A kind of valve body
Technical field
This application involves water purification fields, and in particular to valve body.
Background technique
Using the water purification system of ultra-low-pressure reverse osmosis film no benzene, tap water directly can be converted into straight drink without electricity
Water.Domestic water purifying market is gathered around and is had broad application prospects.But the problem of head cup water, annoyings always all kinds of permeable membranes
Application effect, wherein ultralow pressure permeable membrane is especially prominent.
The head cup water, after referring to that water purification system is out of service, the condensed water being trapped in putamina, with the diaphragm other end
Direct drinking between interpenetrated by pressure, make the direct drinking at water purification end as the growth water quality of time is close to condensed water, because
This makes the water purification being trapped in putamina become underproof drinking water.
For ultra-low-pressure reverse osmosis film, such situation is more prominent.If the frequency that a water purifier is opened is very frequent,
And duration is again shorter, therefore causes the water being trapped in putamina unqualified.In this case it fetches water more frequent, makes
At drinking, underproof water is more.So storing direct drinking using water tank, if not preventing system frequent starting, it is detained in water tank
Direct drinking, the short time just it is as tap water or even worse.In recent years household water-purifying machine market, all big enterprises release big logical more
Measure direct current water purifier.And consumer actual use in show as dosage it is few, using frequent feature.Therefore, consumer is caused to exist
What is often drunk in actual use is head cup water.Meanwhile water purification system frequent starting increase its automatically controlled component damage it is several
Rate.
Water purification is stored using water butt for the water purifier of primary flux, this water purification system mostly uses greatly pressure switch
Control water purification system starting, and pressure pot, pressure switch and clear water faucet be it is direct-connected, when open clear water faucet water intaking when,
The pressure at water purification end decays rapidly, causes water purification system starting uncontrollable.Meanwhile water butt using closed air bag come water storage,
The water butt often causes secondary pollution into air accidentally due to using, and this pollution is difficult to remove.First is that consumer
Do not know about that there are this pollutions, second is that the basic method for removing this pollution is exactly to replace the water butt, thus give consumer
Bring economic loss.
When user collects condensed water, in order to avoid the condensed water of collection is overflowed, generally set using a biggish bucket
Beside cabinet, both unsightly, also it is in the way very much.Unsatisfactory thing often can be still had to occur --- spilling water.
