A kind of water-purifying machine with pressure-pot
Technical field
The present invention is a kind of water-purifying machine with pressure-pot, belongs to the renovation technique of the water-purifying machine of being with pressure-pot.
Background technology
The water-purifying machine of existing band pressure-pot adopts the control mode of coming control pressure jar 3 system water by the cut off value of high-voltage switch gear 4 and reset values mostly.High-voltage switch gear is controlled opening and closing according to the difference of pressure-pot water level: when the full moment of pressure-pot water, promptly reach the pressure cut off value that high-voltage switch gear 4 is set, system is out of service; When the pressure-pot water level reduces when reaching pressure that high-voltage switch gear 4 sets and restarting value, system restart moves.But in the actual motion, have problems in following two stages:
When the pressure-pot water level rise to will water full, when being about to reach the pressure cut off value that high-voltage switch gear 4 sets, have the inefficient operation interval of a water-purifying machine reverse osmosis system, in case enter this interval, the water purifying rate of recovery is low, substantially less than 5%, system water is very consuming time.So this stage not only wastes water, efficient is low, and have influence on the life-span of filter.
When water tap 7 was opened, it was the dynamic value of in-pipe flow when moving that high-voltage switch gear 4 obtains force value, and theoretical value is that 0 (this value is ignored pipe damping power; And in the actual test this force value less than 2 kilograms), be the reset signal of high-voltage switch gear 4.After pressure-pot water was full, as long as the water of a little in the leading 7 drain pressure jars 3 of fetching boiling water, high-voltage switch gear will be sensed reset signal in 4 short period of time, and the system that makes makes water again, and reached the pressure cut off value just stop in the operation interval of poor efficiency.If frequent water intaking, then system's frequent starting causes the life-span of electrical element to shorten.
Summary of the invention
The objective of the invention is to consider the problems referred to above and provide a kind of system that avoids to be in inefficient operation interval for a long time, avoid frequent starting, improve the water-purifying machine of the band pressure-pot of working state of system.
Technical scheme of the present invention is: the circuit card that includes reverse osmosis membrane filter, pressure-pot, high-voltage switch gear, water tap and be connected with high-voltage switch gear, be connected by pure water output water route between reverse osmosis membrane filter and the water tap, wherein high-voltage switch gear is installed on the pure water output water route between reverse osmosis membrane filter and the water tap, pressure-pot is installed in the bypass in the pure water output water route between reverse osmosis membrane filter and the water tap, being connected between pressure-pot and the water tap is equipped with under meter on the water route, automatically controlled plate is electrically connected with high-voltage switch gear and under meter.
The water inlet of above-mentioned reverse osmosis membrane filter is connected with strainer.
Be provided with preposition activated char filter between above-mentioned reverse osmosis membrane filter and the strainer.
Be provided with topping-up pump between above-mentioned strainer and the preposition activated char filter.
The wastewater effluent mouth of above-mentioned reverse osmosis membrane filter is connected with waste water and compares magnetic valve.
Above-mentioned strainer is the cotton strainer of PP.
Above-mentioned waste water is connected with automatically controlled plate than magnetic valve.
The present invention is owing to adopt the structure that is provided with under meter, and by the water level of under meter induction pressure jar, during operation, when pressure reached the pressure cut off value of high-voltage switch gear setting, system was out of service; When the elevation of water surface of pressure-pot reached the reset values of under meter setting, system began to restart.To disconnect, reset values separately control, avoid system to be in inefficient operation interval for a long time, cause frequent starting, improved the working order of system, and prolonged the work-ing life of electrical element, water purification element.The present invention is that a kind of design is ingenious, excellent property, convenient and practical water-purifying machine.

Embodiment
Embodiment:
Structural representation of the present invention such as Fig. 1, shown in 2, include reverse osmosis membrane filter 1, pressure-pot 3, high-voltage switch gear 4, water tap 7 and the circuit card 8 that is connected with high-voltage switch gear 4, be connected by pure water output water route between reverse osmosis membrane filter 1 and the water tap 7, wherein high-voltage switch gear 4 is installed on the pure water output water route between reverse osmosis membrane filter 1 and the water tap 7, pressure-pot 3 is installed in the bypass in the pure water output water route between reverse osmosis membrane filter 1 and the water tap 7, being connected between pressure-pot 3 and the water tap 7 is equipped with under meter 6 on the water route, automatically controlled plate 8 is electrically connected with high-voltage switch gear 4 and under meter 6.
In the present embodiment, for guaranteeing the sanitation and hygiene of pure water, the water inlet of above-mentioned reverse osmosis membrane filter 1 is connected with strainer 9, is provided with preposition activated char filter (10) between reverse osmosis membrane filter 1 and the strainer 9.Above-mentioned strainer 9 is the cotton strainer of PP.
In addition, for improving pressure of supply water, be provided with topping-up pump 2 between above-mentioned strainer 9 and the preposition activated char filter 10.
For ease of the discharge of control waste water, the wastewater effluent mouth of above-mentioned reverse osmosis membrane filter 1 is connected with waste water than magnetic valve 5, and waste water is connected with automatically controlled plate 8 than magnetic valve 5.
During works better of the present invention; tap water is by the cotton strainer 9 of PP, preposition activated char filter 10; topping-up pump 2, enter reverse osmosis membrane filter 1; the waste water that produces is drained than magnetic valve 5 through waste water, and pure water enters pressure-pot 3 through high-voltage switch gear 4, when high-voltage switch gear 4 induced pressure-pots 3 hydraulic pressure reach default pressure cut off value; send instruction by automatically controlled plate 8; waste water is opened than magnetic valve 5, and topping-up pump 2 quits work, and total system enters stopped status.
The tap 7 of fetching boiling water when water demand takes place, the water in the pressure-pot 3 flows out by under meter 6 and post active carbon filter 11.When the water yield of under meter 6 record reached the system reset value of setting, under meter 6 sends instruction by automatically controlled plate 8 made system start system water, and under meter 6 record zero clearings follow-uply repeat above-mentioned work.
