Abstract
The invention relates to household water purifying equipment, in particular to a pressure barrel for a water purifying system. The pressure barrel for the water purifying system comprises a pressure barrel body; an access port for feeding water in the barrel is formed in the top end of the pressure barrel body, and is provided with a pressure limiting valve for preventing excessive pressure; and the pressure limiting valve can automatically cut off the water injection when exceeding a certain water injection pressure threshold, and can automatically open a normally open valve for discharging water when being lower than the threshold. When the water is fully filled in the pressure barrel to generate the water injection pressure, the pressure limiting valve closes a water inlet to limit continuous increment of the pressure in the barrel to prevent burst of the pressure barrel; and when the water injection pressure is relieved, the pressure limiting valve automatically opens to become normally open.
Description
Technical field
The present invention relates to Household water purification equipment, more particularly to a kind of pressure pot in water cleaning systems.
Background technology
Pressure pot is mainly used in water storage in household water purification system, typically bears pressure larger.With the fierceness of competition, pressure
The price of bucket declines, and Plastic Drum constantly substitutes steel drum.In existing market, plastic pressure bucket is for cost-effective, plastic wall
The ratio of manufacture is relatively thin.Because the influence of manufacturing process, after excess load water storage, plastic pressure bucket can progressively expand, often
Nian Douhui has plastic pressure bucket to be difficult to pressure-bearing causes blast, and danger is caused to kitchen in family, also causes that producer causes huge reparation
Loss.

Compared with prior art, a kind of pressure pot in water cleaning systems of above-mentioned technical proposal is employed, with such as
Lower beneficial effect：
First, pressure pot of the invention, when the water in pressure pot is filled it up with, the pressure in external water pipe increases, when extraneous water
Pipe is applied to the pressure of bypass channel more than during back-moving spring, piston pushes driving valve rod rotation, so that by ball in pressure limiting valve
Valve finds to close pressure limiting valve, and then limits pressure continuation increase in bucket, prevents pressure pot from bursting.
2nd, due to the internal pressure of above-mentioned pressure pot it is big when, as long as pressure limiting valve opens will conduct to bypass channel, i.e. internal pressure quilt
Pressure limiting, pressure limiting is closed by ball valve, and the hydraulic pressure that ball valve is born is very high.Therefore wall thickness demand reduction, without being further added by
Blocked up wall thickness is it is ensured that the ability to bear of pressure, effectively reduces the weight of materials'use amount and pressure pot.
3rd, on current pressure pot water inlet and exhalant canal is usually same, therefore, while net in pressure charge bucket
The pressure limiting valve for entering and going out of water will also ensure that pressure limiting valve can be automatically opened up when external pressure sheds.And many turnover sides of pipeline
The pressure pot of formula is eliminated in water cleaning systems already, therefore pressure limiting valve of the invention just make use of bypass channel, and these are novel
Structure, realize the purpose of above-mentioned pressure limiting.After large-scale production, even if after pressure limiting valve low cost, durable and spring breaking down,
Also only resulting in the water in pressure pot cannot be flowed out, but pressure limiting will not be caused to fail, it is ensured that pressure pot does thin devoid of risk.
