Description

For the pressure pot in water cleaning systems

Technical field

Household water purification equipment is the utility model is related to, more particularly to a kind of pressure pot being used in water cleaning systems.

Background technology

Pressure pot is mainly used in water storage in household water purification system, and it is larger typically to bear pressure.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 in order to 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, which has plastic pressure bucket to be difficult to pressure-bearing, to be caused to explode, and danger is caused to kitchen in family, also causes producer to cause huge reparation Loss.

Utility model content

Goal of the invention of the present utility model is to solve the problems, such as existing pressure pot security difference, there is provided one kind is used for net Pressure pot in water system, when the water in pressure pot, which is filled it up with, produces water injection pressure, pressure limiting valve closes water inlet, so as to limit bucket Interior pressure continues to increase, and prevents pressure pot from bursting；When water filling external pressure is shed, pressure limiting valve, which automatically opens up, is changed into normally opened.

In order to realize foregoing invention purpose, the utility model employs following technical scheme：

For the pressure pot in water cleaning systems, including pressure pot body, pressure pot body top opens up one and entered for water Enter the inlet and outlet in bucket, the import and export is additionally provided with the pressure limiting valve for preventing overvoltage；The pressure limiting valve is to exceed certain injection water Cut-out water filling can be closed automatically when pressing threshold value, automatically open up the normally open valve of water outlet during less than threshold value again.

Preferably, pressure limiting valve includes valve seat, ball valve core and the piston component for driving ball valve core to rotate；Valve seat It is provided with the first disengaging aquaporin, the second disengaging aquaporin and bypass channel, the first disengaging aquaporin and the second disengaging aquaporin Between valve seat be provided with ball valve core installation cavity；Piston component installation cavity, ball valve are provided with the valve seat of bypass channel output end Valve element is located in ball valve core installation cavity, and ball valve core input connects the piston component, and ball valve core output end is positioned at the Between one disengaging aquaporin and the second disengaging aquaporin；Piston component includes piston, the valve rod for driving ball valve core to rotate And spring；Piston includes pressure input face and output face；Valve rod one end is fixedly connected with ball valve core, the valve rod other end and the work Rotatable engagement is filled in, spring is located in piston component installation cavity, and is enclosed on outside the valve rod other end；One end of spring is connected in piston component Install on cavity wall, the other end is against piston output face；Piston seal is installed in piston component installation cavity and pressure input face Towards bypass channel output end.

Preferably, the piston is provided with inside spin line, the valve rod other end is provided with external spiral line.

Preferably, the middle part of the piston output face is provided with stud, stud is provided with external spiral line；On the valve rod other end Provided with the inner bolt hole matched with the stud.

Preferably, valve rod one end seals with being provided with a circle in the piston component installation cavity of the valve core junction of receiving Filler, the top of a circle airtight and watertight padding are provided with annular pressing ring, and one end of spring compresses airtight and watertight padding by annular pressing ring, so as between It is connected in succession on piston component installation cavity wall.

Preferably, the piston component installation cavity between piston and annular pressing ring forms a closed cavity；On pressure limiting valve Provided with display column, display column includes fixed with valve seat outer wall and stretching out in the transparent post of the valve seat outer wall and positioned at transparent post Interior floating plug；The inner sealing of transparent post connects the cavity；In the floating plug sealing installation and the transparent post.

Preferably, bypass channel is L-shaped passage, the output end of bypass channel corresponds to the piston centre.

Compared with prior art, a kind of pressure pot being used in water cleaning systems of above-mentioned technical proposal is employed, is had such as Lower beneficial effect：

First, pressure pot of the present utility model, when the water in pressure pot is filled it up with, the pressure increase in external water pipe, when outer When the pressure that boundary's water pipe is applied to bypass channel is more than back-moving spring in pressure limiting valve, piston pushes driving stem rotation, so that according to Find to close pressure limiting valve by ball valve, and then limit pressure in bucket and continue to increase, prevent pressure pot from bursting.

2nd, due to the internal pressure of above-mentioned pressure pot it is big when, will be conducted to bypass channel, i.e. internal pressure quilt as long as pressure limiting valve opens 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 reduces, without being further added by Blocked up wall thickness is it is ensured that the ability to bear of pressure, effectively reduces materials'use amount and the weight of pressure pot.

3rd, the water inlet on current pressure pot and exhalant canal are usually same, therefore, and meanwhile it is net in pressure charge bucket The pressure limiting valve for entering and going out of water will also ensure that pressure limiting valve can automatically open up when external pressure is shed.And the disengaging side of more pipelines The pressure pot of formula is eliminated in water cleaning systems already, therefore pressure limiting valve of the present utility model just make use of bypass channel, these Novel structure, realize the purpose of above-mentioned pressure limiting.After large-scale production, pressure limiting valve cost is low, durable and even if spring breaking down Afterwards, the water also only resulted in pressure pot can not flow out, but not cause pressure limiting to be failed, and ensure that pressure pot does thin devoid of risk.
