Description
Technical field
The present invention relates to the pressure pot in purifier, and in particular to a kind of explosion-proof pressure bucket on purifier.
Background technology
Operationally, current filter out trickle harmful impurity therein to water purifier by reverse osmosis membrane：Bacterium, virus,
Radioactive substance and heavy metal, organic compound etc..
From the point of view of water purifier principle, only pure water just can will be left out and be discharged by reverse osmosis membrane, impurity.
Because purifier water outlet amount is too small, it is impossible to enough meet the requirement that user fetches water at any time, thus when user does not fetch water, pure water
Machine it is the same work, obtained pure water is first stored in pressure pot, when user needs to use water, directly from pressure pot to
Outside exports, and user need not just take time to wait water processed.Water purifier pressure pot serves the effect of equilibrium water amount and pressure, keeps away
Exempt from safety valve frequently to open and the frequent moisturizing of automatic water compensating valve.
Pressure pot point plastic pressure bucket, carbon steel pressure bucket etc. from material.Existing pressure pot is generally by staving, air bag, water
Mouth, valve inside etc. are constituted.During empty barrel, intracapsular pressure is about 0.5kg or so.After pure water is slowly injected in bucket, air in air bag
Compressed, air pressure also gradually rises, until gasbag pressure reaches water purifier high-voltage switch gear setting pressure, machine down.Work as pure water
After tap is opened, the pure water being stored in pressure pot can be extruded by the air pressure in air bag.
When extraneous pipeline in bucket to water is filled, because hydraulic pressure gradually increases, air pressure also rises therewith, and hydraulic pressure is gentle
The pressure of pressure is equal all the time, and two will be formed if the high-voltage switch gear of Pressured water tank front end breaks down, in pressure pot solely
The vertical gentle higher-pressure region in water higher-pressure region, easily explosion, gases at high pressure and liquid produce greatly punching in the moment of pressure drum rupture
Power is hit, there is certain threat to personal safety.
Therefore in the selection of pressure pot, water purifier manufacturer can do two kinds of selections：
1. metal pressure pot, such as carbon steel pressure bucket are selected, and it is difficult explosion, but weight is big, high cost, processing
Difficulty is also high；
2. plastic pressure pot is selected, and processing is relatively simple, but requires that its wall thickness is larger, pressure pot is born
The hydraulic pressure of more than 8kg, therefore required material is more, causes weight larger.
