overflow.When in the water storage tank water being arranged, open outlet valve 5, just can from rising pipe, receive pure water.
Be separated by with existing reverse osmosis water purification machine and compare, the utlity model has following positively effect:
One, the utility model need not electricity consumption and can prepare pure water, has not only reduced cost, and safe and reliable.
Two, Du Te reverse osmosis membrane flushing pipeline can in time promptly wash the impurity on the reverse osmosis membrane, can effectively prolong its work-ing life.
Three, owing to be designed to wall-hanging structure, therefore make volume-diminished, structure become very compact, mounting, commissioning and maintenance is all very convenient, and does not take the usable floor area in room.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the flow-limiting valve structural representation.
Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail.
As shown in Figure 1, the utility model comprises water intaking valve 1, prefilter 2, reverse osmosis filter 3, cistern 4, outlet valve 5, connecting tube 7 between flow-limiting valve 6, each parts and reverse osmosis membrane flushing pipeline 8.
