Description
Technical field
The utility model belongs to plumbing technical field, in particular to a kind of non-negative pressure water service system.
Background technique
Non-negative pressure water service system is using advanced Control Technique of Microcomputer, in conjunction with performance frequency converter speed regulator, according to life
How much automatic adjustment pump rotary speeds of water consumption or the number of units of increase and decrease operation water pump, realize constant pressure water supply.
The series non-negative pressure water service system equipment pressure is reliable and stable, energy-efficient, is residence district, waterworks, work
The ideal supply equipment such as mine enterprise, its excellent ratio of performance to price of non-negative pressure water service system is other any supply equipments without
Method analogy, be to replace water tower, high water tank, without the optimal water system of tower watering machine.
The working principle of non-negative pressure water service system is as follows: current stabilization pot type non-negative pressure water-supply device directly connects with city planting ductwork
It connecing, series connection laminates water supply on the basis of city planting ductwork residual compression,
(1) constant pressure water supply: when city planting ductwork water supply is greater than user's water consumption, current stabilization pot type non-negative pressure method of water supply is set
Standby constant pressure water supply, stores a certain amount of artesian water at this time in steady-flow tank；
(2) it eliminates negative pressure: when user's water consumption increase causes city planting ductwork and steady-flow tank junction pressure to decline, working as pressure
When being reduced to 0 or less relative pressure, negative pressure is formed in steady-flow tank, the air intake valve of vacuum suppresser is opened, and atmosphere enters steady
Flow tank.At this point, steady-flow tank is equivalent to the opening water tank with free surface, pressure is identical as atmosphere, and negative pressure is eliminated.Water
When position drops to setting value, fluid level controller passes to the control system in frequency-conversion control cabinet for signal is controlled, and controls pressuring machine
Group stops working, and user cuts off the water；When user's water consumption reduces, water level rises in steady-flow tank, and gas is vented from vacuum suppresser
Valve excludes, and after pressure recovery is normal, Pressure Unit starts automatically again, resumes water supply；
(3) cut off the water stopping function: when city planting ductwork is cut off the water, Pressure Unit is automatically stopped fortune under fluid level controller control
Row, city planting ductwork supply water after recovery, and automatic starting restores normal water supply again.
The most key component is steady-flow tank to existing non-negative pressure water service system in the process of running, currently, steady-flow tank institute
It has the disadvantage that
Although the water source of tap water pipe network has carried out primary filtration by strainer valve before entering to steady-flow tank,
It is, due to needing to guarantee that tap water pipe network has enough water flows, the degree of filtration of strainer valve is not high, is often
Biggish suspended impurity is filtered, the water source being discharged into steady-flow tank is not still complete pure water.
Have above-mentioned it is found that a certain amount of pressure-bearing can be stored in steady-flow tank when steady-flow tank is in constant pressure water supply state
Water, in particular, artesian water can be stored in steady-flow tank for a long time in night water consumption lesser period, as a result, for a long time,
Will be adhered on the inner wall of vacuum tank subtle suspended impurity or moss etc. contained in artesian water (be similar to water vat inner wall or
Well inner wall), and the bur on pressure stabilizing top tank structure can also be cumulative, so, steady-flow tank using certain time limit after, need
Its inner wall is cleared up, at this time, on the one hand, need to shut down progress maintenance and cleaning；On the other hand, the volume of steady-flow tank is general
